- Salary to a Citizen or PR employee-director attracts CPF (37% total for under-55s, on Ordinary Wages up to the S$8,000 monthly ceiling now in effect) and is deductible to the company.
- Director’s fees and dividends carry no CPF. One-tier dividends are tax-exempt to the shareholder, but must come from distributable profits with proper approval.
- Most owner-directors combine a modest salary with dividends to balance CPF, personal tax, and cash flow.
Choosing between in-house payroll and payroll outsourcing in Singapore comes down to whether your team can run salary, CPF and IR8A obligations accurately every month without it becoming a second job. In-house keeps everything under your own roof. Outsourcing hands the calculations, filings and deadlines to a provider. Both are valid, and the right answer changes as you hire. This guide gives you an honest framework: when in-house genuinely makes sense, when outsourcing wins, and what each really costs.
The quick answerSmall Singapore companies with simple, fixed salaries and capable internal staff can run payroll in-house. Most growing SMEs outsource once headcount, variable pay, or CPF and IR8A compliance risk make in-house too time-consuming or error-prone. The decision turns on headcount, in-house finance capability and your appetite for compliance risk, rather than cost alone. |
What does running payroll in-house in Singapore actually involve?
Running payroll in-house means your own team owns every step of paying staff, from the monthly salary run to the year-end tax forms. It is recurring, deadline-driven work that sits on top of someone’s day job.
A typical monthly and annual cycle covers:
- Computing salaries, allowances, overtime and any prorated pay
- Calculating and submitting CPF, plus the Skills Development Levy and Self-Help Group contributions (see payroll taxes and CPF for the full breakdown)
- Issuing itemised payslips and keeping the records
- Filing IR8A through the Auto-Inclusion Scheme at year end, and IR21 tax clearance when a foreign employee leaves
- Managing leave, claims and any mid-year changes to headcount
None of this is impossible to do yourself. The question is whether you have the time and the up-to-date knowledge to do it accurately, month after month. For the operational detail, our payroll management best practices guide is a good companion.
What does payroll outsourcing cover, and how does the handover work?
Payroll outsourcing means a third-party provider runs the cycle for you: calculations, statutory filings, payslips and reminders, usually on a cloud platform you can still see into. You approve, they execute.
A full-service provider typically handles monthly pay runs, CPF and levy submissions, itemised payslips, IR8A and AIS filing, IR21 clearance, and deadline reminders. Many run this on software such as Talenox, so you keep visibility without logging in to do the work yourself.
The switch is the part most owners worry about, and it is more routine than it sounds. A provider speaks to your current setup, transfers your employee and pay data, reviews past records for gaps, and runs a first pay cycle in parallel so salaries are never late. If your records are messy, a clean-up step brings them in line before go-live.
From 1 January 2026 the CPF Ordinary Wage ceiling rose to S$8,000 a month and senior-worker rates changed. If you run payroll in-house, audit your contribution settings now so January pay runs are correct.
In-house payroll vs payroll outsourcing Singapore: At a Glance
In-house payroll gives you control but demands ongoing staff time, carries higher error risk, and gets harder to manage as you grow. Outsourcing hands the monthly cycle, CPF, IR8A and IR21 to specialists at a fixed per-employee cost, so compliance risk drops and the workload stays flat regardless of headcount. The trade-off is straightforward: in-house suits small, stable teams with capable internal staff; outsourcing wins once complexity or growth makes the in-house burden outweigh the fee.
Feature / Factor | In-House Payroll | Payroll Process Outsourcing (PPO) |
Setup & Operations | Managed by internal team using software | Fully managed by a third-party provider |
Time Requirement | High, with monthly processing and filings | Low, as processes are automated and supported |
Compliance Handling | Responsibility stays within the company | Managed by specialists, including CPF, IR8A, IR21 |
Error Risk | Higher due to manual work | Lower due to expert handling and automation |
Scalability | Can be difficult as team size increases | Easily scales with business growth |
Cost | Ongoing staff time and software expenses | Fixed per-employee fee (e.g., Sleek charges $300 per employee annually for end-to-end payroll compliance) |
Doing payroll in-house works if your team’s equipped. But for most growing businesses, outsourcing is quicker, safer, and frees up the team’s essential time.
How much does payroll cost: In-house vs outsourcing?
As we dive deeper into the cost factor, in-house payroll rarely shows its true cost on one line. You pay for software, for the staff hours spent each month, and for the risk of an error that triggers a penalty or a correction. Outsourcing converts that into a predictable per-employee fee.
As a benchmark, Sleek’s payroll runs from S$300 per employee per year for end-to-end compliance: payslips, CPF, SDL and SHG, IR8A and AIS filing, and Talenox leave management. In-house software sits lower per head but adds your team’s time on top; for the tooling options see payroll software options.

What are the compliance risks: CPF, IR8A, payslips, and getting it wrong?
The real cost of a payroll mistake is rarely the salary itself; it is the statutory exposure behind it. Singapore’s rules are specific, and the penalties for missing them are real.
CPF is the biggest one. For employees aged 55 and below, the employer contributes 17% and the employee 20%, on Ordinary Wages up to the S$8,000 monthly ceiling. Contributions are due by the 14th of the following month. Senior-worker rates differ, so age bands matter when you run the numbers; how CPF contributions work sets out the detail.
At year end, employers file IR8A to report each employee’s earnings, and those with five or more employees must submit electronically through the Auto-Inclusion Scheme by 1 March. Late filing is an offence, with fines of up to S$1,000 per employee. Our IR8A and year-end reporting guide walks through the form.
Payslips are not optional either. Under the Employment Act, every covered employee must get an itemised payslip with their salary or within three working days of payment. Repeated failures draw an administrative penalty of up to S$400 per breach. Add the Skills Development Levy (0.25% of monthly wages, capped at S$11.25 per employee) and IR21 clearance for departing foreign staff, and the monthly checklist gets long.
When does in-house payroll still make sense?
In-house is the right call more often than outsourcing providers like to admit. If your situation is genuinely simple, keeping payroll in your own hands is cheaper and gives you immediate control.
In-house tends to work when:
- You have a very small headcount, often under five people
- Salaries are fixed, with little overtime, variable pay or commission
- Someone on the team is confident with CPF, IR8A and payslip rules and has the time each month
- All staff are local, so there is no IR21 clearance to manage
If that describes you, good software and a disciplined monthly routine are usually enough. The case to outsource only gets strong once one of those conditions stops being true.
When does outsourcing win, by headcount and complexity?
Outsourcing earns its fee when payroll stops being simple. As you hire, the time and the risk both climb, and a fixed per-employee fee starts to look cheaper than the hours and the exposure.
Outsourcing usually wins when:
- Headcount is growing, and you are hiring regularly
- There is no dedicated payroll or HR person, and the founder or finance lead is doing it on the side
- Pay is complex: variable components, multiple entities, or foreign employees needing IR21 clearance
- A late or wrong CPF or IR8A filing would be a real financial and reputational risk

FAQs: In-house vs payroll outsourcing in Singapore
Is it better to outsource payroll in Singapore?
For most growing businesses, yes. Outsourcing saves time, reduces filing errors and keeps you compliant as you scale. Very small teams with simple, fixed salaries and a capable internal person can keep payroll in-house cost-effectively. The tipping point is usually a mix of headcount, pay complexity and how much a missed deadline would hurt.
How much does it cost to outsource payroll in Singapore?
Full-service outsourcing is typically priced per employee per year; Sleek’s list price is S$300 per employee annually for end-to-end compliance. Basic payroll software can look cheaper per head, often a few dollars per employee a month, but it leaves the work, and the responsibility, with your team. Compare total cost, including staff hours, not just the licence fee.
Is payroll outsourcing compliant with Singapore's regulations?
Yes. A reputable provider handles CPF, SDL and SHG contributions, itemised payslips, and IR8A and AIS filing in line with CPF Board, MOM and IRAS rules. The legal responsibility still sits with you as the employer, which is exactly why accurate, on-time filings matter so much.
Can I switch to a payroll provider mid-year?
Yes, you can switch at any point in the year. A good provider manages the move end to end: contacting your current setup, transferring employee and pay data, and reviewing past records. If your records are incomplete, a reconstruction step cleans them up so your first run is accurate and on time.
Does outsourcing payroll replace my accountant?
No. Payroll covers salaries, CPF and employee tax forms; accounting covers your books, financial statements and corporate tax. They overlap at year’s end but are separate functions. Many SMEs bundle the two with one provider so the data flows cleanly between them.
