The Enterprise Innovation Scheme: 400% deductions, explained

Until YA 2028, qualifying R&D, training and IP spending earns a 400% tax deduction — or a cash payout for loss-making startups. What qualifies and what it's worth.

How does Singapore's Enterprise Innovation Scheme work and what is it worth?

From YA 2024 to YA 2028, the EIS grants 400% tax deductions across five activities — R&D in Singapore, IP registration, IP acquisition or licensing, employee training, and innovation projects with institutions — generally capped at S$400,000 of spend per activity each year. Businesses meeting strict conditions, notably CPF contributions for at least three full-time local employees, can instead convert up to S$100,000 into a 20% cash payout worth up to S$20,000, applied for separately after filing.

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 five qualifying activities

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

ActivityEnhanced deductionCap on qualifying spend
R&D conducted in Singapore400%S$400,000
IP registration (patents, trade marks, designs)400%S$400,000
IP acquisition and licensing400%S$400,000
Employee training (SkillsFuture-eligible courses)400%S$400,000
Innovation projects with polytechnics, ITE and partner institutions400%S$50,000

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.
