Changes from 1 April 2016
Finance Act 2016 extends the ability for profit averaging to five years and removes the marginal relief. Section 222A Circumstances in which claim for five-year averaging may be made in the Act states:
1. An averaging claim may be made under this section in relation to five consecutive tax years in which a taxpayer is or has been carrying on the qualifying trade, profession or vocation if the volatility condition in subsection (2) is met.
2. The volatility condition is that:
(a) one of the following is less than 75% of the other:
(i) the average of the relevant profits of the first four tax years to which the claim relates
(ii) the relevant profits of the last of the tax years to which the claim relates or
(b) the relevant profits of one or more (but not all) of the five tax years to which the claim relates are nil.
It is also important to note that:
3. Any of the first four tax years to which an averaging claim under this section relates may be a tax year in relation to which an averaging claim under this section or section 222 has already been made.
4. An averaging claim (‘the subsequent claim’) may not be made under this section if an averaging claim in respect of the trade, profession or vocation has already been made under this section or section 222 in relation to a tax year which is later than the last of the tax years to which the subsequent claim relates.
5. An averaging claim may not be made under this section in relation to the tax year in which the taxpayer starts, or permanently ceases, to carry on the trade, profession or vocation.
6. An averaging claim under this section must be made on or before the first anniversary of the normal self-assessment filing date for the last of the tax years to which the claim relates.
7. Where the claimant makes a valid averaging claim, the amount of the adjusted profits of each of the tax years to which the claim relates is the average of the relevant profits of those years (ITTOIA 2005, s223).
