Corporate Tax Calculator Singapore

What Is a Corporate Tax Calculator Singapore?

A Corporate Tax Calculator Singapore estimates tax on a company’s normal chargeable income.

It applies the 17% corporate income tax rate, the selected exemption scheme and any tax set-offs entered. For YA 2026, it can also estimate the enhanced Corporate Income Tax rebate.

The result is an estimate. Actual tax may differ after tax adjustments, credits, incentives and the official assessment.

You can find more locally focused finance tools on the Calculator Singapores homepage.

What Does the Calculator Show?

The calculator estimates:

• Exempt income under PTE or SUTE
• Income remaining taxable at 17%
• Gross corporate tax
• Tax after entered set-offs
• YA 2026 CIT rebate
• Estimated net corporate tax
• Effective tax rate
• YA 2026 cash grant shown separately

It does not prepare an ECI filing, Form C-S, Form C-S Lite or Form C.

How to Use the Corporate Tax Calculator

1. Enter Normal Chargeable Income

Enter the company’s estimated normal chargeable income in Singapore dollars.

This is income remaining after applicable tax adjustments and tax-allowable deductions. Do not automatically enter accounting profit before tax.

For a broader view of different Singapore taxes, use the Singapore Tax Calculator.

2. Select the Exemption Scheme

Choose one option:

• Partial Tax Exemption
• Qualifying Start-up Tax Exemption
• No PTE or SUTE exemption

Select SUTE only when the company meets its qualifying conditions.

3. Select the Year of Assessment

Select YA 2026 to apply the enhanced YA 2026 CIT rebate.

Select Other YA only for YA 2020 onwards when you want a calculation without a CIT rebate. The calculator does not apply rebate rules from other years and should not be used for exemption rules before YA 2020.

4. Enter Tax Set-offs or Credits

Enter applicable tax set-offs or credits before the CIT rebate.

Leave this field at zero when no set-off applies. Do not enter a credit that has already been deducted from the chargeable income.

Tax and borrowing are separate calculations. The Bank Loan Calculator Singapore estimates loan repayments and does not calculate corporate tax.

5. Choose Cash Grant Eligibility

This field appears when YA 2026 is selected.

Choose Yes only if the company is active and meets the applicable local employee condition. Choose No/Not sure when eligibility has not been confirmed.

6. Calculate the Result

The result displays:

• Estimated Net Corporate Tax
• Tax Before YA 2026 Rebate
• Effective Tax Rate
• Calculation breakdown
• Cash grant shown separately, when selected

Select Reset to clear the information and restore the default options.

Singapore Corporate Income Tax Rate

Singapore’s standard corporate income tax rate is 17% of chargeable income.

The rate applies to local and foreign companies. However, the effective rate may be lower after PTE, SUTE or an applicable rebate.

The calculator applies 17% only to normal chargeable income. It does not calculate income taxed at concessionary rates or under special incentives.

Partial Tax Exemption

For YA 2020 onwards, PTE provides:

• 75% exemption on the first S$10,000 of normal chargeable income
• 50% exemption on the next S$190,000

The maximum exempt amount is S$102,500 on the first S$200,000.

Normal chargeable income left after this exemption is taxed at 17%.

Start-up Tax Exemption

SUTE applies only to qualifying companies during their first three consecutive Years of Assessment.

For YA 2020 onwards, it provides:

• 75% exemption on the first S$100,000
• 50% exemption on the next S$100,000

The maximum exempt amount is S$125,000 on the first S$200,000.

A new company does not qualify automatically. Its incorporation, tax residence, shareholders and main business activity must meet the applicable conditions.

Investment holding companies and companies undertaking property development for sale, investment or both do not qualify for SUTE. They may still qualify for PTE.

Corporate Tax Formula

The calculator first finds the exempt amount under the selected scheme.

Income taxed at 17% = Normal chargeable income − Exempt amount

It then calculates gross tax:

Gross corporate tax = Income taxed at 17% × 17%

Entered set-offs are deducted next:

Tax before CIT rebate = Gross corporate tax − Tax set-offs

For YA 2026:

Estimated net tax = Tax before rebate − Applicable CIT rebate

The effective rate is:

Effective tax rate = Estimated net tax ÷ Normal chargeable income × 100

The cash grant is displayed separately. It is not directly deducted from the Estimated Net Corporate Tax figure.

Corporate Tax Calculation Example

Assume the company enters:

• Normal chargeable income: S$100,000
• Exemption scheme: PTE
• Year: YA 2026
• Tax set-offs: S$0
• Cash grant: No/Not sure

PTE exemption

75% of the first S$10,000:

S$10,000 × 75% = S$7,500

50% of the next S$90,000:

S$90,000 × 50% = S$45,000

Total exempt amount:

S$7,500 + S$45,000 = S$52,500

Income taxed at 17%

S$100,000 − S$52,500 = S$47,500

Gross tax

S$47,500 × 17% = S$8,075

YA 2026 rebate

With no set-offs, tax before rebate is S$8,075.

S$8,075 × 50% = S$4,037.50

Estimated net tax

S$8,075 − S$4,037.50 = S$4,037.50

The estimated effective tax rate is approximately 4.04%.

YA 2026 CIT Rebate and Cash Grant

The enhanced YA 2026 CIT rebate is 50% of corporate tax payable.

The rebate is calculated after applicable tax set-offs. The combined maximum benefit from the rebate and cash grant is S$40,000.

The enhanced cash grant is S$2,000 for an eligible active company that meets the local employee condition. Generally, the company must have made CPF contributions for at least one Singapore citizen or permanent resident employee in 2025. A shareholder who is also a company director does not count for this condition.

If the company qualifies for the S$2,000 cash grant, the maximum separate CIT rebate is S$38,000 so that the combined benefit does not exceed S$40,000. If the calculated rebate is S$2,000 or less, no separate CIT rebate is given because the company receives the S$2,000 cash grant instead. The calculator shows this amount separately and adjusts the rebate calculation when eligibility is selected.

Current corporate tax rates, exemptions and YA 2026 conditions are published by IRAS.

Selecting Yes does not confirm cash-grant eligibility. The official decision is made during assessment.

Corporate Tax and Other Business Calculations

Corporate income tax is based on chargeable income. GST and service charge relate to customer transactions and bills.

The Singapore Service Charge And GST Calculator estimates service charge and GST on a bill. Its result is not the same as a company’s chargeable income.

Business financing must also be calculated separately. The Singapore Corporate Business Loan Calculator estimates loan payments, while this page estimates corporate tax.

Loan proceeds are not normal chargeable income merely because the company receives cash. Financing expenses may also require tax adjustments before they are deductible.

An asset’s value is different from taxable income. The Gold Price Calculator Singapore estimates gold value but cannot decide whether a gain, loss or expense is taxable.

The Faraid Calculator Singapore estimates the estate remaining after the entered expenses, debts and religious obligations. It does not calculate corporate tax or determine beneficiaries’ inheritance shares.

What the Calculator Cannot Determine

The calculator cannot determine:

• Actual chargeable income
• Whether every expense is deductible
• SUTE or cash-grant eligibility
• Tax residency
• Capital allowance claims
• Carried-forward losses
• Group relief
• Foreign tax credits
• Concessionary rates
• Special incentives
• Filing obligations
• Final tax assessed

It also does not calculate GST, withholding tax or personal income tax.

Common Mistakes

Entering Accounting Profit

Accounting profit and normal chargeable income are not always the same. Enter the figure after relevant tax adjustments and allowable deductions.

Selecting SUTE Without Qualifying

SUTE is limited to qualifying companies during their first three consecutive YAs. Select PTE or No Exemption when SUTE does not apply.

Using YA 2026 for Another Year

Select Other YA when the enhanced YA 2026 rebate does not apply.

Counting a Set-off Twice

Do not enter a set-off that has already reduced the chargeable income or tax figure.

Treating the Cash Grant as Confirmed

Selecting Yes only changes the estimate. It does not confirm eligibility or payment.
