To ask the Chancellor of the Exchequer, what his most recent estimate is of the tax revenues lost through residential landlords failing to declare their rental income.

The information requested is not available as HM Revenue and Customs (HMRC) does not make a separate estimate of the proportion of the total tax gap attributable to residential landlords.

However, HMRC does estimate the tax gap arising from individuals in employment who have not declared and therefore not paid tax on lettings income. The latest estimate of this tax gap was £540 million for the tax year 2018-19.
