Best Accounting Software UK Sole Traders 2026

With Making Tax Digital for Income Tax starting in April 2026, most UK freelancers and sole traders will eventually need MTD-compatible accounting software. Even if you're not in the first wave yet, choosing the right software now means you build the right habits before the deadline applies to you. Not sure if MTD applies to you yet? Check whether you're affected.

This comparison covers the four main options for UK sole traders: FreeAgent, Xero, QuickBooks, and Sage. We've looked at UK pricing, MTD compatibility, ease of use for one-person businesses, and what's actually different between them — not just the marketing copy. Not sure which software type is right for you? Our MTD software chooser can help narrow it down.

Quick Comparison

	Best for	Price from	MTD-ready
FreeAgent	Most UK freelancers	Free (with qualifying bank)	Yes
Xero	Growing businesses and limited companies	£7/month	Yes
QuickBooks	Mobile expense capture and mileage	£12/month	Yes
Sage	Established businesses or accountant-led setups	£15/month	Yes

FreeAgent — Best Accounting Software for Most UK Freelancers

Price: £29/month (50% off for first 6 months). Free with NatWest, RBS, Ulster Bank, or Mettle business accounts.

FreeAgent was built specifically for sole traders, freelancers, and contractors — and it shows. The interface assumes you're running a one-person service business, not managing a warehouse. It handles:

• Self Assessment filing directly to HMRC (including all income sources)
• MTD for VAT and MTD for Income Tax (ITSA)
• Invoice creation and tracking
• Expense categorisation using HMRC's actual categories
• Tax estimate calculator — shows you what you'll owe in real time
• Project and time tracking

The biggest differentiator is free access via NatWest, RBS, Ulster Bank, and Mettle. If you already bank with one of these — or are open to switching — FreeAgent costs you nothing. This makes it by far the best value option for most UK freelancers. Read our full FreeAgent review for a detailed breakdown.

What FreeAgent doesn't do well: it's less capable if you have staff, manage inventory, or need advanced financial reporting. For a growing limited company, Xero is likely a better fit.

MTD status: Fully compatible with MTD for VAT and MTD for ITSA. HMRC-recognised.

Xero — Best for Growing Freelancers and Limited Companies

Price: £7/month (Starter), £27/month (Standard), £65/month (Premium) — prices from September 2025.

Xero is the market leader in UK small business accounting software, and it earns that position through depth of features and integrations. For a sole trader, the Starter plan is usually sufficient — it covers invoicing, bank reconciliation, and MTD filing.

Key strengths:

• Excellent integrations with payment processors, apps, and banks
• Strong VAT handling and MTD compliance
• Good reporting — better than FreeAgent for visualising your financial position
• Payroll add-on available (useful if you ever employ someone)
• 24/7 online support

What Xero doesn't do as well: it's noticeably more complex than FreeAgent for a pure sole trader. The interface assumes more accounting knowledge. Self Assessment filing requires more steps. For a designer or consultant who just wants to send invoices and know their tax estimate, FreeAgent is simpler. See our Xero review for a full feature and pricing breakdown.

MTD status: Fully MTD-compliant for VAT and ITSA. HMRC-recognised.

QuickBooks — Best Mobile Experience

Price: £12/month (Simple Start), £25/month (Essentials), £35/month (Plus) — prices as of late 2025.

QuickBooks has the best mobile app of the four — if you capture expenses on the go using your phone, QuickBooks makes this particularly smooth. It's also very strong on mileage tracking (useful for trades and photographers) and integrates well with PayPal and Stripe.

Key strengths:

• Best-in-class mobile app
• Strong receipt capture via phone camera
• Mileage tracking built in
• UK-based phone support (the only one of the four with this)
• MTD-ready

What QuickBooks doesn't do as well: it's more expensive than FreeAgent and Xero Starter for equivalent functionality. Self Assessment support is less seamless than FreeAgent. Some UK-specific features lag behind FreeAgent. Our QuickBooks review covers the full picture.

MTD status: Fully MTD-compliant. HMRC-recognised.

Sage — Best for Established Small Businesses

Price: Various plans; Accounting Start from approximately £15/month.

Sage is a well-established UK brand and a perfectly capable accounting tool. For sole traders, it's generally not the first recommendation — the interface is more complex than FreeAgent or QuickBooks, and the pricing isn't as competitive for basic use cases.

Sage makes more sense if you're already familiar with it, if your accountant uses it (so they can access your data directly), or if you're a growing business that needs Sage's more advanced features. Read our Sage review for a detailed look at what's included at each tier.

MTD status: Fully MTD-compliant. HMRC-recognised.

The Free Option: HMRC's Own Service

HMRC offers a free digital service for MTD submissions, but it's basic — suitable for very simple situations (one income stream, no employees, straightforward expenses). Most freelancers with any complexity to their finances will find it inadequate. It's worth knowing it exists, but it shouldn't be your first choice.

Which Accounting Software Should You Choose?

For most UK freelancers and sole traders, the decision comes down to:

• Choose FreeAgent if you bank with NatWest, RBS, Ulster Bank, or Mettle (it's free). Or if you want the simplest, most UK-native option with seamless Self Assessment filing.
• Choose Xero if you're running a limited company, have multiple income streams, need strong integrations, or want to scale.
• Choose QuickBooks if you capture a lot of mobile expenses, track mileage regularly, or prefer phone-based customer support.
• Choose Sage if you're already on Sage, or your accountant specifically recommends it for compatibility.

If you're unsure, our Xero vs FreeAgent comparison covers the two most popular options side by side.

Our recommendation for most UK freelancers: FreeAgent — particularly if you're able to switch to a bank account that includes it for free. It's the most UK-tailored option, handles Self Assessment better than the others, and the tax estimate feature is genuinely useful for knowing how much to set aside each month.

What About IR35?

None of the software above handles IR35 determination — that requires a separate assessment (using HMRC's CEST tool or an accountant). However, if you're a limited company contractor dealing with IR35, that changes the software recommendation — Xero or QuickBooks are better suited to limited company accounting than FreeAgent.
