Angel Investors Tax Deduction (AITD) Scheme: Why This Startup Tax Break Lapsed
The scheme once let approved angel investors deduct 50% of qualifying startup investments — here’s its current status.
The Angel Investors Tax Deduction (AITD) Scheme was a Singapore tax incentive that allowed individuals with approved angel investor status to claim a tax deduction of 50% of amounts invested in qualifying Singapore start-up companies. The scheme has lapsed, with no new approved-investor status or fresh qualifying investments accepted after 31 March 2020.

Key Takeaways
- The AITD Scheme was introduced in Budget 2010 and allowed a 50% tax deduction on qualifying investments made in approved Singapore start-ups.
- It applied only to investments made between 1 March 2010 and 31 March 2020, after which the scheme lapsed by design, without being renewed.
- Investors who held approved angel investor status and made qualifying investments before the cut-off date continue to enjoy the deduction for those specific investments, provided original conditions like the minimum holding period are still met.
- The scheme required prior IRAS approval of angel investor status, plus each investment had to be in a company meeting specific ‘qualifying start-up’ criteria at the time.
- Angel investors funding Singapore startups today do so without this specific tax deduction, though other avenues such as the Section 13O and 13U family office tax incentives serve different investor profiles.
What Was the AITD Scheme?
The Angel Investors Tax Deduction Scheme was designed to encourage high-net-worth individuals to invest directly in early-stage Singapore companies by offsetting some of the risk with a tax benefit. An approved angel investor who put capital into a qualifying start-up could deduct 50% of the investment amount against their taxable income, up to a cap, spread over a defined period, provided they held the investment for a minimum period (generally two years) and the underlying company continued to meet qualifying conditions.
Approval was not automatic. An individual first had to apply to be recognised as an approved angel investor, demonstrating relevant experience or track record, and each specific investment then had to be in a company meeting IRAS’s qualifying start-up definition, which typically covered early-stage, Singapore-incorporated companies below certain size and age thresholds.
Why the Scheme Was Allowed to Lapse
The AITD Scheme was structured from the outset with a built-in sunset: it was legislated to cover investments made only within a defined window, from 1 March 2010 to 31 March 2020. Budget 2020 confirmed the scheme would not be renewed or extended, meaning no new approved angel investor status has been granted, and no investments made after that cut-off date qualify for the deduction, regardless of when an investor’s existing approval was granted.
This differs slightly from a scheme like the NOR Scheme, which closed to new applicants without a pre-announced end date baked into the original legislation. AITD, by contrast, always had a defined lifespan, and its lapse in 2020 reflected the government’s periodic reassessment of which start-up funding incentives remained the most effective use of tax relief.
AITD Scheme Example (Historical)
An approved angel investor put S$200,000 into a qualifying Singapore fintech start-up in June 2018, well within the scheme’s window. Under AITD, she was able to claim a tax deduction of 50% of that amount, or S$100,000, against her taxable income, subject to the scheme’s overall deduction cap and the requirement to hold the investment for at least two years. Because the investment was made before the 31 March 2020 cut-off, her ability to claim this deduction is unaffected by the scheme’s later lapse, as long as she continues to meet the holding period and other original conditions.
Why AITD Mattered While It Was Available
- Reduced the after-tax cost of angel investing. The 50% deduction meaningfully softened the downside for investors backing high-risk, early-stage companies.
- Encouraged domestic angel capital. It gave Singapore-based investors a direct tax incentive to fund local start-ups rather than only overseas opportunities.
- Complemented Singapore’s start-up ecosystem push. It ran alongside other government efforts, such as grants and co-investment schemes, aimed at building up Singapore’s early-stage funding landscape.
- Rewarded genuine risk-taking. The requirement for a minimum holding period discouraged short-term, tax-driven investing rather than genuine early-stage backing.
Risks and Limitations
- No longer available. Angel investors funding Singapore start-ups today cannot access this specific deduction, regardless of how closely their situation resembles a pre-2020 qualifying investment.
- Approval and qualifying conditions were strict. Even during the scheme’s life, not every investor or every start-up investment automatically qualified.
- Minimum holding period still applies to legacy claims. Investors relying on the deduction for pre-2020 investments must continue meeting original conditions, or risk clawback of the benefit already claimed.
- Confusing name recognition. Because AITD is sometimes still referenced in older articles and startup community discussions, new investors can mistakenly believe it remains available.

The Bottom Line
The AITD Scheme was a time-limited incentive that closed by design in 2020, and no new investments qualify for it today. Investors backing Singapore start-ups now should look at the current landscape of grants, co-investment programmes, and other tax incentives rather than assuming this specific deduction is still on offer.
