What if your accountant cost less than a weekly food shop and never asked you to leave the house? For many UK owners, that’s already real.
Online accountants UK-wide now handle bookkeeping, VAT, payroll and year-end filings from a laptop, usually at a published price. The catch is that the choices have multiplied, and not every package covers what you think it does.
This guide ranks ten of the strongest options for 2026, explains what each costs, and shows you how to choose without regretting it six months later.
Why Are Small Businesses Moving Online?
In the past, getting an accountant involved meant booking an appointment, receiving a quote, and hoping the total would be the same at the end. This is no longer true because most companies now display their pricing and link their services to your bank accounts and cloud accounting tools. There are two reasons this is happening so quickly. The first is that cloud accounting is now the norm, and the other is HMRC’s Making Tax Digital guidelines, which now cover Income Tax starting April 2026. This is just one reason for you to move away from spreadsheets. Remember that when reading this article.
How We Picked These Ten?
I looked at published 2026 pricing, what each package covers, software support, range of services and who each firm suits best. Prices change, and many firms adjust quotes for turnover and transaction volume, so treat every figure as a starting point.
Here’s what I weighed:
- Clear, published pricing with no surprise add-ons
- Breadth of services under one roof
- Support for Xero, QuickBooks, FreeAgent or in-house software
- Making Tax Digital readiness
- Quality of support, whether human, app-based or both
- Value for money at different business sizes

1. GTC Accountants: Our Top Pick
GTC earns the first spot for a simple reason: it combines some of the lowest published entry prices with an unusually wide service list. You aren’t forced into one narrow category either. There are separate packages for sole traders, limited companies, startups, freelancers and partnerships.
Published starting prices:
| Package | From (per month) |
| Startups | £29 |
| Freelancers | £29 |
| Partnerships | £34 |
| Sole traders | £39 |
| Limited companies | £49 |
Beyond core compliance, GTC covers a lot of ground:
- Annual accounts, tax returns and Self Assessment
- VAT returns, bookkeeping and payroll
- Management accounts, cash-flow forecasting, budgeting and KPI reporting
- Xero, QuickBooks UK and FreeAgent setup and training
- Incorporation advice, company formation and Making Tax Digital compliance
- Property accounting, including buy-to-let accounts, capital gains tax and property SPVs
- Tax planning and support with HMRC, VAT and COP9 investigations
That last group matters more than people realise. Most budget online firms stop at filing. Having investigation support and tax planning under the same roof means you won’t need to hunt for a specialist if HMRC sends an awkward letter.
- Best for: Small businesses that want low monthly pricing now but room to grow into advisory work later.
- Watch out for: Prices shown are “from” figures, so confirm exactly what your tier includes, such as VAT or payroll, before you commit.
2. Crunch
Crunch is one of the most recognizable names in the field. They offer an accounting program along with human assistance from accountants.
- Pricing: Entry-level software tiers start at roughly £10 a month plus VAT. Full limited company packages sit nearer £75 a month.
- Best for: Freelancers and startups who want software and advice from one provider.
- Watch out for: Prices climb as you add payroll, VAT and extra support.
3. Mazuma
Mazuma has a reputation for offering fixed rates along with an accommodating, freelance-oriented philosophy. It serves sole proprietors, contractors, and limited companies.
- Pricing: Packages start from around £32–£35 a month, rising with complexity.
- Best for: Contractors and freelancers who want predictable costs.
- Watch out for: Check which extras, such as payroll or VAT returns, sit outside the base price.
4. GoForma
GoForma mainly handles firm incorporation and accounting after that. It’s a good option if you are just getting started.
Pricing: Fixed monthly packages, depending on your company’s performance.
- Best for: New directors seeking combined setup and accounting services.
- Watch out for: Compare package contents to non-package contents.
5. Sleek
Sleek is all about the digital-first approach and is ideal for founders who enjoy using dashboards.
- Pricing: Fixed packages that scale with your needs.
- Best for: Tech-minded startups and small teams.
- Watch out for: Clarify how much direct accountant contact you get on lower tiers.
6. The Accountancy Partnership
This firm prices the accountancy relationship on its own rather than bundling software. That suits you if you already have a bookkeeping tool you like.
- Pricing: Fixed annual fees, with published ranges reaching around £599 a year at the top end of the packages surveyed.
- Best for: Sole traders and small limited companies who already have software.
- Watch out for: Software is usually separate, so factor that in.
7. More Than Accountants
Like the firm above, More Than Accountants keeps pricing simple and separate from software. You pay for the accountancy and nothing else.
- Pricing: Annual fixed-fee structure.
- Best for: Owners who prefer one yearly number to a monthly subscription.
- Watch out for: Confirm whether VAT is included in the quoted figure.
8. TaxAssist Accountants
TaxAssist is a hybrid: a UK-wide network with local offices and online service. It’s useful if you like the option of an occasional face-to-face chat.
- Pricing: Roughly £30–£70 a month, depending on location and service.
- Best for: Sole traders who want local support without losing digital convenience.
- Watch out for: Software and service can differ between local offices.
9. MyIVA
MyIVA deals with corporate tax, Self Assessment, and overall support for small businesses, particularly personal service.
- Pricing: Tailored to your business size and transaction volume.
- Best for: Owners who want someone to explain things, not just file them.
- Watch out for: Ask for a written quote so you know exactly what’s included.
10. Zmartly
Zmartly provides an assigned, qualified accountant and cloud-based software. The human element is what sets it apart.
- Pricing: Fixed monthly fees based on structure and complexity.
- Best for: Directors who want a real person they can message.
- Watch out for: Ask about response times during busy filing periods.
What Does It Actually Cost?
Let’s start with numbers because that’s all that most people care about. Published guidelines for accountancy for small businesses set the monthly cost from £50 to £500, but that’s a broad range since “small business” can mean anyone from a part-time freelancer to a ten-person business.
A more realistic picture:
| Business Type | Typical Monthly Cost |
| Sole trader (accounts and tax) | £30–£80 |
| Limited company (core accounts and tax) | £80–£250 |
| Budget online limited company package | £60–£90 |
| Mid-range online accountant (contractors) | £100–£150 |
For single-use purposes, a self-assessment tax return usually costs between £150 and £300, and annual accounts with tax normally cost between £300 and £600. If you are searching for reasonable monthly fees of an accountant in the UK, then small businesses that charge monthly will normally charge from £80 to £250. You should note that some companies, like GTC, even offer entry-level fees which are much lower than that.
Choosing an Online Accountant for a Limited Company
Directors have a lot more to think about than sole traders: annual accounts, the Confirmation Statement, corporation tax, perhaps VAT, and PAYE if you are paying yourself.
A good online accountant for limited company owners should cover:
- Statutory accounts and the corporation tax return
- Director’s salary and dividend guidance
- VAT registration and returns where needed
- Payroll and pension auto-enrolment
- Proactive tax-saving advice, not just filing
Find out whether a named individual will actually handle your account. Some companies employ a named accountant to handle your account, while other companies use a support group.
Finding Affordable Accountants for Small Business
Cheap isn’t the goal. Good value is. When you’re hunting for affordable accountants for small business needs, the lowest quote can end up costing more once extras appear.
Try this checklist before you commit:
- Is VAT included in the price shown?
- Are bookkeeping, payroll and VAT returns bundled or extra?
- Is cloud software included, or billed separately?
- Can you leave without a long contract?
- What happens if HMRC sends a letter or opens an inquiry?
On a £45 monthly fee, a VAT ambiguity alone can add over £100 a year. The small print matters.
Why a Fixed Fee Accountant Is Worth Considering?
Under the fixed-fee accounting approach, you have one figure you can plan on. No time will be logged against you when you have a question, and there won’t be any unpleasant surprises in January. This model is most suitable when your requirements are predictable. For instances where you may need a lot of ad-hoc consulting, such as structuring and complicated taxation, you can go with a fixed-fee structure, with consulting charged separately.
Online vs Traditional Accountants
| Factor | Online Accountant | Traditional Accountant |
| Pricing | Published, fixed | Often quote-based or hourly |
| Software | Usually included or integrated | Varies widely |
| Meetings | Video, phone or chat | In person |
| Speed | Fast digital turnaround | Can be slower |
| Local knowledge | Less personal | Often stronger |
| Best for | Startups, freelancers, simple companies | Complex or highly local businesses |
Mistakes to Avoid When Hiring
The same slip-ups come up again and again:
- Picking on price alone: The cheapest plan often excludes the thing you need most.
- Ignoring qualifications: Check for ACCA, ICAEW or an equivalent body.
- Skipping the software question: Switching tools later is a hassle.
- Forgetting Making Tax Digital: Make sure your accountant is ready for the 2026 changes.
- Not asking about support: Find out how quickly they reply before you need them urgently.
How to Choose in Five Steps?
- Work out your business type: sole trader, limited company, partnership or freelancer.
- List what you need: bookkeeping, VAT, payroll, tax advice.
- Set a realistic monthly or annual budget.
- Shortlist three firms and request written quotes.
- Test their responsiveness with a simple question before you sign.
If a firm takes days to answer a pre-sales question, imagine how it’ll feel when you’ve got a deadline.
Final Thoughts
There will never be anything better than something that simply makes sense. This is something that will fit your company, will have reasonable pricing, and most importantly, will respond when you call them. GTC Accountants stands out from the rest because it offers low starting prices for small businesses and supports growth as you grow. However, remember to get estimates from at least two or three accounting companies. Your accountant is supposed to be a relief, not just one more problem.
FAQ
Q. What are the best online accountants in the UK for small businesses?
A. Our recommendation for the best choice is GTC Accountants, considering low starting fees and extensive services ranging from basic bookkeeping up to tax planning. Crunch and Mazuma are favored by freelance professionals, GoForma is good for newly appointed directors, while The Accountancy Partnership and More Than Accountants are better choices for individuals looking for an annual fixed fee.
Q. How much does an online accountant cost per month in the UK?
A. Sole traders usually pay £30 to £80 per month. Limited companies typically cost between £80 and £250, though some cheap online packages cost less. Some firms will quote entry prices of between £29 and £49 a month, but extras such as payroll, VAT returns and advisory time can bring the figure up, so always check what is included.
Q. Are fixed-fee accountants worth it for a sole trader?
A. Yes, usually. For the work of a sole trader, like bookkeeping and Self Assessment, the work is pretty predictable, so a fixed fee helps with budgeting. If your finances are simple, you probably don’t need more. If you grow, register for VAT or hire staff, check the package to ensure you are not under-covered.
Q. Online accountant vs traditional accountant: which is better for a startup?
A. For most startups, an online accountant is a better place to start. You’ve got cloud software, fast digital support, and transparent pricing, often at a lower cost. A traditional accountant may make more sense if you want face-to-face guidance or have an unusually complex structure. Many founders start online and bring in specialist advice at a later stage.
Q. Is it safe to use an online accountant?
A. Yes, provided the firm belongs to a recognized professional body and holds professional indemnity insurance. Ask about data security and who can access your records before handing anything over.
