DTDi Singapore · Tax incentive
The DTDi playbook.
The Double Tax Deduction for Internationalisation (DTDi) lets Singapore-tax-resident companies claim 200% tax deduction on qualifying overseas expansion expenses. Automatic up to S$400k from YA 2027, no pre-approval needed. The smartest way to lower the tax bill on your overseas push — pairs naturally with the MRA cash grant.
DTDi is a tax incentive, not a cash grant.
You don't receive cash. You claim 200% deduction on qualifying expenses, which reduces your taxable income. At Singapore's 17% headline corporate tax rate, that's roughly 17 cents back per S$1 of qualifying expense. For cash subsidy on the same overseas expansion, pair this with the MRA Grant.
What is DTDi Singapore?
DTDi is a long-running EnterpriseSG tax incentive that allows qualifying Singapore-tax-resident businesses to deduct 200% of qualifying expenseson overseas market expansion when computing taxable income. At Singapore's 17% corporate tax rate, every S$1 of qualifying spend effectively reduces tax by ~17 cents.
It is administered by EnterpriseSG (project approval where required) and IRAS (tax claim assessment). The two work together: ESG issues a Letter of Support for application-based claims, IRAS adjudicates the actual tax computation.
The Automatic DTDi (this changed in YA 2027)
From Year of Assessment 2027, the automatic claim cap was raised from S$150,000 to S$400,000 per company per year. Within this cap, for most activities, you simply claim the 200% deduction directly when filing your IRAS return — no application to EnterpriseSG required.
Activities NOT covered by Automatic DTDi (must apply via ESIMS portal regardless of amount):
- Overseas Trade Office — including overseas posting salaries (subsumed under this from 1 Jan 2026)
- E-Commerce Campaigns
For all other qualifying activities: keep your documentation, claim the 200% via your annual tax filing, and be ready to substantiate if IRAS asks.
Eligibility
- Business entity resident in Singapore
- Primary purpose is to promote the trade of goods or the provision of services
- The internationalisation project must serve one of four key objectives:
- Promote the company's new products / services to new target markets
- Identify new customers in target markets for existing products / services
- Promote new products / services to existing customers
- Promote existing products / services to existing markets to grow market share
- For application-based claims (above S$400k auto cap, or Overseas Trade Office / E-Commerce Campaigns): apply on the DTDi portal BEFORE project starts. Retrospective claims may be rejected.
- Businesses with discretionary incentives (ITA Sections 13A, 13E, 13P, 13S, 43C…) may qualify case-by-case provided global headquarters are in Singapore.
Qualifying activities
DTDi covers activities across the overseas growth lifecycle. EnterpriseSG maintains the definitive list of qualifying activities and expenditure. Common categories:
- Overseas market promotion — overseas trade fairs, in-market promotions, product launches, business missions, approved local trade publications, approved virtual trade fairs
- Overseas business development — overseas study trips, in-market activities, identification of overseas partners and distributors
- Overseas market set-up — Overseas Trade Office costs (including Singaporean / Singapore PR staff salaries posted overseas from 1 Jan 2026), set-up costs in target market
- Investment development — supportable activities related to overseas investment and joint ventures
- Standards and certifications — only approved certifications on the EnterpriseSG list
- E-Commerce Campaigns — application required (not under Automatic DTDi)
The DTDi × MRA stacking play (this is the move)
DTDi and the MRA Grant were designed to work together. Two different mechanisms, two different cost segments:
- MRA reimburses CASH — 70% of qualifying overseas market expansion costs (capped S$100k per market). You pay vendor, MRA refunds 70%.
- DTDi reduces TAX — on the remaining 30% out-of-pocket (plus other qualifying spend MRA didn't cover). 200% deduction on that residual = lower taxable income = lower tax bill.
Worked example: You spend S$50,000 on a Vietnam market entry. MRA reimburses S$35,000 cash (70%). You're out-of-pocket S$15,000. DTDi gives you 200% deduction on that S$15k = S$30k taken off taxable income. At 17% tax, that's S$5,100 less corporate tax. Total cost to your business: S$50k − S$35k (MRA) − S$5.1k (DTDi tax savings) = S$9,900. Stacking is the move.
How to claim (decision tree)
- Total qualifying expense this year ≤ S$400k AND not Overseas Trade Office / E-Commerce Campaign?
→ Claim the 200% deduction directly via your IRAS tax filing. Keep documentation. Done. No EnterpriseSG involvement needed. - Expense above S$400k OR activity is Overseas Trade Office / E-Commerce Campaign?
→ Apply via the EnterpriseSG ESIMS portal (Corppass login) BEFORE the project starts. Approved → run project → submit Evaluation Form → ESG issues Letter of Support → attach to IRAS tax return.

How an AI Consultant in Singapore makes DTDi work
DTDi looks straightforward — until you scope a complex overseas expansion. Most Singapore SMEs leave money on the table by mis-classifying activities, missing documentation requirements, or failing to coordinate the MRA + DTDi sequence properly. An AI consultant who has scoped MRA / EDG / DTDi stacks together can design the project so you maximise both cash subsidy AND tax savings. Talk to me about your DTDi + MRA strategy →

Frequently asked questions
DTDi (Double Tax Deduction for Internationalisation) is an EnterpriseSG tax incentive — NOT a cash grant — that lets Singapore-tax-resident companies claim 200% tax deduction on qualifying expenses for overseas market expansion. It reduces your taxable income, which lowers your corporate tax bill. The effective benefit at Singapore's 17% headline rate is roughly 17 cents back per S$1 of qualifying expense.
MRA is a CASH grant — EnterpriseSG reimburses up to 70% of qualifying overseas expansion costs (capped S$100k per market). DTDi is a TAX deduction — you spend the money, deduct it 200% from taxable income, pay less corporate tax. Many Singapore SMEs going overseas use BOTH: MRA covers the cash subsidy upfront; DTDi reduces the tax on the remaining out-of-pocket portion.
From Year of Assessment (YA) 2027, you can claim 200% tax deduction on the first S$400,000 of eligible expenses per company per year for most activities (excluding Overseas Trade Office and E-Commerce Campaigns) — WITHOUT pre-approval from EnterpriseSG. Just file via IRAS. Previously the cap was S$150,000. Above S$400k OR for excluded activities, you must apply via the DTDi portal before starting the project.
Business entities resident in Singapore whose primary purpose is to promote the trade of goods or provision of services. Businesses enjoying discretionary incentives (under specific Income Tax Act sections) may also qualify case-by-case with EnterpriseSG or STB approval, provided their global headquarters are in Singapore. The project must have a clear internationalisation objective — new products, new markets, new customers, or market share gain.
Qualifying activities span the overseas expansion lifecycle: overseas market promotion (trade fairs, in-market activations), business development (study trips, market surveys, identification of partners), market set-up (overseas trade office costs, including Singaporean staff salaries posted overseas from 1 Jan 2026), and investment development. See EnterpriseSG's full qualifying activities + expenditure list (linked below) for the definitive list.
Two paths: (1) AUTOMATIC: For qualifying activities and expenses within the S$400k cap, simply claim the 200% deduction directly when filing your annual income tax return with IRAS. Keep documentation (invoices, receipts, trip itinerary, list of companies met) for IRAS review. (2) APPLICATION-BASED: For expenses above S$400k OR for Overseas Trade Office / E-Commerce Campaigns, apply via the EnterpriseSG ESIMS portal BEFORE starting the project. After project completion, submit Evaluation Form → ESG issues Letter of Support → attach to your IRAS tax return.
Yes. Common stack for Singapore SMEs going overseas: MRA (cash grant, 70% of qualifying costs) + DTDi (200% tax deduction on the remaining 30% out-of-pocket) + EDG (custom capability uplift in parallel). These don't double-claim — MRA reimburses CASH; DTDi reduces TAX on the post-MRA OOP; EDG funds different cost lines entirely. Net cost to your business can be very low.
