Starting April 2026, Making Tax Digital (MTD) for Income Tax will significantly impact self-employed businesses and landlords.
Your MTD start date depends on your total combined turnover (trading turnover + rental receipts (if any) per this table.

The new rules essentially mandate digital record-keeping so that all businesses can send quarterly updates to HMRC.
If you're a sole-trader, partnership or landlord keeping paper-only or spreadsheet records, then - to put it simply - you'll need to switch to digital (online cloud) bookkeeping.

Making Tax Digital (MTD) for Income Tax - The Details
The following is what we know so far per HMRC's Guidance.
MTD for VAT-registered businesses was first introduced in April 2019 (if you're VAT registered, you'll already be using compliant software, but you may be required to make additional electronic reports to HMRC)
Turnover test - MTD applies to businesses with a turnover above £30,000, including income from all businesses and property. So, a person with £15,100 of trading income and £15,000 of rental income will be required to report under MTD as their total turnover exceeds £30,000. Businesses with a turnover exceeding £50,000 will be asked to join MTD from April 2026 after which the threshold of £30,000 will apply from April 2027.
The £30,000 threshold applies to individuals. So, if you rent property jointly (splitting the income 50/50), you may not need to comply with MTD until your joint rental income exceeds £60,000.

Deferrals / exemptions - there are very few. Most sole-traders and landlords must be compliant from April 2026, Partnerships from April 2027. Partnerships with a corporate partner and LLP's will have a deferred sign-up date, and entities such as Trusts, Estates of deceased persons, Trustees of pension schemes and non-resident companies look likely to be exempt.
Penalties - When a filing deadline for quarterly updates and year end submissions is missed, a point is received. A £200 penalty is issued on reaching a set threshold, any other late filings will trigger a further £200 penalty. The penalty position is reset following a set period of compliance.
What info will be submitted to HMRC? - Total sales and totals of expenses by category. Year-end accounting and tax adjustments will be made via a final submission for the year known as the end-of-period statement (EOPS).
When will submissions be required? - The quarterly filing deadlines will be: 5 August, 5 November, 5 February, and 5 May (i.e. 5 May deadline for the final quarter ending 31 March - 5 April each year)
How will the tax position be finalised? - The EOPS will have to be submitted by 31 January following the end of the tax year, somewhat similar to the current requirement to submit a Self-Assessment Tax Return.
Payment of tax - The existing SA due dates and payment options do not change under MTD.
