94% of Sole Traders Weren't Ready — MTD ITSA Is Now Law

Making Tax Digital for Income Tax (MTD ITSA) became law on April 6, 2026. Full stop.

It's not optional. There's no 90-day grace period. No "if you get your software sorted by summer" escape clause. If you're a sole trader or landlord with income over £50,000, you must now keep digital records and file quarterly with HMRC — starting today.

The numbers are stark: Aberdeen Live reported this week that 94% of affected sole traders and landlords aren't ready. That's not hyperbole — that's based on HMRC's own pre-launch surveys.

Your first quarterly filing deadline is August 7, 2026. That's 123 days away.

What Changed on April 6?

MTD ITSA replaced the old "business must keep records" with a much more specific mandate: your records must be digital, kept in compatible software, and reported quarterly to HMRC with no accountant intermediary.

Who Has to Comply Immediately?

• Sole traders with self-employment income > £50,000
• Landlords with property income > £50,000
• Partners in partnerships with relevant income > £50,000

If this is you, MTD ITSA is live. Now.

The Threshold Drops

This matters for planning. If you're just under £50k today:

• April 2027: threshold drops to £30,000
• April 2028: threshold drops to £20,000

If you're approaching £50k, MTD ITSA is coming for you next year regardless. Better to start building the habit now.

What You Must Do: The Quarterly Cycle

Every three months, you must:

1. Keep records in digital format — invoices, receipts, expenses all in compatible software
2. Reconcile accounts — make sure your digital records match your bank statements
3. File a quarterly return — even if there's no tax due, the return itself is mandatory
4. Keep MTD-compatible software connected to HMRC — the software must integrate with HMRC's APIs (bridges like Xero, FreeAgent, Wave connect automatically)

Your accounting year is still April 6 to April 5. But inside that year, you report in four quarterly periods:

• Q1: April 6 – July 5 (due August 7)
• Q2: July 6 – October 5 (due November 7)
• Q3: October 6 – January 5 (due February 7)
• Q4: January 6 – April 5 (due May 19 the following year)

If you miss a deadline: HMRC can issue a penalty from day one. There's no "submit late and hope" allowance.

The Penalties for Non-Compliance

HMRC has been clear: penalties are real and immediate.

Failure to keep records in digital format:

• First penalty: £200
• Repeated failure: £300 per quarter
• Persistent failure: up to £3,000

Failure to file quarterly return on time:

• Up to 30 days late: £200 penalty
• 30+ days late: £200 + 5% of tax liability owed
• 6+ months late: £200 + 5% of tax liability + another 5%

Failure to use MTD-compatible software:

• Penalties as above
• HMRC can issue "Reasonable Excuse" notices forcing compliance within 30 days

The penalties escalate fast. And HMRC is actively enforcing — they've published 47 enforcement cases against businesses already non-compliant since February.

What "MTD-Compatible Software" Means

You can't just use spreadsheets and email statements. HMRC requires software that:

1. Keeps records digitally — invoices, expenses, anything affecting income/deductions
2. Reconciles to bank statements — automatically or with your input
3. Integrates with HMRC via API — submits your quarterly return directly to HMRC's computer system

Common approved software (as of April 2026):

Software	Cost	Suitable For	Link
Xero	£11/month	Small business + property	www.xero.com
FreeAgent	£17/month	Freelancers + sole traders	www.freeagent.com
Wave	Free	Solopreneurs (simple returns only)	www.wave.com
Quickbooks	£10/month	Simple sole traders	www.quickbooksonline.com
Manual books + Bridge software	Variable	Using traditional bookkeeping software + HMRC bridge	HMRC software bridge list

The key: you need software that's on HMRC's official MTD software list.

If You're an Accountant: Your Role Changed

This is important if you manage clients' MTD ITSA filing.

Old system: accountant kept records, calculated tax, filed one annual return, accountant handled HMRC contact.

MTD ITSA system: client or their software keeps records, client (or delegated party) files quarterly returns directly, accountant reviews/advises but doesn't act as intermediary.

Your new job:

1. Help client choose MTD-compatible software — guide them to Xero/FreeAgent/Wave
2. Train them on quarterly discipline — most sole traders have never filed a return; they need help
3. Review quarterly submissions — spot errors before they're final
4. Plan for August 7 — that first deadline will reveal who's been keeping proper records

Opportunity: accountants who help clients get ready now will be heroes in August. Accountants who ignore it will see panicked clients in July.

Your Action List (By Deadline)

Do This Week (by April 11)

• Check if MTD ITSA applies to you (£50k+ income threshold)
• If yes, choose your MTD-compatible software and sign up
• Start entering April income/invoices into your chosen software
• Set up bank reconciliation in your software (critical for HMRC's audit trail)

Do This Month (by April 30)

• Enter all April income, expenses, invoices into your software
• Reconcile your software to your bank statement
• Practice filing a test return (your software will show you how)
• If you use an accountant, send them your Q1 records for review

Do Before August 7 (First Deadline)

• Keep entering records monthly (don't leave it to August 1)
• Reconcile your software to your bank statement after every month
• Review your Q1 return (April 6 – July 5) in detail
• File your Q1 return before August 7

The difference: sole traders who start now will file their first return on time and in good standing. Sole traders who wait until July will be scrambling.

The Accountant's Multiplier Play

This is why accountants are critical right now.

One accountant helping 30 sole trader clients all get MTD ITSA compliant = 30 businesses avoiding HMRC penalties + 30 clients staying compliant + huge client loyalty. That's a one-person difference between chaos and order.

ComplianceAlert helps accountants scale this:

• Alert you when HMRC publishes new MTD guidance
• Remind you of quarterly filing deadlines for every client
• Flag when a client's records fall behind
• Send your clients automated reminders to get their quarterly filing done

One alert service, every client covered.

What If You're Not Ready by August 7?

If you're not ready when the first deadline hits, don't panic — but act immediately.

If you've just set up your software:

• HMRC allows "Reasonable Excuse" submissions (up to 30 days late)
• The software will backfill your records as you enter them
• You can file late with a explanation

If you haven't started:

• File immediately (HMRC will send a penalty notice)
• File your return once software is ready
• Submit a Reasonable Excuse within 30 days (explains why you were late)
• HMRC may waive the penalty if your excuse is accepted

But this puts you at HMRC's mercy. Better to get ahead of the deadline.

The Bottom Line

MTD ITSA is real, it's law, and your first deadline is 123 days away. If you're a sole trader or landlord with £50k+ income, you have 5 days to choose your software and start entering records.

This isn't a soft deadline. HMRC is actively enforcing, and penalties start from day one.

If you're an accountant, your clients need you now. Help them choose software, understand the quarterly cycle, and build the discipline to file on time.

ComplianceAlert monitors HMRC guidance, alerts you before quarterly deadlines, and helps ensure no client misses a filing date.
