Filing your 2024-25 Self-Assessment return early means faster refunds, better budgeting, and no deadline stress. Do not delay, start gathering your tax details today.

The 2024–25 tax year officially ended on 5 April 2025, with the new 2025–26 tax year beginning on 6 April 2026. While many taxpayers may be tempted to put off dealing with their self-assessment tax return until later this year, or early next year, there are several compelling reasons why filing early makes sense.

HMRC recently reported that nearly 300,000 people submitted their 2024–25 self-assessment returns during the first week of the new tax year, almost ten months before the 31 January 2026 filing deadline.

Filing early doesn’t mean paying early. However, by preparing and submitting your tax return well in advance, you gain the advantage of knowing exactly what you’ll owe by the 31 January deadline. This can be incredibly helpful for budgeting and avoiding any last-minute financial surprises.

Submitting your return early gives your accountant more time to work through the details without the pressure of a looming deadline. If you are due a tax refund, the sooner your return is filed and processed, the sooner you'll receive your money.

The 31 January 2026 is not just the final date for submission of the 2024-25 self-assessment tax return but also an important date for payment of tax due. This is the final payment deadline for any remaining tax due for the 2024-25 tax year. In addition, the 31 January 2026 is also the usual payment date for any Capital Gains Tax due in relation to the 2024-25 tax year and also the due date for the first payment on account for 2025-26. Note that any CGT due on the sale of a second residential property must be paid within 60 days of the sale, not in the following January.

In summary, filing your tax return early offers a clearer financial picture, helps spread the workload, and ensures you’re not caught out by deadlines. If you are due a refund, there’s no reason to wait as filing early means a quicker refund.

MTD for Income Tax starts 6 April 2026 for the self-employed and landlords with £50k+ income. Plan early to stay compliant and avoid disruption.

MTD represents one of the most significant overhauls to the self-assessment regime since its introduction in 1997. This includes new requirements to keep digital records, using MTD-compatible software, and submitting quarterly updates of income and expenses to HMRC.

From April 2026, self-employed individuals and landlords with annual qualifying business or property income over £50,000 will be required to comply with the MTD for Income Tax rules. Qualifying income includes gross income from self-employment and property before any tax allowances or expenses are deducted.

This first rollout of MTD for Income Tax will affect approximately 780,000 taxpayers, with the next stage following in April 2027, extending the rules to those earning between £30,000 and £50,000. A further expansion, announced during the Spring Statement 2025, will apply MTD obligations to those with income over £20,000 from April 2028. The government is still considering the best approach for individuals earning below this lower threshold.

HMRC is asking some eligible taxpayers to sign up to its MTD testing programme on GOV.UK. This provides an opportunity to get comfortable with the new process before it becomes mandatory. Importantly, penalties for late submissions will not apply during the testing phase.

This move follows the rollout of MTD for VAT, which according to an independent report prepared for HMRC has helped over two million businesses improve accuracy and reduce errors.

As the deadline approaches, it is important to start planning in order to ensure a smooth transition to the new way of reporting Income Tax.

The £3,000 reporting threshold for trading, property, and other income will simplify tax returns—300,000 people could be freed from filing. A digital alternative is also coming.

As part of the Spring 2025 Tax Update: Simplification, Administration and Reform, the government confirmed changes to the Income Tax Self Assessment (ITSA) reporting thresholds for trading, property, and other taxable income. From a future date within this Parliament, these thresholds will all be aligned and increased to £3,000 (gross) each.

This reform is designed to streamline the tax system and reduce unnecessary reporting. As a result, up to 300,000 taxpayers will no longer be required to submit a self-assessment return if their taxable income falls below the new threshold. Of those affected, an estimated 90,000 individuals will have no tax to pay at all and will not need to report their trading income to HMRC in the future.

For those with income below the threshold who do have tax to pay, a new digital reporting service will be introduced, offering a simpler alternative to self-assessment Taxpayers will also retain the option to remain in self-assessment if they prefer.

The government has said that they will release further details in a transformation roadmap set to be published later this year.

Not every money-making hobby counts as a business for tax purposes. Knowing when a hobby crosses into trading territory is vital to avoid unexpected tax bills. If your side project is growing, it might be time to check your tax position and stay compliant.

For instance, HMRC manuals provide the example of someone who enjoys repairing cars or selling stamps in their spare time. Whilst this might lead to making what’s known as taxable supplies, that alone does not mean the person is operating a business. It all depends on whether the activity passes the "business test". This is a set of measures that HMRC uses to determine whether there’s a business intention.

Generally, small-scale or infrequent sales from hobbies aren’t considered a business. But in some cases, hobbies can evolve. What starts off as a hobby or side interest might grow over time into something more substantial, and that’s when it could begin to attract tax obligations. In fact, many well-known businesses have started out as hobbies before scaling into full operations.

When deciding whether a hobby has crossed into business territory, it’s also helpful to consider how income tax would apply. The Income Tax Act makes it clear that tax is charged on the profits of any trade, profession, or vocation and there are similar VAT rules.

It is also important to look at any costs that have been incurred and whether these might genuinely relate to a business activity.

MTD for Income Tax kicks off in April 2026 for those earning over £50k. Digital records, quarterly updates, and tougher penalties are on the way. If this affects you, it’s time to get ready.

Designed to modernise the tax system and improve accuracy, MTD will significantly change how Income Tax is reported and paid. With less than a year until the first group of taxpayers must comply, now is the time to prepare.

MTD for Income Tax will become mandatory for self-employed individuals and landlords with annual business or property income exceeding £50,000 from April 2026,. This will require taxpayers to submit quarterly updates to HMRC, maintain digital records, and comply with a new penalty regime for late submissions and payments.

The second phase of implementation will begin in April 2027, extending the requirements to those earning between £30,000 and £50,000. In a further expansion announced during the Spring Statement 2025, MTD obligations will apply to sole traders and landlords with income over £20,000 starting April 2028. The government has also indicated that it is considering the best approach for individuals earning below this threshold.

HMRC is currently contacting taxpayers whose 2023–24 self-assessment returns indicate income near or above the £50,000 threshold. These letters are intended to provide advance notice of upcoming obligations under MTD.
