Singapore payroll has three compliance layers that interact with each other: Central Provident Fund (CPF) contributions, IRAS statutory filings, and MOM Employment Act rules on overtime, AWS, and leave encashment. Get any one of them wrong, and you face MOM penalties, CPB Board surcharges, or IRAS late-filing fees. Our team has spoken with Singapore SMEs who paid more in CPF late interest than they saved by doing payroll manually. HR payroll software Singapore platforms exist precisely to remove that risk. This guide covers what the software must do, what it costs, and how to evaluate vendors.
Key Takeaways
– CPF contributions have four age brackets: Rates differ for employees below 55, 55 to 60, 60 to 65, and above 65, and change when the employee crosses a birthday mid-year (Source: CPF Board, https://www.cpf.gov.sg/employer/employer-obligations/how-much-cpf-contributions-to-pay).
– IRAS IR8A deadline is 1 March: All employers must submit IR8A for each employee annually under the Auto-Inclusion Scheme (Source: IRAS, https://www.iras.gov.sg/taxes/individual-income-tax/employers/auto-inclusion-scheme).
– Skills Development Levy (SDL) applies to all employees: SDL is 0.25% of the first SGD 4,500 of gross monthly wages, with a minimum of SGD 2 per month (Source: SkillsFuture Singapore, https://www.skillsfuture.gov.sg/sdl).
– Annual Wage Supplement (AWS) is contractual, not statutory: AWS (“13th month bonus”) is only compulsory if stated in the employment contract or collective agreement (Source: Ministry of Manpower, https://www.mom.gov.sg/employment-practices/salary/annual-wage-supplement).
– PSG grant covers up to 50%: Pre-approved HR payroll software vendors qualify under the Productivity Solutions Grant (Source: Enterprise Singapore, https://www.enterprisesg.gov.sg/financial-support/productivity-solutions-grant).
What Does HR Payroll Software Do in Singapore?
HR payroll software Singapore automates the calculation, disbursement, and statutory reporting of employee compensation, including CPF, IRAS, SDL, and MOM-mandated pay components. A Singapore-built platform handles these as built-in rules, not manual configurations.
The payroll cycle in Singapore has more moving parts than most employers expect. Each month, you calculate gross pay, deduct CPF (employee share), add employer CPF, calculate SDL, check overtime for Part IV employees, process leave encashment for departing staff, and generate a GIRO file for bank payment. A good payroll system automates every step in that sequence. A generic international system often handles only basic gross-to-net pay, leaving the Singapore-specific steps to your HR team.
“Singapore payroll is not difficult if your software knows the CPF age brackets. It becomes very difficult when it does not.”
What Singapore Compliance Must HR Payroll Software Handle?
Singapore HR payroll software must cover four statutory requirements: CPF contributions, IRAS AIS e-submission, SDL payment, and MOM payslip rules. Each has its own calculation logic and filing deadline.
Compliance Item | Frequency | Authority | Penalty for Non-Compliance
CPF contribution | Monthly | CPF Board | 1.5% per month late interest + composition fines
IR8A / AIS filing | Annual (by 1 Mar) | IRAS | Late filing penalties
SDL payment | Monthly | SkillsFuture SG | Arrears + interest2Itemised payslip | Every pay period | MOM | Up to SGD 1,000 per offence
MOM requires employers to issue itemised payslips within three days of payment to all employees on an Employment Act contract (Source: Ministry of Manpower, https://www.mom.gov.sg/employment-practices/employment-rights-conditions/salary/itemised-payslips). Most Singapore payroll platforms generate payslips automatically as part of the payroll run.
How Does CPF Auto-Calculation Work in Payroll Software?
CPF auto-calculation works by reading the employee’s date of birth, ordinary wages, and additional wages each month, then applying the CPF Board’s published rate table to split contributions between employer and employee.
The rates differ by age bracket:
Employee Age | Employer CPF Rate | Employee CPF Rate
Below 55 | 17% | 20%
55 to 60 | 15% | 16%
60 to 65 | 11.5% | 10.5%
Above 65 | 9% | 7.5%
Source: CPF Board, https://www.cpf.gov.sg/employer/employer-obligations/how-much-cpf-contributions-to-pay (rates as of 2026; verify current rates at time of publication).
When an employee’s birthday falls mid-month, payroll software must apply the old rate for the portion of the month before the birthday and the new rate after. Not all systems handle this correctly. Verify this capability in your demo before signing.
What Does HR Payroll Software Cost in Singapore?
Most Singapore HR payroll software vendors price their full-feature tiers (CPF, IRAS, SDL, payslip generation) in the SGD 4 to SGD 12 per employee per month range, based on publicly listed competitor pricing. Entry-level tiers covering payroll only tend to start lower.
The real cost is higher than the per-seat price suggests. Many vendors price the core payroll module cheaply, then charge separately for IRAS AIS integration, biometric attendance sync, and multi-entity support. When evaluating HR software Singapore (https://tipsoi.ai/blog/hr-software-singapore-complete-guide) options, ask each vendor for a fully-loaded quote covering every module your Singapore operations require.
The Productivity Solutions Grant (PSG) reduces costs by up to 50% for qualifying Singapore companies (Source: Enterprise Singapore, https://www.enterprisesg.gov.sg/financial-support/productivity-solutions-grant). For Tipsoi’s pricing, request a quote.
How Does Payroll Software Connect to Attendance and Leave?
The most accurate payroll runs in Singapore come from systems where payroll, leave, and attendance share a single database rather than importing data between separate tools. When employee attendance tracking Singapore (https://tipsoi.ai/blog/employee-attendance-tracking-singapore) data lives in the same system as payroll, overtime is calculated automatically from actual clock records. When the leave management system Singapore (https://tipsoi.ai/blog/leave-management-system-singapore) data is connected, leave encashment and unpaid leave deductions happen without manual entry.
Disconnected systems (separate attendance and payroll apps linked by CSV exports) introduce errors at every sync point. We recommend integrated platforms for this reason.
Frequently Asked Questions
What is CPF, and how is it calculated in payroll software?
CPF (Central Provident Fund) is Singapore’s mandatory social security savings system, funded by contributions from both employer and employee each month. Payroll software calculates CPF by reading the employee’s age bracket and applying the published contribution rates to ordinary and additional wages (Source: CPF Board, https://www.cpf.gov.sg/employer/employer-obligations/how-much-cpf-contributions-to-pay). Total monthly CPF (employer + employee combined) ranges from 16.5% to 37% of ordinary wages, depending on the employee’s age.
Does HR payroll software handle IRAS IR8A filing?
Yes, Singapore payroll software that supports the Auto-Inclusion Scheme (AIS) submits IR8A data directly to IRAS electronically. Employers enrolled in AIS do not need to issue paper IR8A forms to employees (Source: IRAS, https://www.iras.gov.sg/taxes/individual-income-tax/employers/auto-inclusion-scheme). AIS enrolment is mandatory for employers with six or more employees. Verify that your payroll vendor is on the IRAS AIS-approved software list.
What is the Skills Development Levy, and does payroll software handle it?
The Skills Development Levy (SDL) is a mandatory monthly payment of 0.25% of gross wages (first SGD 4,500), with a minimum of SGD 2 per employee per month (Source: SkillsFuture Singapore, https://www.skillsfuture.gov.sg/sdl). Most Singapore payroll platforms calculate SDL automatically as part of the monthly payroll run and include it in the CPF submission file. Confirm this in your vendor demo.
How does payroll software handle mid-month salary changes?
Good Singapore payroll software supports pro-rata salary calculations for mid-month hires, resignations, or salary changes. The system calculates the exact number of working days in each rate period, applies the correct CPF rate, and generates a single payslip showing the breakdown. This is a standard feature in most Singapore platforms, but worth testing with a sample scenario during your evaluation.
Can HR payroll software generate GIRO payment files for Singapore banks?
Yes, most Singapore HR payroll software generates a bank-format GIRO file (also called an ACH file) compatible with DBS, OCBC, UOB, and other local banks. You upload this file to your bank’s portal to process salary payments in bulk. This removes the need to manually enter each employee’s payment in Internet Banking. Confirm that your vendor supports your specific bank’s file format.
Conclusion
Singapore payroll has a narrow margin for error. CPF late interest, MOM payslip violations, and IRAS penalties can each outweigh the cost of the software you are trying to save money on. A proper HR payroll software Singapore platform handles CPF age-bracket rates, IRAS AIS filing, SDL, itemised payslips, and GIRO file generation as built-in defaults. Evaluate on those five criteria first, then compare pricing and PSG eligibility. The right platform turns a two-day payroll cycle into a two-hour review.
