Will the landlord register share data with HMRC?
Updated . Checked against official sources.
The government hasn't said. Nothing published so far confirms or rules out HMRC access. What is confirmed is that councils will use the register for enforcement, and that data will be handled under data protection law.
What we know
- The register records each property's rent amount and how often it's paid, alongside your identity and address.
- Councils will use it to target enforcement against landlords who don't comply.
- The government says it will safeguard landlords' privacy and follow data protection law, with details still to come.
- The exact information collected is set by secondary legislation.
What we don't know
- Whether HMRC, or any body other than councils, will have access
- On what legal basis any sharing would happen
If you have rental income you haven't declared
Whatever happens with the register, HMRC already runs the Let Property Campaign for landlords who want to tell it about undeclared rental income. Coming forward voluntarily usually leads to better terms than being found. Read HMRC's guide to making a disclosure, and consider speaking to an accountant.
