Switching MTD Software Mid-Year: Can You Do It?

You chose your MTD software, set it up, started recording transactions — and now you are not happy with it. Maybe it is too complex. Maybe it is too expensive. Maybe the interface frustrates you every time you use it. Whatever the reason, you are wondering: can I switch to different software in the middle of the tax year?

The short answer is yes. The longer answer explains why this is easier than most people think, and what you need to do to make the transition smooth.

Why People Worry About Switching

The fear of switching MTD software mid-year usually comes from three concerns:

  1. "Will I lose my submission history?" — No. Your submissions are stored by HMRC, not by your software.
  2. "Will HMRC know I switched?" — They will see submissions from a different software provider, but this is perfectly normal and not a compliance issue.
  3. "Will I have to re-enter everything?" — Possibly for the current quarter, but not for quarters already submitted.

Let's address each of these in detail.

Your Submission History Is Safe

Every quarterly update you submit through your MTD software is received and stored by HMRC. It sits in HMRC's systems, linked to your Unique Taxpayer Reference (UTR) and your MTD for Income Tax account. The data belongs to HMRC, not to your software provider.

If you switch from Software A to Software B, Software B can retrieve your MTD obligations from HMRC — including which quarterly updates have already been submitted. Your filing history is intact and continuous.

Think of it like switching email providers. Your previously sent emails are still in the recipients' inboxes, regardless of which email service you used to send them.

HMRC Does Not Mind

HMRC has no preference about which software you use, provided it is on their recognised list. Many taxpayers switch software, and HMRC's systems are designed to handle submissions from different providers across the same tax year.

There is no notification to HMRC when you switch — they simply receive your next quarterly update from a different software provider. This is routine and unremarkable from their perspective.

What You Need to Do

Step 1: Check What Has Already Been Submitted

Before switching, confirm which quarterly updates have been submitted to HMRC from your current software. Note the periods covered and the totals submitted. This is your reference point.

Most MTD software allows you to export your transaction data — usually as a CSV file. Download this before you leave your current provider. Even though HMRC has the summary data, having your detailed transaction records is valuable for your own purposes.

Step 3: Set Up Your New Software

Create your account with the new provider and complete the initial setup. This includes connecting to HMRC through the Government Gateway authorisation process. For a walkthrough of this, see our guide on how to connect MTD software to HMRC.

Step 4: Enter Current Quarter Transactions

If you are switching mid-quarter, you need to enter all transactions for the current quarter into your new software. This is the main effort involved in switching — and it is a one-time task.

For example, if you switch on 1 September (partway through Q2, which runs 6 July to 5 October), you need to enter all July and August transactions into your new software, then continue recording September and October transactions as normal.

Step 5: Submit Your Next Quarterly Update

When the quarterly deadline arrives, submit from your new software. The process is the same as with your previous tool — review the summary, confirm the figures, and submit.

Step 6: Revoke Access for Your Old Software (Optional)

If you want to tidy up, you can revoke your old software's HMRC authorisation through your Government Gateway account. This is not strictly necessary — the old software cannot submit anything without your involvement — but it is good housekeeping.

When Is the Best Time to Switch?

The smoothest time to switch is between quarters — after you have submitted one quarterly update and before you start recording transactions for the next quarter. This way, you do not need to re-enter any transactions.

For example: - Submit Q1 (6 April – 5 July) using your old software by the 7 August deadline - Set up your new software before Q2 starts - Record Q2 transactions (6 July – 5 October) entirely in your new software

However, switching mid-quarter is perfectly feasible — it just requires entering the current quarter's transactions into the new tool.

What About Year-End Declarations?

Your End of Period Statement and Final Declaration can be submitted from any HMRC-recognised software, regardless of which software you used for the quarterly updates. The year-end process pulls together the quarterly data held by HMRC, so it does not matter which software submitted each quarter.

If you switch software before the year-end declarations, your new software should be able to handle the EOPS and Final Declaration process using the data HMRC already holds.

Switching From Spreadsheets and Bridging Software

If you started with a spreadsheet-plus-bridging-software approach and want to move to dedicated MTD software, the process is the same. The bridging software submitted your quarterly data to HMRC, and that data is stored by HMRC. Your new dedicated software can pick up from where the bridging software left off.

The main advantage of switching from bridging software to a dedicated tool is simplicity — you replace two tools (spreadsheet + bridge) with one integrated solution.

Common Concerns Addressed

"My Accountant Set Up the Current Software"

If your accountant chose your current software and you want to switch, discuss it with them first. Some accountants prefer specific platforms because they use the practice version. However, the choice of MTD software is ultimately yours — accountants can work with any HMRC-recognised provider.

"I Have a Lot of Transactions to Re-Enter"

If switching mid-quarter means re-entering hundreds of transactions, consider waiting until the quarter boundary. Alternatively, check if your new software supports CSV import — many do, which means you can export from your old tool and import into the new one rather than entering each transaction manually.

"What If the New Software Does Not Work Either?"

Try before you commit. Most MTD software offers free trials. Use the trial period to enter some real transactions, explore the interface, and check that it meets your needs before cancelling your old provider.

"I Am Worried About Errors During the Transition"

The risk of errors is low if you follow the steps above. The most important thing is ensuring that your current quarter's transactions are complete and accurate in your new software before you submit. Double-check the totals against your bank statements.

Why People Switch

Understanding the common reasons for switching can help you evaluate whether a change is worthwhile:

  • Complexity — the software has too many features and is confusing to use
  • Cost — the monthly or annual price is higher than justified by what you use
  • Poor support — when you need help, it is not there
  • Reliability issues — submission failures, bugs, or downtime
  • Better option available — you discovered a tool that fits your needs more closely

If any of these ring true, switching is a rational decision. The effort of a one-time transition is a small price for software that works better for you every quarter going forward.

Frequently Asked Questions

Will switching software trigger an HMRC audit or inquiry?

No. Switching MTD software is routine and does not raise any flags with HMRC. They receive submissions from thousands of different software providers and have no interest in which one you use.

Can I switch software multiple times in the same year?

Yes, though it is not recommended simply due to the hassle of re-entering transactions each time. If your first switch does not work out, you can switch again — but take advantage of free trials to find the right tool before committing.

Do I need to tell HMRC that I am switching software?

No. There is no requirement to notify HMRC when you change MTD software providers. They simply receive your next submission from the new provider's API connection.

What if my old software provider shuts down?

Your submission history is held by HMRC, so a provider shutting down does not affect your compliance record. You would need to set up with a new provider and continue from wherever you left off.

Can I switch from paid software to HMRC's free tool?

Yes. You can switch to HMRC's free MTD tool at any time, with the same considerations as switching to any other provider. Keep in mind the limitations of the free tool, which we cover in our article on free MTD software from HMRC.
