Answers before the deadline, not after it.

Two questions we get asked every week, worked out on screen in under two minutes. Nothing is saved, nothing is sent anywhere, and you do not have to give us an email address to see the answer.

01

Do you need to file under MTD?

Making Tax Digital for Income Tax replaces one annual return with four quarterly updates plus a final declaration. Whether it applies to you, and from when, depends on your gross self-employment and property income.

MTD ITSA eligibility
01 / 04

Do you have income from self-employment or UK property?

Sole trade, freelancing, a rental property, or a share of one. Employment, dividends and pensions do not count here.

What is your gross income from those sources?

Total turnover and rent for a full year, before any expenses. Estimate for the year from April 2026 if you are not sure.

£

Do you have a UK National Insurance number?

Without one by 31 January before the tax year, you are automatically outside MTD for that year. This mostly affects non-resident landlords.

Have you already filed at least one Self Assessment return?

MTD only starts after your first return has been submitted. If you are newly self-employed, your start date moves back a year.

Result
APRIL 2027

Your gross income is between £30,000 and £50,000, so quarterly updates start from April 2027.

From then you send four quarterly summaries of income and expenses per business, plus a final declaration by 31 January. Each update is cumulative from 6 April. Penalty points apply per missed update and four points is a £200 fine, though HMRC has said no points will be given for late quarterly updates in the first year, 2026/27.

A calculator is not advice

What it does

Applies the published rates and thresholds to the numbers you type, in the browser, on your own machine.

What it misses

Pension contributions, student loans, other income, marginal relief edge cases, a spouse, and the year you actually want the money in.

What we do

Run the same sums against your real accounts before the year end closes, while the answer can still be changed.

Get the number checked against your actual accounts.

A short consultation, free of charge, followed by a written proposal with the scope and the fee in full.
