How Much Does Payroll Outsourcing Cost in Singapore? (2026 Price Guide)

By Lucas Seah, Founder of Excellence Singapore Group | Last Updated: June 2026

Outsourcing payroll in Singapore typically costs S$10 to S$30 per employee per month, with most providers applying a minimum monthly fee of around S$100 to S$250. A small business of 10 staff commonly pays S$200 to S$400 a month. The exact figure depends on your headcount, pay frequency, and whether year-end IR8A filing is included.

This guide breaks down the 2026 price bands by company size, exactly what the fee buys you, the hidden add-on costs to ask about, and how outsourcing compares with running payroll in-house.

Key Takeaways

• Typical outsourced payroll in Singapore runs S$10 to S$30 per employee per month, and almost every provider sets a minimum monthly fee, so very small teams pay a higher effective rate per head.
• A core fee usually covers the monthly payroll run, itemised payslips, and CPF calculation and e-submission; year-end IR8A or AIS filing and leave administration are sometimes extra.
• Per-employee pricing falls as headcount rises (economies of scale), so the per-head cost for 30 staff is well below the rate for 5 staff.
• Hidden costs to ask about upfront: off-cycle pay runs, IR8A or AIS year-end filing, foreign-worker levy admin, custom reports, and correction reruns.
• Free spreadsheets and general AI tools cannot file CPF or IR8A for you, and a wrong CPF submission is the employer’s legal liability, not the tool’s.

How much does payroll outsourcing cost in Singapore?

For most Singapore SMEs, outsourced payroll costs between S$10 and S$30 per employee per month, layered on top of a minimum monthly fee that usually sits between S$100 and S$250. The minimum fee matters because it sets a floor: a three-person company does not pay only three times the per-head rate, it pays the minimum. As headcount grows, the per-employee rate drops and the minimum stops biting.

Two numbers drive the quote. The first is your headcount. The second is scope: a bare monthly run costs less than a service that also handles leave records, year-end tax forms, and integration with your accounting software. We unpack both below.

In our experience, the figure that surprises SME owners is not the per-employee rate, it is the minimum fee. A founder with five staff often expects to pay around S$50 a month and is caught off guard by a S$150 floor. That floor exists because the core compliance work (CPF submission, payslips, record-keeping) is largely fixed no matter how few people you employ.

What you actually pay for in a payroll fee

A payroll fee is not just running numbers. It bundles several recurring compliance tasks an employer is legally required to complete every month or every year, and a professional payroll service handles them for you. A standard fee usually includes:

• The monthly payroll run: calculating gross-to-net pay, deductions, allowances, and bonuses.
• Itemised payslips, which are mandatory under the Employment Act and must be given with payment or within 3 working days (MOM).
• CPF calculation and e-submission, with employer and employee CPF computed at the correct age-band rates (37% total for employees aged 55 and below, made up of 17% employer and 20% employee) and filed with the CPF Board (CPF).
• The Skills Development Levy (SDL) at 0.25% of monthly wages, a minimum of S$2 and a maximum of S$11.25 per employee, paid alongside CPF (CPF).
• Basic leave tracking and statutory record-keeping.

What is often quoted separately is year-end tax reporting. Employers with 5 or more employees must submit employees’ income information electronically under the Auto-Inclusion Scheme (AIS) by 1 March each year, the IR8A filing (IRAS). Confirm whether this sits in the base fee or is billed once a year, and see our guide to Form IR8A in Singapore for what it involves.

Typical payroll outsourcing cost by company size

The table below shows typical 2026 market ranges by headcount. Treat them as planning figures, not quotes: actual pricing varies by provider and scope. The pattern that holds across the market is economies of scale, where the per-employee rate falls as you add staff.

Headcount	Typical per-employee per month	Typical monthly total	What is usually included
1 to 5 staff	S$20 to S$30	S$100 to S$250 (minimum fee usually applies)	Monthly run, itemised payslips, CPF e-submission
6 to 10 staff	S$18 to S$28	S$180 to S$400	Above plus leave records and year-end IR8A or AIS
11 to 25 staff	S$15 to S$25	S$350 to S$700	Above plus multiple pay cycles and standard reports
26 to 50 staff	S$12 to S$20	S$600 to S$1,200	Above plus a dedicated specialist and software integration

The chart makes the scale effect concrete. A five-person company commonly pays around S$25 per head, while a fifty-person company pays closer to S$15. The work per employee is similar, but the fixed compliance overhead is spread across more people.

Hidden and add-on costs to ask about

The headline per-employee rate rarely tells the whole story. Ask any provider to confirm, in writing, how these are billed:

• Off-cycle or ad-hoc pay runs (a mid-month leaver, or a separate bonus run).
• Year-end IR8A or AIS submission, if it is not in the base fee.
• Foreign-worker levy tracking and Work Pass-related admin.
• Custom or ad-hoc reports beyond the standard payslip and summary.
• Correction reruns when source data (timesheets, claims) arrives late or wrong.
• One-time setup or onboarding to migrate your existing payroll data.

The single most common surprise on a payroll invoice we review for new clients is the correction rerun. If your timesheet data is messy, you pay twice: once for the run, and again to redo it. Clean inputs are the cheapest way to keep a payroll bill low. When you compare providers, look past the headline rate; our guide to the best payroll services in Singapore covers what separates a strong provider from a cheap one.

What makes payroll cost more or less?

Four factors move your quote up or down:

• Headcount: more staff means a lower per-head rate but a higher total.
• Pay frequency: weekly or fortnightly runs cost more than a single monthly run.
• Complexity: variable hours, commissions, shift allowances, and multiple entities all add processing time.
• Integrations: linking payroll to Xero or QuickBooks, or to a leave or HR system, can add a setup or monthly fee but saves manual work later.

A flat-salary team of office staff paid once a month sits at the cheap end. A retail or food-and-beverage operation with hourly staff, variable shifts, and high turnover sits at the expensive end, even at the same headcount. One related point: genuine contractors are not on payroll and do not attract CPF, but misclassifying staff as contractors is a real risk, which we cover in employee vs contractor under MOM guidelines. Many SMEs also bundle payroll with outsourced accounting to lower the combined fee, and the pricing logic mirrors what we cover in our comparison of the best accounting firms in Singapore.

Is it cheaper to outsource payroll or do it in-house?

For most small companies, outsourcing is cheaper once you count the true cost of doing it yourself. In-house payroll is not free: it needs software, the time of a trained staff member, and it carries the risk of penalties if CPF or IR8A is filed late or wrong. A part-time payroll staffer on even S$1,500 a month costs far more than a S$200 outsourced fee for the same 10-person run.

The break-even depends on headcount and how you value your own time. We compare the two paths in detail in our guide to in-house vs outsourced payroll. The short version: below roughly 20 to 30 staff, outsourcing usually wins on total cost and risk; above that, a dedicated in-house function can become viable.

Can I run payroll for free or with AI tools?

You can run the arithmetic for free in a spreadsheet, and you can ask a general AI tool to calculate gross-to-net pay. What neither can do is file your CPF, submit your IR8A, or take legal responsibility when a figure is wrong. CPF must be e-submitted and paid to the CPF Board, and a wrong or late submission is the employer’s liability, not the tool’s.

A free spreadsheet also will not keep up with rate changes. CPF contribution rates and the Ordinary Wage ceiling (S$8,000 a month from 1 January 2026) change by policy, and senior-worker rates rise again in 2027 (CPF Ordinary Wage ceiling). We track those updates in our employer guide to the CPF contribution rate changes from 2026. Software and outsourced providers apply these for you; a static template does not.

Key Takeaway: Outsourced payroll in Singapore is priced on two things, your headcount and your scope, and lands at roughly S$10 to S$30 per employee per month over a minimum fee. The cheapest way to keep that bill low is clean input data and a clear scope, so off-cycle runs and corrections do not stack up. This guide draws on primary government sources: CPF contribution rates and the Ordinary Wage ceiling from the CPF Board, the SDL calculation from CPF, the AIS and IR8A rules from IRAS, and the itemised-payslip rule from MOM.

Frequently Asked Questions

How much does payroll outsourcing cost in Singapore?

Outsourced payroll in Singapore typically costs S$10 to S$30 per employee per month, with most providers setting a minimum monthly fee of around S$100 to S$250. A 10-person company commonly pays S$200 to S$400 a month. The per-employee rate falls as your headcount rises.

What is included in a payroll outsourcing fee?

A standard fee usually covers the monthly payroll run, gross-to-net calculation, itemised payslips, and CPF calculation and e-submission, plus the Skills Development Levy. Year-end IR8A or AIS filing, leave administration, and software integrations are sometimes billed separately, so confirm the scope before you sign.

Is it cheaper to outsource payroll or do it in-house?

For most small companies it is cheaper to outsource. Doing payroll in-house needs software, a trained staff member’s time, and it carries the risk of penalties for late or wrong CPF and IR8A filing. A part-time payroll hire usually costs far more than a S$200 outsourced fee for the same 10-person run. Above roughly 20 to 30 staff, an in-house function can become viable.

Are there hidden costs in payroll outsourcing?

There can be. Common add-ons are off-cycle or ad-hoc pay runs, year-end IR8A or AIS filing, foreign-worker levy admin, custom reports, correction reruns, and one-time setup. Ask any provider to confirm in writing how each item is billed, so the quotes you compare are complete.

How much does payroll cost per employee in Singapore?

Expect roughly S$10 to S$30 per employee per month. Small teams pay at the higher end because a minimum monthly fee applies, while larger teams pay less per head as the fixed compliance overhead spreads across more people. A 5-person firm often pays about S$25 per head, a 50-person firm closer to S$15.

Can I run payroll for free or with AI tools?

You can do the arithmetic in a free spreadsheet or ask a general AI tool to estimate pay, but neither can file your CPF, submit your IR8A, or take legal responsibility for an error. CPF must be e-submitted to the CPF Board, and a wrong or late submission is the employer’s liability. A static template also will not track CPF rate changes such as the S$8,000 Ordinary Wage ceiling from 2026.
