Tax year end date changes: Payroll implications

by

Samantha Johnson assesses the impact a change in the tax year end would have on payroll calculations, statutory payments and more.

The Office of Tax Simplification's (OTS) announcement to review the tax year end date has been welcomed by some and criticised by others. The existing tax year has been in place for centuries with legislation and guidance built to reflect the 5 April.

The proposal to change this date to either the 31 March or 31 December will inevitably come with some challenges for payroll professionals.

In 2002, Ireland successfully made the move from 5 April to 31 December, showing that it is possible. Central to any change is the planning – specifically, in the transitional tax year. If the planning is done well, and solutions avoid complexity, the UK could adapt to this change with relative ease.

Thresholds

Many payroll calculations are centred around the thresholds which are set to apply to tax years and tax periods. The transitional year would need to set out pro-rated entitlement to those standard annual thresholds, such as the personal allowance, employment allowance and apprentice levy allowance.

On an individual basis, allowances that can affect tax-free pay such as the marriage allowance and working from home allowance must be adjusted to ensure entitlement is fairly reflected for individuals who are claiming these adjustments.

National insurance is calculated on an annual basis for directors, meaning that this will also require consideration. Moreover, the transition year would include a shorter month; therefore, those monthly national insurance thresholds may need to be adjusted to reflect that reduced period. There would need to be clear guidance to calculate the appropriate earnings levels for national insurance in these circumstances.

Statutory payments

The new tax year is also linked to changes in statutory payments – including sick pay, maternity pay and paternity pay. These payments increase annually, and whilst the exact date at which they apply does vary depending on the type of payment, it would be expected that there would continue to be alignment between the increases and the new tax year.

A change to 31 March would not create a significant change to timings; however, a change to 31 December would certainly create a more substantial impact. Statutory increases not being aligned to the start of the tax year would not be a desirable consequence of this change.

Gender pay gap reporting

The snapshot date for gender pay gap reporting is currently 5 April in the private sector, the same date as the end of the existing tax year. A move to 31 March or 31 December would leave this date without any identifiable point of reference; therefore, any change to the existing tax year should consider the effect on this area too.

Payroll schedules and software implications

Existing payroll schedules in many teams are well established and have been tried and tested. In payroll bureaux, there is even more of an emphasis on payroll schedules, where multiple deadlines are in place to manage hundreds or possibly thousands of clients.

The deadline for the full payment summary would not need to be amended with a tax year end change. Payments for PAYE, however, would be liable to being brought forward if the tax month was to end in line with the calendar month. This change could create further implications for the employer payment summary deadline and ultimately, create significant changes in payroll schedules across the UK.

I’m certain that the preference from payroll will be to retain existing deadlines to prevent unpicking complex and well-established internal processes.

Payroll professionals work hand in hand with software providers to deliver their services, and any change must come with sufficient notice to software providers to develop, test and apply any changes within their products.

Wider implications

National insurance contributions are used to calculate entitlement to the state pension. The pro-rated transition year (particularly if the tax year is moved to 31 December) would mean that employees do not get an opportunity to contribute a full year. Government would need to take a clear stance on how, and if, this would reduce any state pension benefits and provide clear messaging to ensure that individuals can take action to address this if required.

The link between RTI and universal credit has been in place for a number of years now. Earnings data is used to calculate the amount of universal credit due to an individual. The transition year and pro-rated thresholds could alter the net amount an employee receives.

Universal credit uses net pay to calculate entitlement; therefore, the government must ensure individuals are protected from any adverse effects that the transition year may have on their net income and ultimately, benefit entitlement.

Although 2021 saw the Budget announcement arrive late in March, under normal circumstances, it would be expected in the autumn proceeding the new tax year. This gives payroll teams and payroll software providers the chance to prepare and to react to any upcoming changes. Whilst a tax year end change to 31 March would not warrant changes to the existing Budget schedule, a change to 31 December would mean that government would need to adjust their schedules quite significantly. This could mean that any transition year would see two Budget announcements within six to nine months of each other.

What’s next?

The OTS has set out a plan to review the tax year end. Any recommendation to move forward with this change should be comprehensive and ensure that clarity and transparency are at the centre of all communications, with a clear plan put in place for any transition year. This is not an impossible task, but the size of the impact will be greater if a move to 31 December is the preferred option. Overall, the success of this change will absolutely depend on good preparation – as the old saying goes, fail to prepare, prepare to fail.

Two initial responses/thoughts:

1. Whilst a good first trawl across payroll-related aspects that will be impacted, there are some really major omissions - for instance ... holiday entitlement & pay, pension contributions and benefits (for both DB and DC types), cashflow for employers if HMRC payment due dates are brought forward, re-programming and/or replacing T&A devices, re-negotiation of annual hours contracts and/or work schedules, arguments over application of overtime rates, annual cost of BiKs that aren't 'available' for a full year, and many more.

2. The phrase 'transition year' has come to be used (mostly by politicians) to sound like there's only one set of changes to overcome - from 'where we are' to 'the new future' (after transitioning).
The reality here is that Payroll would need to operate in substantially different ways for 3 years on the trot ... which means that payroll developers would have to build transitional software that is then discarded after less than a year (and replaced with the 3rd variant). That is a major ask and, unlike RTI or AE etc, will undoubtedly be charged for (at full price).

One final, radical, thought.
If the majority of examples (relating to a full allowance for a slightly shorter year) mentioned in the article were dropped from the spec for the transition year, then I suspect the 'lost tax' would be less than the 'costs saved' (by HMRC and by the population of employers). Of course this would only be true if the new year-end were to be 31st Mar!

There is another aspect to changing the tax year end: it will alter the end/start of each tax month and thereby potentially 'encourage' employers to revisit their monthly pay date and payroll processing schedules. Might we see these dates move forward by, say, five days?

What is wrong with 5 April?

I know its a big of a strange date, but don't we all know that 5 April is the end of the tax year!

Why waste more time and resources. There are bigger issues to address, like cancelling MTD for Income Tax. If they need cash flow, then making 4 quarterly payments!

Agree both points
An established quirk understood by all who get involved

MTD ITSA unworkable
That would mean charging at least double for all the little easy jobs, and finding probably 2 new members of staff
Clients will accuse accountants of profiteering, despite my costs of staff, training and IT being higher than the extra fees

How will autofeed work for a non business bank account and a client that just does not do IT
