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.

Over one million parents have now claimed Child Benefit online or via the HMRC app, with 87% of new claims using this speedy service. If you've recently had a baby or a child joins your family, applying online ensures you get support quickly—right when you need it most.

HMRC’s Director General for Customer Services, said:

"Having a baby is a busy and expensive time but claiming Child Benefit online or via the app means you’ll get cash in your bank account as soon as possible. Claim now and you could get your first payment in time for your baby’s first Christmas. Download the HMRC app today."

You can apply for Child Benefit starting the day after you register your child’s birth or when a child comes to live with you. Claims can be backdated up to 12 weeks. Applying online is usually the fastest way to complete your claim.

If you are unable to claim online, you can complete the Child Benefit form CH2 and send it to the Child Benefit Office. The address can be found on the form. If you are claiming for more than two children, you will need to complete the additional child form CH2(CS) and send it with your CH2 form. Alternatively, you can contact HMRC by phone if online or postal methods are not suitable.

Child Benefit is typically available for children who move to the UK. However, there are certain requirements that must be met to claim. If a child receiving Child Benefit moves permanently abroad, HMRC must be notified as soon as possible.

The child benefit rates for the only or eldest child in a family is currently £25.60 a week and the weekly rate for all other children is £16.95. The rates are set to increase to £26.05 and £17.25 respectively from April 2025.

Can’t pay your tax bill in full by 31 January 2025? HMRC’s online Time to Pay system lets self-assessment taxpayers spread the cost over monthly instalments. With plans available for tax bills up to £30,000, this flexible option can help you avoid late payment penalties.

 Those eligible for the self-serve option can arrange payments online without needing to contact an HMRC adviser. HMRC has revealed that more than 15,000 taxpayers have already set up a Time to Pay payment plan for the 2023-24 tax year.

To qualify for the online Time to Pay option, taxpayers must meet these conditions:

• No outstanding tax returns
• No other tax debts
• No existing HMRC payment plans

For taxpayers who do not meet these requirements or owe more than £30,000, other payment arrangements may be available. These are typically agreed on a case-by-case basis, tailored to individual circumstances and liabilities, allowing businesses and individuals to pay off their debt over time.

HMRC’s Director General for Customer Services, said:

We’re here to help customers get their tax right and if you are worried about how to pay your self-assessment bill, help and support is available. Customers can set up their online payment plan to suit their own financial circumstances and can spread those payments across a maximum of 12 months. It is a valuable option for someone needing extra flexibility in meeting their tax obligations.

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 and upcoming 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).

Your tax code might include various other letters and numbers. For instance, letters like "M" indicate that an employee is claiming the marriage allowance, or "S" shows that Scottish income tax rates apply. If your tax code numbers change, it often means your personal allowance has been reduced.

There are also emergency tax codes (W1 or M1), which are used when a new employee does not have a P45. These codes calculate tax based on the current pay period.

If your tax code starts with a 'K', this means deductions for company benefits, state pension, or previous tax owed, exceed your personal allowance. However, the tax deduction for any pay period cannot exceed half of your pre-tax salary or pension.

It is essential to verify your tax code to ensure the correct information is being applied. If you have any questions, we are here to help.
