Singapore businesses can claim an enhanced 400% tax deduction on up to S$50,000 of qualifying artificial intelligence (AI) expenditure for Year of Assessment (YA) 2027 and YA 2028 under the expanded Enterprise Innovation Scheme (EIS). The Inland Revenue Authority of Singapore (IRAS) confirms this change under Budget 2026. Qualifying expenditure may include AI-system subscriptions or licences and defined business services supporting development, deployment, operation or maintenance of AI, rather than every item marketed as ‘AI technology’.
The most important distinction is between a deduction and a payment: a 400% tax deduction reduces the amount of income subject to tax under the scheme. It is not a S$200,000 cash grant simply because the maximum qualifying cost is S$50,000. The new AI category is also excluded from EIS’s separate 20% cash-conversion option. Government-funded or subsidised portions, hardware such as servers and non-qualifying mixed project expenditure must not be counted in the enhanced AI claim.
This practical guide is for local companies, sole proprietors, partnerships, technology teams, accountants and school or service-business owners considering AI adoption. It explains eligible costs, how to build evidence before signing contracts, the difference between YA and invoice date, the effect on actual tax payable and how to avoid mistaken claims or software-vendor guarantees.
Updated 4 November 2026. This independent eduKateSG guide explains the published IRAS Enterprise Innovation Scheme, not individual tax advice, an approved claim or a Government cash grant. For actual expenditure and tax filings, use the current IRAS rules and qualified advisers as appropriate.
The YA2027 changes at a glance
- AI adoption becomes a qualifying EIS category for YA 2027 and YA 2028 only under the currently published Budget 2026 expansion.
- Eligible businesses can receive a 400% deduction on up to S$50,000 of qualifying AI expenditure in each relevant YA.
- Where expenditure already qualifies under ordinary Section 14 business expenses, the 400% comprises 100% base plus 300% enhanced deduction on the first S$50,000.
- Where otherwise capital in nature, specified qualifying AI expenditure can still receive a 400% EIS deduction subject to the statutory conditions.
- Qualifying AI spending covers subscriptions or licences for AI systems and defined subscriptions, acquisitions or licences of AI business services.
- Qualifying AI services may include development, deployment, operations, maintenance, AI system engineering, data analytics, consultancy and relevant training.
- Physical infrastructure and hardware, including servers, storage devices and computing equipment, are excluded from the new AI enhanced-deduction definition.
- Amounts subsidised by a Government grant or subsidy are excluded; only eligible net costs should form the claim.
- The new AI category cannot be converted into the separate EIS cash payout, although other eligible EIS activities may qualify for cash conversion under their own rules.
- Business activity in Singapore and incurring expenditure in the relevant YA basis period are core eligibility conditions; claims must be supported by accurate records.
What a 400% deduction does not mean
- 400% does not mean IRAS pays a business four times its invoice amount in cash.
- An AI-enhanced laptop or GPU server does not automatically qualify for this new specific AI expenditure deduction.
- Not every software subscription is an AI system or a service connected to adopting AI for a genuine trade or business.
- Companies with no chargeable income may not enjoy the same immediate tax saving as profitable companies; deduction is not an unconditional refund.
- The 20% EIS cash-payout option is specifically excluded for the new AI category, despite being available on other eligible EIS activities.
- Government grant-funded costs cannot be claimed again as qualifying AI expenditure, and mixed contracts need reasonable apportionment.
- The year of assessment and the accounting basis period should be confirmed with IRAS instead of assuming every invoice paid in calendar 2027 belongs to YA 2027.

The examples below are hypothetical, and no example is a promise about an individual business’s allowable deduction or tax saving. Evidence of business use, correctly allocated expenditure and the year of assessment are essential.
1. The change is for YA 2027 and YA 2028
IRAS’s Enterprise Innovation Scheme ran before 2027, supporting activities such as research and development, intellectual property and training. Budget 2026 added a dedicated AI adoption category for two years of assessment: YA 2027 and YA 2028. This is not a permanent promise that every future AI expense will receive 400% treatment. A business should first identify its accounting period and the relevant tax year, because a YA normally relates to a preceding basis period. The scheme also does not force firms to buy AI products; it provides a tax incentive where a purchase or service genuinely supports business operations and meets conditions.
Illustrative business example
Scenario: A company purchasing AI software in late 2026 assumes the tax claim necessarily belongs to the year printed on the invoice rather than its relevant basis period.
What to check or do
Map the expense to the correct YA and seek an accountant’s advice where the business has a non-calendar financial year.
2. What a 400% deduction means in plain English
A deduction lowers taxable income; it is not a payout equal to the deducted amount. For example, if S$10,000 of expenditure qualifies, the 400% rule could allow a total S$40,000 tax deduction instead of the normal S$10,000 business deduction where applicable. That does not mean receiving S$40,000 in the company’s bank account. The actual tax effect depends on chargeable income, statutory deductions, prevailing tax rate and other relevant reliefs. A firm already making a loss may not receive the immediate tax reduction predicted by a simple illustration.
Illustrative business example
Scenario: A vendor promises a school-business owner that paying a S$10,000 AI licence fee generates an automatic S$40,000 Government grant.
What to check or do
That misunderstands a deduction. Request a proper tax computation rather than accepting vendor marketing about a guaranteed cash return.
3. Why the cap is S$50,000 of qualifying spend
The special AI tax deduction covers the first S$50,000 of qualifying AI expenditure in a relevant YA. A 400% rate applied to the maximum qualifying expenditure can give a deduction amount up to S$200,000, depending on the particular treatment and costs. It does not give S$200,000 to every firm adopting AI, and does not allow an organisation to multiply an arbitrary software budget by four without regard to qualification. Where expenditure above S$50,000 is allowable as an ordinary Section 14 business expense, IRAS says it can continue at the usual 100% deduction subject to law.
Illustrative business example
Scenario: A company budgets S$200,000 for AI and assumes the entire amount will enjoy the enhanced 400% rate because the theoretical maximum deduction is S$200,000.
What to check or do
The maximum qualifying expenditure for the enhanced rate is only S$50,000 per relevant YA. Separate the eligible portion and the treatment of the balance.
4. AI systems and ordinary software are not identical
IRAS defines an AI system as a machine-based system that infers from inputs to produce outputs such as predictions, recommendations, content or decisions, which may influence a digital or physical environment. Examples of relevant capabilities include natural language processing, reasoning, computer vision, automated planning and multimodal tasks. A simple spreadsheet performing a fixed multiplication formula is not automatically an AI system. Equally, an AI system might be embedded inside a larger software platform and only part of the fee may relate to genuine AI use. The legal classification depends on the actual function, not the sales brochure’s label.
Illustrative business example
Scenario: A vendor rebrands a conventional data-entry product as ‘AI powered’ without demonstrating the relevant inference or business function.
What to check or do
Document the system’s real capability and ask whether the contract specifies an identifiable qualifying AI component.
5. Subscriptions and licensed AI tools may qualify
The new definition covers subscriptions to or licences of qualifying AI systems supplied by another person. In business terms, this can include an AI service supporting operational forecasting, permitted customer communications, image or language processing, or other genuine work where the statutory tests are met. A monthly subscription can be easier to document than a sprawling custom project, but only the portion qualifying under IRAS rules should be considered. A personal entertainment chatbot used outside the business cannot simply be included because the owner pays with a corporate credit card.
Illustrative business example
Scenario: A tuition operator uses a licensed AI tool to help organise teaching-material workflow but also maintains unrelated family subscriptions under the same account.
What to check or do
Separate business use from personal costs and keep the supplier invoice, licence terms and evidence of actual operational use.
6. The scheme also covers AI adoption services
IRAS includes defined AI business services supporting an organisation’s development, deployment, operation or maintenance of an AI system. These can include system development, consultancy and strategy, data and analytics, engineering, compliance work and system-related training. The important link is to the actual AI system and the organisation’s trade or business. A consultant’s entire advisory fee does not automatically qualify if the project contains unrelated business strategy, general staffing or website redesign. Procurement should identify deliverables and responsibilities so that the qualifying component can be demonstrated.
Illustrative business example
Scenario: A consultancy quotes a S$30,000 package covering AI deployment, ordinary website maintenance and unrelated branding services.
What to check or do
The AI-related portion requires evidence and may need reasonable apportionment. Ask for line items and a clear scope of work.
7. Servers and other physical hardware are excluded
The new AI qualifying expenditure definition explicitly excludes physical infrastructure or hardware such as servers, storage devices and computing equipment. This is an important limit when firms plan data centres, GPU-based workstations or on-premises servers for AI development. Such spending may have other tax treatment under ordinary business or capital allowance provisions, but that is a separate question. A business should not classify the entire cost of a new server as an AI subscription just because it will run machine-learning software. The rule is focused on qualifying AI systems and business services.
Illustrative business example
Scenario: A manufacturer purchases a powerful computer and an AI inspection-software licence on the same invoice and wants to claim the entire amount under the 400% AI category.
What to check or do
Separate the hardware from the eligible software or service costs and obtain the appropriate tax treatment for each.
8. Government subsidies reduce the qualifying amount
IRAS states that expenditure subsidised by a grant or subsidy from the Government does not qualify for the AI enhanced deduction. This prevents double counting public support for the same cost. More generally, the EIS page explains that eligible expenditure for benefits is measured net of applicable Government grants or subsidies. If an AI project contains both publicly funded and business-funded components, accurate allocation matters. Firms should understand the grant terms and accounting records before deciding how much expenditure remains eligible for tax deduction.
Illustrative business example
Scenario: A company buys a S$20,000 qualifying software package with half the fee covered by a Government grant and assumes it can claim 400% on the entire S$20,000.
What to check or do
The subsidised portion must not be claimed again under the new AI category. Reconcile grant and invoice evidence before filing.
9. Mixed contracts need reasonable apportionment
Many enterprise technology purchases bundle AI services with normal software, hardware, integration, staff training and consulting. IRAS requires mixed qualifying and non-qualifying expenditure to be apportioned so that only the eligible AI portion receives enhanced deduction. Where a vendor cannot provide an explicit breakdown despite reasonable efforts, the business should use a defensible and documented basis for apportionment. Splitting an invoice without evidence solely to maximise a tax claim is unsafe and could attract questions during an audit. The company’s record should explain what was purchased and how cost allocations were derived.
Illustrative business example
Scenario: A supplier bills one flat fee for CRM software, an embedded AI assistant and a separate office server with no line items.
What to check or do
Seek a cost breakdown first, and if necessary prepare a reasonable evidence-backed apportionment following IRAS guidance.
10. Active business operations in Singapore matter
IRAS’s enhanced-deduction eligibility includes carrying on active business operations in Singapore and incurring qualifying expenditure during the basis period of the relevant YA. Business entities eligible in principle include companies, partnerships and sole proprietorships that meet the actual conditions. The scheme is not a personal income-tax relief for someone experimenting with AI at home or a consumer discount on subscriptions. A business headquartered abroad also should not assume it qualifies without the relevant Singapore operations and tax requirements.
Illustrative business example
Scenario: A student buys a personal AI tool and believes the 400% business deduction can be claimed on an ordinary individual income tax return without operating a business.
What to check or do
That is not the EIS eligibility basis. Only make claims grounded in qualifying commercial activity and current tax rules.
11. Cash conversion is not available for AI adoption
The established EIS allows some eligible businesses to convert up to S$100,000 of spending on other qualifying innovation activities into a cash payout of 20%, up to S$20,000 per YA. IRAS specifically excludes the new AI adoption category from this option. This distinction prevents a common error: advertisements that promise a S$10,000 or S$20,000 cash refund for buying a particular chatbot may be conflating different parts of the scheme. Where other EIS activities genuinely qualify, their cash-conversion rules remain separate and must be checked independently.
Illustrative business example
Scenario: A startup is told its AI licence can generate a 20% cash reimbursement because an older EIS brochure describes cash conversion.
What to check or do
The special AI deduction is explicitly not eligible for that option. Distinguish tax savings from cash payouts and read the new schedule.
12. The usual deductions and enhanced deductions differ
For qualifying AI expenditure already deductible as ordinary business expense under Section 14, the new arrangement adds an enhanced component of 300% to produce a total 400% deduction on eligible spending within the S$50,000 cap. Where qualifying expenditure would otherwise be capital and not ordinarily deductible, IRAS provides a specific 400% deduction under the new provision. The treatment beyond the cap is different depending on which underlying deduction, if any, applies. Accountants should avoid double-counting the ordinary 100% and full 400% amount in the tax computation.
Illustrative business example
Scenario: A company records its S$10,000 AI software expense in profit and loss, then adds a separate S$40,000 deduction on top of the original ordinary S$10,000 without checking the required total.
What to check or do
Identify whether the base deduction is already counted. The intended total is 400% under the relevant rule, not an automatic 500%.
13. No taxable profit means a different immediate benefit
Tax deductions lower taxable income, so their immediate financial value depends on the business’s actual tax computation. A startup making losses may have a deduction that affects its tax attributes rather than producing a cash payment in the claim year, subject to the usual loss and carry-forward rules. Conversely, a profitable company may reduce its current chargeable income, with tax savings depending on its effective rate, other exemptions and the availability of relief. This is why a vendor cannot promise every purchaser the same cash return from an AI subscription.
Illustrative business example
Scenario: A loss-making business sees a theoretical S$6,800 tax saving illustration based on a S$40,000 deduction at 17% and assumes IRAS will pay that money into its bank account.
What to check or do
A deduction does not create that direct grant. Obtain a complete tax computation based on the actual business’s circumstances.
14. Evidence and governance should be part of procurement
A sensible AI purchase begins with a concrete business task, such as improving the accuracy of document search or scheduling. The company should ask whether the tool performs reliably, protects customer data and can be used within applicable contracts and law. Tax incentives can make a qualifying investment more attractive but should not be the only justification for buying it. Records should include invoices, agreements, proof of business use, grant offsets and any reasonable cost allocation. AI systems can also make mistakes, so a buyer needs a plan for human verification of consequential outputs.
Illustrative business example
Scenario: A clinic administration team wants to buy an AI transcription product only because the quotation claims a 400% tax deduction, without reviewing patient privacy.
What to check or do
The expected tax treatment cannot replace data security and professional obligations. Assess real operating needs first and document the purchase carefully.
15. How and when a firm claims the EIS deduction
IRAS explains that enhanced EIS deductions are declared through the relevant income-tax return. Companies use the Enterprise Innovation Scheme section of the corporate return, while sole proprietors and partnerships follow their individual or partnership filing instructions and any enhanced-deduction records submission. Normal filing deadlines and documentation obligations apply. YA 2027 or YA 2028 should be determined using the proper basis period, not simply the invoice’s year of payment. Unsupported claims, deliberate omissions or duplicate deduction and cash-conversion treatment can lead to correction or penalties.
Illustrative business example
Scenario: A partnership buys an AI service and thinks it can claim a Government cash payout at any date without filing an income-tax return.
What to check or do
The new AI activity is a deduction, not a cash option. Follow the applicable tax filing process and preserve supporting evidence.
16. A practical AI investment checklist for YA 2027
Before signing an AI contract, identify the precise business problem and expected improvement. Check whether the item is an AI system or qualifying AI business service under IRAS’s definition. Separate hardware, ordinary services and any grant-funded cost. Review the relevant basis period and the S$50,000 qualifying cap, then estimate the real benefit using the company’s taxable income rather than the supplier’s headline arithmetic. Preserve documentation and review privacy, security and quality risks before deployment. If the treatment is uncertain, seek qualified tax advice or clarification from IRAS rather than making a large financial commitment based on guesswork.
Illustrative business example
Scenario: A small business is comparing a S$12,000 AI subscription with a S$25,000 hardware-heavy solution and wants to choose the one with the highest advertised relief.
What to check or do
Compare the actual eligible components, operational value and total cost. A deduction should support a sound business decision, not substitute for one.
Tax deduction versus cash payout

Conclusion: buy AI for genuine value, then verify the tax benefit
The new 400% AI tax deduction encourages businesses to adopt useful technology but does not mean every software purchase is subsidised or free. The exact qualifying system, cost, business function and Year of Assessment matter. A responsible purchase should deliver operational value even before the tax incentive is considered.
Document what the company actually bought, keep hardware and Government-funded portions separate, protect customer data and use a proper tax computation. Clear accounting prevents an attractive headline from becoming an expensive misunderstanding.
