Landlord accountants

Managing rental property involves more than collecting rent and paying the occasional repair bill. You need accurate records, correctly calculated profits, timely tax returns and a clear understanding of how each financial decision could affect your tax position.

Asmat & Co Accountants provides practical accounting and tax support for UK landlords. Whether you own 1 rental property, have inherited a property, operate a growing portfolio or hold properties through a limited company, we help you keep everything organised and compliant.

With 19 years of hands-on accounting experience, our team understands the issues landlords face in practice. We review your rental income, expenses, ownership structure and future plans before recommending the most appropriate way forward.

You receive clear explanations, proactive guidance and dependable support throughout the year, not just when your tax return is due.

Accounting support built around your property portfolio

No 2 landlords have exactly the same circumstances.

You may own a single buy-to-let property alongside a full-time job. You may manage several properties with different mortgages, letting agents and ownership arrangements. You may also be considering whether future purchases should be made personally or through a company.

Our service can be tailored to support:

• Individual buy-to-let landlords
• First-time and accidental landlords
• Joint property owners
• Married couples and civil partners with rental income
• Limited company property owners
• Landlords with several rental properties
• HMO landlords
• Commercial property owners
• Short-term and holiday accommodation providers
• Non-resident landlords with UK property
• Landlords preparing to buy, refinance or sell

We bring your property income and expenses together so that you can see what your portfolio is actually earning and what tax may be due.

What our landlord accounting service includes

Our support covers the day-to-day accounting, annual reporting and longer-term tax considerations connected with owning rental property.

Rental income and expense accounts

We prepare clear rental accounts showing the income received, allowable running costs and taxable profit or loss for the relevant period.

This may include reviewing:

• Rent received directly or through a letting agent
• Letting and property management fees
• Buildings and contents insurance
• Repairs and maintenance
• Ground rent and service charges
• Council Tax and utilities paid by you
• Accountancy and professional fees
• Cleaning, gardening and other property services
• Replacement of qualifying domestic items
• Mortgage interest and other eligible finance costs
• Advertising and administrative costs

We also help distinguish between a repair and a capital improvement. This is important because replacing a damaged item may be treated differently from upgrading or substantially improving the property.

Self Assessment tax returns for landlords

Rental income often needs to be reported through Self Assessment, even where tax has already been deducted from your employment or pension income.

Our tax return accountants can prepare and submit your return, calculate the tax due and make sure your property income is reported alongside your other income and gains.

We consider:

• UK rental income
• Foreign property income
• Employment or pension income
• Self-employment income
• Property business losses
• Payments on account
• Capital gains
• Relevant allowances and reliefs

You receive a clear calculation before anything is submitted to HMRC, giving you time to ask questions and prepare for the payment deadline.

Bookkeeping for rental properties

Good landlord accounting begins with reliable records.

Our bookkeeping services can organise rent statements, invoices, receipts, mortgage documents and letting agent reports throughout the year. This reduces the risk of missing expenses or trying to rebuild an entire year of transactions shortly before the filing deadline.

We can help you keep separate records for each property while also producing a combined view of your portfolio.

Accurate records are particularly helpful when:

• Different agents manage different properties
• You receive rent into several bank accounts
• A property has periods without a tenant
• Major repair work has been completed
• Costs relate partly to the property and partly to personal use
• You are preparing to refinance or sell

Making Tax Digital for Income Tax

Making Tax Digital for Income Tax began applying to the first group of eligible landlords from 6 April 2026.

You generally need to use it from 6 April 2026 if the qualifying income shown on your 2024/25 tax return from property and self-employment was more than £50,000. The threshold falls to more than £30,000 from 6 April 2027 and more than £20,000 from 6 April 2028.

Qualifying income is considered before expenses, so it should not be confused with your taxable rental profit.

Where the rules apply, you will need compatible software to:

• Create and maintain digital records
• Record property income and expenses
• send quarterly updates to HMRC
• Complete your end-of-year tax submission

Our certified QuickBooks accountants can help you set up a suitable digital record-keeping system, organise your property transactions and manage the required submissions.

We can also review whether you fall within the rules, rather than assuming that the value of your properties or your final profit determines your position.

Understanding allowable landlord expenses

You normally pay tax on your rental profit rather than the total rent received. Rental profit is broadly calculated after deducting costs that meet the conditions for tax relief.

Common allowable costs may include letting agent fees, insurance, routine maintenance, certain legal and professional fees, service charges and direct costs of managing the property.

However, not every payment made in connection with a property is immediately deductible.

For example:

• Repairing a broken boiler may be treated as a repair.
• Installing a substantially upgraded system may include capital expenditure.
• Replacing a damaged kitchen worktop may be a repair.
• Building an extension is normally a capital improvement.
• Mortgage capital repayments are not rental expenses.
• Residential mortgage interest for individual landlords is generally dealt with through a basic-rate tax reduction rather than deducted in full from rental income.

We review the purpose and supporting evidence for each significant cost instead of applying a broad category without considering the underlying transaction.

This helps you claim legitimate expenses without creating unnecessary risk through unsupported or incorrect claims.

Personally owned property or a limited company

Choosing whether to buy property personally or through a limited company is a major decision. A company is not automatically more tax-efficient, and transferring an existing property into a company can create additional tax, legal and financing consequences.

The right approach may depend on:

• Your existing income and Income Tax rate
• How much mortgage finance you require
• Whether profits will be withdrawn or reinvested
• Your expected holding period
• The number of properties you plan to acquire
• Other shareholders or family members involved
• Mortgage availability and interest rates
• Stamp taxes and acquisition costs
• Capital Gains Tax considerations
• Corporation Tax and dividend planning
• Succession and estate planning objectives
• Additional company administration

Our limited company accounting team can explain the accounting and tax responsibilities of operating a property company.

Before making a purchase or transferring a property, we can compare potential outcomes using your actual expected rent, costs, borrowing and personal circumstances. Legal, mortgage and property valuation advice should also be obtained where appropriate.

Jointly owned rental property

Joint ownership can affect how rental income is divided and reported.

Where property is owned by spouses or civil partners living together, rental income is normally taxed equally unless the beneficial ownership is unequal and the required conditions and HMRC declaration are satisfied.

Different considerations may apply where a property is owned with:

• A sibling
• An unmarried partner
• A business associate
• Several family members
• A formal property partnership

We review the legal and beneficial ownership, how the income is actually shared and whether the reporting treatment matches the underlying arrangement.

Changes should be considered before income is received or a transaction takes place. They should not be created retrospectively simply to produce a lower tax bill.

Mortgage interest and finance costs

Finance costs are one of the areas most likely to cause confusion for residential landlords.

Individual landlords are generally subject to restrictions on relief for residential mortgage interest and certain other finance costs. Instead of deducting the full cost when calculating rental profit, eligible finance costs are normally considered when calculating a basic-rate tax reduction.

This can produce a higher taxable income figure than some landlords expect, particularly where they have substantial borrowing or are already higher-rate taxpayers.

The treatment for property held by a limited company is different, but the wider company tax, profit extraction and administration position must also be considered.

We calculate the treatment based on your ownership structure and explain how borrowing costs affect both your tax calculation and your actual cash return.

Capital Gains Tax when selling a rental property

Selling or giving away a rental property can create a Capital Gains Tax liability.

For individuals, the calculation may need to consider:

• The original purchase price
• Certain purchase and sale costs
• Qualifying capital improvements
• Your ownership share
• Previous use of the property
• Available capital losses
• Private Residence Relief where relevant
• The annual exempt amount
• Your other taxable income and gains

Where Capital Gains Tax is due on the disposal of UK residential property, it will usually need to be reported and paid within 60 days of completion. This is separate from reporting the disposal through Self Assessment where required.

We recommend involving an accountant before completion whenever possible. This provides time to collect historic documents, estimate the gain and prepare for the reporting and payment deadline.

Short-term and holiday accommodation

The former furnished holiday lettings tax regime was abolished from April 2025. Income from short-term and holiday accommodation is now generally treated under the usual property income rules rather than receiving the previous furnished holiday letting tax advantages.

However, your exact obligations can still depend on the services provided, the ownership structure and whether other taxes, including VAT, may be relevant.

We can review your income sources, platform statements, fees, cleaning costs and property expenditure so that the correct treatment is applied.

Support for non-resident landlords

Living outside the UK does not remove your responsibility to report income or gains arising from UK property.

The Non-resident Landlord Scheme may affect whether a letting agent or tenant must deduct tax from rent before paying it to you. You may be able to apply to HMRC to receive rent without deduction, but you will still need to meet your UK reporting and payment responsibilities.

We can help with:

• Registration and HMRC correspondence
• Rental income accounts
• Self Assessment tax returns
• Non-resident landlord applications
• UK property disposal reporting
• Communication with letting agents
• Reviewing tax already deducted

Your residence status and any overseas reporting requirements should also be considered alongside your UK position.

Tax planning throughout the property lifecycle

Useful tax planning should take place before a decision becomes irreversible.

We can support you when you are:

• Purchasing your first rental property
• Adding another property to your portfolio
• Changing ownership arrangements
• Refinancing existing borrowing
• Moving a property into or out of a company
• Starting short-term or holiday letting
• Bringing a spouse or business partner into the structure
• Planning a property sale
• Passing property to the next generation
• Leaving or returning to the UK

We explain the likely tax and accounting consequences so that you can make an informed commercial decision. The aim is not simply to reduce this year’s tax bill. It is to create an arrangement that remains practical as your portfolio and personal circumstances change.

Clear reports for better property decisions

A tax return tells you what has already happened. Good management information helps you decide what to do next.

Where appropriate, we can provide periodic reports showing:

• Rental income by property
• Direct property expenses
• Mortgage and finance costs
• Net cash generated
• Tax provisions
• Outstanding amounts
• Portfolio-wide performance
• Comparisons between properties

This can help you identify properties with rising costs, weak cashflow or lower returns before making decisions about rent reviews, refinancing, repairs or disposals.

Frequently asked questions

What do landlord accountants do?

Landlord accountants organise rental income and expenses, prepare property accounts, complete tax returns and advise on issues such as allowable costs, mortgage interest, joint ownership, limited companies, Making Tax Digital and property disposals.

They can also help you maintain suitable evidence for your claims, prepare for tax payments and understand the actual cash return produced by each property.

Do I need an accountant for rental income?

There is no general rule requiring every landlord to appoint an accountant. However, professional support can be valuable if you have significant expenses, mortgage finance, several income sources, jointly owned property, a limited company, overseas circumstances or an upcoming property sale.

An accountant can also help where you are unsure whether a cost is a repair, an improvement or a private expense.

What expenses can landlords claim against rental income?

Potentially allowable expenses include letting agent fees, accountancy fees, insurance, routine repairs, maintenance, service charges, ground rent and certain direct costs of managing the property.

The expense must meet the relevant tax conditions. Capital improvements, mortgage capital repayments and personal costs are not normally deducted as day-to-day rental expenses. Mortgage interest for individual residential landlords is subject to separate finance-cost rules.
