For the current tax year, taxpayers with adjusted net income between £100,000 and £125,140 will face an effective marginal tax rate of 60%, as their £12,570 tax-free personal allowance is gradually withdrawn.

If a taxpayer earns over £100,000 in any tax year, their personal allowance is gradually reduced by £1 for every £2 of adjusted net income exceeding £100,000. This ceiling applies regardless of age, meaning that any taxable receipt that pushes their income above this threshold will lead to a reduction in their personal tax allowances. If their adjusted net income reaches £125,140 or more, the personal Income Tax allowance will be reduced to zero.

Adjusted net income refers to a taxpayer’s total taxable income before personal allowances, minus certain tax reliefs such as trading losses, charitable donations, and pension contributions.

Taxpayers in this income band should consider financial planning strategies to avoid this "personal allowance trap." Reducing income below £100,000 could be achieved by utilising options like increasing pension contributions, making charitable donations, or participating in certain investment schemes.

For higher-rate or additional-rate taxpayers seeking to reduce their tax bill, gifting to charity is one strategy. Donations made in the current tax year can be carried back to the 2024-25 tax year, provided the taxpayer requests the carry-back before or at the same time as submitting their self-assessment return, but no later than 31 January 2026.

Married couples and civil partners could save up to £252 a year by transferring part of one partner’s unused personal allowance to the other, but you may need to cancel the claim if your income or relationship status changes.

The Marriage Allowance applies to married couples and civil partners where one partner does not pay tax or does not pay tax above the basic rate threshold for Income Tax (i.e., one partner must earn less than the £12,570 personal allowance for 2025-26).

The allowance allows the lower-earning partner to transfer up to £1,260 of their unused personal tax-free allowance to their spouse or civil partner. The transfer can only be made if the recipient (the higher-earning partner) is taxed at the basic 20% rate, which typically means they have an income between £12,571 and £50,270. For those living in Scotland, this would usually apply to an income between £12,571 and £43,662.

By using the allowance, the lower-earning partner can transfer up to £1,260 of their unused personal allowance, which could result in an annual tax saving of up to £252 for the recipient (20% of £1,260).

However, it is important to be aware you must cancel the Marriage Allowance if your circumstances change and any of the following apply:

As of April 2025, directors of close companies and self-employed taxpayers face new mandatory reporting requirements on their Self-Assessment returns.

Up to 900,000 company directors and 1.2 million taxpayers carrying on a trade will be impacted by new rules that require them to provide more information when filing their 2025-26 self-assessment returns.

Legislation has been enacted that introduces mandatory reporting obligations for certain taxpayers, including those who begin or cease trading and directors of close companies. These measures came into effect on 5 April 2025 and apply for the current 2025-26 tax year and later tax years.

Company directors of close companies will face new reporting requirements. Most small private companies will meet the definition of a close company and there are some specific tax rules that apply to these companies. From 5 April 2025, taxpayers impacted by the change must confirm whether they are directors of a close company and provide further details, including the company’s name and registered number, the value of dividends received and their percentage shareholding in the company. If shareholding changes during the year, the highest percentage held must be reported. Answering these questions will be mandatory when submitting 2025-26 tax returns and beyond.

The new rules also introduce a mandatory requirement to report the start or cessation of a trade that was previously a voluntary requirement. Taxpayers are now required to include the date of commencement or cessation of their business in their tax return, whether for personal tax, partnerships or trustees. This change applies to tax returns for 2025-26 and beyond.

Paper tax returns are due 31 October 2025, and new registrants must notify HMRC by 5 October 2025. Act early to avoid penalties.

Firstly, the deadline for submitting paper self-assessment tax returns is 31 October 2025. If you miss this deadline a £100 late filing penalty will usually apply, even if no tax is due, or if any tax owed is paid in full by the final deadline of 31 January 2026.

Further penalties increase the longer the return remains outstanding. If your return is still not filed three months after the deadline, daily penalties of £10 per day (up to a maximum of £900) will be charged. If the delay extends to six months or more, further fixed or percentage-based penalties may apply, significantly increasing the cost of non-compliance.

We strongly recommend that anyone still submitting paper returns consider switching to the online filing system. Filing electronically not only simplifies the process but also gives you an extra three months, with the deadline for online returns falling on 31 January 2026.

The second key deadline is 5 October 2025. This is the date by which you must notify HMRC if you need to complete a self-assessment return for the 2024–25 tax year and have not previously been required to file one. Failing to register in time can lead to penalties for late notification, even if you file your return on time later.

Being aware of these October deadlines and taking timely action can help you avoid unnecessary stress and potential fines if you were unprepared.

Homeowners can earn up to £7,500 tax-free under the rent-a-room scheme, with simple reporting and flexible tax options.

This set of special rules is designed to encourage individuals to make use of spare space in their property by providing a tax exemption on rental income of up to £7,500 per tax year.

If the total rental income from lodgers does not exceed the £7,500 threshold, the exemption applies automatically, with no need to file a tax return or report the income to HMRC. This makes the scheme particularly appealing for those seeking a simple way to supplement their income without added paperwork. However, if you prefer, you can opt out of the scheme and instead declare property income and expenses in the usual way.

The relief is only available for furnished accommodation and typically applies when a homeowner rents out a bedroom to a lodger within their main residence. One of the key benefits of the scheme is that it not only allows for tax-free earnings up to the threshold but also reduces the overall tax and administrative burden for participants. If the property is jointly owned and both parties receive rental income, the £7,500 limit is halved to £3,750 per person.

It is important to note that the rent-a-room limit covers not just rent, but also any additional payments received for meals, laundry, or cleaning services provided to the lodger. If your gross receipts exceed the threshold, you have a choice: you can either pay tax on the actual profit (gross rents minus allowable expenses and capital allowances) or choose to be taxed on the total gross receipts minus the £7,500 allowance, with no deduction for expenses or allowances. This flexibility helps taxpayers to choose the most tax-efficient method depending on their specific circumstances.

The standard tax treatment for couples living together, whether married or in a civil partnership, is that income from jointly held property is split equally (50:50) between them, regardless of their actual ownership shares.

However, if the ownership is unequal and the couple wishes to have the income taxed in proportion to their respective beneficial interests, they must formally notify HMRC. This is done by submitting HMRC’s Form 17, which declares the true beneficial ownership split of the property and the associated income.

A Form 17 declaration can only be submitted by spouses or civil partners who are living together and jointly own property in unequal shares. It does not apply to unmarried couples, those who are separated, or other relationship types.

The declaration must be agreed upon and signed by both parties. If one partner does not consent, the income will continue to be taxed on a 50:50 basis, regardless of how the property is actually owned.

Once accepted by HMRC, a Form 17 declaration remains effective until there is a change in the couple’s relationship status (e.g., separation or divorce) or in the ownership structure of the property. In such cases, the default 50:50 split will be reinstated.

It is important to note that Form 17 cannot be used in certain situations—for example, when property is owned as beneficial joint tenants, or where the income derives from shares in a close company or a business partnership.

Where applicable, submitting Form 17 can provide valuable tax advantages by aligning the taxation of property income with the actual economic ownership.

Speculation is growing that rates or allowances applied to dividend income may change in the next Budget.

The current tax rates for dividends received (in excess of the £500 dividend tax allowance) are as follows:

Dividends that fall within your Personal Allowance do not count towards your dividend allowance and you may pay tax at more than one rate.

If you receive up to £10,000 in dividends you can ask HMRC to change your tax code and the tax due will be taken from your wages or pension or you can enter the dividends on your self-assessment tax return, if you already fill one in. You do not need to notify HMRC if the dividends you receive are within your dividend allowance for the tax year.

If you have received over £10,000 in dividends, you will need to complete a self-assessment tax return. If you do not usually send a tax return, you need to register by 5 October following the tax year in which you had the relevant dividend income.

There has been growing speculation ahead of the upcoming Budget that the government could make further changes to the taxation of dividends. With the government under pressure to raise revenue there is the possibility that the rates of dividend taxes could be increased. The current £500 tax‑free dividend allowance could also be abolished altogether, after having been significantly reduced over the last number of years.

The letters in your tax code indicate whether you are entitled to the annual tax-free personal allowance. These codes are updated each year and help employers calculate how much tax should be deducted from your salary.

For the current tax year, the basic personal allowance is £12,570. The tax code corresponding to this amount is 1257L, which is the most common tax code used for those with a single job, no untaxed income, and no unpaid tax or taxable benefits (such as a company car).

HMRC updates your tax code when your circumstances change, and your taxable income is affected. Some common reasons why your tax code may change include:

It is important to check your tax code is correct. If you have any questions, we would be happy to help.

From 2024, platforms like eBay, Vinted and Airbnb must report seller data to HMRC, so check your tax responsibilities.

If you sell goods or services on a digital platform it is important to understand your tax responsibilities. This can apply whether your sales are a part-time income source or your main income. Even casual selling online may mean you need to report earnings and potentially pay tax.

You may need to pay tax if you engage in activities on digital platforms like:

Since 1 January 2024, digital platforms (such as eBay, Vinted, Etsy and Airbnb) have been required to collect and report seller data to HMRC. The first reports covered the period from 1 January to 31 December 2024, with information submitted to HMRC by 31 January 2025.

The same rules apply in 2025, meaning income earned this calendar year (January to December 2025) will be reported by 31 January 2026.

Platforms must report your information if either of the following applies:

The digital platforms will also give you a copy of the data they send to HMRC, which can help when completing your self-assessment return.

If you are earning money online you should ensure you check your tax responsibilities. The rules are clear, and platforms are now required to report many types of earnings directly to HMRC.

Income Tax applies to earnings, pensions, savings, dividends and more, with different bands across the UK nations.

Individuals can be liable to Income Tax at any age. There are special rules to stop parents avoiding tax by putting assets into their children’s names.

The tables below shows the tax rates you pay in each band if you have a standard Personal Allowance of £12,570.

Bands: England, Northern Ireland and Wales    
Band    Taxable income Tax rate
Personal Allowance   Up to £12,570  0%
Basic rate £12,571 to £50,270 20%
Higher rate £50,271 to £125,140 40%
Additional rate over £125,140 45%

 

Bands: Scotland    
Band    Taxable income Tax rate
Personal Allowance   Up to £12,570  0%
Starter rate £12,571 to £15,397 19%
Basic rate £15,398 to £27,491 20%
Higher rate £43,663 to £75,000 42%
Advanced rate £75,001 to £125,140 45%
Top rate over £125,140 48%

If you earn over £100,000 in any tax year your personal allowance is gradually reduced by £1 for every £2 of adjusted net income over £100,000 irrespective of age. This means that any taxable receipt that takes your income over £100,000 will result in a reduction in personal tax allowances. This means your personal Income Tax allowance would be reduced to zero if your adjusted net income is £125,140 or above.

For the current tax year if your adjusted net income is likely to fall between £100,000 and £125,140 you would pay an effective marginal rate of tax of 60% as your £12,570 tax-free personal allowance is gradually withdrawn.

If your income sits within this band you should consider what financial planning opportunities are available in order to avoid this personal allowance trap by trying to reduce your income below to £100,000.
