INTM550070 | Hybrids: introduction: when does the legislation take effect

Part 6A of the Taxation (International and Other Provisions) Act 2010 was introduced by section 66/Schedule 10 of Finance Act 2016 (FA 16) and has effect from 1 January 2017.

The commencement provisions for chapters 3 to 11 are set out at paragraphs 18 to 22 of Schedule 10, FA 16.

Broadly speaking, the legislation applies from 1 January 2017 for

• deduction/non-inclusion mismatches arising from deductions on or after that date

• deduction/non-inclusion mismatches arising from deductions in a payment period beginning on or after that date

• double deduction mismatches for accounting periods beginning on or after that date

• imported mismatch payments arising from deductions on or after that date

• imported mismatch payments arising from deductions in a payment period beginning on or after that date

There are transitional rules for payment periods and accounting periods that begin before 1 January 2017 and end after that date at paragraphs 23 and 24 of Schedule 10, FA 16.

In these cases, the payment/accounting period is treated as 2 separate taxable periods

• one ending on 31 December 2016, and

• the other beginning on 1 January 2017

Amounts are apportioned to each of these periods on a time basis, unless that produces a result that is unjust or unreasonable. In those circumstances, the amounts should be apportioned on a just and reasonable basis.

For transactions between 16 March 2005 and 31 December 2016 involving hybrid mismatches the arbitrage rules set out at INTM590000 onwards may apply.
