Best MTD Software for Sole Traders 2026: Free & Paid Options Compared

Making Tax Digital for Income Tax starts 6 April 2026. If you're a sole trader with gross income over £50,000, you need MTD-compatible software — not a nice-to-have, a legal requirement.

HMRC is sending notification letters to 860,000+ affected sole traders and landlords right now. If you've received one (or think you should have), this guide compares every MTD software option worth considering — from free HMRC tools to full accounting packages.

No affiliate links. No sponsored rankings. Just an honest comparison to help you pick the right tool and get compliant before the deadline.

What MTD ITSA Actually Requires

Before comparing software, let's be clear about what you're legally required to do from April 2026:

1. Keep digital records of all business income and expenses using MTD-compatible software
2. Submit quarterly updates to HMRC — four times per year, summarising your income and costs
3. Submit a final declaration at year-end (replacing your Self Assessment return)

You cannot submit quarterly updates through the HMRC website. It must go through HMRC-recognised MTD-compatible software. That's the whole point — and the whole reason you're reading this.

Who's affected from April 2026?

Gross income means total turnover before expenses. If your business turns over £55,000 but your profit is only £30,000 after costs, you're still caught by the £50k threshold.

For the full quarterly deadline calendar, see our MTD quarterly deadlines guide.

Quick Comparison: All 10 MTD Software Options

Here's the full picture at a glance. Scroll down for detailed reviews of each.

1. FreeAgent — Best Overall for UK Sole Traders

FreeAgent was built in Edinburgh specifically for UK small businesses, and it shows. The interface is designed around the UK tax system — Self Assessment, MTD, National Insurance, CIS — rather than being adapted from a US product.

What's Good

• MTD for Income Tax ready. Quarterly submissions and final declarations built in. No add-ons needed.
• Self Assessment filing. File your return directly from FreeAgent without touching HMRC's portal.
• Bank feeds. Connects to most UK banks. Auto-categorisation improves over time.
• Free with NatWest, Mettle, and Tide. If you bank with any of these, you get FreeAgent at no extra cost. That's a genuine £174/year saving.
• Mileage tracking. HMRC-approved mileage allowance calculations built in.
• Mobile app. Snap receipts, create invoices, check your tax position on the go.

What's Not Great

• Reporting is basic. If you want detailed P&L breakdowns or custom reports, it feels limited vs Xero.
• Invoice templates are functional but plain. They work, but won't win design awards. For better-looking invoices, use our free invoice generator alongside FreeAgent.
• No project tracking. Can't link expenses to specific clients or projects.

2. QuickBooks Self-Employed — Best Budget Option

QuickBooks Self-Employed is Intuit's entry-level product aimed squarely at sole traders. It's the cheapest paid option and does the basics competently — though it does feel slightly American at times.

What's Good

• Cheapest paid option. From £12/month — often discounted to £6/month for the first 6 months.
• Receipt scanning is excellent. The mobile app's OCR captures amount, date, and vendor automatically. Genuinely impressive.
• MTD ITSA compliant. Quarterly submissions and final declarations supported.
• Tax estimation. Shows your estimated tax bill throughout the year — useful for cash flow management.
• Bank feeds. Works with most UK banks.

What's Not Great

• Feels American. Built for the US market and adapted for the UK. Some terminology feels off.
• Invoicing is basic. Limited customisation. Use our invoice generator for better results.
• Smaller UK integration ecosystem compared to Xero.
• Support can be slow during tax season.

3. Xero — Best for Growing Businesses

Xero is the software your accountant wishes you'd use. It's the most powerful option on this list, with deep reporting, excellent multi-currency support, and an app ecosystem that connects to hundreds of other tools. But it's overkill for many sole traders.

What's Good

• Best invoicing. Clean templates, automatic reminders, online payment links, and read receipts so you can see when clients open your invoice.
• Robust reporting. Aged receivables, cash flow forecasts, budget vs actuals, custom P&L reports.
• Huge app marketplace. Stripe, PayPal, Shopify, project tools, CRMs — Xero integrates with everything.
• Multi-currency. If you invoice international clients, Xero handles exchange rates automatically.
• MTD ITSA compliant. Full quarterly submission support.
• Accountant collaboration. Your accountant gets their own login — no exporting needed.

What's Not Great

• Expensive for sole traders. The £17/month Starter plan limits you to 20 invoices/month. Most freelancers need the £32/month Standard plan.
• Learning curve. Designed for accountants first, sole traders second. Expect a few hours of setup.
• No built-in Self Assessment filing. You export data to file through HMRC or your accountant. FreeAgent wins here.

4. Sage Accounting — The Established UK Choice

Sage has been in UK accounting software for over 40 years. They're deeply embedded in the UK business ecosystem and have been working closely with HMRC on MTD compliance. Their sole trader product is solid if unexciting.

What's Good

• Strong UK pedigree. Built for the UK from day one. HMRC terminology, UK bank feeds, UK tax calculations — no American translations needed.
• MTD ITSA compliant. Quarterly updates and final declarations built in, with clear in-app guidance.
• Bank feeds and auto-categorisation. Works with most UK high street banks.
• Receipt capture. Mobile app with OCR scanning.
• Payroll available. If you hire subcontractors or have employees, Sage handles payroll without a separate add-on.

What's Not Great

• Interface feels dated. Functional but not as clean as FreeAgent or Xero.
• Pricing is confusing. Multiple tiers with overlapping features. Hard to know which plan you actually need.
• App marketplace is smaller than Xero's.
• Invoicing is fine but uninspired. Gets the job done without delighting anyone.

5. GoSimpleTax — Best for Tax Returns (Not Full Accounting)

GoSimpleTax takes a different approach. It's not accounting software — it's tax return software. It guides you through Self Assessment and MTD submissions step by step, with plain English explanations at every stage. Think TurboTax, but for the UK.

What's Good

• Free to calculate. You can enter all your figures and see your tax bill without paying. You only pay when you submit to HMRC — from around £50–£85 per return.
• MTD ITSA ready. Supports quarterly digital submissions and final declarations.
• Tax-saving suggestions. Highlights deductions you might be missing.
• Plain English guidance. Every box has an explanation. If you've always found tax returns confusing, GoSimpleTax makes them manageable.
• Per-return pricing. No monthly subscription — you pay once per year. Good for simple businesses that don't need ongoing accounting software.

What's Not Great

• Not accounting software. No bank feeds, no invoicing, no expense tracking throughout the year. You still need to keep your own records separately.
• No mobile app. Web-based only.
• You need organised records first. GoSimpleTax takes your figures and submits them — it doesn't help you organise them throughout the year.

6. Coconut — Best "Zero Admin" Option

Coconut combines a business current account with built-in bookkeeping. Every transaction in your Coconut account is automatically logged. No bank feeds to connect, no imports, no reconciliation — it's all one system.

What's Good

• Zero friction. Every transaction is automatically categorised for tax. The bookkeeping literally does itself.
• Tax pots. Automatically sets aside a percentage of each payment for your tax bill. Simple but genuinely useful for cash flow management.
• Free tier. Basic bookkeeping and categorisation at no cost.
• MTD compliant on the paid tier (£14/month), which adds invoicing and MTD submissions.
• Built for sole traders. Beautifully simple interface — no accounting jargon.

What's Not Great

• You have to switch your business bank account. That's a big commitment. If you're happy with your current bank, this is a hard sell.
• Limited features. No multi-currency, no project tracking, no time tracking.
• Smaller company. Less established than FreeAgent or Xero, which concerns some people when their money is involved.

7. Hammock — Best for Tax Forecasting

Hammock focuses on the thing freelancers worry about most: how much tax they'll owe. It connects to your bank and calculates your tax liability in real time, so there are no January surprises.

What's Good

• Real-time tax forecast. See your estimated Income Tax and National Insurance update as you earn and spend.
• Automatic tax savings. Set rules to move a percentage of income into a savings pot. Works with your existing bank — no account switching needed.
• Free plan is genuinely useful. Bank connection, tax forecast, and basic categorisation at no cost.
• MTD compliant on paid plans.

What's Not Great

• Invoicing is an afterthought. You'll want a separate tool for professional invoices.
• Limited expense categories. Power users will find it too simple.
• Relatively new. Feature set still growing.

8. Taxfix (formerly TaxScouts) — Best "Done For You" Service

Taxfix (rebranded from TaxScouts) isn't really software — it's a service. You get assigned a real accredited accountant who handles your MTD submissions and tax returns for you. They provide the MTD-compatible software as part of the package.

What's Good

• A real human does it for you. Upload your documents, answer some questions, and an accountant handles the rest — quarterly submissions, final declaration, everything.
• Fixed pricing. From around £169/year for sole traders. No hourly billing surprises.
• MTD software included. You don't need to choose or set up separate software.
• Good for the technophobic. If the idea of using accounting software fills you with dread, this removes that barrier entirely.

What's Not Great

• More expensive than DIY. You're paying for an accountant's time, not just software.
• Less control. You're trusting someone else with your financial records and submissions.
• No ongoing bookkeeping. They handle the tax submissions, but you still need to keep records throughout the year.
• No invoicing or expense tracking tools.

9. Bridging Software — Best for Spreadsheet Users

If you already track income and expenses in a spreadsheet and it's working for you, bridging software lets you keep your existing system and submit to HMRC digitally. It "bridges" the gap between your spreadsheet and HMRC's MTD API.

What's Good

• Keep your spreadsheet. No need to migrate years of data to new software or learn a new system.
• Cheap. Most bridging software costs £50–£150/year. Some free options exist for basic submissions.
• Simple. Enter your quarterly totals, click submit. That's it.
• Good for accountants. Many accountants use bridging software for clients who keep their own records.

What's Not Great

• No automation. No bank feeds, no receipt scanning, no auto-categorisation. You're still doing all the manual work.
• Error-prone. If your spreadsheet has mistakes, bridging software won't catch them — it just submits what you give it.
• No invoicing. You need a separate tool for creating invoices.
• HMRC may tighten rules. The government wants everyone on digital software eventually. Bridging may not be a long-term solution.

For a detailed comparison of bridging software options, see our MTD bridging software guide.

10. HMRC's Free MTD Tool — The Zero-Cost Option

HMRC offers a basic free tool for MTD submissions. It's exactly what you'd expect from a government product: it works, it's free, and it does the absolute minimum.

What's Good

• Completely free. No subscription, no per-return fee, no hidden costs.
• Officially from HMRC. No compatibility concerns — it's built by the people receiving your submissions.
• Good enough for very simple businesses. If you have one income source and straightforward expenses, it handles the quarterly submissions.

What's Not Great

• Extremely basic. No bank feeds, no invoicing, no receipt scanning, no expense tracking, no tax forecasting.
• No mobile app.
• Minimal guidance. It assumes you know what you're doing. No tax-saving suggestions or error checking.
• Clunky interface. It's a government website. Expectations should be calibrated accordingly.

Which MTD Software Should You Choose?

Here's the decision tree based on your situation:

The Real Costs: What You'll Actually Pay

Let's be honest about the total cost of MTD compliance, not just software subscriptions:

Remember: all MTD software costs are tax-deductible business expenses. A £174/year subscription actually costs you around £139 after tax relief (at the basic rate). For the full breakdown, see our real cost of MTD guide.

How Landolio's Free Tools Complement Any MTD Software

Whichever MTD software you choose, Landolio's free tools fill the gaps that most accounting software leaves:

• Invoice Generator — create professional UK invoices that meet HMRC requirements. Better-looking templates than most accounting software includes. The data still gets logged in your MTD software when you're paid.
• Late Payment Interest Calculator — work out statutory interest on overdue invoices. Essential when clients don't pay on time.
• Self-Assessment Tax Calculator — estimate your tax bill for 2025/26 before your software calculates it officially.
• Cash Flow Forecast — see what's coming in and going out, alongside your MTD software's bookkeeping.

These tools work alongside your MTD software, not instead of it. Use your MTD software for the legal compliance bits (record keeping, quarterly submissions), and Landolio's tools for the practical business bits (invoicing, payment chasing, cash flow).

Frequently Asked Questions

Can I use free MTD software and still be compliant?
Yes. HMRC's free tool, FreeAgent (free via NatWest/Mettle/Tide), Coconut's free tier, and Hammock's free tier all meet MTD requirements. Free doesn't mean non-compliant.

Do I still need an accountant with MTD software?
Not necessarily. MTD software handles the submissions for you. An accountant is still valuable for tax planning, but many sole traders manage MTD compliance themselves. If you want an accountant, Taxfix is the most cost-effective option.

Can my accountant submit on my behalf?
Yes. Your accountant can use their own MTD software to submit your quarterly updates and final declaration. Many are already set up for this.

What if I earn just under £50,000?
You're not mandated for April 2026 — but you will be from April 2027 (£30k threshold). Consider getting set up early so it's not a rush next year.

What about the penalties?
First year (2026/27) has a grace period — no penalty points for late quarterly submissions. From year two, late submissions earn penalty points. At 4 points, each subsequent late submission costs £200. Full breakdown in our MTD penalties guide.

Is MTD replacing Self Assessment?
Not exactly — the final declaration replaces your annual tax return, but the system is similar. We explain the differences in our MTD vs Self Assessment guide.

What records do I need to keep digitally?
Income (every sale/payment received), expenses (date, amount, category), and bank transactions. For the full list, see our quarterly updates guide.
