The driveway ledger: taxing spare rooms, parking bays and hired-out cars in 2026

The household balance sheet has changed. A spare room can become a short-term let, a driveway can become a parking bay, and a car can become a rental asset through a platform. The income is real, but the tax label is not always the one the platform uses. For 2026, the key question is what is being let: furnished living accommodation in your main home, land, or a vehicle used in a commercial arrangement. Each points to a different allowance and a different record-keeping habit.
Rent a Room is narrower than it sounds
The £7,500 Rent a Room allowance is often treated as a general exemption for anyone who lets property. It is not. It applies to furnished accommodation in your only or main home, and you must live there. It does not cover a whole flat you do not live in, a second home, or a parking space. The relief is designed for genuine home-sharing, not for a property portfolio.
If your gross rent is within the limit, the income is generally exempt and you do not need to report it unless you have another reason to file a return. If two people receive the rent, the limit is shared, normally £3,750 each. Above the threshold, you choose between the £7,500 allowance and your actual allowable expenses. You cannot deduct expenses as well as claiming the allowance.
A simple comparison helps. Priya lets a furnished room in her home for £8,400 in the year. Using Rent a Room, the taxable amount is £900. If her allowable expenses are £1,200, her actual profit is £7,200, so the allowance is better. If her expenses were £7,800, her actual profit would be £600, so claiming expenses would be better. The correct answer depends on the figures, not on habit.
Driveways are property income, not home-sharing relief
Renting a parking space is income from land. Rent a Room does not apply. The £1,000 property allowance may apply instead. If your gross property income is £1,000 or less, you generally do not need to report it or pay tax on it. Above that level, you can deduct the £1,000 allowance instead of actual expenses, provided you do not claim both.
Tom receives £1,800 from letting his driveway. The platform charges £180 and his insurance costs £60, leaving an actual profit of £1,560. Using the property allowance, his taxable amount is £800. On those figures, the allowance is the better route. If his expenses were £1,100, his actual profit would be £700, which would beat the allowance. The property allowance is a useful simplification, not always the best result.
One common error is to stack allowances. The £1,000 property allowance cannot be used on top of Rent a Room relief for the same income. Nor is it a trading allowance. It applies to property income, and it is a total across your property lettings rather than a fresh £1,000 for each driveway or room.
When a car is a business, not a hobby
Hiring out a car through a platform can be more complicated. A one-off arrangement may be miscellaneous income. A regular, organised activity with commercial intent may be trading. The distinction matters because the £1,000 trading allowance applies to trading income, not to rental income from land. If you use the trading allowance, you cannot also deduct expenses.
A car is not a room, and it is not a parking space. Do not assume the property allowance applies simply because the vehicle is kept at your home. Keep the platform statements, the rental dates, the mileage, cleaning costs, insurance, repairs, MOT and servicing records. If the activity becomes regular, take advice on whether it is trading and how National Insurance may apply.
The records that make the difference
Platforms usually provide a gross figure and a net payout. HMRC is interested in the gross income before platform fees, with allowable expenses claimed separately. Keep the statements, the dates of each letting, occupancy records, insurance documents and a mileage log where a vehicle is involved. If you claim actual expenses, retain the receipts. If you use an allowance, note why it was the better choice.
You may need to register for Self Assessment by 5 October after the end of the tax year. The online return is normally due by 31 January. If the tax is substantial, payments on account may follow. A platform statement is a starting point, not a tax return, and digital reporting by a platform does not settle your tax position.
Myths to retire
Rent a Room does not cover every Airbnb-style letting. The £1,000 property allowance does not stack with the £7,500 allowance. The trading allowance is not a universal £1,000 deduction for any casual income. Cash or platform income does not become invisible because it arrives in small amounts. The calm approach is to identify the income correctly, keep the records, and claim only the relief that fits the facts.
