Can My Accountant Do MTD for Me? The Honest Answer
Your accountant can help with MTD, but not in the way you might hope. Here's what they can and cannot do, and what it will cost you.
Your accountant has handled your Self Assessment for years. So surely they can just "do MTD" for you when it kicks in from April 2026? The honest answer is: partly, but probably not in the way you are imagining, and almost certainly not for free.
This is one of the most searched questions among sole traders right now, and the answers floating around are either too vague to be useful or quietly written by accountancy firms with a financial interest in your confusion. Let us cut through both.
- Your accountant can file your MTD quarterly updates and end-of-period statements on your behalf, but you still need compliant software to generate the digital records first.
- The day-to-day record-keeping burden under MTD falls on you, not your accountant, unless you pay them to do that too.
- Accountants are already raising their fees for MTD clients. One survey found 56% of UK accountants planned to increase charges once MTD launches.
- A dedicated MTD app like TapTax can handle the quarterly submissions directly, reducing what you need to pay an accountant for.
- Delegating everything to an accountant is legal and possible, but it is the most expensive route. Understanding what you actually need help with saves money.
What MTD for Income Tax Actually Requires
- MTD for Income Tax Self Assessment (MTD ITSA)
- HMRC's programme requiring sole traders and landlords with income above £50,000 (from April 2026) and £30,000 (from April 2027) to keep digital records and submit quarterly updates to HMRC via approved software, replacing the single annual Self Assessment return.
Before you can answer the question of what your accountant can do, you need to understand what MTD actually demands. There are three distinct obligations:
- Digital record-keeping. Every income and expense transaction must be recorded digitally, in software that connects to HMRC's systems. A spreadsheet on its own does not qualify unless it is linked to bridging software.
- Quarterly updates. Four times a year, a summary of your income and expenses must be submitted to HMRC via that approved software. The deadlines fall on 7 August, 7 November, 7 February, and 7 May.
- End-of-period statement and final declaration. Once a year, you confirm the figures, add any adjustments, and declare your final tax position. This replaces the old Self Assessment return.
All three steps require approved software. None of them can be done via HMRC's own free online portal because HMRC has not built one. That decision alone has created a software industry worth hundreds of millions of pounds in recurring subscription revenue. But that is a separate story.
The key point: your accountant can interact with steps two and three on your behalf, using an agent login. What they cannot do is magic away step one.
What Your Accountant Can Legally Do Under MTD
Accountants can act as your "agent" under MTD, just as they currently act as your agent for Self Assessment. This means they can:
- Submit your quarterly updates to HMRC on your behalf
- File your end-of-period statement
- Complete your final declaration
- Correspond with HMRC if something goes wrong
- Review your records before submission to catch errors
If your accountant uses practice management software such as Xero Practice Manager, QuickBooks Accountant, or Iris, they may be able to pull your data through and submit directly from their system. You would typically need to use a compatible bookkeeping tool that feeds into their system, or send them your records in a format they can import.
So yes, your accountant can press the submit button four times a year instead of you. The question is whether that is worth the extra cost, and what you still have to do regardless.
What Your Accountant Cannot Do For You
This is the part that surprises most sole traders. Your accountant cannot:
- Record your transactions for you unless you send them receipts, invoices, and bank statements regularly throughout the year (which is bookkeeping, and it costs extra)
- Use non-compliant software on your behalf (a Word document or paper ledger still fails the digital records requirement even if your accountant then types it into their system)
- File quarterly updates without data, which means if you have not tracked anything for three months, there is nothing to submit
- Exempt you from needing MTD-compatible software in your own business
The practical implication: even if you delegate every submission to your accountant, you still need a system for capturing your own income and expenses in a digital format throughout the year. That is the bit that changes your daily working life, and no amount of accountant delegation changes it.
The Real Cost of "Just Let My Accountant Do It"
Let us use a concrete example. Dave is a self-employed electrician turning over £62,000 a year. He currently pays his accountant £450 a year to file his Self Assessment return. Under MTD, his accountant now needs to:
- Review and submit four quarterly updates
- File an end-of-period statement
- Complete the final declaration
- Potentially troubleshoot any HMRC queries
That is roughly five to six times more touchpoints than before. Most accountancy firms are already signalling fee increases of between £200 and £600 per year for sole trader MTD clients, according to research published by the Institute of Chartered Accountants in England and Wales (ICAEW). For Dave, his £450 annual bill could easily become £800 to £1,050.
And that is before the bookkeeping cost. If Dave wants his accountant to actually do the record-keeping too, he is looking at monthly bookkeeping fees on top, typically £80 to £150 per month for a sole trader at his turnover level. That is an additional £960 to £1,800 a year.
The full "accountant does everything" package could cost Dave between £1,800 and £2,800 annually. For a tradesperson who was previously paying £450 a year, that is a significant change.
A Smarter Split: What to Handle Yourself
The most cost-effective approach for most sole traders is not "do everything yourself" or "pay your accountant for everything". It is a deliberate split.
Handle yourself:
- Day-to-day digital record-keeping using an MTD-compatible app
- Quarterly updates submitted directly through that app
Keep your accountant for:
- Year-end review and final declaration
- Tax planning advice
- Any HMRC correspondence or disputes
This approach keeps your accountant focused on the high-value work that genuinely benefits from their expertise, while the routine quarterly submissions are handled by software. A dedicated MTD app typically costs £10 to £20 per month. Compare that to paying your accountant to submit four updates a year, and the maths generally favours the app.
Tools like TapTax are built specifically for this model: sole traders handle their own digital records and quarterly submissions without needing accounting qualifications, while still having the option to share access with an accountant for the year-end work.

How to Have a Productive Conversation With Your Accountant
If you currently have an accountant, the worst thing you can do is assume MTD is sorted because they exist. Ask them these specific questions:
1. What software do you want me to use? Your accountant may have a preferred platform, such as Xero or QuickBooks, that integrates directly with their practice software. Using something incompatible creates extra work and extra charges.
2. What will your MTD fees be from April 2026? Get this in writing before the mandate arrives. Some firms have already published revised fee schedules; others have not. You deserve clarity.
3. Will you submit my quarterly updates, or do you expect me to? Do not assume. Some accountants plan to take on full agent responsibility for submissions; others expect the client to use their own app and share read-only access.
4. What do you need from me, and when? If your accountant is doing the record-keeping, establish a clear workflow now. Monthly receipt drops? A shared Dropbox? A bookkeeping app they can access? Leaving this undefined leads to the classic last-minute scramble, except now it happens four times a year instead of once.
What About Agents Filing on Your Behalf: Is There a Legal Snag?
There is one nuance worth flagging. Under the current MTD rules, the quarterly update must be submitted from software that holds the digital records for that period. This means the software has to have actually been used to record transactions, not just used to submit a number your accountant typed in from a paper receipt bag.
HMRC's guidance makes clear that the digital link must be maintained throughout. If you hand your accountant a carrier bag of receipts in January and they create digital records retrospectively, that technically does not satisfy the "digital records kept throughout the period" requirement. HMRC has indicated some pragmatism in early years, but relying on that is not a compliance strategy.
The practical answer: you need a digital record-keeping habit, not just a digital submission habit. These are different things, and only the first one changes how you work day to day.
For a deeper look at what HMRC actually means by digital records and where tradespeople typically go wrong, the post on Digital Records HMRC Demands: What Tradespeople Get Wrong is directly relevant.
What Happens If You Miss a Quarterly Update?
Whether you file it yourself or your accountant files it for you, a missed quarterly update means a penalty point. Under the new points-based system, four points triggers a £200 fine, with further penalties accumulating from there. If your accountant misses a deadline because you did not send them your records in time, the penalty lands on you, not them.
This is worth understanding clearly. The legal obligation is yours. Your accountant acts as your agent, not as a guarantor. If the deadline is 7 November and you send your accountant a box of receipts on 9 November, the submission is already late. The MTD Late Payment Penalty: How the Points System Works post explains exactly how the escalation works if you are not yet clear on the numbers.

The Bottom Line
Can your accountant do MTD for you? Yes, for the submissions. No, for the record-keeping, unless you are willing to pay bookkeeping fees on top. And not for free, regardless.
The question you started with, whether you can simply hand this off and forget about it, is the wrong frame. MTD changes how you run your business throughout the year, not just at year-end. The sole traders who will handle it most painlessly are the ones who accept that early and choose the right tool for the day-to-day work, rather than hoping their accountant absorbs the entire problem.
If your income is above £50,000 and you are counting down to April 2026, the most useful thing you can do today is ask your accountant the four questions listed above, and get their answers in writing before fee season arrives.
