Section 234 of the Income-tax Act, 2025 — Avoidance of Tax and Exclusion from the Tonnage Tax Scheme

In plain language

What Section 234 is about

Section 234 of the Income-tax Act, 2025 is an anti-abuse (anti-avoidance) provision that sits inside the special code for shipping companies known as the tonnage tax scheme (Sections 227 to 236). The tonnage tax scheme is a concessional, presumptive way of taxing Indian shipping companies: instead of being taxed on their actual book profits, qualifying shipping companies pay tax on a notional income computed on the net tonnage (carrying capacity) of their ships. This usually results in a very low, predictable tax outgo.

Because the scheme is so beneficial, there is a temptation to shift profits into the tonnage-tax "bucket" (where they are barely taxed) and shift expenses/losses into the normal-tax "bucket" (where they reduce ordinary taxable income). Section 234 is the guard against exactly this manipulation. It empowers the tax department to throw a company out of the tonnage tax scheme if it abuses the scheme to obtain an undue tax advantage.

Who it applies to

• Only tonnage tax companies — that is, Indian shipping companies that have opted into and are operating under the tonnage tax scheme.
• It does not affect ordinary taxpayers, salaried individuals, or businesses outside shipping.
• It is invoked by the Assessing Officer (AO), but only with the prior approval of a senior officer (Principal Chief Commissioner or Chief Commissioner).

When does the scheme "not apply" — the abuse test

Under Section 234, the tonnage tax scheme shall not apply where a tonnage tax company is a party to any transaction or arrangement that amounts to an abuse of the scheme. A transaction/arrangement is treated as abusive if it produces a tax advantage for:

• a person other than the tonnage tax company (for example, a related/group company), or
• the tonnage tax company itself in respect of its non-tonnage (ordinary) activities.

What counts as a "tax advantage"

The section explains tax advantage broadly. It covers, in particular:

• Wrong allocation of expenses/interest/costs: where the allowance for any expense or interest, or any cost or expense allocated or apportioned, has the effect of reducing income or increasing the loss from the company's non-tonnage (ordinary) activities; and
• Loading of profits into the tonnage bucket: where a transaction or arrangement produces more than the ordinary profits that might be expected to arise from the tonnage tax activities.

In plain words: you cannot dump costs into your normal business to cut ordinary tax, nor artificially inflate profits inside the near-tax-free tonnage business.

The safeguards — you get a fair hearing

• Written order: The AO must exclude the company by a written order.
• Show-cause opportunity: The AO must first give the company a reasonable opportunity to explain why it should not be excluded (a show-cause notice).
• Senior approval: The order cannot be passed without the prior approval of the Principal Chief Commissioner or Chief Commissioner.

The bona fide defence

Section 234 will not apply — i.e., the company will not be excluded — if the company satisfies the AO that the transaction or arrangement was a genuine (bona fide) commercial transaction and was not entered into for the purpose of obtaining a tax advantage. This protects normal, honest commercial dealings.

Consequence — from when does exclusion bite

Where an exclusion order is passed, the company's option for the tonnage tax scheme ceases to be in force from the first day of the tax year in which the abusive transaction or arrangement was entered into. From that year, the company is taxed under the normal provisions of the Act on its actual profits — a materially higher tax bill.

How it interacts with related sections

• It complements the general conditions for the scheme in Section 232 and the other exit/withdrawal provisions in Section 233.
• It is the 2025 Act's re-enactment of the old Section 115VZC (with 115VZB) of the Income-tax Act, 1961 — the language and effect are substantially the same.

Practical implications

• Shipping groups must keep clean, arm's-length allocation of common costs between tonnage and non-tonnage activities.
• Related-party and intra-group transactions should be documented as commercially justified, not tax-driven.
• An exclusion is serious and retrospective within that year, so compliance is far cheaper than defending an abuse allegation.
