HM Revenue & Customs (HMRC) recovered £104.3 million in unpaid tax from landlords during the 2025/26 financial year. This figure represents the third year in a row that the amount recovered has surpassed £100 million.
During the same period, landlords submitted 11,511 voluntary disclosures, the highest number recorded since 2018/19. The average payment made through these disclosures was £9,063, a decrease from £13,713 in the previous year.
These figures, obtained by accountancy firm Price Bailey, include tax recovered through the Let Property Campaign, as well as compliance actions against non-responders and discovery assessments. Andrew Park, a tax investigations partner at Price Bailey, noted that most voluntary disclosures are now initiated by HMRC 'nudge letters', indicating a trend towards a larger number of smaller cases.
HMRC is reportedly using Land Registry data to identify individuals owning multiple residential properties who may have undeclared rental income. Mr Park also highlighted that changes to mortgage interest tax relief and the distinction between revenue expenses and capital improvements continue to cause issues for landlords, leading to what he described as 'phantom profit' effects and compliance failures.
