The lower rate used where it applies

8.25% on the first HK$2 million of assessable profits and 16.5% on the rest. Only one company in a connected group can use the lower tier, and we check which.

PROFITS TAX IN HONG KONG

What Hong Kong profits tax asks of you, and what we do about it

1The rates

For a corporation, 8.25% on the first HK$2 million of assessable profits and 16.5% on the rest. Only one company in a connected group can use the lower tier. We apply the rates in your computation.

2Only Hong Kong profits

Hong Kong taxes only profits sourced in Hong Kong. A company can claim some or all of its profits are offshore, but the claim needs evidence and is often examined. On Premium we prepare and support it.

3When the first return is due

The Inland Revenue Department normally issues a new company's first return about 18 months after incorporation, with three months to file. Later returns are issued each April. We track the dates and remind you early.

4Filed with audited accounts

An active company files the return with audited financial statements. We run the audit and the return together. A dormant company is quoted separately.

5The employer's return

If the company has staff, the employer's return (BIR56A with an IR56B per employee) is issued each April and due within a month. Every OCTIS accounting and bookkeeping plan includes it.

6Keep your records

The Inland Revenue Ordinance requires business records to be kept for at least seven years. We tell you what to keep.

FAQ

Are profits earned outside Hong Kong taxed?

When do I file my first profits tax return?

The Inland Revenue Department normally issues a new company's first return about 18 months after incorporation, with three months to file. Later returns are issued each April.

Can I buy tax filing without the audit?

Not for an active company: the return is filed with audited financial statements. A dormant company is quoted separately.

What about the employer's return?

If the company has staff, the employer's return (BIR56A with an IR56B per employee) is issued each April and due within a month. It is included in every accounting and bookkeeping plan.
