The Enterprise Innovation Scheme: 400% deductions, explained

Most owners know the ordinary rule: a business expense is deductible once. The Enterprise Innovation Scheme breaks that rule deliberately: for YA 2024 through YA 2028, qualifying innovation spending is deducted four times over — and loss-making companies can take cash instead.

The six qualifying activities

Each activity carries its own annual expenditure cap, per YA:

The AI activity is the newest and the most conditional: announced at Budget 2026, it applies only to YA 2027 and YA 2028, excludes hardware, and is the one activity the cash payout cannot be used for (IRAS). It also sits in its own draft provision rather than inside the sections behind the other five, so the same invoice cannot be claimed under both. The AI expenditure deduction guide covers what qualifies, the bundled-invoice apportionment rule, and its status as proposed law.

Spending above a cap still earns the normal 100% deduction. The caps reset each YA and cannot be pooled across years — timing large projects across two YAs can double the enhanced benefit.

What it is worth

The arithmetic: S$100,000 of qualifying R&D removes S$400,000 from chargeable income — up to S$68,000 of tax saved at the 17% rate. Two practical qualifications:

• If the start-up or partial exemption already shelters most of your profit, the marginal value of extra deductions falls — a genuinely common situation for young companies, and worth modelling before spending "for the deduction";
• Enhanced deductions that create or deepen a loss join your carry-forward balances, with the conditions that entails.

The cash payout — designed for startups

A business can elect to convert up to S$100,000 of qualifying expenditure per YA into a non-taxable cash payout at 20% — up to S$20,000 cash. Useful for a pre-profit startup, but the eligibility conditions are strict and are where expectations go wrong. Per IRAS, the business must:

• be carrying on active trade or business operations in Singapore when the payout is disbursed;
• have made CPF contributions for at least three full-time local employees — Singapore citizens or PRs earning at least S$1,400 a month — for at least six months of the basis period;
• have incurred at least S$400 of qualifying expenditure in the basis period.

That three-employee condition rules out a large share of very early startups — the exact companies most attracted by the cash. Check it before budgeting for the money.

Note also that the payout is not automatic with the return: only one application per YA is allowed, made separately after filing, so all converted expenditure must go in a single submission. Where IP registration costs are converted, the related rights must generally be held for at least a year. The election is irrevocable for the converted spend and trades a potentially larger future deduction for certain cash now — a genuine decision, best taken with your tax adviser each year.

Claiming without drama

The enhanced deductions are claimed in the corporate tax return with no separate approval; the cash payout requires its own application after filing. Either way the discipline is documentary:

1. Tag qualifying spend as it happens — project records for R&D (what was novel, what was resolved), registration documents for IP, course and funding eligibility for training;
2. Keep the records — enhanced claims attract review precisely because they are lucrative, and an unsupported claim is disallowed with interest on the shortfall;
3. Decide deduction vs payout before filing, not after.

R&D is where definitions bite hardest: routine development, cosmetic changes and market research do not qualify; work resolving scientific or technological uncertainty does. When in doubt, the claim is worth a professional's hour before it is worth four times the deduction.

The EIS expires after YA 2028 unless extended. If innovation spending is on your roadmap anyway, the scheme is a standing argument for doing it inside the window — the same spending two years late may be worth a quarter as much.
