Filing a self-assessment tax return can feel complicated, especially when you’re juggling a busy schedule. Whether you’re a Black Cab driver, a landlord, or a CIS subcontractor, understanding the costs involved in hiring an accountant for your self-assessment is essential. It helps you budget properly and ensures you get the right support without surprises.
In this post, I’ll walk you through the key points about self-assessment accounting costs. I’ll explain what influences fees, typical price ranges, and how to choose the right accountant for your needs. My goal is to make this topic clear and straightforward so you can make informed decisions.
What Influences Self-Assessment Accounting Costs?
The cost of hiring an accountant for your self-assessment depends on several factors. Knowing these can help you understand why prices vary and what you should expect to pay.
Complexity of Your Tax Return
If your financial situation is simple, such as having only one source of income, your accountant’s work will be quicker and less costly. However, if you have multiple income streams, rental properties, or expenses to claim, the accountant will spend more time reviewing your documents and ensuring everything is accurate.
Volume of Work Required
Some clients need just a basic tax return, while others require additional services like bookkeeping, tax planning, or advice on allowable expenses. The more services you need, the higher the cost.
Experience and Location of the Accountant
Accountants with more experience or specialist knowledge in your industry may charge higher fees. Also, accountants based in larger cities or affluent areas often have higher rates than those in smaller towns.
Timing and Deadlines
If you leave your tax return until the last minute, some accountants may charge extra for urgent work. Planning ahead can save you money and reduce stress.
Use of Technology
Some accountants use software that streamlines the process, which can reduce costs. Others may still rely on manual methods, which can take longer and cost more.

Understanding Self-Assessment Accounting Costs in Detail
When budgeting for an accountant, it’s helpful to know the typical cost ranges and what you get for your money. Here’s a breakdown of common fees and services.
Basic Self-Assessment Tax Return
For a straightforward tax return, fees usually range from £100 to £300. This covers the preparation and submission of your return to HMRC. It’s suitable if you have one or two income sources and minimal expenses.
More Complex Returns
If you have rental income, are a CIS subcontractor, or run a limited company, expect to pay more. Fees can range from £300 to £700 or higher depending on complexity. This includes:
Detailed review of income and expenses
Advice on allowable deductions
Assistance with CIS tax deductions or landlord-specific rules
Additional Services
Some accountants offer packages that include bookkeeping, payroll, or tax planning. These services can add £200 to £1,000+ annually depending on your needs.
Fixed Fees vs Hourly Rates
Many accountants offer fixed fees for self-assessment returns, which helps you know the cost upfront. Others charge hourly, typically between £50 and £150 per hour. Fixed fees are often better for budgeting.
Discounts and Packages
If you use the same accountant for multiple services or years, you might get a discount. Some firms offer packages tailored to specific industries like Black Cab drivers or landlords.
How much do accountants usually charge for tax returns?
Understanding the typical charges for tax returns helps you compare quotes and avoid overpaying. Here’s what you can expect:
Simple tax returns: £100 to £300
Landlords with rental income: £300 to £600
CIS subcontractors: £350 to £700
Limited companies: £500 to £1,200+
These figures are averages and can vary based on location and accountant expertise. Always ask for a clear quote before committing.

How to Choose the Right Accountant for Your Self-Assessment
Finding the right accountant is about more than just price. Here are some tips to help you pick the best fit:
Look for Industry Experience
Choose an accountant familiar with your profession. For example, Black Cab drivers and CIS subcontractors have specific tax rules. An accountant who understands these can save you money and hassle.
Check Qualifications and Reviews
Make sure your accountant is qualified and registered with a professional body. Reading client reviews can also give you insight into their reliability and service quality.
Ask About Services Included
Clarify what’s included in the fee. Does it cover advice, submission, and support if HMRC has questions? Knowing this upfront avoids unexpected charges.
Consider Communication Style
You want an accountant who explains things clearly and responds promptly. Good communication makes the process smoother and less stressful.
Get Multiple Quotes
Don’t settle for the first quote. Comparing a few accountants helps you find the best value for your money.
Tips to Keep Your Self-Assessment Accounting Costs Manageable
