Singapore Corporate Tax Exemptions for Startups (Updated 2026)

Could a newly launched local venture really owe just 6.4% in tax? Clear the qualifying hurdles and the answer is yes — that is roughly the rate once taxable earnings hit S$200,000, before the 50% CIT Rebate for YA 2026 is even factored in.

In this article, we explain how the Singapore startup tax exemption works in 2026 and which companies qualify. We also cover how much tax a new company saves and the exact steps to claim it correctly with IRAS.

What Is the Tax Exemption Scheme for New Singapore Start-Ups?

Set out in the Income Tax Act 1947, the scheme exempts 75% of a fledgling company's opening S$100,000 of taxable profit, plus half of the S$100,000 after that, for the company's first three YAs.

Launched in YA 2005 to nurture budding local enterprises and new venture creation, the scheme is administered by IRAS. The headline tax stays flat at 17% in YA 2026; the relief works by trimming the portion of earnings on which that 17% is actually charged.

No election or opt-in is needed. Where the eligibility tests are satisfied, IRAS grants the relief without any separate form or application; the only task left is completing the relevant sections of the yearly return. In practice, we help newly incorporated clients map out their opening three YAs in advance, so the relief is not wasted on low-earning or loss-making periods.

For these purposes, only ordinary taxable earnings count: the figure left after allowable deductions but before the tax-free slice is stripped out. A company that ends the period in the red gets no benefit for that YA, yet that YA still uses up part of the qualifying window.

Which Companies Qualify for the Start-Up Tax Exemption?

A company passes all three of IRAS's cumulative tests only if it:

• is formed in Singapore and is a Singapore tax resident for that YA;
• keeps its shareholder count at 20 or fewer for the entire basis period;
• is owned wholly by individuals, or counts at least one individual who beneficially owns 10% or more of the issued ordinary shares.

IRAS applies three cumulative tests, and a company must satisfy every one of them for the particular YA. The tests cover where the company is formed, who owns it, and when it claims. This is why company incorporation in Singapore matters from the start.

1. Incorporation and Tax Residency

The company must be incorporated in Singapore. This is why the exemption matters when planning company incorporation in Singapore. It must also be a Singapore tax resident for that YA. That means its business control and management are exercised in Singapore. A Singapore branch of a foreign company does not qualify. It is simply taxed at 17% on its Singapore-sourced income.

2. Shareholding Conditions

Throughout the basis period for the YA, the company must have no more than 20 shareholders. All shareholders must be individuals, or one individual shareholder must hold at least 10% of the issued ordinary shares. That individual must hold the shares beneficially and directly. A company whose principal activity is investment holding or property development is expressly excluded under the scheme's qualifying conditions; the relief is reserved for active trading businesses.

3. Timing: The First Three Consecutive YAs

The exemption is available only for a company's first three consecutive YAs. From the fourth YA onwards, the company falls back on the partial tax exemption available to all companies. Because the window is fixed, start-ups expecting losses in early years should consider deferring the first YA. For example, they can choose a financial year end that delays the first profitable basis period.

How Much Tax Does a New Start-Up Actually Save?

A qualifying company pays an effective rate of about 6.4% on its first S$200,000 of chargeable income. That saves up to S$21,250 in tax per YA.

The exemption bands have applied from YA 2020 onwards and remain unchanged for YA 2026. The maximum exempt income is S$125,000 per YA, worth S$21,250 of tax saved at the 17% rate. Worked example one: on S$100,000 of chargeable income, S$75,000 is exempt, leaving S$25,000 taxable and tax of S$4,250, an effective rate of 4.25%. Worked example two: on S$200,000 of chargeable income, the exempt amount reaches the full S$125,000, leaving S$75,000 taxable and tax of S$12,750, an effective rate of exactly 6.375% (usually quoted as 6.4%). The 6.4% figure applies only at the S$200,000 level; below that threshold, the effective rate is lower — 4.25% at S$100,000, for instance.

What Budget 2026 Changes Should Start-Ups Know About?

For YA 2026, every taxpaying company receives a 50% CIT Rebate on its tax payable. Active companies that made CPF contributions to at least one local employee, excluding shareholder-directors, in 2025 receive a S$2,000 CIT Rebate Cash Grant.

The 50% CIT Rebate was unveiled in Budget 2026 and extends to every company with tax to pay, regardless of its tax residence. The rebate is measured against the bill left once the start-up or partial exemption has been deducted, so the more relief a company already enjoys, the smaller its rebate will be. The S$2,000 CIT Rebate Cash Grant sits alongside it and works on a separate basis. What matters for the grant is the local-employment condition, not the size of the tax bill, so an eligible firm receives the full S$2,000 even where its rebate is modest.

The combined value of the rebate and the grant is capped at S$40,000 per company. For many start-ups, the S$2,000 floor is the more valuable half of the package, because the exemption may already have cut the tax payable to a small figure. According to IRAS, the rebate is computed automatically, so nothing further is needed from the company.

What Happens Once the Start-Up Exemption Ends?

From the fourth YA onwards, a company claims the partial tax exemption. It gets 75% exemption on the first S$10,000 of chargeable income and 50% on the next S$190,000.

The partial tax exemption is available to all companies. It includes Singapore branches of foreign companies. It continues every year without a qualifying window. The maximum exempt income under this scheme is S$102,500 per YA. This is worth S$17,425 of tax saved.

Businesses scaling beyond the start-up phase should model this step-down early. The effective rate on S$200,000 of chargeable income rises under the partial exemption. Before the YA 2026 CIT Rebate, the effective rate rises from roughly 6.4% under the start-up scheme to about 8.3% under the partial exemption. This difference affects cash flow planning and the year-end tax provision.

How Should a Start-Up Claim the Exemption in YA 2026?

No claim form is needed: the exemption applies automatically once a company qualifies. The essential filing is the annual tax return, so e-file Form C-S, Form C-S (Lite) or Form C by 30 November 2026 with the exemption sections completed. ECI reporting within three months of the financial year end may be waived for small companies.

Directors remain responsible for timely and accurate filing. This applies even when a Corporate Services Provider or tax agent has been engaged. Late filing or non-filing may attract penalties of up to S$5,000. Key deadlines, such as the 30 November 2026 return filing date, should be diarised well in advance. Reliable corporate secretarial services for startups help keep these deadlines visible to the board. Contact our team to set up a filing calendar.

1. File Estimated Chargeable Income Within Three Months

ECI must be filed within three months of the financial year end. This is unless the company qualifies for the administrative waiver. The waiver applies where annual revenue is S$5 million or below and ECI is nil. ECI is measured before deducting any exempt amount. For a 31 December 2025 financial year end, the ECI deadline was 31 March 2026.

2. E-File the Correct Form by 30 November 2026

Form C-S is the option most new businesses use. Locally incorporated entities may choose it provided that:

• turnover for the year does not exceed S$5 million,
• all income is taxed at the prevailing 17% rate,
• there is no carry-back claim for capital allowances or losses,
• there is no claim for group relief, investment allowance, foreign tax credits, or tax deducted at source.

Where turnover is S$200,000 or below, a Form C-S (Lite) option opens up that needs just six key entries.

3. Complete the Exemption Sections Accurately

The start-up or partial exemption is claimed by completing the relevant sections of the ECI and the annual return. The claim must reconcile with the tax computation. Supporting schedules should be retained. We help clients prepare the full corporate income tax filing package. This includes the tax computation and submission. The exemption claim should withstand IRAS review.

Conclusion

Few jurisdictions hand an early-stage venture a tax deal this good. An eligible young business keeps three quarters of its opening S$100,000 of taxable profit outside the tax net, plus half of the next S$100,000, and this treatment runs for three back-to-back YAs. YA 2026 then stacks a 50% CIT Rebate on top, along with a minimum payout of S$2,000 by way of a grant for firms that satisfy the local-employment test.

Whether a business can enjoy these reliefs turns on structural decisions made at formation: the make-up of the share register, where control and management actually sit, and the timing of the opening YA. Getting these calls right from day one safeguards a saving worth up to S$21,250 a year. Getting them wrong forfeits the relief for good.
