Double Tax Deduction for Internationalisation (DTDi)

What is Double Tax Deduction for Internationalisation?

The Double Tax Deduction for Internationalisation (DTDi) is Singapore’s primary tax incentive for overseas expansion, administered by Enterprise Singapore and assessed by IRAS. Unlike cash grants like MRA or EDG, DTDi provides a 200% tax deduction on qualifying expenses — meaning every S$1 spent on overseas market development reduces your taxable income by S$2. The automatic deduction cap is S$400,000 per Year of Assessment (from YA 2027, raised from S$150,000 under Budget 2026).

DTDi Quick Answer

Use DTDi when you want a 200% tax deduction for overseas market development expenses instead of reimbursement. Use MRA when you need grant support for a defined overseas expansion project, and use DTDi when the cost is better handled through annual IRAS tax filing.

Budget 2026 Update: The automatic deduction cap has been raised from S$150,000 to S$400,000 per Year of Assessment (from YA 2027). Overseas development trips and investment study trips have been added to the automatic categories. See DTDi Budget 2026 Changes for details.

Who is DTDi for?

• Companies planning to expand into overseas markets
• Businesses seeking investment development opportunities abroad
• Trading companies promoting goods internationally
• Service providers establishing overseas market presence
• Companies conducting market research and feasibility studies overseas

Eligibility

To be eligible for DTDi, your company must meet the following criteria:

• Business entity resides in Singapore
• Primary purpose is trading, providing services, or investing
• Planning to expand internationally or develop overseas business activities
• Incurring qualifying expenses for market development or investment activities

Types of Qualifying Activities

DTDi supports the following categories of overseas market development activities:

1. Overseas Trade Missions - Business travel for market development
2. Overseas Market Development Trips - Direct market exposure and networking
3. Overseas Investment Study Trips - Feasibility studies for investment
4. Overseas Marketing Activities - Promotional campaigns and brand building
5. Participation in Trade Exhibitions - Booth costs and participation fees
6. Advertising in Approved Trade Publications - Trade journal advertising
7. Overseas Trade Office Setup - Salaries and office rental for staff posted abroad (from 1 Jan 2026)
8. Professional Consultancy - Market research and business consulting
9. Business Networking Events - Third-party arranged networking programs

How DTDi Works

1. Automatic DTDi (No Prior Approval)

You can automatically claim 200% tax deduction on the first S$400,000 of eligible expenses per year of assessment (as of Budget 2026, from YA 2027; previously S$150,000) for approved activity categories without seeking EnterpriseSG’s approval.

Automatic categories:

• Overseas market development trips/missions
• Overseas investment study trips/missions
• Overseas trade missions
• Trade fair participation
• Trade publication advertising
• Professional consultancy services
• And others approved by EnterpriseSG

2. Approval-Required DTDi

Expenses exceeding S$400,000 per year (as of Budget 2026, from YA 2027; previously S$150,000) or in categories outside the automatic areas require prior EnterpriseSG approval.

Examples:

• Fees for securing speaking spots at overseas conferences
• Logistic costs for transporting materials/samples
• Third-party consultant fees for arranging business events

3. Tax Deduction Calculation

• Tax deductible amount: 200% of qualifying expenses (not 100%)
• Automatic limit: S$400,000 per year of assessment (from YA 2027; previously S$150,000)
• Meaning: If you spend S$100,000, you can deduct S$200,000 from taxable income
• Benefit: Reduces taxable profits and resulting corporate tax liability

Tax Savings Worked Example

Here is a worked example showing how DTDi translates to actual tax savings:

Without DTDi, the same S$100,000 expenses would yield only S$17,000 in regular tax deduction (at 17%). With DTDi, you save an additional S$17,000 in taxes — effectively recovering 34% of your overseas expansion costs through tax savings.

Key point: DTDi is NOT a cash grant — the benefit comes as reduced corporate tax liability. Companies with no taxable income will not benefit from DTDi. Consider MRA (cash reimbursement) instead.

Common Pitfalls to Avoid

• Not understanding it’s a tax deduction, not a cash grant - Benefit realized through reduced tax liability, not direct funding
• Exceeding S$400,000 without approval (from YA 2027; previously S$150,000) - Must obtain pre-approval for amounts exceeding the automatic limit
• Mixing domestic and overseas expenses - Only overseas market activities qualify
• Inadequate documentation - Keep detailed records of all qualifying expenses
• Claiming after tax return deadline - File within the allowed time frame with EnterpriseSG

Important Notes

• DTDi is available to all eligible companies - no SME-only restriction
• Immediate benefit through tax savings - Reduce tax liability in the year expenses are incurred
• Flexible activities - Wide range of market development activities covered
• Multiple years - Can claim DTDi across multiple years for ongoing international expansion
• No grant application - Claim automatically on tax return for automatic activities

Frequently Asked Questions

Is DTDi a cash grant?

No. DTDi is a tax deduction scheme. The benefit is realized as reduced corporate tax liability, not as direct funding.

Can I claim multiple years of DTDi?

Yes. If your company conducts ongoing overseas market development, you can claim DTDi across multiple years of assessment. Each year has a separate S$400,000 automatic limit (from YA 2027; previously S$150,000).

What’s the difference between automatic and approval-required activities?

Automatic activities up to S$400,000 need no approval — claim on your tax return. Approval-required activities (those exceeding S$400,000 or special categories) need EnterpriseSG clearance before you incur expenses. (Threshold raised from S$150,000 as of Budget 2026, from YA 2027.)

Can startup companies apply for DTDi?

Yes, provided they meet the eligibility criteria (Singapore-based business with primary purpose of trading/services and planning international expansion).

Do I need to apply separately or just claim on tax return?

For automatic activities, no separate application needed - just claim on your annual tax return. For approval-required activities, apply to EnterpriseSG before incurring expenses.

When should I NOT use DTDi?

DTDi may not be suitable if:

• Your company has no taxable income (the deduction has no value — consider MRA for cash reimbursement instead)
• Your overseas expenses are very small (under S$5,000) — the record-keeping effort may outweigh the tax benefit
• You need upfront cash support (DTDi only reduces future tax liability, it does not reimburse costs)
• Your activities are purely domestic — only overseas market development qualifies

Can I claim both DTDi and MRA for the same overseas expansion?

No. You cannot claim DTDi and MRA for the same expenses. However, you can use DTDi for some expenses and MRA for others, as long as there is no overlap. For example, use MRA for your overseas marketing consultant and DTDi for your business trips.

How is DTDi different from MRA?

Both support overseas expansion but work differently:

• DTDi = Tax deduction (200%), no application needed for first S$400K, no SME restriction, benefit is reduced tax bill
• MRA = Cash reimbursement (70%), requires BGP application, SME-only, benefit is direct cash back Use DTDi if you have taxable income and want simplicity. Use MRA if you need cash reimbursement or are a startup without taxable income.
