HMRC has begun writing to landlords where the information it holds from third parties does not appear to match the taxpayer's records. The letters encourage recipients to review whether all rental income has been declared and remind them of their obligations under Making Tax Digital (MTD) for Income Tax.
HMRC receives information from a variety of sources, including tenancy deposit schemes and other statutory reporting systems. This data is increasingly being used to identify landlords whose tax returns may not accurately reflect their property income.
If you receive one of these letters, it is important not to ignore it. HMRC asks landlords to review their position and take action by the deadline stated in the correspondence. Where there is undeclared rental income, HMRC expects the taxpayer to make a disclosure. If there is nothing to declare, HMRC should still be informed using the contact details provided.
The stakes can be significant. HMRC warns that if it later opens a compliance check or criminal investigation, any disclosure made at that stage may be treated as a "prompted" disclosure, potentially leading to higher penalties.
The letters also remind landlords to consider whether they have any capital gains tax obligations following the disposal of a rental property and whether they fall within MTD for Income Tax.
For landlords, the message is clear: ensure rental income is fully declared and maintain accurate records. If you receive such a letter, please notify us as soon as possible, as we can help.
