Making Tax Digital for Freelancers: The 2026 Guide

What Making Tax Digital for Income Tax actually changes

Making Tax Digital for Income Tax Self Assessment (MTD for ITSA) is the second major phase of HMRC's digital tax programme, after Making Tax Digital for VAT. It replaces the once-a-year Self Assessment tax return for affected sole traders and landlords with a new cycle: digital record-keeping throughout the year, four quarterly updates sent to HMRC through compatible software, an end of period statement for each income source, and a final declaration at year end. If you already keep your invoicing and expenses in software rather than a shoebox of receipts, the practical change is smaller than it sounds. If you currently do one big Self Assessment push in January, it is a meaningful shift in how often you touch your books.

This guide covers MTD for Income Tax specifically. If you are VAT-registered, VAT has its own separate MTD regime that has applied to all VAT-registered businesses since April 2022 — see our Making Tax Digital for VAT guide for that.

Who has to join, and when

MTD for Income Tax applies to sole traders and landlords registered for Self Assessment whose qualifying income is above the threshold for that tax year. Qualifying income is your total gross income from self-employment and property combined, before expenses. HMRC works this out from the income you already declared on a previous Self Assessment return, so there is no separate sign-up assessment to make.

Because the threshold is based on gross turnover and not profit, it is easy to underestimate whether you are caught. A freelancer billing £55,000 a year with £15,000 of expenses has a profit of £40,000, but a qualifying income of £55,000 — comfortably over the £50,000 threshold. Check your total invoiced income for the year, not your take-home profit, when working out whether you are affected.

If you have more than one qualifying income source (for example, freelance work plus a rental property), the two are added together for the threshold test, even though you will submit separate quarterly updates for each business or property.

What you need to do differently

Once you are required to join MTD for Income Tax, three things change:

1. Digital records. You must keep records of your business income and expenses digitally, in MTD-compatible software, rather than in a paper cashbook or an unconnected spreadsheet.
2. Quarterly updates. Four times a year you send HMRC a summary of income and expenses for that quarter, using software that connects to HMRC's MTD service.
3. End of period statement and final declaration. After the fourth quarterly update, you submit an end of period statement for each business or property income source, confirming and finalising the figures, then a final declaration that replaces the old Self Assessment tax return.

Quarterly update deadlines

The default quarters run to the tax year (6 April to 5 April), though you can elect to use calendar quarters instead. For the standard tax-year quarters, the deadlines are:

You do not need to wait until the deadline — you can send an update any time after the quarter ends. Many freelancers find it easiest to submit as soon as the quarter closes, while the invoices and expenses are fresh.

Penalties for missing deadlines

Late submission uses a points-based system. Each missed quarterly update or tax return deadline earns one penalty point. Once you reach 4 points, you get an immediate £200 penalty, and a further £200 for every deadline you miss after that. Points below the 4-point threshold expire automatically 24 months after the missed deadline. Late payment penalties are separate and are not points-based: there is no penalty in the first 15 to 30 days after the payment deadline (the exact grace period is being phased in), then a percentage-based penalty applies and escalates the longer the amount stays unpaid, with daily interest running from day 31.

What counts as compatible software

HMRC does not provide its own software for MTD for Income Tax. You need third-party software recognised by HMRC that can keep digital records and send updates directly through the MTD API. You can use a spreadsheet for your underlying records provided you connect HMRC-recognised bridging software to submit from it, but most freelancers find it simpler to use invoicing or bookkeeping software that keeps records digitally from the point of sale, so nothing needs to be re-entered later.

Tidybill keeps a permanent digital record of every invoice you issue and every payment you receive, which is the record-keeping foundation MTD for Income Tax requires. Direct quarterly submission to HMRC from within Tidybill is on the roadmap; in the meantime, export your income summary each quarter and submit it through HMRC-recognised bridging software or your accountant.

Practical steps to prepare

• Work out your qualifying income from your last Self Assessment return to see which threshold year applies to you.
• Move off paper and spreadsheets for invoicing and expense tracking well before your start date, so the habit is already in place.
• Separate your business and personal transactions if you have not already — a dedicated business account makes quarterly summaries far faster to produce.
• Diarise the quarterly deadlines (7 August, 7 November, 7 February, 7 May) rather than relying on a single January push.
• Talk to your accountant about which software they support and whether they will submit on your behalf.
