TC09493 - [2025] UKFTT 00456 (TC)

There was no dispute between the parties as to the relevant legislation which we summarise below.

By section 681B Income Tax (Earnings and Pensions) Act 2003 (which was inserted by Finance Act 2012 with effect for child benefit payments made after 7 January 2013) a person is liable to a charge to income tax, the HICBC, for a tax year if:

His adjusted net income (“ANI”) for the year is greater than £50,000.

His partner’s (“partner” is defined in section 681G) ANI is less than his.

He or his partner are entitled to child benefit.

The assessments have been raised pursuant to HMRC’s discovery assessment powers as provided in section 29 TMA. Accordingly, HMRC bear the burden of establishing that they have discovered that an amount of income which ought to have been assessed to income tax has not been so assessed.

In the case of HMRC v Jason Wilkes [2020] UKUT 0150 (TCC) (“Wilkes”)the UT determined that HMRC had no power to make a discovery assessment in respect of the HICBC on the basis that the child benefit was not an amount of income which should have been assessed to income tax. The HICBC is a free-standing charge to tax.

Following the decision in Wilkes the provisions of section 97 Finance Act 2022 (“Section 97”)were enacted such that section 29 TMA was amended providing for a discovery assessment to be issued where “an amount of income tax … ought to have been assessed but has not been assessed” thereby providing for HICBC to be assessed by way of discovery assessment. Whilst the provision is generally only prospective Section 97 also provides that where a discovery assessment has been made to collect HICBC prior to tax year 2021/22 the provision is retrospective unless 1) pursuant to Section 97(5) a notice of appeal was given to HMRC in respect of the assessment prior to 30 June 2021 and the Wilkes basis of challenge was asserted in that appeal on a date prior to 30 June 2021; or 2) pursuant to Section 97(6) a notice of appeal was given to HMRC in respect of the assessment prior to 30 June 2021, the appeal was the subject of a temporary pause which occurred prior to 27 October 2021 and “it is reasonable to conclude that the temporary pausing of the appeal occurred (wholly or partly) on the basis that [the Wilkes issue] is, or might be, relevant to the determination of the appeal”. The appeals which are subject to the retrospective statutory amendment are defined as “protected appeals”. In this regard the protection offered is to HMRC and not the taxpayer.

Section 7 TMA provides that if a person is chargeable to income tax he must notify HMRC of that fact within 6 months after the end of the tax year. But if his income consists of PAYE income and he has no chargeable gains he is not required to notify his chargeability to income tax unless he is liable to the HICBC.

By virtue of section 34(1) TMA, HMRC may raise a HICBC discovery assessment at any time within 4 years of the end of the tax year to which it relates. They also have the power, in consequence of section 36(1A) TMA, to raise the assessment within a period of 20 years of the year of assessment where the loss of tax arises because of a failure to notify liability to a charge to tax under section 7 TMA. That section provides that if a person is chargeable to income tax, they must notify HMRC of that fact within 6 months after the end of the tax year. But if their income consists of PAYE income and they have no chargeable gains they are not required to notify their chargeability to income tax unless they are liable to the HICBC. In consequence of the provisions of section 118(2) TMA, the 20-year assessment provisions do not apply where the taxpayer establishes a reasonable excuse for the failure to notify their liability under section 7 TMA. However, HMRC will always have a period of 4 years in which to make a discovery assessment for a protected assessment.
