London and the South East tend to sit at the higher end. Smaller towns and online-only firms are often cheaper. Not always, though.
What Factors Affect How Much Does an Accountant Cost?
So, what actually affects the price you pay each month for an accountant? Several key factors play a big role in identifying accountant cost per month in the UK:
- Business Complexity: Larger businesses with more transactions or employees will cost more to manage.
- Your Annual Turnover: Higher revenue often means more complexity
- The “Mess” Factor: If your records are a disaster, the fee will be higher. Because the accountant has to spend hours playing detective.
- Accountant’s Expertise and Reputation: The experience and qualifications of your accountant will also affect the cost.
- Location: Accountants in major cities like London may charge higher fees than those in smaller towns or rural areas.
- Service Type: Basic stuff like simple bookkeeping costs less. Services that involve real strategy, like business advisory, detailed tax planning, or financial strategy, will cost you more.
- Volume of Work: If the number of transactions or documents that need to be managed is higher, the accountant cost per month in the UK will also be high.
How Much Does An Accountant Cost For A Small Business Per Month?
For more complex small businesses, especially fast-growing limited companies with a team of employees and high transaction volumes, the average accountant cost per month in the UK can range from £150 to £500 per month.
Small businesses with simple accounting needs, like bookkeeping and VAT returns, can expect to pay on the lower end of this scale. Whereas businesses requiring more comprehensive services like management accounting may find themselves at the higher end.
Here is a breakdown of typical accounting fees for small businesses:
| Service Type | Estimated Cost per Month |
| Basic Bookkeeping and Tax Filing | £50 – £150 |
| VAT Returns and Compliance | £20 – £80 |
| Monthly Management Accounts | £150 – £350 |
| Payroll Services | £20 – £100 |
| Full Business Advisory and Strategy | £500+ |
How Much Do Accountants Charge For Sole Traders?
If you are a sole trader, you are in luck. You will probably get the most affordable prices out there. Lots of accountants offer basic monthly packages specifically for freelancers. They usually start at around £60 to £100 a month.
This usually covers:
- Your annual Self Assessment tax return.
- Access to accounting software like Xero or QuickBooks.
- Basic advice on what expenses you can claim.
If you want them to do all your bookkeeping for you, be prepared to pay a bit more. Closer to the £150 per month mark.
How Much Do Accountants Charge for Tax Returns and Self-Assessment?
If you only need help once a year, you might opt for a one-off fee. For a straightforward Self Assessment tax return, fees usually range from £150 to £600.
For a basic return, fees are generally at the lower end of this range. Usually around £200-£350.
And if you have complex investments, capital gains, or foreign income, expect the price to increase. This is just because there are more forms to fill out and extra calculations for the accountant to double-check.
Is It Better to Pay Monthly or a One-Off Annual Fee?
For business owners with ongoing transactions, paying monthly is usually the more practical choice. One-off annual fees might seem simpler, but it often leads to a bill shock. Because you have to find a large sum of money all at once. In contrast, paying monthly spreads the cost, thus making your cash flow much easier to manage.
The biggest benefit of a monthly plan is the access. Instead of just talking to your accountant once a year when problems might already exist, you can ask questions whenever they pop up. This proactive way of working often saves you more money in taxes than the monthly fee costs you.
The only time a one-off annual fee makes more sense is if:
- Your finances are extremely simple: For example, you have one simple rental property and only need someone to file a basic tax return once a year.
- You are confident you will never need advice during the year: You handle all your bookkeeping perfectly and only need a professional signature at the end.
For pretty much everyone else, a monthly fixed fee gives you better value and way less stress.
Making Tax Digital and the Accountant Cost Per Month in the UK
The UK tax landscape has officially changed. As of April 2026, Making Tax Digital (MTD) for Income Tax is now mandatory for sole traders and landlords with an income over £50,000. The next phase will extend this requirement to those with an income over £30,000 starting in April 2027.

Accountants are super important for this. They will help you manage your digital records and ensure you are doing everything right. Your monthly accountant cost will likely cover this ongoing MTD compliance stuff.
However, if you haven’t transitioned yet or are preparing for the 2027 threshold, expect your accountant to charge a one-off fee to get your digital systems set up.

You won’t shave much off by haggling. You’ll shave more off by being organised. A few things that genuinely help:

- Ask for a fixed fee. No surprises, and it’s easier to budget.
What Are The Hidden Accountant Costs That People Forget?

None of these is a scam. They just catch people off guard because nobody mentioned them at the start.
Should You Hire an Accountant?
There are definitely some big perks of hiring an accountant. This includes saving yourself a ton of time and being able to make smart financial choices.
That said, hiring an accountant isn’t a requirement for every single person. If your finances are very straightforward and you feel totally fine handling the paperwork yourself, you might not actually need an accountant.

Online Accountant or Local Accountant?
