If you earn money from letting out property in the UK, you are legally required to declare your rental income to HMRC. Many landlords find this process confusing, especially when it comes to expenses, allowances, and deadlines.
At JSR, we are an accountancy practice specialising in landlord and property tax. We work with landlords across the UK to ensure rental income is reported correctly and that every allowable deduction is claimed, so you never pay more tax than necessary.
Do I Need to Declare Rental Income?
Yes. If your total rental income exceeds £1,000 per year (the property allowance), you must declare it to HMRC—even if you make little or no profit.
This applies if you:
- Own a buy-to-let property
- Let out multiple properties
- Rent out a room in your own home
- Earn income from short-term lets (e.g., Airbnb)
- Share rental income with a joint owner (each person must declare their share)
At JSR, our accountants ensure all your property income is declared correctly, keeping you fully compliant with HMRC rules.
How to Declare Rental Income
Rental income is declared through a Self Assessment tax return. To do this, you need to:
- Register with HMRC for Self Assessment
- Keep records of all rental income and expenses
- Complete the property pages of the tax return (SA105 form)
- File before the deadline: 31 January (online) or 31 October (paper)
Our team at JSR handles the full process for landlords—from registration through to submission—so you can focus on managing your property, not the paperwork.
Allowable Expenses Landlords Can Claim
Landlords only pay tax on their profits, not their full rental income. You can deduct a range of allowable expenses, such as:
- Mortgage interest (relief given as a 20% tax credit)
- Repairs and maintenance (not improvements)
- Letting and management fees
- Insurance premiums
- Council tax, utilities, and service charges (if paid by you as landlord)
- Accountant and legal fees relating to the rental business
At JSR, our accountants make sure you claim every legitimate deduction, maximising your tax efficiency.
Rent a Room Scheme
If you rent out a furnished room in your main home, you may be eligible for up to £7,500 per year tax-free under the Rent a Room Scheme.
We advise clients whether this scheme, or the standard property allowance, is more beneficial for their situation.
What If You Don’t Declare Rental Income?
Failure to declare rental income can lead to:
- Backdated tax bills with interest
- Financial penalties
- HMRC investigations
HMRC’s Let Property Campaign offers landlords the chance to disclose undeclared rental income voluntarily, often with reduced penalties. At JSR, we assist landlords in making disclosures and negotiating the best possible outcome.

Yes. Even if your rental property runs at a loss, you must still declare the income and expenses to HMRC. Losses can often be carried forward to offset against future rental profits.
What happens if I don’t declare rental income in the UK?
HMRC can issue penalties, charge interest, and investigate your tax affairs. Voluntary disclosure through the Let Property Campaign can reduce penalties.

Absolutely. An accountant can prepare your Self Assessment tax return, ensure you claim all allowable expenses, and provide tax planning advice to minimise your liability.
How much rental income is tax-free in the UK?
You can earn up to £1,000 per year tax-free under the property allowance. If you rent a room in your home, the Rent a Room Scheme may allow up to £7,500 tax-free.
When is the deadline to declare rental income?
For online returns, the deadline is 31 January following the end of the tax year. For paper returns, the deadline is 31 October.
