Basis period reform – spreading rules for payment

If your business has transitional profits from basis period reform, spreading over five years may reduce the cash flow impact, but it is important to understand the deadlines.

The self-employed basis period reform has changed the way trading income is allocated to tax years. Under these reforms, the basis of assessment moved from a current year basis to a tax year basis.

As a result, all sole traders and partnership businesses are now required to report their profits on a tax year basis. This change fully came into effect from the self-assessment return due by 31 January 2025, covering the 2023–24 tax year.

Under the old rules, businesses could have overlapping basis periods. This sometimes resulted in profits being taxed twice, with corresponding overlap relief usually given when the business ceased. The move to a tax year basis removed the basis period rules and prevented the creation of any new overlap relief.

The spreading rules for the payment of transitional profits are still available. By default, transition profits are spread evenly over five tax years, from 2023–24 to 2027–28, helping to ease cash-flow pressures. Taxpayers can also elect to accelerate the taxation of transition profits if they wish, but spreading continues to apply automatically unless an election is made.

If your business ceases on or before 5 April 2027, any transition profit remaining after overlap relief that has not yet been taxed must be brought into charge in the final year of trading.

Spring Statement 2026

The Chancellor, Rachel Reeves has confirmed that she will deliver the Spring Statement to the House of Commons on Tuesday, 3 March 2026.

The Spring Statement is used to give an update on the state of the economy and will respond to the economic and fiscal forecast published by the Office for Budget Responsibility (OBR). The Spring Statement also presents an opportunity for the government to publish consultations, including initiating early-stage calls for evidence and consultations on long-term tax policy issues.

The OBR has executive responsibility for producing the official UK economic and fiscal forecasts, evaluating the government’s performance against its fiscal targets, assessing the sustainability of and risks to the public finances and scrutinising government tax and welfare spending.

Usually, major policy and tax changes are announced at the Budget, and it remains to be seen whether there will be any significant announcements in the upcoming Spring Statement. The next Budget is expected to take place later this year in the Autumn.

Saving tax using the Marriage Allowance

If one partner earns under £12,570, you could transfer part of their unused personal allowance and cut your tax bill by up to £252 a year.

The Marriage Allowance applies to married couples and civil partners where one partner does not pay Income Tax, usually because their income is below the personal allowance. For the 2025–26 tax year, this means the lower-earning partner must earn less than £12,570.

The allowance means the lower-earning partner can transfer up to £1,260 of their unused personal allowance to their spouse or civil partner. This transfer is only permitted if the recipient is taxed at no more than the basic rate of Income Tax. This means the higher-earning partner must usually have an income between £12,571 and £50,270. For those living in Scotland, this generally applies where income does not exceed £43,662, which is the point at which the Scottish higher rate begins.

By using the allowance, up to £1,260 of unused personal allowance can be transferred, resulting in a tax saving of up to £252 per year for the higher-earning partner, calculated at 20% of the amount transferred.

If you meet the eligibility criteria and have not yet claimed the Marriage Allowance, you can backdate your claim for up to four previous tax years. At present, claims can be backdated to the 2021–22 tax year, meaning you may be able to claim for 2021–22, 2022–23, 2023–24, 2024–25 and the current 2025–26 tax year. This could result in a total tax saving of up to £1,260 across those years. Claims, including backdated claims and applications for the current year, can be made online via GOV.UK.

Selling a second property?

CGT on certain UK residential property sales often has a strict 60-day reporting and payment deadline, so early planning can avoid penalties.

If you are selling a second property, such as a buy-to-let or a former home that is no longer your main residence, CGT will usually apply. This is different from selling your main home, which is often covered by Principal Private Residence (PPR) relief and therefore exempt from CGT.

The annual exempt amount applicable to Capital Gains Tax (CGT) is currently £3,000. CGT is normally charged at a simple flat rate of 24% and this applies to most chargeable gains made by individuals. If taxpayers only pay basic rate tax and make a small capital gain, they may only be subject to a reduced rate of 18%. Once the total of taxable income and gains exceed the higher rate threshold, the excess will be subject to 24% CGT. 

Most homeowners do not pay CGT when selling their main family home, as PPR relief usually applies. However, CGT is commonly payable on gains from:

  • Buy-to-let properties
  • Second homes or holiday homes
  • Business premises
  • Land
  • Inherited property (based on the increase in value since inheritance, not since original purchase)

Any CGT due on the sale of UK residential property must usually be reported and paid within 60 days of completion. This requires submitting a UK Property CGT return and making a payment on account within that timeframe.

Failing to meet the 60-day deadline can result in penalties and interest, so it is important to plan ahead and obtain advice as early as possible when selling a property that is not fully exempt.

Annual payroll reporting chores

There are a number of annual payroll reporting issues that employers are required to complete. With the tax year ending on 5 April 2026, this means there are several key payroll reporting chores that will need to be considered over the coming months.

One of the main requirements is submitting a final PAYE return for the tax year. The final Full Payment Submission (FPS) must be sent to HMRC on or before employees’ final payday in the 2025–26 tax year to ensure payroll records are correctly closed for the year.

Employers must also remember to provide employees with a P60 by 31 May 2026. A P60 must be issued to all employees who are on the payroll on the final day of the tax year, 5 April 2026. The P60 summarises an employee’s total pay and the tax deducted during the year and can be provided either in paper form or electronically.

Employees should be advised to keep their P60s safe, as they are an important record of tax paid and may be needed to reclaim overpaid tax, apply for tax credits, or provide evidence of income when applying for a loan or mortgage. Employees who leave during the tax year will not receive a P60, as the relevant information will already have been provided on their P45.

In addition, employers must report any Class 1A National Insurance contributions and submit P11D and P11D(b) forms to HMRC for the tax year ending 5 April 2026. The deadline for these submissions is 6 July 2026.
