The Office of Tax Simplification (OTS) has issued a policy paper ‘Potential for moving the end of the tax year - Scoping document’. It offers two options to replace 5 April as the end of the tax year, 31 March or 31 December. 

The UK’s tax year for individuals has run from the 6 April to the 5 April since 1800, following the introduction of the Gregorian calender to Britain in 1752. Most other countries use either the calendar year or run their tax year to 31 March, whilst the most popular Company accounting period end dates are also 31 March and 31 December.

The OTS is undertaking a high-level review of the issues, costs and benefits of a change to the tax year end date for individuals, to include the wider implications for other areas such as tax credits and benefits.

The options as envisaged by the OTS are:

31 March:

31 December:

In carrying out its review, the OTS will consider:

Following their review the OTS plans to publish a report over the Summer of 2021. The policy paper does not give any indication of when any change might take effect.

Why does 5 April tax year end matter?

Anita Monteith of the Institute of Chartered Accountants in England and Wales (ICAEW), writing on Accountingweb looks at the impact of the 5 April year-end on for Making Tax Digital (MTD) for Income Tax Self-Assessment, she says:

"...Mandation of MTD ITSA is near and will require reporting based on the digital record of when transactions take place. It would help to be able to align the quarterly reporting obligations for VAT with those for income tax.

It would also help to align them with the other different sources of income to be reported for income tax. Otherwise, we could see an individual having multiples of the headlined ‘four’ quarterly reports to make each year.

For example:

Anita concludes that:

"The consequences of this [having a 5 April tax year-end] are that a VAT registered sole trader with a buy to let property would be making MTD reports on at least eight occasions in each year."
