The Ultimate Guide to Accountant Costs in 2026: Compare Accountants for Small Business and Save

  • Jul 13

Let’s be honest: when you’re running a small business, every penny counts. Whether you’re a freelance graphic designer in London or a growing construction firm in Surrey, your biggest question when looking for financial help is usually, "How much is this going to cost me?"

As we move through 2026, the accounting world has changed. With the full rollout of various Making Tax Digital (MTD) phases and the rise of AI-driven bookkeeping, the way accountants charge: and what they provide: has shifted.

If you want to find an accountant UK businesses trust, you need to know what a fair price looks like today. In this guide, we’ll break down the latest costs so you can compare accountant services with confidence and keep more of your hard-earned cash.

Why Accountant Costs Vary So Much

Before we dive into the numbers, it’s important to understand why one quote might be £50 a month and another is £500. Accounting isn't a one-size-fits-all service. The price you pay is usually a cocktail of three things:

  1. Your Business Structure: A sole trader has much simpler filing requirements than a limited company.

  2. Your Turnover: Higher turnover usually means more transactions, which means more work for the accountant.

  3. The Level of Service: Do you just need a Self-Assessment accountant once a year, or do you need full-service bookkeeping and payroll?

Average Accountant Fees in 2026: The Breakdown

Pricing has stabilised slightly in 2026 as firms have fully integrated new automation tools, but the cost of living and professional insurance have kept base rates firm. Here is what you can expect to pay on average:

Sole Traders (Self-Employed)

For most sole traders, costs are relatively low. If you handle your own day-to-day records and just need someone to check the boxes at the end of the year, you’re looking at:

  • Self-Assessment Return Only: £150 – £400 per year.

  • Basic Monthly Package: £50 – £100 per month (includes basic software access and year-end filing).

Limited Companies

If you've stepped up to a Limited Company, the workload for an accountant increases significantly due to Corporation Tax and Companies House filings.

  • Dormant Company Filing: £100 – £200 per year.

  • Small Limited Company (Solo Director): £100 – £180 per month.

  • Active Small Business (with VAT/Payroll): £150 – £350 per month.

One-Off Fees & Hourly Rates

Sometimes you don't need a monthly plan. You might just need a consultation or a specific task finished.

  • Hourly Rates: Typically range from £50 to £150 per hour depending on the firm’s seniority and location.

  • VAT Registration & Filing: If you need a VAT accountant, expect to pay around £100–£200 per quarter for the filing itself if you aren't on a monthly plan.

Online Accountant vs. High Street Firm: Which Is Better for Your Budget?

This is the classic debate for anyone trying to find an accountant for small business UK wide.

Online Accountants are usually cheaper. They use cloud software to automate the boring bits, allowing them to charge lower fixed fees. This is perfect if you’re tech-savvy and don't feel the need to sit across a desk from someone.

High Street Firms are often more expensive because they have higher overheads (like that nice office in the town centre). However, they offer a personal touch. If you have a complex business or prefer face-to-face advice, the extra £50–£100 a month might be worth the peace of mind.

The Hidden Costs You Haven't Thought Of

When you compare accountants for small business, don't just look at the headline monthly fee. Ask about these potential "extras" that can sneak up on you:

  • Software Subscriptions: Many accountants require you to use software like Xero, QuickBooks, or FreeAgent. Some include this in their fee; others charge you an extra £20–£40 a month for it.

  • Payroll Fees: If you start hiring staff, most accountants charge a "per payslip" fee, usually between £5 and £15 per employee.

  • MTD Compliance: With "Making Tax Digital" now a standard, ensure your accountant isn't charging an "MTD Surcharge" for filing digitally: this should be part of their standard service in 2026!

  • Reference Letters: Need a letter for a mortgage or a visa? Some firms charge £50–£100 per letter.

How to Save Money on Your Accounting Fees

You don't always have to pay the top-tier price to get top-tier service. Here are three quick ways to slash your accounting bill:

  1. Do Your Own Bookkeeping: If you hand your accountant a shoebox of crumpled receipts, they will charge you by the hour to sort them. If you use an app to scan receipts as you go, you’ll save a fortune.

  2. Don't Wait Until January: If you send your tax info to your accountant on January 20th, don't be surprised if they add a "priority" fee. Send it in May or June, and you might even get a discount.

  3. Compare Services Regularly: Loyalty is great, but the market changes. Use a service like Accountant Search to see what other firms are offering. You might find a better deal that includes more features for a lower price.

Why Comparing is the Key to SME Growth

Your accountant shouldn't just be a "cost": they should be an investment. A good one will save you more in tax than they charge in fees. However, overpaying for basic compliance can drain the capital you need to grow your business.

When you compare accountants for small business, you aren't just looking for the cheapest price; you're looking for the best value. Whether you need accountants in London or specialist tax advice in Surrey, taking ten minutes to compare quotes can save you thousands over the life of your business.

A happy group of small business owners

Final Thoughts

The average small business in the UK can expect to pay anywhere from £600 to £3,000 a year for accounting services in 2026. The key is to match the service level to your actual needs. Don't pay for a "Gold" package if you're a simple sole trader, but don't cut corners if you're a scaling limited company.
