Free MTD software for sole traders 2026: what actually counts

Short answer: yes, there is genuinely free, HMRC-recognised software for Making Tax Digital for Income Tax (MTD ITSA) - but check the live list on GOV.UK rather than trusting a blog claim. MTD ITSA is staged: if your qualifying income was over £50,000 for 2024/25 you need to use it from 6 April 2026; over £30,000 for 2025/26 from 6 April 2027; over £20,000 for 2026/27 from 6 April 2028. InvoiceAdept helps UK trades raise clear invoices and keep job records (Free: 5 invoices; Pro £7.99; Pro+ £12.99). It does not file MTD quarterly updates, VAT returns, CIS300 or Self Assessment - use HMRC-recognised MTD software for the filing duty.

This page is for sole traders (and landlords in outline) who want a straight UK answer: when MTD bites, what "free" actually means, how VAT and CIS sit beside it, and what InvoiceAdept is for. No fake stats. Last reviewed: 14 September 2026. Need a PDF invoice now? Open the free invoice generator.

When does MTD become mandatory for sole traders?

Making Tax Digital for Income Tax is rolling out in stages. HMRC looks at your qualifying income (broadly self-employment and property income before expenses - use GOV.UK's checker, do not invent a shortcut).

If you are under the relevant threshold you may stay on ordinary Self Assessment unless you join voluntarily. Always confirm against the live GOV.UK guidance: find out if and when you need to use MTD for Income Tax.

What MTD compliance actually requires

MTD is not just a new annual return. In outline you need:

• Digital records of income and expenses in compatible software (a paper book alone is not enough for the MTD duty).

• Quarterly updates sent to HMRC through that software.

• An End of Period / finalising step for the tax year through compatible software (dates and labels follow HMRC's live guide).

• Software HMRC recognises for MTD for Income Tax - pick from HMRC's list, not from marketing adjectives on a blog.

Exact quarterly deadlines and calendar-vs-standard update periods sit on GOV.UK. Soften absolute claims when your accountant sets a different update pattern.

What counts as genuinely free MTD software?

"Free" on the internet often means a trial, a watermark, or a card on file. For MTD, treat free as:

InvoiceAdept's Free plan is free invoicing for 5 invoices - useful for raising PDFs and job paperwork. It is not a substitute for HMRC-recognised MTD ITSA filing software. Do not treat "free invoice generator" as "free MTD filing".

How VAT and CIS sit beside MTD

A plumber can be under MTD ITSA, VAT-registered, and paid under CIS by a main contractor on the same job - three different systems. Keep the invoice clear; let recognised tax software / your accountant handle filings.

A practical free-path checklist

1. Confirm whether you are in scope using GOV.UK's MTD Income Tax guidance and qualifying-income rules.

2. Pick HMRC-recognised MTD ITSA software from the official list (free tier if one fits your turnover and features).

3. Keep digital income/expense records from the start date that applies to you.

4. Send quarterly updates on time through that software.

5. Keep customer invoices tidy in parallel - the free invoice generator covers five PDFs on Free; upgrade to Pro (£7.99) or Pro+ (£12.99) when you need more.

If HMRC has already written to you about MTD for Income Tax, treat that letter as the prompt to pick recognised software and line up digital records - do not wait for the first quarterly deadline to invent a process. Soften: your accountant may already have a preferred MTD product; align with them before migrating books mid-year.

What InvoiceAdept is (and is not) for

InvoiceAdept is UK trade invoicing software: sequential invoices, clear line items, CIS/VAT-aware templates on the blog, and a free generator at /invoice-builder/.

Older marketing lines that said "unlimited free invoices" or "MTD-ready quarterly exports" on this URL were wrong - this rewrite corrects them.

Common mistakes around free MTD

Records you should keep even before MTD filing software is chosen

Whether or not you are in the April 2026 cohort, clean source records make both invoicing and tax software easier:

• Dated invoices with unique numbers (the free invoice generator helps here).

• Bank feeds or statements that match invoice totals.

• Expense evidence (receipts, materials, subcontract) tied to jobs.

• CIS payment and deduction statements when a contractor pays you under CIS.

• VAT invoices and workings if you are VAT-registered (threshold framing £90,000).

Those records are not a substitute for HMRC-recognised MTD ITSA software when you are mandated - they are the inputs that software and your accountant will rely on.

How trades usually combine tools

A common UK trade setup looks like this:

Trying to force one app to be "everything" is how people buy the wrong free plan. Keep invoicing and tax filing clear.
