By A Practical Guide for Sole Traders, Landlords & Growing Businesses
Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is one of the biggest changes to the UK tax system in recent years. While the rules are being introduced in phases, UK SMEs that prepare early will save time, money, and stress when MTD ITSA becomes mandatory.
At TT Accountancy Services (TTAS), we are already helping small businesses across London get MTD-ready — long before deadlines arrive.
This guide explains what MTD ITSA is, who it affects, and how UK SMEs can prepare now to avoid last-minute panic.
What Is MTD ITSA?
MTD ITSA is part of HMRC’s Making Tax Digital initiative, designed to modernise the UK tax system.
Under MTD ITSA, affected taxpayers must:
- Keep digital records
- Submit quarterly income and expense updates to HMRC
- Send an End of Period Statement (EOPS)
- Submit a Final Declaration instead of a traditional annual Self-Assessment return
This replaces the once-a-year tax return with more frequent digital reporting.
Who Will Be Affected by MTD ITSA?
MTD ITSA will apply to:
- Sole traders
- Self-employed individuals
- UK landlords
- SMEs earning qualifying income
Based on HMRC’s rollout plan, MTD ITSA will apply to:
- Businesses with annual business or property income over £50,000
- Later phases will include those earning over £30,000
If you file a Self-Assessment tax return today, there is a strong chance MTD ITSA will affect you soon.
Why UK SMEs Should Prepare Early
Waiting until MTD ITSA becomes mandatory can lead to:
❌ Missed deadlines
❌ Incorrect submissions
❌ HMRC penalties
❌ Increased admin costs
❌ Stress and confusion
Preparing early allows you to:
✔ Spread the workload across the year
✔ Understand your tax position in real time
✔ Improve cash flow planning
✔ Avoid rushed decisions
✔ Reduce compliance risks
How UK SMEs Can Prepare for MTD ITSA Now
1. Move to Digital Record-Keeping
MTD ITSA requires digital records — spreadsheets alone may not be enough.
UK SMEs should begin using HMRC-compatible accounting software, such as:
- Xero
- QuickBooks
- Sage
Digital records must include:
- Income dates and amounts
- Expense categories
- Business descriptions
- VAT details (if applicable)
TTAS helps businesses choose, set up, and manage the right software.
2. Get Comfortable With Quarterly Reporting
Instead of one annual return, MTD ITSA requires four quarterly updates.
These updates:
- Are summaries, not full tax bills
- Help HMRC estimate your tax position
- Require discipline and consistency
Preparing now helps you build a routine — rather than scrambling later.
3. Review Your Current Bookkeeping Process
Many SMEs only update records once a year — this won’t work under MTD ITSA.
Ask yourself:
- Are my records always up to date?
- Can I easily identify business income and expenses?
- Do I separate personal and business finances?
If the answer is “no”, it’s time to restructure.
4. Separate Business and Personal Finances
This is one of the most important preparation steps.
✔ Open a dedicated business bank account
✔ Avoid using business funds for personal expenses
✔ Keep clear transaction descriptions
Clean records make MTD ITSA reporting far easier and reduce errors.
5. Understand Your New Filing Obligations
Under MTD ITSA, you’ll be required to submit:
- 4 quarterly updates
- 1 End of Period Statement (EOPS)
- 1 Final Declaration
That’s six submissions per year, not one.
TTAS ensures deadlines are tracked and submissions are made correctly.
6. Work With an MTD-Ready Accountant
MTD ITSA is not just a software change — it’s a process change.
An accountant helps you:
✔ Set up compliant systems
✔ Submit quarterly updates accurately
✔ Avoid penalties
✔ Plan tax payments better
✔ Reduce admin time
✔ Stay HMRC-compliant
At TTAS, we handle the technical side so you can focus on running your business.
