The Final Countdown: A 4-Week MTD Action Plan for Sole Traders (April 2026 Edition)

If you have been burying your head in the sand regarding Making Tax Digital (MTD) for Income Tax, you are not alone. As an ecommerce accountant UK sellers rely on, I see it every day: TikTok creators and Amazon sellers focused on scaling ads and sourcing products, hoping the tax man will just… wait.

But with April 2026 looming, the "wait and see" phase is over. If your gross income (turnover, not profit) is over £50,000, the way you report to HMRC changes fundamentally on April 6th.

This isn’t just about bureaucracy; it’s about ensuring your business survives the transition without fines. Here is a practical, four-week battle plan to get you compliant without losing your mind.

‍

Are You Ready? The April 6th Deadline Explained

There is a lot of noise about MTD, so let’s cut to the chase.

What is changing? Sole traders and landlords with a qualifying income over £50,000 must keep digital records and send quarterly updates to HMRC using compatible software. The old "do it all in January" self-assessment routine is ending for you.

Who does this affect in April 2026?

• Sole Traders: With gross income over £50k.
• Landlords: With property income over £50k.
• Note: If you earn between £30k and £50k, your deadline is likely April 2027, but starting early is smart.

What this means for you: You can no longer rely on a spreadsheet or a shoebox of receipts. HMRC requires a digital link between your bank transactions and your tax return.

‍

Week 1: The "Shoebox Audit" (Digitising Historical Data)

Your first week is about changing habits. The biggest hurdle for most ecommerce sellers isn't the software; it's the paper trail.

If you are still printing invoices from Alibaba or keeping physical receipts for postage, stop. MTD requires digital evidence.

Action Plan:

• Download a Capture App: Tools like Dext or Hubdoc are non-negotiable. They extract data from receipts via your phone camera.
• Centralise Your Invoices: Create a dedicated email address (e.g., bills@yourbrand.com) and redirect all supplier invoices there. Connect this to your accounting software.
• The "Backlog" Blitz: If you have a pile of paper from the last few months, spend this week scanning them. Once they are digital and backed up, you can technically shred the paper (though keeping them for a short while for peace of mind helps).

Pro Tip: Don’t try to organise them perfectly yet. Just get them digital.

‍

Week 2: The Setup (Connecting Bank Feeds & Payment Gateways)

This is where it gets technical. As an ecommerce accountant UK brands trust, I can tell you that "connecting your bank" is harder than it sounds for online sellers.

You aren't just connecting Barclays or Monzo. You are connecting the "hidden" bank accounts: Amazon Pay, Shopify Payments, Stripe, and PayPal.

The Creator/Affiliate Software Gap

Here is the honest truth that most software companies won't tell you: The integration software for creators and affiliates doesn't really exist yet.

If you are a TikTok Shop affiliate or an influencer earning commission, Xero and QuickBooks struggle to pull that data cleanly. The platforms (TikTok, Instagram) provide terrible financial statements that don't sync via API like a standard bank feed.

Action Plan:

• Separate Business Banking: If you are using a personal account for business, stop immediately. Open a Starling, Tide, or Monzo business account.
• Connect Major Feeds: Link your main business account to Xero/QuickBooks.
• The Manual Workaround: For TikTok Shop affiliate payouts, you will likely need a manual spreadsheet bridge until the software catches up. We help our clients build these templates to ensure the data is MTD-compliant.

‍

Week 3: The Dry Run (Simulating a Quarterly Update)

By week three, your data is digital and your feeds are live. Now, we simulate the new reality.

Under MTD, you must submit a summary of income and expenses every three months. You don't pay tax then, but you must report the data.

Why do a dry run?

Most sellers discover that their gross profit looks wrong because they haven't accounted for platform fees properly. If Amazon deposits £1,000, you might have actually sold £1,500 worth of goods, with £500 taken in fees and ads. If you only report the £1,000, your turnover looks lower than it is, but your margins look terrible.

Action Plan:

• Reconcile One Month: Go through last month's transactions. Match every payout to a sales report.
• Check the VAT Threshold: Even if you aren't VAT registered, accurate MTD records often reveal you are closer to the £90k VAT threshold than you realised.
• Review with an Accountant: This is the best time to have an expert look at your "digital hygiene" before it goes to HMRC.

‍

Week 4: The Final Review (Verifying Income Thresholds)

It is crunch time. Before the April 6th start date, you need to be 100% sure you actually need to sign up.

Turnover vs. Profit

The £50,000 threshold for April 2026 is based on Qualifying Income (turnover), not your profit.

• Scenario: You sold £60,000 worth of stock on Shopify. You spent £40,000 on ads and stock. Your profit is £20,000.
• Verdict: You MUST comply with MTD because your turnover (£60k) is over the threshold.

Action Plan:

• Check All Income Sources: Combine self-employment income and property income.
• Register for MTD: If you have an accountant, we usually handle this. If not, you need to sign up via your government gateway account—but ensure your software is ready first.

‍

Day 1 (April 6): What Your New Routine Looks Like

Welcome to the new era. The deadline has passed. What does your Monday look like now?

Ideally, it looks boring.

The goal of MTD isn't to increase your workload; it's to smooth it out. Instead of a "January Panic," you adopt a "Friday Review." Spend 15 minutes every Friday snapping receipts and reconciling the bank feed.

Your MTD Calendar:

• Quarter 1: April 6 – July 5 (Deadline: Aug 5)
• Quarter 2: July 6 – Oct 5 (Deadline: Nov 5)
• Quarter 3: Oct 6 – Jan 5 (Deadline: Feb 5)
• Quarter 4: Jan 6 – April 5 (Deadline: May 5)

‍

The "Emergency Cord": What to Do If You Can't Meet the Deadline

If you are reading this on April 4th and haven't started, don't panic—but do act fast.

HMRC uses a points-based penalty system for late submissions. You won't be fined immediately for one mistake, but points rack up, eventually leading to £200 fines.

If you are overwhelmed:

1. Don't ghost HMRC.
2. Get a bridging solution. There are temporary options that allow you to upload spreadsheets to HMRC if you aren't fully set up on cloud software yet.
3. Call us.

As a specialist ecommerce accountant UK businesses rely on, we can step in, tidy up the historical mess, and handle the digital submissions for you. We understand the specific pain of TikTok payouts and Amazon settlements that high-street accountants just don't get.
