01 New Companies: The First 18 Months After Incorporation Are the First Hurdle

After a Hong Kong company is incorporated, the Inland Revenue Department willAround the 18th monthSubmit the first capital gains tax return (BIR51/BIR52).

After receiving the tax return,Within 3 monthsThe bookkeeping and audit must be completed, and tax returns must be filed.

Hands-on advice: Don’t wait until you receive your tax return to start bookkeeping. You should begin organizing your books in the 12th month after the company is established; otherwise, if you wait until close to the deadline, the auditor’s schedule will be very tight, and the fees will be higher.

02 Existing Companies: Submit annual reports within one month after the anniversary date each year; tax returns are based on the tax assessment year.

The filing of Hong Kong profits tax is based onTax Year(April 1 through March 31 of the following year).

Every year, around April, the tax authority sends companies profit tax return forms to report their profits for the previous fiscal year.

Common fiscal year-end dates and tax filing deadlines:

⚠️ The tax filing deadline is subject to minor adjustments each year; the deadline listed on the tax return form actually mailed by the tax authority shall prevail.

03 Tiered Late Payment Fines: The Longer You Wait, the More It Costs

The worst-case scenario: Without bookkeeping and an audit, the tax authorities cannot verify your actual profits and will “estimate” a higher profit amount for tax purposes. You are responsible for proving that this estimate is incorrect—but without financial records, you have no evidence to support your case.

📌 If you have already received a notice of delinquency or a tax assessment notice, we recommend taking immediate action.
