Register an offshore property developer for Corporation Tax

Find out how to register for Corporation Tax if you are a non-UK resident company dealing in or developing UK land or property.

Who should register

A non-UK resident company dealing in or developing UK land should register for UK Corporation Tax.

Dealing in or developing UK land is where property or land is acquired or developed with the aim to profit from disposal. This is different from where property is acquired to hold as an investment, such as rental income.

Register if any of the following apply:

  • you carry on a trade of dealing in or developing UK land

  • you hold the UK land as trading stock

  • a main purpose of acquiring or developing the UK land was to realise a profit from disposing of the land

The rules for offshore property developers are complex. You may wish to ask for advice from a professional adviser about your tax position.

When to register

You become liable to UK Corporation Tax on the date a disposal of UK land is made.

You must register within 3 months of the date of disposal.

What you’ll need

To register an offshore property developer for Corporation Tax, you’ll need the following information:

  • your company name

  • country of incorporation and your foreign registration number, if you have one 

  • any previous names your company has had 

  • address of the company’s registered office 

  • address of the company’s principal place of business in the UK (if different from the registered office) 

  • date of incorporation 

  • date the company became liable to Corporation Tax

  • date the company intends to prepare its first accounts

  • name of the parent company and its registered office address — if the company is part of a group

  • your first and last names 

  • your working relationship to the company or role in the company 

  • your telephone number and email address

Other ways to register

If you’re unable to register online, you can write a letter to HMRC instead.

You’ll need to create a 10-digit dummy Unique Taxpayer Reference (UTR) and should include this at the top of your letter.

To create a dummy UTR, use the year and month of the date you are sending your letter followed by six 5s — YYMM555555. For example, if you are sending your letter in July 2024, the dummy UTR would be 2407555555.

You will also need to include all the information from the ‘What you’ll need’ section in your letter.

Send your letter to:

Corporation Tax Services
HM Revenue and Customs
BX9 1AX
United Kingdom

After you’ve registered

The dummy UTR should only be used to chase the progress of your registration.

HMRC will process your registration and send your Corporation Tax UTR by post.

You will need to send HMRC a 64-8 form if you have appointed a tax agent in the UK.
