Withholding Tax in Singapore: A Complete Guide for Businesses (2026)

Published on: 21 May, 2026

If your Singapore company pays a foreign supplier, overseas consultant, non-resident director, or a licensor of intellectual property, you almost certainly have a withholding tax (WHT) obligation. Withholding tax is one of the most commonly misunderstood — and frequently missed — compliance requirements for Singapore businesses operating across borders. A single overlooked payment can result in penalties, interest, and IRAS audits.

This guide explains everything you need to know: what withholding tax is, which payments are caught, the applicable rates, how to file and pay via myTax Portal, and how to reduce your liability through Singapore’s extensive Double Taxation Agreement (DTA) network.

What Is Withholding Tax?

Withholding tax is a mechanism under Section 45 of the Income Tax Act 1947 (ITA) that requires the payer — not the recipient — to deduct a specified percentage from certain payments made to non-residents, and remit that amount directly to IRAS. The non-resident receives the net payment; the withheld amount is their tax on Singapore-sourced income.

The obligation falls on the Singapore-resident payer. If you fail to withhold and remit, you remain personally liable for the tax that should have been withheld, plus penalties.

Who Is a Non-Resident for Withholding Tax Purposes?

A non-resident company is one that is not incorporated in Singapore and does not exercise central management and control in Singapore. A non-resident individual is someone who is not a Singapore tax resident — broadly, a person who has not been physically present in Singapore for 183 days or more in a calendar year (with some exceptions).

Note: Withholding tax applies based on where the payee is tax-resident, not where the payment is made from. Even if you transfer money offshore from a Singapore bank account to a foreign bank account, WHT may apply if the nature of the payment is caught under Section 45.

Payments Subject to Withholding Tax — and the Applicable Rates

The following table summarises the main payment types and WHT rates under Singapore domestic law. DTA rates (where applicable) may be lower — see below.

Type of Payment	Recipient	WHT Rate
Interest / deemed interest (e.g. on loans)	Non-resident company	15%
Royalties / licence fees (IP, patents, software)	Non-resident company or individual	10%
Technical assistance / management fees / service fees (for services performed in Singapore)	Non-resident company	17% (prevailing corporate tax rate)
Rent on movable property used in Singapore	Non-resident company or individual	15%
Charter fees (ships / aircraft not registered in Singapore)	Non-resident company	Prevailing corporate tax rate
Fees to non-resident professionals (consultants, trainers, coaches, advisers)	Non-resident individual	15% on gross; or 24% on net income if gross-to-net election made
Director’s fees / remuneration	Non-resident director	24%
Fees to non-resident public entertainers (artistes, musicians, sportspeople)	Non-resident individual	10%
Distribution from Real Estate Investment Trust (REIT)	Non-resident individual or company	10% (individuals); 17% (companies)

Important caveat on service fees: WHT only applies to service fees for work physically performed in Singapore. If a foreign consultant works entirely from their home country with no visit to Singapore, WHT does not apply to those service fees. However, where any part of the work is done in Singapore, the entire fee may be caught — take advice if the position is unclear.

Payments NOT Subject to Withholding Tax

Not all payments to non-residents attract WHT. Key exclusions include:

Dividends — Singapore does not impose withholding tax on dividends paid by Singapore companies to non-resident shareholders. This is one of Singapore’s key competitive advantages as a holding location.
Repayment of loan principal — only the interest component attracts WHT, not the capital repayment.
Pure purchase of goods — payments for goods (not services or intellectual property) are not subject to WHT.
Services performed entirely outside Singapore — fees for services rendered wholly outside Singapore are generally not subject to WHT, unless the services are directly connected to Singapore-sourced income.
Bank interest paid by a financial institution — interest paid by approved banks to non-residents is generally exempt.

How to Calculate the Amount to Withhold

The calculation is straightforward in most cases: apply the relevant WHT rate to the gross amount payable before any deduction. The non-resident receives the net amount; you remit the withheld portion to IRAS.

Example: Your Singapore company engages a foreign IP licensor and agrees to pay royalties of S$50,000. The domestic WHT rate is 10%. You withhold S$5,000 and pay the licensor S$45,000. You then file and remit the S$5,000 to IRAS by the due date.

If the payment is “grossed up” (i.e. you contractually agree to bear the WHT on behalf of the non-resident), the calculation is more complex. In this case the WHT is computed on the grossed-up payment amount. Seek advice before agreeing to gross-up clauses.

Filing and Payment: Step-by-Step via myTax Portal

All withholding tax filings are done electronically via myTax Portal using Singpass (for individuals) or Corppass (for companies). There is no paper filing option for most WHT transactions.

Step 1 — Log in to myTax Portal

Navigate to myTax Portal and log in with Corppass on behalf of your company. Ensure the relevant Corppass role (e.g. “Preparer” or “Approver” for Withholding Tax) has been assigned to the person submitting.

Step 2 — Select “Withholding Tax” Under Corporate Tax Services

On the main dashboard, go to Corporate Tax → Withholding Tax. You can file a new return or amend a previously filed one.

Step 3 — Enter Payment Details

You will be required to provide: the non-resident payee’s name and country of residence; the nature of the payment (interest, royalties, service fees, etc.); the gross amount paid; the date of payment; and whether a DTA claim is being made (see below). The portal calculates the tax automatically based on the payment type.

Step 4 — Submit and Receive the S45 Form

Upon submission, the portal generates a Form S45 (the withholding tax statement). Download and retain a copy. You should also provide the non-resident payee with a copy of the Form S45 so they can use it to claim a credit in their home country (where a DTA applies).

Step 5 — Pay the Withheld Amount to IRAS

Payment can be made by GIRO, PayNow, or bank transfer. Payment must be made by the same deadline as the filing.

The WHT Filing and Payment Deadline

This is where many companies fall short. Withholding tax must be filed and paid by the 15th of the second calendar month following the date of payment (or deemed payment) to the non-resident.

Example: You pay a foreign consultant on 10 April 2026. The WHT deadline is 15 June 2026.

The “date of payment” is generally the date the money is credited to the non-resident’s account, or the date the payment is due under the contract — whichever is earlier. If you accrue a liability at year-end (e.g. an unpaid management fee to a foreign parent company), the accrual date may be the deemed payment date.

Special consolidation option: Companies that pay recurring royalties or service fees under a DTA exemption claim may consolidate and file twice a year — on 15 June and 15 December. This option must be specifically elected.

Claiming DTA Relief to Reduce Your WHT Rate

Singapore has concluded over 90 comprehensive Double Taxation Agreements (DTAs). DTA rates for interest, royalties, and service fees are typically lower than domestic rates — sometimes as low as 0% for certain payment types with treaty partners.

To claim DTA relief:

The non-resident payee must be a tax resident of a DTA country — they must provide a valid Certificate of Residence (COR) from their home country tax authority.
The payee must be the beneficial owner of the income (conduit arrangements generally do not qualify).
The DTA rate claim is made at the time of filing the WHT return on myTax Portal — select “Claim under DTA” and specify the applicable treaty.

If you withhold at the domestic rate but later obtain a valid COR, you can apply for a refund of the excess withheld. IRAS allows retrospective claims subject to time limits.

Common Mistakes to Avoid

IRAS has identified several recurring errors that companies make in relation to withholding tax:

Failing to withhold on accrued but unpaid liabilities — many companies only withhold when cash is paid, but the obligation can arise when the liability is accrued in the accounts.
Applying WHT to dividends — Singapore dividends are not subject to WHT. Applying it incorrectly is a common mistake that requires amendment.
Overlooking WHT on software licence fees — payments for the right to use software are royalties and attract WHT at 10%, unless a DTA reduces this.
Not filing on time because a DTA claim is pending — you must still file and pay (at the domestic rate if necessary) by the due date. Apply for a refund separately once you have the COR.
Incorrect payee residency determination — assuming a payment is to a “company” when the ultimate recipient is an individual, or vice versa, can lead to the wrong rate being applied.

Penalties for Late Filing and Non-Payment

IRAS takes WHT compliance seriously. Late payment and non-payment attract automatic penalties under the Income Tax Act:

5% late payment penalty — imposed immediately on the day after the due date on the unpaid amount.
Additional 1% per month — a further 1% penalty for each month the tax remains outstanding (up to a maximum additional penalty of 15%).
Enforcement action — IRAS may issue recovery notices, appoint agents to recover the tax, or commence court proceedings for persistent non-payers.
Voluntary disclosure — if you discover past WHT errors, voluntary disclosure to IRAS before they initiate an audit typically results in significantly reduced penalties. See IRAS’s voluntary disclosure programme for withholding tax.

Withholding Tax for Specific Scenarios

Intercompany Payments to Foreign Parent or Subsidiary

Many Singapore subsidiaries pay management fees, royalties, or interest to their overseas parent companies. These payments are fully subject to WHT under domestic law. The DTA between Singapore and the parent’s country of residence typically reduces the applicable rate — but the COR must be obtained and the WHT return filed on time.

Cloud Software and SaaS Subscriptions

Payments for access to software (whether hosted on-premises or in the cloud) may constitute royalties if the contract grants rights in the underlying intellectual property. If the overseas software provider grants only a limited right to use (no underlying IP rights), the payment may be characterised as a service fee instead. The characterisation depends on the contract — review carefully.

Non-Resident Director Fees

Director’s fees paid to a non-resident director are subject to 24% WHT. The company is required to withhold and remit to IRAS even if the fees are paid overseas. A resident director who subsequently becomes non-resident during the year should have their fees prorated accordingly.

Foreign Freelancers and Consultants

If your company engages a foreign freelancer who performs any part of their work while physically in Singapore (e.g. on a short-term business visit), you may have WHT obligations on the entire fee. Apply the 15% gross rate or the 24% net income rate — the consultant can elect the net income basis if their Singapore-attributable expenses are significant.

Frequently Asked Questions

Do I need to withhold tax on payments to a foreign company that has a Singapore branch?

No. Payments to a Singapore-registered branch of a foreign company are treated as payments to a Singapore tax resident for WHT purposes — the branch pays tax on its Singapore-sourced income through the normal corporate income tax system. WHT does not apply.

What if the non-resident refuses to accept a net payment and insists on receiving the full amount?

You can gross up the payment — i.e. pay the non-resident the full agreed amount and bear the WHT yourself. However, the WHT is then computed on the grossed-up figure, increasing your total cost. Alternatively, you can negotiate the contract price to account for the WHT deduction.

Is WHT applicable if the foreign company has no presence in Singapore at all?

The applicability of WHT depends on the nature of the payment and whether it has a Singapore connection — not simply whether the payee has a physical presence here. Royalties for IP used in Singapore, and interest on loans used to fund Singapore operations, can attract WHT regardless of whether the recipient has any Singapore presence.

Can I deduct the WHT as a business expense?

The company’s own tax liability (i.e. WHT you bear on a grossed-up basis) is generally not deductible. The gross payment amount (before WHT) is deductible as a business expense, provided it satisfies the general deductibility conditions under the Income Tax Act. Seek advice from your accountant.
