Taxation of UK Property Income for ACCA TX-UK

Updated 11 October 2026 · Fact-checked

UK property income is the rent you receive less allowable expenses, taxed as one UK property business. Individuals normally use the cash basis. You can deduct actual expenses or claim the £1,000 property allowance, not both. Individuals' losses are normally carried forward against future property profits. Premiums on short leases are partly taxed as income.

Understand Taxation of UK Property Income

A person who lets out UK land or buildings has a UK property business. All their lettings are treated together as one business. You work out one profit or loss for the tax year, then add the profit to the income tax computation as property income.

For an individual, the default method is the cash basis. You tax rent actually received in the tax year and deduct expenses actually paid in it. Use the accruals basis only where the question says so or where the individual has opted out of the cash basis. Companies always use accruals, because they follow their accounting profit.

Expenses must be incurred wholly and exclusively for the letting. Typical allowable items are letting agent fees, insurance, repairs, council tax paid by the landlord, and loan interest on commercial property. Capital costs, such as an extension or the purchase of the property, are not deductible as expenses. Private use costs are never deductible.

Finance costs for individuals: interest on a loan used for residential property is not deducted in computing the property profit. Instead the individual gets a tax reduction at the basic rate of 20% of the finance costs. In broad terms this is limited by the property profits and by income above the personal allowance. Interest on commercial property is still a deductible expense.

You can choose between actual expenses and the property allowance. The allowance is £1,000 of property income. Choose the larger of £1,000 and your actual expenses. If you claim the allowance, you deduct no actual expenses at all. You cannot claim it together with actual expenses. It is not available to companies, or where rent-a-room relief applies to the same income.

If a lease is granted for 50 years or less and a premium is received, part of the premium is taxed as property income. The income element is taxed in the year the lease is granted. The rest is a capital gain. Furnished lettings no longer get a wear and tear allowance. Instead you can claim the cost of replacing furniture and household items, but not the cost of the first purchase.

For an individual, a property loss is normally carried forward against future property profits. A company's UK property business loss can be set against its total profits.

Key rules to remember

Property profit: Property profit = Rent taxable in the period − allowable expenses; For individuals, use cash received and paid by default. For companies, use accruals. For individuals, residential finance costs are not an expense here. They give a 20% tax reduction instead.
Property allowance: Deduction = the larger of £1,000 and actual expenses; If you claim the allowance, no actual expenses are deducted. You cannot claim both. It is not available to companies or where rent-a-room relief applies to the same income.
Premium on a short lease: Income element = Premium × (51 − n) ÷ 50, where n is the lease length in years; Applies where the lease is 50 years or less. The income element is taxed as property income in the year the lease is granted. The remainder of the premium is a capital gain.
Capital part of premium: Capital part = Premium − income element; Valid for leases of 50 years or less. Use part disposal rules for the capital part, treated as the disposal of an interest in the land. The income element is taxed in the year the lease is granted.
Property loss: Individual: loss carried forward against the first available future property profits. Company: UK property business loss set against total profits; A loss on one letting is set against profits from other lettings in the same year first.

How to solve Taxation of UK Property Income questions

Use this order for any property income question. It keeps the marks for each stage and stops you missing a trap.

1Identify the taxpayer. An individual uses the cash basis by default. A company uses accruals. Read the question for any stated opt-out.
2List the rent received or receivable for the tax year. Time apportion if a property was let for part of the year.
3Add any taxable element of a lease premium, using the formula, if the lease is 50 years or less.
4List the expenses actually paid (or accrued, if using accruals). Remove capital items and private use. For an individual, also remove interest on residential property loans, which is relieved by a tax reduction instead.
5For a furnished letting, allow replacement of furniture and household items but not the first purchase.
6Compare total actual expenses with the £1,000 property allowance. Use the larger deduction, if the allowance is available (not for a company, and not where rent-a-room relief applies to the same income). Do not claim both.
7Calculate the profit or loss. Set any loss against other property income of the same year. An individual carries forward the rest against future property profits. A company can set its UK property business loss against total profits.
8Put the profit into the income tax computation as non-savings income, taxed at the normal rates. Then deduct the 20% tax reduction for any residential finance costs.

Quickest way: Rent, premium, expenses, allowance check

When to use it: Use this in a three-mark or objective test question where you need the property profit fast.

Write the rent for the year, and add any premium income element.
Subtract only the allowable revenue expenses. Leave out residential finance costs for an individual.
Check: are the expenses over £1,000? If not, and the allowance is available, deduct £1,000 instead and no expenses.
For an individual, treat a negative result as a loss to carry forward, not a deduction against other income.

Common mistakes in Taxation of UK Property Income

Claiming both the £1,000 property allowance and actual expenses.
Students treat the allowance as an extra relief.
Fix: Choose one. Compare actual expenses with £1,000 and use the larger deduction. The allowance is not available to companies or where rent-a-room relief applies to the same income.
Deducting capital costs such as an extension or the cost of buying the property.
The cost is related to the let property, so it feels allowable.
Fix: Only revenue expenses are deductible. Improvements are capital. Repairs restoring the property to its former state are revenue.
Using accruals for an individual when the question gives no opt-out.
Students copy the rules used for companies or trades.
Fix: Default to the cash basis for individuals: rent received and expenses paid in the tax year.
Deducting the first purchase of furniture in a furnished letting.
Students remember the old wear and tear allowance.
Fix: Claim only the cost of replacing items. The initial furnishing cost is capital.
Setting an individual's property loss against general income.
Students mix property losses with trading loss reliefs.
Fix: An individual's property loss is normally carried forward against future property income only (after same-year set-off against other lettings). Only a company can set its UK property business loss against total profits.
Taxing the whole lease premium as income.
Students forget the formula splits the premium.
Fix: Use Premium × (51 − n) ÷ 50 as income and treat the rest as capital.

Worked examples

Example 1

Ravi owns two let flats in the UK. In 2025/26 he received rent of £14,800. He paid agent fees of £1,480, insurance of £420, repairs of £900 and spent £6,000 on an extension to one flat. All are paid in the year. Calculate his property income using the cash basis.

Show the solution

Rent received: £14,800.
Allowable expenses: agent fees £1,480 + insurance £420 + repairs £900 = £2,800.
The extension of £6,000 is capital, so it is not deductible.
Actual expenses of £2,800 exceed the property allowance of £1,000, so use actual expenses.
Property profit: £14,800 − £2,800 = £12,000.

Answer: Ravi's property income is £12,000.

Example 2

Nadia grants a 21-year lease of a shop to a tenant and receives a premium of £50,000. Calculate the amount taxed as property income.

Show the solution

The lease is 21 years, which is 50 years or less, so part of the premium is income.
Income element = £50,000 × (51 − 21) ÷ 50.
= £50,000 × 30 ÷ 50 = £30,000.
The remaining £20,000 is dealt with as a capital gain.

Answer: £30,000 is taxed as property income. The other £20,000 is within the capital gains computation.

Exam tips

Look at the taxpayer first. Individual means cash basis, company means accruals, and a stated opt-out changes the answer.
Always compare expenses to the £1,000 property allowance when expenses look small. Take the larger deduction, and remember the allowance means no actual expenses. The examiner likes this trap.
For an individual, do not deduct interest on a residential property loan. Give a 20% tax reduction instead. Interest on commercial property is deductible.
Set out each expense as an allowable or not allowable list. Marks are given for the reason why an item is excluded.
For objective test questions, check the lease length and use the formula with care. The wrong value of n is the common slip.
State a loss clearly. An individual carries it forward against future property profits. A company can set a UK property business loss against total profits.

Taxation of UK Property Income: frequently asked questions

What is the difference between the cash basis and the accruals basis for property income?

The cash basis taxes rent actually received and deducts expenses actually paid in the tax year. The accruals basis taxes rent due and deducts expenses incurred in the period, whether paid or not. Individuals usually use cash basis, and companies use accruals.

Should I use the £1,000 property allowance or actual expenses?

Use whichever gives the larger deduction. If actual expenses are below £1,000, claim the allowance. If they are higher, deduct the actual expenses. You cannot claim both, and claiming the allowance means no expenses are deducted. It is not available to companies or where rent-a-room relief applies to the same income.

How are property business losses relieved?

A loss is first set against other UK property income of the same year. For an individual, any remaining loss is normally carried forward against the first available future property profits. A company can set its UK property business loss against its total profits.

How is a premium on a short lease taxed?

If the lease is 50 years or less, part of the premium is taxed as property income using Premium × (51 − n) ÷ 50. This income element is taxed in the year the lease is granted. The rest is treated as a capital gain.

Can an individual deduct mortgage interest on a let property?

Interest on a loan for residential property is not deducted in computing the property profit. The individual instead gets a tax reduction at 20% of the finance costs. Interest on commercial property is a deductible expense.
