Making Tax Digital (MTD) for Income Tax is now just days away. It begins on the 6th of April. I would be willing to bet that a significant number of people reading this either do not fully understand what that means or have assumed it does not apply to them.
If you are a sole trader or a landlord, and your gross income—not your profit—was over £50,000 on your last tax return, this applies to you from the 6th of April. That means it is happening right now.
HMRC has been sending out letters in batches. You might have received one, but many have not. Not receiving a letter does not mean you are exempt; it simply means HMRC has not written to you yet. You are still legally required to register.
The clock is ticking to ensure you are compliant. This is genuinely the biggest structural change to income tax reporting in over 30 years, and the level of awareness is nowhere near where it should be.
What Making Tax Digital Actually Means for You
Up until now, the deal for sole traders and landlords has been straightforward. You do your thing throughout the year and keep your records however you choose—in software, on a spreadsheet, or even in a shoebox. Once a year, usually in January, you or your accountant pulls it all together and submits one Self Assessment tax return.
That system is being replaced.
If you are in the first wave, you are now required to keep digital records of your income and expenses throughout the year using HMRC-approved software. Instead of one annual return, you must submit quarterly updates to HMRC every three months, summarizing your income and outgoings.
On top of that, you still need to file a final year-end declaration by the 31st of January. You are going from one submission to five submissions a year.
If you have income from both self-employment and property—for example, you are a sole trader who also lets out a flat—you need to file separately for each income stream every quarter. That is eight quarterly submissions plus your final year-end declaration.
HMRC will tell you that these quarterly updates are not tax returns, and technically, they are right. They are summaries. They are not calculating your tax liability each quarter. But the point is, you need to have your numbers perfectly in order every three months, digitally recorded in software that talks directly to HMRC systems. That is a fundamentally different way of working.
Key Takeaway
MTD transforms tax reporting from an annual administrative task into a continuous, quarterly compliance requirement. If your gross income exceeds £50,000, you must move away from spreadsheets and shoeboxes immediately and adopt HMRC-compatible digital record keeping.
Does Making Tax Digital Apply to Me?
HMRC is rolling this out in phases based on your qualifying income. This is critical: qualifying income means your gross income, not your profit. It is the total amount coming in before you deduct any expenses.
- Phase One (6th April 2026): Applies to anyone with qualifying income over £50,000 based on their 2024/25 tax return. Around 864,000 people fall into this bracket.
- Phase Two (April 2027): The threshold drops to £30,000.
- Phase Three (April 2028): The threshold drops again to £20,000, bringing an estimated three million taxpayers into the regime.
A crucial detail that many miss is that the threshold is based on combined gross income from self-employment and property. If you invoice £38,000 a year as a sole trader and receive £15,000 from a rental property, your qualifying income is £53,000. You are in scope from April 2026.
Once you are in the scheme, you stay in it. Even if your income drops below the threshold the following year, you remain in MTD until your income has been below the relevant threshold for three consecutive years.
Note: If you are a limited company director, this does not apply to your company. MTD for Corporation Tax is a separate consultation with no current introduction plan. However, if you are a director who also has self-employed side income that breaches the thresholds, that specific personal income will be caught.
The Real Cost of MTD Compliance
This is where the reality of the new system hits.
The first cost is software. You need HMRC-compatible software to keep digital records and file updates. While there are some basic free tools, if your affairs are anything beyond incredibly straightforward, you need a paid subscription to software like Xero or QuickBooks. This could cost between £30 and £60 a month, or up to £360 a year just for the software.
The second cost is professional fees. Because the workload has increased from one annual submission to five minimum submissions, accountancy fees will naturally rise to cover the additional bookkeeping and reporting requirements. Estimates suggest an average additional cost of around £480 per person caught in this first wave.
The New Penalty Points System
What is highly concerning is the new penalty structure HMRC is introducing. It is a points-based system.
Every time you miss a quarterly deadline, you receive a penalty point. If you accumulate four points, you are hit with a £200 fine. Every missed deadline after that incurs another £200 fine.
These points do not just disappear. They are only reset after 12 months of consecutive, on-time submissions, provided everything due in the previous 24 months has been received. You essentially need a two-year clean sheet to clear your record.
There is a soft landing for the first year. If you are in the April 2026 wave, you will not receive penalty points for late quarterly updates during that first window. However, the soft landing does not apply to your year-end tax return. If you file your 2026/27 return late, the penalty points apply in full. Furthermore, the soft landing does not apply to anyone joining in the second wave in 2027/28.
Late payment penalties are separate. You now have just 15 days to pay before the penalty kicks in, down from 30 days under the current system. The penalties then escalate the longer you leave it, plus interest applies from day one.
What You Need to Do Right Now
Nobody wakes up thrilled about quarterly tax submissions, but this is a scenario where being two months late costs you significantly more than being two weeks early. Here is what you need to do practically before the 6th of April:
- Check your qualifying income: Review your 2024/25 tax return. Look at your gross income from self-employment and property. If the combined figure is above £50,000, you are in the first wave. It is not optional.
- Register for MTD: HMRC will not do this automatically. You need to sign up through the gov.uk MTD service using your Government Gateway credentials.
- Choose your software: If you use Xero or QuickBooks, ensure it is MTD-compatible for Income Tax, not just VAT. If you do not use software, implement it immediately so you are ready for the first quarterly update due in July.
- Speak to your accountant: If you have an accountant, confirm their plan for MTD. If you do not have one and feel overwhelmed, now is the time to secure specialist help.
The compliance burden is not getting lighter. Thresholds are dropping, penalties are increasing, and HMRC’s systems are getting better at catching gaps. Get ahead of it now.
