This guide has been produced for information purposes only. As a buy to let mortgage broker, we're not able to offer tax advice.

Buy to lets can be extremely lucrative so they attract a lot of entrepreneurial thinkers. They also intimidate masses of potential landlords because they’re taxed in a very specific way.

UK landlord tax comes in different forms: Stamp Duty Land TaxCapital Gains Tax and Income Tax. These are the main 3. But you don’t pay them all at once. Stamp Duty you pay on the initial property purchase and you’re charged Capital Gains Tax when you sell an investment property. Income Tax is the only tax you’ll pay on an ongoing basis for an occupied buy to let property as a private landlord.

If you get a buy to let via a limited company in the UK, you'll pay Corporation Tax on the rental income instead. You can find more information on this below.

You can also compare limited company buy to let mortgage rates with our free best buys tool if you'd like to know more this kind of setup.

Note: the Financial Conduct Authority does not regulate some forms of buy to let mortgages.



Why Do You Pay Tax on Rental Income?

By becoming a landlord, you’re setting up an ongoing financial source of income – the rental income you receive from tenants. You pay tax on rental income like any other monthly earnings.


What Counts as Rental Income?

Rental income is classed as any money you receive from tenants for:

  • Rent
  • Furniture usage
  • Fees for services such as cleaning or gardening
  • Regular maintenance
  • Heating
  • Repairs
  • Hot water
  • Lease bonuses or other non-refundable deposits
  • Any amounts received from tenant forfeits or deposit retentions

How Is Rental Income Taxed UK?

You pay Income Tax on rental income. This has many names in the UK: landlord income tax, property income tax, buy to let Income Tax, etc. But these all refer to the Income Tax you pay on rental income.

You’re taxed on your net rental income - i.e. the profit you make. This is calculated by adding together all the rental income you receive from various properties and then subtracting any rental Income Tax allowances, relief or allowable expenses (total rental income minus property allowance or allowable expenses).

See Buy to Let Allowable Expenses below for more information on those landlord-only tax deductions.


How Much Tax Do You Pay on Rental Income UK?

Your Income Tax band determines how much tax you’ll pay on rental income in a given year. Since rental income is added to your total taxable income, it may push you into a higher tax band.

Income Tax Rates and Thresholds (2024 - 2026)

The tax rates for rental income are the same as personal income tax rates:

Income Tax Band

Taxable Income 2024 – 2025

Income Tax Rate 2024 - 2025

Taxable Income 2025 - 2026

Here’s some important information about paying tax on rental income:

  • If your total income (salary + rental income + other income sources) is less than £12,570, you pay no tax on rental income
  • If your total income is above £100,000, your personal allowance is reduced by £1 for every £2 over this amount
  • If your total income exceeds £125,140, you do not get a personal allowance at all, meaning all income is taxable

Note that from 2028 - 2029, the Income Tax thresholds will likely be uprated in line with inflation. 

Example 

  • You earn a salary of £40,000 
  • You also receive £20,000 in rental income 
  • You deduct £5,000 in expenses from your rental income to reveal your net rental income of £15,000 
  • These are your only sources of income 
  • You add together your salary and net rental income to determine your total taxable income: £40,000 + £15,000 = £55,000 
  • You fall within the higher rate tax band 

You’ll pay: 

  • 0% on the first £12,570 = £0 
  • 20% on the amount above £12,570 and up to £50,270 (£37,700 total) = £7,540 
  • 40% on the remaining £4,730 above £50,270 = £1,892 
  • Total Income Tax, including tax on rental income = £9,432 

How Does Rental Income Affect Your Tax Band UK?

Rental income is not taxed separately - it is added to your other sources of income, which determines your overall tax rate.

Example scenarios:

  • Income below £12,570 = you pay 0% tax on rental income
  • Income between £12,570 and £50,270 = you pay 20% tax on rental income
  • Income between £50,270 and £125,139 = you pay 40% tax on rental income
  • Income from £125,140 = you pay 45% tax on rental income

Types of Property Ownership and Impact on Tax

The main types of property ownership that can affect the Income Tax you pay include the following:

  • Sole ownership - if you own the rental property by yourself, you’ll pay Income Tax on the whole income from that property
  • Jointly-owned property - if you own a rental property with other people, you’ll pay Income Tax on the property’s income relative to your share in the property. If you jointly own some properties and solely own other properties, the income is counted as one business for tax purposes 
  • Property jointly-owned with a spouse or civil partner - if you own a property with your civil partner or spouse, you will usually be taxed as if you own equal shares of the property. If you own unequal shares, you will need to demonstrate and provide proof of this to HMRC in order to pay the correct tax 
  • Owning property through a company - if you own property through a limited company, you’ll be liable for Corporation Tax on the profits not Income Tax

Buy to Let Tax Allowable Expenses

Landlords are taxed on their net rental income - i.e. the profit left over when you subtract your property allowance or allowable expenses from the total amount you receive in rent. HMRC have strict tax rules on the income from rental property, so there are limits as to what you can claim as a buy to let allowable expense.

Property Allowance

The first £1,000 of rental income you receive each tax year is tax-free, known as the Property Allowance. This means that landlords earning £1,000 or less in gross rental income do not need to report it to HMRC or calculate expenses, as they receive full tax relief. 

If your rental income exceeds £1,000, you must declare it and choose between: 

  • Claiming the £1,000 Property Allowance, or 
  • Deducting actual allowable expenses from your rental income 

You cannot claim both in the same tax year. 

Landlords who choose the Property Allowance benefit most when their deductible expenses are less than £1,000, as they can claim a larger tax-free portion of their rental income. 

Deductible Expenses on Rental Income

You do not pay tax on allowable rental expenses, but they must meet certain criteria. Expenses can only be deducted if they are exclusively related to renting out the property and paid by the landlord, not the tenant. 

Common deductible expenses include letting agent fees, maintenance and repairs (not improvements), Council Tax, and landlord insurance.  

Landlords can no longer deduct mortgage interest from their taxable profit however they do receive a tax credit equal to 20% of their mortgage interest payments, which is subtracted from their final tax bill. 

What Qualifies as a Deductible Expense for Rental Income?

  •  General maintenance and necessary repairs but not improvements

  •  Replacement of some domestic items

  •  Letting agent fees and management fees

  •  Accountant’s fees

  •  Insurance - e.g. landlords’ policies for buildings, contents and public liability

  •  Water rates, Council Tax, gas and electricity

  •  Legal fees for lets of a year or less

  •  Legal fees for renewing a lease for less than 50 years

  •  Direct costs - e.g. business phone calls, stationery and advertisements

  •  Vehicle running costs for your rental business

What Doesn’t Qualify as a Deductible Expense for Rental Income?

  • Mortgage interest - learn about the new tax credit system below

  • Your full mortgage payment – see below for more information

  • Home improvements - e.g. replacing carpet with wooden flooring

  • Calls not related to your property rental business

  • Clothing

  • Personal expenses


Tax Relief on Rental Income

Do I Pay Tax on Rental Income if I Have a Mortgage?

Yes you still pay tax on rental income if you have a buy to let mortgage.

However, you receive Income Tax relief in the form of a tax credit, which reduces the tax payable on your rental income. The relief is equal to 20% of your mortgage interest payments. 

This system replaced the previous mortgage interest deduction, which allowed landlords to offset their full mortgage interest against rental income before calculating their tax.

For more landlord tax advice see our Buy to Let Tax Changes guide.

Mortgage Interest Relief Tax Credits and How They Work

  • Your rental income is included in your total taxable income
  • Previously, landlords could deduct mortgage interest from their rental income before calculating their taxable profit. This reduced taxable income, lowered the amount of tax owed and could even keep landlords in a lower tax bracket
  • Now, instead of deducting mortgage interest from rental income:
    • You calculate your taxable rental profit without deducting mortgage interest
    • You pay Income Tax on the full rental profit at your applicable Income Tax rate (20%, 40%, or 45%)
    • You receive a 20% tax credit on your mortgage interest costs, which is applied against your final Income Tax bill rather than reducing your taxable rental income

Let's break this down:

  1. You are a higher rate taxpayer (40% tax rate) 
  2. Your rental income is £30,000 per year
  3. Your mortgage interest payments total £10,000 annually
  4. Your allowable expenses (e.g. maintenance, insurance, etc.) are £5,000
  5. Rental Income (£30,000) minus Other Expenses (£5,000) = £25,000 taxable profit
  6. Note that mortgage interest (£10,000) is not deducted at this stage
  7. Your Income Tax owed is 40% of £25,000 = £10,000
  8. Your mortgage interest tax credit is 20% of £10,000 = £2,000
  9. Your tax credit (£2,000) is deducted from your tax liability (£10,000) = £8,000
  10. £8,000 is your final Income Tax bill

What Happens with Income from Multiple Properties?

If you own multiple rental properties, the income from all properties is typically combined to determine your total rental income. Expenses from one property can often be deducted from the income of another, which can help in reducing your taxable income. Here are key points:

  • Keep detailed records for each property
  • Aggregate income and expenses to calculate the total taxable amount
  • Use the total net profit or loss across all properties in your tax calculations

Do I Have to Pay UK Tax on Income from a Property Overseas?

Tax for overseas property rentals is largely handled in the same way as UK property rentals. If you live in the UK and are domiciled in the UK, it’s likely you’ll have to pay Income Tax on your income from overseas properties. If you’re not a UK resident, you won’t have to pay UK Income Tax on this rental income. This includes if you’re in the UK but your permanent home or domicile is overseas. 

Depending on your circumstances, you might have to pay tax to the country from which you gain the income as well as pay UK Income Tax. You can look into Foreign Tax Credit Relief to reduce how much tax you have to pay. If you have rental properties in the UK as well as overseas, it is highly advisable to get professional advice from a tax adviser or accountant.


Losses: Handling Rental Income Tax Losses

If your allowable expenses exceed your rental income, you will have made an Income Tax loss. This is common in the first year of renting out a property due to upfront costs such as refurbishments, letting agent fees and other expenses. 

  • Rental losses cannot be offset against salary, dividends, or other income 
  • Losses can be carried forward to reduce taxable rental profits in future years 
  • If you own multiple rental properties, a loss from one can offset profits from another within the same tax year

How Do You Pay the Tax Due on Rental Income?

The process of paying tax on buy to let property income depends on the amount of rental income you receive. 

If you: 

  • Earn less than £1,000 a year in rental income - you don’t have to report it to HMRC unless you choose to claim expenses instead of the £1,000 property allowance 
  • Earn between £1,000 and £2,500 a year in rental income - you should contact HMRC to check whether you need to complete a Self-Assessment tax return or if the tax can be collected via your tax code 
  • Earn between £2,500 and £9,999 after allowable expenses, or over £10,000 before allowable expenses - you must register with HMRC and file a Self-Assessment tax return to report your rental income 

About Landlord Tax Returns

HMRC use self-assessment tax returns to collect Income Tax from people who receive income from sources other than their salary - e.g. income from rent. Therefore, landlords pay the tax due on rental income by completing a self-assessment tax return.

You fill out a self-assessment tax return every tax year, which runs from 6th April of the current year to 5th April of the following year. HMRC then use these figures to determine how much tax you need to pay. You must keep the receipts from any work you’ve had done on your property when you complete a tax return for a buy to let to claim any expenses.

There are 2 ways landlords can complete self-assessment: 

  • You fill out the tax return yourself
  • You employ an accountant to self-assess on your behalf

Why Do It Yourself?

Many landlords choose to complete their own tax return as it eliminates the cost of an accountant. Self-assessment isn’t a way to avoid landlord taxes. You need to be honest and thorough if you choose to complete your own self-assessment.

Filing a self-assessment tax return as a landlord involves several steps:

  • Register for self-assessment with the tax authorities
  • Keep accurate records of all rental income and allowable expenses
  • Complete the relevant sections of the self-assessment tax return form
  • Report any other sources of income as required
  • File the return and pay any tax due by the deadlines set by the tax authorities
  • Consider using online filing options to simplify the process

Why Use an Accountant?

Not everyone knows how to file rental income on their taxes. By using an accountant, you’re minimising the risk that you’ll make an avoidable mistake. Your accountant will know how rental income is taxed, what you can claim and which receipts you need to keep. As a general rule, we suggest using an accountant with property taxation experience. They can guide you if there are some decisions to make regarding whether or not to own property in your personal name through a limited company.

How to Calculate Rental Income Tax UK

To determine how much tax you owe on rental income, follow these steps:

1. Calculate Your Total Income

  • Add up all employment income (including bonuses, overtime, etc.)
  • Add any business income or other taxable earnings
  • Add your gross rental income (before expenses or deductions)

2. Deduct Allowable Expenses or Property Allowance

  • Either deduct the £1,000 property allowance OR
  • Deduct actual allowable expenses (e.g. maintenance costs, letting agent fees, etc.)

3. Determine Your Net Rental Income

  • Net Rental Income = Total Rental Income - Allowable Expenses or Property Allowance

4. Find Your Marginal Tax Band

  • Add net rental income to your total other taxable income
  • Check which Income Tax band your total income falls into

5. Apply the Correct Tax Rate

  • Tax is charged only on the portion of income within each tax band (not all at one rate)

6. Apply the Tax Credit

  • 20% of what you pay in mortgage interest is then deducted from your overal Income Tax bill

7. You're Left with Your Final Rental Income Tax Bill

  • You're done!

Record Keeping Tips for Rental Income

It’s important to keep accurate records of your income and allowable rental expenses from rental properties. These should be split into your income from different categories, such as overseas properties, UK properties, fully-furnished lettings and unfurnished/part-furnished lettings.

You should make sure you have all relevant evidence of the property - such as rent books, receipts, invoices, bank statements and mileage logs. If you don’t have this evidence, you could be charged a fine when it comes time to pay tax on rental income.


How to Avoid Paying Tax on Rental Income

Looking for tips on how to avoid landlord taxes isn’t the best idea, as the suggestions you’ll find are usually unreliable and more risk than they’re worth. Instead, make yourself aware of the allowances that suit your situation and discuss tax-efficiency with your accountant. You may learn how to pay less in tax on rental income than you first thought.

The Best Way to Track Allowable Expenses and Reduce Tax on Rental Income

Tracking allowable expenses is crucial for reducing your taxable rental income. Best practices include:

  • Maintain a dedicated bank account for all rental income and expenses
  • Use digital tools or accounting software to record and categorize expenses
  • Keep receipts and documentation for all allowable expenses - such as repairs, maintenance, property management fees, insurance, etc.
  • Regularly update your records to avoid last minute tax filing stress
  • Consult with a tax professional to ensure all potential deductions are identified

Limited Company Buy to Lets Can Be Tax-Efficient

Some landlords find it more tax-efficient to purchase a buy to let property through a limited company, as the taxation of rental income differs from that of personally owned properties. 

You do not pay personal Income Tax on rental property owned through a limited company. Instead, the company pays Corporation Tax on its profits. HMRC does not consider your personal income when determining the Corporation Tax rate, as it applies at the company level. 

Corporation Tax rates for 2024/25: 

  • 19% for profits up to £50,000 
  • 25% for profits over £250,000 
  • Marginal relief applies for profits between £50,000 and £250,000, meaning the effective rate is between 19% and 25%, depending on profit levels 

This structure can sometimes be more tax-efficient, which is why many landlords consider using a limited company. 

Additionally, landlords operating through a limited company may have greater flexibility in claiming allowable expenses, as the property is considered a business asset rather than a personal investment.

Additional Landlord Tax Considerations

Although you only pay Income Tax on the house rent received each month, there are other taxes you may have to pay at some point during your landlordship. It all depends on your circumstances.

Landlord Taxes When Purchasing a Property

A tax landlords must pay on purchase is Stamp Duty Land Tax (SDLT).

If you buy a second home, holiday let, or buy to let property, you must pay the standard SDLT rates plus an additional 5% surcharge on properties worth more than £40,000. This surcharge applies because the property is not your main residence.

From 1 April 2025, the thresholds will change, and the surcharge will still apply on top of standard rates.

Different property tax rules apply in Scotland (LBTT) and Wales (LTT).

You can learn more in our Second Home Stamp Duty guide or use our Buy to Let Stamp Duty Calculator to work out how much SDLT you’ll pay on rental property.

Council Tax

As a landlord, you won’t pay the Council Tax on your buy-to-let properties unless they’re unoccupied. Council Tax is usually the responsibility of the tenant, but you may be liable if they leave. You can claim buy-to-let Council Tax as an expense when you complete your self-assessment tax return.

Capital Gains Tax

When you sell a rental property, you may be liable to pay Capital Gains Tax (CGT) on the profit.

Key points to remember include:

  • Calculate the gain by subtracting the property's purchase price from the sale price. You then take this figure and deduct any allowable expenses (such as agency fees and property improvements) and the CGT allowance. This give you the amount of capital gain you will pay tax on
  • Check if you qualify for any CGT reliefs or exemptions
  • Report the sale on your tax return and pay the due tax within the specified timeframe
  • Keep all documentation related to the purchase, improvement, and sale of the property to substantiate your calculations
