Confused about what you should pay for a Self Assessment tax return in the UK? Every year, thousands of business owners and landlords ask: how much do accountants charge for Self Assessment? With HMRC penalties rising, it’s crucial to understand accountant fees and what you get for your money. This guide reveals up-to-date UK prices, factors affecting costs, and tips to get the best value from your accountant. Written and reviewed by ICAEW and AAT qualified accountants at Tax Return Accountants, you’ll find practical examples, real fee breakdowns, and insights you won’t see elsewhere.

How Much Do Accountants Charge for Self Assessment UK?

This article explains typical UK accountant fees for Self Assessment, what affects the price, and how to ensure you get value for money—whether you’re a sole trader, landlord, company director, or employee.

How Much Do Accountants Charge for Self Assessment UK? [2026/27 & 2027/28 Fee Ranges]

Over 800,000 HMRC late filing penalties were issued in 2024/25 alone (source: GOV.UK). This makes understanding accountant charges for Self Assessment in the UK more important than ever. For the 2026/27 and 2027/28 tax years, most clients pay between £150 and £500 for a typical return, with VAT on top. The lower end (£100–£250) applies to employees or pensioners with straightforward income, while sole traders, landlords, and directors with more complex affairs often see fees from £250 to £600 or more. These figures reflect recent market surveys and our own client data at Tax Return Accountants.

What’s included? For most, the fee covers preparing the tax return, submitting to HMRC, basic advice, and answering standard queries. Extras—such as Capital Gains Tax calculations, dealing with multiple properties, or responding to HMRC enquiries—may cost more. It’s crucial to clarify up front what’s covered in your quote. Some accountants, especially in London, charge 20–30% more than regional averages, driven by higher demand and overheads.

For example, a Leicester-based client with a single income source and good records typically pays £180–£220, while a London landlord with three properties might face a bill of £450–£600. At Tax Return Accountants, our average fee for a sole trader with moderate complexity in 2025/26 was £320, which included full HMRC submission and advice on allowable claims. Always check if your accountant is ICAEW or AAT regulated for added assurance (GOV.UK).

Average UK Self Assessment Accountant Fees

The average cost of accountant for tax return UK is £150–£500 for most individuals, with higher fees for directors, landlords, or those with investments and multiple income streams. These figures are based on the latest ICAEW and AAT surveys and reflect both regional and national averages.

Typical Inclusions & Exclusions

Most accountants include full preparation, online filing, and basic HMRC correspondence in their fee. However, services such as rental property schedules, capital gains calculations, or HMRC enquiry support may be charged separately. Always clarify this before agreeing to a fee.

Factors Affecting Price

The main drivers are the complexity of your affairs, how well your information is organised, and your location. For example, a client in Manchester with multiple investments and poor paperwork may pay £200 more than a Nottingham client with similar income but well-organised records. Last updated: June 2026.

What Affects Self Assessment Accountant Fees? (And How to Save Money)

Fee differences are not random—your actions directly impact the price you pay.

• Multiple income types (self-employment, property, dividends) increase the work required and the cost.
• Bringing in well-organised summaries and receipts can lower your fee by up to 20% compared to handing over a “shoebox” of paperwork.
• Last-minute submissions (close to the 31 January deadline) often attract higher charges due to rush work and overtime.
• Location matters: accountant charges for sole traders UK-wide are typically 20–30% higher in central London than in Leicester, Birmingham, or Nottingham.
• Special cases—such as capital gains, foreign income, or multiple properties—add to the base price.

To help you compare, here’s a practical fee comparison:

For example, we recently worked with a Nottingham landlord who initially paid £100 more each year by using an accountant who charged per property but didn’t claim all allowable deductions. After switching to our service, their total bill dropped by £120, and their tax due fell by £300 due to more thorough claims.

To keep costs down, always provide clear income and expense summaries, avoid last-minute submissions, and ask for a written breakdown of what’s included. For more on our transparent approach, see our Accountant Pricing page.

DIY vs Professional: Is Paying for a Tax Accountant Worth It?

Is it really cheaper to do your own tax return, or does a professional save you money in the end?

Most people believe that doing their own tax return always saves money. Actually, research from HM Revenue & Customs (HMRC) shows that over 800,000 late filing penalties were issued in 2024/25, with many errors arising from missed deadlines, incorrect claims, and not understanding new reliefs. If you’re a sole trader, landlord, or have multiple income sources, a professional often saves more than their fee by spotting missed claims and keeping you penalty-free.

Picture a Birmingham freelancer who filed their own return in 2025/26. They missed the £1,000 trading allowance and underclaimed business mileage, resulting in £320 extra tax—and a £100 late penalty when they misunderstood the 31 January deadline. After switching to a regulated accountant, they saved £420 in tax and avoided all penalties the following year, for a fee of £250.

HMRC penalties for mistakes are harsh: £100 for missing the deadline, then £10 per day after three months (up to £900), plus 5% of tax due (or £300, whichever is greater) at six and twelve months, and interest on unpaid tax (GOV.UK). For more detail, see our Self Assessment Service.

What most guides fail to mention: A regulated accountant can also represent you if HMRC launches an enquiry, saving you hours of stress and potentially thousands in back taxes and penalties.

Self Assessment Fees for Sole Traders, Landlords, and Limited Companies (By Client Type)

Imagine a Leicester landlord with three properties who previously filed their own tax return. They missed several deductible costs and paid a £100 late penalty. After switching to Tax Return Accountants, they paid a £400 fee, but their tax bill dropped by £800 and they avoided all penalties—a net gain of £400 and much less stress.

• Sole trader accountant fees UK: £150–£500 for most, depending on business size and how well expenses are documented. More complex businesses (multiple trades, CIS, or international clients) may pay £400–£700.
• Accountant fees for landlords UK: £150–£600, with each additional property adding £30–£50 to the fee. Multi-property landlords or those with capital gains calculations may see bills of £600–£900.
• Limited company self assessment accountant cost: Director returns are typically £200–£800, especially if you have dividends, benefits, or overseas income. This is in addition to company accounts and Corporation Tax filing (see our Limited Company Accountants service).
• Accountant charges for sole traders UK: If you have both self-employment and property income, expect to pay at the higher end of the range, especially if your records are not well organised.
• Freelance self assessment tax help UK: Freelancers with multiple clients, foreign earnings, or digital income streams (e.g., ecommerce) may pay £250–£600 depending on complexity.

For landlords, it’s important to note that each property increases the fee, but also the potential tax savings—especially if you use an accountant who understands mortgage interest relief and capital allowances. For more on landlord support, see our Landlord Accountants page.

Industry Insights: Contractor, Freelancer, Healthcare, Construction & More

Contractor and freelancer accountant fees in the UK range from £200 to £600, with IR35 status and sector complexity as key drivers (source: GOV.UK, IR35 guidance). If you’re a contractor, freelancer, or work in sectors like healthcare, construction, ecommerce, or as a taxi driver, you face unique challenges. Industry-specific rules (like CIS for construction or Making Tax Digital for landlords) can increase both the work and the fee.

For example, a Manchester contractor working through a limited company recently paid £350 for a tax return with IR35 review included. This compared to £220 for a freelancer with only UK clients and no IR35 risk. Healthcare professionals and taxi drivers often benefit from specialist accountants who understand sector deductions (e.g., uniform cleaning, vehicle costs).

• Contractor accountant fees UK: £200–£600+ (IR35 reviews, multiple contracts)
• Freelance self assessment tax help UK: £200–£500+ (multiple clients, digital income)
• Healthcare accountant fees: £180–£450 (NHS, locum, private practice)
• Construction accountant fees: £200–£550 (CIS, subcontractors, materials)
• Ecommerce accountant fees: £220–£600 (platform income, cross-border VAT)
• Taxi driver accountant fees: £150–£400 (vehicle expenses, mileage claims)

What most clients don’t realise is that choosing an accountant with sector experience can save far more than it costs. For instance, a construction client in Nottingham saved £700 in tax after their accountant identified missed CIS deductions—more than double the fee paid.

Accountant Fees for Software Support: Xero, QuickBooks, FreeAgent & Sage

Accountants with expertise in Xero, QuickBooks, FreeAgent, or Sage may charge a premium—but the right software can reduce manual work and error risk. If you use digital bookkeeping, your accountant can often access your data directly, speeding up the process and reducing the chance of missed claims. However, complex migrations or integrating multiple platforms can add to the initial bill.

From April 2026, Making Tax Digital for Income Tax Self Assessment (MTD ITSA) becomes mandatory for those with income over £50,000, and from April 2027 for those with £30,000+ income. Only accountants familiar with digital platforms can guarantee compliance and help you avoid penalties. At Tax Return Accountants, we support all major platforms and guide clients through MTD setup as standard—unlike many firms that charge extra for MTD onboarding.

Choosing an accountant based on their software expertise can save you hours of admin each year. For example, a Leicester ecommerce seller using Xero paid £60 more for an MTD-compliant accountant, but saved £250 per year in time and missed claims. For more on digital compliance, see our Making Tax Digital Service.
