April 6th, 2026 is the hard line. If you’re self-employed or a landlord earning over £50,000, Making Tax Digital (MTD) for Income Tax becomes mandatory. No exemptions. No delays. This isn’t a suggestion. If you advise businesses or manage your own finances, you need to understand what’s happening and start preparing now. ## What Changes Making Tax Digital ends the annual tax return cycle. Here’s what replaces it: **Quarterly submissions.** Instead of filing once in January, you’ll submit summaries to HMRC four times a year. Your first submission is due by August 7th, 2026, covering April 6th to July 5th. **Digital records only.** No spreadsheets that sit on a hard drive. No paper backups. Records must be kept digitally from day one. **Compatible software.** You can’t submit free-form data. You need to use HMRC-approved software that connects to their API. The software does the talking to HMRC. **The threshold.** Currently it applies to gross income above £50,000. This includes self-employed people, freelancers, and landlords with rental income. Income, not profit—so a £55,000 rental income counts even if your profit is lower after expenses. Worse: the threshold drops to £30,000 from April 2027. That brings in micro-businesses and part-time freelancers. ## Why This Matters for CFOs If you run a finance function, you manage people handling business finances. If you’re a business owner yourself, this affects your own tax planning. **The operational burden is real.** Quarterly filing means you can’t treat tax as a January affair anymore. You need close processes happening four times a year. That’s resource. That’s training. That’s process design. **Data quality matters immediately.** With quarterly submissions, HMRC gets a real-time view of your cash and expenses. They use this data to cross-reference against your bank statements and other filed information. Dodgy records used to hide until the annual review. Now HMRC sees discrepancies within weeks. **Penalties are sharp.** Miss a quarterly deadline and the penalty starts at £100. Miss it again and it rises. Three months late gets you a different penalty. There’s also interest on unpaid tax. This compounds quickly. **The software cost.** You’ll need to buy or subscribe to compatible software. Accountancy firms are raising prices. Some charge monthly subscriptions. This is a real cost for businesses that currently use free spreadsheet-based record keeping. ## Who Has to Comply (and Who Doesn’t) **You must comply from April 2026 if:** – You’re self-employed with gross income over £50,000 – You’re a landlord with rental income over £50,000 – You’re in a partnership and your share of income exceeds the threshold **Exemptions exist but are narrow:** – Accountants and agents can apply for a temporary exemption until April 2027 – Income below £50,000 is exempt for now (but plan for £30,000 from 2027) – Partnerships and trustees have modified rules (you still file quarterly, but through different channels) ## What to Do Right Now **Month 1: Understand your position.** Are you or your clients affected? Calculate gross income for the last tax year. If it’s over £50,000, MTD applies. **Month 2: Choose software.** HMRC publishes an approved list of providers. Don’t guess. Test one with dummy data. Ensure it handles your specific business type (landlord, freelancer, etc.). Popular choices include FreeAgent, Crunch, and Xero, but there are 40+ options. **Month 3: Audit current records.** Where are your records? Spreadsheets? An old accounting file? Shoebox of receipts? You need to consolidate everything into digital format before April. This is the phase that surprises people—it’s messy. **Month 4: Set up quarterly processes.** You can’t continue managing finances annually. Accounting close happens in January, April, July, and October at minimum. Create a calendar. Assign owners. Write down what data you need to pull, who signs off, and when the submission happens. **Ongoing: Test the filing process.** File a test return in the software before your first live submission. Learn the interface. Understand the error messages. There’s nothing worse than discovering filing problems on August 5th when your deadline is August 7th. ## The Wider Context MTD isn’t a one-off change. It’s the start of a shift toward real-time tax reporting. HMRC has already moved corporation tax returns to a digital-first model. Individual income tax is next. The goal is to reduce the compliance burden and increase real-time visibility into the tax system. This means: – Future changes will likely extend MTD to more taxpayers (already coming in 2027 at the lower threshold) – Integration between software platforms will improve but take time – Your record-keeping standards should assume permanent digital-first from now on ## Common Mistakes to Avoid **Starting too late.** April is closer than it feels. Software selection alone takes a month if you do it properly. **Assuming your accountant will handle it.** Many accountants struggle with MTD workflow. You need to understand your role. You provide clean data; they file it. **Mixing records.** Keep personal and business finances separate. If you’re a director taking a salary plus dividends, don’t lump it all together. Separate accounts from the start. **Ignoring the threshold drop.** If you’re at £35,000 in income now, you’re safe until 2027. But you should still prepare systems for the lower threshold because it’s coming. ## Next Steps Talk to your accountant about their MTD capabilities. Ask whether they’ve filed test returns. Ask who handles issues if something goes wrong on submission day. If you’re a business owner, start evaluating software this month. Don’t leave it to February. The software choice affects how you organize records for the entire year. If you’re a CFO managing multiple businesses, standardize on one or two platforms across your portfolio. Consistency makes audits easier and reduces errors. Making Tax Digital is genuinely complex, but it’s not impossible. The businesses that move now will file cleanly in August. The ones that delay will be scrambling in July. If you’re unsure how to prepare your business or your clients for MTD, let’s talk. Tax compliance is changing fast, and April is the deadline that doesn’t move. Get in touch to discuss your MTD readiness and next steps.
