Form BIRS1 Election for Two-Tiered Profits Tax Rates

Form BIRS1 Election for Two-Tiered Profits Tax Rates

Corporations opt into Hong Kong’s two-tiered profits tax regime by submitting Form BIRS1 with their Profits Tax Return (BIR51) for the relevant year of assessment. The two-tiered system offers a clear tax saving: the first HK$2 million of assessable profits are taxed at a reduced rate, with any excess taxed at the standard rate.

Eligibility and Benefit of the Two-Tiered Rates

The two-tiered profits tax rates regime provides relief for smaller businesses. Corporations pay 8.25% on the first HK$2 million of assessable profits, half the standard 16.5% rate. Profits above HK$2 million are taxed at 16.5%. This concession is limited to one entity per group of associated entities for any given year of assessment.

To qualify, a corporation must be chargeable to profits tax under the Inland Revenue Ordinance (Cap. 112). The election is made annually. The benefit is direct: a corporation with HK$2 million in assessable profits saves HK$165,000 compared to the standard rate (HK$330,000 at 16.5% versus HK$165,000 at 8.25%).

BIRS1 Two-Tiered Tax Election Hong Kong

The BIRS1 two-tiered tax election Hong Kong is a specified IRD supplementary form. It is not a standalone return; it must accompany the main Profits Tax Return (BIR51). The form serves as the corporation’s formal declaration to be taxed under the two-tiered regime for that assessment year.

The IRD provides Form BIRS1 on its official forms index as a downloadable PDF, which can be completed manually or electronically. Corporations filing through the Business Tax Portal can make the election digitally as part of the return submission process.

Elect Two-Tiered Profits Tax Form

To elect two-tiered profits tax form BIRS1, the corporation must complete these fields:

• Part A - Corporation Details: Enter the corporation's name, Business Registration Number, and the year of assessment.
• Part B - Election Declaration: Tick the box to confirm the election. The declaration states the corporation is not a member of a group of associated entities, or if it is, that no other entity in the group has made the election for the same year.
• Part C - Associated Entities (if applicable): If part of a group, list the name and Business Registration Number of each associated entity. The IRD uses this to verify only one entity claims the reduced rate.
• Part D - Signature and Date: The form must be signed by a director, company secretary, or authorised representative. The signing date must be on or before the Profits Tax Return’s due date.

Attach the completed form to the BIR51. Paper filers include BIRS1 as a supporting document. Electronic filers make the election through the Business Tax Portal interface, which generates a digital version of the form.

Inland Revenue BIRS1 Guide

The Inland Revenue BIRS1 guide assists taxpayers in completing the form correctly. It details eligibility criteria, the definition of associated entities, and the consequences of an incorrect election.

The election is irrevocable for the year of assessment. A corporation cannot later revert to the standard rate. If a corporation incorrectly claims the reduced rate, the IRD will assess profits at the standard rate and may impose penalties. The reduced rate applies only to assessable profits computed under the Inland Revenue Ordinance. It does not affect provisional tax or the rate on non-assessable profits.

Tax representatives should consult the IRD guide before completing the election.

Profits Tax Rate Election Form

The profits tax rate election form BIRS1 must be submitted with the Profits Tax Return (BIR51) for the relevant year of assessment. The BIR51 is the main corporate tax return and includes a section for declaring assessable profits. The BIRS1 confirms the election for the two-tiered rates.

The filing deadline depends on the corporation's accounting date. For most corporations with a 31 December year-end, the return is due by 15 August of the following year. For a 31 March year-end, the deadline is 15 November. The IRD specifies the filing deadline in its return issuance letter.

Corporations filing electronically must make the election within the portal before submission. The portal generates a confirmation. Paper filers must include the signed BIRS1 with their return.

Irrevocability of the Election

Once submitted for a year of assessment, the election is irrevocable. The IRD will apply the two-tiered rates for that year, and the corporation cannot withdraw or amend the election. If a corporation later discovers it was not entitled to the reduced rate, it must notify the IRD and may face additional tax and penalties.

Irrevocability applies per year of assessment. A corporation can choose not to elect for a subsequent year, but the decision for the election year is final. Confirm eligibility before submitting the form.

Completing and Submitting Form BIRS1

Follow these steps to complete and submit Form BIRS1:

1. Download the form: Obtain Form BIRS1 from the IRD forms index at https://www.ird.gov.hk/eng/paf/bus.htm.
2. Complete the fields: Fill in corporation details, the year of assessment, and the election declaration. List associated entities in Part C if applicable.
3. Sign the form: A director, company secretary, or authorised tax representative must sign. The signature confirms the information is true and correct.
4. Attach to BIR51: Include the completed BIRS1 with the Profits Tax Return. Paper filers should staple it to the return. Electronic filers follow portal instructions to attach the form.
5. Submit by the due date: Ensure the return and BIRS1 are submitted on or before the filing deadline. Late filing may result in penalties and interest.

A tax representative can submit the election on behalf of a corporation through the Tax Representative Portal, provided they have authorisation.

Tax Computation and the Election

The election directly affects the tax computation. The corporation or its tax representative must calculate assessable profits and apply the two-tiered rates: 8.25% on the first HK$2 million, and 16.5% on the remainder. The BIRS1 confirms entitlement to this treatment.

For a short period of assessment, the HK$2 million threshold is apportioned on a time basis. The IRD provides guidance on this calculation in the BIRS1 guide.

The tax computation is submitted with the BIR51, in iXBRL format for electronic filers or as a paper schedule. The BIRS1 is a separate supporting document.
