What is Form IR6129?
Form IR6129, 'Notification of Letting of Properties', is how an owner tells Hong Kong's Inland Revenue Department (IRD) in writing that a property has been let out and that they are chargeable to Property Tax. Section 51(2) of the Inland Revenue Ordinance requires a person chargeable to tax for a year of assessment to inform the Commissioner in writing not later than 4 months after the end of the basis period, unless they have already been required to furnish a return. The IRD's notification page gives the deadline for Property Tax as 31 July.
It is a short bilingual form: your name and Hong Kong Identity Card or passport number, whether you are the sole owner, a co-owner or a joint owner, where the property is and its rating assessment number, the date it was let out and the monthly rent, and the postal address for the tax return. Use one form for each property.
FileIt walks you through it and prints your answers into the IRD's own PDF (the 7/2022 edition). It strikes out the title, identity document and type of ownership that don't apply, checks your HKID check digit, and files the finished PDF in your vault. You then sign it and send it to the IRD yourself — FileIt never files anything with the IRD.

How to fill out Form IR6129, step by step
1 Your name and identity
Give your full name surname first — FileIt prints it in capitals as SURNAME, GIVEN NAMES. The form prints 'Mr / Mrs / Ms / Miss' and 'Hong Kong Identity Card No. / Passport No.' and asks you to delete whichever is inapplicable; FileIt strikes those through on the English line. Give your HKID number with its check digit (FileIt checks it), or your passport number if you have no Hong Kong Identity Card.
2 Type of ownership and the property
Say whether you are the sole owner, a co-owner or a joint owner — FileIt strikes out the other two. Then give the full address of the property and its rating assessment number, which appears on the demand for rates for the property.
3 Letting date and rent
The date the property was let out, as DD/MM/YYYY, and the monthly rent in Hong Kong dollars.
4 Postal address
The address where the IRD should send the tax return you will need to complete.
5 Signature, telephone and date
Sign with the same signature you use on tax returns and past correspondence with the IRD, and give a day-time contact telephone number and the date.
Common mistakes to avoid
- Missing the deadline — the notice is due within 4 months after the end of the basis period, by 31 July.
- Putting two properties on one form — use a separate form for each property.
- Leaving 'sole owner / co-owner / joint owner' unstruck — delete the ones that don't apply.
- Writing the name given-name first instead of surname first.
- Giving the rent in a foreign currency, or an annual figure where the form asks for the monthly rent.
After you fill it out
Sign the form and send it to the Inland Revenue Department at the address printed on it, or by fax to 3170 5647, the number printed on the form.
The IRD then issues you a tax return covering the property, which you complete and file by its own due date.
FileIt keeps the completed PDF in your vault with your other property records, so you have a record of when you notified the IRD.
