As a trusted provider of cloud accounting services, we at The Numbersmith understand the importance of staying informed about changes in tax regulations. One significant change that affects many of our clients is the new rules for reporting income from self-employment and partnerships, known as basis period reform. In this blog post, we'll dive into the details of these changes and how they might impact your business, providing you with the information and guidance you need to navigate this transition with confidence.

What are the Changes to Reporting Income from Self-Employment and Partnerships?
Basis period reform is a set of new rules that change how self-employed individuals and partnerships report their taxable profits on their self-assessment tax returns. Starting from the 2023/24 tax year, your taxable profit will be based on the income earned during the tax year itself (6 April to 5 April), regardless of your accounting period.
This means that unincorporated businesses will no longer be able to use their chosen accounting period end date when calculating their taxable income. Instead, they will need to apportion profits based on the tax year, which may require additional calculations and adjustments.

Why is This Change Happening?
The goal of basis period reform is to simplify the way businesses report their income and pay taxes. Under the old basis period rules, businesses could have different accounting periods, which could lead to confusion and complexity when calculating taxable profits.
This was particularly true for businesses with accounting year-ends that differed from the tax year, as they would need to apportion their profits and make adjustments to determine their tax liability.
By aligning the reporting of income with the tax year basis, the new rules aim to make the process more straightforward and reduce the administrative burden on businesses. It also brings the UK's tax system more in line with other countries, where taxable income is typically based on the tax year rather than individual accounting periods.

How Will This Affect My Business?
The impact of basis period reform on your business will depend on your current accounting year-end date. If your business's accounting period ends between 31 March and 5 April (inclusive), you likely won't see much change, as your accounting year is already aligned with the tax year.
However, if your accounting period ends on a different date, you'll need to make some adjustments when reporting your income. This is because you'll now need to calculate your taxable profit based on the income earned during the particular tax year rather than your accounting period.
For example, let's say your business's accounting year ends on 31 December. Under the new rules, you'll need to apportion your profits from two different accounting periods to determine your total taxable profits for the 2023/24 tax year.
This means you'll take the profits generated from 1 January 2023 to 5 April 2023 (from your 2023 accounts) and the business profits from 6 April 2023 to 31 December 2023 (from your 2024 accounts) to calculate your overall profit for the 2023/24 tax year.
This process of apportioning profits may require additional record-keeping and calculations, particularly in the transitional year (2023/24). It's essential to work closely with your accountant to ensure that your taxable profits are calculated accurately and that you're claiming all the allowable expenses and reliefs you're entitled to.

What About Overlap Relief?
Under the old basis period rules, some businesses may have paid tax on the same profits twice, resulting in what's known as overlap profits. This could occur when a business changed its accounting period or when a new sole trader or partnership started trading.
If you have overlap profits, you'll be able to claim overlap relief in the 2023/24 tax year to reduce your taxable profit. This is a one-time opportunity to use any accumulated overlap relief figure, and it's crucial to claim this relief, as any unused overlap relief will be lost after this tax year.
To claim overlap relief, you'll need to know the amount of overlap profits you have. This information should be available on your previous tax returns or your business records, such as the self-employment supplementary pages (SA103S or SA103F) of your self-assessment tax return.
If you're unsure about your overlap relief figure, consult your accountant, who can help you determine the correct amount and ensure that it's claimed properly on your tax return.

Transitional Rules for the 2023/24 Tax Year
To help businesses adjust to the new rules, there are special transitional rules in place for the 2023/24 tax year. This is because some businesses may find that they have more than 12 months' worth of profits to report in this transitional year due to the change in reporting periods.
Under the transitional rules, if your business has additional profits to report in the 2023/24 tax year (known as 'transition profits' or 'transitional profit'), you'll be able to spread these profits over five tax years (from 2023/24 to the 2027/28 tax year). This spreading of profits is designed to help manage your tax liability and avoid a significant one-off increase in your income tax and National Insurance contributions.
It's important to note that the transitional rules are optional, and you can choose to pay tax on all your transitional profit in the 2023/24 tax year if you prefer. However, for most businesses, spreading the profits over five tax years will be the most beneficial option, as it helps to smooth out your tax liability and maintain cash flow.
What Actions Should I Take?
As a business owner, it's essential to understand how basis period reform will affect your specific circumstances. We recommend reviewing your business accounts and speaking with your accountant to determine any changes you need to make when preparing your self-assessment tax return.
If your accounting period end doesn't currently align with the tax year, consider changing it to simplify your reporting under the new rules. While you're not obliged to change your accounting year-end date, aligning it with the tax year (5 April) can make the transition to the new rules smoother and reduce the need for apportioning profits in future tax years.
You should also start gathering the necessary information to calculate your taxable profits for the 2023/24 tax year, including details of your business income, allowable expenses, and any overlap relief you may be entitled to. Make sure to keep accurate records of all your business transactions, as this will make it easier to prepare accounts and complete your tax return under the new rules.
If you're unsure about any aspect of the new rules or how they apply to your business, don't hesitate to seek professional advice from your accountant or consult the detailed guidance provided by HMRC.
