New Tax Year, Clean Start: Switch MTD Software After Year-End Without Importing Old Records

Thinking about changing your MTD for Income Tax software? The best time is right after the tax year ends. HMRC says that if you switch after year-end, you do not need to import your digital records from previous tax years into the new product – you just need to store those earlier records securely and keep access to them. That makes the new tax year a perfect “clean start”.

Why year-end is the smart moment?

Under Making Tax Digital for Income Tax (MTD for ITSA), you keep digital records and submit via compatible software. When you change tools after the year closes, HMRC explicitly allows you to leave prior-year data where it is. Keep those records, but don’t feel obliged to shoehorn years of history into your new app. Your new year opens with fresh ledgers, cleaner categories, and simpler onboarding.

If you change during a live tax year, the rule is different: you must either import or recreate your current-year digital records in the new software (and, if you’re using bridging, link the new software to your spreadsheet). That’s doable – but more admin than waiting a few weeks for year-end.

“No need to import previous years”: what HMRC actually says

HMRC’s guidance, under “Changing your software”, states:

• “You do not need to import your digital records from previous tax years into the new software.”

• “You do need to store your digital records from previous tax years securely and be able to access them.”

That’s the whole opportunity: switch MTD software year end, start clean, no need to import previous years, and keep older data safely archived.

What to carry across (and what to leave alone)

Starting with a new tax year in the new app is a clean slate. You don’t need to move invoices, transactions, or categories from the old app. Simply set up the essentials: your business name, your accounting method (cash basis or traditional accounting), and how you want to report your periods (standard or calendar). After that, you’re ready to start recording and reporting for the new tax year. Keep last year’s invoices, receipts, and spreadsheets in your old system or archive, where you can produce them if needed. HMRC’s record-keeping page explains what a digital record must contain (amount, date, category) for each transaction going forward.

All-in-one MTD app at year-end: why it’s the simpler move

Switching right after the tax year ends gives you a clean cut: per HMRC, you don’t need to import digital records from previous years into your new software – just keep those earlier records stored and accessible. That means you can start the new year with a tidy setup instead of migrating history.

An all-in-one app is the easiest way to take advantage of that clean start. You’ll keep everything in one place – digital records, quarterly updates (7 Aug / 7 Nov / 7 Feb / 7 May), and the year-end submission – so there are fewer moving parts and less risk of errors. You get one source of truth for each business or property source, built-in prompts ahead of deadlines, consistent categories from day one, and smoother year-end adjustments because the whole workflow lives in a single system.

If you’re planning a change, set up your sources (each trade and any UK/overseas property), map your categories, connect your accounts, and start capturing transactions from day one of the new tax year. You’ll be aligned with HMRC’s digital-records rules and avoid the drag of wrestling old data into a new tool.
