The UK's shift to the Foreign Income and Gains (FIG) regime from April 2025 changes how foreign income is taxed. If you are a UK resident, get ready to possibly pay UK Income Tax on all foreign earnings—no more non-dom remittance basis.

UK Income Tax is generally payable on taxable income received by individuals including earnings from employment, earnings from self-employment, pensions income, interest on most savings, dividend income, rental income and trust income. The tax rules for foreign income can be very complex.

However, as a general rule if you are resident in the UK you need to pay UK Income Tax on your foreign income, such as:

• wages if you work abroad
• foreign investments and savings interest
• rental income on overseas property
• income from pensions held overseas

Foreign income is defined as any income from outside England, Scotland, Wales and Northern Ireland. The Channel Islands and the Isle of Man are classed as foreign.

If you are not UK resident, you do not generally have to pay UK tax on your foreign income. There are special rules if you work both in the UK and abroad.

The remittance basis rules which allowed non-UK domiciled individuals (often referred to as non-doms) to be taxed only on UK income and gains, is being abolished. From 6 April 2025, the concept of domicile as a relevant connecting factor in the UK tax system has been replaced by a new residence-based regime known as the Foreign Income and Gains (FIG) regime. 

HMRC has launched a new "Help for Hustlers" campaign to help people who are earning extra income, figure out if they need to pay tax on the additional earnings. The campaign runs until the end of March and focuses on five key areas where tax might apply:

1. I’m buying or making things to sell.
2. I’ve got a side gig.
3. I work for myself with multiple jobs.
4. I’m a content creator or influencer.
5. I rent out my property.

The good news is there are two £1,000 tax allowances — one for property income and one for trading income. If you have both types of income, you can claim £1,000 for each.

• Trading Allowance: If you make up to £1,000 from self-employment, casual services (like babysitting or gardening), or renting out personal equipment (such as power tools), this income is tax-free and does not need to be declared.
• Property Allowance: If you earn £1,000 or less from property-related activities (like renting out a driveway), you do not need to report it to HMRC or include it in your tax return.

These allowances cover all relevant income before expenses. If your income is under £1,000, it’s tax-free. If you earn more than £1,000, you can choose to either deduct the £1,000 allowance from your income or list your actual expenses when calculating your taxable profit.

However, if your side hustle income goes over £1,000 in a tax year, you may need to complete a self-assessment tax return. Keep in mind this only applies if you are actively trading or selling services. If you are just clearing out some old stuff and selling it, there is usually no need to worry about tax.

Tax on rental income from jointly owned property depends on ownership shares, unless part of a partnership. Married couples default to a 50/50 split unless they notify HMRC of a different income allocation based on actual ownership proportions.

When property is jointly owned with one or more individuals, the taxation of rental income depends on whether the rental activity is considered a partnership. Simply owning property together does not automatically qualify the arrangement as a partnership.

If the jointly owned property is not part of a partnership, the allocation of any profit or loss from the jointly owned property is typically based on each person's ownership share in the property. However, the co-owners can agree to divide the profits and losses differently than their ownership proportions, so it’s possible for one person to receive a larger or smaller share of the profits or losses than their share in the property itself. For tax purposes, the profit and loss share must reflect the actual agreement made by the owners.

In cases where the joint owners are married or in a civil partnership, the profits and losses are generally treated as being divided equally between them, unless:

• The entitlement to the income and the ownership of the property are split unequally between the spouses or civil partners, and
• Both parties must inform HMRC that they wish the division of profits and losses to align with their respective ownership shares in the property.

If these conditions are met, the profit and loss distribution will follow the agreed-upon ownership percentages, rather than the default equal split for married couples or civil partners.

Over 11.5 million people met the 31 January 2025 self-assessment deadline, but 1.1 million taxpayers missed it. If you're one of them, expect a £100 penalty. Learn about late fees and HMRC’s payment plan options to avoid further charges.

There are an estimated 1.1 million taxpayers that missed the deadline. Are you among those that missed the 31 January 2025 filing deadline for your 2023-24 self-assessment returns?

If you have missed the filing deadline then you will usually be charged a £100 fixed penalty if your return is up to 3 months late, regardless of whether you owed tax or not. If you do not file and pay before 1 May 2025 then you will face further penalties unless you have arranged to pay with HMRC.

If you are unable to pay your tax bill, there is an option to set up an online time to pay payment plan to spread the cost of tax due on 31 January 2025 for up to 12 months. This option is available for debts up to £30,000 and the payment plan needs to be set up no later than 60 days after the due date of a debt.

If you owe self-assessment tax payments of over £30,000 or need longer than 12 months to pay in full, you can still apply to set up a time to pay arrangement with HMRC, but this cannot be done using the online service.

Big changes are here for the self-employed! From 2024-25, profits must align with the tax year, replacing the old "current year basis." Overlap relief is ending, and transition profits will be spread over five years. Here’s how the new system affects your tax bill.

The reform to the self-employed tax basis period has introduced significant changes in how trading income is allocated to tax years. Previously, the tax basis period operated on a "current year basis," but the reform has now shifted to a "tax year basis." As a result, all sole traders and partnership businesses are required to report their profits based on the tax year, commencing with the self-assessment return that was due by 31 January 2025. This return covered the tax year 2023-24.

Under the previous system, overlapping basis periods could occur, which resulted in certain profits being taxed twice. To counter this, businesses could claim ‘overlap relief,’ typically at the time of business cessation. The introduction of the "tax year basis" eliminates the possibility of overlapping basis periods, thereby preventing the generation of further overlap relief.

It is important to note that businesses which already prepare annual accounts to a date between 31 March and 5 April are not affected by these changes. These businesses continue to file their tax returns as they did under the old system, without any alteration.

The full implementation of the new rules takes effect in the current 2024-25 tax year, which ends on 5 April 2025. The 2023-24 tax year is considered a "transition year." During this transitional period, the basis periods for all businesses will be aligned with the tax year, and any outstanding overlap relief can be utilised against profits for that period.

In cases where profits exceed the period covered by the overlap relief—specifically profits that span more than 12 months—these are referred to as "transition profit." This transition profit will, by default, be spread across five tax years, from 2023-24 to 2027-28, to help ensure a smooth adjustment to the new rules.

Your tax code determines how much tax is deducted from your pay. While 1257L is the most common, different letters and numbers can affect how much you owe. From marriage allowance to emergency codes, here’s how to decode what HMRC assigns you.

Your tax code is basically a set of letters and numbers that show whether you are entitled to the annual tax-free personal allowance (the amount you can earn without paying tax). These codes are updated each year and help your employer figure out how much tax to take off your pay.

For the current and next tax years, the standard personal allowance is £12,570, and if you are entitled to this, your tax code will likely be 1257L. This is the most common code and applies to people with one job, no untaxed income, and no taxable benefits like a company car.

But tax codes are not always that straightforward. There are all sorts of other letters and numbers that might pop up. For example, if you are claiming the marriage allowance, your code might have an "M" in it. If you are paying tax at the Scottish rates, your code will start with an "S." And if your personal allowance gets reduced for some reason, like unpaid tax or income adjustments, your code will change accordingly.

Then there are the emergency tax codes—W1 or M1—which are used when someone starts a new job and does not have a P45 yet. These codes mean your tax will be calculated based on just that specific pay period, rather than your full income.

If you spot a 'K' at the start of your tax code, it means deductions (for things like company benefits, state pension, or previous tax owed) are greater than your personal allowance. Your tax deduction won’t be more than half of your pay or pension.

From 6 April 2025, the remittance basis of taxation will be scrapped in favour of a residence-based system. A new 4-year Foreign Income and Gains regime offers tax relief for new arrivals, while transitional measures aim to ease the shift. Here’s what’s changing.

Effective from 6 April 2025, the remittance basis of taxation for non-UK domiciled individuals will be replaced by a simplified, residence-based tax regime.

Additionally, the government will introduce a 4-year Foreign Income and Gains (FIG) regime. Under this regime, individuals newly arriving in the UK who choose to participate will receive full relief (100%) on foreign income and gains during their first four years of UK tax residence, provided they have not been UK tax resident in any of the preceding 10 consecutive years.

As a transitional measure for Capital Gains Tax (CGT) purposes, individuals who have previously used the remittance basis will have the option to rebase personally held foreign assets to their value as of 5 April 2017, provided certain conditions are met.

Furthermore, Overseas Workday Relief will be extended to cover a 4-year period, in line with the new 4-year FIG regime. This change will eliminate the need for individuals using this relief to keep their employment income offshore. From 6 April 2025, the maximum amount of Overseas Workday Relief that can be claimed annually will be the lesser of £300,000 or 30% of the individual's net employment income.

A new Temporary Repatriation Facility (TRF) will also be introduced from April 2025 for a 3-year period. This facility will allow individuals who have previously been taxed on the remittance basis to designate and remit foreign income and gains that arose prior to the reform, at a reduced rate. This includes foreign income and gains held within trust structures that have not been attributed. The TRF will offer a rate of 12% for the first 2 years, and 15% in the final year of its operation.

Gift Aid transforms charitable donations by allowing charities and CASCs to claim 25p extra for every £1 given—at no additional cost to you. Higher and additional rate taxpayers can also claim valuable tax relief, making giving even more rewarding.

Higher and additional rate taxpayers can claim tax relief on the difference between the basic rate of tax and their highest rate. This can be done through their self-assessment tax return or by requesting HMRC to adjust their tax code.

Example: 

If a taxpayer donates £1,000 to charity, the total value of the donation to the charity is £1,250. The taxpayer can claim additional tax relief based on their tax rate:

• £250 if they pay tax at 40% (£1,250 × 20%)
• £312.50 if they pay tax at 45% (£1,250 × 25%)

It is important to ensure that the taxpayer has paid enough tax in the relevant year. Donations will qualify for tax relief as long as the total claimed does not exceed four times the amount of tax paid in that year. If more tax relief is claimed than entitled, the taxpayer must notify the charity and repay the excess to HMRC.

Additionally, taxpayers can make donations directly from their wages through a payroll giving scheme if their employer operates one approved by HMRC. This allows donations to be made tax-free from salary or pension payments.

Changes to the High Income Child Benefit Charge (HICBC) came into effect on 6 April 2024. The income threshold at which HICBC starts to be charged increased to £60,000 (from £50,000).

The charge is calculated at 1% of the full Child Benefit award for every £200 (2023-24: £100) of income between £60,000 and £80,000. (2023-24: between £50,000 and £60,000). For taxpayers with income above £80,000 (2023-24: £60,000) the amount of the charge is the same as the amount of Child Benefit received. The HICBC therefore either reduces or removes the financial benefit of receiving Child Benefit.

For new Child Benefit claims made after 6 April 2024, any backdated payment will be treated for HICBC purposes as if the entitlement fell in the 2024-25 tax year if backdating would otherwise create a HICBC liability in the 2023-24 tax year.

Even if HICBC applies to you or your partner, it’s generally still beneficial to claim Child Benefit as doing so can safeguard certain benefits and ensure your child receives a National Insurance number. Claims can be made by using the HMRC app or online resources. New claims are automatically backdated for up to 3 months or to the child’s birth date if later.

Taxpayers can choose to continue receiving Child Benefit – and pay the tax charge – or opt to stop receiving benefits and avoid the charge.

HMRC’s Personal Tax Accounts (PTAs) serve as an online tool that enables taxpayers to view and update their information in real time. The PTA can be used for many routine requests and services and help you bypass the need to call or write to HMRC.

Every individual in the UK that pays tax has a PTA, but taxpayers must sign up in order to access and use the service. This can be achieved by using the Government Gateway. You may need to verify your identify when using the service.

The following services are currently available on your PTA:

• check your Income Tax estimate and tax code
• fill in, send and view a personal tax return
• claim a tax refund
• check your Child Benefit
• check your income from work in the previous 5 years
• check how much Income Tax you paid in the previous 5 years
• check and manage your tax credits
• check your State Pension
• check if you’ll benefit from paying voluntary National Insurance contributions and if you can pay online
• track tax forms that you’ve submitted online
• check or update your Marriage Allowance
• tell HMRC about a change of name or address
• check or update benefits you get from work, for example company car details and medical insurance
• find your National Insurance number
• find your Unique Taxpayer Reference (UTR) number
• check your Simple Assessment tax bill

The PTA is a key component of HMRC’s broader strategy to transition to a fully digital tax service.
