Introduction: Mark Your Calendar to Avoid Penalties

Missing a Hong Kong tax deadline can result in penalties, surcharges, and unnecessary interest charges — even if your payment eventually arrives. The IRD (Inland Revenue Department) publishes a strict filing and payment schedule each year. For 2026-27, understanding the key dates — BIR60 issuance, filing deadlines, payment deadlines, provisional tax, business registration renewal, and Mandatory Provident Fund (MPF) contributions — is critical to staying tax-compliant.

This guide provides a complete 2026-27 Hong Kong tax calendar in table format, with explanations for each deadline category.

2026-27 Hong Kong Tax Calendar Table

Key Deadlines Explained

BIR60 Filing Timeline (May-August 2026)

The BIR60 is the Individual Tax Return form issued by the IRD for sole proprietors and self-employed individuals. The process follows this timeline:

• May 2026: IRD mails BIR60 forms to all qualifying taxpayers

• June-July 2026: Standard 1-month paper filing deadline from the issue date printed on your form

• July-August 2026: If filing via e-Tax, you automatically get a 1-month extension, typically pushing deadline to late July or early August

Pro Tip: File electronically via eTAX portal to access the extension automatically and reduce manual errors. The portal is accessible 24/7 with your eTAX username/password.

Business Registration Renewal (Annual, On Your Anniversary Date)

Every business registration must be renewed annually on its anniversary date (the date it was first registered). Failure to renew results in an automatic penalty of up to HK$5,000. The renewal cost is HK$2,200.

Action Item: Mark your business registration anniversary date in your calendar now. Most businesses renew in the same month each year (e.g., if you registered in March 2023, your next renewal is March 2026).

Provisional Tax (January & August 2026)

If the IRD believes your current-year profit will be high, it may issue a Provisional Tax Assessment in January and August. You must pay within 1 month of the issue date. This applies mainly to established businesses with declared profits above HK$2 million.

Example: If you receive a provisional tax notice on August 15, 2026, payment is due by September 15, 2026.

MPF (Mandatory Provident Fund) Monthly Contribution Deadline (By 10th of Following Month)

If you have employees, you must contribute 5% of their salary to their MPF account (capped at HK$1,500/month). Both your employee contribution (5%) and employer contribution (5%) are due by the 10th of the month following the contribution month.

Example Timeline for March 2026 contributions:

• Contribution month: March 2026

• Due date: April 10, 2026 (by 10th of following month)

• Penalty if late: Up to HK$5,000 + surcharge of 5-10%

Salaries Tax Filing (Form IR56E or IR56F Due by March 31, 2027)

If you employ staff, you must file a year-end Salaries Tax reconciliation report (either Form IR56E for individuals or IR56F for corporations) by March 31, 2027. This summarizes all salaries paid, deductions made, and Salaries Tax remitted during the tax year.

Profits Tax Assessment Payment (1 Month from Notice)

After you file your BIR60, the IRD assesses your income and issues a Profits Tax Assessment Notice. You have 1 month from the issue date to pay. If you cannot pay in full, contact the IRD immediately to request an installment plan.

Late Filing and Payment Penalties

Late Filing Penalty:

• Filing 1-3 months late: Warning + admin fee (varies)

• Filing 3-6 months late: HK$600 + 5% of assessed tax

• Filing >6 months late: HK$1,200 + 5% of assessed tax

Late Payment Interest:

• Interest accrues at 8% per annum from the due date

• Compounded monthly

• Example: If you owe HK$10,000 and are 3 months late, you owe approximately HK$10,200 in interest alone

Recommendation: Always file and pay on time. If circumstances prevent you from meeting the deadline, file what you can and contact the IRD proactively to explain and negotiate a late-filing arrangement. The IRD is more lenient with filers who come forward voluntarily than with those who ignore deadlines.

2026-27 Tax Year Key Changes

Based on the 2026-27 Hong Kong Budget announcements, key changes for the coming tax year include:

• Personal Allowance: HK$145,000 proposed (verify current amount)
