Making Tax Digital for Small Business: What You Need to Know in 2026

What is Making Tax Digital?

Making Tax Digital (MTD) is HMRC's programme to digitise the UK tax system. The goal: businesses and self-employed individuals keep digital records and submit tax information to HMRC using compatible software — instead of paper records and annual self assessment returns.

MTD for VAT has been mandatory since April 2019 (for businesses above the £85,000 threshold) and extended to all VAT-registered businesses from April 2022. MTD for Income Tax Self Assessment (MTD ITSA) is the next phase.

MTD for Income Tax: who is affected and when

The rollout of MTD ITSA is happening in stages:

If you're self-employed with a turnover above £50,000, MTD ITSA applies to you from April 2026 — which means you need to be preparing now.

What changes under MTD ITSA

Under the current system, you submit one self assessment return per year (by 31 January). Under MTD ITSA:

1. Quarterly updates: you submit a summary of your income and expenses to HMRC every quarter (by the 7th of the following month after each quarter ends)

2. End of period statement (EOPS): once per year, you finalise your figures and confirm your tax position

3. Final declaration: replaces the current self assessment return — submitted by 31 January following the tax year end

The quarterly updates are not tax payments — they're just information submissions. Your actual tax bill is still calculated annually.

Digital record keeping: what this means in practice

MTD requires you to keep digital records of all business income and expenses. This means:

Spreadsheets alone are not MTD-compliant. You need software that can submit directly to HMRC via the MTD API.

The quarterly submission deadlines

Missing a quarterly deadline incurs a points-based penalty system: accumulate enough points and you'll receive a financial penalty. HMRC has confirmed a "soft landing" for the 2026/27 tax year: no penalty points will be issued for any of the first four quarterly updates for taxpayers newly mandated from April 2026.

Exemptions from MTD ITSA

You may be exempt if:

Apply for an exemption via HMRC's online service before your MTD start date.

How to prepare now

1. Start keeping digital records today: even if your threshold date is April 2027, building the habit now makes the transition easier.

2. Choose MTD-compatible software: you'll need a tool that can submit quarterly updates to HMRC directly. Check the HMRC software finder.

3. Review your record keeping process: do you have a system for capturing every receipt and invoice at the time of the transaction? WhatsApp photo → automatic extraction is one approach.

4. Speak to your accountant: MTD changes the workflow for accountants too. Check that yours is set up to handle quarterly data rather than a single year-end drop.

How Syntra helps with MTD readiness

Syntra captures and categorises income and expenses in real time — the core of what MTD requires. Every invoice you upload (photo, PDF, or via WhatsApp) is extracted, categorised and stored digitally with a timestamp and full audit trail.

This gives you the digital record foundation that MTD ITSA requires: every transaction captured at the time it happens, with vendor, amount, category, and VAT treatment — ready to pull into a quarterly summary.
