Key MTD rules explained simply
Over £50,000 from 6 April 2026
Sole traders and landlords with qualifying income above £50,000 based on the 2024/25 tax return join MTD ITSA from April 2026.
Over £30,000 from 6 April 2027
The threshold drops to £30,000 of qualifying income, based on the 2025/26 tax return.
Over £20,000 from 6 April 2028
The threshold then reduces to £20,000 of qualifying income, based on the 2026/27 tax return.
Qualifying income definition
Qualifying income is gross income from self-employment and property combined, before deducting expenses.
Quarterly updates
Summary income and expenses are submitted to HMRC every three months through MTD-compatible software.
Final declaration
The year-end final declaration confirms personal allowances, other income, reliefs and the final tax position.
Not everyone is in scope
Most limited companies, partnerships with corporate partners and some specific groups are outside MTD ITSA at launch.
Penalties redesigned
A new points-based late submission and late payment penalty regime applies under MTD.
The VMK approach
Confirm your start year
We check your qualifying income for each test year so you know exactly when MTD applies.
Plan the transition
Clear steps, deadlines and software options so the switch to MTD is smooth, not stressful.
Set up MTD software
Choose and configure a compatible system that fits how you trade or let property.
Handle quarterly updates
We review the numbers and submit each quarterly update to HMRC on your behalf.
Manage the final declaration
Allowances, reliefs, other income and adjustments tied together into the final declaration.
Ongoing tax planning
Quarterly visibility means proactive advice on profit, tax and cash flow, not just an annual catch-up.
What to avoid
Assuming MTD only applies once you are over £50,000 - the threshold drops to £20,000 by April 2028.
Looking at profit instead of gross qualifying income.
Forgetting to add rental income to self-employment income when checking the threshold.
Leaving software setup until the year MTD starts.
Missing quarterly deadlines and triggering new penalty points.
Not keeping digital records throughout the year, which makes quarterly updates inaccurate.
