Tax Return Costs for Property Owners | Guide for UK Landlords

Being a landlord in the UK is profitable as it provides a steady stream of income alongside the potential for long-term property value growth. However, you must know that it comes with tax responsibilities.

Whether you manage a larger property portfolio or rent out a single property, it is important to understand your tax obligations to avoid unexpected bills. This will make sure you claim the deductions you are entitled to. But what are the tax return costs for property owners?

This guide focuses primarily on UK individuals who own and let residential or other rental property. It also explains property tax return costs, including rental property accountant fees, and the deductions that may be available to UK property owners.

Note: Different rules can apply to companies, partnerships and certain overseas property arrangements.

How Much Does a Landlord Tax Return Cost?

There is no standard price for a property tax return. The cost of a landlord tax return depends on how much work your accountant needs to complete. A simple tax return with one rental property and well-organised records will generally require less work than a return involving numerous expenses and additional tax considerations.

What Are Tax Return Costs for Property Owners?

In the UK, there is no single fixed tax return cost for property owners. The cost will generally depend on the amount of work required and the complexity of your circumstances.

If you have straightforward rental income and well-organised records, preparing a Self Assessment tax return may be relatively simple. However, if you have capital gains, multiple rental properties, jointly owned properties, overseas property or other sources of income, then costs can increase.

When considering the cost of a property tax return, you should look beyond the headline fee. An expert accountant may also help identify allowable expenses, apply the relevant property-income rules and ensure that the return is completed and submitted correctly.

How Much Are Landlord Accountant Fees in the UK?

Landlord accountant fees in the UK typically range from £150 to £500 per year for an individual property owner filing a standard Self Assessment tax return. This is the basic rate that covers a single rental property with simple income and expenses.

For larger portfolios, limited company structures, or complex tax planning, it scales up to £500 to £3,000+ per year. For individuals who complete a Self Assessment tax return, rental income and relevant property expenses are generally reported on the SA105 UK property pages. Keep in mind that if you own multiple properties, the price may increase.

What Determines Tax Return Costs for Property Owners?

As mentioned, tax return costs can vary depending on the amount of work required and the complexity of the taxpayer’s circumstances. It also depends on:

Rental Income

Different types of property income or more transactions may require additional time to review and reconcile. An accountant may charge more if records of rental income and other relevant property receipts are inaccurate.

Property Expenses

Allowable expenses can reduce taxable property profits. Generally, revenue expenses incurred wholly and exclusively for the property business may be deductible, subject to the relevant tax rules. Capital expenditure is treated differently and may qualify for relief under separate rules.

You must keep accurate records of expenses and supporting documents, as it can make the tax return easier to prepare. Also, this may reduce the time an accountant needs to spend checking the information.

Number of Rental Properties

Another factor that determines tax return costs for property owners is the number of properties you own. This can affect the amount of work involved. Having multiple rental properties means reviewing rental income, expenses, and supporting records for each property.

Moreover, the overall tax treatment can depend on how the properties are held and the applicable property income rules.

Quality and Organisation of Records

The organisation and quality of your financial records can affect the amount of work involved. If you have clear, complete and well-organised records, it can make the preparation process simpler. However, if there are incomplete, disorganised or missing records, it may require additional review, clarification or bookkeeping work. This can increase the overall fee.

Property Sales

Your property sales also determine the tax return costs for property owners. Selling a property involves additional calculations. Depending on your circumstances and the property, the sale may give rise to Capital Gains Tax (CGT) and may require additional tax work.

Ownership Structure

Your tax position can depend on how you own the property. Different considerations may apply when property is owned personally, through a partnership or through a company.

Joint ownership can also affect the amount of work required. The tax treatment depends on the ownership arrangement and who is entitled to the rental profits. Joint ownership does not automatically mean that a partnership exists.

Complexity of Your Tax Affairs

The complexity of your overall tax affairs, the level of bookkeeping required, and whether additional tax calculations or advice are needed can affect the tax return costs for property owners.

Since these factors vary between landlords, there is no single standard price for a rental property tax return. Generally, the final fee depends on the complexity of the property income and the amount of work required to prepare the return.

Accountant and Location

Mind you that accountant fees can vary between firms and locations. Accounting firms in London and other major cities may have different pricing structures from regional firms. The reason is the differences in operating costs, market conditions, and the services offered.

However, there is no standard percentage difference that applies to all accountants across locations.

What is Included in a Landlord Tax Return?

Tax return costs for property owners generally involve reporting property income and allowable expenses to HM Revenue and Customs (HMRC).

Depending on your circumstances, an accountant may help to:

• Calculate rental income
• Review property-related expenses
• Prepare the property pages of your Self Assessment
• Identify available tax relief
• Calculate your taxable property profit
• Submit the return to HMRC
• Explain the tax liability and payment deadlines
• Advise on property tax matters where this forms part of the agreed service

This is why the rental property tax return cost covers more than just entering numbers into an online form.

What are Accountant Fees for Limited Company Property?

If you own a rental property through a limited company, it can involve more accounting and reporting work than owning property personally.

Usually, a limited company needs to prepare annual accounts for Companies House and submit a Company Tax Return to HMRC. This can increase tax return costs for property owners.

Accountant fees vary based on the company’s property portfolio, transactions, and the services included. Additional services or more complex portfolios can result in higher accounting costs.

DIY vs Accountant: Which Is Cheaper?

DIY tax returns can be cheaper because you do not pay any accountant fees. However, hiring an accountant can save time and help reduce the risk of errors, particularly when you have multiple properties and complex expenses.

If you have a straightforward rental property tax return, doing your own tax return may be more cost-effective. However, if you have more complex situations, paying an accountant may provide better value.

Does Making Tax Digital Affect Tax Return Costs for Property Owners?

Yes, Making Tax Digital (MTD) may increase the cost of ongoing accounting and record-keeping for affected landlords. You may need compatible software, digital record-keeping, and quarterly reporting. This can increase the tax return costs.

However, software costs vary, and a few free and low-cost options are available. So, when considering a property tax accountant, you should look beyond the annual accountant’s fee and consider any ongoing costs associated with digital record-keeping and MTD compliance.

Note: From 6 April 2026, MTD applies to landlords with qualifying income of more than £50,000. This threshold will reduce to more than £30,000 in 2027 and more than £20,000 in 2028.

How to Reduce Your Rental Property Tax Return Cost?

Tax return costs for property owners can be reduced by making your records clear and organised.

Keep Good Records

Keep accurate records of rental income, repairs, insurance, letting-agent fees and finance costs. Residential landlords who own property personally are subject to specific rules for mortgage interest and other finance costs. Therefore, they should be recorded separately and treated correctly for tax purposes.

Keep Property Transactions Organised

Keep your transactions organised. To do so, use a separate bank account for property transactions. This can make it easier to track rental income and expenses.

Prepare Documents Beforehand

Sort your receipts and records and give them to your accountant. This can reduce the time needed to review and process your information.

Check Accountant’s Services Include

Before hiring an accountant, you should check whether their fee covers basic bookkeeping, tax calculations, property income reporting, MTD submissions (where applicable), and any additional services you may require.

Final Thoughts

Tax return costs for property owners vary depending on the income, expenses, number of properties, ownership structure, and the level of professional support required.

For simple tax affairs, filing your own Self Assessment may cost less, but for complex property portfolios, you may have to hire an accountant. This may increase the costs.  However, you can reduce the cost by keeping organised records and choosing the right level of support.
