CTM22270 | ACT collection: calculations
From HM Revenue & Customs · Company Taxation Manual
ICTA88/S246 (6) covers:
the ACT payable and the tax credit on dividends and other qualifying distributions paid in the five day period to 5 April in the financial year for which the ACT rate changes,
and
ICTA88/SCH13 accounting etc, where an accounting period straddles 5 April in that financial year.
If the rate of ACT for any financial year differs from the rate last fixed you should check that the following rules are properly applied.
The ACT payable on a distribution made in the 5 days to 5 April is calculated using the rate applying in the previous financial year.
Apply ICTA88/S238 (1) (definition of ‘franked payments’), ICTA88/S231 (1) (tax credit) and Schedule 13 (collection of ACT) to that distribution as if the rate had not changed.
You may find that a distribution has been made on or before 5 April in an accounting period which extends beyond 5 April in that year and another distribution is made or franked investment income is received in that accounting period after 5 April. If so:
the company’s liability for ACT,
the amount of ACT, and
the amount of any surplus franked investment income,
for that accounting period are determined under ICTA88/S241 and ICTA88/SCH13 as if the part of the accounting period ending with and the part of it beginning after 5 April were separate accounting periods.
