What AI said about tax software in the United Kingdom in August 2026

Best UK tax software people actually use — shortlist

For most people in the United Kingdom, I’d narrow it down like this:

As of 2026, a key UK-specific point is Making Tax Digital for Income Tax: from 6 April 2026, some sole traders and landlords must use compatible software to keep digital records, send quarterly updates and submit the tax return; HMRC also says all software in its MTD finder has been through HMRC’s recognition process, but HMRC does not recommend one product over another. (gov.uk)

My top recommendations

1. FreeAgent — best all-rounder for UK freelancers and small sole traders

Pick this if: you’re self-employed, a contractor, freelancer, consultant, or run a small service business.

FreeAgent is very popular in the UK because it’s built around UK tax workflows: invoices, expenses, bank feeds, VAT, Self Assessment-style tax estimates and small-business accounting. It is also listed by HMRC for Self Assessment submissions, supporting common individual return schedules such as SA100, employment, self-employment and property pages. (gov.uk)

Why people use it:

• Easy for non-accountants.
• Strong for freelancers and contractors.
• Often free or discounted via UK banking relationships, especially NatWest/RBS/Mettle-style bundles.
• Good if you want bookkeeping and tax in one place.

Watch out: not as flexible as Xero for more complex businesses or larger finance teams.

---

2. Xero — best mainstream small-business accounting platform

Pick this if: you run a growing business, want accountant support, or expect to scale beyond basic Self Assessment.

Xero is one of the big UK cloud accounting names and is commonly recommended by accountants. A 2026 comparison of the leading Making Tax Digital Income Tax apps identifies Xero, QuickBooks, Sage and FreeAgent as the four major platforms most likely to gain the greatest market share for sole-trader MTD, citing their large user bases, accountant support and UK tax-rule integrations. (financialaccountant.co.uk)

Why people use it:

• Very strong accountant/bookkeeper ecosystem.
• Good bank feeds, invoicing, VAT, reporting and integrations.
• Better than many rivals for businesses that may grow.

Watch out: Xero’s full tax workflow often makes most sense if your accountant is involved. HMRC’s Self Assessment supplier list shows Xero Tax as available for agents, not individuals, on that list. (gov.uk)

---

3. QuickBooks Online / QuickBooks Sole Trader — best for simple small-business bookkeeping

Pick this if: you want a mainstream, easy-to-use accounting app with strong bank feeds and mobile workflows.

QuickBooks is one of the main UK small-business accounting platforms, and it is one of the “big four” products compared for MTD Income Tax alongside Xero, Sage and FreeAgent. The Institute of Financial Accountants notes that QuickBooks replaced its UK Self-Employed product with QuickBooks Sole Trader on the main QuickBooks platform. (financialaccountant.co.uk)

Why people use it:

• Familiar brand.
• Good mobile app and bank-feed automation.
• Often competitively priced for sole traders.
• Good for invoices, expenses and basic bookkeeping.

Watch out: for full Self Assessment filing, check exactly which QuickBooks product/plan supports your situation before committing.

---

4. Sage Accounting / Sage Personal Tax / Sage Taxation — best established UK business option

Pick this if: you want a long-established UK accounting brand, payroll integration, or your accountant already uses Sage.

Sage remains one of the best-known UK accounting software brands. HMRC’s Self Assessment software list includes Sage Personal Tax for agents and individuals, and Sage Taxation for agents, with broad SA100 schedule support. (gov.uk)

Why people use it:

• Long UK track record.
• Strong accounting/payroll reputation.
• Familiar to many accountants and older businesses.
• Suitable for businesses that want a more traditional accounting feel.

Watch out: some users find Sage less slick than newer cloud-first tools like Xero or FreeAgent.

---

5. TaxCalc — best dedicated UK tax-return software

Pick this if: you specifically want to file tax returns rather than run day-to-day bookkeeping.

TaxCalc is one of the strongest UK tax-only products. HMRC lists TaxCalc for individuals and agents, with all individual, partnership and trust schedules supported on the Self Assessment commercial software list. (gov.uk) TechRadar also describes TaxCalc as HMRC-recognised and suitable for individuals, limited companies and accountancy firms, with a step-by-step tax-return process. (techradar.com)

Why people use it:

• Strong for Self Assessment, partnerships, trusts and company tax workflows.
• Popular with accountants and confident self-filers.
• Good if you already keep records elsewhere and just need filing software.

Watch out: it’s more “tax filing” than modern all-in-one bookkeeping.

---

6. GoSimpleTax — best simple Self Assessment app

Pick this if: you’re an individual, landlord or sole trader who wants a guided Self Assessment return.

GoSimpleTax is listed by HMRC for Self Assessment, covering a wide range of individual return schedules including employment, self-employment, property, foreign income and capital gains pages. (gov.uk) TechRadar describes it as a tax-focused product rather than a full accounting system, with receipt scanning, mobile apps and a guided filing process. (techradar.com)

Why people use it:

• Easier than using HMRC’s forms directly.
• Good for landlords and individuals with extra income.
• Lower commitment than a full accounting suite.

Watch out: it is not a full bookkeeping/accounting platform like Xero, FreeAgent, QuickBooks or Sage.

---

7. IRIS Elements / IRIS Personal Tax — best for accountancy practices

Pick this if: you’re an accountant, tax adviser or have more complex tax affairs handled through a practice.

IRIS is a long-established UK practice software provider. HMRC lists IRIS Elements Tax, IRIS Personal Tax, IRIS Business Tax and IRIS Trust Tax for different Self Assessment use cases, mainly aimed at agents/practices, with broad schedule support. (gov.uk)

Why people use it:

• Widely used in professional accountancy practices.
• Strong for multi-client tax work.
• Better suited to agents than ordinary taxpayers.

Watch out: probably overkill if you’re just filing your own straightforward Self Assessment.

---

Also worth knowing

• BTCSoftware by Bright — respected in accountancy practices; HMRC lists BTC SA Solution for agents with all individual, partnership and trust schedules supported. (gov.uk)
• Absolute Tax / Absolute Accounting Software — practical for accountants and users who want lower-cost tax/bridging-style tools; HMRC lists Absolute Integrated and Absolute Topup for Self Assessment use. (gov.uk)
• Zoho Books — increasingly relevant for small businesses; HMRC lists Zoho Books for individual Self Assessment, but with narrower schedule support than TaxCalc or GoSimpleTax. (gov.uk)
• Crunch — good if you want software plus human accountants, especially for freelancers and small limited companies; TechRadar highlights it as a software-plus-adviser option. (techradar.com)

Quick buying advice

If you’re in the UK and want the safest mainstream choice:

1. Freelancer / contractor / sole trader: start with FreeAgent or QuickBooks Sole Trader.
2. Growing small business: use Xero if your accountant supports it; otherwise compare QuickBooks and Sage.
3. Simple Self Assessment only: use GoSimpleTax or TaxCalc.
4. Limited company self-filing: look at TaxCalc or FreeAgent; many Xero/QuickBooks users still rely on an accountant or add-on for company tax.
5. Accountancy practice: shortlist TaxCalc, IRIS, Sage Taxation, BTCSoftware by Bright and Xero Tax.

My default recommendation for most UK individuals would be FreeAgent if you also need bookkeeping, or GoSimpleTax/TaxCalc if you only need to file a Self Assessment return. For businesses with an accountant, I’d usually choose Xero or QuickBooks, depending on what your accountant prefers.

Here's a rundown of the UK tax software people actually rely on, split into personal (Self Assessment) and business/accounting categories, since most people search for one or the other.

For Self Assessment (individuals, sole traders, landlords)

HMRC's own free online portal is worth mentioning first: HMRC's free online portal handles the vast majority of self-assessment returns perfectly well. However, third-party software earns its cost by catching errors before submission, providing a clearer interface, handling complex income types more easily, and — from April 2026 — enabling MTD ITSA quarterly submissions.

The most commonly used paid alternatives are:

• GoSimpleTax
• TaxCalc
• Taxfiler
• Untied

These are the names that regularly come up in UK comparisons for handling Self Assessment, especially for people with side income, rental property, or self-employment.

For businesses and contractors (accounting + tax combined)

Sage is one of the biggest and most trusted names in the UK market. 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. It's particularly known for VAT: many users manage VAT submissions and integrate payroll with HMRC through it, relying on its MTD for VAT functionality to stay compliant. TechRadar echoes this, noting Sage Business Cloud Accounting is just one part of a broader ecosystem from Sage that covers tax, accountants, HR and more, and it's a very well-known name in the UK, up to speed with HMRC's Making Tax Digital campaign, offering something for businesses of all sizes — though it might not be the cheapest, you get the backing of a trusty brand.

QuickBooks is the other heavyweight, especially popular with freelancers and small businesses: 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, providing cash flow insights, and including pre-set reports.

Xero also comes up frequently as one of the top-ranked options for UK tax filing, alongside more accountant-focused tools like VT Software and IRIS Exchequer.

For accountancy firms managing multiple clients

If you're an accountant or bookkeeper (rather than an individual filer), TaxDome is increasingly popular for practice management combined with filing: TaxDome is the single source of truth for tax, bookkeeping, and accounting firms, built so the move feels manageable from week one, with the client app rated 4.9/5 across 35,000+ reviews.

Quick recommendation by situation

One important context point for 2026: with Making Tax Digital for Income Tax (MTD ITSA) rolling

In the UK, the "best" tax software depends entirely on your specific situation. Whether you are a sole trader looking to log expenses throughout the year, a landlord with rental income, an employee with a side hustle, or simply someone who wants the peace of mind that a professional is double-checking your Self Assessment, there is a tailored tool for you.

With HMRC's Making Tax Digital (MTD) rules phasing in, choosing a platform that plays nicely with digital record-keeping is more important than ever.

These are the top tax software brands and products that people in the UK actually use, categorised by how they fit different needs.

1. Best for "Hands-Off" Assisted Filing: Taxfix (formerly TaxScouts)

If you dread the thought of completing your tax return yourself but don't want to pay £300+ for a high-street accountant, Taxfix is the perfect middle ground.

• How it works: You log onto their website or app, answer a few simple questions about your income, and upload your documents (like P60s, expense receipts, or invoices). Taxfix then pairs you with a vetted, UK-based professional accountant who prepares your Self Assessment, finds allowable expenses, and files it directly to HMRC on your behalf.
• The Rebrand: If you used TaxScouts in the past, they were acquired by European giant Taxfix and fully rebranded to Taxfix. The service remains the same accountant-led, stress-free model.
• Cost: Around £169 per return (flat fee).
• Best for: High earners, landlords, expats, and freelancers who want the peace of mind of an accountant checking their work, without the massive bill.

---

2. Best for DIY Self Assessment: GoSimpleTax

For those who want to file their own return but find the official HMRC portal frustrating and confusing, GoSimpleTax is the most popular alternative.

• How it works: It is an HMRC-approved, cloud-based platform that guides you step-by-step through your Self Assessment. As you input your numbers, it calculates your tax bill in real-time and alerts you if you've missed potential tax-saving expenses. When you're done, you can submit directly to HMRC with one click.
• Key feature: It offers error-checking algorithms that flag inconsistencies, drastically reducing the chances of a stressful HMRC inquiry.
• Cost: Plans start at £69.99 per year. Top tip: If you are a member of the consumer group Which?, you can often get a massive discount, dropping the price to £34.99.
• Best for: Sole traders, freelancers, and landlords who want a straightforward, low-cost way to do their own taxes.

---

3. Best All-in-One for Sole Traders (Free if you bank with NatWest/RBS/Mettle): FreeAgent

If you work for yourself, bookkeeping and tax filing are two sides of the same coin. FreeAgent is highly regarded because it bridges that gap perfectly.

• How it works: It is a comprehensive cloud accounting software that handles invoicing, daily expense tracking, and connects directly to your business bank feed. Because it tracks your income and expenses in real-time, it constantly populates your Self Assessment forms in the background. At the end of the tax year, you simply review the pre-filled forms and submit them straight to HMRC from the app.
• The Killer Feature: FreeAgent is completely free for as long as you have an active business bank account with NatWest, Royal Bank of Scotland, Ulster Bank, or a Mettle account. If you qualify, this is an absolute no-brainer.
• Best for: Active freelancers, contractors, and sole traders who want continuous, year-round bookkeeping paired with easy tax filing.

---

4. Best for Complex Tax Situations: TaxCalc (Individual)

TaxCalc is a legendary brand in the UK tax world. While heavily used by professional firms, they sell an "Individual" version that is exceptionally robust.

• How it works: TaxCalc uses a wizard called SimpleStep. Instead of looking like scary tax forms, it asks you straightforward questions and takes you through the return section by section.
• Key feature: It is brilliant at handling very niche or complex tax scenarios, such as multiple income streams, foreign dividends, complex capital gains tax (CGT), and trust returns.
• Cost: Around £34 to £40 depending on the exact package.
• Best for: Tech-savvy DIYers with complex financial situations who want a highly logical, professional-grade wizard to guide them.

---

5. Best Modern Bookkeeping Alternatives: Cuppa or ANNA Money

If you prefer managing your life entirely via smartphone, a new wave of modern apps has emerged.

• Cuppa: A sleek, highly affordable app (£4.50/month) that focuses on continuous, day-to-day expense tracking, mileage logging, and live tax estimates. It is designed purely for sole traders who want to stay organized without paying for complex corporate bookkeeping features they will never use.
• ANNA Money: Primarily a business current account, but it features a very powerful, built-in "Terrier" tax tool that automatically categorises your expenses and helps calculate and submit your Self Assessment directly to HMRC.

---

6. The "Big Three" Small Business Options: Xero, QuickBooks, & Sage

If you run a registered Limited Company, are VAT-registered, or employ staff, you should look at the heavyweight small-business accounting platforms.

• Xero / QuickBooks / Sage: These are full-scale accounting platforms. They allow you to run payroll, manage VAT, track invoices, and comply fully with Making Tax Digital.
• Filing Taxes: While these platforms can handle VAT and basic sole trader tax submissions, they are typically designed for you to keep your records neat so that your local chartered accountant can log in, pull the data, and file your Corporation Tax or Self Assessment on your behalf.

Summary: Which should you choose?

• If you want a qualified accountant to do the work online for a fixed price, go with Taxfix.
• If you want a quick, cheap, but error-proof DIY filing tool, go with GoSimpleTax.
• If you want full bookkeeping software for free via your bank, go with FreeAgent.
• If you have a complex return (e.g., residency issues, foreign assets, trusts), go with TaxCalc.

If you want tax software people actually use in the UK, the strongest mainstream options are QuickBooks, Xero, TaxCalc, GoSimpleTax, and FreeAgent; for accountants and practices, IRIS, TaxCalc, and Xero Tax are especially common choices. The best option depends on whether you are filing Self Assessment, running MTD VAT, or need a full accounting platform with tax built in.

• QuickBooks UK — best for small businesses and sole traders who want accounting plus tax in one place; it is positioned as HMRC-compliant tax return software in the UK.
• Xero — one of the most widely used UK accounting platforms, and its tax tools are often recommended for businesses already using Xero for bookkeeping.
• TaxCalc — a strong choice for UK accountants and serious self-employed users; it is built specifically for UK tax and practice workflows.
• GoSimpleTax — a simple, self-assessment-focused option for individual tax returns and landlords who want something lighter-weight.
• FreeAgent — popular with freelancers and small businesses, especially where invoicing, expenses, and tax estimates need to work together.
• IRIS OpenTax / IRIS tax tools — more practice-oriented software used by accountants and firms that need controlled workflows and audit trails.
• HMRC-recognised MTD software from the GOV.UK list — if your priority is Making Tax Digital, the government’s software finder is the safest way to confirm compatibility.

A practical shortlist by use case:

If you want the most broadly recommended names in the UK market, I’d start with Xero, QuickBooks, TaxCalc, FreeAgent, and GoSimpleTax. If you tell me whether you’re self-employed, a landlord, a limited company, or an accountant, I can narrow this to the best 3 for your situation.

If you’re in the UK and need to sort out your tax return, the “best” software really depends on whether you’re a self-employed individual, a freelancer, or a small business owner. Here are the top, widely-used options that people actually rely on in the UK:

1. HMRC’s Own Free Service

For straightforward personal tax returns (mostly employment income, some savings interest, or a small amount of self-employment), HMRC’s online Self Assessment is free and does the job. It’s not fancy, but it’s reliable and handles the basics. Use this if your tax affairs are simple and you don’t want to pay a penny.

2. GoSimpleTax

Very popular for individuals and freelancers who want a simple, low-cost way to file. It’s HMRC-recognised, works like a spreadsheet, lets you log income/expenses on the go, and auto-calculates your tax and NICs. Often recommended on money-saving forums because it’s much cheaper than an accountant.

3. TaxScouts

A hybrid: you get online software + a real accountant. You fill in your income/expenses, upload documents, and a certified accountant checks everything and files it for you. Great if you’re self-employed but don’t want to learn the tech yourself. Flat fee per return, and they’ll chase HMRC on your behalf if needed.

4. FreeAgent

If you’re a freelancer or small business owner with a business bank account, this is a favourite. It does accounting, invoicing, expenses, and automatically prepares your Self Assessment tax return (including sole trader, partnership, and limited company). It’s often included free with certain business bank accounts (e.g., NatWest, Mettle), which is a big bonus.

5. QuickBooks

One of the biggest names in accounting software. Its Self Assessment module is solid, and it handles bookkeeping, VAT, payroll, and year-end taxes. If you run a small business and also need proper accounting, this is a good all-rounder.

6. Xero

Another market leader for small businesses and accountants. Xero doesn’t file the tax return automatically (you might need to use its accounting data to fill out extra forms), but it integrates with tax tools and is incredibly popular. Often used by bookkeepers and accountants, so if you use one, they’ll likely use Xero or QuickBooks.

7. TaxCalc

More aimed at professional accountants and tax advisers, but if you have a complex tax case (property, capital gains, foreign income), TaxCalc is very powerful and HMRC-recognised. It’s not the easiest for a casual filer, but it’s the go-to for experts.

8. Crunch

An online accountant that provides software + a real accountant for freelancers and small companies. Crunch handles your books, payroll, and Self Assessment automatically, and you get a named accountant for questions. Usually mentioned as a great value option for contractors.

9. Sage

Sage is classic UK accounting software, especially popular with small businesses and UK-based accountants. It handles full accounting, VAT, payroll, and year-end. You can use it to prepare your tax return (or hand the data to your accountant). It’s not the cheapest, but it’s well-established and reliable.

---

A few honest notes:

• If you’re on PAYE (employed) and have no other income, you don’t need any software – HMRC automatically deducts your tax.
• For simple situations, don’t overspend. HMRC’s own tool or GoSimpleTax (around £25–£30) is plenty.
• For freelancers with a decent income, FreeAgent or Crunch are great value because they bundle accounting and tax filing together.
• Always check the deadline (usually 31 January for online filing) and use HMRC’s official list of “recognised software” if you want to be extra safe.

Bottom line: Most people in the UK either use HMRC directly, GoSimpleTax (for a cheap DIY return), or FreeAgent/Crunch (if they’re self-employed and want it handled properly).

The best tax software in the UK focuses mainly on Self Assessment (SA100 and supplementary pages) for individuals, sole traders, freelancers, landlords, and partnerships, plus tools for VAT (Making Tax Digital/MTD), Corporation Tax (CT600), and full accounting. HMRC provides a free online Self Assessment service suitable for simpler returns, but many people use commercial HMRC-recognised software for better guidance, error-checking, calculations, integrations, record-keeping, and direct submission.

Popular choices that people actually use (based on reviews, Trustpilot feedback, freelancers/sole trader communities, and specialist round-ups) fall into DIY filing tools, full accounting platforms with tax features, and hybrid accountant-assisted services. Preferences depend on complexity (e.g., employment only vs self-employment + property + capital gains), whether you need year-round bookkeeping, MTD readiness (increasingly important for Income Tax Self Assessment), budget, and ease of use. Always verify current HMRC recognition and features on the official GOV.UK commercial software suppliers list.

Top DIY Self Assessment Filing Software

These guide you through forms, calculate tax, and submit directly to HMRC. Ideal if you keep basic records yourself.

• GoSimpleTax: One of the most frequently recommended and widely used options for everyday taxpayers, freelancers, landlords, and those with multiple income sources. It offers a clear guided interface, real-time calculations, tax-saving tips, support for many supplementary pages, integrations (e.g., with FreeAgent, Xero), and UK-based support (extended in peak periods like January). Highly awarded with strong user feedback for ease of use. Pricing is typically around £65–£106+ per tax year (cheaper with subscription; higher for one-off or partnerships/residency options; previous years available). Over 100,000+ returns filed historically.

• TaxCalc: Long-established, reliable, and popular for individuals wanting solid guidance plus more advanced needs (and heavily used by accountants/practices). Desktop or guided tools with wizards, automated checks, support for prior years, and add-ons. Competitive pricing often starting around £38+ for a basic individual return (add-ons extra). Good for those who prefer installable software or more control. HMRC-recognised.

• untied: App- and browser-based personal tax tool with strong bank linking (Open Banking), automated transaction categorisation, mileage tracking, ongoing visibility of your tax position, and direct HMRC filing. Excellent for sole traders, freelancers, landlords, and CIS workers who want year-round organisation and MTD readiness. High Trustpilot/app ratings for ease and support; fee reductions sometimes available via charities. Pricing often starts around £65–£130/year depending on features.

• Others worth noting: AbraTax (currently free/beta with full functionality, error-checking, and direct submission—good simple option while it lasts); SelfTax or similar budget tools (very low cost, basic wizard-style from ~£12+); Taxd (simple and well-reviewed for straightforward cases).

Full Accounting Software with Strong Tax Features

These handle invoicing, expenses, bank feeds, reporting, and tax submissions year-round—highly popular among UK freelancers and small businesses for reducing January stress. Many are MTD-ready for VAT and preparing for Income Tax.

• FreeAgent: Extremely popular with UK sole traders, freelancers, small limited companies, and landlords. Built specifically around UK tax rules—it calculates Self Assessment, supports direct HMRC filing for SA (a standout feature), VAT MTD, Corporation Tax estimates/accounts, payroll options, and more. Real-time tax timeline, excellent bank feeds/receipt capture, and strong support. Frequently praised in reviews and communities for making tax less daunting. Pricing typically from ~£19/month (sole traders) to ~£27–£33/month (partnerships/limited companies), excluding VAT, with intro discounts and often free via partner banks (e.g., Mettle, certain NatWest/RBS accounts). 30-day trial common.

• QuickBooks Online (Intuit): Very widely used globally and in the UK for its robustness, invoicing, expense tracking, reporting, multi-user options, and MTD VAT/Income Tax readiness. Good integrations and support. Self Assessment tools available (plans from roughly £10+/month or annual equivalents for sole trader tiers, higher for full features). Solid choice if you may grow or need more advanced tools.

• Xero: Hugely popular (especially among those working with accountants), excellent bank reconciliation, invoicing, inventory, and ecosystem of apps. Strong MTD VAT support and reporting that feeds into tax prep (direct SA filing more limited or agent-focused in some cases). Plans often start higher (~£15–£50+/month range depending on tier). Great for scalability.

• Sage Accounting / Sole Trader tools: Established UK brand with record-keeping, receipt scanning, invoicing, and Self Assessment preparation/support (some plans help generate forms or manage returns). Free basic sole trader options exist for simple needs; paid plans for more features. Good support and MTD capabilities.

• ANNA Money: Combines business banking, automated bookkeeping, and built-in Self Assessment/tax tools (live estimates, direct filing). Convenient all-in-one for freelancers and sole traders; filing sometimes free or discounted in the first year on paid plans. Strong for those wanting banking + tax automation.

Accountant-Assisted / Hybrid Services

• Taxfix (formerly TaxScouts): Very popular for people who want minimal DIY hassle. Answer questions/upload documents; a qualified UK accountant prepares, reviews, and files your return. Excellent Trustpilot scores (around 4.8/5 from thousands of reviews) for speed, ease, and professionalism. More affordable than traditional high-street accountants while providing expert oversight. Suitable for various complexity levels.

For Limited Companies / Corporation Tax

FreeAgent, QuickBooks, Xero, and Sage handle a lot. Specialist cheap options like TinyTax are popular for straightforward micro-entity CT600 + accounts filings (from ~£20/year dormant or ~£59+ trading). TaxCalc and professional suites suit more complex or multi-company needs.

Quick Buying Advice for UK Users

• Simple one-off SA return (few income sources) → GoSimpleTax, AbraTax (if free), untied, or HMRC free service. Or Taxfix for hands-off.
• Self-employed/freelancer/landlord needing bookkeeping → FreeAgent (often the community favourite), QuickBooks, Xero, or ANNA.
• MTD preparation (quarterly digital updates for Income Tax rolling out) → Prioritise recognised software with good digital record-keeping and bridging (FreeAgent, untied, GoSimpleTax, major accounting platforms, Clear Books free tiers in some cases). Check HMRC’s MTD software finder.
• Budget → Free/low-cost (HMRC, AbraTax, basic Sage/Clear Books, SelfTax) or bank-linked free FreeAgent.
• Complex or high value → TaxCalc, full accounting suite + accountant, or Taxfix.
• Check Trustpilot/recent reviews, trial periods, exact supported schedules (SA103 self-employment, SA105 property, SA108 capital gains, etc.), data security/GDPR, and cancellation flexibility. Prices exclude VAT and change—confirm on sites. Integrations with your bank or existing tools save time.

Many UK freelancers and sole traders successfully use FreeAgent or GoSimpleTax year after year. Start with your specific situation (income types, VAT-registered?, limited company?) and test free trials. If in doubt for complex affairs (e.g., foreign income, trusts, significant capital gains), consult a qualified accountant—the software is a tool, not a substitute for advice. Official HMRC deadlines and rules always take precedence.
