Self Assessment – Register as a landlord
If you are not already registered for Self Assessment, you will need to register with HMRC as soon as you can after you start to let the property commercially.
You need to register by 5th October after the end of the relevant tax year. You could be fined if you don’t.
If you haven’t sent a return before
Register online and you’ll:
- get a letter with your 10-digit Unique Taxpayer Reference (UTR)
- be enrolled for the Self Assessment online service at the same time
You’ll also get a letter within 10 working days (21 days if you’re abroad) with an activation code.
