Property Income Allowance Calculator: Is Your Rent £1,000 Tax-Free? (2026/27)
Last updated 24 June 2026 · 8 min read · By the LandlordTaxAi Editorial Team
The short answer
Every individual gets a £1,000 property allowance — gross rental income up to £1,000 a year is tax-free and usually doesn’t even need declaring. Above £1,000 you can deduct the allowance instead of your actual expenses, whichever leaves you better off. The calculator above shows which option wins.
If you earn a small amount from property — a driveway let, a storage space, the odd short let — you may owe no tax at all thanks to the £1,000 property allowance. And even if you earn more, the allowance can beat claiming your real expenses when your costs are low.
The calculator above compares both routes for 2026/27 so you don’t overpay. This guide explains the rules: when the income is fully tax-free, when to claim the allowance instead of expenses, and the traps to avoid.

How the £1,000 property allowance works
The property allowance gives you up to £1,000 of gross property income tax-free each tax year. There are two ways it helps, depending on how much you earn.
If your total property income is £1,000 or less, it’s covered in full — you generally don’t need to tell HMRC or file a return for it (this is called full relief). If you earn more than £1,000, you can choose partial relief: deduct the £1,000 allowance from your income instead of your actual expenses.
| Gross property income | What you can do |
|---|---|
| £1,000 or less | Fully tax-free — usually no need to declare |
| More than £1,000 | Deduct either the £1,000 allowance OR your actual expenses — not both |
| High expenses (e.g. mortgage, repairs) | Usually better to claim actual expenses |
It’s an either/or choice each year. If your real expenses are more than £1,000, claim them. If they’re less, claim the allowance — the calculator above picks the winner for you.
When the allowance beats claiming expenses
The allowance shines when your costs are low relative to your rent. A landlord with £2,500 of income and only £300 of expenses is far better off deducting the £1,000 allowance than their £300 of real costs — it wipes out an extra £700 of taxable profit.
By contrast, a typical mortgaged landlord with thousands in expenses should claim actual costs. You can’t mix the two on the same income source, and you can’t use the allowance at all if you claim certain other reliefs on that income.
You cannot use the property allowance and the Rent a Room scheme on the same income, and you can’t use the allowance against rent from a company you (or a connected person) control. See the Rent a Room scheme for letting in your own home.
How to use the calculator above
The allowance and Making Tax Digital
From April 2026, landlords with qualifying income over £50,000 join Making Tax Digital. Note that MTD thresholds use gross income, so the £1,000 allowance doesn’t change whether you’re in scope — it only affects the tax you ultimately pay.
If your property income is modest and fully covered by the allowance, you’re unlikely to be near the MTD threshold. But if you have other property or trade income that pushes you over, you’ll still report through MTD. See the MTD threshold calculator.
Never overpay on small property income
LandlordTaxAi automatically compares the £1,000 allowance against your real expenses every year and claims whichever saves you more — no spreadsheets, no guesswork.
See how it worksA worked example
Leo rents out a parking space and a storage room, earning £2,400 in 2026/27 with £250 of expenses. He’s a basic-rate taxpayer.
| Gross property income | £2,400 |
| Option A: actual expenses | £2,400 − £250 = £2,150 taxable |
| Option B: property allowance | £2,400 − £1,000 = £1,400 taxable |
| Better option | Allowance (saves tax on £750 more) |
| Tax saved at 20% | £150 |
Because Leo’s expenses are well under £1,000, claiming the allowance leaves £750 less taxable profit than claiming his real costs.
Frequently asked questions
Is the first £1,000 of rental income tax-free?
Yes — every individual has a £1,000 property allowance. If your gross property income is £1,000 or less, it’s tax-free and usually doesn’t need declaring.
Can I claim the allowance and my expenses?
No. For each income source you claim either the £1,000 allowance or your actual expenses — whichever is more beneficial.
Do I need to tell HMRC if I earn under £1,000?
Usually not. Property income within the allowance generally doesn’t need to be reported, though there are exceptions if you’re already in Self Assessment.
Can a couple each use the £1,000 allowance?
Yes. The allowance is per person, so jointly owning landlords each have their own £1,000 against their share of the income.
Can I use the allowance with the Rent a Room scheme?
Not on the same income. Rent a Room (up to £7,500) applies to letting furnished rooms in your own home; the property allowance applies more generally — but not both together.
Does the allowance reduce my MTD threshold?
No. MTD uses gross qualifying income, so the allowance affects your tax bill but not whether you’re mandated into Making Tax Digital.
