In the Budget, the government announced a new requirement for large businesses to notify HMRC whenever they take a tax position which HMRC is "likely" to challenge. This measure will take effect from April 2021 and the government has now issued a consultation on the notification process.
Through these new rules, HMRC are aiming to bring forward the time at which HMRC becomes aware of cases where large businesses have adopted a position with which they may disagree and so to accelerate the point at which discussions occur on uncertain tax treatment, and ultimately the point at which HMRC receives any tax agreed to be due. As far as possible, the rules will mirror the existing Senior Accounting Officer (SAO) regime, which businesses will already be familiar with. However, unlike the SAO regime, this measure will also apply to partnerships and LLPs.
In their consultation document, HMRC acknowledge that in some cases taxpayers may make a judgement on a particular tax position from a position of genuine uncertainty, whilst in others taxpayers may be deliberately pushing the boundaries of the law to their advantage. HMRC do not propose to differentiate between those situations, and, as a result, reporting may not come with the same stigma as reporting under other anti-avoidance provisions such as DOTAS.
The new rules will only apply to "large" businesses as they are defined under the SAO regime, i.e. those with either a turnover of more than £200 million or a balance sheet of more than £2 billion. A wide range of taxes will be covered, again mirroring the SAO regime, this would include corporation tax, income tax, VAT, SDLT and SDRT. Positions already disclosed under another regime, such as DOTAS or DAC 6, or which businesses are already discussing with HMRC under an ongoing enquiry, will be excluded.
The government have proposed that to determine when a tax position is "uncertain", the rules will draw on international accounting standards (namely IFRIC23), which require an assessment of whether it is "probable" that the proposed tax treatment will be accepted by the relevant tax authority (rather than whether it is very likely or certain). This will require a judgement call at the time when the notification is due and HMRC do not proposed to require taxpayers to revisit their decision unless the tax position is ongoing into a subsequent accounting period. HMRC may also list certain decisions made by taxpayers that should automatically be reported, such as the decision to apply a VAT rate other than the standard rate to new goods or services.
The consultation suggests that only uncertain tax treatments with a tax impact of at least £1m per year would be caught. This materiality threshold will seem low for many businesses, but HMRC have stated that they are unwilling to move to a balance sheet based test.
The notification process and penalties will also mirror the SAO regime. There will be a single annual notice to be made 6 or 9 months after the end of the accounting period. Penalties of £5,000 will apply for failure to notify HMRC, both to the relevant business and also to the nominated individual responsible for making the notification. The rules may drive large businesses to seek independent advice on a broader range of tax compliance matters, where decisions over which there is a degree of uncertainty are currently made in-house.
