The 6th of April is just around the corner. And honestly? For sole traders, it's the best day in the calendar.
Not because tax is fun. It isn't. But a new tax year is one of the rare moments where you genuinely get to start fresh. Whatever happened last year with the receipts you meant to log, the expenses you forgot to track, or the spreadsheet that's been quietly judging you from a browser tab, none of it carries over.
This year, the fresh start matters more than usual for any sole trader. Because from April 2026, if you're earning over £50,000 from self-employment, Making Tax Digital for Income Tax Self Assessment (MTD for ITSA) becomes a legal requirement. That means digital records, quarterly updates to HM Revenue and Customs (HMRC), and a different way of keeping track of your finances throughout the year.
If that sounds like a lot, good news. It isn't. This guide covers exactly what's changing, why 6 April is the perfect moment to build better habits, and how to set yourself up so the whole year feels more like a gentle trot than a mad January scramble.
Why the New Tax Year Is Your Perfect Reset Moment
Think of 6 April like New Year's Day, but for your finances. The slate is genuinely clean. Zero income recorded, zero expenses logged. You haven't made a mess yet, which means you can build a system before you need one.
Most of the stress sole traders feel about tax doesn't come from the tax itself. It comes from playing catch-up. Trying to remember in December whether that software subscription in June was business or personal. Hunting for a receipt from seven months ago. Totting up three different accounts the week before a deadline because nothing was recorded as it happened.
Starting the year with a solid record-keeping routine means none of that happens.
The new tax year runs from 6 April 2026 to 5 April 2027. Under MTD for ITSA, if you earn over £50,000 from self-employment, that's your gross income, before expenses, this is the first year you'll need to comply. Your very first quarterly update will cover April to July 2026, with a submission deadline of 7 August 2026.
That's less than four months away. But if you get set up in the next few days, you won't even notice the deadline come and go.
What MTD for Income Tax Actually Requires (in Plain English)
There's been a lot of noise about Making Tax Digital. Here's what it actually means for your day-to-day, stripped back to the essentials.
Digital records: You need to keep records of your income and expenses digitally. Paper is out. A spreadsheet you then manually copy into another system doesn't count either, HMRC requires digital links throughout.
Quarterly updates: Four times a year, you send HMRC a summary of your income and expenses. Each update is just totals, not individual receipts. If your records are current, filing literally takes minutes.
End-of-year final declaration: At the end of the tax year, you complete a final declaration. Think of it as a tidied-up version of the Self Assessment return you do now, simpler, because your quarterly updates have already done the heavy lifting.
MTD-compatible software: You can't submit directly through Government Gateway anymore. You need approved software that connects directly to HMRC's systems and submits on your behalf.
No new taxes. No extra calculations. Just a more organised way of doing what you already need to do.
The quarterly deadlines for 2026-27 are:
- 7 August 2026, covering 6 April to 5 July
- 7 November 2026, covering 6 July to 5 October
- 7 February 2027, covering 6 October to 5 January
- 7 May 2027, covering 6 January to 5 April
Miss them and you risk penalties. Stay on top of them and they become no more stressful than a quarterly check-in on how your business is doing.
The One Habit That Makes Everything Easier
Here's the single most useful thing you can do for your new tax year: log transactions as they happen, not at the end of the quarter.
That's it. That's the whole thing.
Think of it like doing the washing up after each meal instead of letting it pile up for a week. A few minutes now saves an hour of grimacing later.
Most sole traders don't struggle with record-keeping because it's complicated. They struggle because they leave it. Receipts go missing. Bank imports accumulate. Context goes fuzzy. "What was that £58 in November?" is a much harder question than "What was that £58 from yesterday?"
A simple weekly rhythm, even 15 minutes on a Friday, keeps everything current. When a quarterly deadline arrives, you're not doing a frantic catch-up session. You're checking that everything looks right and pressing submit.
Setting Up Your Records from Day One
The 6th of April is the ideal moment to get set up properly. Here's what a clean record-keeping system looks like in practice.
Record income as it comes in
Every time a payment lands, invoice settled, freelance job paid, retainer received, log it straight away. Each entry takes about 30 seconds. The habit, once built, takes almost no conscious effort.
Capture expenses close to when they happen
You don't need to be obsessive about it. But logging an expense the same day, or within a day or two, means you still remember what it was for. Attach the receipt or invoice if you have it. Under MTD, you need to keep digital records for a minimum of five years, so having everything in one place from the start is well worth it.
Use HMRC-aligned categories from the start
HMRC has specific expense categories: office costs, travel, premises costs, staff, and so on. If you're putting things in the wrong buckets, or piling everything into a vague "general" category, you'll end up doing a lot of sorting at year end.
Good MTD software handles this for you. Categories are set up to match exactly what HMRC expects, so there's no manual translation when it comes time to submit.
Track home office and mileage from day one
These are two of the most commonly under-claimed expenses for sole traders. They're also two of the easiest to forget if you don't build the habit early.
HMRC's mileage rate for cars is 45p per mile for the first 10,000 business miles. Log each journey when you make it, not a rough estimate at year end. For home office, track your working hours and let the flat-rate calculation sort itself.

A Tale of Two Tax Years
Priya is a freelance graphic designer based in Bristol. She earns around £65,000 a year, mostly from regular clients plus occasional project work.
For 2024-25, she managed her records the way she always had, a spreadsheet she updated when she got around to it, which in practice meant a panicked fortnight in January. She filed her Self Assessment on time, but only just, and she was pretty sure she'd missed claiming for a few months of home office.
For 2025-26, she decided to try something different. On 6 April 2025, she set up an MTD tool, connected her bank, and started logging expenses as they happened. Took her 20 minutes on day one and about 10 minutes each week after that.
When MTD came into force for her in April 2026, there was nothing to adjust. She'd already been doing it for a year. Her first quarterly update, 6 April to 5 July, took nine minutes to file, and she caught £340 of home office expenses she would have forgotten under the old system.
The difference wasn't effort. It was timing.
What If You Earn Under £50,000?
MTD for ITSA's April 2026 start applies to sole traders with qualifying income over £50,000. If you earn between £30,000 and £50,000, your mandatory start date is April 2027.
If you're currently below both thresholds, you're not required to comply yet. But here's the honest take: the rules will reach most sole traders eventually. Starting digital record-keeping now, before you have to, is far less stressful than scrambling to comply on a deadline.
It's also just useful. Live estimates of what you owe. Expenses in the right categories. Quarterly snapshots of how your business is actually performing. That's worth having regardless of whether HMRC requires it.

Why April Is the Best Time to Switch Tools
If you've been managing finances in a spreadsheet, or using software that feels more complicated than it should, the new tax year is the natural moment to switch.
You're not mid-year with data scattered across two systems. You're starting clean. One tool. One source of truth. Nothing to migrate except your opening balance.
Switching in April also means you have the full year to get comfortable with quarterly reporting before the next round of deadlines. There's no rush, just a steady rhythm of logging and submitting that becomes second nature by autumn.
When choosing a tool, here's what actually matters:
- Does it use plain-English categories that map to what HMRC expects?
- Can you submit quarterly updates directly to HMRC without a middleman?
- Does it show a live estimate of your tax bill so there are no January surprises?
- Is setup genuinely quick, or does it require a full afternoon?
For a fair comparison of what's out there, our MTD software comparison for sole traders covers the main options side by side.
And if you're making the switch from spreadsheets specifically, our stress-free migration guide walks you through it without any drama.
Your 6th April Checklist
To start the new tax year in good shape, here's what to do on (or before) 6 April:
- Choose your record-keeping tool, and actually set it up, not just download it
- Connect your bank feed so transactions import automatically from day one
- Check your expense categories match HMRC's structure
- Set up mileage and home office tracking if relevant to your work
- Note your first quarterly deadline, 7 August 2026 if you're in scope for MTD
- Block 15 minutes a week in your calendar for a quick finance check-in
That genuinely is it. You don't need to become a bookkeeping expert. You just need a system that runs quietly in the background, so you're never scrambling to catch up.
Start the Year the Way You Mean to Go On
There's something genuinely satisfying about clean records on 6 April. Everything in order. Categories sorted. Bank connected. Ready.
By the time August rolls around and your first quarterly update is due, you won't be panicking. You'll be submitting a few minutes of tidy data and getting on with your actual work.
This new tax year is a proper fresh start. Make the most of it.
