What You Need to Know About Singapore Payroll Tax

Singapore's Central Provident Fund system is unlike payroll in most countries: combined CPF contributions for citizens under 55 total 37% of wages (20% employee, 17% employer), making it one of the highest mandatory savings rates in Asia. Add the Skills Development Levy for every worker and the unique fact that Singapore does not withhold income tax monthly from salaries, and you have a payroll model that demands its own playbook. This guide covers CPF calculations, SDL, IR8A reporting, and the deadlines you need to hit.

1. What is payroll tax?

Payroll tax in Singapore covers the mandatory contributions and levies that employers must manage when paying employees. The main components are:

Central Provident Fund (CPF): A comprehensive social security savings plan. Both employer and employee make contributions based on the employee's wages
Skills Development Levy (SDL): A compulsory levy paid by employers for all employees to fund workforce training and upgrading
Income Tax (Monthly): Singapore does not use a withholding-at-source system for most employees. Instead, employees file their own annual income tax returns. However, employers must report employee earnings to IRAS annually

Unlike many countries, Singapore does not withhold income tax from employee salaries each month (except for foreign employees departing Singapore). Employers report earnings, and employees settle their own tax.

2. Who does it apply to?

This usually applies to:

All employers in Singapore
Singapore citizens and permanent residents (for CPF contributions)
All employees, including foreign workers (for SDL)
Foreign employees leaving Singapore (for tax clearance withholding)
Employers of part-time, full-time, and contract workers

3. Why does it matter?

Understanding payroll tax helps you:

Stay compliant with CPF Board and IRAS requirements
Avoid penalties for late or incorrect CPF contributions
Keep proper records of all employee earnings and contributions
File and pay correctly by the required deadlines
Plan your cash flow better by budgeting for employer CPF and SDL costs

4. How does it work?

Here's the basic process:

Register as an employer with CPF Board and IRAS
Determine each employee's CPF contribution rates based on their age, citizenship status, and wages
Calculate CPF contributions (employee and employer portions) and SDL each month
Deduct the employee's CPF contribution from their wages
Pay the total CPF contributions (both employer and employee portions) and SDL to CPF Board by the 14th of the following month
At year-end (by 1 March), submit Form IR8A and related appendices to IRAS reporting each employee's total earnings
For foreign employees leaving Singapore, file Form IR21 for tax clearance at least one month before their departure

5. What forms are involved?

Form IR8A (Return of Employee's Remuneration) - Filed annually with IRAS by 1 March, reporting each employee's total employment income for the previous year
Appendix 8A - Reports details of benefits in kind provided to employees
Appendix 8B - Reports details of stock option or share gains
Form IR21 (Tax Clearance) - Filed when a foreign employee ceases employment or leaves Singapore. Must be filed at least one month before the employee's last day
CPF Submission - Monthly contribution details submitted to CPF Board, typically through CPF EZPay or your payroll software

6. What information do you need?

Before handling payroll tax, make sure you have:

CPF employer submission number
Employee NRIC or FIN numbers
Employee citizenship status (Singapore citizen, permanent resident, or foreigner)
Employee date of birth (CPF rates vary by age)
Monthly ordinary wages (OW) and additional wages (AW) for each employee
Details of benefits in kind provided to employees
Access to CPF EZPay and IRAS myTax Portal

7. Important deadlines

CPF contributions: Due by the 14th of the following month. If the 14th falls on a weekend or public holiday, the due date is the next business day
SDL contributions: Paid together with CPF contributions by the 14th of the following month
Form IR8A filing: By 1 March each year for the previous calendar year's earnings
Form IR21 (tax clearance): At least 1 month before a foreign employee's last day of employment or departure from Singapore
Auto-Inclusion Scheme (AIS): Employers with 5 or more employees, or who have been notified by IRAS, must submit IR8A electronically by 1 March

8. Common mistakes to avoid

Paying CPF contributions late (a late-payment interest of 1.5% per month applies, with a minimum of S$5)
Not adjusting CPF rates when an employee reaches a new age bracket (rates decrease at ages 55, 60, 65, and 70)
Forgetting to cap CPF contributions at the monthly ordinary wage ceiling of S$8,000 (2026)
Not filing Form IR21 for departing foreign employees (you can be held liable for their unpaid tax)
Overlooking benefits in kind when reporting on Form IR8A
Not including additional wages (bonuses, commissions) in CPF calculations (subject to the annual wage ceiling of S$102,000)
Paying SDL only for local employees (SDL applies to all employees, including foreign workers)

9. Simple example

You employ one Singapore citizen aged 30 with a monthly salary of S$5,000.

Employee deductions (from their pay):

CPF employee contribution (20%): S$1,000

Employer costs (on top of salary):

CPF employer contribution (17%): S$850
SDL (0.25% of total wages, minimum S$2, maximum S$11.25): S$11.25

Total monthly employer cost: S$5,000 salary + S$850 CPF + S$11.25 SDL = S$5,861.25

Total CPF submitted to CPF Board monthly: S$1,000 (employee) + S$850 (employer) = S$1,850

Employee takes home: S$5,000 - S$1,000 = S$4,000

The employee does not have income tax withheld each month. They will file their own income tax return after year-end and pay any tax due directly to IRAS.

10. FAQ

Q: What are the CPF contribution rates? A: For Singapore citizens aged 55 and below, the total CPF contribution is 37% (20% employee, 17% employer). Rates decrease for older employees. Permanent residents in their first and second year have graduated lower rates.

Q: Does Singapore withhold income tax from salaries? A: No. Unlike most countries, Singapore does not have a monthly income tax withholding system. Employees file their own annual tax returns and pay tax directly to IRAS. The exception is foreign employees leaving Singapore, where employers must withhold pay for tax clearance.

Q: What is the CPF ordinary wage ceiling? A: The monthly ordinary wage (OW) ceiling is S$8,000 in 2026. CPF contributions are only calculated on ordinary wages up to this limit. The annual salary ceiling (ordinary wages plus additional wages) is S$102,000.

Q: Do I pay CPF for foreign employees? A: No. CPF contributions only apply to Singapore citizens and permanent residents. However, SDL applies to all employees, including foreign workers on work permits, S passes, and employment passes.

Q: What happens if I pay CPF late? A: CPF Board charges a late-payment interest of 1.5% per month (minimum S$5) on overdue contributions. Persistent late payment can result in enforcement action, including court proceedings.

11. Final takeaway

Singapore payroll involves CPF contributions (20% employee, 17% employer for citizens under 55), SDL for all employees, and annual reporting to IRAS via Form IR8A. Pay CPF and SDL by the 14th of each month, and file IR8A by 1 March each year.
