Two Tiered Profits Tax Rates Hong Kong Eligibility and Rules

Two-Tiered Profits Tax Rates Hong Kong: Eligibility and Rules

Hong Kong’s two-tiered profits tax rates cut the liability for smaller businesses. The first HK$2,000,000 of assessable profits is taxed at a lower rate. For corporations, that rate is 8.25%. The remainder is taxed at 16.5%. For unincorporated businesses, the rates are 7.5% and 15%. Only one entity in a group of connected entities may claim the concession. The election is made on the profits tax return.

Hong Kong Two-Tiered Tax Rates Eligibility

Any corporation or unincorporated business chargeable to profits tax may elect the lower rate. The condition is straightforward: no other entity in the same group can have already claimed the concession. The IRD applies the concession automatically when the taxpayer files its profits tax return and meets the conditions. There is no separate application form. Make the election by completing the relevant boxes on Form BIR51 (for corporations) or Form BIR52 (for persons other than corporations).

The concession applies per entity, not per group. Where a group of connected entities exists, only one entity benefits from the lower rate on the first HK$2,000,000 of its assessable profits. The other entities in the group are charged at the upper rate on all their profits. Including the first HK$2,000,000. That means 16.5% for corporations and 15% for unincorporated businesses.

Connected Entity Rule Hong Kong Profits Tax

The connected entity rule is the key restriction. Under the Inland Revenue Ordinance (Cap. 112), an entity is connected with another if one controls the other or if both are under common control. Control includes the ability to influence the financial or operating policies of the entity, whether through shareholding, voting rights, or other arrangements.

The rule applies to both corporations and unincorporated businesses. If a Hong Kong company owns 100% of a subsidiary, both are connected entities. Only one may elect the two-tiered rates. The same applies if two companies are under common ownership by the same individual or group. The IRD examines the relationship at the end of the basis period for the year of assessment. If the entities are connected at that time, the restriction applies.

Declare connected entities on the profits tax return. The IRD may request details of the group structure and the identity of the entity that has elected the concession. Failure to disclose connected entities can result in reassessment of the lower rate and the imposition of penalties.

Hong Kong Profits Tax Rate 8.25%

The 8.25% rate applies to the first HK$2,000,000 of assessable profits of a corporation. That is half the standard corporate rate of 16.5%. The concession is available for each year of assessment. A corporation can claim it annually as long as it remains eligible. The rate applies to the profits of the basis period for that year of assessment.

Take a corporation with assessable profits of HK$2,500,000 for the year of assessment 2025-26. The tax liability is calculated as: HK$2,000,000 at 8.25% (HK$165,000) plus HK$500,000 at 16.5% (HK$82,500), for a total of HK$247,500. Without the concession, the entire HK$2,500,000 would be taxed at 16.5%, giving HK$412,500. A saving of HK$165,000.

The concession does not apply to profits subject to the standard rate under specific provisions, such as certain types of income from intellectual property or royalties. The IRD provides guidance on the application of the two-tiered rates in its practice notes.

Two-Tiered Rates Unincorporated Business Hong Kong

Unincorporated businesses, sole proprietorships and partnerships, benefit from a similar two-tiered structure. The rate is 7.5% on the first HK$2,000,000 of assessable profits and 15% on the remainder. This mirrors the corporate structure but at lower rates, reflecting the different tax treatment of unincorporated entities.

The same connected entity rule applies. If an individual controls multiple unincorporated businesses, or if a partnership is connected to another entity, only one may elect the lower rate. The election is made on Form BIR52.

For partnerships, the concession applies at the partnership level, not at the partner level. Compute the partnership’s assessable profits and apply the two-tiered rates to the partnership as a whole. Each partner then reports their share of the partnership profits on their individual tax return. The lower rate has already been applied at the partnership level.

How to Elect on the Profits Tax Return

Make the election when filing the profits tax return. For corporations, that is Form BIR51. For unincorporated businesses, Form BIR52. The return includes a section where the taxpayer must indicate whether it has any connected entities. If the taxpayer has no connected entities, claim the concession by completing the relevant box.

If the taxpayer has connected entities, nominate one entity to receive the concession. The nomination is made on the return. Provide details of the connected entities and confirm that no other entity in the group has elected the concession for the same year of assessment. The IRD may request supporting documentation, such as a group structure chart or confirmation from the other entities.

The election is made for each year of assessment separately. A taxpayer that claimed the concession in one year may not automatically claim it in the next year if the connected entity rule applies differently. Review the group structure at the end of each basis period. Make a fresh election if necessary.

Provisional Tax and Holdover

The two-tiered rates also apply to provisional tax. When the IRD issues a notice of assessment for provisional profits tax, it applies the two-tiered rates to the estimated assessable profits for the current year of assessment. If the taxpayer’s actual profits are lower than the estimate, apply for a holdover of the provisional tax. The grounds for holdover include that the assessable profits for the year are less than the amount on which the provisional tax was based.

The holdover application must be made in writing to the IRD before the due date for payment of the provisional tax. The IRD will consider the application and may reduce the provisional tax payable. If the taxpayer’s actual profits are higher, the difference is collected when the final assessment is issued.

Block Extension and Filing Deadlines

The IRD publishes a block extension letter each year, setting later filing dates for profits tax returns where a tax representative is appointed. The block extension applies to returns for the year of assessment. The due date depends on the accounting date of the entity. Entities with an accounting date of 31 December may have a filing deadline of 15 August of the following year. Those with an accounting date of 31 March may have a deadline of 15 November.

The block extension does not affect the due date for payment of tax. Provisional tax must still be paid by the original due date, even if the return is filed later under the block extension. Check the IRD’s block extension letter for the specific deadlines applicable to your accounting date.
