Tonnage Tax for Shipping explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
1. What is Tonnage Tax?
Tonnage Tax is a special optional tax regime available to Indian shipping companies — both domestic trade shipping and international shipping. Instead of paying income tax based on actual profits, a qualifying shipping company pays tax based on the notional income derived from the tonnage (carrying capacity) of its ships. This provides certainty, simplicity, and often a lower effective tax burden for shipping businesses with high capital costs.
2. Who Can Opt for Tonnage Tax?
The Tonnage Tax scheme under Sections 135A-135F of ITA 2025 is available to:
- Indian company engaged in the business of operating qualifying ships
- The company must be resident in India
- Ships must be qualifying ships — registered under Merchant Shipping Act, 1958 or flagged in another country but operated by the Indian company
- Option is exercised within 3 months of the start of the Tax Year (or from commencement of business)
- Once opted, the company must continue for at least 10 years — early exit attracts penalties
3. Tonnage Income Computation
Tonnage income is computed based on the net tonnage (NT) of each qualifying ship per day:
| Daily Tonnage (Net Tonnes) | Notional Income per 100 NT per day |
|---|---|
| Up to 1,000 NT | Rs 46 |
| 1,001 to 10,000 NT | Rs 35 |
| 10,001 to 25,000 NT | Rs 28 |
| Above 25,000 NT | Rs 19 |
Annual tonnage income = Daily NT income × 365 days. Tax at normal corporate rate (22-25%) applies on this computed income — regardless of actual profit or loss.
4. Benefits of Tonnage Tax
- Certainty — tax liability known at the start of the year
- Lower effective tax when actual shipping profits are high
- No disallowances — depreciation, interest, operating costs are all irrelevant
- Dividend distributed from tonnage tax profits is not subject to additional DDT
- MAT provisions do not apply to tonnage tax companies for qualifying shipping income
5. Non-Qualifying Income
Only income from qualifying ship operations falls under tonnage tax. Other income of the shipping company — interest, rental, non-ship trading activities — is taxed normally under the Income Tax Act, 2025. Separate books of accounts must be maintained for tonnage and non-tonnage income.
6. Exit Provisions
If a company opts out of the tonnage tax scheme before completing 10 years, the deductions and benefits enjoyed during the tonnage scheme period are withdrawn — and the company is assessed on actual profits for those years as if it had not opted for tonnage tax. This clawback provision makes the tonnage scheme a long-term commitment.

What is tonnage tax?
Tonnage tax is a special optional tax regime for Indian shipping companies where tax is computed on a notional income based on the carrying capacity (tonnage) of ships — not on actual profits. The notional income rate ranges from Rs 46 per 100 net tonnes/day (for ships up to 1,000 NT) to Rs 19 per 100 NT/day (for ships above 25,000 NT). Corporate tax at normal rates applies on this computed notional income. Once opted, the regime must continue for 10 years.
Who qualifies for the tonnage tax scheme?
The scheme is available to Indian resident companies operating qualifying ships registered under the Merchant Shipping Act or flagged in other countries but operated by the Indian company. The option must be exercised within 3 months of the Tax Year start. The 10-year commitment clause is significant — early exit results in all tonnage benefits being withdrawn and the company being assessed on actual profits for the entire period.
Over 90% of compliance penalties in India arise from missed due dates — timely handling can save businesses thousands of rupees each year.
