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.

If your company profits sit between £50,000 and £250,000, marginal relief can soften the jump from 19% to 25% Corporation Tax.

The Corporation Tax main rate applies to companies with taxable profits above £250,000 and is currently set at 25%. Companies with profits of up to £50,000 are subject to the Small Profits Rate, which remains at 19%.

For companies with profits falling between £50,000 and £250,000, marginal relief applies. This creates a gradual increase in the effective rate of Corporation Tax between the small profits and main rates, rather than a sudden jump. The lower and upper profit limits are proportionately reduced where an accounting period is shorter than 12 months or where a company has associated companies.

The effect of marginal relief is that the effective Corporation Tax rate increases steadily from 19% once profits exceed £50,000, reaching the full 25% rate when profits exceed £250,000.

In practice, Corporation Tax is calculated by applying the main rate of 25% to total taxable profits and then deducting the marginal relief due. The marginal relief standard fraction is 3/200. HMRC provides an online marginal relief calculator to help companies determine the correct amount of Corporation Tax payable based on their profit level and circumstances.

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.

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.

With the balancing payment and first payment on account both due on 31 January 2026, it is worth checking your options early if funds are tight.

The final balancing payment for the 2024–25 tax year is due by 31 January 2026, which is also the deadline for filing your self-assessment tax return. This payment will settle any remaining tax owed for the year after taking account of payments on account already made.

In addition to the balancing payment, many self-assessment taxpayers will also have a first payment on account for the 2025–26 tax year due on the same date, which can make January a particularly challenging month for cash flow.

If you are struggling to meet the tax payments due by 31 January 2026 deadline, it is important to take action early, as there are options available to help manage the payment.

Taxpayers with self-assessment liabilities of up to £30,000 can use HMRC’s online Time to Pay (TTP) service to set up instalment payments. This can be done without speaking directly to an HMRC adviser and is available up to 60 days after the payment deadline.

To use the online Time to Pay service, you must:

• Have no outstanding tax returns
• Have no other unpaid tax debts
• Have no existing HMRC payment plans

If you do not meet these criteria, it may still be possible to agree a bespoke Time to Pay arrangement by contacting HMRC directly. These arrangements are assessed on a case-by-case basis and are usually based on your personal or business financial position.

HMRC will generally agree to extended payment terms where they believe the tax can be paid in full over time. However, if HMRC considers that delaying payment will not resolve the issue, they may seek immediate payment and can take enforcement action if the debt remains unpaid.

If you anticipate difficulty in paying your January 2026 tax bill, please do not ignore the problem. Please let us know and we can help you understand what options are available to you.
