What Is a Landlord Tax Return?
The landlord tax return is the process through which landlords file self-assessment reports about their rental income and expenses to HMRC. This report is submitted to HMRC through the main SA100 form and the supplementary SA105 pages for property income. In case you file online, HMRC will calculate the tax. For paper filing you or an accountant will have to work out the tax. The landlord has to file that tax within the time limit. Failure to do so may result in penalties.
This process ensures that:
- All income from your rental properties is declared.
- Deduct expenses to lessen your tax.
- You pay the right amount of tax.
- Make sure that your tax returns are in compliance with HMRC regulations.
Landlords have to report their income and expenses manually. As part of this process, you complete a landlord self-assessment tax return.

Who Needs to File a Landlord Self-Assessment Tax Return?
You are eligible to file landlord self-assessment tax return if your rental income exceeds £1,000. The first £1,000 of your rental income is tax-free. This is the tax-free allowance. If your income is anywhere between £1,000 to £2,500, you should report to HMRC. If it’s more than £2,500, you must report landlord tax return on a self-assessment tax return after allowable expenses and £10,000 before allowable expenses.
Other than basic limits, you are eligible for a landlord taxation return if any of the following conditions are met:
- You own furnished holiday lettings (FHL) or overseas property.
- You jointly own a property and receive rent from it.
- The total income from all your rental sources exceeds the personal allowance.
- You have sold a rental asset.
- HMRC has issued a notice to file a return.
Even if your income is below the allowance limit, it is good to file a return to claim tax relief.
How to File For Landlord Tax Return: A Step-by-Step Guide
Now we will go through each step of the process of filling out the landlord self-assessment tax return. Before laying out the process, we should understand what a landlord tax return is and what is the eligibility criteria for it.
Step 1: Check If You Need to File
Before even starting to file, you must make sure that you are eligible to file for the tax return. The conditions for filing have already been provided. Work out your income and expenses to see if it is above the taxation threshold. If your income from rental property is above £1,000, then you may need to register for self-assessment.
Step 2: Register for Self-Assessment
Before filing for your first landlord tax return, you need to register with HMRC. Registration can be done online or via form SA1. For landlords, you have to fill form SA-105. This is a document that discloses your earnings from rent. If you are filling online you may not have to fill SA-105.
Here is how you register online:
- Visit the HMRC online registration portal.
- Complete form SA1 (if you already have a tax record), or the self‑employed registration if applicable.
- You need to enter your National Insurance number, address, and letting start date.
- Receive your Unique Taxpayer Reference (UTR).
This UTR must be kept safe. It is needed every time you complete an HMRC landlord tax return.
Important Deadlines
Here are some important deadlines. Missing these deadlines may result in penalties and interest.
Step 3: Gather Your Records
The most important thing in maintaining a smooth tax return is keeping clean records. Records include:
- Rental income received.
- Allowable expenses paid.
- Mortgage interest statements.
- Receipts for repairs and maintenance.
- Tenancy agreements and deposits.
HMRC requires that you keep these records for at least five years after the 31 January filing deadline for the relevant tax year.
Step 4: Find Allowable Expenses
Allowable expenses are the expenses you can deduct from your income before calculating your taxable profit.
Quick rule: repairs and maintenance are usually allowable, but improvements (upgrades that add value) are not treated the same way.
There is a wide range of costs you can deduct before calculating tax.
Common Allowable Expenses:
- Letting agent fees.
- Property insurance.
- Maintenance and repairs (not improvements).
- Utility bills (if the landlord pays).
- Council tax (if landlord is responsible).
- Legal and accounting fees.
- Advertising for tenants.
- Inventory and tenancy setup costs.
All these expenses must be deducted from your net income before calculating HMRC landlord tax return.
Reminder:
Mortgage interest is no longer deducted from rental income. You receive a 20% tax credit based on your finance costs. This change can change your tax position, at this rate, even some basic taxpayers can be pushed into a higher-rate taxpayer category.
The impact is strongest on higher-rate taxpayers. As the 20% credit increases their tax liability.
Step 5: Calculate Tax on Your Rental Income
Your taxable profit is calculated as:
Net rental income = Rental income – Allowable expenses
For instance,
If your rental income = £24,000 per year
Your allowable expenses = £6,000
Your net rental income = £24,000-£6,000 = £18,000.
This is the figure that will be taxed through your landlord self-assessment tax return.
If you own multiple properties, you must combine all rental income and expenses to calculate total profit. HMRC treats your rental business as a single entity even if you have many properties.
Step 6: Complete Your Landlord Tax Return (SA100 + SA105)
Use form SA100, with supplementary pages SA105 for property income.
You’ll need to:
- Enter rental income.
- Deduct allowable expenses.
- Include mortgage interest as a tax credit.
- Report other property income (holiday lets, overseas rentals).
- Online submission is recommended. It’s quicker, reduces errors, and gives instant confirmation.
Step 7: Pay the Tax
After submitting your landlord self-assessment tax return, HMRC calculates your tax liability. Payment options include:
- Bank transfer.
- Direct debit.
- Debit/credit card.
If your tax bill exceeds £1,000, HMRC may require payments on account, which are advance payments toward next year’s tax. These are due:
- 31 January – First payment.
- 31 July – Second payment.
If you cannot pay in full, you can request a payment plan. HMRC allows for that.
Step 8: Plan Ahead for Next Year
Effective tax planning allows landlords to:
- Keep accurate records.
- Utilise allowable expenses.
- Plan for Capital Gains Tax on future property sales.
- Consider alternative ownership structures, such as limited companies, for tax efficiency.
Keeping on top of these steps ensures your HMRC landlord tax return is straightforward in subsequent years.

Step 9: If You Sold a Rental Asset Check Capital Gains Tax
Capital Gains Tax or CGT is applied when you sell a rental asset. It is the tax on gains made from the proceeds. It is calculated as:
Gains = Sales price – purchase price – costs
Note: “Costs” can include certain buying/selling fees and some improvement costs, and special rules/reliefs can apply. Always check what HMRC treats as allowable for your situation.
The amount of tax depends on a number of factors such as the gains made, the type of asset and whether you are a basic taxpayer or a higher taxpayer.
Capital gains tax does not apply if the asset in question was your main home. There are also letting reliefs in limited cases.
Step 10: Check if Digital Tax Returns for Landlords Apply
HMRC requires landlords with income above £50,000 to use digital records and submit updates quarterly. This has been in effect since 6 April 2026. By 6 April 2027, the threshold will lower to £30,000. Benefits of digital tax returns for landlords include:
- Reduced risk of errors
- Easier end-of-year filing
- Less paperwork and faster updates
- Investing in compatible software early can save significant time

Even with proper guide taxes can be tricky. There are some pitfalls you need to be aware of as a landlord, when filling landlord tax returns.
