Staff Expense Claims in Singapore: Reimbursements, Transport and Mileage Allowances, and How IRAS, CPF and GST Treat Them

Short answer: A reimbursement of an actual business expense, backed by a receipt and not exceeding the amount spent, is generally not taxable for the employee and is not wages for CPF. A fixed allowance, such as a monthly transport allowance, is taxable and attracts CPF. GST on staff claims is claimable only with proper invoices and outside the blocked categories.

Most SMEs set up staff expense claims Singapore style in a hurry: an employee pays for a client lunch or a ride to a meeting, hands in a receipt and is paid back with the next salary. That works until IRAS, the CPF Board or an auditor asks why a “transport claim” is the same S$300 every month. This guide covers the rules an expense claims policy must follow, transport and mileage, payroll and Form IR8A, GST on claims, and the records to keep.

What is the difference between a reimbursement and an allowance?

A reimbursement repays an employee for a specific business expense already incurred, against evidence, for no more than was spent. An allowance is paid whether or not the money is spent, usually at a fixed rate.

• Income tax. IRAS’s starting point is that all gains and profits from employment are taxable unless exempt or covered by an administrative concession. Repaying an employee for doing the company’s work leaves them no better off, and IRAS lists reimbursements for official duties as not taxable. An allowance is a gain and is taxable.
• Personal items. IRAS states that reimbursing an item that is not exempt or covered by a concession is taxable. Its example is holiday expenses: calling a holiday a “claim” does not make it a business expense.
• CPF. The CPF Board defines wages as remuneration in money, including bonus, due in respect of employment. Allowances are wages. Reimbursements incurred on behalf of the employer for official purposes are not, provided the amount does not exceed what was spent.

The payslip label does not decide the treatment. A “reimbursement” paid as a flat monthly sum with no receipts is an allowance, and payroll should treat it as one.

How are transport claims and mileage allowances treated?

Transport for official duties reimbursed at cost is not taxable and does not attract CPF. A fixed monthly transport allowance is taxable and attracts CPF. Mileage on an employee’s own car sits in between.

IRAS’s guidance on transport benefits sets out the employee’s position:

• Trips to discharge official duties, such as office to client or client to client, reimbursed at cost: not taxable.
• Home to the airport for an overseas business trip, or home to a business venue for business: reimbursements, and per-trip allowances for actual trips, are not taxable.
• Overtime transport: not taxable if it is for ad hoc work beyond official hours and the policy is generally available to all employees (or applies only to lower-level staff). Ordinary commuting is the employee’s own cost.

For a private car, reimbursed private mileage is taxable, but mileage on four kinds of trip is not: office to external business meetings, home to the airport for overseas business trips, home to external business meetings, and home to office when working overtime. There is no prescribed mileage rate; it depends on company policy but should be reasonable.

The company’s side differs. IRAS’s business expenses guidance allows no deduction for motor vehicle expenses on private cars, whether paid directly or reimbursed, even if the car is used for business, and lists mileage on private cars as non-deductible. Reimbursed taxi or private hire rides for official duties remain deductible, and so does a transport allowance, although the employee is taxed on it. Our guide to company car tax and S-plated car rules explains the car restriction.

Staff expense claims Singapore: how is each claim type treated?

The table summarises common claims for a GST-registered company, based on IRAS and CPF Board guidance, for expenses incurred in Singapore.

Overseas trips and per diems have their own rules, set out in our guide to the per diem allowance and business travel claims. Spending put on a company card instead of claimed back is covered in our company credit card guide.

When does a staff claim attract CPF contributions?

CPF is payable on wages, and an allowance is wages. A reimbursement escapes CPF only if it repays an expense incurred for official purposes and does not exceed what was spent.

The CPF Board’s wages page and its list of allowances give these examples:

• Transport subsidies attract CPF. Reimbursements for travel in the line of official duty, travel between home and workplace beyond normal working hours, and travel to a place of assignment that is not the normal workplace do not.
• Cash for an employee’s personal car costs (petrol, parking, ERP, road tax, insurance, servicing) attracts CPF.
• A handphone allowance attracts CPF; reimbursing handphone expenses necessarily incurred for official purposes does not.
• Reimbursed client entertainment does not attract CPF; reimbursed holiday expenses do.

An allowance given for the month’s work and payable by the 14th of the following month is Ordinary Wages, so it goes into that month’s CPF computation.

Can the company claim GST on staff expense claims?

Yes, if the company is GST-registered and every input tax condition is met. The usual problems are invoices in the employee’s name and expenses the GST rules block.

IRAS’s conditions include that the goods or services are supplied to the company for its business, and that local purchases are supported by a valid tax invoice addressed to the company, or a simplified tax invoice for purchases of S$1,000 or less including GST. Claim the input tax in the accounting period matching the invoice date.

Many receipts show the employee’s name. IRAS’s page on expenses incurred by employees on behalf of the company says such claims are allowed only if the employee acted as the company’s agent, shown for example by evidence of the reimbursement and booking the bill as a business expense. GST on any private part of the bill is not claimable.

Regulations 26 and 27 of the GST (General) Regulations block input tax on benefits for staff’s family members; costs and running expenses of motor cars, including petrol, parking and ERP; sports and recreation club subscription fees; staff medical expenses unless an exception applies; and betting or gaming transactions. Since 1 April 2022, GST on pay-per-trip chauffeured private hire rides can be claimed. For client entertainment above S$1,000, IRAS accepts a receipt with simplified tax invoice details as a concession, if you keep payment evidence and record who was entertained and why. Meals for your own team count as employee benefits, not entertainment. See our guide to input tax claims under Singapore GST.

What goes into Form IR8A for expense claims?

Taxable allowances are reported under “d) 1. Allowances” in Form IR8A. Non-taxable reimbursements of official expenses are not reported.

IRAS’s explanatory notes state that allowances are taxable unless exempt or covered by a concession. The form goes to employees by 1 March of the following year, or AIS employers submit the data to IRAS by the same date. Under section 94 of the Income Tax Act, missing the deadline can lead on conviction to a fine of up to S$5,000, and section 95 penalises incorrect information about another person’s tax. Tag each claim type in payroll as “reimbursement” or “allowance” so year-end figures come out right. Where the company provides a car, reimbursed running costs belong in the Appendix 8A car benefit, not in claims. If a director’s personal costs have gone through claims, see our guide on when the company has paid a director’s personal expenses.

What should an SME expense claims policy include?

A short written policy, approved by the directors, stating what can be claimed, at what rate, with what evidence and who approves it. Use this sample checklist as a starting point.

How should claims be approved and recorded?

Every claim should follow the same route, so each payment can be traced from receipt to bank and ledger.

1. The employee submits the claim with the receipt, date, amount and business purpose, plus a trip log for mileage.
2. The line manager confirms it was for company work and within policy. Nobody approves their own claim; a director’s claims go to another director.
3. Finance checks the arithmetic, rate, evidence and duplicates, and decides whether GST is claimable.
4. Finance codes each line, separates any private element, and marks non-deductible items such as private car mileage for the tax computation.
5. The claim is paid as a non-wage item with payroll or by transfer, and the payment reference is recorded.
6. The claim form, receipts, approval and payment evidence are filed together.

IRAS requires records to be kept for at least 5 years from the relevant Year of Assessment. A 2026 claim in a company with a December year end falls in Year of Assessment 2027, so keep it until at least 31 December 2032.

Frequently asked questions

Is a fixed monthly transport claim with no receipts a reimbursement?

No. A flat sum paid regardless of spending is an allowance. IRAS taxes a fixed monthly transport allowance, and the CPF Board treats transport subsidies as wages.

Can we pay staff mileage for using their own car?

Yes. Mileage for the business trips IRAS lists is not taxable for the employee at a reasonable rate. The company cannot deduct it or claim GST on it.

Can the company claim GST on a receipt in the employee’s name?

Only if it can show the employee acted as its agent, for example through reimbursement evidence and booking the bill as a business expense, and the other conditions are met.

Are overtime taxi fares taxable?

Not if they are for ad hoc work beyond official hours and the policy is generally available to all employees.
