MTD for Income Tax from April 2027: the £30,000 threshold explained

 

If you are a sole trader or a landlord, a quiet revolution in how you report income to HMRC is less than a year away. From 6 April 2027, Making Tax Digital (MTD) for Income Tax becomes mandatory for self-employed individuals and landlords with qualifying income over £30,000. A further wave follows in April 2028, when the threshold drops to £20,000.

HMRC estimates around 1.07 million more businesses will be pulled into digital reporting as a result of this expansion. That is not a niche compliance change. It is one of the biggest shifts in UK personal tax administration in a generation.

Here is what the rules mean in practice, and what you should be doing about them right now.

What MTD for Income Tax actually requires

Under the current system, sole traders and landlords file one Self Assessment return a year, usually months after the tax year ends. MTD replaces that single annual exercise with digital record-keeping and regular reporting.

The core requirements are straightforward:

Keep digital records. From the relevant start date, you must record your business income and expenses in functional compatible software. That means MTD-compatible software or an app that talks to HMRC's systems, or a spreadsheet paired with bridging software. Paper ledgers and manual spreadsheets on their own no longer count.

Submit quarterly updates. Instead of one annual return, you send HMRC a summary of your income and expenses every quarter. These are not tax payments and they are not full returns, they are progress reports that give you a rolling estimate of your tax liability during the year.

File a final declaration. At year end, you confirm your final position with a final declaration that replaces the traditional Self Assessment return. This is where you add anything not captured in the quarterly updates, such as employment income or capital gains, and claim your reliefs.

Who is affected and when

From 6 April 2027: sole traders and landlords with qualifying income above £30,000 a year. Qualifying income means your total gross income from self-employment and property before expenses, not your profit. This trips up a lot of people: a landlord with £32,000 of rental income but only £10,000 of profit is still in scope.

From April 2028: the threshold drops to £20,000, catching hundreds of thousands more small operators.

Partnerships and companies are not in this wave. Limited companies remain outside MTD for Income Tax for now, with MTD for Corporation Tax expected at a later, still-unspecified date.

If your income sits anywhere near £20,000 to £30,000, plan as though you are in scope. Income fluctuates, and a good year can push you over the line unexpectedly.

What "digital records" means in practice

This is the part that worries most small businesses, and it is worth demystifying. Digital record-keeping does not mean expensive enterprise software. The market is full of affordable MTD-compatible options aimed at sole traders and landlords, many costing a few pounds a month.

In practice it means every invoice, receipt, and expense is captured digitally at or near the time it happens, bank feeds connect your business account so transactions flow in automatically, and the software prepares each quarterly update with a couple of clicks for you or your accountant to review before submission.

The real discipline shift is timing. The days of stuffing a year's receipts into a carrier bag for your accountant in January are over. Quarterly reporting only works if the underlying records are genuinely kept during the quarter.

What to do now

April 2027 sounds distant. It is not. Tax years, software contracts, and new habits all need lead time. Here is a practical checklist:

1. Work out whether you are in scope. Add up your gross self-employment and property income for the last complete tax year. Over £30,000 means the first wave. Between £20,000 and £30,000 means the second.

2. Choose your software early. Do not wait until March 2027. Pick MTD-compatible software this tax year, so you can run your books digitally through 2026-27 and iron out problems before the deadlines are real.

3. Separate your finances. If you still run business and personal spending through one account, fix that now. Clean bank feeds are the engine of effortless digital records.

4. Talk to your accountant about quarterly workflow. MTD changes the accountant-client rhythm from annual to quarterly. Agree on who prepares the updates, who reviews them, and what each quarter will cost. If you manage the books yourself, consider getting self-assessment and tax compliance support so the quarterly cycle does not eat your working week. Honest quarterly numbers are a gift disguised as compliance: owners who see their profit position four times a year make better decisions than those who discover it fourteen months later.

The bottom line

HMRC has legislated the dates, and the software ecosystem is ready. The businesses that treat 2026-27 as a practice year will sail into April 2027.
