Overpaid Salary in Singapore: Recovering It From an Employee, Refunding Excess CPF and Amending IR8A

Short answer: Section 27(1)(f) of the Employment Act lets an employer deduct an overpayment of salary from later pay, and MOM says the full amount can be recovered, outside the 50% cap. Excess CPF paid on the overpayment is refunded by the CPF Board if the employer applies within one year, and a filed Form IR8A must be amended.

A typo in the payroll file, or a leaver paid for the whole month: overpaid salary Singapore employers discover is usually a payroll error, not a dispute. Getting the money back is only half the job. The company also has to correct the CPF paid on the wrong figure and, if the year has closed, the income reported to IRAS. This guide covers what the Employment Act allows, the CPF refund, Form IR8A amendments and the steps to follow.

What counts as an overpayment of salary?

An overpayment is any amount paid to an employee that was not due under the contract for that salary period. Common causes are data-entry errors, a resigned employee left on the payroll, unpaid leave entered after the salary run, or an allowance paid after it should have stopped.

The Employment Act also covers a related item: an unearned employment benefit. Section 27(3) defines an employment benefit as any benefit an employee derives from being employed, other than salary, and gives two examples:

• annual leave taken in excess of the employee’s statutory entitlement under section 88A; and
• a flexible employment benefit, such as an allowance the employee may use at their discretion for purposes set out in the contract.

A salary advance (salary paid early on purpose) and a staff loan are not overpayments; both have their own instalment limits, explained in our guide to salary advances and staff loans. A duplicated expense reimbursement is not salary either; our guide to staff expense claims covers approval controls that catch duplicates.

Overpaid salary in Singapore: can you deduct it from the next payslip?

Yes, for employees covered by the Employment Act. Section 27(1)(f) authorises a deduction for the adjustment of any overpayment of salary, and MOM’s guidance on allowable salary deductions says the employer can recover the full amount.

The rules that frame the deduction:

Recovering the full amount at once is lawful but not always wise. Most employers explain the error in writing, agree a schedule, and show the recovery as a separate line on the itemised payslip.

For work pass holders, MOM’s page states that an employer may increase or make new deductions only with the employee’s written consent and after informing MOM, through WP Online for Work Permit holders, or through the EP eService one month before a salary reduction for Employment Pass and S Pass holders. Check this before the deduction runs. The wider limits on other kinds of deduction are set out in our guide to what an employer may and may not deduct.

What if the employee has already left?

If the overpayment is found before the final salary is paid, it can be deducted from that final salary. The 50% cap does not apply to the last salary due on termination, and overpayment recoveries are outside the cap anyway.

If the employee has already been paid out and left, there is no salary left to deduct from. The company then has to ask for repayment:

1. Write to the former employee with the calculation: what was paid, what was due and the net excess received, with bank details for repayment.
2. Offer instalments if the amount is large, and get the repayment plan signed.
3. If the person refuses to repay, the company would have to bring a civil claim to recover the money. Before taking that step, speak to a lawyer about the claim and the costs of pursuing it, which may exceed a small overpayment.

Do not hold back other money due to a departing employee to cover an overpayment the Act does not let you deduct. Sections 22 and 23 set when the final salary must be paid, and under section 34 a failure to pay on time is an offence punishable, for a first offence, by a fine of S$3,000 to S$15,000, imprisonment of up to 6 months, or both.

What happens to the CPF paid on the overpaid salary?

CPF paid on wages that were not actually payable is an overpaid contribution. The employer applies to the CPF Board for a refund, but must first return the employee’s share of that excess to the employee.

The CPF Board’s page on applying for a refund of CPF contributions sets the conditions:

• The request must be made immediately and no later than one year from the date of payment of the contributions, shown in the “PAYMENTS RECEIVED ON” field of the record of payment.
• The whole refund, employer’s and employee’s shares, is paid to the employer, and the employer is responsible for refunding the employee’s share directly to the employee before applying.
• The employer must tell the affected employee that a refund is being applied for and resolve any dispute first.
• The application must declare the employee’s actual wages for the month, not a figure worked back from the refund.
• The refund is made from the funds available in the employee’s CPF accounts.

An employee whose share was not returned can write to the CPF Board, which will contact the employer.

Worked example

Example (hypothetical): an employee aged 30 has a contractual salary of S$4,000. In March 2026 payroll keys in S$5,000. At the CPF rates for employees aged 55 and below (17% employer, 20% employee, 37% in total on monthly wages above S$750):

The employee received S$800 more cash than they should have; the other S$200 of the S$1,000 gross overpayment went into their CPF account. The company recovers the S$1,000 overpayment of salary, refunds the employee’s S$200 share to the employee, then applies for the S$370 refund declaring March wages as S$4,000. If both lines go through the same payslip, the net deduction is S$800, which matches what the employee actually received. The S$370 total excess matches the CPF Board’s own example of a S$4,000 salary wrongly declared as S$5,000.

Do not reduce April’s declared wages to recover March’s error: the CPF Board asks employers to declare actual wages for each contribution month, so March is corrected through the refund application. The CPF Board’s page on declaring accurate wage information warns that knowingly giving false information is an offence, with a fine of up to S$5,000, imprisonment of up to 6 months, or both, for a first offence.

Do you need to amend Form IR8A?

If the overpaid salary was reported to IRAS in a submitted Form IR8A, yes. IRAS’s explanatory notes ask employers to report the salary due for the year, and IRAS cannot edit or delete submitted records itself, so the employer must file a correction.

For employers under the Auto-Inclusion Scheme, IRAS’s amendment guidance offers two methods through “Submit Employment Income Records” on myTax Portal:

Points from IRAS’s amendment user guide:

• Amendments can be submitted electronically for up to 4 back years. For an over-declared amount older than that, IRAS asks the employer to email the affected employee details using its Excel template.
• Employers not in the Auto-Inclusion Scheme prepare a new Form IR8A marked “Revised” (or “Additional”) and give it to the employee.

If the error is found before the 1 March filing, report the correct salary in the first place. Under section 95 of the Income Tax Act, giving incorrect information affecting another person’s tax is an offence. Our guide to Form IR8A and the Auto-Inclusion Scheme covers the annual filing itself.

What are the steps to recover overpaid salary?

Work through the correction in this order, so the payslip, CPF record and IRAS record all end up with the same figure.

1. Confirm the error: compare the contract, the approved payroll and the bank payment, and work out the gross and net overpayment for each affected month.
2. Calculate the CPF effect: the excess employee and employer shares for each month.
3. Write to the employee with the calculation and the proposed recovery, and agree a schedule if needed. For work pass holders, complete MOM’s consent and notification steps first.
4. Run the recovery through payroll as a separate, labelled deduction under section 27(1)(f), or collect it directly if the employee has left.
5. Refund the employee’s share of the excess CPF to the employee, then apply to the CPF Board for the refund within one year of the payment date, declaring actual wages.
6. If Form IR8A has been filed for that year, submit a revision or amendment on myTax Portal.
7. Correct the ledger so salary, CPF and the amount due from the employee agree, and add a second check on new salary figures and leavers before each payroll run.

What mistakes should employers avoid?

The usual mistakes are recovering the gross amount without returning the employee’s CPF share, missing the one-year CPF refund window, and forgetting the IR8A, which leaves the employee taxed on income they have repaid. If the employee says the sum was a bonus or a promised increase, resolve that first; the CPF Board requires disputes to be settled before a refund application.

Frequently asked questions

Do we need the employee’s consent to deduct overpaid salary?

For employees covered by the Employment Act, section 27(1)(f) authorises the deduction without the written consent needed for consent-based deductions. Telling the employee first and agreeing a schedule avoids disputes. For work pass holders, MOM requires written consent and notice to MOM before new deductions.

Can we recover the whole overpayment in one month?

MOM says the full amount can be recovered, and overpayment recoveries are outside the 50% cap. Spreading a large recovery over a few months by agreement is usually more practical.

What if we only discover the overpayment 18 months later?

The salary can still be recovered, but the CPF Board’s refund route requires the application no later than one year from the date the contributions were paid. Contact the CPF Board about contributions outside that window.

The employee took more annual leave than they were entitled to before resigning. Is that an overpayment?

Annual leave taken beyond the statutory entitlement under section 88A is an unearned employment benefit under section 27(3), and section 27(1)(f) allows its recovery by deduction.
