Register your client’s estate

Register your client’s estate online if you’re a tax agent or adviser.

Who should register

You only need to register your client’s estate if any of the following apply, the:

  • value of the estate exceeds £2.5 million
  • value of assets sold by the personal representative in any one tax year exceeds £500,000
  • total tax due exceeds £10,000

Who should not register

You do not need to register if the estate’s only income is from savings, as long as the tax due is less than £100 in any one tax year.

If the tax due is from income other than savings, or exceeds £100 tax due in any one tax year, you should use the informal payment arrangements.

When to register

Register the estate with HMRC to obtain a Unique Taxpayer Reference (UTR) by 5 October after the tax year when the estate starts to receive income or has chargeable gains on which tax is payable.
