Best Bookkeeping Apps for Self-Employed UK 2026

Being self-employed in the UK means wearing every hat — marketer, salesperson, project manager, and reluctant bookkeeper. The bookkeeping part is nobody's favourite, but it is the one that can land you in trouble with HMRC if you get it wrong.

The good news is that bookkeeping apps have improved dramatically. The bad news is that there are dozens of them, and working out which one actually suits a self-employed person (rather than a ten-person company with an accountant on speed dial) takes more research than it should.

We have done that research. Here is an honest guide to the best bookkeeping apps for self-employed people in the UK in 2026, based on what matters to someone who works for themselves.

What Self-Employed People Actually Need

Before comparing apps, it helps to be specific about what "self-employed" means in this context. We are talking about sole traders, freelancers, and anyone who files a Self Assessment tax return as their primary or secondary income source. Not limited company directors — they have different needs.

As a self-employed person, you need:

• Automatic bank transaction imports — You should not be typing in transactions manually. Open Banking means your app can pull them in from your bank account automatically.
• Expense categorisation — HMRC requires your expenses to be in specific categories for Self Assessment. Your app should handle this, ideally without you needing to know what the categories are.
• Receipt capture and storage — HMRC requires you to keep records for five years. Photographing receipts and linking them to transactions is the simplest way to stay compliant.
• Tax estimates — Knowing what you owe throughout the year prevents nasty surprises in January. Your app should calculate Income Tax, National Insurance (Class 2 and Class 4), and payments on account.
• MTD quarterly submissions — If you earn over £50,000, Making Tax Digital is already live. If you earn over £30,000, it starts in April 2027. Your app must be HMRC-recognised for MTD.
• Self Assessment filing — Filing directly from your bookkeeping app saves you re-entering all your figures on the HMRC website.
• Mobile access — You are probably not sitting at a desk all day. Your bookkeeping app needs to work on your phone.

The Best Bookkeeping Apps Compared

1. Accounted — Best for Hands-Off Bookkeeping

Price: From £12/month | MTD: Yes | Self Assessment filing: Yes

Accounted was designed specifically for self-employed UK workers, and it shows. The standout feature is Penny, your AI bookkeeper, who categorises transactions automatically using a three-tier reasoning system that learns how your specific business works. When Penny is confident about a categorisation, it happens without your input. When confidence is lower, you get a simple prompt to confirm.

The WhatsApp integration is genuinely useful. Photograph a receipt, send it to Penny on WhatsApp, and the AI extracts all the details, categorises the expense, and matches it to your bank transaction. You do not need to download a separate app or learn a new interface.

Your tax estimate updates in real time as transactions are categorised, so you always know roughly what you owe. When Self Assessment time comes, your return is essentially pre-populated from a year of automated bookkeeping.

Where it excels: Automation, WhatsApp receipt scanning, UK-specific tax calculations, MTD-native design Where it could improve: No invoicing yet, UK only, newer to market

2. FreeAgent — Best Free Option (With NatWest)

Price: £14.50/month (free with NatWest/RBS) | MTD: Yes | Self Assessment filing: Yes

If you bank with NatWest, RBS, or Ulster Bank, FreeAgent is free — and it is genuinely good software, not a stripped-down freebie. You get bank feeds, invoicing, expense tracking, project management, and Self Assessment filing all included.

FreeAgent handles multiple income sources well, which is important if you are self-employed alongside employment or have rental income. The tax timeline gives you a clear visual of what you owe and when.

The limitation for self-employed users is that FreeAgent still expects a fair amount of manual work. You categorise transactions yourself, and the interface, while cleaner than some competitors, assumes a certain level of accounting knowledge.

Where it excels: Free with NatWest, full-featured, good tax timeline, Self Assessment filing Where it could improve: Manual categorisation, interface feels dated, limited automation

We compare these two in detail in our Accounted vs FreeAgent review.

3. QuickBooks Self-Employed — Best Budget Option

Price: From £12/month | MTD: Yes | Self Assessment filing: Yes (higher plans)

QuickBooks Self-Employed is a separate product from the main QuickBooks line, built specifically for freelancers and sole traders. It handles income and expense tracking, mileage logging, and basic tax estimates at a reasonable price.

The mobile app is polished and works well for quick expense entry and receipt capture. The automatic categorisation is basic but functional — it learns from your corrections over time, though not as quickly or accurately as AI-powered alternatives.

The challenge is that QuickBooks Self-Employed feels somewhat isolated from the broader QuickBooks ecosystem. If your needs grow, you are looking at a migration to QuickBooks Simple Start rather than a straightforward upgrade.

Where it excels: Good mobile app, reasonable price, mileage tracking, strong brand Where it could improve: Limited plan, upgrade path is disjointed, US-centric features

4. Coconut — Best for Simplicity

Price: Free–£12/month | MTD: Yes | Self Assessment filing: Yes (paid plans)

Coconut was built for UK sole traders and freelancers who find traditional accounting software intimidating. It connects to your bank, pulls in transactions, and lets you categorise them with simple swipes. The free plan covers basic bookkeeping, and paid plans add tax estimates and filing.

The simplicity is both its strength and its limitation. If you have straightforward finances — one income source, standard expenses — Coconut is excellent. If you have anything more complex, you will hit its limits quickly.

Where it excels: Simplicity, approachable design, good free plan Where it could improve: Manual categorisation only, limited for complex situations

See our Accounted vs Coconut comparison for more detail.

5. Xero — Best for Accountant Collaboration

Price: £15–£47/month | MTD: Yes | Self Assessment filing: Via accountant

Xero is the most widely used cloud accounting platform in the UK, and virtually every accountant knows how to use it. If you work with an accountant, Xero makes collaboration seamless. The app marketplace offers integrations for almost everything.

For self-employed users working alone, though, Xero can be overwhelming. The interface is built around double-entry bookkeeping, and the pricing is steep once you need bank reconciliation and expenses on the same plan. It is a powerful tool, but it is not designed for solo self-employed workers.

Where it excels: Accountant collaboration, massive app ecosystem, invoicing Where it could improve: Complex for sole traders, expensive, not self-employed-focused

6. Sage Accounting — Best for Established Businesses

Price: £12–£26/month | MTD: Yes | Self Assessment filing: Yes

Sage has been in the UK market for decades, and the cloud version is a solid, reliable platform. Bank feeds, invoicing, receipt capture, and MTD submissions all work well. The UK-based support team is a genuine advantage if you prefer phone support.

For self-employed users, Sage's main drawback is that it was not designed with you as the primary audience. The feature set skews towards small businesses with employees and stock. It works for self-employed users, but you are paying for functionality you will not use.

Where it excels: Established brand, UK support, reliable, good reporting Where it could improve: Not self-employed-focused, some legacy complexity

Features That Matter Most

Bank Feeds

All six apps offer Open Banking connections to major UK banks. In practice, reliability varies. Some apps lose connections more frequently than others, requiring you to re-authenticate. Accounted and Xero tend to have the most reliable connections in our testing.

Receipt Management

This is where differences become stark. Coconut, QuickBooks, and FreeAgent offer basic receipt capture — photograph the receipt in the app, and it attaches to a transaction. Xero's receipt capture extracts data using OCR and suggests matches.

Accounted's WhatsApp-based receipt capture is in a different category. You send a photo to Penny on WhatsApp (the app you already have), and the AI extracts the supplier, amount, date, VAT, and category, then matches it to the correct bank transaction. No separate app, no learning curve.

Tax Calculations

FreeAgent and Accounted have the strongest tax calculation engines for self-employed users. Both handle Income Tax, National Insurance, and payments on account. Accounted additionally supports 11 of 13 Self Assessment schedules, which matters if you have multiple income sources.

Coconut and QuickBooks provide basic tax estimates that are useful for budgeting but less comprehensive for complex situations.

MTD Compliance

With Making Tax Digital now live for higher earners, MTD compliance is non-negotiable. All six platforms are HMRC-recognised, but the experience of submitting quarterly updates varies. Accounted and FreeAgent make the process most seamless for self-employed users. Read our complete MTD guide for more on this.

Our Recommendation

If you are self-employed in the UK and want the least amount of bookkeeping work, Accounted is the best choice. Penny handles the categorisation, receipt matching, and tax calculations automatically, and the WhatsApp integration means you do not need to learn a new app. Check our pricing page to see what is included.

If budget is your top priority and you bank with NatWest, FreeAgent is hard to beat at £0. It requires more manual work, but it is comprehensive.

If you already work with an accountant, ask which platform they prefer. An accountant who is proficient in Xero will add more value through Xero than through a platform they are learning on the job.

Whatever you choose, the important thing is to choose something and use it consistently. Irregular bookkeeping creates more problems than the wrong software ever will. Our best bookkeeping software guide has additional detail if you want to dig deeper into the comparison.
