PIM1003 | Introduction: Property Income: Income Tax
From HM Revenue & Customs · Property Income Manual
Key Points on current rules
Current legislation for property businesses carried out by individuals or partnerships is within Part 3 ITTOIA2005
Income from property profits and losses are mostly computed using the cash basis (see PIM1090 onwards) from tax year 2017-18, subject to certain exceptions. Prior to this they were calculated using normal trading income principles.
The basis period for a property business carried out by an Income Tax customer is the tax year (6 April to 5 April) with only two exceptions (see PIM1010 for more details. NB The trade basis period rules cease to apply from 6 April 2024 following transitional arrangements in the tax year 2023-24) – see the Business Income Manual from page BIM81200.
Relief for finance costs (mortgage interest etc.) in respect of a dwelling related loan is restricted for tax year 2017-18 and onwards (see PIM2050 onwards)
