Best Free Accounting Software for UK Freelancers in 2026

Last updated: July 2026

Since April 2026, UK freelancers earning over £50,000 a year have been required to use HMRC-recognised software to submit quarterly income tax updates under Making Tax Digital for Income Tax (MTD ITSA). That makes choosing the right accounting software feel urgent — and potentially expensive. It doesn't have to be. There are five credible free accounting tools available to UK freelancers right now, and at least two of them handle MTD ITSA out of the box.

This guide reviews each option honestly: what you actually get on the free plan, what you'll have to upgrade to unlock, and which tool suits your specific situation. If your biggest worry is receipts piling up in a shoebox while you decide which software to use, that problem is easier to fix than the software question — a receipt capture tool running alongside your free accounting software costs less than a round of coffees a month.

Stop losing receipts. Dext captures every expense from a photo and feeds it straight into your accounting software — whichever one you choose.

FreeAgent: The best free option — if you use the right bank

FreeAgent is the most capable free accounting tool available to UK freelancers, but calling it "free" requires a small qualifier: you need to hold a qualifying business bank account with NatWest, RBS, Ulster Bank, or Mettle. If you do, FreeAgent's full product — including MTD ITSA quarterly submissions, self-assessment preparation, payroll, and project tracking — is included at no charge. The catch with Mettle specifically is that you must make at least one transaction per month from the account or billing can begin; this is worth knowing before you open the account and forget about it.

For freelancers who already bank with NatWest or RBS, this is the most obvious decision you'll make this year. For those who don't, Mettle is a free business current account with no monthly fee, no minimum balance requirement, and a straightforward mobile app. Opening one solely to unlock FreeAgent is entirely reasonable — many sole traders do exactly that. If you want the full picture on what you get, our detailed FreeAgent review covers every feature and a few limitations worth knowing about.

Paid tier: £19/month (excl. VAT) for sole traders if you're not banking with a qualifying account.

MTD ITSA: HMRC-recognised. FreeAgent has been one of the earliest and most reliable MTD implementations in the UK market.

Limitations: It's not a free product if you don't switch banks. The mobile app is functional rather than impressive. Receipt capture requires a separate tool — FreeAgent's built-in mobile receipt feature is basic.

Clear Books Sole Trader Free: MTD from day one

Clear Books is a UK-built accounting platform that launched a genuinely free-forever plan for sole traders — and unlike most "free" tiers, it includes MTD ITSA quarterly filing. The plan caps you at 5 invoices per month and 25 transactions per month, which makes it unsuitable for anyone running a busy practice, but for a freelancer just starting out with a handful of clients and modest transaction volumes, it covers the compliance essentials without touching your card details.

The transaction cap is the constraint that bites most quickly. Once you factor in bank feeds, supplier invoices, and expense entries, 25 transactions a month runs out faster than you'd expect. When that happens, Clear Books' paid plans start from around £10/month — reasonable by market standards, and the upgrade path is smooth.

MTD ITSA: Included on the free plan. This is the most notable thing about this tier — most tools that support MTD ITSA either charge for it directly or bundle it into mid-tier plans.

Best for: Freelancers in the first year of trading, part-time contractors with low transaction volumes, and anyone who wants to test MTD compliance before committing to a subscription.

Limitations: Five invoices a month is tight for active freelancers. Limited integrations on the free tier. Payroll not included.

Zoho Books: The most powerful free tier

Zoho Books' free plan is genuinely generous on features. You get double-entry bookkeeping, bank reconciliation, multi-currency invoicing, client portal access, and a solid mobile app — all without paying a penny. The free tier supports one user plus one accountant, which covers almost every sole trader situation. Invoice limits apply (check Zoho's current UK pricing page for exact figures, as these have changed without notice before).

The significant caveat for UK freelancers in 2026 is MTD ITSA. Zoho Books is HMRC-recognised for Making Tax Digital VAT, and MTD for Income Tax. Zoho Books is HMRC-recognised for both. The free plan includes MTD for Income Tax submissions, covering quarterly updates required from April 2026. If you're above the £50k threshold, the free tier supports quarterly filing directly. For more on which software is currently HMRC-approved for quarterly income tax filing, our MTD software guide covers the full approved list.

Data storage: Zoho offers EU data residency, which satisfies UK GDPR adequacy requirements post-Brexit. This matters for freelancers handling client financial data.

Best for: Freelancers below the MTD ITSA threshold who need strong invoicing features, multi-currency support, or client-facing portal functionality.

Limitations: MTD ITSA requires a paid plan. Zoho's product suite is large and the UI can feel complex for first-time users. Customer support response times can be slow on the free tier.

QuickFile: UK-built and free until you scale

QuickFile is one of the few accounting tools built specifically for the UK market from the ground up. It's free for accounts with up to 1,000 ledger entries per account year — which comfortably covers most freelancers with modest transaction volumes. Beyond that limit, the Power User plan costs £60+VAT per year (£72 inc. VAT), making it one of the cheapest paid accounting subscriptions available in the UK.

QuickFile has a strong following among UK accountants and bookkeepers, particularly those who work with smaller clients. If your accountant already uses QuickFile, there's a real practical benefit to having your books in the same system — it simplifies year-end work and reduces the back-and-forth.

MTD ITSA support is only available on the Power User plan. On the free tier, you can manage invoicing, bank reconciliation, and VAT returns (MTD VAT is supported), but quarterly income tax submissions for MTD ITSA require upgrading. At £72 a year, that's still significantly cheaper than most alternatives — worth factoring into a real cost comparison.

Best for: Freelancers whose accountant recommends QuickFile; those who want a UK-native tool with a long track record; lower-volume businesses happy to stay within the 1,000 entry free tier.

Limitations: The interface looks dated compared to modern cloud tools. Mobile app is functional but not polished. MTD ITSA costs extra.

Wave: Free, but not built for UK tax compliance

Wave is a Canadian product that offers free accounting and invoicing to UK users, and for basic bookkeeping records it works fine. The interface is clean, the double-entry accounting is sound, and there's no cost involved. However, Wave has zero MTD support — no MTD VAT, no MTD ITSA — and that is a significant problem for any UK freelancer using it as their primary compliance tool.

Wave stores data on US servers. That creates a compliance question under UK GDPR, particularly if your books contain any client-identifiable financial information. It's not an automatic violation, but it's a risk you'd need to assess. Wave's Pro plan exists but is priced in USD and not available for purchase in the UK.

The conclusion is practical: Wave is useful for freelancers who are below any MTD threshold and simply want to track income and expenses digitally rather than in a spreadsheet. As soon as MTD ITSA applies to you — currently earnings over £50,000, dropping to £30,000 from April 2027 — Wave cannot serve as your sole accounting tool. If you're not sure whether MTD affects you yet, our plain-English guide to Making Tax Digital explains the thresholds, deadlines, and what filing actually involves.

Best for: Freelancers below the MTD threshold who want the absolute simplest free option and aren't handling client financial data.

Limitations: No MTD support of any kind. US data servers. No UK customer support. Cannot be used as a standalone tool once MTD ITSA applies to you.

What most free tools miss: receipt capture

Every tool on this list handles invoicing and bank reconciliation. What none of them handle well — at least on free tiers — is the unglamorous daily job of capturing receipts, coding expenses, and feeding them into your ledger without manual data entry. That's where freelancers consistently make the kind of costly bookkeeping mistakes that either cost money at year-end or cause HMRC enquiry triggers.

Pairing any free accounting tool with a dedicated receipt capture tool like Dext is the standard approach among UK bookkeepers. Dext integrates with FreeAgent, Zoho Books, QuickFile, and most other cloud accounting tools, turning a photo of a receipt into a categorised, tax-ready transaction in seconds. At around £15–£20/month, it's not free — but it removes the most error-prone part of the bookkeeping workflow. If you want to see how a full low-cost stack fits together, our guide to the complete AI bookkeeping stack under £60/month shows exactly what a productive setup looks like.

Which free tool is right for you?

You already bank with NatWest, RBS, or Ulster Bank: Use FreeAgent. There's no better free accounting software available to UK freelancers. Full stop.

You're willing to open a second bank account: Open Mettle (takes 10 minutes, no fees), make one transaction a month, and get FreeAgent free. This is the best-value move available.

You're brand new and have fewer than 5 clients: Start with Clear Books' free plan. You get MTD ITSA compliance included, and you can upgrade when you outgrow it.

You have overseas clients or complex invoicing needs: Zoho Books' free tier is the most feature-rich option for invoicing and multi-currency work — just be aware you'll need to supplement or upgrade when MTD ITSA kicks in.

Your accountant uses QuickFile: Match your accountant's system. The free tier covers most small freelancers, and the £72/year upgrade to Power User (which includes MTD ITSA) is one of the cheapest routes to full compliance.

You earn under £30,000 and just want simple records: Wave works for basic bookkeeping, but plan your exit — the MTD ITSA threshold drops to £30k from April 2027, and migrating data between accounting platforms mid-year is painful. Better to start on a compliant tool now.

Frequently asked questions

Is free accounting software really good enough for UK tax returns?

For MTD ITSA quarterly updates, you need HMRC-recognised software regardless of cost. FreeAgent and Clear Books' free plans are both HMRC-recognised. Wave is not. Whether a tool is free has no bearing on whether it's compliant — what matters is whether it's on HMRC's approved software list.

Will I need to pay for accounting software once Making Tax Digital expands?

Not necessarily. FreeAgent (with a qualifying bank account) and Clear Books' free plan both support MTD ITSA today. As the income threshold drops from £50,000 to £30,000 in April 2027, more freelancers will need compliant software — but compliant doesn't mean paid.

Can I start on a free tool and switch later?

Yes, but plan for migration costs. Exporting data from one system and importing it into another takes time and sometimes money. The safest approach is to choose a tool you'd be happy upgrading within — so if you outgrow Clear Books' free tier, you upgrade within Clear Books rather than starting fresh in Xero.

What about spreadsheets? Can I just use Excel for now?

For MTD ITSA, you'll need bridging software to submit from a spreadsheet — there's no direct spreadsheet-to-HMRC submission route. Bridging software costs money. A free accounting tool with native MTD ITSA support is almost certainly the simpler and cheaper option than bridging spreadsheets.

Is the Mettle/FreeAgent offer likely to change?

FreeAgent is owned by NatWest Group, so the bank-account-linked free offer is structurally embedded in their product strategy. There's no indication it's being withdrawn, but it's worth confirming terms on the FreeAgent website before basing your setup on it.
