Singapore corporate tax in 2025: 17% headline, but most companies pay less
Singapore's headline corporate income tax rate is a flat 17%, applied to a company's chargeable income for each Year of Assessment (YA). On paper that's already low by global standards. In practice, the effective rate is materially lower because of the Partial Tax Exemption (PTE), the Start-Up Tax Exemption (SUTE), a one-off 50% corporate income tax rebate for YA 2025, and indefinite carry-forward of unutilised losses. The calculator above applies the schemes in the order IRAS uses; this page explains what the numbers actually mean and which exemptions you qualify for.
Note the year terminology: Year of Assessment (YA) is the year you file; it taxes the financial year that ended in the preceding calendar year. So YA 2025 covers a financial year ending in 2024.
The two exemption schemes that drag the effective rate down
Partial Tax Exemption (PTE) — applies to almost every active company
Every company resident in Singapore (other than those eligible for SUTE) gets PTE on the first SGD 200,000 of normal chargeable income each YA:
- 75% exemption on the first SGD 10,000 → SGD 7,500 exempted
- 50% exemption on the next SGD 190,000 → SGD 95,000 exempted
- Maximum partial exemption per YA: SGD 102,500
Effective tax on the first SGD 200,000 of chargeable income works out to roughly 8.36%, not 17%. Above SGD 200,000, the full 17% rate applies on the excess.
Start-Up Tax Exemption (SUTE) — first three YAs only
SUTE replaces PTE for newly incorporated companies in their first three Years of Assessment, provided they meet the qualifying conditions:
- Incorporated in Singapore
- Tax resident in Singapore for that YA
- No more than 20 shareholders for the entire basis period
- At least one individual shareholder holds ≥10% of ordinary shares (or all 20 shareholders are individuals)
- Not a property/investment holding company (those are excluded since YA 2013)
When you qualify, exemptions are:
- 75% exemption on the first SGD 100,000 → SGD 75,000 exempted
- 50% exemption on the next SGD 100,000 → SGD 50,000 exempted
- Maximum SUTE per YA: SGD 125,000
A start-up using SUTE for three years and then transitioning to PTE will see its effective tax rate jump in YA 4 — that's the cliff most founders forget to budget for.
YA 2025 corporate income tax rebate and SkillsFuture top-ups
Budget 2024 introduced a 50% corporate income tax rebate for Year of Assessment 2025, capped at SGD 40,000 per company. The rebate is computed after PTE/SUTE and tax set-offs, and applied to the resulting payable tax. Companies that hired at least one local employee in calendar year 2024 also get a minimum cash grant of SGD 2,000 (the “CIT Rebate Cash Grant”), so even loss-making employers receive that floor.
The rebate is one-off: it does not apply to YA 2024 or YA 2026 unless explicitly extended in a future Budget. If you're modelling multi-year cash flow, only apply this in the YA 2025 row.
Worked example: a profitable Singapore Pte Ltd at SGD 500,000 chargeable income
Take a private limited company in YA 2025, not a start-up (so PTE applies, not SUTE), with SGD 500,000 of chargeable income after deducting allowable expenses, capital allowances and donations.
| Step | Amount (SGD) |
|---|---|
| Chargeable income before exemption | 500,000 |
| Less: PTE on first SGD 10,000 (75%) | (7,500) |
| Less: PTE on next SGD 190,000 (50%) | (95,000) |
| Net chargeable income after PTE | 397,500 |
| Tax at 17% | 67,575 |
| Less: 50% CIT rebate (capped at SGD 40,000) | (33,787.50) |
| Net corporate tax payable for YA 2025 | 33,787.50 |
| Effective tax rate on SGD 500k chargeable income | ≈ 6.76% |
The 50% CIT rebate stays well below the SGD 40,000 cap here. At higher chargeable income (around SGD 690,000+), the rebate hits its cap and the effective rate climbs back toward 17% on the marginal income above SGD 200,000.
Singapore-specific things that catch foreign founders out
- Tax residency is set by management and control, not incorporation. A Singapore Pte Ltd whose board meetings are held in another country can fail the residency test and lose both PTE rates and treaty benefits. Hold board meetings in Singapore (or document a clear management nexus there).
- One-tier dividend system: dividends are tax-free in shareholder hands.Corporate tax paid is final. Singapore does not levy further tax on dividends paid to either resident or non-resident shareholders, so there's no withholding on outbound dividends.
- Foreign-sourced income exemption (Section 13(8)) is not automatic.Foreign dividends, branch profits and service income can qualify for exemption, but only if the income was subject to tax in the source country at headline ≥15%, and the income is received in Singapore (constructive receipt rules apply). Read IRAS' e-Tax Guide before assuming exemption.
- GST registration kicks in at SGD 1 million in taxable supplies. The corporate-tax calculator does not include GST. Singapore GST is currently 9%; see the related Singapore GST calculator for that side of compliance.
- Capital allowances replace book depreciation. For tax purposes, claim initial allowance and annual allowance under Sections 19/19A of the Income Tax Act, not your accounting depreciation. Plant and machinery is typically written down over 3 years (or via the 1-year accelerated allowance for assets up to SGD 5,000).
- Loss carry-forward is indefinite, but subject to the substantial shareholder test.Unutilised tax losses, donations and capital allowances carry forward without time limit, but are forfeited if there's a substantial change (> 50%) in ultimate shareholders during the relevant comparison dates.
- Pillar Two / GloBE applies from FY 2025 for in-scope MNEs. Multinational groups with global revenue ≥ EUR 750 million face a 15% effective top-up tax under the Domestic Top-up Tax (DTT) and Income Inclusion Rule (IIR). For most SMEs this is irrelevant; for in-scope groups it overrides the calculator's effective rate at the group level.
Frequently asked questions
Is the 17% rate the actual rate I'll pay?
Almost never on the first SGD 200,000. PTE brings the effective rate down to about 8.4% on that first slice, and YA 2025 has an additional 50% rebate (capped at SGD 40,000). On chargeable income materially above SGD 200,000 the marginal rate is 17%, but the blended effective rate stays below the headline.
When does my company stop being eligible for SUTE?
SUTE is available only for YA 1, YA 2 and YA 3 — measured from the YA in which the company was incorporated. From YA 4 onwards you fall into the Partial Tax Exemption regime. Pre-empt the cliff: model both regimes for the transition year before locking in dividend or hiring decisions.
Are property/investment holding companies eligible for PTE?
Yes for PTE; no for SUTE. Property and investment holding companies were excluded from SUTE from YA 2013, but they remain eligible for the Partial Tax Exemption.
How are losses treated when there's a change in shareholders?
IRAS applies the substantial shareholder test: compare ultimate beneficial shareholders at the relevant dates. If more than 50% of the shareholding changes, unutilised losses, donations and capital allowances are forfeited unless the company applies for a waiver and the change is not for tax-avoidance purposes.
Does this calculator account for the YA 2025 50% CIT rebate?
Yes. The calculator applies PTE first, computes tax at 17%, then applies the 50% rebate capped at SGD 40,000 — matching IRAS' computation order. Toggle the YA selector if you need YA 2024 or YA 2026 figures (the rebate is YA 2025 only unless extended).
When are corporate tax filings due in Singapore?
Two filings: the Estimated Chargeable Income (ECI) is due within 3 months from financial-year end (with a waiver if revenue ≤ SGD 5 million and ECI is nil). The Form C-S/Form C-S (Lite)/Form C is due 30 November of the YA. Penalties for late filing start at SGD 200 and escalate.
