Preparing for the £30,000 MTD threshold from April 2027

The next mandatory MTD Income Tax phase begins on 6 April 2027 for eligible individuals with qualifying income above £30,000 in 2025/26, subject to exemptions. Preparation starts with the right income figure and records, not with the amount of profit left in the bank.

Check the phased entry tests

Qualifying income generally combines relevant gross self-employment and property income before expenses. Employment pay and other personal income are not simply added to this particular test. HMRC explains qualifying income.

Prepare the workflow before the start date

List the income sources, accounts and records needed. Check exemptions and circumstances affecting the requirement. Choose software that supports the actual business and annual-return needs, and agree the role of any adviser.

Try regular digital record-keeping before mandatory reporting begins. This can reveal missing provider statements or mixed-account problems. Starting bookkeeping earlier does not automatically mean you must make voluntary MTD submissions; establish that separately.

Worked example: trade and property together

An individual has £24,000 qualifying trade income and £9,000 qualifying property income in 2025/26. The combined £33,000 exceeds the £30,000 threshold, even if each activity is below it and expenses leave a much smaller profit.

Subject to the full conditions and exemptions, the April 2027 phase may apply. Looking only at one activity or taxable profit would miss the combined-income test.

Choose software by the work it needs to do

Start with your actual income sources and records. A sole trade, a UK property business and foreign property can involve different requirements. A product suitable for one set of circumstances is not automatically suitable for every annual-return item you might have.

HMRC's software guidance allows different approaches, including software connected to existing spreadsheets. Check the complete workflow: importing or recording transactions, reviewing the quarterly summary, submitting it, making corrections and completing the annual return.

Try a representative sample that includes a refund, a private transaction, a cash item and an awkward bank description. Ask how the system handles a missing period and how you export records if you leave. These questions are more informative than a long feature list.

Software support and professional tax advice are different services. Confirm who answers each kind of question, when help is available and what the quoted fee covers. Avona.app's entry-level self-service price is £15/month; professional services and additional product capabilities should be checked against the current scope rather than assumed to be included.

Keep the evidence connected to the figures

Your digital record should explain the amount, date and nature of the transaction. Keep the invoice, receipt, statement or other evidence that supports it. A photograph can make a paper document easier to retain, but a folder of photographs alone does not create complete transaction records.

For sole traders, HMRC normally requires business records to be kept for at least five years after the relevant 31 January filing deadline. Keep them longer where the rules for a late return, enquiry or other circumstances require it. Check the record-retention guidance.

Make the records usable by your future self. Include a short explanation where a bank description is vague, retain the calculation behind a business-use split and make corrections traceable. For a missing receipt, try the supplier account, email confirmation or a replacement invoice before relying on incomplete evidence.

At review time, compare your records with the bank or payment account and investigate differences. Equal totals are useful, but two errors can cancel each other out. A sample of individual transactions can reveal a duplicated purchase or an omitted customer receipt that a totals-only check misses.

A review that checks more than the total

Start with coverage: the correct person, business and period, plus all relevant accounts and cash records. Then look at completeness. A feed can be connected today while still missing an earlier week. Confirm the earliest and latest transactions against the source.

Next, inspect unusual items. Large transfers, loan receipts, refunds, net settlements and private purchases often need more context than a bank description provides. Check for duplicate imports where a statement overlaps a live feed. An automatic warning is useful evidence to investigate, not proof that the entry must be removed.

Finally, review category totals. A category unexpectedly showing zero, a large increase or a negative amount deserves an explanation. You do not have to make every annual tax adjustment at this stage, but you should understand the records behind the summary you approve.

HMRC explains what quarterly updates contain. Keep the approved version and the resulting acknowledgement together. If something later changes, correct the source record and use the software's supported update process so you can explain which figures are current.

Use the time available realistically

Check the actual date and count the months remaining to April 2027. A September 2026 reader has less than a year, so an old promise of twelve months' preparation is misleading. Establish the routine, test exports and resolve support needs before the first mandatory period begins.

Take the next step

Avona.app offers a self-service route from £15/month. Bring your records together, review the figures and choose a workflow that fits your business. For professional help, discuss the scope and total price of Avona Concierge, managed by chartered accountants, before choosing a service.
