Landlord Tax Accountant Bournemouth: Rental Income, Expenses and Property Tax Guide

A landlord generally pays tax on the profit made from renting out property. Profit is calculated by adding relevant rental income and deducting the expenses or allowances that may be claimed. The amount of tax payable also depends on the landlord's wider personal circumstances.

Rental income can include:

Where a person rents out more than one UK property, the profits and losses from those properties are generally combined into one UK property-business result. Overseas-property profits and losses are kept separate from UK property.

Different rules can apply to:

A property allowance of up to £1,000 may be available to an individual with qualifying property income. Where annual gross property income from one or more property businesses is £1,000 or less, the income may not need to be reported, although exceptions apply and a return may still be required for another reason.

If your gross property income is more than £1,000, check the current reporting requirements using the official GOV.UK Self Assessment and property-income guidance. The appropriate treatment can depend on the allowance, actual expenses, residential finance costs, losses, joint ownership and whether you are already required to submit a tax return.

Do not assume that only the profit paid into your bank account needs to be considered. Start with the gross rental income and maintain records supporting the relevant costs and allowances.

HM Revenue & Customs requires accurate records of rent received and expenses incurred when working out property profit.

Do not rely only on the net amount transferred by a letting agent. The statement may contain rent, management fees, repair deductions and other adjustments that should be recorded separately.

Allowable expenses generally need to be connected with the property-rental business rather than the landlord's private use or the initial acquisition of the property.

Depending on the facts, relevant expenditure may include:

The correct treatment depends on what was purchased, why the cost was incurred and whether it was a repair, replacement, improvement, finance cost or capital expenditure.

An expense can be commercially sensible without necessarily being immediately deductible from rental income.

One of the most common landlord-tax problems is treating every building cost as a repair.

A repair generally restores an asset or property, while an improvement may create something new or enhance the property beyond its previous condition. The full facts matter, including:

For individual landlords of residential property, finance-cost relief is restricted to the basic rate of Income Tax. From 2020/21, the finance-cost restriction is fully in place, with qualifying costs dealt with through a basic-rate tax reduction rather than deducted in full when calculating property profit.

Relevant finance costs can include mortgage interest and certain costs associated with obtaining or repaying loans. Capital repayments of a mortgage or loan do not receive relief as a finance cost.

The basic-rate reduction cannot be used to create a tax refund. Depending on property-business profit and adjusted total income, unused restricted finance costs may be carried forward.

This area is frequently misunderstood. A mortgage payment shown on a bank statement may include both capital and interest. The complete payment must not automatically be treated as an allowable expense.

Different rules can apply to companies, commercial or mixed-use property, trusts and some partnership arrangements, so those situations should be reviewed separately.

The amount of rental income taxed on an owner depends on their interest in the property and the relevant ownership arrangements.

For married couples and civil partners who live together, jointly owned property income is usually taxed in equal shares. Where the beneficial ownership and entitlement to income are in unequal shares, different treatment can apply where the relevant conditions and declarations are satisfied.

Where property is owned jointly with someone who is not a spouse or civil partner, the rental result is usually allocated according to the ownership share unless a different allocation has been agreed.

Do not change the tax split using only an informal spreadsheet entry. The legal and beneficial ownership, entitlement to income and supporting evidence should be examined.

A property allowance of up to £1,000 may be available for qualifying property income.

However, using the allowance instead of actual expenses is not automatically the best result. The correct comparison may depend on:

The property allowance is optional and may not produce the best result in every case. It also interacts with the residential finance-cost rules. A landlord with finance costs, losses or brought-forward amounts should compare the available treatments before making a claim.

This should be reviewed from the complete figures rather than chosen solely because the allowance appears simpler.

From 6 April 2026, Making Tax Digital for Income Tax applies to a sole trader or landlord who is registered for Self Assessment, receives qualifying self-employment or property income, is not exempt and had qualifying income above £50,000 for 2024/25. Further published thresholds are above £30,000 for 2025/26, leading to entry from 6 April 2027, and above £20,000 for 2026/27, leading to entry from 6 April 2028.

Qualifying income generally combines gross income before expenses from self-employment and property. Taxpayers remain responsible for checking their position even if they do not receive a letter from HM Revenue & Customs. The treatment of joint property, residence, ceased income sources and unusual arrangements may require a separate review.

For a jointly owned property, an individual's share of the property income counts towards their qualifying income. The HM Revenue & Customs example describes a property producing £50,000 that is owned equally by two siblings. Each person has £25,000 of qualifying income where neither has self-employment income.

The Income Tax ownership treatment and MTD qualifying-income test should each be checked carefully. Do not assume that the gross rent for the complete property belongs wholly to one owner.

Selling or transferring a rental property can create a Capital Gains Tax reporting obligation.

Where Capital Gains Tax is due on the sale of UK residential property, the gain normally must be reported and the tax paid within 60 days of completion. A person already registered for Self Assessment may also need to report the disposal on their return.

If you are considering a sale, speak to an adviser before completion where possible. Useful information may include:
