Filing a tax return can feel confusing, especially if you are doing it for the first time. Many people are unsure whether they need professional help and, if they do, how much it is likely to cost. The answer depends on several factors, including the complexity of your finances, the type of income you receive, and the level of support you need.
In the UK, accountant fees for tax returns can range from relatively modest amounts for straightforward cases to significantly higher fees for more complicated tax affairs. Understanding these costs can help you budget properly and choose the right level of support.

Tax Return Accountant Cost Per Hour vs Fixed Fees
When obtaining quotes, you may notice that some accountants charge fixed fees while others bill by the hour.
Understanding the difference can help you choose the arrangement that best suits your needs.
Tax return accountant cost per hour in the UK
Hourly rates vary widely.
Factors influencing hourly charges include:
- Professional qualifications
- Years of experience
- Geographic location
- Specialist expertise
Typical hourly rates range from £75 to £250 per hour.
Senior advisers handling complex matters may charge even more.
Hourly billing can work well when the scope of work is uncertain, but it can make budgeting more difficult.
Fixed-fee tax return services explained
Many clients prefer fixed fees because they provide certainty.
With this approach, the accountant agrees on a price before beginning the work.
Benefits of fixed fees include:
- Greater transparency
- Easier budgeting
- Clear expectations
- Reduced concern about additional charges
Fixed fees are particularly common for Self Assessment tax returns.
Fixed fee vs hourly rate: which offers better value?
Neither approach is automatically better.
Fixed fees may represent better value when:
- Your affairs are relatively straightforward
- You want cost certainty
- The scope of work is clearly defined
Hourly billing may be more suitable when:
- Complex issues arise unexpectedly
- Specialist advice is required
- The amount of work cannot easily be predicted
The key is understanding exactly what is included in the quoted fee.
One-off payments vs ongoing accounting support
Some taxpayers only require assistance once a year. Others benefit from regular contact with their accountant.
One-off services are often suitable for:
- Employees with simple returns
- Individuals with occasional filing obligations
Ongoing support may suit:
- Growing businesses
- Self-employed professionals
- Landlords with expanding portfolios
- Directors requiring year-round advice
The best option depends on your circumstances and the level of support you value.
Tax Return Accountant Cost Per Month: Are Monthly Packages Worth It?
Many accounting firms now offer monthly service packages.
These arrangements spread costs across the year and often include broader support beyond tax return preparation.
One-off tax return filing vs monthly accounting packages
A one-off filing service focuses solely on preparing and submitting the annual tax return. Monthly packages typically provide ongoing assistance.
The differences can be significant.
Service Feature | One-Off Filing | Monthly Package |
Annual tax return | ✔ | ✔ |
Regular bookkeeping support | ✘ | ✔ |
Tax planning advice | Limited | Often included |
Access to accountant throughout the year | Limited | ✔ |
Monthly cost spread | ✘ | ✔ |
Choosing between these options depends largely on your needs.
What is included in a monthly accounting package?
Although packages vary, common features include:
- Bookkeeping support
- Tax return preparation
- Business advice
- Access to accounting software
- VAT guidance where applicable
- Ongoing tax planning discussions
- Regular contact with an adviser
For business owners, these services can provide peace of mind throughout the year.
The value of ongoing tax and accounting support
Waiting until January to think about tax can create unnecessary stress.
Regular support may help taxpayers:
- Stay organised
- Improve record-keeping habits
- Prepare for future liabilities
- Identify opportunities for tax efficiency
- Avoid last-minute filing pressures
For some individuals, the additional cost of ongoing support can be justified by the convenience and proactive guidance received.
In the next part of this guide, we will explain what a tax return accountant actually does, the factors that influence accountant fees, and the typical costs faced by different categories of UK taxpayers.
What Is a Tax Return Accountant?
A tax return accountant is a professional who helps individuals and businesses prepare, review, and submit their tax returns accurately. Their role goes beyond simply entering figures into a form. They can provide guidance on tax rules, identify available reliefs, and help clients avoid costly mistakes.
For many people, working with an accountant reduces stress and saves valuable time, particularly when tax affairs become more complicated.
What does a tax return accountant do?
The exact services offered can vary, but most tax return accountants provide support with:
- Gathering and reviewing financial information
- Preparing Self Assessment tax returns
- Calculating tax liabilities
- Identifying allowable expenses and reliefs
- Submitting returns to HMRC
- Answering tax-related questions
- Communicating with HMRC where authorised
- Providing advice to improve future tax efficiency
Many accountants also help clients understand upcoming deadlines and changes to tax regulations.
Who typically needs help with a tax return?
Some people are comfortable completing their own returns, especially if their affairs are straightforward. However, professional support is often valuable for those with more complex circumstances.
People who commonly seek assistance include:
- Sole traders and freelancers
- Landlords receiving rental income
- Limited company directors
- Individuals with foreign income
- People with investment income
- High earners with additional tax considerations
- Taxpayers who have received a notice to file from HMRC
Even individuals with relatively simple tax affairs may choose to use an accountant for reassurance and convenience.
What Factors Influence Tax Return Accountant Fees in the UK?
Not all tax returns require the same amount of work. This is one of the main reasons why accountant fees can vary significantly from one client to another.
Understanding these factors can help explain the differences you may see when requesting quotes.
The complexity of your financial affairs
Complexity is often the biggest driver of cost. Factors that can increase complexity include:
- Multiple sources of income
- Self-employment activities
- Rental properties
- Capital gains transactions
- Overseas income
- Investment portfolios
The more information that needs reviewing, the more time an accountant will need to spend on the engagement.
The quality of your record-keeping
Good record-keeping can help keep fees under control. Clients who provide:
- organised spreadsheets,
- clearly labelled documents,
- complete expense records, and
- accurate income information,
often benefit from lower fees because less time is spent sorting and correcting information.
In contrast, incomplete or disorganised records can lead to additional charges.
Chartered status and qualifications
Accountants with recognised professional qualifications may charge higher fees.
This can reflect:
- advanced technical knowledge,
- ongoing professional development requirements,
- adherence to ethical standards, and
- broader experience dealing with complex situations.
While qualifications are important, they should be considered alongside experience and the quality of service provided.
Your location within the UK
Location can also influence pricing.
For example, firms operating in major cities may have higher overhead costs than those based elsewhere in the country.
However, the rise of online accounting services means that many taxpayers now have access to professional support regardless of where they live.
It is often worth comparing several providers rather than assuming that local options offer the best value.
Additional services included in the fee
A basic filing service may be relatively inexpensive. However, fees can increase if the service also includes:
- tax planning advice,
- bookkeeping assistance,
- expense reviews,
- capital gains calculations,
- HMRC correspondence support, or
- representation during enquiries.
When comparing quotes, always check what is included.
Regular clients vs one-off engagements
Existing clients who receive ongoing services may benefit from lower tax return fees because their accountant is already familiar with their circumstances.
By contrast, one-off engagements often involve additional time spent gathering information and understanding the client’s financial position.
As a result, annual clients sometimes receive more favourable pricing structures.
Why do accountant fees vary so much?
There is no standard pricing model across the accounting profession.
Fees can differ because of:
- varying levels of experience,
- differences in service scope,
- specialist expertise,
- regional pricing trends, and
- individual business models.
Rather than focusing solely on cost, it is important to consider the overall value being offered.
Typical Accountant Costs for Different Types of Taxpayers
Different groups of taxpayers often have different requirements. As a result, the average fee for tax return services can vary considerably.
Tax return accountant cost for sole traders and freelancers
Sole traders often need support with both income reporting and expense claims.
Typical services include:
- reviewing business income,
- checking allowable expenses,
- preparing the Self Assessment return, and
- calculating the tax due.
Average fees generally range from £250 to £500.
Costs may increase if bookkeeping records require substantial attention.
Tax return accountant cost for landlords
Landlords must report rental income and may need guidance on allowable expenses and changes affecting property taxation.
Factors influencing cost include:
- the number of properties owned,
- whether properties are jointly owned,
- mortgage interest considerations, and
- the quality of record-keeping.
Typical fees range from £250 to £700, depending on complexity.
Tax return accountant cost for limited company directors
Directors often have more complicated tax affairs.
Income may come from a combination of:
- salary,
- dividends,
- benefits in kind, and
- other investments.
Average tax return fees for directors commonly fall between £300 and £750.
Where additional tax planning advice is required, fees may exceed this range.
Tax return accountant cost for individuals with multiple income sources
Taxpayers with several income streams often require more detailed analysis.
Examples include individuals receiving income from:
- employment,
- self-employment,
- rental properties,
- dividends, and
- investments.
Because additional calculations and checks are needed, fees frequently start from £400 to £800 or more.
Professional support can be particularly valuable in ensuring that all income is reported correctly.
What Services Are Included in Tax Return Accountant Fees?
One of the most important questions to ask before appointing an accountant is what the quoted fee actually covers.
While every firm is different, several services are commonly included.
Preparing and submitting your Self Assessment tax return
This is the core service provided by most tax return accountants.
It usually involves:
- Gathering financial information.
- Reviewing the figures supplied.
- Completing the relevant tax return sections.
- Submitting the return to HMRC.
- Providing confirmation of filing.
The exact scope may vary depending on complexity.
Reviewing allowable expenses and tax reliefs
An experienced accountant will often review whether you have claimed all relevant expenses and reliefs.
Potential areas considered may include:
- business expenses,
- professional subscriptions,
- pension contributions,
- charitable donations, and
- property-related expenses.
Claiming legitimate deductions correctly can reduce the amount of tax payable.
Calculating your tax liability
Many taxpayers want clarity regarding how much tax they owe.
Accountants generally calculate:
- income tax liabilities,
- National Insurance contributions where applicable,
- payments on account, and
- relevant balancing payments.
Understanding these figures in advance can support better financial planning.
Providing tax planning advice
Some accountants also provide guidance aimed at improving tax efficiency in future years.
Examples of tax planning discussions may include:
- pension contribution strategies,
- timing of income and expenditure,
- dividend planning for directors, and
- improving record-keeping processes.
The level of advice included will depend on the agreed service.
Communicating with HMRC on your behalf
Where authorised, an accountant can correspond directly with HMRC.
This may involve:
- responding to routine queries,
- discussing return-related matters, or
- clarifying information requests.
Many clients value having a professional point of contact for these interactions.
Support with HMRC enquiries and correspondence
In some cases, HMRC may request additional information after a return has been submitted.
Some firms include limited enquiry support within their standard fee, while others charge separately.
It is important to ask:
- whether enquiry support is included,
- what level of assistance is provided, and
- whether additional charges may apply.
Understanding this in advance can help avoid unexpected costs later.
How to Choose the Right Self Assessment Tax Return Accountant
Choosing an accountant is an important decision. While price matters, it should not be the only factor considered.
The right adviser should provide confidence, clear communication, and support that matches your needs.
Should you choose a local accountant or an online accountant?
Both options can work well.
A local accountant may offer:
- face-to-face meetings,
- familiarity with local business communities, and
- a more traditional service model.
Online accountants may provide:
- flexible communication methods,
- secure digital document sharing,
- competitive pricing, and
- convenient access from anywhere in the UK.
The best choice often depends on personal preference.
What to look for when comparing accountants
Before making a decision, consider factors such as:
- relevant experience,
- professional qualifications,
- transparency of pricing,
- communication style,
- turnaround times, and
- availability throughout the year.
Taking the time to compare providers can help ensure a better long-term relationship.
How to find a reliable tax return accountant in the UK
Practical ways to identify suitable accountants include:
- asking for recommendations,
- reading independent reviews,
- checking professional memberships,
- arranging introductory consultations, and
- requesting written fee quotations.
A reliable accountant should be willing to explain their services clearly and answer your questions.
Why expertise matters more than price alone
Choosing the cheapest option is not always the best approach.
An experienced accountant may help you:
- avoid costly mistakes,
- identify available tax reliefs,
- improve compliance, and
- reduce stress during the filing process.
Professional expertise can represent good value, particularly when dealing with more complicated tax affairs.
In the next part of this guide, we will look at whether you actually need an accountant for your tax return, practical ways to reduce accountant costs, the impact of Making Tax Digital, frequently asked questions, and how to choose the best tax return accountant for your needs.
Do You Need an Accountant for Your Tax Return?
Many people wonder whether hiring an accountant is necessary. The answer depends on your individual circumstances. Some taxpayers are comfortable completing their own Self Assessment tax return, while others prefer the reassurance of professional support.
The decision often comes down to the complexity of your finances, the amount of time you have available, and your confidence in understanding tax rules.
Is it worth paying an accountant for a simple tax return?
For individuals with straightforward tax affairs, it may be possible to complete a Self Assessment tax return independently.
However, many people still choose to work with an accountant because it can:
- save time,
- reduce stress,
- provide reassurance that the return has been completed correctly, and
- minimise the risk of avoidable errors.
The cost of professional support may be worthwhile if it allows you to focus on other priorities.
When should you consider hiring an accountant?
Professional advice may be particularly useful if you:
- have become self-employed,
- receive rental income,
- have multiple income sources,
- are a company director,
- have sold assets that could trigger Capital Gains Tax,
- have overseas income, or
- have received correspondence from HMRC that you do not understand.
The more complex your situation becomes, the greater the potential benefit of expert guidance.
The benefits of professional tax support
Working with an accountant offers several advantages.
These may include:
- improved accuracy,
- greater confidence in compliance,
- assistance with understanding tax obligations,
- reduced administrative burden, and
- access to professional advice when circumstances change.
For many taxpayers, peace of mind is one of the biggest benefits.
Situations where professional advice can save you money
An accountant cannot make tax liabilities disappear, but they can help ensure that legitimate reliefs and deductions are not overlooked.
Professional advice may help in situations involving:
- business expenses,
- pension contributions,
- property income,
- dividend planning,
- capital gains considerations, and
- changes to business structures.
Making informed decisions throughout the year can sometimes lead to more efficient tax outcomes.
Practical Tips to Reduce Your Tax Return Accountant Cost
While professional support represents an investment, there are practical steps you can take to keep fees under control.
Being organised and prepared often results in a smoother process for both you and your accountant.
Keep your financial records organised
Well-maintained records reduce the amount of time an accountant needs to spend sorting information.
Useful habits include:
- keeping receipts in one place,
- updating income records regularly,
- separating personal and business transactions, and
- maintaining clear summaries of expenses.
Good organisation can contribute to lower fees.
Prepare information well in advance
Leaving everything until January often creates unnecessary pressure. Providing information early gives your accountant sufficient time to review your records properly.
It may also reduce the likelihood of additional charges associated with urgent work.
Understand what services you actually need
Not everyone requires a comprehensive package.
Before requesting quotes, consider whether you need:
- basic tax return preparation,
- tax planning advice,
- bookkeeping support,
- HMRC correspondence assistance, or
- ongoing accounting services.
Choosing a service that aligns with your needs can prevent overspending.
Become an easy client to work with
Accountants value clients who respond promptly and provide complete information.
Simple steps include:
- answering queries quickly,
- submitting requested documents together,
- checking figures before forwarding them, and
- notifying your accountant about significant financial changes.
Efficiency often benefits both parties.
Compare fees and service levels before deciding
Obtaining several quotations allows you to compare value rather than focusing exclusively on price.
Questions to consider include:
- What services are included?
- Are there any additional charges?
- Is support available throughout the year?
- How will communication take place?
A slightly higher fee may represent better value if it includes broader support.
Self Assessment Tax Returns and Making Tax Digital
The UK tax system continues to evolve. One important development is the government’s Making Tax Digital initiative.
Understanding these changes can help taxpayers prepare for future obligations.
What is Making Tax Digital?
Making Tax Digital, often referred to as MTD, is a government programme designed to modernise the tax system.
The initiative encourages taxpayers to maintain digital records and submit information electronically.
Further details can be found on the official HMRC guidance:
https://www.gov.uk/government/publications/making-tax-digital
The aim is to improve accuracy and streamline tax administration.
How Making Tax Digital could affect future tax obligations
As the initiative expands, some taxpayers may need to:
- keep digital financial records,
- use compatible software,
- submit information more frequently, and
- adapt existing bookkeeping practices.
Requirements will depend on individual circumstances and the relevant implementation timelines.
Remaining informed about upcoming changes can help reduce disruption.
Will Making Tax Digital change accountant fees?
The impact on fees is likely to vary.
For some taxpayers, improved digital record-keeping could reduce administrative work.
For others, there may be additional costs associated with:
- adopting new software,
- receiving training and support, or
- obtaining ongoing bookkeeping assistance.
Over time, efficient digital systems may contribute to smoother processes and improved accuracy.
Frequently Asked Questions
What expenses can I claim on my tax return?

Self-employed individuals may be able to claim allowable business expenses that are incurred wholly and exclusively for business purposes.
Examples can include:
- office costs,
- travel expenses,
- professional fees,
- insurance costs, and
- certain equipment purchases.
HMRC provides detailed guidance on allowable expenses:
https://www.gov.uk/expenses-if-youre-self-employed

You may need to file a Self Assessment tax return if you:
- are self-employed,

- earn rental income,
- have significant investment income,
- are required to report capital gains, or
- receive a notice from HMRC instructing you to file.
Requirements can change depending on personal circumstances.
What is the minimum income threshold for filing a tax return?
There is no single threshold that applies to everyone.
Whether you need to file depends on factors such as:

- the amount received,
- whether tax has already been deducted, and
- specific reporting requirements issued by HMRC.
If you are uncertain, it is sensible to seek clarification rather than assume that filing is unnecessary.
How do I file a tax return in the UK?
The process generally involves:

Waiting until the final weeks before the deadline can limit available options.
Does the accountant’s fee include dealing with HMRC?
This varies between firms.
Some accountants include routine HMRC correspondence within their standard fee, while others charge separately.
Before proceeding, ask whether the quoted price covers:

- responding to routine queries,
- support during enquiries, and

Understanding the scope of the service helps avoid misunderstandings later.
