    Airbnb + Short-Term Let Tax — Rent-a-Room £7,500 + Post-FHL Abolition (April 2025)

    Airbnb + similar short-term let income falls into one of three regimes. Lodger in main residence (rent-a-room qualifies): £7,500 annual exempt amount under ITTOIA 2005 Part 7 Chapter 1 (joint owners split £3,750 each). Spare-room or whole-property short-term let NOT meeting rent-a-room: property income; Property Allowance £1,000 partial relief or actual expenses (mutually exclusive with rent-a-room). Whole-property short-term lets used to qualify for Furnished Holiday Letting (FHL) treatment with material benefits (capital allowances, BADR, pension-able profit) — but the FHL regime was ABOLISHED from 6 April 2025 (individuals) / 1 April 2025 (companies). Post-abolition: all short-term lets are ordinary property income, with NRCGT applying for non-residents (TCGA 1992 Sch 1A). Airbnb + Vrbo + similar report seller data to HMRC under OECD MRR from January 2024. VAT registration mandatory above £90,000 turnover.

    In plain English

    Three regimes for short-term let income. Which one applies depends on the property and the arrangement. 1) LODGER IN MAIN RESIDENCE — RENT-A-ROOM. If you let a furnished room in your main home to a lodger (live-in arrangement), rent-a-room relief gives you £7,500 a year exempt from income tax. Joint owners split — £3,750 each, not £7,500 each. Above £7,500 you choose: pay tax on excess (rent-a-room basis) OR file as ordinary property income with actual expenses. Below £7,500 the exemption is automatic; no SA needed for that source alone. 2) SHORT-TERM LET NOT QUALIFYING FOR RENT-A-ROOM. This covers most Airbnb situations: whole-property let, or you-not-resident-during-let arrangements. Property income on SA property pages. Property Allowance £1,000 partial relief or actual expenses (Airbnb commission ~14-16%, cleaning, utilities, insurance, council tax, mortgage interest restricted to 20% basic-rate credit). You cannot combine Property Allowance with rent-a-room. 3) POST-FHL ABOLITION. The Furnished Holiday Letting regime was abolished from April 2025. Before abolition, FHL gave material benefits: full capital allowances on furniture + equipment, profits counted as relevant UK earnings for pension contributions, gains qualified for BADR (10% / 14% from 6 April 2025). Post-abolition: short-term lets are ordinary property income — no FHL capital allowances; profits don't count for pension; gains don't qualify for BADR. NRCGT (TCGA 1992 Sch 1A) applies for non-residents disposing of UK residential property regardless. Transitional rules for losses + capital allowances brought forward — review with a property tax specialist. Airbnb + Vrbo + Booking.com (where it acts as facilitator) report seller data to HMRC under OECD MRR from January 2024. VAT registration mandatory above £90,000 turnover — high-volume short-term let operators frequently caught.

    How it works

    Rent-a-Room — £7,500 in main residence

    ITTOIA 2005 Part 7 Chapter 1 exempts £7,500 of gross rent received from letting furnished accommodation in the host's main residence to a lodger (live-in arrangement). Joint owners (typically couples) split £3,750 each — common misconception is two × £7,500. Below £7,500: automatic exemption; no SA filing on that source alone. Above £7,500: choose 'rent-a-room basis' (tax on excess over £7,500 with no expense deductions) OR opt out and treat as ordinary property income (full expense deductions including mortgage interest restricted credit, council tax proportion, utilities proportion). Election is per year — switch to ordinary basis in years when expenses are high.

    Property Allowance £1,000 — alternative for non-rent-a-room cases

    ITTOIA 2005 ss.783BA-783BR — £1,000 Property Allowance. Mutually exclusive with rent-a-room ON THE SAME PROPERTY (can use Property Allowance on different property income). For occasional Airbnb of a second property, spare room not qualifying as lodger arrangement, or parking-space let — Property Allowance often the only relief. Below £1,000 gross: full relief; no income tax; no SA on that source alone. Above £1,000: choose partial relief (£1,000 deemed deduction) OR actual expenses.

    Whole-property short-term let — ordinary property income

    Property income on SA property pages. Income: gross rent received (REPORT GROSS — claim Airbnb commission as expense). Allowable expenses: Airbnb commission (typically 14-16% + payment processing); cleaning fees; utilities (proportional for periods let); council tax (proportional); insurance (incl host insurance + buildings); repairs + maintenance; advertising; agent fees. Mortgage interest restricted to 20% basic-rate tax credit per ITTOIA 2005 s.272A (the 'Section 24' restriction — see Section 24 page). Capital allowances on furniture + equipment removed by ITTOIA 2005 s.308A (no plant + machinery capital allowances on residential rental property — replacement of domestic items relief available instead).

    FHL abolition from April 2025 — what changed

    FHL regime was a favourable treatment for short-term holiday lets meeting qualifying criteria (210 days available + 105 days actually let + max 31-day average let). Pre-abolition benefits: full capital allowances on furniture (instead of replacement of domestic items relief); profits as 'relevant UK earnings' for pension contributions; gains qualifying for BADR (10% pre-April 2025 / 14% from 6 April 2025 / 18% from 6 April 2026); Class 2 NIC available; Class 4 NIC + tax-deductible interest with no s.272A restriction. Abolition F(No.2)A 2024 effective 6 April 2025 (individuals) / 1 April 2025 (companies). Post-abolition: ordinary property income; no capital allowances; profits don't count for pension; no BADR on gains. Transitional rules: existing capital allowance balances continue to be written down (no new claims); losses brought forward usable against future property profits; FHL-status disposals before April 2025 still qualify for BADR on gain.

    NRCGT for non-residents

    TCGA 1992 Schedule 1A imposes NRCGT on non-residents disposing of UK residential property regardless of FHL status. Pre-FHL-abolition NRCGT applied alongside FHL gains anyway for non-residents. Post-abolition the picture is unchanged for non-residents — NRCGT on disposal, 60-day reporting + payment via the Property Disposal return. UK residents not affected by NRCGT (subject to normal CGT rules on residential property — 18% / 24% from 6 April 2024 + AEA £3,000).

    OECD MRR reporting + VAT registration

    Airbnb + Vrbo + Booking.com (as facilitator) report seller data to HMRC under OECD MRR from 1 January 2024 with first reports January 2025 for 2024 calendar data. De minimis 30 transactions OR €2,000 — most active Airbnb hosts above. CONNECT cross-references against SA from 2025/26. VAT: registration mandatory above £90,000 UK turnover. High-volume short-term let operators (multiple properties + year-round occupancy) caught — analyse Flat Rate vs standard scheme. Single-property casual Airbnb hosts almost always below.

    Common mistakes + traps

    Worked example

    Niamh, Edinburgh flat owner — let on Airbnb part-year while she travels for work

    2025/26: Niamh's main residence Edinburgh flat. She travels for work + lets the whole flat on Airbnb for 88 nights at average £85/night = £7,480 gross. Airbnb commission £1,047 (14%). Cleaning fees £710. Utilities + council tax let-period proportion £620. Insurance host upgrade £180. Wear-and-tear / replacement of domestic items £180 (kettle + bedding). Mortgage interest let-period proportion £840. Niamh is not resident-during-let so rent-a-room doesn't apply (no lodger; she's away).

    1. Step 1 — Regime: whole-property let with no live-in lodger = property income (not rent-a-room). Property Allowance £1,000 partial relief or actual expenses.
    2. Step 2 — Actual expenses: commission £1,047 + cleaning £710 + utilities £620 + insurance £180 + replacement £180 = £2,737 (before mortgage interest).
    3. Step 3 — Mortgage interest restriction (s.272A): mortgage interest NOT deductible from rental income — instead 20% basic-rate credit. £840 × 20% = £168 tax credit.
    4. Step 4 — Trading Allowance partial vs actual: actual expenses £2,737 > £1,000 — actual wins.
    5. Step 5 — Property income profit: £7,480 − £2,737 = £4,743.
    6. Step 6 — Income tax on property profit: assume Niamh's other income uses Personal Allowance. £4,743 at 20% basic = £948.60.
    7. Step 7 — Mortgage interest credit: £948.60 − £168 = £780.60 income tax payable on property income.
    8. Step 8 — FHL status: Niamh's let does not meet FHL qualifying criteria pre-abolition (88 nights < 105 minimum) so FHL was never available. Post-abolition makes no difference for her.
    9. Step 9 — OECD MRR + CONNECT: Airbnb reports £7,480 gross + Niamh's NI number to HMRC January 2026. SA filing prevents enquiry.

    Outcome: £780.60 income tax on property profit. Property Allowance partial relief would have given £6,480 taxable vs £4,743 actual — actual wins. Mortgage interest restricted to basic-rate credit per s.272A.

    Frequently asked questions

    What happens if I miss the Self Assessment deadline?+
    The Self Assessment deadline is 31 January (online filing) for the previous tax year. Miss it and HMRC apply an automatic £100 penalty. Beyond that: £10 per day from 3 months late (capped at £900), 5% of tax due at 6 months late, and another 5% at 12 months late, under Schedule 55 of the Taxes Management Act 1970. If you have a genuine reason (serious illness, bereavement, technical issue with HMRC's systems) you can appeal with evidence; HMRC accepts reasonable excuse appeals in most genuine cases.
    Do I need an accountant or can I file Self Assessment myself?+
    Legally you can file Self Assessment yourself via gov.uk for free, most simple sole-trader returns (single income source, basic expenses) are realistic to self-file. An accountant adds real value when: your trading profit is above £40,000 (extraction-strategy decisions matter), you have multiple income streams (PAYE + self-employment + property + dividends), you've crossed the £90,000 VAT threshold, you're considering incorporation, or you have an HMRC enquiry. Expect to pay £400-£1,500/year for a typical sole-trader accountant; the cost is itself a deductible expense.
    How do payments on account work?+
    When your Self Assessment tax bill exceeds £1,000 for the first time, HMRC requires payments on account toward NEXT year's tax. Half the current bill is due 31 January (alongside the current bill); the other half is due 31 July. So your first January after crossing the threshold can hit with a double-bill: last year's balance + first payment on account. Adjust via Form SA303 if you expect next year's income to drop substantially. Payments on account don't apply if more than 80% of your tax is collected via PAYE.
    If I rent my spare room to a long-term lodger, can I use rent-a-room?+
    Yes — rent-a-room is for the lodger in main residence regardless of platform (Airbnb, SpareRoom, direct). £7,500 annual exempt; joint owners split £3,750 each.
    What about my Section 24 mortgage interest credit on Airbnb income?+
    Section 24 (ITTOIA 2005 s.272A) restricts mortgage interest to a 20% basic-rate tax credit on residential property income. Applies to ordinary property income (post-FHL abolition includes short-term lets). The credit reduces tax payable but doesn't reduce taxable income.
    Can I still claim FHL benefits for 2024/25?+
    Yes — FHL regime ran until 5 April 2025 (individuals) / 31 March 2025 (companies). Final FHL year is 2024/25. Transitional rules for capital allowance balances + losses carried into post-abolition property regime.
    What's the position for council tax + small business rates on Airbnb?+
    If your short-term let meets the criteria, you may be liable to business rates instead of council tax. From April 2023, England rules require 70 nights actually let + 140 nights available + meet local-authority registration; Wales similar; Scotland separate licensing regime. Below criteria = council tax (often with second-home premiums). Above criteria = business rates (which may benefit from Small Business Rate Relief). Check with local council.
