Self-Employed Accounting Software UK: Full Guide

Choosing accounting software when you are self-employed in the UK should be straightforward. You earn money, you spend money, you need to tell HMRC about both. But the number of options, the jargon, and the conflicting advice online make it surprisingly difficult to pick the right tool.

This guide cuts through the noise. We explain what self-employed people actually need from their software, compare the main options honestly (including our own), and help you make a decision based on your specific situation rather than generic marketing claims.

Why Self-Employed People Need Specific Software

If you are self-employed — a sole trader, freelancer, or contractor filing Self Assessment — your needs are different from a limited company director. You do not need payroll. You probably do not need multi-currency support. You are unlikely to need a purchase order system.

What you do need is:

MTD Compliance

Making Tax Digital for Income Tax is now live for self-employed people earning over £50,000, with the £30,000 threshold starting in April 2027. This means quarterly updates to HMRC summarising your income and expenses. Your software must be HMRC-recognised and capable of submitting these digitally.

If you earn under the threshold, MTD does not apply yet — but it will eventually. Choosing MTD-compatible software now avoids a disruptive switch later.

Tax Calculations

Your software should calculate your Income Tax liability, Class 2 and Class 4 National Insurance, and payments on account throughout the year. Without this, you are guessing what you owe until filing time — and that guess is often wrong.

Expense Categorisation

HMRC requires your expenses in specific categories for Self Assessment. Office costs, travel, professional fees, and advertising are all separate categories. Your software should either categorise automatically or make manual categorisation simple.

Self Assessment Filing

Filing your SA100 directly from your software saves you from re-entering all your figures on the HMRC website. It also reduces the risk of transcription errors.

Receipt Storage

HMRC requires you to keep records for at least five years. Digital receipt storage linked to transactions is the simplest way to comply.

Bank Feeds

Automatic transaction imports from your bank save hours of manual data entry and ensure your records are complete.

The Complete Comparison

We have grouped the main options by approach: AI-automated, traditional cloud, free, and service-based.

AI-Automated: Accounted

Price: From £12/month | Approach: AI does the bookkeeping for you

Accounted was built specifically for self-employed UK workers. Penny, the AI bookkeeper, connects to your bank, imports transactions daily, and categorises them automatically using a three-tier reasoning system. High-confidence categorisations happen without your input. Lower-confidence ones get flagged for a quick review.

Receipt management works through WhatsApp — send a photo to Penny and the AI extracts the details, categorises the expense, and matches it to your bank transaction. No separate app needed.

Tax estimates update in real time. Self Assessment filing and MTD quarterly submissions are built in. Accounted supports 11 of 13 SA schedules.

Best for: Self-employed people who want minimal involvement in bookkeeping. If you would rather focus on your work than your accounts, Accounted is designed for you.

Honest limitations: No invoicing yet, UK only, newer to market.

Traditional Cloud: Xero

Price: £15–£47/month | Approach: Professional accounting platform you manage yourself

Xero is the market leader in the UK. It offers comprehensive accounting features — invoicing, bank reconciliation, reporting, and an enormous ecosystem of integrations. Virtually every accountant in the UK knows Xero.

For self-employed users, Xero's challenge is complexity. The interface is built around double-entry bookkeeping concepts, and the pricing structure pushes most users to the £33/month plan for full functionality. You need to learn how to use it, or work with an accountant who manages it for you.

Best for: Self-employed people who work with an accountant, or those who need extensive integrations.

Honest limitations: Complex for sole traders, expensive, not designed for self-employed users specifically.

Traditional Cloud: QuickBooks

Price: £12–£32/month | Approach: Established platform with a self-employed-specific plan

QuickBooks Self-Employed is a separate product aimed at freelancers and sole traders. It handles income and expense tracking, mileage logging, and basic tax estimates at a reasonable price point.

The main strength is the mobile app, which is polished and practical for on-the-go expense entry. The limitation is that the Self-Employed plan is quite separate from the main QuickBooks ecosystem — upgrading means migrating, not simply unlocking features.

Best for: Self-employed people who want a recognisable brand with a decent mobile app.

Honest limitations: Limited Self-Employed plan, upgrade path is awkward, US-centric.

Traditional Cloud: Sage

Price: £12–£26/month | Approach: Established UK platform with strong support

Sage has been in the UK accounting market for decades. The cloud version handles bank feeds, invoicing, receipt capture, and MTD compliance reliably. UK-based phone support is a genuine advantage.

For self-employed users, Sage is more software than most need. The feature set is geared towards small businesses with employees and stock, and you pay for functionality you will not use.

Best for: Self-employed people who prefer established brands with phone support.

Honest limitations: Not self-employed-focused, some interface complexity.

Free: FreeAgent (via NatWest)

Price: £14.50/month (free with NatWest/RBS) | Approach: Full-featured platform subsidised by your bank

FreeAgent's free access through NatWest, RBS, and Ulster Bank business accounts is the best free accounting offer in the UK. You get the full product — bank feeds, invoicing, expense tracking, Self Assessment filing, and MTD compliance — without paying a penny.

The tax timeline is excellent, giving you a visual overview of what you owe and when. The interface is cleaner than Xero's, though less modern than the newest platforms.

Best for: Self-employed people who bank with NatWest or RBS.

Honest limitations: Manual categorisation, interface feels dated, limited automation.

Free: Coconut

Price: Free–£12/month | Approach: Simplified bookkeeping for sole traders

Coconut strips away complexity and focuses on the basics — bank transactions, simple categorisation, and tax estimates. The free plan covers basic bookkeeping, and paid plans add filing and more features.

Best for: Self-employed people who want the simplest possible experience and have straightforward finances.

Honest limitations: Manual categorisation, limited features, basic reporting.

See our Accounted vs Coconut comparison.

Service-Based: Crunch

Price: From £79.50/month | Approach: Software plus dedicated accountant

Crunch bundles software with a human accountant who manages your finances. You get professional oversight, tax advice, and HMRC communication handled for you.

Best for: Self-employed people with complex finances or who want zero involvement.

Honest limitations: Expensive, dependency on accountant availability, less control.

Service-Based: TaxScouts

Price: From £169/year | Approach: Annual filing by an accredited accountant

TaxScouts pairs you with an accountant who files your Self Assessment. It is a once-a-year service, not ongoing software.

Best for: Self-employed people who want professional filing without a monthly commitment.

Honest limitations: Annual only, no year-round bookkeeping, no MTD support.

How to Decide

By Budget

| Budget | Recommended | |--------|-------------| | £0/month | FreeAgent (NatWest) or Coconut free plan | | Under £15/month | Accounted (£12/month) | | £15–£50/month | Xero, QuickBooks, or Sage | | £80+/month | Crunch managed service |

By Priority

| Priority | Recommended | |----------|-------------| | Minimum effort | Accounted — Penny automates the bookkeeping | | Best free option | FreeAgent via NatWest | | Accountant collaboration | Xero — universal accountant support | | Human oversight | Crunch — dedicated accountant | | Invoicing | Xero or QuickBooks — strongest invoicing | | Pure simplicity | Coconut — stripped back to basics |

By Situation

Just starting out — Start with Coconut free or FreeAgent (NatWest). Get familiar with what bookkeeping involves before committing to a paid platform.

Earning over £50,000 — MTD is mandatory. Choose Accounted, Xero, or FreeAgent for reliable quarterly submissions.

Earning £30,000–£50,000 — MTD starts April 2027. Get set up on compatible software now rather than rushing later.

Multiple income sources — Choose Accounted (11 SA schedules) or pair another platform with GoSimpleTax for filing.

Working with an accountant — Ask which platform they prefer. Most will say Xero.

Want to understand finances — Any platform where you do the categorisation (Xero, Quickfile, Pandle) teaches you about your business finances through hands-on use.

The MTD Factor

Making Tax Digital changes the equation for many self-employed people. If you earn above the threshold, you cannot get away with a spreadsheet and annual filing any more. You need software that maintains digital records and submits quarterly updates.

The platforms best positioned for MTD are those where quarterly submissions are a natural by-product of keeping your books up to date — Accounted and FreeAgent excel here. Platforms where you need to manually ensure everything is categorised before each deadline — Quickfile, Pandle — create more work.

Our complete Making Tax Digital guide covers everything you need to know about compliance, deadlines, and penalties.

Our Recommendation

For most self-employed people in the UK, Accounted offers the best balance of automation, tax management, and value. Penny handles the bookkeeping that other platforms expect you to do yourself, and the tax calculations, MTD submissions, and Self Assessment filing are all integrated.

At £12/month, it costs less than a mediocre lunch. The time it saves you — and the errors it prevents — make it the most practical investment a self-employed person can make in their business admin.
