Filing a self-assessment tax return can feel overwhelming, especially when you’re unsure about the costs involved. Whether you’re a Black Cab driver, landlord, CIS subcontractor, or running a limited company, understanding the expenses related to self-assessment filing is crucial. It helps you budget properly and avoid surprises during tax season.


In this post, I’ll walk you through the typical costs you might face when filing your self-assessment tax return. I’ll also explain what influences these costs and offer practical tips to keep your expenses manageable.


What Are Self-Assessment Accountant Costs?


When you hire an accountant to handle your self-assessment tax return, you’re paying for their expertise, time, and the peace of mind that your tax affairs are in order. The costs can vary widely depending on several factors:


  • Complexity of your tax situation: The more complicated your finances, the more time an accountant will spend on your return.

  • Type of income: Income from rental properties, CIS subcontracting, or limited companies often requires more detailed work.

  • Additional services: Some accountants offer bookkeeping, tax planning, or advice on tax-saving strategies, which can add to the cost.

  • Location and reputation: Accountants in different regions or with specialized experience may charge differently.


For example, a Black Cab driver with straightforward income and expenses might pay less than a landlord with multiple rental properties and complex deductions.


Understanding these factors helps you choose the right accountant and avoid unexpected fees.

Typical Self-Assessment Accountant Costs Explained


In the UK, self-assessment accountant costs usually fall into a few common price ranges. Here’s a rough guide to what you might expect:


  • Basic tax return: £100 to £300

This covers simple returns with straightforward income sources, such as employed income or a single self-employed trade.


  • Self-employed or CIS subcontractors: £200 to £500

If you’re a CIS subcontractor or self-employed, your return will include business income and expenses, which require more detailed work.


  • Landlords: £300 to £600

Landlords often have rental income, allowable expenses, and possibly capital gains to report, increasing the complexity.


  • Limited companies: £500 to £1,000+

Limited company accounts and tax returns are more complex and usually require additional services like corporation tax filing and bookkeeping.


These figures are approximate and can vary based on your accountant’s experience and the services you need.


How much do accountants usually charge for tax returns?


When considering how much to pay, it’s important to understand what you’re getting for your money. Accountants typically charge based on:


  • Time spent: They may charge an hourly rate or a fixed fee.

  • Complexity: More complex returns take longer and cost more.

  • Additional advice: Some accountants include tax planning or bookkeeping in their fees.


For example, an accountant might charge £150 for a simple self-assessment return but £400 for a landlord with multiple properties. If you need ongoing bookkeeping or tax advice, expect to pay more.

Tips to Manage and Reduce Your Self-Assessment Accountant Costs


You don’t have to accept high fees without question. Here are some practical ways to keep your accountant costs reasonable:


  1. Organize your records

    Keep your income and expense records well-organized throughout the year. This saves your accountant time and reduces fees.


  2. Be clear about your needs

    Tell your accountant exactly what services you require. Avoid paying for extras you don’t need.


  3. Shop around

    Get quotes from several accountants. Compare their fees and services before making a decision.


  4. Use online accounting tools

    Some accountants offer discounts if you use online bookkeeping software, which can streamline the process.


  5. Ask about fixed fees

    Fixed fees give you certainty about costs and help avoid surprises.


  6. Plan ahead

    Don’t leave your tax return to the last minute. Early preparation can reduce rush fees.


By following these tips, you can make the most of your accountant’s expertise without overspending.


Why Hiring an Accountant Can Save You Money in the Long Run


It might seem tempting to file your self-assessment tax return yourself to save money. However, hiring an accountant can actually save you money over time. Here’s why:


  • Maximize allowable expenses

Accountants know which expenses you can claim, helping you reduce your tax bill.


  • Avoid penalties

Late or incorrect filings can lead to fines. An accountant ensures your return is accurate and on time.


  • Get expert advice

Accountants can advise on tax planning strategies tailored to your situation, such as pension contributions or capital allowances.


  • Save time and stress

Managing your own tax return can be time-consuming and stressful. An accountant handles the paperwork, letting you focus on your business.


For Black Cab drivers, landlords, and CIS subcontractors, these benefits are especially valuable. The right accountant becomes a trusted partner in managing your finances.


Planning Your Budget for Self-Assessment Filing


When budgeting for your self-assessment filing, consider the following:


  • Estimate your accountant’s fee based on your situation.

  • Include additional costs such as bookkeeping or tax advice.

  • Set aside funds for potential tax payments after your return is filed.

  • Review your budget annually as your business or income changes.


Having a clear budget helps you avoid last-minute financial pressure and keeps your tax affairs on track.



Understanding the costs involved in self-assessment filing is the first step toward managing your finances effectively. By knowing what to expect and how to prepare, you can make informed decisions and work confidently with your accountant. This approach ensures your tax return is accurate, timely, and cost-effective.
