Guide to Online Stamp Duty Payment in HK

Landlady Mrs. Chan just signed a new tenant with a monthly rent of HK$18,000 for a two-year lease. The agent reminded: "Stamp duty must be paid within 14 days, otherwise there will be a fine." Mrs. Chan didn't want to queue up at the Inland Revenue Department again, so she decided to use the IRD e‑Stamp service. Below is a comprehensive guide on the online tax filing process, fees, penalties, and common pitfalls.

1｜Why is "stamping" necessary?

• The Stamp Duty Ordinance stipulates that the lease must be stamped and the stamp duty paid within 30 days from the date of signing
• An unstamped lease, although contractually valid, cannot be used to file a lawsuit for rent arrears; late stamping will result in a fine

2｜2025 Latest Stamp Duty Fees

• Monthly rent ≤ HK$25,000, lease term 1‑3 years → Tax rate 0.5% × total rent
• Mrs. Chan's case: $18,000 × 24 = $432,000 → Tax amount $2,160
• System calculates instantly, online payment available via FPS / Faster Payment System

3｜e‑Stamp Five Steps to Complete

• Log in to "e-TAX" > Select Electronic Stamp Duty Service
• Submit Application – Lease Agreement
• Enter details: Address, Lease Term, Monthly Rent, Deposit, Brokerage Fee (if any)
• System displays the tax amount → Pay via FPS or Bank Transfer
• Download the PDF "Stamped" copy of the lease agreement → Email to tenant and agent for record

4｜Penalty for Late Stamp Duty Payment

• ≤ 1 month: Tax amount × 2
• > 1 month but ≤ 2 months: Tax amount × 4
• > 2 months: Tax amount × 10 or HK$5,000 (whichever is higher)
• In 2024, there have already been cases where late payment resulted in a 10-fold penalty, leading to more losses than gains

5｜What to do in case of rent increase and renewal?

• After signing the renewal memorandum, similarly within 30 days, use the electronic stamping service to pay the tax; the tax amount is calculated based on "additional rent difference × remaining lease term × 0.5%"

Stamp duty cannot be delayed, with a maximum penalty of 10 times for late payment. Completing the online stamping ensures that the lease can be enforced in court for rent collection, and it also legally allows for the deduction of commissions and maintenance fees for tax purposes, killing multiple birds with one stone.
