Direct answer
Landlords may be able to deduct costs that are wholly and exclusively for renting out the property, but the rules depend on the type of cost and the facts.
What this means in practice
- Keep evidence for repairs, agent fees, insurance, services and professional costs.
- Capital improvements are not the same as ordinary repairs.
- Mortgage finance treatment needs care.
The best next step is usually to gather the facts before asking for advice: income, expenses, dates, software, previous returns and any HMRC letters. That gives an accountant something concrete to review.
What to prepare before speaking to an accountant
- Receipts and invoices for each cost.
- Dates and description of work done.
- Photos or notes for repairs versus improvements.
- Agent and service charge statements.
- Mortgage interest and finance documents.
Examples of how the answer can change
Ordinary costs of running the rental business may be easier to assess when they clearly relate to letting the property and are supported by invoices.
Costs become harder where work improves the property, has mixed personal use, relates to finance, spans more than one property, or happens around buying or selling.
The useful pattern is to separate facts from judgement. Facts are things like dates, turnover, software, invoices, bank statements, ownership and deadlines. Judgement is where a rule has to be applied to those facts. The more judgement involved, the more valuable a focused accountant conversation becomes.
How to use this guide before you speak to anyone
Keep invoices, dates, descriptions of the work, photos where useful, agent statements and notes explaining why the cost related to the rental property.
Then write down the decision you are trying to make in one sentence. For example, you might be trying to decide whether to file yourself, change software, register for VAT, switch accountant or clean up records before a deadline. A clear question helps an accountant respond more usefully and helps you compare answers from different providers.
Do not treat the first call as only a price check. Use it to test whether the accountant understands the situation, can explain the next step in plain English and can tell you what information they need before giving a firm view.
How to compare your options
It usually helps to compare three routes: doing it yourself, using software or bookkeeping support, and speaking to an accountant. The right route depends on the risk of getting it wrong, how much time you have, whether deadlines are close and whether the answer affects future tax or compliance.
DIY can be sensible when records are tidy, the rules are easy to check and the financial impact is modest. Software can help when the main issue is organisation, recurring transactions or digital records. Accountant support becomes more useful when interpretation, judgement, deadlines or business structure are involved.
When comparing accountants, ask for the scope in writing. A good comparison should tell you what is included, what is excluded, who will do the work, how quickly they respond, what records they need and whether they understand your business type.
A quick quality check before you decide
- Can you explain the issue in one sentence
- Do you have evidence for the figures or records involved
- Have you checked the official guidance linked on this page
- Would a mistake create penalties, extra tax, missed deadlines or messy records next year
- Do you know what you want an accountant to answer
If several of those answers are unclear, the next step is not necessarily a long engagement. It may simply be a short accountant conversation to confirm the right route and avoid building the rest of the year on a weak assumption.
What this guide is focusing on
Use this guide if you are a landlord trying to turn rent, agent statements, repairs and ownership details into records an accountant can actually use. For What expenses can landlords claim, focus on how the rule meets the records, thresholds, software and decisions you actually have in front of you.
What figure, record or decision should you pin down?
Pin down rent by property, ownership share, agent deductions, repairs versus improvements, finance costs, deposits and whether MTD changes the record process. That gives an accountant something specific to check and stops the conversation becoming a vague discussion about tax in general.
Records to gather
- rent by property
- agent statements
- repair and maintenance invoices
- mortgage interest or finance cost statements
- ownership share and deposit records
Real examples for this situation
- A one-property landlord with agent statements may mainly need to separate rent from deducted fees.
- A jointly owned property needs the income share and expense share recorded clearly before a return is prepared.
- An HMO or student let can create more repairs, deposits and utilities, so the transaction volume matters as much as the rent total.
A common mistake is using net rent received as the whole story and losing the deductions behind it. The safest pattern is to write down the figure, source, date and evidence before deciding whether DIY, software or accountant support is enough.
When to speak to an accountant
Speak to an accountant before claiming if the cost improved the property, has mixed personal use, relates to finance, or could be treated as capital.
Questions to ask an accountant
- Is this a repair or an improvement
- Is this cost wholly for the rental business
- How should finance costs be recorded
- What evidence would HMRC expect
- How should costs be split between properties or owners
Mistakes to avoid
- Assuming every property cost is deductible.
- Losing evidence for repairs.
- Mixing personal and rental costs.
- Forgetting that timing and capital treatment can matter.
Key takeaway
Landlords may be able to deduct costs that are wholly and exclusively for renting out the property, but the rules depend on the type of cost and the facts. If the facts are not simple, use this as a prompt for a proper accountant conversation rather than a final personal answer.
