Where UK property is a source of rental or other income, the taxpayer is liable for self-assessment (i.e., must file a tax return) if their situation meets any of the following criteria:
- Total property income exceeds £1,000: This includes all UK rental income, receipts from land or property, furnished holiday lettings (FHL) in the UK or EEA (unless remittance basis applies), furnished rooms in your home, lease premiums, or reverse premiums. Income up to £1,000 qualifies for the property income allowance and is exempt from tax and reporting. If over £1,000, you must report it unless you qualify for an exemption (e.g., Rent a Room relief up to £7,500/£3,750 if joint).
- Claiming the property income allowance but income exceeds £1,000: You must file to claim the allowance (up to £1,000 total across all property businesses, including foreign). You cannot claim if income is from a connected party (e.g., relative or employer).
- Claiming Rent a Room relief where income exceeds £7,500 (£3,750 if joint): If letting furnished rooms in your home and income exceeds the threshold, you must file and either pay tax on the excess or calculate profit after expenses.
- Non-resident landlord status: Even if income is below thresholds, you must file if claiming back tax deducted under the non-resident landlord scheme.
- Claiming reliefs, allowances, or losses: This includes:
- Deducting allowable expenses or capital allowances (e.g., if expenses > turnover, to claim losses against future income).
- Foreign Tax Credit Relief on EEA FHL foreign tax.
- Relief for finance costs on residential properties.
- Carrying forward losses from prior years.
- Capital allowances (e.g., Annual Investment Allowance, Structures and Buildings Allowance).
- Period of grace election for FHL properties not meeting qualification days.
- Property business involves partnerships or joint ownership: If property is let jointly and you need to declare your share (or use Form 17 for unequal shares), or if income is from a partnership property business.
- Accounting period changes or transitional adjustments: If switching between cash basis and traditional accounting, requiring adjustments for transitional receipts/expenses.
- Participation in Managing Serious Defaulters (MSD) programme: Requires full reporting, including profit/loss accounts and balance sheets.
- Income from specific sources requiring separation: E.g., FHL must be separated for special rules (capital allowances, reliefs); EEA FHL if not on remittance basis.
- No expectation of future income but cessation in year: If all property income ceased and no future income expected, you may still need to file to confirm.
If you believe you do not need to file (e.g., income ≤ £1,000 or fully exempt under allowances), you must notify HMRC by 31 January 2026 to avoid penalties. Use the online checker at www.gov.uk/check-if-you-need-a-tax-return. Filing deadlines: Paper return by 31 October 2025; online by 31 January 2026.
Note: These criteria assume no other income sources (e.g., employment, self-employment). If other income exists, broader self-assessment rules apply. Property income from overseas (non-EEA FHL) goes in the ‘Foreign’ pages, but total property income (UK + foreign) determines allowance thresholds.
Information Required for Each Box in the Tax Return (UK Property Pages – SA105)
The UK property pages (SA105) are the specific section of the tax return for reporting UK property income. The boxes are divided into UK FHL (furnished holiday lettings) and other UK property income. You must complete relevant boxes based on your income type. If only UK property income triggers self-assessment, focus on these; copy figures to main return (e.g., TR3) as needed. All figures are in £ (pounds sterling), rounded to nearest pound; negative figures (losses) are entered without minus sign where specified.
Always include your full name and Unique Taxpayer Reference (UTR) at the top.

If property income is from a partnership, use ‘Partnership (full)’ pages instead. For tax calculation (SA110), property income feeds into non-savings income (e.g., A28/A29 for profits, M1/M2 for finance costs relief), but these are not direct tax return boxes for property.
