Global Payroll Services in Thailand:Automated & Compliant RD Tax Management
Thailand Payroll Runs on Three Systems at Once: Tax, SSO, and Labor Records
Payroll in Thailand is more than a monthly bank transfer. Employers must calculate salary in Thai Baht, withhold personal income tax, deduct employee Social Security Fund contributions, calculate employer SSO contributions, prepare payslips, manage PND.1 filings, update employee records, track minimum wage by province or sector, and handle payroll-sensitive events such as overtime, maternity leave, resignation, and severance.
NNRoad provides Thailand payroll services for companies that already have a local employer structure in Thailand, such as a Thai company, branch, subsidiary, representative office, or other entity permitted to employ staff directly. Your company remains the legal employer, while NNRoad supports monthly payroll calculation, payroll reporting, compliance workflow, and payroll documentation.
When this Thailand payroll service is the right fit
- Your company already has a Thai legal entity and needs monthly payroll outsourcing support.
- You are hiring employees in Bangkok, Chonburi, Rayong, Phuket, Chiang Mai, Samut Prakan, Pathum Thani, or other Thai employment locations.
- Your regional HR or finance team needs clear payroll reports showing gross pay, PIT withholding, SSO, net salary, and employer cost.
- You need support with PND.1, annual PND.1 Gor data, withholding tax certificates, SSO calculations, payslips, and payroll records.
- You are moving from manual spreadsheet payroll to a more controlled outsourced payroll process.
- You employ Thai employees, foreign employees, shift workers, sales staff, hospitality staff, or employees with variable pay and allowances.
When payroll outsourcing is not enough
Payroll outsourcing is designed for companies that already have a compliant local employer. If your company does not have a Thai entity but wants to hire an employee in Thailand, standalone payroll outsourcing may not solve the legal employer issue. In that case, review NNRoad’s Thailand Employer of Record service.
If the case involves a foreign national working in Thailand, payroll should also be aligned with work permit, visa, tax, social security, and employment documentation. For foreign-national employment support, review Thailand Expat Employment services. For companies managing payroll across several countries, Thailand payroll can also be connected to NNRoad’s Global Payroll service.
Thailand Payroll Calculation Map: From Gross Salary to Net Pay
A Thailand payroll service provider should make the pay run easy to review. Payroll should separate gross salary, taxable income, employee deductions, employer contributions, net pay, and filing data. This is especially important for foreign headquarters because the Thai payroll result may not look like payroll in Singapore, Vietnam, China, the UK, or the United States.
Core payroll components employers need to control
| Payroll component | How it affects payroll | Why it matters |
|---|---|---|
| Gross salary and wage items | Base salary, overtime, allowances, bonus, commission, incentive pay, taxable benefits, and one-off payments form the starting point of payroll. | Incorrect classification can affect PIT, SSO, payslips, annual certificates, and severance-related calculations. |
| Employee Social Security Fund contribution | The employee-side SSO contribution is deducted from salary based on the statutory contribution base and cap. | This reduces employee net pay and is also relevant to personal income tax calculation. |
| Personal income tax withholding | The employer estimates and withholds monthly PIT based on employee income, deductions, allowances, and annualized tax liability. | Wrong PIT withholding can create employee complaints, year-end tax issues, and Revenue Department exposure. |
| Employee net salary | Net salary is calculated after PIT, employee SSO, and other lawful or agreed deductions. | This is the amount employees usually compare against their offer or monthly expectation. |
| Employer SSO contribution | The employer contributes an equal Social Security Fund amount under the applicable rate and cap. | This is an employer-side cost and should be reported separately from employee deductions. |
| Workmen’s Compensation Fund | The employer may have annual WCF obligations based on risk classification and wages. | This is not usually an employee deduction but should be included in employer cost planning. |
| Employee Welfare Fund or provident fund | From October 2026, some employers may need EWF contributions unless an exemption applies through provident fund or comparable assistance. | This can change both employer cost and employee payroll deduction settings. |
What NNRoad supports in each pay cycle
- Monthly gross-to-net salary calculation in THB.
- Employee PIT withholding calculation and payroll tax report preparation.
- Employee and employer SSO contribution calculation.
- Payroll reports for HR, finance, and management approval.
- Payslip preparation and employee-facing payroll summaries.
- New hire, leaver, salary change, bonus, allowance, overtime, leave, and final settlement payroll handling.
- Payroll records that can support PND.1, SSO, annual withholding certificate, and internal accounting needs.
Why a generic payroll template is risky in Thailand
Thailand payroll has its own combination of progressive PIT withholding, social security caps, province-based daily minimum wage, labor-law pay rules, foreign employee work permit requirements, and upcoming Employee Welfare Fund obligations. A payroll template copied from another country may calculate the wrong net pay, apply the wrong contribution cap, or miss a required record.
The 2026 SSO Ceiling Change: Small Monthly Difference, Big Payroll Configuration Issue
The Social Security Fund ceiling change is one of the most important Thailand payroll updates for 2026. The contribution rate remains 5% for both the employer and employee, but the maximum wage base used for contribution calculation increased from THB 15,000 to THB 17,500 from January 1, 2026. This raises the maximum monthly contribution from THB 750 to THB 875 per side during the 2026 to 2028 phase.
2026 to 2032 SSO ceiling roadmap
| Period | Maximum monthly wage base | Maximum employee contribution | Maximum employer contribution | Payroll note |
|---|---|---|---|---|
| 2026 to 2028 | THB 17,500 | THB 875 | THB 875 | Payroll systems should already be updated for the new cap. |
| 2029 to 2031 | THB 20,000 | THB 1,000 | THB 1,000 | Employers should forecast the later increase in cost and employee deductions. |
| 2032 onward | THB 23,000 | THB 1,150 | THB 1,150 | The highest contribution cap applies from this phase onward. |
What changes for employees earning above the old cap
Employees earning THB 17,500 or more per month will generally see their employee SSO deduction increase by THB 125 per month compared with the old THB 750 cap. Employers also match the increase on the employer side. The amount may look small per employee, but it becomes material for companies with larger Thailand headcount.
SSO setup items to validate
- Company SSO registration status.
- Employee SSO registration and employee master data.
- Correct monthly wage base and contribution cap.
- Foreign employee work permit status where relevant.
- New employee and resigned employee SSO forms.
- Monthly SSO report and payment reconciliation.
- Employee payslip display of SSO deduction.
Official reference point
Employers should review the Social Security Office and update payroll systems for the revised wage ceiling. The payroll report should show employee SSO and employer SSO separately so finance can see both net-pay impact and employer-cost impact.
PND.1, 50 Tawi, and PND.1 Gor: The Thai Payroll Tax Paper Trail
Thailand payroll tax compliance depends on a recurring paper trail. The monthly pay run feeds the PND.1 withholding return. The annual payroll year-end summary feeds PND.1 Gor. Employees need withholding tax certificates, often referred to as 50 Tawi, so they can file their own personal income tax returns correctly.
Monthly and annual payroll tax workflow
| Payroll tax item | Purpose | Typical timing | Payroll control |
|---|---|---|---|
| PND.1 | Monthly withholding tax return for employment income and certain hire-of-work payments. | Generally by the 7th of the following month for paper filing, or by the 15th for online filing under the extended e-filing framework. | Payroll should be finalized early enough to calculate withholding and prepare filing data. |
| Employee withholding tax certificate | Certificate showing income paid and tax withheld for the employee. | Usually prepared for year-end employee tax filing and leaver situations. | Monthly payroll records should be accurate so certificates are not corrected later. |
| PND.1 Gor | Annual summary of payroll withholding tax filed and paid during the year. | Within February of the following year for paper filing, or by March 8 for online filing. | Year-end payroll reconciliation should begin before the deadline month. |
| Employee annual PIT filing | Employees may need to file personal income tax returns depending on income and facts. | Generally by March 31 for hardcopy filing and April 8 for online filing. | Payroll should provide accurate income and withholding data for employees. |
Thailand PIT bands used in payroll planning
| Annual net taxable income | PIT rate | Payroll note |
|---|---|---|
| THB 0 to 150,000 | Exempt | First taxable band after deductions and allowances. |
| THB 150,001 to 300,000 | 5% | Low-income taxable bracket. |
| THB 300,001 to 500,000 | 10% | Common bracket for many junior to mid-level employees after deductions. |
| THB 500,001 to 750,000 | 15% | Often relevant for professional and managerial employees. |
| THB 750,001 to 1,000,000 | 20% | Net salary may change materially when employees move into this bracket. |
| THB 1,000,001 to 2,000,000 | 25% | Relevant for senior staff and expatriate employees. |
| THB 2,000,001 to 5,000,000 | 30% | High-income bracket requiring careful annualized withholding. |
| Over THB 5,000,000 | 35% | Top PIT bracket for high earners. |
Official tax reference point
Employers can review the Thai Revenue Department for forms, e-filing, and tax guidance. Payroll reports should reconcile monthly PND.1 data, employee withholding, annual summaries, and employee certificates before the year-end filing period.
Minimum Wage in Thailand Is a Location and Sector Question
Thailand does not operate payroll using a single national monthly minimum wage. The minimum wage is a daily rate that depends on province, district, and in some cases sector. Payroll must therefore connect each employee’s work location and job arrangement with the correct minimum daily wage rate.
Current minimum wage structure to check before payroll
| Payroll situation | Minimum wage control | Why it matters |
|---|---|---|
| Bangkok employees | THB 400 per day applies across all business types under the current July 2025 schedule. | Bangkok payroll templates using older THB 372 assumptions should be updated. |
| Employees in Phuket, Chachoengsao, Chonburi, Rayong, or Koh Samui district | THB 400 per day applies under the listed provincial or district schedule. | These locations are common for tourism, manufacturing, logistics, and service roles. |
| Hotel businesses type 2, 3, and 4 nationwide | THB 400 per day applies nationwide for covered hotel businesses. | Hospitality payroll should check business classification, not only province. |
| Entertainment establishments nationwide | THB 400 per day applies nationwide for covered entertainment venues. | Sector classification can override the ordinary provincial payroll assumption. |
| Other provinces and districts | Rates vary by province or district, generally within the THB 337 to THB 400 schedule. | Payroll should validate work location before setting hourly or daily wage rates. |
Minimum wage affects more than base pay
A daily wage change can affect hourly pay, overtime, holiday work, unpaid leave proration, absence calculation, salary adjustment budgets, and employee communication. For employers with employees across multiple provinces, payroll should not use one Bangkok rate for every location unless the business and employee facts support that treatment.
Payroll controls for multi-location employers
- Map each employee to their actual work location.
- Identify whether the employee works in a covered hotel or entertainment business.
- Check hourly, daily, casual, and part-time workers against the correct daily wage rate.
- Review overtime and holiday work calculations after any wage update.
- Document the wage rate used in the payroll file.
Official reference point
Employers should review the Thailand Ministry of Labour and current Wage Committee notifications before finalizing wage floors, especially where the employee works outside Bangkok or in hospitality, tourism, manufacturing, logistics, retail, or entertainment.
Thailand Payroll Example: Why Net Pay and Employer Cost Need Separate Views
Payroll reports should show both employee net pay and employer cost. Employees usually care about net salary after PIT and SSO. Finance teams need to see gross salary, employer SSO, workmen’s compensation exposure, provident fund or EWF treatment, and any additional payroll-linked costs.
Illustrative gross-to-net example
The example below is simplified and assumes a standard Thailand employee earning THB 80,000 per month, with no spouse or child allowances, no provident fund, no additional deductions, and Social Security Fund contribution capped at THB 875 per month under the 2026 to 2028 ceiling. Actual payroll may differ depending on employee allowances, tax deductions, bonuses, salary timing, provident fund, work location, foreign employee status, and current legal updates.
| Payroll item | Illustrative amount | Explanation |
|---|---|---|
| Gross monthly salary | THB 80,000 | Salary before employee deductions and tax withholding. |
| Employee SSO | THB 875 | 5% applied up to the 2026 to 2028 wage ceiling of THB 17,500. |
| Estimated monthly PIT withholding | Approximately THB 6,075 | Simplified annualized calculation using standard employment expense deduction, personal allowance, and PIT brackets. |
| Estimated employee net pay | Approximately THB 73,050 | Gross salary minus employee SSO and estimated PIT withholding. |
| Employer SSO | THB 875 | Employer-side Social Security Fund contribution under the same ceiling. |
| Estimated employer cost before other items | THB 80,875 | Gross salary plus employer SSO, excluding WCF, provident fund, EWF, benefits, payroll provider fees, and leave or severance liabilities. |
Why the example may change in real payroll
- Provident fund contributions may reduce taxable income and change net pay.
- Bonus or commission payments can change annualized PIT withholding.
- Foreign employees may have offshore compensation, tax residence, or work permit-linked salary considerations.
- Employee Welfare Fund contributions may apply from October 2026 if the employer is not exempt.
- Workmen’s Compensation Fund contribution is employer-only and depends on risk classification.
- Allowances and benefits may be taxable, exempt, or treated differently depending on structure.
Use payroll reports to prevent offer misunderstandings
If an employment offer is discussed in net salary terms, the employer should model the full-year payroll result before signing the offer letter. Thailand PIT withholding can be affected by annualization, deductions, allowances, provident fund, bonuses, and taxable benefits. Net-to-gross modeling should be done before the employee starts, not after the first payslip is disputed.
The October 2026 Employee Welfare Fund Question
Thailand’s Employee Welfare Fund is becoming a practical payroll planning issue for employers. From October 1, 2026, some employers with at least 10 employees may be required to register employees and contribute to the fund if they do not provide a qualifying provident fund or comparable assistance arrangement.
What employers should check before October 2026
| Question | Why it matters for payroll |
|---|---|
| Does the company have at least 10 employees? | The Employee Welfare Fund requirement is expected to apply to employers meeting the employee-count threshold unless an exemption applies. |
| Does the company already provide a registered provident fund? | A qualifying provident fund may allow exemption from EWF participation if it covers the relevant employees properly. |
| Does every employee participate in the provident fund? | If probationary or certain employee groups are excluded, those employees may still need separate review. |
| Does the company provide comparable assistance? | A recognized comparable arrangement may affect whether EWF registration is required. |
| Is payroll configured for employee and employer contributions? | If EWF applies, both employee deductions and employer contributions must be calculated and remitted. |
Expected contribution logic
For covered employees, the expected contribution rate from October 1, 2026 to September 30, 2031 is 0.25% of wages from the employee and 0.25% from the employer. From October 1, 2031 onward, the rate is expected to rise to 0.50% from each side. Employers should keep monitoring final implementation guidance before the first EWF pay cycle.
Payroll preparation checklist
- Review employee count and covered employee categories.
- Review whether the company has a provident fund or comparable arrangement.
- Confirm whether probationary employees, fixed-term employees, and foreign employees are covered.
- Update payroll templates to support employee deduction and employer contribution lines.
- Prepare employee communication before deductions begin.
- Reconcile EWF treatment with severance, termination, and benefits policies.
Why EWF should be planned with total rewards
The EWF is not just a payroll deduction. It may affect how the company structures provident fund participation, employee retention benefits, termination assistance, and payroll cost forecasting. Companies that already have a provident fund should review whether the fund design actually creates an exemption for all relevant employees.
Payroll-Sensitive Leave, Overtime, and Severance Items
Many Thailand payroll errors occur outside the base salary line. Overtime, holiday work, annual leave, maternity leave, paternity or spouse leave, sick leave, business leave, unpaid leave, severance, and payment in lieu of notice all require careful payroll treatment.
Common labor-law-linked payroll items
| Payroll item | Payroll question to ask | Why it matters |
|---|---|---|
| Overtime on working days | Was overtime approved, recorded, and calculated using the correct hourly basis? | Overtime generally requires premium pay and affects PIT, SSO wage base, and payslip transparency. |
| Holiday work and holiday overtime | Is the work performed during normal holiday hours or overtime hours on a holiday? | Different premium pay treatment may apply depending on the work situation. |
| Annual leave | Has leave entitlement, use, carry-forward, and unused leave at termination been tracked? | Leave balances affect monthly salary and final settlement. |
| Maternity leave | Is the payroll setup updated for the 120-day leave and employer-paid portion? | From the latest labor-law changes, the employer-paid maternity portion has increased, affecting payroll cost and leave tracking. |
| Paternity or spouse childbirth leave | Does the employee qualify for paid spouse leave connected to childbirth? | New family-leave rules affect payroll and attendance records. |
| Unpaid leave | How many payroll days and SSO-reporting days are affected? | Incorrect unpaid leave treatment can change salary, SSO, and tax withholding. |
| Severance | Does the termination reason and service period create statutory severance entitlement? | Severance can become one of the largest payroll-linked employer liabilities. |
Severance table for payroll planning
| Length of service | Typical statutory severance reference | Payroll planning note |
|---|---|---|
| 120 days to less than 1 year | 30 days’ wages | Short-service employees may still create severance liability if termination qualifies. |
| 1 year to less than 3 years | 90 days’ wages | Relevant for employees past the first full year of service. |
| 3 years to less than 6 years | 180 days’ wages | Termination cost becomes more material in this band. |
| 6 years to less than 10 years | 240 days’ wages | Employers should forecast severance exposure for long-service employees. |
| 10 years to less than 20 years | 300 days’ wages | Senior and long-service employees may carry significant termination liability. |
| 20 years or more | 400 days’ wages | Highest statutory severance tier under current labor-law practice. |
Final settlement checklist
- Final salary up to the last working day.
- Unused annual leave payment where applicable.
- Severance pay where the termination qualifies.
- Payment in lieu of notice where applicable.
- Outstanding bonus, commission, allowance, or approved incentive payment.
- Employee loans, salary advances, or lawful deductions.
- Final SSO and tax withholding treatment.
- Withholding tax certificate and leaver payroll records.
Payroll should not calculate leaver pay without HR facts
A resignation, ordinary termination, termination for cause, retirement, redundancy, business relocation, or fixed-term expiry may lead to different payroll results. Before approving final payroll, HR and payroll should agree on termination reason, last working day, notice period, unpaid leave, unused leave, and any severance entitlement.
Foreign Employees in Thailand: Payroll Must Match Work Permit Reality
Foreign employee payroll in Thailand should be reviewed before the first salary payment. Payroll treatment may be affected by work permit status, visa type, local employment contract, salary payment location, Social Security Fund eligibility, tax residence, and whether part of the compensation is paid offshore.
Foreign employee payroll questions to resolve before onboarding
- Does the employee have the correct visa and work permit to perform the role in Thailand?
- Is the work permit tied to the correct employer, job title, workplace, and approved activities?
- Will the employee be paid fully through Thai payroll or partly through an overseas payroll?
- Is the employee receiving housing, relocation, school fees, home leave, tax equalization, or other expatriate benefits?
- Should the employee be registered for Thai Social Security Fund contributions?
- Is the employee a Thai tax resident, non-resident, assignee, or short-term worker?
- Will offshore income related to Thai work need payroll or tax review?
- Is a departure payroll or final tax review needed before the employee leaves Thailand?
Thai work permit records should match payroll records
Foreign employee payroll should not show a salary, employer, role, or work location that conflicts with work permit and employment documentation. If the employee’s role, employer, workplace, or salary changes, HR should review whether the work permit and payroll records also need updates.
Payroll and work authorization should be coordinated
Thailand’s Department of Employment operates the e-Work Permit system. If your company needs to hire or relocate a foreign national to Thailand, review Thailand Expat Employment services. If your company does not have a Thai entity, review Thailand Employer of Record services before choosing standalone payroll outsourcing.
Thailand Payroll Calendar: Two Monthly Deadlines and One Year-End Close
A strong Thailand payroll process should be built around a monthly operating calendar. Payroll is not complete when employees are paid. Employers must also prepare PND.1 withholding tax filings, SSO contribution reports, payslips, payment records, accounting journals, and year-end payroll summaries.
Recommended monthly payroll workflow
| Payroll stage | What happens | Employer action |
|---|---|---|
| Payroll cut-off | Collect new hires, leavers, salary changes, overtime, allowances, bonuses, leave, unpaid absence, deductions, and bank changes. | Submit approved payroll inputs before the agreed cut-off date. |
| Employee record validation | Check tax ID, SSO number, work permit status, employee category, work location, and payroll start or end date. | Resolve missing employee records before payroll calculation begins. |
| Draft calculation | Calculate gross pay, PIT withholding, employee SSO, employer SSO, provident fund or EWF items where relevant, and net salary. | Review draft payroll report and identify unusual changes. |
| Employer approval | Prepare final payroll report, net salary list, deduction summary, and employer cost report. | Approve payroll before payment and statutory filing preparation. |
| Salary payment support | Prepare payment summary or bank file in THB. | Fund payroll and release salary payments through the agreed payment process. |
| Payslip release | Prepare employee payslips showing earnings, deductions, PIT, SSO, and net salary. | Distribute payslips and respond to employee questions using payroll records. |
| PND.1 and SSO reconciliation | Prepare payroll data for monthly tax withholding and social security contribution workflows. | Reconcile payroll report, filing data, and payment evidence. |
| Month-end close | Finalize accounting entries, cost center allocation, and payroll variance review. | Retain reports for finance review, audit, and year-end payroll filings. |
Why the filing calendar matters
Monthly PND.1 filing and SSO contribution payment are separate workflows. Payroll teams should not assume that completing salary payment means statutory compliance is complete. A controlled calendar helps the employer meet tax and social security obligations without last-minute corrections.
Year-end payroll close
At year end, employers should reconcile monthly PND.1 filings, annual PND.1 Gor data, employee withholding tax certificates, SSO wage reports, leaver records, employee benefits, and year-to-date payroll totals. A clean monthly payroll process makes year-end work easier and reduces the risk of correcting certificates after employees have already filed their own tax returns.
Thailand Payroll Setup Pack for Local Entities
A clean Thailand payroll launch depends on accurate setup data. Missing tax IDs, incomplete SSO registration, outdated minimum wage settings, unclear allowance treatment, or missing year-to-date payroll data can create errors in the first pay run.
Company-level setup information
- Thai entity legal name and registration details.
- Tax identification number and Revenue Department filing setup.
- Social Security Office employer registration information.
- Workmen’s Compensation Fund information and business risk classification where available.
- Payroll contact persons and approval workflow.
- Payroll frequency, salary payment date, and monthly cut-off date.
- Bank payment process and salary payment file requirements.
- Provident fund arrangement or Employee Welfare Fund planning status.
- Accounting codes, departments, cost centers, and management reporting format.
- Current payroll provider or in-house payroll handover documents, if applicable.
Employee-level setup information
- Employee full legal name and identification details.
- Thai tax ID and SSO registration number where available.
- Employment contract, start date, job title, work location, and employee category.
- Gross salary, net salary expectation, allowances, bonus plan, commission plan, and benefits.
- Bank details for salary payment.
- Work permit, visa, and immigration documents for foreign employees.
- Provident fund participation or EWF coverage status.
- Leave balance, unpaid leave records, and prior payroll history where relevant.
- Applicable minimum wage location and sector classification.
Monthly payroll input checklist
- New hires and leavers.
- Salary changes and promotion adjustments.
- Allowances, bonuses, commissions, and incentive payments.
- Overtime, holiday work, shift work, and weekend work.
- Paid leave, unpaid leave, sick leave, maternity leave, paternity or spouse leave, and absence records.
- Approved deductions, salary advances, employee loans, or reimbursements.
- Foreign employee work permit or visa changes.
- Cost center, department, or project coding changes.
- Final settlement data for resigning or terminated employees.
Migration review from another provider
If your company is moving from another payroll provider or from manual payroll, NNRoad may request prior payroll reports, employee payslips, PND.1 records, SSO contribution history, annual withholding certificates, PND.1 Gor records, provident fund records, leave balances, benefit lists, and unresolved payroll issues. This helps reduce transition risk before the first live payroll run.
Payroll Outsourcing, EOR, Expat Employment, or On-Demand Talent in Thailand?
Companies often search for a Thailand payroll service provider when they are still deciding how the worker should be engaged. The right route depends on whether your company has a Thai entity, whether the person should be an employee, whether the worker is a foreign national, and whether the engagement is long-term employment or flexible project support.
| Business need | Best-fit NNRoad route | How it connects with payroll |
|---|---|---|
| You already have a Thai entity and need PIT withholding, SSO, PND.1, payslips, annual summaries, and monthly payroll reporting support. | Thailand Payroll Service | Your entity remains the legal employer; NNRoad supports payroll calculation, reporting, and compliance workflow. |
| You want to hire an employee in Thailand but do not have a local legal entity. | Thailand Employer of Record | The EOR model provides a local employment route and includes payroll administration through the local employer structure. |
| You need to hire or relocate a foreign national to work in Thailand. | Thailand Expat Employment | Payroll should be aligned with work permit, visa, tax, SSO, contract, and compensation structure. |
| You need flexible project-based support rather than a standard employment relationship. | Thailand On-Demand Talent | The payment and compliance model may differ from employee payroll and should be reviewed before engagement. |
| You manage payroll in multiple countries and need consolidated reporting. | Global Payroll | Thailand payroll can be connected to a wider multi-country payroll reporting and approval process. |
Do not use payroll outsourcing to solve an entity issue
If your company has no Thai employer structure, payroll outsourcing alone is usually not enough. The first decision should be whether to incorporate, use an EOR, engage a contractor, or choose another compliant workforce route.
Do not process contractors as employees without review
Employees, independent contractors, consultants, freelancers, and outsourced service providers can create different tax, social security, labor-law, and documentation outcomes. If the worker should legally be treated as an employee, Thai payroll, PIT withholding, SSO, labor protection, leave, and severance obligations may apply.
Build a Thailand Payroll Process That Can Handle Regulatory Change
Thailand payroll can look simple when a company has only one or two employees. Complexity grows when the company adds foreign employees, multi-province hiring, bonuses, provident fund, EWF planning, overtime, hospitality or entertainment-sector minimum wage, maternity leave, severance, and year-end withholding certificates.
NNRoad helps employers turn payroll into a structured monthly process. A strong process includes payroll cut-off, employee record validation, gross-to-net calculation, PIT withholding review, SSO cap review, employer cost reporting, payslip delivery, PND.1 preparation, SSO reconciliation, and record retention.
What a stronger Thailand payroll process gives your team
- Clearer gross-to-net and employer-cost reporting.
- Better control over PIT withholding, SSO, PND.1, and annual PND.1 Gor data.
- More reliable handling of the 2026 SSO wage ceiling change.
- Cleaner employee communication when net salary changes.
- Better handling of minimum wage by location and sector.
- Improved coordination for foreign employees and work permit-linked payroll.
- Early preparation for Employee Welfare Fund or provident fund decisions.
- A payroll structure that can support headcount growth across Thailand.
Start with a payroll scope review
To assess your Thailand payroll needs, prepare your Thai entity status, employee count, employee nationalities, work locations, salary structure, payroll frequency, SSO registration status, provident fund or EWF position, current payroll process, and target payroll launch date. NNRoad can then help confirm whether your case fits payroll outsourcing, EOR, expat employment, on-demand talent, or a combined workforce solution.
For broader Thailand workforce planning, you can also review the Thailand country hub or estimate employment cost through the Thailand labor cost calculator.
QUICK FAQs
What does a Thailand payroll service provider do?
A Thailand payroll service provider helps employers calculate salaries, personal income tax withholding, employee SSO, employer SSO, net pay, payslips, payroll reports, PND.1 data, annual withholding summaries, and employee payroll records. For companies with a Thai entity, payroll outsourcing can reduce manual work while the company remains the legal employer.
Does my company need a Thai entity to use payroll outsourcing in Thailand?
In most cases, yes. Thailand payroll outsourcing is designed for companies that already have a compliant local employer structure, such as a Thai company, branch, subsidiary, or registered employer arrangement. If your company does not have a Thai entity but wants to hire an employee in Thailand, an Employer of Record model may be more suitable than standalone payroll outsourcing.
What are the main payroll deductions in Thailand?
The main employee-side payroll deductions in Thailand are personal income tax withholding and employee Social Security Fund contributions. Other deductions may include provident fund contributions, Employee Welfare Fund contributions from October 2026 where applicable, salary advances, employee loans, or lawful agreed deductions. Employer-side payroll costs usually include employer SSO, Workmen’s Compensation Fund, and provident fund or EWF contributions where applicable.
What is the Thailand Social Security contribution rate in 2026?
For 2026 to 2028, Thailand Social Security Fund contributions remain 5% for both employer and employee, but the monthly wage ceiling increased to THB 17,500 from January 1, 2026. This means the maximum monthly contribution is THB 875 from the employee and THB 875 from the employer for employees earning at or above the ceiling.
What is the minimum wage in Thailand?
Thailand minimum wage is not one national monthly salary. It is a daily wage rate that depends on province, district, and sometimes sector. Under the current schedule effective July 1, 2025, rates range from THB 337 to THB 400 per day. Bangkok is THB 400 per day across all business types, and THB 400 also applies to specified hotel businesses and entertainment establishments nationwide.
What is PND.1 in Thailand payroll?
PND.1 is the monthly withholding tax return used for employment income and certain hire-of-work payments. Employers use it to report and remit personal income tax withheld from employees. Paper filing is generally due by the 7th day of the following month, while online filing is generally due by the 15th day under the extended e-filing framework.
How are foreign employees handled in Thailand payroll?
Foreign employee payroll in Thailand should be reviewed together with work permit, visa, local employment contract, salary payment location, tax residence, SSO eligibility, and any expatriate benefits. Employment income connected to work performed in Thailand may be taxable in Thailand even if paid outside Thailand, so split-payroll and offshore compensation arrangements should be reviewed before the first pay run.
When should a company choose Thailand EOR instead of Thailand payroll outsourcing?
A company should choose Thailand Employer of Record services when it wants to hire an employee in Thailand but does not have a local legal entity or compliant employer structure. Payroll outsourcing supports an existing employer. EOR provides a local employment route where the EOR provider acts as the legal employer while the client manages the employee’s daily work, goals, and performance.
