Payroll in Singapore looks simple on paper — a single national social-security scheme (CPF), a well-documented set of statutory contributions, and a mature tax-reporting infrastructure — but employers routinely trip up on the details. Wrong CPF ceilings, missed IR8A submissions, or unmanaged foreign-worker levies quickly turn into penalties, back-payments and reputational drag with regulators.
This 2026 guide covers the current CPF rates, the statutory filings every Singapore employer must complete, and the practical operating disciplines that keep payroll clean.
The Core Statutory Framework
Employer payroll obligations in Singapore rest on three statutes:
- Employment Act 1968 — General terms of employment, notice periods, leave, overtime
- Central Provident Fund Act 1953 — CPF contributions, ceilings, allocations
- Income Tax Act 1947 — Employer’s annual IR8A / Auto-Inclusion Scheme (AIS) reporting
Alongside these, foreign-worker specific rules under the Employment of Foreign Manpower Act 1990 govern quota, levy, and pass conditions. See our companion piece on Singapore Work Permit eligibility and levy.
CPF Contribution Rates (2026)
CPF contributions apply only to Singapore Citizens and Permanent Residents. Foreign employees on EP, S Pass, Work Permit, EntrePass or PEP do not contribute to CPF but their salaries are subject to Skills Development Levy (SDL) and, for the foreign-worker categories, foreign worker levies.
For SC and PR employees aged below 55, the standard rate for 2026 is:
- Employer: 17% of Ordinary Wages, capped at OW ceiling
- Employee: 20% of Ordinary Wages
Rates step down progressively for older employees (55–60, 60–65, 65–70, and above 70). PR employees in their first two years pay graduated rates.
Ordinary Wage Ceiling
From 1 January 2026, the OW ceiling has completed its multi-year uplift to S$8,000 per month. Only OW up to S$8,000 attracts CPF; wages above that ceiling do not.
Additional Wage (AW) Ceiling
Bonuses and other non-monthly wages (Additional Wages) are subject to an annual AW ceiling calculated as: S$102,000 minus total OW subject to CPF for the calendar year. The AW ceiling ensures that highly-paid employees receive CPF contributions on no more than S$102,000 of total wages per year.
Skills Development Levy (SDL)
Every employer pays SDL on the wages of every employee (SC, PR, and foreign) up to a monthly wage ceiling of S$4,500. The rate is 0.25% with a minimum of S$2 and a maximum of S$11.25 per employee per month. SDL is a statutory levy, not a CPF contribution, and is collected via the CPF portal in a single monthly transaction.
Foreign Worker Levy
Employers of Work Permit and S Pass holders pay a foreign worker levy that varies by sector (construction, marine, process, manufacturing, services) and by dependency tier. See MOM’s official foreign worker levy calculator for the current rates.
EP and EntrePass holders are not subject to foreign worker levy.
Employer Payroll Deadlines
- 14th of each month — CPF and SDL contributions for the preceding month due
- 1 March annually — IR8A forms submitted via Auto-Inclusion Scheme (AIS) for all employees; IR8A must be issued to employees who left mid-year within one week of last day
- Before each new hire’s first day — SC/PR nomination, work-pass validity check
- Within one month of hire — Foreign worker levy commencement
- Within two months of departure — For foreign employees, employer must file an IR21 tax clearance and withhold final payment until IRAS clears it
Auto-Inclusion Scheme (AIS)
All employers with five or more employees must register for AIS. AIS-registered employers submit annual income data electronically by 1 March; individual employees no longer need to include employment income in their own tax filings because IRAS has already received it. AIS is administered by IRAS via the IRAS Employer Portal.
Employee Benefits Included in CPF Calculations
Wages subject to CPF include: basic salary, overtime pay, allowances (transport, meal, housing paid in cash), commission, and payments in lieu of leave. Wages that do not attract CPF include: gifts in kind, reimbursements of actual expenses, benefits provided in kind, employer contributions to non-CPF retirement schemes.
Correctly identifying what is or isn’t OW / AW matters because wrong classifications create back-CPF liabilities that CPF Board will audit and recover with late-payment interest.
Common Employer Mistakes
1. Treating allowances as non-CPF
Cash allowances (transport, meal, housing) are generally OW and subject to CPF. Reimbursements against actual expenses are not. Employers who convert reimbursements into fixed allowances trigger CPF obligations without realising.
2. Missing the tax clearance for departing foreigners
Under the Income Tax Act, an employer of a foreign employee who is leaving Singapore or ceasing employment must file IR21 at least one month before the last day and withhold final payment (salary, bonus, leave encashment) until IRAS gives clearance. Failure to do so makes the employer liable for the employee’s outstanding tax.
3. Forgetting the PR graduated rates
New PRs in their first two years pay graduated CPF rates. Employers often default them to full SC rates and end up over-contributing.
4. Overlooking the AW ceiling
When bonuses are paid at year end, employers sometimes CPF-contribute the full amount without applying the AW ceiling. The excess is a CPF over-contribution that requires refund applications.
5. Not registering for AIS on hitting five employees
The AIS threshold is automatic — once you have five or more employees on 31 December, you are required to be on AIS for the following year. Manual IR8A submissions post-threshold are administratively wrong and trigger IRAS notice.
Late-Payment Penalties
CPF late-payment penalties apply from the 15th of the month:
- 1.5% per month interest on outstanding CPF (compounded), minimum S$5 charge per employee per month of arrears
- SDL late-payment: 10% flat penalty on unpaid amount
- AIS or IR21 non-compliance: administrative composition fines from IRAS, escalating to prosecution in serious cases
Operating Disciplines That Prevent Payroll Failures
- Monthly payroll checklist — Reviewed and signed off by two people (preparer + reviewer)
- Master employee data spreadsheet — Citizenship, PR date, work-pass number, DOB, CPF status recorded and updated at each life event
- Reconciliation to bank — Salary paid via bank matches payroll register within two working days of each pay cycle
- Annual IR8A dress rehearsal in February — Draft IR8A run before the 1 March deadline to catch errors
- Departing-foreigner protocol — Standard operating procedure for IR21 filing and withholding
- Quarterly reconciliation to CPF statements — Ensures CPF portal balances match employer records
Related Filings the Payroll Team Should Track
Beyond CPF and IRAS, the payroll function interacts with other statutory calendars:
- The overall company compliance calendar — because payroll dates sit alongside AGM, XBRL, tax filings
- Statutory records for dormant entities that still have single employees — see our dormant company statutory records guide
- Data-protection obligations under PDPA when handling employee data — HR records are personal data and must be inventoried and secured
Final Thoughts
Payroll and CPF is not a place to save money by cutting corners. The system is well-designed, the rates are stable, the deadlines are predictable, and the penalties for missing them are punishing. Investing in a clean payroll operation — whether run in-house or outsourced — pays for itself within the first missed deadline.
