The 31 January 2025 deadline for self-assessment tax returns is fast approaching. Avoid penalties and last-minute stress by filing your return and paying any tax due promptly. Don’t forget, first-time filers need to register for HMRC’s online service without delay.

You should also be aware that payment of any tax due should also be made by this date. This includes the remaining self-assessment balance for the 2023-24 tax year, as well as the first payment on account for the 2024-25 tax year.

A recent press release by HMRC has highlighted the fact that 4,409 taxpayers took the time to file their tax return online on Christmas Day with a further 11,932 taxpayers completing their tax returns on Boxing Day. In total, 40,072 self-assessment returns were filed between 24 and 26 December. The total number of submissions for the period was significantly more than in the previous year.

If you are filing online for the first time you should ensure that you register to use HMRC’s self-assessment online service as soon as possible. Once registered an activation code will be sent by mail. This process can take up to 10 working days.

If you miss the filing deadline then you will be charged a £100 fixed penalty (unless you have a reasonable excuse) which applies even if there is no tax to pay, or if the tax due is paid on time. There are further penalties for late tax returns still outstanding 3 months, 6 months and 12 months after the deadline. There are also additional penalties for late payment amounting to 5% of the tax unpaid at 30 days, 6 months and 12 months.

Are you a landlord? Maximise your rental income by knowing which expenses you can claim to reduce your tax bill. From maintenance costs to Replacement of Domestic Item Relief, understanding allowable deductions is key to smart property management.

If you are a landlord, it is important to be aware of the expenses that can and cannot be claimed from rental income. As a general rule, allowable expenses must be wholly and exclusively for the purpose of renting out the property. In some cases, a proportion of expenses can be claimed if part of the expense relates to the property business.

Common types of deductible revenue expenditure include:

• General maintenance and repairs to the property (but not improvements).
• Water rates, council tax, gas, and electricity.
• Insurance costs.
• Letting agent and management fees.
• Qualifying legal and accountancy fees.
• Direct costs such as phone calls, stationery, and advertising for new tenants.
• Vehicle running costs (only the proportion used for the rental business), including mileage rate deductions for business-related motoring costs.

Additionally, the Replacement of Domestic Item Relief allows landlords to claim tax relief when replacing furniture, furnishings, appliances, and kitchenware in a rented property, provided certain conditions are met.

Landlords should also keep a record of any capital expenditure incurred on investment properties. These expenses cannot be claimed as revenue expenditure against rental income but can usually be offset against Capital Gains Tax when selling a property.

Selling goods or services? It’s vital to know if HMRC considers this a business. From regular sales to earning commissions, their rules on ‘trading’ impact your tax obligations. Here’s a simple guide to help you stay compliant and avoid pitfalls.

If you are selling goods or services, you need to determine whether this constitutes a business. According to HMRC’s guidance, you are required to establish a business if you 'trade' in goods or services.

While not an exhaustive list, HMRC suggests you are likely to be considered as trading if you:

• sell regularly to make a profit
• make items to sell for profit
• sell items on a regular basis, either online, at car boot sales or through classified adverts
• earn commission from selling goods for other people
• are paid for a service you provide

If you only occasionally sell items then you are probably not trading. However, there is no statutory definition of ‘trade.’ The only statutory clarification is that ‘trade’ encompasses a ‘venture in the nature of trade.’ Consequently, the courts have defined what constitutes a ‘trade’ through their rulings, which serve as guidance when disputes arise.

In complex cases, HMRC may use 'badges of trade' tests to assess whether an activity is a legitimate business or just a money-making by-product of a hobby. While not definitive, these tests will help HMRC make this determination. In most cases, it will be clear if your trade in goods or services is a business.

The cash basis is now the default for self-employed income reporting. Learn about the key updates, opt-out options, and how this simplified method can ease your self-assessment obligations with HMRC.

The cash basis is used by sole traders and other unincorporated businesses to determine their income and expenses for self-assessment. This simplified method can ease record-keeping and income reporting to HMRC, whilst still providing a suitable measure of profits for many businesses.

Since 6 April 2024, the cash basis has become the default method for calculating income and expenses for self-employed individuals and partnerships when filing their Income Tax self-assessment return.

Businesses that prefer traditional accruals accounting or who are ineligible for the cash basis, must opt out of the cash basis when submitting their self-assessment return. The first return requiring this decision will be the 2024-25 return, due by 31 January 2026.

There have also been a number of other changes to the cash basis that took effect for the current 2024-25 tax year. This includes the following:

• The removal of the turnover thresholds for businesses to use the cash basis.
• The removal of the restrictions on using relief for losses made in the cash basis, aligning the rules with accruals.
• Interest restrictions have been removed so both cash basis and accruals accounting are subject to the same tax rules.
• People with more than one business will be able to choose whether they use the cash basis or accruals accounting for each business they have, rather than having to pick one method for all their businesses.

The cash basis is not available to limited companies and limited liability partnerships.

From April 2026, Making Tax Digital for Income Tax (MTD for ITSA) will transform tax compliance for businesses, self-employed individuals, and landlords, mandating digital record-keeping and online submissions. Get prepared!

The mandatory signup for Making Tax Digital (MTD) for Income Tax is set to commence from April 2026. MTD for ITSA will fundamentally change the way relevant businesses, the self-employed and landlords interact with HMRC. The regime will require businesses and individuals to register, file, pay and update their information using an online tax account.

The rules will initially apply to businesses, self-employed individuals and landlords with an income of over £50,000 annually. MTD for Income Tax will then be extended to those with an income between £30,000 and £50,000 from 6 April 2027. A new system of penalties for the late filing and late payment of tax for ITSA will also apply.

It was announced as part of the recent Autumn Budget measures that MTD for Income Tax will be extended to sole traders and landlords with income over £20,000 by the end of the current Parliament. The precise timing of this change has yet to be confirmed.

HMRC states that, MTD for Income Tax is a new way of reporting income and expenses if you’re a sole trader or landlord. You’ll need to:

• use software that works with Making Tax Digital for Income Tax;
• keep digital records of your business income and expenses;
• send us quarterly updates; and
• submit a tax return and pay tax due by 31 January the following year.

If you have volunteered to test the MTD for Income Tax service then the new late submission penalties and late payment penalties will apply. If you are looking to volunteer now then you will be required to confirm that you agree that the new penalties will apply to you as part of the sign-up process.

The new penalties apply as following during the testing phase.
