Singapore Corporate Tax and Withholding Tax 2026 Guide

What is the corporate tax rate in Singapore for 2026?

The rate is 17%. However, here's the good news: companies can claim a 40% tax rebate, capped at S$30,000. Furthermore, the minimum benefit is S$1,500 for qualifying firms.

What is the withholding tax rate?

It depends on the payment type:

When must you file?

File by the 15th of the second month after payment. For example: Pay on January 10 → File by March 15.

Withholding tax (WHT) is straightforward: when you pay a non-resident, you must hold back tax at the source. In other words, the tax burden falls on the payer, not the recipient. If you get it wrong, IRAS comes after you — not the overseas vendor.

For a dedicated deep-dive into this topic, see our full Singapore withholding tax guide.

Who is a non-resident?

Here's what you withhold based on payment type:

Important: These are standard rates. However, if the recipient lives in a country with a Double Taxation Agreement (DTA) with Singapore, the rate may drop significantly. Singapore has over 100 active DTAs.

Many foreign entrepreneurs and business owners make preventable withholding tax mistakes. Here are the five most common errors:

First, many companies forget to withhold tax altogether. They pay an overseas vendor and assume no tax applies. Subsequently, IRAS audits them and demands payment plus penalties.

Solution: Always check if the recipient is a non-resident. If yes, withhold tax.

Second, companies often apply the wrong rate. For instance, they withhold 17% on royalties when the rate is 10%. As a result, they overpay IRAS and lose money.

Solution: Verify the payment type and apply the correct rate. When in doubt, contact IRAS or our corporate tax services team.

Third, many businesses miss the 15th of the second month deadline. Consequently, they face immediate penalties and audit flags.

Solution: Mark your calendar. File Form S45 by the 15th of the second month after payment.

Fourth, companies don't obtain a Certificate of Residence when they should. Consequently, they miss out on lower DTA rates and overpay tax.

Solution: If the vendor is from a DTA country, request a COR. See the next section for the process.

Fifth, many business owners confuse withholding tax with GST. Consequently, they either double-withhold or fail to withhold when they should.

Solution: Understand that withholding tax and GST are separate obligations. For more details, see our Singapore GST services page.

This is confusing. The answer depends on what you buy.

Off-the-Shelf Software (No Tax)

You buy standard software (like a boxed product) for your own use. This is a goods purchase. Therefore, no withholding tax applies.

Cloud Software & Licenses (10% Tax)

However, if you pay for a cloud service or software license, IRAS treats this as a royalty. Because you're paying for the right to use intellectual property, you must withhold 10% tax from non-resident vendors. For more on how IRAS classifies digital payments, see the IRAS e-Tax guide on royalties.

This matters for service fees. Here's the key distinction:

Services Done Outside Singapore (May Skip Tax)

The consultant works entirely outside Singapore. They code from India or consult via Zoom from the UK. The income may not be Singapore-sourced. You might skip withholding or file a "nil" return.

Services Done in Singapore (17% Tax)

However, if the work happens in Singapore, 17% withholding tax applies. For further guidance, our Singapore corporate tax services team can advise on the correct treatment.

Yes, but follow the rules. Singapore has over 100 tax treaties. To use a lower rate (for example, 5% instead of 10% for royalties), get a Certificate of Residence (COR) from the vendor's tax office first.

Don't assume a lower rate without proof. This triggers audits. For the full list of Singapore's active DTAs, see the IRAS list of Double Taxation Agreements.

No. Dormant firms are not auto-exempt. You must apply to IRAS for exemption. Without approval, file a dormant return. Failing to file means penalties. For full annual compliance obligations, see our Singapore corporate compliance 2026 guide.

If you don't have a COR, you must withhold at the standard rate. For example, withhold 10% on royalties instead of the lower treaty rate. Subsequently, your vendor can claim a foreign tax credit in their home country.

Generally, no. Withholding tax is not the same as GST input tax. However, you may be able to claim a foreign tax credit in certain circumstances. Consult our corporate tax services team for your specific situation.
