Payroll outsourcing Singapore businesses rely on covers more than just paying salaries. This guide explains what payroll outsourcing Singapore firms provide, what it costs, and how to decide if outsourcing your payroll makes sense for your business.
What payroll outsourcing covers
Outsourced payroll means a third party, typically an accounting or corporate services firm, handles the monthly payroll run and related compliance obligations on your behalf.
What’s typically included
- Monthly payroll processing: calculating gross pay, overtime, and allowances; applying CPF deductions at the correct rates; generating itemised payslips; preparing the bank disbursement file
- CPF administration: submitting employer and employee CPF contributions via CPF e-Submit@web by the 14th of each month; handling age-bracket rate changes and PR graduated rates
- SDL and levies: calculating and including the Skills Development Levy (0.25% of wages, minimum S$2, maximum S$11.25 per employee per month)
- Year-end IR8A filing: preparing and submitting IR8A forms for all employees to IRAS by 1 March, and submitting via AIS for employers with 5 or more employees
Typical add-ons: leave management, expense claim processing, mid-month off-cycle payroll runs, Appendix 8A (benefits in kind), Foreign Worker Levy tracking.
What payroll outsourcing doesn’t cover: employment contracts and HR advisory, MOM work pass applications, retrenchment advice, staff disputes or employment tribunal proceedings.
What payroll outsourcing costs in Singapore
Fees are typically structured per employee per month, with a minimum monthly charge.
| Headcount | Typical monthly cost |
|---|---|
| 1–5 employees | S$100–S$200/month |
| 6–15 employees | S$200–S$450/month |
| 16–30 employees | S$450–S$800/month |
| 31–50 employees | S$800–S$1,500/month |
| 50+ employees | Quoted individually |
Per-employee rates generally run S$15 to S$40 per employee per month. Year-end IR8A costs are typically S$50 to S$150 per employee, or a flat fee for small headcounts. Ask upfront what’s included and what triggers an additional charge.
Payroll software vs payroll outsourcing Singapore: the real comparison
DIY payroll software (Talenox, Payboy, QuickHR, Deskera) costs S$10 to S$30 per employee per month. You do the work — entering pay, approving runs, submitting to CPF. It works well if you have a capable admin person who stays on top of regulatory changes. The risk is regulatory drift: CPF rates change, OW ceilings increase, new MOM requirements come in.
Payroll outsourcing Singapore costs S$15 to S$40 per employee per month. You provide the input data; the provider runs the calculations, generates payslips, handles CPF submission, and keeps current with regulatory changes.
When outsourcing payroll makes clear sense
- You don’t have a dedicated admin or HR person. Payroll done by a founder or director doing five other things is payroll that gets done late, incorrectly, or both.
- Your headcount is growing. At three employees, DIY is fine. At fifteen, with a mix of local citizens, PRs, and foreigners, DIY becomes genuinely risky.
- You’re already outsourcing your accounts. Having your payroll provider process salaries means the journals hit your management accounts automatically, with no manual reconciliation.
- You’ve had a CPF mistake before. Once you’ve paid the interest or the penalty, the cost calculation changes.
When keeping payroll in-house makes sense
- You have a dedicated, capable HR or admin person who actively tracks payroll compliance
- Your payroll is simple and static: five employees, same salary every month, no foreigners, no commissions
- You want direct control over payroll data and timing
What to ask a payroll provider before signing up
- What happens when you make a mistake? How do you handle corrections and any penalties from your errors?
- What regulatory changes are you responsible for tracking vs us?
- How are payroll inputs submitted each month?
- Is IR8A included or an add-on?
- Who is the actual person handling our payroll?
Bundling payroll with accounting and corporate secretary
Many Singapore SMEs use a single corporate services firm for accounting, company secretary, and payroll. Salary costs flow directly into management accounts without manual journal entries. IR8A and financial year-end information come from the same dataset. Compliance deadlines across all three services are tracked by one provider. And it’s typically cheaper than sourcing each service separately.
