Contractor Accountant Fees (2026): A Complete Guide for UK Contractors
Pricing is usually one of the first things contractors want to know before hiring an accountant. And fair enough — you want to know what you are getting into before committing to a monthly fee. The good news is that contractor accountant fees in the UK are generally transparent, predictable and in most cases, well worth what you pay.
The typical monthly cost sits between £60 and £150 plus VAT, depending on the services included and the firm you choose. This article breaks down exactly what that money gets you, what to watch out for and how to decide whether the fee represents good value.

How Much Does a Contractor Accountant Cost in 2026?
Most specialist contractor accountants in the UK charge a fixed monthly fee. Here is what you can generally expect across different price points:
| Package Level | Monthly Fee (ex VAT) | What's Typically Included |
|---|---|---|
| Entry level | £60 – £80 | Annual accounts, corporation tax return, basic HMRC support |
| Mid range | £80 – £120 | All of the above plus Self Assessment, payroll, VAT returns, bookkeeping software |
| Comprehensive | £120 – £150 | Full service including IR35 support, dedicated accountant, tax planning advice |
One thing many contractors miss when comparing prices: VAT is charged on top by most accountancy firms. So a fee advertised at £100 per month will actually cost £120 once VAT is added. Always check whether the price quoted is inclusive or exclusive of VAT before you sign up.

What Pricing Models Do Contractor Accountants Use in the UK?
Before comparing quotes, it helps to understand how contractor accountants structure their pricing. Price is only one factor when choosing an accountant. It's also worth considering their experience with contractors, the level of support they provide and the services included in their package. Read our guide on how to choose a contractor accountant to understand what to look for before making your decision.
Fixed monthly fee is by far the most common model among specialist contractor accountants. You pay the same amount each month and know exactly what is covered. There are no surprise invoices at year end, which makes budgeting straightforward. For most contractors, this is the model that works best.
Hourly rate is less common in the contractor accounting space but does still exist, particularly among general accountants who take on contractor clients occasionally. Rates typically sit between £50 and £150 per hour. The problem with hourly billing is that costs can quickly become unpredictable, especially during busier periods like the Self Assessment deadline in January.
One-off fees apply to specific tasks that fall outside a standard package — things like company formation, IR35 contract reviews or mortgage reference letters. Some firms include these in their monthly fee; others charge separately. This is worth clarifying before you commit to any package.
For the vast majority of contractors, a fixed monthly fee from a specialist firm is the most practical and cost-effective option.
What Does a Contractor Accountant Fee Typically Include?
A mid-range package from a specialist contractor accountant will usually cover the following:
- Annual accounts prepared and filed with Companies House
- Corporation tax return submitted to HMRC
- Self Assessment personal tax return for you as a director
- Director payroll set up and run each month
- VAT registration and quarterly VAT returns
- Access to cloud bookkeeping softwaresuch as FreeAgent or Xero
- Companies House confirmation statement filed annually
- Ongoing support for HMRC queries and general tax questions
- Salary and dividend planning advice
This covers the core of what most limited company contractors need to stay compliant and run their finances efficiently throughout the year.

What Factors Affect the Cost of a Contractor Accountant in the UK?
Two contractors paying different monthly fees are not necessarily getting a better or worse deal, the cost difference often comes down to legitimate variables:
- Business structure — limited company contractors generally pay more than sole traders due to the additional complexity involved
- IR35 support — packages that include ongoing IR35 advice and contract reviews naturally cost more than basic compliance-only packages
- Level of support — a dedicated accountant who knows your business and is available by phone costs more than a shared team you contact via a ticketing system
- Online versus local — online-only firms tend to be cheaper due to lower overheads; local firms with office space and face-to-face availability typically charge a little more
- Transaction volume — if your business has high volumes of expenses, invoices or payroll entries, some firms will charge more to reflect the extra bookkeeping work involved
Understanding which of these factors applies to your situation helps you compare quotes on a fair and equal basis.
Are Contractor Accountant Fees Tax Deductible?
Yes — and this is something many contractors do not fully appreciate when they first look at the monthly cost. Accountancy fees are a legitimate and allowable business expense under HMRC's guidelines on allowable expenses, which means they are deducted from your company's profits before corporation tax is calculated.
In practice, this means the real cost of your accountant is lower than the headline figure. If your limited company pays corporation tax at 19%, a monthly fee of £100 effectively costs you around £81 after tax relief. At higher rates of corporation tax, the saving is even greater.
This does not make the fee free but it does mean that when you are weighing up the cost against the value, the net figure is meaningfully lower than what appears on your bank statement each month.
Is a Contractor Accountant Worth the Cost?
For the vast majority of limited company contractors, the answer is yes — and by a significant margin.
Consider what a specialist contractor accountant actually delivers. The right salary and dividend structure alone can save most contractors between £2,000 and £5,000 per year compared to drawing everything as salary. Identifying all allowable business expenses, equipment, professional subscriptions, home office costs, travel, adds further savings. Pension contributions made through the company reduce your corporation tax bill on top of that.
Then there is the protection side. HMRC fines for late filing start at £100 and escalate quickly. An IR35 mistake can result in years of back tax and National Insurance being demanded at once. A missed VAT registration threshold means back-dated VAT owed from the point you should have registered.
When you look at the full picture, the monthly fee is not really a cost at all, it is what you pay to avoid much larger losses while keeping more of what you earn.
Not all accounting firms for contractors offer the same level of expertise or support. Comparing services, contractor experience and fixed-fee packages can help you choose an accountant that delivers long-term value rather than simply the lowest monthly cost.
