ADJUSTMENTS FOR PRIVATE USE
HMRC will be running a digital campaign aimed at encouraging accurate private use adjustments of business expenses that are reported via Self Assessment returns. ** **
To be allowable for tax, expenses must be 'wholly and exclusively' incurred for the purposes of the business, with any appropriate adjustments being made for private use. Expense claims should therefore be restricted to those that relate to business use only, with partial claims for mixed private and business expenditure being apportioned based on the circumstances of the particular tax year.
Following a trial in 2024 involving 600,000 self-assessed individuals who were encouraged to make accurate private use adjustments, HMRC reported widespread inaccurate reporting of disallowable private use. HMRC now intend to open more enquiries into private use adjustments for business expense claims.
