Singapore's 400% AI tax deduction, in cash terms

The short version: you already deduct business expenses at 100%. The scheme lets qualifying AI spend be deducted at 400% — an extra 300% on top of the normal deduction — capped at S$50,000 of spend per Year of Assessment, for YA2027 and YA2028. At Singapore's 17% headline corporate tax rate, a profitable company spending the full S$50,000 gets roughly S$25,500 of extra tax relief it would not otherwise have had. It is a reduction in tax payable, not a cash grant, and it is only worth something if you are paying tax.

Policy details on this page were checked on 26 September 2026 against the announcing agency's own materials. Schemes, caps and dates change — confirm the current position with the administering agency, and with your own tax or grant adviser, before relying on anything here.

The arithmetic, worked through

Take a profitable company spending S$50,000 on qualifying AI in a Year of Assessment.

• Without the scheme: deduct S$50,000. Tax saved at 17% = S$8,500.
• With the scheme: deduct S$200,000 (400%). Tax saved at 17% = S$34,000.
• The difference — the actual benefit: S$25,500.

So the scheme covers a little over half the spend, in the form of tax you do not pay. That is a genuinely strong incentive, and it is not 400% of anything you get back. The 400% figure describes the deduction, which is why the headline reads better than the cheque.

Two conditions matter more than the percentage. You have to be profitable — a deduction reduces taxable income, so a company with no taxable income gets nothing from it this year. And the cap is on spend, not on relief: S$50,000 of qualifying spend per Year of Assessment is the ceiling, so a S$200,000 project does not scale the benefit.

Deduction or grant — they are different instruments

The EDGE Grant is the route for a project delivered with a vendor or consultant, and it replaced PSG, EDG and MRA for new applications from 30 September 2026 — see what replaced PSG, EDG and MRA.

The question to ask before assuming you get both

Grant-funded expenditure and tax deductions interact, and the general principle across Singapore's schemes is that you do not get tax relief on money someone else paid. If part of a project is reimbursed by a grant, the deductible amount is normally the part you actually bore.

We are not your tax adviser and this is the point to involve one. The specific question worth asking is: "For this project, which costs are grant-supported, which are not, and what is the qualifying base for the EIS AI deduction after the grant?" Ask it before the project, because the answer sometimes changes how you would structure it — for instance, whether a piece of work is scoped inside the grant application or outside it.

What is likely to qualify, and what to document

The scheme sits inside the Enterprise Innovation Scheme, which has always leaned toward innovation activity rather than routine operating costs. Without pre-judging IRAS's treatment of your specific spend, the distinction that tends to matter is between building or adopting a capability and running the business as before with a subscription attached.

What to keep regardless:

• An invoice trail that names the AI work specifically rather than burying it in a general IT line.
• A short written description of what was built or adopted and what changed as a result.
• The grant position on the same costs, if any.
• Dates, because the AI category applies to YA2027 and YA2028 and the boundary matters.

That documentation is also, not coincidentally, what a grant claim wants. Doing it once serves both.

The rest of the Budget 2026 AI package

• S$150 million for the Enterprise Compute Initiative, pairing companies with cloud and AI providers — aimed at the cost and access barrier rather than the project itself.
• S$37 billion under RIE2030, the national research and innovation envelope. Not an SME instrument, but it is where the capability being commercialised around you comes from.
• Over 70 AI Centres of Excellence established in Singapore by technology and industrial companies.

The strategic context for all of it is in the National AI Strategy update.

A sensible sequence

1. Decide the project — one process, ninety days, a measurable change. Not "adopt AI".
2. Check EDGE eligibility and apply before you start. Grants are not retrospective.
3. Ask your tax adviser the qualifying-base question above, with the grant position in hand.
4. Keep the paperwork as you go. Reconstructing it at year end is where the benefit quietly gets lost.

This is general information, not tax advice. Scheme parameters, qualifying conditions and Years of Assessment change; confirm the current position with IRAS and a qualified tax adviser before relying on it.
