Most Singapore SME owners hear “400% tax deduction” and quietly file it under too good to be true<\/em> or too complicated to bother<\/em>. It’s neither. The Enterprise Innovation Scheme (EIS) is a real, IRAS-administered incentive, and from 2027 it specifically rewards spending on AI — the kind of work an AI consultancy Singapore SMEs trust would scope for you.<\/p>\n

But the headline number gets thrown around carelessly, and an owner who acts on the hype version can end up disappointed. So let’s do the opposite: take a realistic project — a S$100,000 AI telemarketing system — and work through exactly what the scheme does and doesn’t save, in plain figures.<\/p>\n

What the EIS actually is<\/h2>\n

The EIS is Singapore’s flagship innovation tax incentive, available from YA 2024 to YA 2028. In Budget 2026, the government added AI expenditure as a new qualifying activity<\/strong> for YA 2027 and YA 2028<\/strong>, letting businesses claim a 400% tax deduction on up to S$50,000 of qualifying AI spending per year<\/strong>.<\/p>\n

Two things to fix in your mind before any numbers, because they’re where most misunderstandings start:<\/p>\n

First, it is a tax deduction, not a cash grant<\/strong>. It reduces your taxable income; it doesn’t post money into your bank account. The benefit only materialises if your business is profitable enough to have tax to offset. A loss-making year gets nothing from it. (Unlike some other EIS categories, the AI category has no cash-payout option at all.)<\/p>\n

Second, the S$50,000 cap is per year<\/strong>. The “400%” applies only to the first S$50,000 of qualifying AI spend in a Year of Assessment — not to your whole project. That single detail changes the math on a six-figure build, as you’ll see.<\/p>\n

The scenario: a S$100,000 AI telemarketing centre<\/h2>\n

Say an SME engages us to build an AI-powered telemarketing operation: AI voice agents that call and qualify leads, an automated follow-up system, and integration into the company’s CRM so every conversation is logged and scored. Total project cost: S$100,000<\/strong>.<\/p>\n

To keep the example clean, assume the company is profitable, taxed at the standard 17%<\/strong> corporate rate, and that the spend qualifies as AI expenditure once IRAS finalises the criteria (more on that caveat at the end).<\/p>\n

Here’s how the same S$100,000 is treated with and without the scheme.<\/p>\n\n\n\n\n\n\n\n\n\n
<\/th>\nWithout EIS<\/th>\nWith EIS (AI category)<\/th>\n<\/tr>\n<\/thead>\n
Project cost<\/td>\nS$100,000<\/td>\nS$100,000<\/td>\n<\/tr>\n
First S$50,000 (the cap)<\/td>\nNormal 100% deduction = S$50,000<\/td>\n400% deduction = S$200,000<\/strong><\/td>\n<\/tr>\n
Remaining S$50,000<\/td>\nNormal 100% deduction = S$50,000<\/td>\nNormal 100% deduction = S$50,000<\/td>\n<\/tr>\n
Total tax deduction<\/strong><\/td>\nS$100,000<\/strong><\/td>\nS$250,000<\/strong><\/td>\n<\/tr>\n
Tax reduced (at 17%)<\/strong><\/td>\nS$17,000<\/strong><\/td>\nS$42,500<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

So the picture is this. Any business expense is already deductible, so even without the scheme, spending S$100,000 lowers the tax bill by S$17,000 — your effective cost after tax is about S$83,000<\/strong>.<\/p>\n

The EIS goes further on the first S$50,000: instead of deducting S$50,000, you deduct S$200,000. That extra S$150,000 of deduction, at 17%, is worth S$25,500 in additional tax savings<\/strong>. It brings the effective cost of the project down from S$83,000 to roughly S$57,500<\/strong>.<\/p>\n

In other words, the honest version of the pitch isn’t “the government pays for your AI.” It’s: a S$100,000 AI project effectively costs you closer to S$57,500 once the deduction is applied<\/em> — provided you’re profitable enough to use it.<\/p>\n

The timing trick worth knowing<\/h2>\n

Because the S$50,000 cap resets each year, when<\/em> the money is spent matters. The AI category runs across two Years of Assessment — YA 2027 and YA 2028 — and the cap applies to each.<\/p>\n

If the project is genuinely phased so that S$50,000 of qualifying spend falls in YA 2027 and S$50,000 in YA 2028 — for example, a build delivered in stages, or a subscription paid across two financial years — then the 400% treatment can apply to S$50,000 twice<\/em>:<\/p>\n
