Property income and investments
Finance Act 2025 · 2025/26
1 Property receipts and basis
In this TX lecture: Residential property finance-cost restrictions and the related tax reducer, and detailed ISA investment limits, are not examined in FTX.
Joint rental property: spouses or civil partners living together who jointly own a let property (not through a partnership) are normally taxed on equal shares of its net rental income. Where their beneficial ownership and income interests are unequal and correspond, both can submit a valid Form 17 declaration to HMRC to use those actual shares instead. They cannot simply choose an arbitrary income split.
2 Property Income
The following income is liable to assessment as property income:
rents received/receivable under any lease or tenancy agreement
premium received on the grant of a short lease
2.1 Basis of assessment
Income from different properties are pooled together in a single computation:
Jim bought a property and rented it out for the first time on 1 July 2025. The rent of £6,000 per annum is paid alternatively (1) quarterly in advance on the first day of the quarter, or (2) quarterly in arrears on the last day of the quarter.
He paid allowable expenses of £300 in November 2025 for redecoration and £500 in May 2026 for repairs completed in March 2026.
(a) Calculate Jim's property income assessment for 2025/26.
(b) What would the assessment be if Jim elected to use the accruals basis?
Show answerHide answer
Under the cash basis use rents received less allowable expenses paid. A property business normally uses the cash basis if annual receipts do not exceed £150,000, unless it elects for accruals. Above £150,000 use accruals. Under accruals use rent earned and expenses incurred for the tax year.
For a lease premium on a short lease use: taxable property receipt=premium×(51−number of complete lease years)/50. The remainder is capital. The grant of a sublease premium is outside FTX.
3 Allowable expenses and replacement items
3.1 Allowable deductions
Allowable property revenue expenditure must relate wholly and exclusively to the rental business.
Land, buildings and improvements are capital expenditure. Apply the specific cash-basis and replacement-item rules below rather than treating every capital payment alike.
Capital allowances are available on cars, and actual motor expenses are deductible when paid. Alternatively, use the HMRC approved mileage allowance:
First 10,000 miles @ 45 p
Over 10,000 miles @ 25 p
If residential lettings are either partly or fully furnished, tax relief is usually given for the furniture and furnishings by way of Replacement of Domestic Items Relief. There is NO relief for the initial cost of furniture and furnishings. There is ONLY relief when assets are replaced. This will include furnishings such as carpets and curtains, electrical equipment such as TVs, fridges, freezers and washing machines and even cutlery and crockery.
The amount of relief is reduced by any proceeds from selling the old asset which has been replaced and relief is not given for any cost which represents an improvement, for example, if a fridge is replaced with a fridge freezer, only the cost of an equivalent fridge qualifies for relief.
Relief is available for allowable expenditure incurred before letting commenced, under the pre-trading expenditure rules; ie expenditure incurred up to 7 years prior to renting is treated as being incurred on the first day of the letting business.
Sid owns a furnished property that is let out at an annual rent of £9,600, payable monthly in advance on the first day of the month.
During the year 2025/26 he made the following payments:
May 2025 | Construction of a garage, replacing the car port | £2,000 |
June 2025 | Insurance for year from 1 July 2025 (insurance for the previous year to 30 June 2025 was £420 paid in June 2024) | £480 |
November 2025 | Drain clearance | £380 |
January 2026 | New Cooker with integrated microwave oven replacing a cooker sold for £50 (a replacement cooker would have cost £300) | £550 |
Redecoration of the property costing £750 was completed in March 2026, although Sid did not pay the decorator until May 2026.
The tenant vacated the property during June 2025 without having paid the rent due for June. Sid was unable to trace the defaulting tenant, but managed to let the property to new tenants from 1 July 2025.
Calculate Sid's property income assessment for 2025/26.

Insurance, letting-agent fees, cleaning, gardening, repairs and other wholly business revenue expenses can be deductible. Improvements are capital. Restrict expenses for private use.
Under the cash basis qualifying plant/equipment costs other than cars may be deductible directly. Cars use capital allowances or the permitted business mileage method. Residential-property finance-cost restrictions are outside FTX.
4 Property losses
If total expenses exceed total income, the property income assessment is nil and the excess property loss is carried forward and offset against future property income profits only.

5 Rent a room relief
If an individual lets a furnished room or rooms in his or her main residence as living accommodation then rent received up to £7,500 p.a. is exempt.
The exemption may be ignored if the taxpayer wants to generate a loss where expenses exceed income, or where actual expenses exceed £7,500.
If rent received exceeds £7,500 p.a. the tax payer may choose to assess as follows:
Ordinary calculation (cash basis)
Rent received | X |
Less: expenses paid | (X) |
Property Income | X |
Alternative calculation (election)
Rent received | X |
Less: rent a room relief | (7,500) |
Property Income | X |
The election for 2025/26 must be made by 31 January 2028 and stays in force until it is revoked.
