Detailed guide: Register your client’s estate

When to register

If your client has an estate with a tax liability, you should register their estate by 5 October of the tax year after they died.

What you need

Estates

You need the:

  • name of the estate
  • estate address and telephone number
  • date the administration period ended

Details about the person that’s died

You need their:

  • name and address
  • date of birth and date of death
  • National Insurance number if still available

Personal representative

You need their:

  • name
  • email address and telephone number
  • National Insurance number and date of birth

You can save your progress, however you can’t update your registration once you submit it.

How to register

You need to have an agents service account. If you’ve already got one, you need the User ID and password you created when you set up the account.

If you don’t have an account you can create one the first time you register a estate. You’ll need your agency’s Unique Taxpayer Reference (UTR) and postcode to do this.

You can save your progress, however you can’t update your registration once you submit it.

What happens next

We will send your client a UTR – you’ll need it to send a tax return using the Self Assessment for Agents online service.
