Choosing the right landlord accountant is about more than filing a return. Use these 10 questions to find an accountant who understands UK property income, MTD, digital records and landlord-specific responsibilities.
Choosing the right accountant for your rental property business is not simply about finding the lowest fee. A good landlord accountant should understand property income, allowable expenses, mortgage finance costs, digital record-keeping, Making Tax Digital and the deadlines that can arise when a property is sold.
They should also explain their fees clearly, respond when you need help and understand whether you own property personally, jointly, through a limited company or from outside the UK.
This guide explains the questions every UK landlord should ask before appointing an accountant.
What should a good landlord accountant provide?
The right accountant should be able to help you:
Record rental income and property expenses correctly
Prepare your Self Assessment return and property pages
Review allowable expenses and finance costs
Keep records organised for each property
Understand your Making Tax Digital responsibilities
Prepare quarterly updates where required
Deal with HMRC on your behalf when authorised
Plan ahead when buying, selling or restructuring property
Understand the accounting requirements of a property limited company or SPV
Keep you informed about deadlines and missing information
The exact service will depend on your circumstances, so the scope and fee should always be confirmed in writing.
Why landlord experience matters
Rental property accounting has its own rules, records and deadlines.
A general accountant may be able to complete a landlord’s Self Assessment return. However, an accountant who regularly works with landlords is more likely to understand issues such as:
Property income versus rental profit
Jointly owned properties
Allowable repairs versus capital improvements
Residential property finance cost restrictions
The £1,000 property allowance
Making Tax Digital for Income Tax
Capital Gains Tax when a property is sold
Furnished holiday letting changes
Property held personally versus through a limited company
Non-Resident Landlord Scheme requirements
This does not mean every landlord needs complicated advice. It means the accountant should know which questions to ask before completing the work.
10 questions to ask before choosing a landlord accountant
1. How much experience do you have with UK landlords?
Ask whether the accountant regularly supports landlords, property investors and property limited companies.
A useful answer should explain the types of landlord clients they handle, such as:
Landlords with one or two properties
Portfolio landlords
Joint property owners
Limited-company or SPV landlords
Non-resident landlords
Landlords affected by Making Tax Digital
Be cautious if “property accounting” appears in the accountant’s marketing but they cannot clearly explain what landlord-specific work they provide.
2. Do you support personally owned and limited-company properties?
Owning a rental property personally is different from owning it through a limited company.
An individual landlord will normally report rental income through Self Assessment. A property company may need annual accounts, a Company Tax Return and Companies House filings.
An accountant should understand both arrangements. They should not automatically recommend moving properties into a company without reviewing your wider circumstances.
Ownership decisions can affect borrowing, administration, profit withdrawals and future property sales. The cheapest-looking structure is not automatically the most suitable one.
3. What exactly is included in your fee?
“Landlord accounting included” can mean very different things.
Ask whether the quoted fee includes:
Self Assessment and the property pages
Rental income and expense review
Bookkeeping
Property-by-property records
Annual property accounts
HMRC submissions
Making Tax Digital quarterly updates
Year-end reporting
Accounting software
Support with HMRC queries
Advice when buying or selling property
Limited-company accounts and Companies House filings
Additional properties
Also ask which services are charged separately. A low headline price can become expensive when ordinary landlord work is treated as an add-on.
4. Who will handle my account?
Find out whether you will have a named contact or whether every question will enter a general support queue.
Ask:
Who will manage my account?
How can I contact them?
What is the normal response time?
Will the same person review my records each year?
Who covers the account when that person is unavailable?
A named contact who understands your portfolio can reduce repeated explanations and help identify missing information earlier.
5. Are you ready for Making Tax Digital?
Making Tax Digital for Income Tax began on 6 April 2026 for eligible sole traders and landlords.
Under the current timetable:
Qualifying income over £50,000 for 2024–25 means MTD should have started from 6 April 2026
Qualifying income over £30,000 for 2025–26 means MTD starts from 6 April 2027
Qualifying income over £20,000 for 2026–27 means MTD starts from 6 April 2028
Qualifying income is the total gross income from property and self-employment before expenses. Income from both sources may need to be combined.
For example, a landlord receiving £35,000 in gross rent and £20,000 from self-employment would have £55,000 of qualifying income.
HMRC confirms that landlords must check their own position, even if they have not received a letter. You can read the current Making Tax Digital eligibility guidance and the rules for working out qualifying income.
Ask the accountant:
Will you check whether MTD applies to me?
Will you complete my quarterly updates?
Is compatible software included?
Who will record transactions during the year?
What information will I need to provide?
Will you also complete the final year-end submission?
Quarterly updates are not a replacement for accurate year-end reporting. The accountant should explain the complete process, not just sell access to software.
6. How will my digital records be managed?
A landlord accountant should provide a simple method for recording rental income and expenses.
Ask whether you will use:
Accounting software
A mobile receipt-capture application
Bank feeds
A spreadsheet connected to compatible software
A secure document portal
The system should allow records to be organised by property, particularly if you own more than one.
You should also know who is responsible for categorising transactions, checking missing documents and correcting errors. Software helps with record-keeping, but it does not replace proper review.
Never give an accountant your personal Government Gateway password. They should use the correct HMRC agent-authorisation process.
7. How do you review expenses and mortgage finance costs?
Not every payment connected with a property is automatically deductible.
HMRC generally allows revenue expenses that are incurred wholly and exclusively for the rental business. Common examples can include letting-agent fees, landlord insurance, repairs, accountancy costs and certain service charges. The correct treatment depends on the nature of each expense.
Capital improvements are normally treated differently from routine repairs.
For individual residential landlords, mortgage interest and certain other finance costs are generally subject to the basic-rate finance cost reduction rather than being deducted in full from rental income. Different rules may apply to property companies and non-residential property.
A good accountant should review the records instead of blindly copying the categories selected in the bookkeeping software. HMRC provides further guidance on working out rental income and allowable expenses and the residential landlord finance cost restriction.
8. Can you help when I sell a property?
A property sale can create an earlier reporting deadline than many landlords expect.
Where Capital Gains Tax is due on the sale of UK residential property, it will normally need to be reported and paid within 60 days of completion. The disposal may also need to be included in the relevant Self Assessment return.
Ask whether the accountant can:
Review the original purchase information
Check buying and selling costs
Review qualifying improvement expenditure
Consider available losses and reliefs
Estimate the potential gain before completion
Prepare the required property disposal return
Include the disposal in the annual return where necessary
Do not wait until the next Self Assessment deadline to mention a completed sale. Read HMRC’s current 60-day property reporting guidance.
9. What professional and security checks can I make?
Before sharing financial records, identification documents or property information, ask:
Who supervises the firm for anti-money laundering compliance?
Does the firm follow HMRC’s standard for agents?
Is any professional-body membership clearly stated and verifiable?
Does the firm hold professional indemnity insurance?
How are documents and personal data protected?
Will I receive written engagement terms?
How will the firm obtain authority to deal with HMRC?
Professional tax agents must meet relevant registration, supervision and conduct requirements. HMRC explains the key requirements in its guidance for professional tax agents.
A professional logo or impressive website is not evidence by itself. Check the underlying details.
10. What happens if I switch accountants?
Changing accountants should not mean starting your financial records again.
With your permission, the new accountant will normally request professional clearance and relevant information from the previous accountant.
Ask what the new accountant will need, such as:
Previous returns and calculations
HMRC correspondence
Property income and expense records
Mortgage statements
Capital allowance schedules
Company accounts and returns
Details of losses carried forward
Accounting software access
Existing HMRC authorisations
The new accountant should also check upcoming deadlines and identify any missing submissions before accepting responsibility for the work.
Warning signs to avoid
Be cautious if an accountant:
Promises guaranteed savings before reviewing your circumstances
Recommends a limited company to every landlord
Cannot explain how MTD will be handled
Provides a price without confirming what is included
Has no written engagement terms
Refuses to explain who supervises the firm
Requests your Government Gateway password
Cannot provide a clear response time
Uses unfamiliar junior staff without explaining who reviews the work
Only contacts you shortly before the annual filing deadline
Makes decisions without asking about ownership, mortgages or future plans
The cheapest accountant can become the most expensive when important work is excluded or problems are discovered late.
When should a landlord appoint an accountant?
Professional support becomes particularly valuable when:
You have more than one property
A property is jointly owned
Your records are incomplete or behind
You also receive self-employment income
Your qualifying income brings you into Making Tax Digital
You are buying or selling a property
You are considering a property limited company
You own property through an SPV
You live outside the UK
HMRC has contacted you
You have missed a filing deadline
You want clearer property-by-property records
It is usually easier to appoint an accountant before a major transaction or deadline. Advice received after completion may arrive too late to change the available options.

Frequently asked questions
Does every UK landlord need an accountant?
No. A landlord can maintain their own records and complete their own submissions. However, the landlord remains responsible for accurate information and meeting HMRC deadlines.
An accountant can be particularly helpful when a landlord has multiple properties, a company, incomplete records, a property disposal or Making Tax Digital responsibilities.
Can a general accountant prepare landlord accounts?
Yes, but you should check their level of property experience. Rental income, finance costs, jointly owned properties, property disposals and MTD can require knowledge beyond completing a basic Self Assessment return.
Does Making Tax Digital apply to rental income?
Yes, it can apply to individual landlords when their combined gross income from property and self-employment is above the relevant threshold.
The rules currently apply in phases, beginning with qualifying income over £50,000 from April 2026.
What records should I keep?
Useful records normally include:
Tenancy agreements
Rental statements
Bank statements
Letting-agent statements
Mortgage interest statements
Insurance documents
Repair and maintenance invoices
Service-charge statements
Legal and professional invoices
Purchase and sale documents
Records of property improvements
Travel records where relevant
Records should be complete, accurate and clearly connected to the relevant property.
Can an accountant guarantee that I will pay less?
No responsible accountant should guarantee a saving before understanding your circumstances.
The accountant’s job is to apply the rules correctly, claim available expenses and reliefs where appropriate, keep submissions accurate and help you make informed decisions.
Can I change accountants during the year?
Yes. You do not normally need to wait until the end of the tax year. The new accountant should explain the handover process, request the necessary records and check upcoming deadlines.
