Landlord Tax UK: Paying Tax on Rental Income

Quick answer: UK landlords pay landlord tax (income tax) on rental profits - not gross rent - at 20%, 40%, or 45% depending on total income. The first £1,000 of rental income is tax-free. Tenants pay council tax, not landlords (unless the property is empty or an HMO). Landlords pay Stamp Duty Land Tax when buying, not tenants. From April 2027, new property-specific landlord tax rates of 22%, 42%, and 47% will apply.

Key Takeaways

• Landlord tax = income tax on rental profits, after deducting allowable expenses
• The £1,000 property allowance means the first £1,000 of rental income is tax-free
• Tenants pay council tax - but landlords are liable when the property is empty or it's an HMO
• Landlord insurance is tax-deductible as an allowable expense
• Landlords pay Stamp Duty Land Tax (SDLT) when buying additional properties - tenants do not
• A 5% SDLT surcharge applies to all additional residential property purchases
• You cannot deduct mortgage interest as an expense anymore - only a 20% tax credit applies (Section 24)
• From April 2027, new property income tax rates of 22%, 42%, and 47% will replace the current rates
• MTD for Income Tax for landlords earning over £50,000 from property

Here's something most landlords don't realise until they get a letter from HMRC: the tax rules for rental income changed significantly back in 2020, and they are changing again in April 2027. If you're still working from the same assumptions you had five years ago, you could be underpaying or overpaying tax on your rental income.

This guide covers everything. What is landlord tax, how much is landlord tax, who pays council tax tenant or landlord, what you can claim, who pays stamp duty land tax, and the upcoming April 2027 changes. Landlord Tax is explained in simple terms.

No jargon. No waffle. Just the stuff that matters.

What is Landlord Tax?

Landlord tax is the informal term for the taxes UK landlords pay on their rental income and property activity. Strictly speaking, it refers to income tax on rental profits, but the full picture includes Stamp Duty Land Tax when buying, Capital Gains Tax when selling, and potentially Council Tax during void periods.

The most important thing to understand: you're taxed on profit, not turnover -take a look at turnover vs. profit here. HMRC taxes what's left after you've deducted your allowable expenses from your total rental income. That distinction matters a lot, so do not skip reading our quick guide above.

Tax on Rental Income

Rental income isn't just the monthly rent your tenant pays. According to HMRC, it includes:

• Rent payments
• Money retained from a deposit (e.g. to cover damage)
• Payments for services such as cleaning of communal areas
• Any additional charges you pass on to tenants

So if you keep £300 of a deposit and charge £100 for cleaning, that's £400 of additional taxable rental income on top of your regular rent.

How Much Tax Do You Pay on Rental Income?

The amount of tax a landlord pays on rental income depends on their total income. Property profit is added to all other income sources and taxed at the applicable band.

Income Tax Rates for Landlords 2025/26

Example: You earn £38,000 from your job and make £9,000 profit from your rental property. Your combined income is £47,000, all of which falls within the basic rate band. You'll pay 20% on the taxable portion above your personal allowance.

Now the important bit: if your rental profit pushes you into the next band, even partially, you'll pay the higher rate on that portion. Many landlords get caught out by this.

What is the New Landlord Tax? The April 2027 Changes

This is the big one that a lot of landlords aren't aware of.

At Budget 2025, the government announced it is introducing separate, higher income tax rates specifically for property income, effective from 6 April 2027. This is confirmed in HMRC's official technical note on the change, published on GOV.UK.

The reasoning: landlords don't pay National Insurance on rental income, so the government is narrowing the gap between employment income and asset income.

New Property Income Tax Rates from April 2027

These rates will apply only to property income, while your employment or self-employment income will still be taxed at the current standard rates. This is a meaningful change, and landlords with larger portfolios or higher total incomes will feel it most.

The buy-to-let mortgage tax credit (currently 20%) will also increase to 22% from April 2027, in line with the new basic rate.

Do I Need to Declare Rental Income to HMRC?

Yes, with limited exceptions. Here's how it works:

• Under £1,000 rental income per year: tax-free under the property allowance. No need to declare.
• £1,001 to £2,500 profit (after expenses): contact HMRC directly; they may collect tax through your PAYE code.
• Over £2,500 profit OR over £10,000 gross rental income (before expenses): you must file a Self Assessment tax return.

Register for Self Assessment by 5 October following the first tax year you received rental income. Miss this, and HMRC may issue penalties. See how to register for self assessment here.

Who Pays Council Tax Landlord or Tenant?

The short answer: the tenant pays council tax in most cases. But there are important exceptions.

Under the council tax hierarchy of liability (as set out by Citizens Advice and supported by UK legislation), the first liable person is the resident - i.e. your tenant. As the property owner, you sit at the bottom of the liability hierarchy, which means you only become liable if no one else is.

Does the Landlord Pay Council Tax?

Landlords are liable for council tax when:

• The property is empty - between tenancies, the landlord is responsible
• It's a House in Multiple Occupation (HMO) - the owner is always the liable person for HMOs, regardless of occupancy
• All tenants are under 18 - the owner becomes liable
• The property is used as accommodation for asylum seekers

Can a Landlord Include Council Tax in the Rent?

Yes, legally a landlord can include council tax in the rent, meaning the tenant pays one combined amount and the landlord passes the council tax payment to the local council on their behalf. This is more common in HMOs and student lets. Just make sure it's clearly stated in the tenancy agreement.

Empty Property Council Tax Premiums

Don't assume a void period means no council tax bill. In fact, councils in England can now charge a significant premium for long-term empty properties, as of April 2025:

Some councils do offer discounts or exemptions for properties undergoing major renovation, but this is entirely at their discretion. Check your local council's policy directly.

What Can a Landlord Claim Against Tax?

This is where you can legally reduce your tax bill. HMRC allows landlords to deduct "allowable expenses" from their rental income before calculating profit. Every pound of allowable expenses saves you money. See more about allowable expenses here.

According to HMRC's own guidance, allowable expenses for residential landlords include:

Is Landlord Insurance Tax Deductible?

Yes, absolutely. Buildings and contents insurance, public liability insurance, and specialist landlord insurance policies are all allowable expenses under HMRC rules. You can deduct the full premium from your rental income before calculating your taxable profit.

This is one of the most commonly missed deductions, particularly by landlords who handle their own tax returns without professional support. Deduct landlord tax before it`s too late, hiring a professional can save you tens of thousands of pounds. Speak to property tax experts Debitam today.

What About Tax on Buy-to-Let Mortgage Interest Relief?

This changed fundamentally in 2020, and it still catches people out.

Before Section 24 of the Finance Act 2015 was phased in, "landlords could deduct 100% of mortgage interest from rental income as an expense." That's no longer the case.

Current rules (and until April 2027): You cannot deduct mortgage interest as an expense. Instead, you receive a 20% tax credit on the lower of:

• Total mortgage interest and finance costs
• Total rental profit
• Total income above the personal allowance

From April 2027: The tax credit increases to 22%, in line with the new property basic rate.

This change hits higher-rate taxpayers hardest. If you're paying 40% tax, a 20% credit on mortgage interest still means a significantly higher effective tax bill than before 2020.

Who Pays Stamp Duty Land Tax Landlord or Tenant?

The landlord (buyer) pays Stamp Duty Land Tax (SDLT) when purchasing a property. Tenants do not pay stamp duty. Use the Stamp Duty Calculator here.

SDLT is payable by whoever is buying the property, so when you purchase a buy-to-let, you're the one footing the stamp duty bill. Tenants renting under an assured shorthold tenancy pay no SDLT (there is a nominal duty on very long-term leases, but this doesn't apply to standard rental agreements).

What is the Stamp Duty Land Tax Surcharge for Landlords?

If you already own at least one property and you're buying an additional residential property, you'll pay an extra 5% surcharge on top of standard Stamp Duty Land Tax rates. This was increased from 3% in October 2024.

There is no relief or exemption from this surcharge specifically for buy-to-let landlords, it applies regardless of how your portfolio is structured.

SDLT Rates for Additional Residential Properties (England & Northern Ireland, from 1 April 2025)

Important: The zero-rate threshold dropped back to £125,000 from 1 April 2025 (it had been temporarily raised to £250,000). Plan accordingly when calculating your purchase costs.

You must pay SDLT and file your return within 14 days of completing the purchase. Your solicitor will usually handle this, but confirm with them.

Scotland uses Land and Buildings Transaction Tax (LBTT), with an Additional Dwelling Supplement of 8% on the total purchase price. Wales uses Land Transaction Tax (LTT) with its own higher rate structure.

National Insurance on Rental Income

Most landlords do not pay National Insurance on rental income. Property income is treated as investment income, not trading income.

However, if being a landlord is your main occupation, meaning you let multiple properties and actively buy properties for rental purposes, HMRC may consider you "gainfully employed" for National Insurance purposes. In that case, from April 2025, the requirement to pay Class 2 NI contributions was removed.

You can still make voluntary Class 2 or Class 3 NI contributions to protect your State Pension entitlement. Worth considering if property is your primary income source.

How to Avoid Paying Too Much Tax on Rental Income (Legally)

This is the question every landlord should be asking, not "how to avoid paying tax on rental income" because that is evasion and its consequences are severe, including imprisonment. How do I make sure I'm not paying more than I legally owe? is what we are about to explain.

Practical and legal approaches include:

1. Claim every allowable expense. Keep receipts for everything: insurance, repairs, letting agent fees, and accountancy costs. Every pound reduces your taxable profit.
2. Use the £1,000 property allowance if your expenses are genuinely low. But if expenses exceed £1,000, which they usually do, claim actual expenses instead.
3. Consider joint ownership. If you're married or in a civil partnership, ownership can be split to ensure rental income is allocated to the lower-earning partner, reducing the overall tax burden. This requires legal advice and must reflect actual ownership.
4. Consider a limited company structure. Companies pay Corporation Tax (currently 25% for profits over £250,000, 19% for smaller companies) and can still deduct mortgage interest in full. This is not right for everyone — seek professional advice before restructuring.
5. Keep records of carried-forward losses. If your allowable expenses exceed rental income in a year, you make a loss. That loss carries forward and reduces your taxable profit in future years.
6. Keep records of carried-forward losses. If your allowable expenses exceed rental income in a year, you make a loss. That loss carries forward and reduces your taxable profit in future years.
7. Prepare for MTD. From April 2026, landlords earning over £50,000 (gross, before expenses) must comply with Making Tax Digital for Income Tax. Quarterly digital submissions replace the annual Self Assessment return. Miss the deadline and penalties follow.

Frequently Asked Questions about Landlord Tax

How much does a landlord pay in tax on rental income?

UK landlords pay income tax on rental profits at 20% (basic rate), 40% (higher rate), or 45% (additional rate) in 2025/26, depending on their total income. From April 2027, property-specific rates of 22%, 42%, and 47% will apply. The first £1,000 of rental income is tax-free under the property allowance.

Who is liable for council tax - the landlord or the tenant?

Under the council tax hierarchy, the resident (tenant) is the liable person. The landlord only becomes liable when the property is empty, when it's an HMO, or when the residents are all under 18. An empty property can attract significant premiums - up to 100% extra council tax after one year of vacancy.

Does the landlord pay council tax?

Not when the property is occupied - the tenant pays. However, during void periods between tenancies, or if the property is an HMO, the landlord is liable. Landlords who pay council tax during void periods can claim this as an allowable expense on their tax return.

Who pays stamp duty land tax - the landlord or the tenant?

The landlord (buyer) pays SDLT when purchasing the property. Tenants renting under a standard tenancy agreement do not pay SDLT. Landlords buying additional properties face a 5% SDLT surcharge above standard rates.

Is landlord insurance tax deductible?

Yes. Buildings and contents insurance, landlord-specific policies, and public liability insurance are all allowable expenses that can be deducted from rental income to reduce taxable profit.

What can I claim against tax as a landlord?

You can claim letting agent fees, landlord insurance, repairs and maintenance, utility bills (if you pay them), council tax during void periods, accountancy fees, ground rent, service charges, cleaning, gardening, and replacement of domestic items. You cannot claim the mortgage capital repayment, property improvements, or the full mortgage interest (only a 20% tax credit applies under Section 24).

What is the new landlord tax from April 2027?

From 6 April 2027, HMRC will apply separate, higher income tax rates to property income: 22% at the basic rate, 42% at the higher rate, and 47% at the additional rate. These are higher than the standard income tax rates, which remain at 20%, 40%, and 45%. The buy-to-let mortgage interest tax credit will also rise from 20% to 22%.

When do landlords have to start using Making Tax Digital?

Landlords with gross property income over £50,000 must comply with Making Tax Digital for Income Tax from 6 April 2026. The threshold drops to £30,000 from April 2027, and is expected to reach £20,000 by April 2028. Quarterly digital submissions replace the annual tax return under MTD.

How do I avoid paying too much tax on rental income?

Legally and practically: claim every allowable expense, keep thorough records, consider joint ownership with a lower-earning partner, explore whether a limited company structure is appropriate for your situation, and carry forward any rental losses. Always consult a professional before making structural changes to your ownership setup.
