A tax return once a year may have suited the way you worked. From April 2026, some sole traders will need a more regular routine. Good MTD ITSA support for sole traders is not about making tax more complicated. It is about setting up a simple system that keeps your income and expenses organised as you go, so deadlines do not become a last-minute worry.
If you run a business in Worthing or elsewhere in West Sussex, the practical question is likely to be: “Does this apply to me, and what do I actually need to do?” The answer depends on your income, the type of records you keep and whether your software is ready. Starting early gives you time to make sensible choices without disrupting the day-to-day running of your business.
What MTD ITSA means for sole traders
Making Tax Digital for Income Tax Self Assessment, usually shortened to MTD ITSA, changes how certain people report self-employment and property income to HMRC. Rather than relying on a spreadsheet, paper records or a pile of receipts at the end of the tax year, you will need to keep digital records and send updates using compatible software.
This does not mean you will pay tax four times a year. Your usual Income Tax payment dates remain in place. What changes is the way information is recorded and sent to HMRC during the year.
For a sole trader, the main requirements are to keep digital records of business income and expenses, send quarterly updates through compatible software, and complete a final declaration after the end of the tax year. The final declaration confirms your overall tax position, including any other income that needs to be reported.
The goal is to give you a clearer, more up-to-date view of your figures. That can be genuinely useful, but only when the records going in are accurate. Software cannot fix missing invoices, personal spending mixed with business costs or transactions that have never been explained.
Who needs to join and when?
The first compulsory group joins MTD ITSA from 6 April 2026. This applies to sole traders and landlords with qualifying income above £50,000 in the 2024-25 tax year.
Qualifying income means your gross income from self-employment and property before expenses are deducted. If you have both business and rental income, the figures are added together to assess whether you meet the threshold. For example, a sole trader with £42,000 of sales and £12,000 of rental income would have qualifying income of £54,000.
The threshold reduces over the following years. People with qualifying income above £30,000 are due to join from April 2027, while those above £20,000 are due to join from April 2028. If your income is below the relevant threshold, you are not required to join yet, although you may be able to use the system voluntarily if it suits your business.
Some people may be exempt, for example where it is not practical for them to use digital tools. Exemptions are not automatic, so it is worth getting advice before assuming that they apply. General partnerships are not currently within the mandatory timetable, but individual sole traders should not assume this excludes them simply because they work alongside others on projects.
MTD ITSA support for sole traders starts with tidy records
The easiest way to prepare is to improve the information you already have. A regular bookkeeping routine is much less stressful than trying to reconstruct a year of trading after the event.
Your records should show the date, amount and category of income and expenses. You will also need to retain evidence such as sales invoices, purchase receipts and bank transactions. A separate business bank account is not compulsory for every sole trader, but it makes bookkeeping far clearer. It reduces the chance of personal purchases being included as business costs and makes it easier to see what the business is really earning.
Compatible software is central to MTD ITSA. This could be cloud accounting software, or another approved digital solution that records transactions and sends the required updates to HMRC. The best option depends on how you trade. A consultant sending a handful of invoices each month may need a different setup from a tradesperson handling materials, mileage, subcontractors and CIS deductions.
There is a trade-off here. The cheapest software is not always the most suitable if it creates extra admin or leaves you unsure how to categorise transactions. Equally, a feature-heavy system can be unnecessary if your business is straightforward. The right choice is one you can use consistently, with support available when something does not look right.
What the quarterly updates involve
Under MTD ITSA, you will send a summary of your business income and expenses for each quarterly period. These updates are not final tax returns. You can correct or adjust figures later if needed, and your year-end process remains important.
The standard quarterly periods run from 6 April to 5 July, 6 July to 5 October, 6 October to 5 January and 6 January to 5 April. A calendar quarter election may be available for some businesses, allowing records to be aligned to more familiar dates such as 30 June and 30 September. This can make regular bookkeeping easier, particularly if you already review your figures monthly.
After each period, the update is normally due by the 7th of the following month. The final declaration is due by 31 January after the end of the tax year, as it is under the current Self Assessment system.
Quarterly reporting sounds demanding when you first hear about it. In practice, it is far more manageable when transactions are reconciled regularly. If you review your bank feed, upload receipts and raise invoices as part of your normal routine, the quarterly submission becomes a check-in rather than a scramble.
A practical way to get ready
Preparation does not need to happen all at once. Start by looking at the most recent tax return and checking your qualifying income. If you are near a threshold, plan as though you may be required to join soon, especially if your business is growing.
Then focus on four areas:
- Bring your bookkeeping up to date, including any outstanding bank reconciliations and uncategorised transactions.
- Keep business and personal spending separate wherever possible.
- Choose compatible software that suits how you invoice, pay suppliers and manage expenses.
- Set aside a regular time each week or month to review your records and ask questions early.
It also helps to think beyond compliance. Accurate, current figures can show whether a client is paying late, whether costs are rising or whether you have enough cash for a quieter month. MTD ITSA can be a useful prompt to build better financial habits, rather than simply another HMRC task.
Where hands-on support can help
Many sole traders are perfectly capable of using software, but do not have the time to check every transaction, understand expense categories or deal with problems before a deadline. That is where personal support makes a real difference.
A bookkeeper can help set up your software properly, create a straightforward process for receipts and invoices, reconcile your bank transactions and review the information before updates are submitted. You remain close to your business finances, without carrying the full burden of the admin alone.
Support is particularly valuable if your income varies, you have rental income alongside your trade, use CIS, are registered for VAT or have fallen behind with your books. These situations do not make MTD ITSA impossible, but they do make a one-size-fits-all approach less helpful. Calm, clear advice can prevent small recording errors becoming a larger tax problem later.
Angel Bookkeeping & Payroll Services can provide practical, tailored help with digital bookkeeping and MTD ITSA preparation, explaining what is needed in plain English and keeping the process manageable.
Give yourself time, not pressure
The best time to prepare for MTD ITSA is before a filing deadline is close. A few small changes now – cleaner records, suitable software and a regular bookkeeping routine – can remove much of the uncertainty.
You do not need to become an accounting expert to stay compliant. You just need a clear process, reliable records and someone to turn to when you need straightforward advice you can trust.
