HMRC

Here's a practical breakdown of UK tax software, split by who typically uses it — since "tax software" means different things for individuals vs. small businesses vs. accountants.

For Individuals & Self-Assessment (Sole Traders, Landlords, Side Income)

1. HMRC's own online Self Assessment service – Free and mandatory as the filing endpoint (even paid software ultimately submits through HMRC's systems for most simple cases). Fine if your return is straightforward.

2. TaxCalc – Widely used by both individuals and accountants for Self Assessment, well regarded for handling more complex situations (multiple income sources, capital gains, etc.) at a reasonable one-off price.

3. GoSimpleTax – A popular, user-friendly option aimed specifically at freelancers, landlords and sole traders who want SA100 filing without needing an accountant.

These three dominate the personal tax-return space in the UK, especially now that HMRC has tightened requirements around digital record-keeping.

For Small Businesses & Sole Traders (Bookkeeping + Tax + MTD)

Sage – Sage is a cloud-based UK tax software platform that lets businesses and accountants manage tax submissions, accounting, payroll, and HMRC compliance all in one system, and is a strong fit for UK small to medium-sized businesses and accounting professionals needing integrated tax and accounting tools. Users rely on its Making Tax Digital for VAT functionality to stay compliant. It's a very well-known name in the UK, covering tax, accountants, HR and more.

QuickBooks – QuickBooks' accounting software is HMRC-recognized and offers a range of smart, simple solutions for managing cash flow, sending invoices, and sorting expenses, connecting to your bank for automated real-time feeds and cash flow insights. It's one of the most commonly recommended tools for VAT-registered businesses needing MTD compliance.

Xero – Very popular with UK small businesses and freelancers, especially those who also use an accountant, since most UK accountancy firms support Xero natively. Good for invoicing, bank feeds, and MTD VAT submissions.

FreeAgent – Particularly popular because it's given away free with certain NatWest, RBS, and Mettle business bank accounts. Strong for sole traders and small limited companies wanting an all-in-one invoicing/tax/bookkeeping tool.

Crunch / ANNA / Coconut – App-based, aimed at freelancers and contractors who want tax estimates, expense tracking, and Self Assessment prep bundled with (in Crunch's case) actual accountant support.

For Accountants & Larger Firms

IRIS, TaxDome, and VT Software show up frequently in professional comparisons for practice management and multi-client tax filing. Tax preparation software helps individuals, businesses, and tax professionals prepare, calculate, and file tax returns accurately and efficiently, automating workflows like income reporting, deduction calculations, and compliance checks.

Filing taxes in the UK can range from a straightforward task to a stressful, time-consuming chore—especially with the introduction of Making Tax Digital (MTD) for Income Tax Self Assessment (ITSA).

Since April 2026, sole traders and landlords with a qualifying income over £50,000 have been legally required to use HMRC-compatible software for quarterly digital updates (with the threshold dropping to £30,000 in April 2027). Because of this, simply using HMRC's free manual portal is no longer an option for many.

The best UK tax software options depend on whether you want a simple "fill-it-and-file-it" tool, a full bookkeeping suite, or an expert to handle it for you.

Category 1: Best "Done-With-You" Software (With Accountant Review)

If you want the convenience of an app but still want the peace of mind that a real human expert has checked your work before it goes to HMRC, these are the standout options.

1. Taxfix (formerly TaxScouts)

• Best for: Stress-free, expert-managed filing.
• How it works: TaxScouts recently rebranded as Taxfix. You log into their platform, answer a few basic questions, and upload your documents (invoices, P60, expenses). Taxfix then pairs you with a certified, UK-based accountant who prepares, optimises, and submits your Self Assessment return on your behalf.
• Cost: Packages typically range from £99 to £349 per return depending on the level of complexity and year-round support.
• Pros: Complete peace of mind; you don't actually have to fill in the scary HMRC boxes yourself.

2. QTax

• Best for: Budget-conscious sole traders wanting an accountant's stamp of approval.
• How it works: Purpose-built for UK freelancers and sole traders, QTax is a smart, AI-driven platform. It has clever features like receipt scanning and auto-categorisation, but its killer feature is that its annual fee includes a formal review by an ACCA-regulated accountant before your submission goes to HMRC.
• Cost: Highly competitive at around £49.99/year.
• Pros: Incredible value for a guided, AI-assisted return backed by professional oversight.

Category 2: Best Dedicated Self Assessment Software (No Bookkeeping Needed)

If you already track your numbers on a spreadsheet and just want a simple, direct interface to calculate your tax bill and submit it straight to HMRC, these tools are ideal.

3. GoSimpleTax

• Best for: Straightforward, manual Self Assessment filing.
• How it works: GoSimpleTax doesn’t try to be a full-blown bookkeeping software like Xero. Instead, it focuses purely on making the tax return process painless. It guides you through the traditional tax return forms (SA100, SA103, etc.), alerts you to potential errors, and suggests tax-saving deductions you might have missed.
• Cost: Around £58 to £60 per year.
• Pros: Extremely user-friendly, MTD-ready, and directly submits to HMRC with a live tax-liability calculator so you aren't surprised by your bill.

4. TaxCalc

• Best for: Complex tax situations (trusts, partnerships, residency issues).
• How it works: TaxCalc is a legendary brand in UK tax. Trusted by thousands of professional accounting firms, they also sell a highly popular consumer version (TaxCalc Individual). It uses a "wizard" interface called SimpleStep to take you through your returns and Validation checks to flag up any discrepancies.
• Cost: Around £34+ depending on the complexity of the return.
• Pros: Robust, highly accurate, and handles virtually every niche tax scenario that simpler online apps might struggle with.

Category 3: Best Full Bookkeeping & Invoicing Software (With Built-In Tax Filing)

If you are running a business or freelancing full-time, you probably want to manage your day-to-day invoices, track bank feeds, and calculate tax all in one platform.

5. FreeAgent

• Best for: Freelancers and contractors (especially those banking with NatWest/Mettle).
• How it works: FreeAgent is a fully-featured accounting platform designed specifically for the self-employed. It automatically pulls in transactions from your bank, helps you send invoices, tracks expenses, and uses this live data to populate your Self Assessment form automatically throughout the year.
• Cost: Normally around £19–£33/month, but 100% free if you have a business bank account with NatWest, Royal Bank of Scotland, Ulster Bank, or Mettle.
• Pros: Clean, non-jargon interface. Free accounting for millions of UK business owners.

6. Xero & QuickBooks

• Best for: Growing small businesses with complex needs (and those working with an accountant).
• How it works: These are the two biggest heavyweights in global cloud accounting. Both integrate seamlessly with HMRC for Making Tax Digital (VAT and Income Tax) and connect to almost every major UK bank. They are ideal if you plan to hire employees, manage inventory, or have an accountant who logs in to do your books.
• Cost: Ranges from £10 to £40+ per month depending on features and promotional offers.
• Pros: Unmatched integrations and features. Practically every accountant in the UK knows how to use Xero.

7. Sage

• Best for: Trustworthy, established compliance with a free entry point.
• How it works: Sage is a massive name in UK business finance. In response to HMRC's strict MTD ITSA rules, Sage introduced a free MTD software version for sole traders. This makes it a great entry point to ensure you are meeting quarterly digital record-keeping requirements without immediate monthly software fees.
• Pros: Highly reliable, decades of HMRC compliance experience, and excellent customer support.

Which one should you choose?

• If you want it totally off your plate: Go with Taxfix. You pay a bit more, but a qualified human accountant does the hard work for you.
• If you want cheap, guided filing with an accountant safety net: QTax is the best value in this space.
• If you bank with NatWest, RBS, or Mettle: It is a no-brainer to use FreeAgent since it is entirely free and handles your bookkeeping and tax in one place.
• If you just want to do your own Self Assessment without changing your spreadsheets: GoSimpleTax is incredibly easy and avoids the confusing layout of the standard HMRC portal.

For UK residents handling Self Assessment (SA) tax returns, VAT, or Making Tax Digital (MTD) compliance, popular and widely used tax/accounting software options include GoSimpleTax, FreeAgent, Xero, QuickBooks, Sage, and TaxCalc.

These stand out in recent reviews and comparisons for individuals, sole traders, freelancers, landlords, and small businesses. HMRC does not endorse specific products but maintains lists of recognised/approved commercial software for direct filing of SA returns, VAT, and MTD submissions—always verify compatibility on GOV.UK.

Choices depend on your situation (e.g., simple SA vs. full bookkeeping + invoicing + quarterly MTD updates). Prices are approximate and can vary with promotions, plans, or add-ons—check current details directly. Many offer trials.

Top Recommendations for Individuals/Sole Traders (Self Assessment Focus)

• GoSimpleTax: One of the most frequently recommended for straightforward or guided SA filing. It offers an intuitive, form-based or step-by-step interface with tax estimates, optimisation tips, and support for various schedules (including property/CGT). Affordable (often ~£50–£70 per tax year) and HMRC-recognised for individuals/agents. Good for those wanting to file themselves without full accounting software.
• FreeAgent: Excellent for freelancers, contractors, and sole traders needing bookkeeping alongside SA filing. Features bank feeds, invoicing, expense tracking, and direct HMRC submission (SA and MTD-ready). Often praised for its clean UK-focused UX. Pricing starts around £19/month (or free/long-term free with qualifying NatWest, RBS, Ulster Bank, or Mettle accounts). Strong MTD support.
• TaxScouts/Taxfix or similar done-for-you services: Ideal if you prefer a service where an accountant handles everything (from ~£119–£169+ per year). Less “software” and more hybrid support.
• HMRC’s free online Self Assessment service: Best for very simple returns (e.g., employment income, basic interest/dividends). No-frills but sufficient for many; not MTD-ready for quarterly updates where required.

Popular Full Accounting Software (Often Used for Tax + More)

These handle SA filing (directly or via integrations), VAT returns, invoicing, and MTD compliance, making them common choices for growing sole traders or small businesses:

• Xero: Highly regarded all-rounder with strong bank reconciliation, reporting, app ecosystem, and MTD/VAT/SA support. Popular across business sizes; pricing from ~£16/month (discounts often available).
• QuickBooks (Intuit): User-friendly for sole traders/self-employed, with solid bookkeeping, mobile features, VAT handling, and SA options. Starts around £15–£16/month.
• Sage (including Sage Accounting/Sole Trader): Strong UK compliance focus, MTD-ready options (including free tiers for very basic use), invoicing, and payroll ties. Widely used; competitive pricing with promotions.

For Accountants or More Complex Needs

TaxCalc is frequently cited as one of the most widely used professional platforms (alongside IRIS and BTC Software) for SA, corporation tax, and compliance work. It supports multiple returns and is popular among practices.

Quick Tips for Choosing and Using

• Simple needs — Start with HMRC free or GoSimpleTax.
• Bookkeeping + tax — FreeAgent, Xero, QuickBooks, or Sage.
• MTD compliance (now relevant for many sole traders/landlords above thresholds) — Ensure the software is HMRC-recognised for digital records and quarterly updates.
• Check Trustpilot/reviews for real-user feedback on support and ease of use; many integrate with banks or accountants.
• Prices often include filing; watch for extras like phone support or advanced features.
• Always confirm the latest HMRC recognition list, as it updates.

If your situation involves specific elements (e.g., property income, limited company, high volume, or VAT schemes), provide more details for tailored suggestions. Consider consulting an accountant for complex affairs.
