Summary:

Singapore’s 17% corporate tax rate isn’t what most businesses pay. Exemptions, enhanced deductions, capital allowances and the YA 2026 rebate (50% of tax payable, capped at S$40,000 with the cash grant) can all lower the final bill, but only if you plan and claim them. Schemes like the Enterprise Innovation Scheme offer up to a 400% deduction on eligible spending, while individuals can reduce personal tax through SRS and CPF top-ups before 31 December 2026. With the corporate filing deadline on 30 November, now is the time to review your claims, records and eligibility. Speak to IMC for a tax-planning review before the year closes.

Companies in Singapore pay a corporate tax rate of 17%, but that does not always reflect the amount they eventually owe. The final bill may be lower after factoring in tax exemptions, deductions, and rebates. However, the business needs to plan ahead and claim the eligible deductions. Currently, two dates are close. These are 30th November for corporate filing and 31st December for personal top-ups. A well-planned approach to reduce taxable income Singapore businesses report can make a significant difference to their tax position.

How chargeable income works

Tax is levied on chargeable income, which differs from the profit in the accounts. A company starts with revenue and deducts the expenses it incurred wholly and exclusively to earn it. Capital allowances and unused losses come off next, and the remaining amount is taxed. Each step in that chain is a point where Singapore tax reliefs and deductions can lower the bill. Every one of them is legitimate planning under the rules.

Corporate exemptions and rebates

The first slice of income is shaped by two schemes. In the first three years of assessment, a new company enjoys the Start-Up Tax Exemption. This helps it get 75% of the first S$100,000 and 50% of the next S$100,000 excepted. Partial exemption applies to other companies, which exempts 75% of the first S$10,000 and 50% of the next S$190,000.

For YA 2026, the scenario improved in April. The Singapore corporate tax rebate YA 2026 now stands at 50% of tax payable. The cap is S$40,000, including the cash grant. Active companies that paid CPF for a local employee in 2025 receive a grant of at least S$2,000. IRAS applies both to the filed return, and a clean filing is all that is needed.

Enhanced deductions

Businesses can claim higher tax deductions on certain expenses. The Enterprise Innovation Scheme Singapore is available from YA 2024 to YA 2028. It offers a 400% tax deduction on the first S$400,000 spent each year on eligible activities. These include research and development (R&D), IP registration, IP licensing and acquisition, and approved training. Businesses can also choose to receive a 20% cash payout on up to S$100,000 of eligible spending, capped at S$20,000.

Businesses can also consider:

International expansion: 200% deduction on eligible internationalisation expenses under the Double Tax Deduction for Internationalisation scheme.
AI adoption: Qualifying AI adoption expenditure will receive a 400% deduction on the first S$50,000 for YA 2027 and YA 2028.
Donations: 250% tax deduction for qualifying donations to approved IPCs and the Singapore Government, subject to applicable conditions.

Companies planning to expand overseas can also claim tax benefits. The double tax deduction for internationalisation allows a 200% deduction on eligible expenses. Its automatic claim limit will increase from S$150,000 to S$400,000 in YA 2027. Donations to approved charities qualify for a 250% tax deduction.

Capital allowances, losses and credits

In the tax computation, capital allowances replace accounting depreciation. Most plant and machinery are written off over its working life, or over three years by election.

Companies can carry forward their unused losses to future years if they meet the shareholding test. They can also carry back up to S$100,000 in losses to the previous year. Under group relief, related companies can share losses if they have the same financial year-end and meet the 75% shareholding requirement.

Companies earning income overseas may also qualify for tax relief under a tax treaty, foreign tax credit or Section 13(8) exemption. IMC can review the accounts of a company and help in identifying the tax benefits out of these that it can claim. The professionals offer valuable Tax advisory services in Singapore to help businesses make the most of tax benefits.

Personal tax reliefs for individuals and year-end contributions

Residents in Singapore pay progressive rates ranging from 0% to 24%. Tax reliefs can help lower the amount they owe, particularly for those in the higher tax brackets. Before the year ends, two options are worth considering.

Contribution	Annual limit
SRS – Singapore citizens and PRs	S$15,300
SRS – Foreigners	S$35,700
Eligible CPF cash top-ups – Self	S$8,000
Eligible CPF cash top-ups – Family members	Additional S$8,000

The first is contributing to the Singapore SRS CPF tax relief scheme. The cap is S$15,300 for citizens and permanent residents, and S$35,700 for foreigners. Individuals can also claim tax relief on cash top-ups to their own CPF accounts and those of family members, up to S$8,000 for each. However, the total personal tax relief is capped at S$80,000 a year. To qualify for YA 2027, the contributions must be made by 31st December 2026.

Mistakes to avoid as you reduce taxable income Singapore

December is the most common trap. A top-up, a hire, or an equipment purchase requires lead time. A decision made in the last week is often rushed, and at times, businesses miss out on the schemes. The Enterprise Innovation Scheme and its cash payout reward companies that check eligibility early.

Keeping proper records is just as important. Receipts, contracts and payroll documents help in strengthening your tax claims. With the YA 2026 filing deadline on November 30th, November is a good time to review all your claims. Regular taxation services in Singapore can also help businesses manage their tax work throughout the year instead of leaving the priorities until the deadline.

Prepare Before the Filing Deadline

A year-end tax review should cover:

Allowable business expenses and non-deductible items.
Capital expenditure and capital allowance claims.
Eligibility for enhanced deductions and tax exemptions.
Supporting invoices, contracts and payroll records.
Unutilised losses and group relief opportunities.
Corporate tax filing requirements.

Important deadlines

Date	Requirement
30 November 2026	YA 2026 corporate income tax filing
31 December 2026	Eligible SRS contributions and CPF cash top-ups for YA 2027 personal tax relief
