Intra-Group Stamp Duty Relief: The 90% Threshold, the Application, and the Two-Year Restriction

At a glance

The easiest misunderstanding: relief is not “approved and safe forever”. If the transferee ceases to be associated with the transferor within two years, the relief can be clawed back — a sale timetable has to be considered alongside the restructuring timetable.

How is the 90% threshold actually counted?

You count beneficial ownership of the issued share capital, both sides have to be bodies corporate, and you have to count all the way through.

Where an individual sits in the middle of the structure, the practical fix is to interpose a holding company owning not less than 90% of each of X and Y. But interposing that layer itself (the step of transferring the X and Y shares into the holding company) generally does not attract relief — at the moment it is done, the association does not yet exist.

Two other places things go wrong: dilution through the layers (the holding company owns 90% of X, X owns 90% of Z, so the holding company’s effective interest in Z is only 81%); and the word “beneficially” (the registered holder is not necessarily the beneficial owner — where there is a nominee arrangement or a trust, substance governs). Draw a shareholding chart and work through it layer by layer before you start.

How is the relief applied for, and what has to be filed?

Meeting the conditions does not make it automatic — an application has to be made to the Stamp Office in respect of the relevant instrument, with the procedure set out in “Stamping Procedures and Explanatory Notes — Intra Group Relief” (IRSD124). For a property transfer, Form IRSD121 has to be completed and filed as one original plus two copies.

The supporting documents should be aimed at making the association plainly visible to the Stamp Office: a shareholding structure chart, each company’s documents and evidence of shareholding, the instrument of transfer, and the financial material supporting the valuation. Applications are reviewed case by case, the Stamp Office will ask questions about the structure, and the timetable should allow room for that. On the document list for an ordinary transfer, see share transfers and stamp duty.

Once relief is obtained, what cannot be done for two years?

The association cannot be broken up. If the transferee ceases to be associated with the transferor or a third party within two years of the transaction, restrictions apply — and the duty originally relieved may have to be paid.

The scenario that bites hardest is a sale: this year you use the relief to move shares into a new company and tidy up the structure; next year a buyer acquires that company, the shareholding drops below the threshold on completion, and the two-year period has not expired. So before restructuring, ask: is there any prospect of a sale, or of an investor coming in and diluting the holding, in the next two years?

I hear the threshold is being cut to 75% — should I wait?

The proposal exists, but it is not law. The 2026-27 Budget proposes relaxing the section 45 criteria: broadening the range of eligible business entities, and lowering the minimum threshold for association from 90% to 75%.

But a Budget proposal only takes effect once an amendment ordinance is passed, and until then the current 90% threshold governs. The Government has also indicated that, before the amendment ordinance comes into operation, transfers meeting the conditions of the new mechanism can submit an application for a ruling, with the Stamp Office deciding whether to grant relief after the law takes effect — so there is no need to pay first and claim a refund later.

So if the structure already clears 90%, proceed under the current mechanism. If it sits between 75% and 90%, a ruling application is worth considering — but you have to accept that the outcome waits on the legislation. This kind of judgement involves substantial sums; a tax adviser should be engaged.

Where do applications most often get stuck?

Four places. The shareholding falls below the threshold — multiplying through the layers takes it under 90%, or there is a minority shareholder in the chain. The parties do not qualify — an individual sits in the middle, or one side is an entity the section does not cover. The two-year period — a sale or fundraising too soon after the restructuring. The documents do not hold up — the shareholding chart and the financial material do not reconcile.

The first three are structural problems to be solved before the instrument is signed; only the last is a documentation exercise. Separately, a restructuring changes the shareholdings, so the significant controllers register has to be reviewed afterwards; and where new shares or a capital reduction are involved, read it with the capital increase and reduction procedures.

Want to know whether this route works before you start?

The most expensive mistake with intra-group relief is doing it in the wrong order — the instrument signed, the deadline closing in, and only then discovering the structure does not clear the threshold.

This is general information. The conditions, application procedure and forms are as most recently published by the Stamp Office of the Inland Revenue Department (ird.gov.hk); the 75% threshold and the broadened range of entities mentioned here are Budget proposals, and the amendment ordinance as finally passed governs. This does not constitute legal or tax advice; for individual situations, consult a professional.
