The one-paragraph answer
Under Singapore's Enterprise Innovation Scheme (EIS), Singapore companies can claim a 400% tax deduction on qualifying AI expenditure, capped at SGD 50,000 per year of assessment across YA2027 and YA2028. That translates to a maximum tax saving of SGD 34,000 on SGD 50,000 of AI spend at Singapore's 17% corporate income tax rate. The full IRAS qualifying expenditure list for AI is still pending, expected mid to late 2026, so CFOs modelling now must work from the published Income Tax Act amendments and preliminary IRAS communications.
What is Singapore's 400% AI tax deduction?
The 400% AI tax deduction is a new qualifying activity added to Singapore's Enterprise Innovation Scheme (EIS) under Budget 2026. AI expenditure joins the existing EIS categories of R&D, IP registration, IP acquisition, training, and innovation projects with qualified partners.
Under the EIS, qualifying companies can deduct 400% of their qualifying AI expenditure from taxable income, up to SGD 50,000 per year of assessment. The AI category applies to two years of assessment only, YA2027 and YA2028, covering financial years FY2026 and FY2027.
The mechanics work as follows. For every SGD 100 spent on qualifying AI, a company can deduct SGD 400 from taxable income. At Singapore's 17% corporate income tax rate, that produces SGD 68 in tax savings on SGD 100 of spend. Net cost is SGD 32 for every SGD 100 spent, provided the company has sufficient taxable income to absorb the deduction.
How much can Singapore companies actually save?
The numbers work out to significant savings for companies willing to time their AI spend correctly.
| Scenario | AI spend per year | 400% deduction | Tax saving at 17% CIT | Net cost |
|---|---|---|---|---|
| Small deployment | SGD 10,000 | SGD 40,000 | SGD 6,800 | SGD 3,200 |
| Cap-hitting deployment | SGD 50,000 | SGD 200,000 | SGD 34,000 | SGD 16,000 |
| Two years cap-hitting | SGD 100,000 across YA2027 and YA2028 | SGD 400,000 | SGD 68,000 | SGD 32,000 |
The SGD 50,000 annual cap is per year of assessment, not per project. A company that spends SGD 60,000 in YA2027 does not roll the excess into YA2028. The extra SGD 10,000 receives no enhanced deduction. Timing matters.
Who qualifies for the deduction?
The EIS applies to Singapore-incorporated companies that are tax residents of Singapore. Small and medium enterprises, startups, and larger corporates all qualify, provided they have taxable income to offset.
The scheme is not automatic. Companies must claim the deduction in their tax return for YA2027 or YA2028. The AI expenditure must be documented, and IRAS reserves the right to review claims for eligibility.
Companies with no taxable income in YA2027 or YA2028 cannot benefit from the deduction. The EIS does not provide a cash payout option for AI expenditure. This is different from some other EIS categories that do allow cash conversion.
When does the deduction apply?
The deduction applies to two years of assessment only.
| Year of assessment | Financial year covered | Claim window |
|---|---|---|
| YA2027 | FY2026 (Jan 1 to Dec 31, 2026) | Tax filing in 2027 |
| YA2028 | FY2027 (Jan 1 to Dec 31, 2027) | Tax filing in 2028 |
There is no carry-forward beyond YA2028. AI spend in FY2028 and beyond returns to standard corporate tax treatment. This creates a two-year planning window that closes on December 31, 2027.
What AI expenditure qualifies for the deduction?
This is the key open question. IRAS has published the enabling legislation but has not yet released the definitive qualifying expenditure list for AI. The full IRAS guidance is expected in mid to late 2026.
Based on the published Income Tax Act amendments and EnterpriseSG's public positioning, the following categories are almost certainly qualifying expenditure:
- Third-party AI software licensing (enterprise SaaS AI platforms)
- AI-specific cloud compute (GPU cloud, dedicated AI inference)
- AI model fine-tuning services from qualified providers
- Certified AI training and upskilling programmes for staff
Categories that may or may not qualify pending IRAS guidance:
- Internal AI development salaries (only qualifying portion)
- Data preparation and labelling services
- AI consulting from third parties (some services yes, some no)
- AI-adjacent infrastructure (for example, data platform overhauls)
Categories unlikely to qualify:
- General cloud infrastructure not specifically for AI
- Generic productivity software (Microsoft 365, Google Workspace)
- Non-AI professional services
- Hardware purchases (laptops, workstations)
Until IRAS publishes the definitive list, CFOs should document all AI-related expenditure with sufficient specificity that reclassification is possible either way.
Can Singapore companies stack EIS with PSG grants?
Yes, with restrictions. Companies can stack the Productivity Solutions Grant (PSG) with the EIS 400% deduction, but on different portions of the same project.
The Productivity Solutions Grant (PSG) provides up to 50% co-funding on approved digital solutions from EnterpriseSG's pre-approved vendor list, capped at SGD 30,000 per project. The EIS 400% deduction applies to qualifying AI expenditure that is not already subsidised by grants.
Practical stacking approach:
- Identify the total qualifying AI investment
- Apply PSG on the subsidisable portion (typically the software or licensing cost from a pre-approved vendor)
- Apply EIS 400% deduction on the remaining self-funded portion
- Document both claims separately for IRAS review
The stacking play is worth modelling on any AI investment above SGD 40,000. Below that threshold, PSG alone may be simpler and more valuable than EIS structuring.
What should Singapore CFOs do now, before IRAS publishes guidance?
Waiting for IRAS guidance is the expensive option. The planning window closes faster than most finance teams calendar it.
Three moves worth making this quarter:
Move 1. Build the AI expenditure inventory
Catalogue every AI-adjacent line item budgeted for FY2026 and FY2027. Include cloud, software, licensing, training, and third-party services. Tag each item with a qualifying-probability score (high, medium, low) based on the guidance above. Without the inventory, the deduction opportunity gets missed by default.
Move 2. Time the AI spend across YA2027 and YA2028
The SGD 50,000 cap is per year. Companies with SGD 80,000 of planned AI spend over 24 months should split it as evenly as possible across the two years of assessment. Companies with SGD 30,000 planned should consider accelerating additional spend into the cap year to maximise the deduction.
Move 3. Structure the PSG-EIS stack now
Do not wait for the AI project to be underway to consider grants. The PSG pre-approved vendor list is available now. Identify vendors whose solutions can absorb part of the AI investment, structure the grant application, then apply EIS on the remaining self-funded portion.
The one thing not to do is commit large AI expenditure in Q4 2026 without the guidance published. Wait for IRAS if the spend can be timed. Commit now only if the business need is unavoidable.
Frequently asked questions
Is the 400% AI tax deduction automatic?
No. Companies must claim the deduction in their annual tax return for YA2027 or YA2028. Supporting documentation must be maintained for IRAS review.
Can early-stage startups without profits benefit?
Not through the deduction mechanism, since it reduces taxable income. Startups without taxable income should focus on PSG and other grant schemes that provide direct funding.
Does the deduction apply to overseas AI vendors?
The AI expenditure must be for the Singapore company's operations. Payments to overseas vendors for services delivered in Singapore should qualify, provided the arm's-length pricing and substance requirements are met.
What happens if IRAS disqualifies a claim after filing?
IRAS may issue additional tax assessments if a claim is disallowed after review. Interest and potential penalties apply. Documentation is critical to defend the position.
Can the deduction be applied retroactively to FY2025 AI spend?
No. The scheme only applies to qualifying AI expenditure in FY2026 (YA2027) and FY2027 (YA2028).
Where can I read the full IRAS guidance?
The full qualifying expenditure list for AI under the EIS is expected in mid to late 2026 at iras.gov.sg. This page will be updated when the guidance is published.
Is there a limit on the type of company that can claim?
Singapore tax residents that are companies (Pte Ltd, Ltd, subsidiaries of foreign parents that are tax resident in Singapore) all qualify. Partnerships and sole proprietorships are subject to different rules under the Income Tax Act.
