TL;DR (Key Takeaway for Busy Sole Traders)

If you’re a UK sole trader, you must keep digital records of your income and expenses and submit updates to HM Revenue & Customs (HMRC) under Making Tax Digital for Income Tax (MTD ITSA) which starts in the 26-27 tax year.

To stay compliant without an accountant:

Record every payment you receive
Record every business expense
Keep digital records (not a paper notebook)
Use MTD-compatible software
Submit quarterly updates to HMRC

It’s not about being “good at tax.” It’s about being consistent and organised.

And yes — you can absolutely do this yourself.

The Problem: “I Just Want to Do the Work… Not the Paperwork”

You started freelancing to design, build, teach, fix, create — not to become a part-time bookkeeper.

But here’s the reality:

From April 2026 (if your income is over £50,000) and April 2027 (if over £30,000), MTD for Income Tax becomes mandatory for most sole traders.

This means:

No more once-a-year scramble
No more guessing numbers in January
No more “I’ll sort it later”

You’ll need digital records, updated throughout the year.

The good news? This is much simpler than it sounds.

Let’s break it down.

Step 1: Record Your Income (Every Pound That Comes In)

Your income is simply:

All money you receive for your business work.

This includes:

Client payments
Cash jobs
Bank transfers
Stripe or PayPal payments
Tips (if applicable)

If someone pays you for your work — it’s income.

What to record

For each payment:

Date received
Amount
Who paid you
Short description (e.g. “Website design – March project”)

That’s it.

You do not need complex accounting codes. You do not need to understand debits and credits.

Think of it like keeping a scoreboard.

Step 2: Record Your Expenses (What You Spend to Run Your Business)

Expenses are business-related costs.

Common examples:

Laptop
Software subscriptions
Phone bill (business portion)
Travel to client meetings
Insurance
Marketing costs
Office supplies

If it’s wholly and exclusively for business, it’s usually allowable.

(“Wholly and exclusively” just means it’s genuinely for business, not personal.)

Visual Guide: Common Allowable Expenses

Expenses You Can’t Claim

To keep things simple:

Everyday clothes (even if you wear them for work)
Your weekly food shop
Personal holidays
Gym memberships (unless directly business-related)

When in doubt, ask:

“Would I be buying this if I didn’t run this business?”

If the answer is no — it’s likely allowable.

Step 3: Keep Digital Records (Paper Isn’t Enough Anymore)

Under Making Tax Digital (MTD), you must:

Keep records digitally
Use MTD-compatible software
Submit quarterly summaries to HMRC

A spreadsheet can technically count if connected properly, but in practice it becomes messy fast.

This is where software helps.

Step 4: Submit Quarterly Updates to HMRC

Instead of one big annual tax return, MTD requires:

4 quarterly updates
1 final declaration at year-end

Think of it like sending HMRC a progress report.

It’s not paying tax four times — it’s just reporting more regularly.

“Do I Really Need an Accountant?”

Not necessarily.

Many sole traders:

Have straightforward income
Have simple expenses
Don’t employ staff
Aren’t VAT registered

If that’s you, you can likely manage this yourself.

Accountants are fantastic for complex situations.

But if your business is simple, your bookkeeping should be too.

Why Full Accounting Software Feels Overwhelming

Tools like:

Xero
QuickBooks
FreeAgent

are powerful.

But they’re built for:

Limited companies
Payroll
VAT
Inventory
Multi-user teams

If you’re a solo freelancer, it can feel like using a spaceship to make a cup of tea.

What You Actually Need

If you’re a sole trader preparing for MTD ITSA, you need software that:

Tracks income
Tracks expenses
Keeps digital records
Submits to HMRC
Doesn’t overwhelm you

That’s it.

No charts of accounts headaches. No accounting degree required.
