Can My Accountant Do MTD for Me? The Honest Answer

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.

What MTD for Income Tax Actually Requires

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:

1. 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.
2. 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.
3. 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.

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.

What Happens If You Let Your Accountant Handle MTD but Miss Sending Them Records

If your accountant is submitting your quarterly updates on your behalf but you fail to get your records to them in time, the quarterly deadline is still missed, and the penalty falls on you, not them. HMRC's points-based system is unforgiving on this: each missed quarterly update earns you a penalty point, and once you accumulate enough points, a £200 fine is triggered. A sole trader who lets two consecutive quarters slip through the cracks is already more than halfway to that fine. You can see exactly how the points accumulate in our breakdown of how the MTD points system works.

The practical problem is timing. Accountants are managing dozens of MTD clients simultaneously, and they cannot submit a quarterly update without data from you. If you are running a busy trade and sending a shoebox of receipts every three months, your accountant has to do the categorisation and data entry themselves, which is bookkeeping work billed separately. The quarterly cadence under MTD is genuinely tighter than the old annual Self Assessment rhythm, and the communication overhead between you and your accountant increases accordingly.

The cleanest way to avoid this problem is to keep your own digital records throughout the quarter using MTD-compatible software, then share clean, categorised figures with your accountant before the deadline. That removes the data bottleneck, keeps your accountant's time focused on review and submission rather than data entry, and gives you a clearer picture of what you are actually paying for.

What to Ask Your Accountant Before April 2026

The honest answer to "can my accountant do MTD for me" depends heavily on which specific accountant you have and which software they plan to use. Not every practice is fully MTD-ready for income tax, and some are still working out their processes. Before assuming your current accountant will simply absorb the new obligations, ask them three direct questions: which MTD-compatible software they expect you to use for your records, whether their quoted fee already includes four quarterly submission filings per year, and whether they can accept data from whichever bookkeeping tool you are already using.

If their answers are vague, or if they expect you to email scanned invoices each quarter while they key in the figures, the responsibility for keeping compliant digital records still sits with you regardless of who presses the submit button. An accountant cannot make non-compliant source data compliant by handling it downstream. The software question is the tell: a practice that has not yet named a compatible solution for its sole trader clients is not yet ready to manage your MTD end to end.

One practical middle path worth discussing with your accountant is a clear division of labour: you handle digital record-keeping and quarterly updates yourself using dedicated software, and your accountant focuses on the end-of-period statement and final declaration, where their tax expertise genuinely earns its fee. That split typically keeps your annual accountancy bill much closer to what you pay today under Self Assessment, while ensuring you are compliant from the April 2026 start date.
