Transitioning to Making Tax Digital (MTD) for Income Tax – This April

Transitioning to Making Tax Digital (MTD) for Income Tax This April

IMPORTANT: Making Tax Digital (MTD) for Income Tax officially takes effect from the beginning of April 2026. If you are self-employed, a sole trader, or receive income from property, it’s likely that this will affect you. Today’s guide outlines key dates, the changes, who they affect, how complying with MTD will impact your business — and how Taxfile can help new and existing clients transition quickly and easily.

What’s This About?

(Transitioning to MTD for Income Tax)

Today’s guide is about the need for many people in the UK to transition to Making Tax Digital (MTD) for Income Tax, the new and regular way of reporting income digitally to HMRC. For those affected, it replaces the traditional once-a-year tax return with 5 smaller submissions spread out through the year.

Who Does MTD for Income Tax Apply To?

MTD applies to those earning a qualifying income above a certain threshold from self-employment, property, or a combination of the two.

What is the Threshold for Participation?

Those with a qualifying income over £50k will be affected first. However, that £50k threshold for obligatory entry will reduce quite quickly, meaning people with much lower incomes will also soon be affected. Those earning a qualifying annual income as low as £20k will therefore also need to comply with MTD fairly imminently.

When Do People Need to Start Complying?

For those with a qualifying annual income over £50k in the financial year 2024-25, it’s time to get on board with MTD for Income Tax right away — MTD digital record-keeping is required from early April 2026. For them, their first quarter’s digital submission to HMRC is then required no later than 7 August.

Others with lower incomes will soon follow suit, with those receiving qualifying annual incomes over £30k starting in April 2027, and those over £20k in April 2028. It’s anticipated that those in partnerships will also soon need to comply (date TBA).

While this represents a change in how tax information is reported, Taxfile’s goal is to ensure the transition is as easy as possible. We want you to feel free to continue delivering your services to customers as usual, while we handle all the MTD ‘heavy lifting’ for you.

Connect With Us to Get Started

with MTD for Income Tax

Taxfile’s tax agents are currently reaching out to new and existing clients to assist with this transition. Existing clients should expect to hear from their dedicated agent by the 25th of March 2026. If your annual turnover is above £50,000 and you have not heard from your Taxfile agent by that date, or are a new customer looking to begin your MTD journey, please contact us immediately so we can ensure you remain compliant.

(or contact your dedicated tax agent directly if you are an existing client).

What Do You Need to Do?

To keep your records compliant and up to date, we require your financial data in a digital format:

  • Bank Statements: Please provide these as CSV or Excel digital downloads.
  • Cash Transactions: If you handle cash, please provide receipts or a clear digital record.
  • Business Bank Accounts: We strongly recommend using an account purely for business. Having little to no personal transactions therein will make tracking business income and expenditure much easier.

Personal Support & Reassurance from Taxfile

We understand that not everyone is comfortable with new technology. If you do not have a laptop, a home computer, or a banking app that provides downloads, please do not worry. You are more than welcome to sit with us each quarter to go through your records in person.

Ultimately, we will provide HMRC with the necessary transaction list that reflects your taxable earnings and relevant costs. We view this as a simplification; by filing on a real-time basis throughout the year, we all avoid the stress of a single year-end deadline.

Taxfile Fees

Taxfile will not be charging extra fees for this service. We will simply divide our usual annual self-assessment tax return fee into four equal instalments to help manage your cash flow.

Quarterly Deadlines

Please note the following periods and the deadlines by which you must submit your data to HMRC:

Accounting Period*HMRC Submission Deadline
6 Apr – 5 Jul OR 1 Apr – 30 Jun*7 August
6 Jul – 5 Oct OR 1 Jul – 30 Sep*7 November
6 Oct – 5 Jan OR 1 Oct – 31 Dec*7 February
6 Jan – 5 Apr OR 1 Jan – 31 Mar*7 May

* (Your business accounts may be based on dates either from full calendar months e.g. starting from 1 April, or months based on the Financial Year, which starts on 6 April).

We very much look forward to hearing from — and seeing — our customers more regularly. The Taxfile team is here to support you every step of the way.

Late with your tax return and tax payment? What happens now?

Missed the Tax Return Deadline? What Happens Now?

/in , , , , , , , , , , , , , , , , , , , , , , , , /by

Missed the Tax Return Deadline? What Happens Now?

[Updated 1 February 2026]: If you missed the 31 January deadline to submit your self-assessment tax return, you are now into the penalty stage. HMRC applies an automatic £100 penalty to those who are anywhere from 1 day to 3 months late. Further penalties are then added if you take even longer to comply. It’s even worse if you haven’t paid the tax owed to HMRC by 31 January because you’ll then owe interest on that too.

Our Advice if You’re Late

If you are late submitting your tax return and/or paying the tax owed, our advice is to:

  1. submit your tax return without delay;
  2. pay as much tax as you can as soon as possible*.
    By doing both, you’ll minimise the penalty and interest payable to HMRC.

* Payment of any historic tax for 2024/25 and prior years is best dealt with by the last day of February at the latest. Any amount that remains due for 2024/25 is considered late thereafter and will attract an automatic HMRC charge of 5%.

What if you Cannot Pay?

If you cannot pay, or have tax arrears, it’s important that you demonstrate to HMRC that you’re paying as much as you can — and as regularly as possible. The good news is that HMRC has a quick and easy facility for exactly this purpose. By calling 0300 200 3402, you can pay using a debit card. It takes only minutes and doesn’t require any explanation — give it a try!

You will need your tax reference and, after making a payment, will be given a payment reference.

Possible Excuses for Late Tax Returns

What are your options if there were genuine reasons, beyond your control, that stopped you being able to submit your tax return on time? Well, if you “took reasonable care to meet” a deadline and there was a genuine reason why you were late, you have the option to appeal. However, your circumstances must fit HMRC’s eligibility criteria. Let’s take a look at those below.

Circumstances that are taken into account by HMRC when considering appeals include:

  • if a close relative or partner died shortly before the tax return or payment deadline;
  • if you had to stay in hospital unexpectedly;
  • if you had a life-threatening or serious illness;
  • if your computer or software failed at the time you were preparing your online return;
  • if HMRC’s online services were disrupted;
  • if you were prevented from filing your return or paying your tax because of a fire, flood or theft;
  • if there were unexpected postal delays;
  • if you have a disability of mental illness that affected the delay;
  • if you misunderstood your legal obligation, or were unaware of it;
  • if someone you’d appointed for the task (e.g. accountant or tax adviser) failed in their obligation on your behalf;
  • and occasionally other reasons which, if genuine, HMRC may deem to be relevant (for example, some Covid-related circumstances).

Excuses that aren’t usually accepted by HMRC include:

  • you didn’t receive a reminder from HMRC;
  • you found HMRC’s online system too difficult to use;
  • your cheque bounced or payment failed due to you having insufficient funds;
  • you made an error on your return.

Appealing Against an HMRC Penalty

You have the right to appeal against HMRC’s decision to issue you a penalty so long as it’s appealed soon enough after the penalty notice. That includes penalties for late tax returns or payments. Taxfile can help advise you about all of that (see below).
