Best Accounting Software for UK Sole Traders (2026): Xero, FreeAgent, QuickBooks, Sage and Zoho Compared

Making Tax Digital for Income Tax is now live. From April 2026, sole traders and landlords earning above £50,000 must keep digital records and submit quarterly updates to HMRC — and that threshold drops to £30,000 in April 2027, then to £20,000 in April 2028. If you are still running your books in a spreadsheet, you are on borrowed time.

At the same time, the software market has shifted. Xero is raising its UK prices on 1 September 2026. QuickBooks pushed through a 47% increase on its Plus plan in January. Zoho Books quietly added Self Assessment filing to its free tier in July. The best tool for a UK sole trader in 2026 is not the same answer it was twelve months ago — and it is certainly not the same as the answer for a limited company or a practice with twenty clients.

This guide cuts through the marketing copy. Five tools. Current UK pricing (including the upcoming Xero increase). Honest pros, cons, and MTD ITSA status for each. A clear verdict on who each suits.

⚠️ Xero UK prices rise 1 September 2026 — Ignite goes from £16 to £18/mo. If you're considering Xero, locking in now saves £24/year on the Ignite plan.

TL;DR — three things to know

• FreeAgent is free if you bank with NatWest, RBS, or Mettle. For most sole traders, that settles the question immediately.
• QuickBooks Sole Trader Plus (£10/mo) is the cheapest MTD ITSA-compliant option for non-VAT-registered sole traders.
• Xero Ignite (£18/mo from 1 September) is the best choice if you work with an accountant or need room to grow beyond sole trader basics.

FreeAgent — Best for Most UK Sole Traders

What it is

FreeAgent was built specifically for UK freelancers and sole traders — not retrofitted from a platform designed for larger businesses. It handles invoicing, expense categorisation, bank feeds, Self Assessment filing, VAT returns, and MTD ITSA quarterly submissions from a single interface. NatWest Group acquired FreeAgent in 2018 and now offers it free to qualifying business banking customers.

UK Pricing

• Free — for active NatWest, RBS, Ulster Bank, or Mettle business banking customers. This covers the full feature set, not a stripped-down tier.
• £19/month + VAT — standalone subscription (or £190/year). Monthly price is on the high side versus alternatives without the bank tie-in.
• £10/month + VAT — Landlord plan (new in 2026, for single-property landlords).
• 30-day free trial available for standalone subscribers.

The maths is straightforward: if you already bank with NatWest, RBS, or Mettle, FreeAgent is free. Over three years that saves roughly £750 compared to Xero on the Ignite plan. If you don't bank with those institutions, £19/month is harder to justify when QuickBooks Sole Trader Plus achieves the same MTD compliance at £10/month.

Key Features for Sole Traders

• HMRC-recognised for both MTD VAT and MTD ITSA quarterly submissions
• Built-in Self Assessment (SA100) filing — no separate HMRC authorisation flow required beyond initial setup
• Real-time tax estimates update as you record income and expenses
• Time tracking and project management included
• Smart Capture for receipts: 10 per month on standard plan, unlimited for £5/month
• Handles both self-employment income and rental income in one account

Limitations

• Receipt capture is limited to 10 files/month on the standard plan — active traders will want to add Dext or Receipt Bot alongside for volume document capture
• Fewer integrations than Xero — around 100 third-party apps versus Xero's 1,000+
• Interface is functional but not the most modern-looking in the category
• The £19/month standalone price is steep relative to the competition

Best For

Sole traders and freelancers who bank with NatWest, RBS, or Mettle — this is the clearest win in the comparison. Also well-suited to anyone who wants native Self Assessment filing without a separate accountant or product, and landlords who have self-employment income alongside property rental.

QuickBooks — Best Budget Option for MTD ITSA

What it is

QuickBooks' UK sole trader offering was renamed and restructured in late 2024. The current Sole Trader Plus plan (£10/month) is the lowest-priced mainstream MTD ITSA-compliant product on the market, making it the default recommendation for non-VAT-registered sole traders who don't qualify for free FreeAgent. The next rung up — Simple Start at £16/month — adds VAT return filing, making it the minimum viable plan for anyone on the VAT register.

UK Pricing

• Sole Trader Plus: £10/month + VAT — MTD ITSA, invoicing, expense tracking, mileage. No VAT return filing. 90% off for first 6 months for new customers (introductory offer).
• Simple Start: £16/month + VAT — Everything above plus MTD VAT filing. Single user only. Read our QuickBooks Simple Start review for the full breakdown.
• Essentials: £38/month + VAT — Adds supplier bills (accounts payable), multi-currency, time tracking, up to 3 users.
• Plus: £50/month + VAT — Stock tracking, project costing, budgets, up to 5 users.

QuickBooks raised its prices significantly in January 2026 — Simple Start went from £12/month to £16/month, and Essentials jumped 58% from £24/month to £38/month. The Sole Trader Plus plan (launched late 2024) is the exception, sitting at £10/month and offering genuine value for straightforward MTD ITSA compliance.

Key Features for Sole Traders

• HMRC-recognised for MTD ITSA (all plans) and MTD VAT (Simple Start and above)
• Best-in-class mobile app for expense capture and mileage tracking
• Intuit Assist AI features: automatic transaction categorisation, anomaly detection, deeper financial context — available from Simple Start
• Strong quarterly update workflow — the MTD ITSA submission process is clear and guided
• Self Assessment filing included (guides you through the SA100 within the platform)
• 90% first-six-months offer is one of the better introductory deals in the category

Limitations

• The 90% introductory offer and the 30-day free trial are mutually exclusive — you must choose one at sign-up. If you plan to subscribe long-term, the promo is considerably cheaper.
• Sole Trader Plus does not include VAT return submission — a significant gap for any VAT-registered business, where Simple Start at £16/month is the minimum
• Simple Start is single-user only — if your bookkeeper or accountant needs access, you're looking at Essentials (£38/month)
• The large price gap between Simple Start (£16/month) and Essentials (£38/month) is a real pain point as businesses grow

Best For

Non-VAT-registered sole traders who want the cheapest credible MTD ITSA solution and value a strong mobile experience. Also suitable for trades where mileage tracking and mobile expense capture matter day-to-day — plumbers, electricians, consultants working away from a desk.

Xero — Best for Growth and Accountant Collaboration

What it is

Xero is the dominant cloud accounting platform in the UK and the tool most accountants and bookkeeping practices run their clients on. For sole traders, that has one major implication: if your accountant uses Xero, working in the same system removes a significant amount of friction from the client relationship. The trade-off is cost — Xero's Ignite plan is not cheap for a one-person business, and it is about to get pricier.

UK Pricing (Current and from 1 September 2026)

All prices exclude VAT. The price change applies to new and existing UK subscribers from 1 September 2026 — being an existing customer does not lock in your current rate. New customers can currently get 80% off for the first 6 months (reducing Ignite to around £3.20/month for that initial period), or take one month free. If you are actively considering Xero, signing up before September saves £24 per year on the Ignite plan and £24 on Grow.

The Simple plan at £7/month is worth noting separately. It is designed for sole traders primarily needing MTD ITSA compliance with very basic invoicing — it is not a full accounting product. Most sole traders with more than a handful of regular clients will need Ignite as their starting point. For a detailed breakdown of the Ignite vs Grow decision, see our Xero Ignite vs Grow comparison.

Key Features for Sole Traders

• HMRC-recognised for MTD ITSA and MTD VAT on all plans from Ignite
• Over 1,000 third-party integrations — the widest ecosystem in this comparison
• Xero Smart Document Capture (JAX-powered) on Ignite and above — AI receipt and invoice OCR directly inside Xero
• Strong bank feed network — connects to most major UK banks
• Multi-currency from Grow onwards
• Payroll add-on available (£1.50/employee/month for basic, included from Grow)
• Ignite includes basic bills (up to 10/month) — a meaningful difference from QuickBooks Simple Start

Limitations

• Ignite plan caps you at 20 invoices and 10 bills per month — any busy sole trader who invoices multiple clients regularly will hit this ceiling
• Bank reconciliation is an optional £3.50/month add-on on Ignite; included from Grow
• Xero does not include native Self Assessment filing — you submit quarterly MTD updates but still need an accountant or separate software for the Final SA100 declaration
• The jump from Ignite (£18/month) to Grow (£39/month) is steep for what amounts to unlimited invoice volume and included payroll
• Cost is higher than FreeAgent's free tier and QuickBooks Sole Trader at £10/month

Best For

Sole traders who work with an accountant already using Xero, those who expect to grow and want a platform that scales without migration, and businesses that need a wide range of app integrations. Also the natural choice for anyone wanting Smart Document Capture built directly into their accounting workflow rather than as a separate product.

Sage — Best for Businesses with Employees or CIS

What it is

Sage is a Newcastle-headquartered company with deep roots in UK accounting. Its cloud offering, Sage Accounting, is a capable platform — but it is primarily designed for small businesses with employees rather than pure sole traders. For a one-person business with straightforward income and expenses, Sage is more software than you need at a price that is hard to justify against the alternatives.

UK Pricing

• Accounting Start: ~£12–14/month + VAT — Basic invoicing, expense tracking, bank reconciliation. Note: MTD ITSA quarterly submission is on the Standard plan, not Start. Check Sage's current pricing page carefully before signing up, as promotional rates vary.
• Accounting Standard: ~£25–28/month + VAT — Full MTD VAT and MTD ITSA submissions, cash flow forecasting, customisable reporting.
• Accounting Plus: ~£36–40/month + VAT — Adds multi-currency, advanced inventory, budget tracking.
• Promotional offer: 90% off for the first 6 months is common, reducing the Standard plan to under £3/month initially.
• Payroll is a separate add-on starting from around £7/month.

The pricing picture with Sage is complicated by the fact that the entry-level Start plan is not fully MTD ITSA compliant for quarterly Income Tax submissions — you typically need Standard for that. This makes the effective entry price for a compliant sole trader solution closer to £25–28/month, which is higher than Xero Ignite at £18/month from September.

Key Features for Sole Traders

• HMRC-recognised for MTD VAT and MTD ITSA on the Standard plan
• Payroll included in higher tiers — significant if you have one or two employees
• Strong CIS workflow — best in class for construction industry workers
• Cash flow forecasting on Standard and above
• UK-based support with a 30-year heritage in UK accounting

Limitations

• You need Standard (£25–28/month) for full MTD ITSA compliance — the Start plan is not sufficient for quarterly digital submission
• More expensive than FreeAgent (free with qualifying bank), QuickBooks Sole Trader Plus (£10/month), or Xero Ignite (£18/month) for the same MTD ITSA coverage
• Around 150 third-party app integrations versus Xero's 1,000+
• Less intuitive interface for non-accountants compared to FreeAgent or QuickBooks

Best For

CIS contractors in construction, sole traders with one or two employees who want payroll built in from the start, and businesses with existing Sage relationships. If you are in the construction industry and deal with the Construction Industry Scheme, Sage's CIS workflow is the strongest in this comparison. For a full three-way head-to-head, see our Sage vs Xero vs QuickBooks comparison.

Zoho Books — Best Free Option for Budget-Conscious Sole Traders

What it is

Zoho Books is consistently the most underrated tool in the UK sole trader accounting market. The free tier covers invoicing, bank feeds, expense tracking, MTD VAT, and — following a July 2026 update — Self Assessment (SA100) filing as well. Up to 1,000 invoices per year, which covers the majority of UK sole traders without a plan upgrade. The catch: Zoho is an Indian company, and its UK-specific accounting knowledge can feel thinner than FreeAgent or Xero.

UK Pricing

• Free — up to 1,000 invoices/year, 1 user, bank feeds, MTD VAT, MTD ITSA, and SA100 filing (added July 2026). This is a genuine functional free tier, not a trial.
• Standard: ~£10/month + VAT (billed annually) — removes the invoice cap, adds recurring invoices, more users, more bank accounts. The most popular paid tier for sole traders who grow beyond the free limits.
• Professional and above — inventory management, project tracking, custom domains, Zoho CRM integration.
• 14-day free trial on paid plans.

Key Features for Sole Traders

• HMRC-recognised for MTD VAT and MTD ITSA — both included on the free plan
• SA100 Self Assessment filing added to the free plan in July 2026 — making it the most complete free option by a distance
• Strong invoice customisation and professional invoice templates
• Bank feeds and automated reconciliation on free plan
• Part of the wider Zoho ecosystem — integrates with Zoho CRM, Zoho Projects, etc. if you use other Zoho products

Limitations

• The 1,000-invoice-per-year limit is generous for most sole traders but imposes a hard ceiling — busy tradespeople who invoice daily will hit it
• UK-specific accounting knowledge is less deep than FreeAgent or Xero — some UK-specific workflows require workarounds
• Support response times can be slower than Xero or QuickBooks
• The wider Zoho interface can feel overwhelming if you are only using Zoho Books in isolation
• Less familiar to UK accountants than FreeAgent, Xero, or QuickBooks — collaborative workflows can be clunky

Best For

Sole traders who want a genuine free MTD-compliant accounting solution and do not need their accountant to work directly inside the platform. Read our Zoho Books UK review for a detailed assessment — including how the July 2026 SA100 update changes the value calculation significantly.

Which Tool Should You Choose? A Decision Framework

The right answer depends on four questions. Work through them in order:

1. Do you bank with NatWest, RBS, Ulster Bank, or Mettle? If yes, use FreeAgent. It is free, it is comprehensive, and the bank connection is seamless. There is no meaningful argument for paying another platform £10–18/month when FreeAgent is available at no cost.
2. Are you VAT-registered? If yes, QuickBooks Sole Trader Plus (£10/month) does not cover you — you need Simple Start (£16/month), FreeAgent (£19/month), or Xero Ignite (£18/month). If no, QuickBooks Sole Trader Plus at £10/month covers everything you need for MTD ITSA and is the cheapest compliant option.
3. Does your accountant use Xero? If yes, match their platform. The collaboration value — shared bank feeds, real-time visibility, reduced accountant time — typically outweighs the cost difference.
4. Do you need to keep software costs to zero? Zoho Books' free tier is now the only genuinely free MTD ITSA-compliant option that also includes SA100 filing. As long as you are under 1,000 invoices per year, it covers everything.

If none of the above produce a clear answer, the default recommendation for a non-VAT, sole trader without a Xero accountant and without NatWest banking is: QuickBooks Sole Trader Plus at £10/month. It is the cheapest mainstream MTD ITSA solution, it has a strong mobile app, and the 90% introductory offer makes the first six months very low risk.

What About Receipt Capture?

Every accounting package in this comparison handles basic receipt and invoice input, but none of them are purpose-built for high-volume document capture. If you are processing more than 30–50 receipts or supplier invoices per month, it is worth adding a dedicated receipt capture tool to your stack. These automatically extract line-item data via OCR, sync to your accounting software, and dramatically reduce manual data entry.

The two HMRC-approved tools with affiliate programmes we use are Dext (market leader, strongest accuracy, used by most UK bookkeeping practices) and Receipt Bot (budget-friendly alternative, 20% of Dext's price, still HMRC-compliant). Our receipt capture comparison covers both in detail.

If you use the complete AI bookkeeping stack approach — accounting software plus receipt capture plus MTD submission — you can keep the entire operation under £30/month for most sole traders, with near-zero manual data entry.

The Right Pick For...

• A freelance consultant earning £55,000+ who banks with NatWest: FreeAgent free. Done.
• A plumber or electrician who is non-VAT, self-employed: QuickBooks Sole Trader Plus at £10/month. Strong mobile app, mileage tracking, MTD ITSA — exactly what the work requires.
• A VAT-registered sole trader whose accountant uses Xero: Xero Ignite at £18/month from September. Sign up before 1 September to lock in the current £16/month rate.
• A sole trader on a very tight budget who wants free MTD: Zoho Books free tier. Since July 2026 this also covers SA100 filing — the complete package at no cost.
• A CIS contractor in construction: Sage Accounting Standard (~£25–28/month). Best CIS workflow in this comparison; payroll support if you have occasional subbies.
• A growing sole trader approaching the VAT threshold, working with an accountant: Xero Ignite. The ecosystem, the collaboration tools, and the scalability justify the cost relative to the alternatives.

Frequently Asked Questions

Do I actually need accounting software now for MTD ITSA?

If your gross self-employment or rental income exceeded £50,000 in the 2025/26 tax year, yes — you must use HMRC-recognised software for quarterly updates from April 2026. The threshold drops to £30,000 for 2026/27 and £20,000 for 2027/28. During the 2026/27 tax year there is a soft landing: HMRC will not issue penalty points for missed quarterly update filings. But the habit needs to be established now, before penalties kick in. See our complete MTD guide and the soft landing explainer for detail on what is and is not protected this year.

Can I switch accounting software mid-year without losing data?

Yes, but it requires care. You need to export your chart of accounts, opening balances, customer and supplier records, and transaction history before migrating. The best time to switch is at the start of a new tax year (6 April) or at the end of a VAT quarter. See our MTD software guide for a switching checklist.

Is QuickBooks Sole Trader Plus the same as QuickBooks Self-Employed?

No. QuickBooks Self-Employed was the old product — it was primarily a tax calculation tool and could not submit quarterly MTD ITSA updates directly. Sole Trader Plus replaced it in late 2024 and is a full MTD ITSA-compliant product. If you are on an old Self-Employed subscription, check your plan status in the QuickBooks dashboard — you may need to migrate.

Does Xero Simple plan include MTD ITSA?

Yes, the Xero Simple plan (£7/month, no price rise from September) is on HMRC's recognised software list for MTD ITSA. However, it is very restricted — basic income and expense recording, very limited invoicing. Most active sole traders will find it insufficient and should consider Ignite as the practical entry point.

What happens if I miss a quarterly MTD update?

Under the soft landing rules in 2026/27, HMRC will not issue penalty points for missed quarterly update filings during this transition year. From 2027/28, the points-based system applies: each missed quarterly update earns one penalty point, and once you reach the threshold (four points for quarterly filers), a £200 penalty is triggered. The MTD-ready vs HMRC-recognised guide explains the difference between software that claims compliance and software that is actually on the recognised list.
