Introduction

A company does not enter tonnage tax merely by operating ships: it must apply to the jurisdictional Joint Commissioner and receive an order on the option. The election normally lasts ten years, subject to conditions and exit rules.

Key takeaways

1

Application and decision

A qualifying company applies to its jurisdictional Joint Commissioner, who decides by written order after the prescribed checks and hearing safeguard.

2

Ten-year option

An approved tonnage-tax option runs for ten years from the date it is exercised unless it ceases earlier under the section.

3

Exit can limit re-entry

Opting out, a specified default or exclusion can bar a fresh option for ten years.

Making the application

A qualifying company may opt for the tonnage tax scheme by applying to the Joint Commissioner having jurisdiction over it, in the prescribed form and manner.

The application must be made within three months of the company's incorporation, or of the date it first becomes a qualifying company - whichever is relevant.

A Unit of an International Financial Services Centre that has availed of the deduction under Section 147 may apply within three months from the date that deduction ceases.

Approval process

On receiving the application, the Joint Commissioner may call for information or documents needed to satisfy himself of the company's eligibility, and must then pass a written order either approving or refusing the option - refusal cannot be ordered without giving the applicant a reasonable opportunity of being heard. A copy of the order is sent to the applicant.

The order must be passed before the expiry of three months from the end of the quarter in which the application was received.

Validity period

Where approval is granted, the tonnage tax scheme applies from the tax year in which the option is exercised, and remains in force for ten years from the date the option was exercised.

When the option ceases to have effect

The option for the tonnage tax scheme ceases to have effect from the tax year in which:

  • The qualifying company ceases to be a qualifying company
  • A default is made in complying with the conditions in Section 232(1) to (20)
  • The company is excluded from the scheme under Section 234 (anti-avoidance exclusion)
  • The company furnishes a written declaration to the Assessing Officer that the scheme should no longer apply to it - after which its shipping income is computed under the Act's other provisions

Renewal and the bar on re-opting

An approved option may be renewed within one year from the end of the tax year in which it ceased to have effect, and the rules governing the original application and approval apply equally to a renewal.

A qualifying company that voluntarily opts out, defaults under Section 232, or is excluded by an order under Section 234(4), is barred from opting for the tonnage tax scheme again for ten years from the date of opting out, the default, or the order.

Step-by-step flow for opting into the tonnage tax scheme under Section 231

  1. 1

    Is the company a qualifying company, and is it within time?

    Apply to the Joint Commissioner with jurisdiction, in the prescribed form and manner. The time limit is three months from incorporation or from first becoming a qualifying company (Section 231(2)). For an IFSC unit that claimed the Section 147 deduction, it is three months from the date that deduction ceases (Section 231(3)).

  2. 2

    Did the company opt out, default under Section 232(1) to (20), or get excluded under Section 234(4) in the last ten years?

    • Yes: It is not eligible to opt for ten years from the date of opting out, default or order (Section 231(12)).
    • No: Go to the next step.
  3. 3

    Joint Commissioner examines eligibility

    The Joint Commissioner may call for information or documents. The order approving or refusing must be passed before three months expire from the end of the quarter in which the application was received (Section 231(6)). A refusal needs a reasonable opportunity of being heard (Section 231(5)).

    • Refused: The scheme does not apply.
    • Approved: Go to the next step.
  4. 4

    Apply the scheme

    The Part applies from the tax year in which the option is exercised. The option stays in force for ten years from the date it is exercised (Section 231(7) and (8)).

  5. 5

    Does a ceasing event occur?

    The option ceases from the tax year in which the company stops being a qualifying company, defaults under Section 232(1) to (20), is excluded under Section 234, or declares in writing to the Assessing Officer that the Part should not apply (Section 231(9)). Renewal is possible within one year from the end of the tax year in which the option ceases (Section 231(10)).

Practical checklist

Do

  • Check qualifying-company status and the application window before submitting the tonnage option.
  • Retain the written approval, tax-year start and ten-year expiry calculation.

Avoid

  • Assume the company can immediately opt in again after a disqualifying exit or exclusion.

Illustrative example

Worked example: application, order date and opting out

Hypothetical facts (illustration only, not a real taxpayer): Tara Marine Ltd. first becomes a qualifying company on 10 June 2026 and applies to the Joint Commissioner on 20 July 2026. The option is approved. In the tax year beginning 1 April 2030 it gives the Assessing Officer a written declaration that the Part should not apply to it. All dates are assumed.

  1. Time limit

    20 July 2026 is within three months of 10 June 2026, so the application is in time under Section 231(2).

  2. Order deadline

    The application was received in the quarter July to September 2026, which ends on 30 September 2026. The order must be passed before three months from that date expire, that is before the end of December 2026.

  3. Start and validity

    The scheme applies from the tax year in which the option is exercised and remains in force for ten years from the date of exercise, unless it ceases earlier.

  4. Opting out

    The declaration ends the option from the tax year beginning 1 April 2030 (Section 231(9)(d)). Under Section 231(12)(a), the company cannot opt again for ten years from the date of opting out.

Outcome

  • The option runs from the year of exercise until it is ended by the declaration in the tax year beginning 1 April 2030.
  • Re-entry is barred for ten years from the date of opting out.

Frequently asked questions

Who approves a company's application to join the tonnage tax scheme?

Ten years from the date the option was exercised, unless it ends earlier due to the company ceasing to be a qualifying company, defaulting on scheme conditions, being excluded for tax avoidance, or voluntarily opting out.

Can a company re-apply immediately after opting out or being excluded?
