How to Choose MTD Software as a Sole Trader
Choosing MTD software is one of the most important decisions you will make for your business in 2026. The right software saves you time, reduces errors, and makes tax compliance almost effortless. The wrong choice creates frustration and extra work. Here is how to choose wisely.
Start with HMRC Compatibility
This is non-negotiable. Your software must be on HMRC's official list of MTD-compatible software for Income Tax. Not all accounting software supports MTD ITSA — some only handle MTD for VAT.
Check HMRC's list on GOV.UK before committing to any software. If it is not on the list, it cannot submit your quarterly updates to HMRC.
The Features That Actually Matter
Bank Feeds
The single most valuable feature in any MTD software is automatic bank feeds. When your business bank account is connected, transactions are imported without any manual effort. This alone can save you hours each month.
Check that the software supports your specific bank. Most major UK banks are covered, but some smaller banks or building societies may not be.
AI Categorisation
Modern MTD software uses artificial intelligence to categorise your transactions automatically. Instead of manually deciding whether each purchase is "office supplies" or "travel" or "professional fees", the AI suggests a category based on the merchant, amount, and your history.
This is a significant time-saver and reduces errors. Accounted uses Penny, an AI bookkeeper that learns your patterns and categorises with over 95% accuracy.
Receipt Capture
Being able to photograph a receipt and have it stored digitally, matched to the right transaction, and used as supporting evidence is enormously helpful. Look for software that offers receipt capture via a mobile app or — even better — WhatsApp.
Real-Time Tax Estimates
Good MTD software shows you an estimated tax bill at any point during the year. This helps you budget and avoids the shock of a large tax bill in January.
Automatic Submissions
Some software prepares and submits your quarterly updates automatically (with your confirmation). Others require you to manually navigate to a submission screen and trigger the process. Automatic is better.
Accountant Access
If you work with an accountant, look for software that allows them to access your records, review your figures, and manage submissions on your behalf.
Features That Are Less Important Than You Think
Invoicing. If you send invoices, an invoicing feature is convenient but not essential. Many sole traders use separate invoicing tools and that works fine.
Payroll. Unless you have employees, you do not need payroll functionality.
Inventory management. Most sole traders do not carry significant stock. If you do, this is important; otherwise, skip it.
Multi-currency support. Unless you regularly transact in foreign currencies, this adds complexity you do not need.
Pricing Considerations
MTD software pricing varies widely:
- Free options exist but typically have limitations — restricted transactions, no bank feeds, limited support
- Budget options (under £10/month) cover the basics but may lack AI features or receipt capture
- Mid-range (£10–£25/month) typically includes bank feeds, categorisation, receipt capture, and quarterly submissions
- Premium (over £25/month) adds advanced features like tax planning, multi-business support, or dedicated accountant portals
Consider the total cost of ownership, not just the subscription fee. Software that costs £15/month but saves you 5 hours of bookkeeping per month is far cheaper than free software that requires 10 hours of manual work.
Questions to Ask Before Choosing
- Is it on HMRC's MTD ITSA compatible list?
- Does it connect to my bank?
- How does it handle expense categorisation?
- Can I capture receipts from my phone?
- Does it show real-time tax estimates?
- Can my accountant access it?
- What happens to my data if I switch software later?
- Is there UK-based support?
- How long has the company been in business?
- What do other sole traders say about it?
Try Before You Commit
Most MTD software offers a free trial — typically 14 to 30 days. Use this period to:
- Connect your bank account and see if transactions import correctly
- Enter a few expenses and test the categorisation
- Explore the reporting and tax estimate features
- Check how easy it is to navigate and use day-to-day
Do not choose based on marketing alone. The software that looks best on a website may not be the most practical to use daily.
