Per Diem Allowance

Per diem allowance refers to the daily allowance given to employees on overseas trips (i.e. either out of Singapore or into Singapore) for business purposes.

This payment is usually made when employees travel overseas to meet clients, or to attend training and conferences. The allowance is meant to cover certain living expenses incurred overseas such as the cost of meals, transport and other incidental items like laundry.

The following payments do not fall under per diem allowance and are not taxable :

  • Overseas accommodation
  • Overseas airport transfer
  • Travelling expenses between cities for business purpose
  • Entertainment expenses for business purpose

Tax Treatment for Per Diem Allowance

Per diem allowance is taxable unless it can be proved that it is subsistence in nature. As the standard of living differs across countries/regions, the subsistence level varies from country to country/region to region.

Acceptable Rates for Travelling Out of Singapore for Business Purpose

In the past, companies had to submit the rates for IRAS' approval. Taking into account the feedback from employers. IRAS has decided to publish the acceptable rates by countries/regions.

The tax treatment for per diem allowance paid in 2005 and subsequent years is as follows:

 Allowance not exceeding acceptable rateAllowance more than acceptable rate

Report in Form IR8A?

No

Yes. Report the amount in excess of acceptable rate.

Tax impact on employee

Not taxable

The amount in excess of acceptable rate is taxable.

Where the per diem allowance is less than the acceptable rate paid for a trip, it cannot be used to offset against the taxable amount arising from other trips.

Example 1: Allowance Below Acceptable Rate

The acceptable rate for Germany is $108 per day for 2021.

Kaisha Ltd paid Mr C $100 per day when he went to Germany for business meetings. Since the per diem allowance of $100 is less than the acceptable rate of $108, there is no taxable benefit. Kaisha Ltd does not have to declare the allowance in the Form IR8A.

Example 2: Allowance Above Acceptable Rate

The acceptable rate for Germany is $108 per day for 2021.

Taka Ltd paid Mr D per diem allowance of $150 per day when he went to Germany to meet clients. Mr D received $900 for the six days that he was in Germany.

Amount in excess of acceptable rate per day = $150 - $108 = $42

Taxable amount and to be reported in Form IR8A = $42 x 6 = $252

Acceptable Rates for Travelling Into Singapore for Business Purpose (Effective YA 2017)

The tax treatment of per diem allowance paid for business trips into Singapore on or after 1 January 2016 is as follows:

 Allowance not exceeding acceptable rateAllowance more than acceptable rate 
Report in Form IR8A?NoYes. Report the amount in excess of acceptable rate.
Tax impact on employeeNot taxable

The amount in excess of acceptable rate is taxable. 

However, if you travel into Singapore for business purpose for 60 days or less in a year, you will be exempted from tax on your earnings here. For more information, please refer to Working for Foreign Employers. 

Annual Review of Acceptable Rates

IRAS reviews the rates yearly based on information from employers and other relevant information. The rates for the following year are published in December every year.

The acceptable rates determined by IRAS are strictly for Income Tax purpose. The rates do not determine the amount of per diem allowance that an employer wishes to pay its employees.

Application for Waiver / Review of Acceptable Rates

The acceptable rates for the following year are published in December so that employers can work out the taxable amount. The rates are applicable for January to December in the following year. Once the rates are published, no changes will be made so that the same rates apply to all employees.

If your company pays a higher per diem allowance than the acceptable rates set by IRAS and you think the higher allowance paid to your employees is justifiable, you can inform IRAS of these rates so that IRAS can consider them when reviewing the acceptable rates for the following year.

How to submit your proposed rates to IRAS:

  1. Email your rates to " taxqueries@iras.gov.sg ".
  2. Attach the report conducted by a consulting firm on the cost of living or other relevant information to support your basis. Proposed rates based on the employee's own experience in the country/region will not be accepted by IRAS.
  3. Declare the amount that is in excess of IRAS acceptable rate in the Form IR8A for the current year.

  • Can an employee claim expenses against the excess portion that will be taxed?

    No. The acceptable rates would have covered expenses which are subsistence in nature.

  • If an employee travels across countries within the same day, what is the rate that should be used to compare against the per diem allowance given?

    Per diem allowance should be a proxy for the actual amount of living expenses that the employee incurs or is likely to incur in the day. The comparison should be reasonable and reflect the consumption pattern of that day.

  • If an employee departs Singapore on 1 Nov and returns on 5 Nov in the same year, what is the number of days that is considered to be "outside of Singapore" for the purpose of computing per diem allowance?

    IRAS will accept the number of days determined by the employer according to its HR policy which is to be applied for all employees concerned, so long as the number of days does not exceed the total length of trip.

    In this case, we would accept the overseas trip as 5 days if this is so determined by the employer.

  • What if a lump sum allowance is paid to cover accommodation, meal, transport expenses and other incidental expenses such as laundry?

    The taxable amount is the lump sum payment less the acceptable rate and non-taxable items. The non-taxable items are:

    • Overseas accommodation
    • Overseas airport transfer
    • Travelling expenses between cities for business purpose
    • Entertainment expenses for business purpose

  • If the per diem allowance is paid in foreign currency, which exchange rate should be used to convert it to Singapore dollars?

    You can use your in-house exchange rate. If you do not have one, you can use exchange rates published by local banks, locally circulated newspapers and reputable news agencies. However the same source must be consistently used.
