Any self-employed business whose accounting year differs from the tax year (31 March is treated the same as 5 April), will have overlap profits e.g. accounting year end of 31 December. Overlap profits are profits taxed twice in the second and potentially third tax year under the current basis period rules. The figure should be entered on an individual’s tax return and carried forward each year until it is utilised.
Additional profits arising in the transitional period will be spread over a period of five years under an automatic election. It will be possible to elect out of the spreading to accelerate the charge. There will be a balance between the cash flow implications of paying all the tax in one go against the risk of higher tax rates (due to rate changes and/or higher profits) in the future. We can help with projections.
Self-employed individuals should remember that additional profits from the transitional period will be subject to the new Health and Social Care levy of 1.25% being introduced from 6 April 2022, meaning a marginal rate of 48.25% for additional rate taxpayers.
Taking an example of 31 December:
2023/24 tax year (the transitional year):
For businesses with higher profits in 2023/24 due to the change in basis, there is an automatic election to spread those additional profits over a period of five years, which you can opt out of.
2024/25 tax year (tax year basis):
• 6 April 2024 to 5 April 2025 (again, generally pro-rated from the two accounting periods)
• Pension contributions: in the transitional year, self-employed individuals should take care when calculating how much they can contribute to their pension. This is because their income may be inflated due to bringing profits forward into 2023/24 which are not covered by overlap relief. The annual allowance of £40,000 is restricted by £1 for every £2 above the income threshold of £240,000 until their income is above £312,000 when the annual allowance is £4,000 (gross). Any unused allowances from the prior three tax years can also be taken into consideration.
• Retiring partners: the timing of a self-employed individual retiring from the business is crucial from both a commercial and a tax perspective so that the tax relief on their overlap relief is optimal. Where partners are approaching retirement, the tax implications of the proposed date should be established and consider whether an alternative date is beneficial due to the introduction of the new rules.
• Capital in the business: the reform to basis periods provides the perfect opportunity for a business to review their level of capital. The business should consider whether their level of capital is sufficient given the new rules being introduced, partners retiring and paying them out and new partners joining, either lateral hires or internal promotions.
HMRC published draft legislation in Finance Bill 2021/22, which is currently before Parliament.
In the meantime, businesses should establish the cashflow impact of the changes to plan for the tax payment due on 31 January 2025 and beyond. Businesses may also want to consider the impact of changing their year-end to 31 March to simplify their tax affairs from 6 April 2024.
