BIM71085 - Computation of liability: overlap relief - how given


Overlap relief is given as a deduction in calculating the profits of the trade for:


  • the tax year in which there is a change of accounting date, if the basis period for that tax year is longer than 12 months, see BIM71090; and/or
  • the tax year in which the trade ceases, see BIM71095.

A deduction for overlap relief only reduces the assessable profit for the year in which the relief is given. There are no circumstances in which the figure of ‘net profit’ for a year (that is the profit after deduction of overlap relief) should be used in any apportionment to calculate the profits of an adjacent year.

Overlap relief is a mandatory deduction. The full amount of the relief available for a particular tax year must be given as a deduction for that tax year. No part of the deduction can be waived.

If giving overlap relief creates or enhances a loss, that loss is available for loss relief in the normal way.
