Singapore Corporate Tax: Rebates and Exemptions in 2026

If you're running a business in Singapore, the number everyone quotes is the 17% corporate tax rate. It's also the number that matters least, because almost no profitable company in Singapore actually pays 17% of its chargeable income in tax.

That's not a loophole. It's how the system is designed to work. Every company gets automatic exemptions on its first SGD 200,000 or so of chargeable income, and for YA 2026 specifically, there's also a rebate on top of that, one that Singapore's government increased partway through the year to help companies manage rising costs. Between the two, a company with SGD 200,000 in chargeable income pays SGD 8,375 in tax this year, not the SGD 34,000 the headline rate implies.

In this guide, we'll walk you through how the YA 2026 corporate income tax rebate works, including the mid-year increase; how the Start-Up Tax Exemption (SUTE) and Partial Tax Exemption (PTE) reduce your taxable income every year, not just this one; the difference between an exemption (which reduces the income you're taxed on) and a rebate (which reduces the tax bill itself); and a full worked example showing exactly how the numbers stack together.

What Are Corporate Tax Rebates & Tax Exemptions?

Singapore gives companies two different tools to reduce corporate tax, and they work in different ways.

A tax exemption reduces the income you're taxed on. You still apply the 17% rate, just to a smaller number, and it applies every single year for as long as you qualify. A tax rebate reduces the tax bill itself, after it's already been calculated, and it's usually a one-off or time-limited measure announced in a specific Budget.

That distinction matters because it tells you which relief you can count on long-term. SUTE and PTE aren't going anywhere. The current YA 2026 rebate expires at the end of this assessment year, and Parliament decides fresh whether to renew anything similar for YA 2027.

Here's a quick overview:

Corporate Income Tax Rebate for YA 2026

The YA 2026 corporate income tax rebate has a two-stage story worth understanding, because the number you'll see quoted depends on when the source was written.

As announced in Budget 2026, the rebate started at 40% of tax payable, capped at SGD 30,000 combined with the cash grant. Partway through the year, IRAS enhanced it: to help companies manage cashflow pressure from rising costs, the rebate was raised to 50% of tax payable, the cash grant was raised to SGD 2,000, and the combined cap rose to SGD 40,000. That's the version that applies now, and it's the one this guide uses.

The enhanced YA 2026 rebate works like this:

• 50% reduction on tax payable, capped at SGD 40,000 combined with the cash grant below
• An additional SGD 2,000 Corporate Income Tax (CIT) Rebate Cash Grant for companies with at least one local employee who made CPF contributions in 2025, excluding shareholders who are also directors of the company (disbursed directly to your company on a date set by the authorities)

Here's the part that's easy to get wrong: the 50% rebate itself is granted to every taxpaying company in Singapore, resident or not, whether or not you employ anyone locally. The local-employee condition only gates the extra SGD 2,000 cash grant, not the base rebate. If you have no local employees, you still get the 50% rebate on your tax payable (capped at SGD 40,000), but you just don't get the additional cash grant.

For companies that do qualify for the cash grant, the two benefits interact rather than simply stack: if your calculated CIT Rebate is SGD 2,000 or less, you don't receive a separate rebate on top of the grant. If your calculated rebate is more than SGD 2,000, you receive the rebate (capped at SGD 40,000) minus the SGD 2,000 you're already getting as a grant. Either way, the SGD 40,000 cap applies to the combined value of both benefits together, not to each one separately.

The rebate applies automatically. You won't need to submit a separate application: it's applied when you file your Estimated Chargeable Income (ECI) or Form C / Form C-S / Form C-S (Lite) with the Inland Revenue Authority of Singapore (IRAS).

Corporate Tax Exemptions

Corporate tax exemptions are permanent features of Singapore's tax system, not one-off measures tied to a single Budget. Unlike the YA 2026 rebate above, the Start-Up Tax Exemption (SUTE) and Partial Tax Exemption (PTE) apply every year, for every eligible company, regardless of what happens in future Budgets.

The sections below explain how each works.

Start-Up Tax Exemption (SUTE)

The Start-Up Tax Exemption (SUTE) is for newly incorporated companies in their first three Years of Assessment. Instead of taxing all of your chargeable income at 17%, a large portion of it isn't taxed at all:

• 75% of the first SGD 100,000 of chargeable income is exempt from tax
• 50% of the next SGD 100,000 of chargeable income is also exempt

Together, that's up to SGD 125,000 of chargeable income exempted from tax each year, confirmed directly on IRAS's own rate table. To be precise about what that actually saves you: it's SGD 125,000 of income that never gets taxed, not SGD 125,000 knocked off your tax bill. At the 17% rate, exempting SGD 125,000 of income saves you up to SGD 21,250 in tax that you would otherwise have paid, on top of whatever the remaining chargeable income is taxed at.

After your first three Years of Assessment, once you no longer qualify for SUTE, you move to the Partial Tax Exemption (PTE) instead.

Partial Tax Exemption (PTE)

The Partial Tax Exemption (PTE) is the ongoing relief for companies that are no longer eligible for SUTE, or that were never eligible in the first place.

It works the same way as SUTE, just with smaller thresholds:

• 75% of the first SGD 10,000 of chargeable income is exempt from tax
• 50% of the next SGD 190,000 of chargeable income is also exempt

That's a maximum of SGD 102,500 of chargeable income exempted each year, which at 17% works out to a maximum tax saving of SGD 17,425 compared to having no exemption at all.

How Rebates and Exemptions Affect Your Tax Bill

Here's a worked example showing how the exemption and the rebate combine in practice.

Assume your company has SGD 200,000 of chargeable income for YA 2026, qualifies for SUTE, is eligible for the enhanced CIT Rebate, and also meets the condition for the SGD 2,000 CIT Rebate Cash Grant.

So instead of paying SGD 34,000 (17% of the full SGD 200,000), this company pays SGD 8,375 once the SUTE exemption and the YA 2026 rebate are both applied, a combined saving of SGD 25,625, or about 75% off the headline tax bill.

A 17% corporate tax rate sounds like a lot when you're running the numbers for a new business in Singapore. In practice, between the Start-Up Tax Exemption, the Partial Tax Exemption, and this year's enhanced corporate income tax rebate, most companies pay a fraction of that on their actual tax bill. None of it requires a separate application: it's built into how you file.
