Tax year-end checklist for UK landlords: What you need to do before April 5th

10 min read

The UK tax year-end, falling on April 5th, is a critical deadline for all taxpayers, and landlords are no exception. With the clock ticking, it’s imperative to get your financial affairs in order to avoid penalties and, more importantly, optimise your tax position. Failing to prepare can lead to missed tax relief opportunities, hefty fines, and unnecessary stress. This detailed checklist will assist you in navigating the crucial steps you need to take before the tax year-end to ensure you’re fully compliant and making the most of your rental income.

1. Organise your financial records

The foundation of a smooth tax year-end is having well-organised financial records. As a landlord, you’ll need to provide accurate details of your rental income and expenses when filing your tax return. Here’s what you should gather:

Rental income records

Document all rental income received during the tax year, including rent payments, deposits retained, and any other income related to your property (e.g., service charges or fees).

Mortgage statements and interest details

If you have a buy-to-let mortgage, keep track of your mortgage interest payments. While tax relief on mortgage interest is now restricted to the basic rate (20%), it’s still an important deduction to claim.

Property-related expenses

Maintain records of all expenses related to your rental property, such as:

  • Repairs and maintenance (e.g., fixing a broken boiler or repainting)
  • Insurance premiums (e.g., landlord insurance, buildings insurance)
  • Utility bills (if paid by you as the landlord)
  • Council tax (if paid by you during void periods)

Agent fees and management costs

If you use a letting agent or property management company, keep a record of their fees, as these are tax-deductible.

Receipts for capital improvements

While capital improvements (e.g., adding an extension or replacing a kitchen) aren’t tax-deductible, they can lower your Capital Gains Tax (CGT) when selling the property. Keep these receipts separate from revenue expenses.

Use accounting software like Xero or even a basic spreadsheet to monitor your income and expenses throughout the year. This will save you time and stress when preparing your tax return.

2. Claim all eligible deductions

One of the most effective ways to reduce your tax bill is by claiming all eligible deductions. Here’s a list of common tax-deductible expenses for landlords:

Repairs and maintenance

Costs incurred to maintain the property in a habitable condition, such as fixing leaks, replacing broken windows, or repainting walls, are fully deductible.

Mortgage interest

While tax relief on mortgage interest is now restricted to the basic rate (20%), it’s still an important deduction to claim. Ensure you have accurate records of your interest payments.

Council tax and utility bills

If you pay council tax or utility bills during void periods or as part of a tenancy agreement, these costs are deductible.

Letting agent fees

Fees paid to letting agents for finding tenants or managing the property are tax-deductible.

Legal and professional fees

Costs for legal advice, accountant fees, or other professional services related to your rental business can be claimed.

Insurance premiums

Landlord insurance, buildings insurance, and contents insurance are all deductible expenses.

It’s vital to distinguish between capital expenses and revenue expenses. Revenue expenses, like repairs, are deductible against rental income. Capital expenses, like extensions, are related to the value of the property and are relevant for Capital Gains Tax calculations when you sell the property.

3. Review your capital gains position (If applicable)

If you’ve sold a rental property during the tax year or are planning to sell one, you’ll need to consider capital gains tax (CGT). Here’s what you need to know:

How CGT works

CGT is levied on the profit you make when selling a property that’s not your main residence. The current CGT rates for selling residential properties are 18% for basic-rate taxpayers and 24% for higher-rate taxpayers.

Tax-free allowances

You can benefit from the annual CGT allowance, which is £3,000 for the 2024/25 tax year (dropped from £6,000 previously). This means you won’t pay CGT on the first £3,000 of your gain.

Reducing CGT liability

There are several ways to reduce your CGT liability, including:

  • Private residence relief – If you lived in the property as your own home at any point, you may qualify for partial relief.

4. Make pension contributions or tax-saving investments

The tax year-end is an excellent opportunity to lower your taxable earnings by making pension contributions or other tax-efficient investments. Here’s how:

Pension Contributions

Contributions to a personal pension scheme qualify for tax deductions, which means they can lower your taxable income. For example, if you’re a higher-rate taxpayer, a £10,000 pension contribution could save you £4,000 in tax.

ISAs

Individual Savings Accounts (ISAs) are another tax-efficient option. While contributions to ISAs aren’t tax-deductible, any income or gains earned within the ISA are tax-free.

By making these contributions before April 5th, you can maximise your tax savings for the current tax year.

5. Check your Self Assessment submission requirements

Most landlords are required to submit a Self Assessment tax return to HMRC. Here’s what you need to know:

Deadlines

  • Paper filing deadline: 31 October (for the tax year ending in April of that year)
  • Online filing deadline: 31 January (for the tax year ending in April of the year previous)

Non-resident landlords

If you’re a non-resident landlord, you must declare your UK rental income on a Self Assessment tax return, even if the income is taxed at source.

Let Property Campaign

If you’ve underreported rental income in previous years, consider using HMRC’s Let Property Campaign to disclose any discrepancies and avoid penalties.

Ensure you’re registered for Self Assessment and have all the necessary information ready to file your return on time.

6. Plan for the next year

Once you’ve wrapped up the current tax year, it’s time to plan for the next one. Here are some steps to take:

Keep records updated

Maintain accurate and up-to-date financial records throughout the year. This will make the next tax year-end much smoother.

Work with a professional

Consider working with an accountant or tax advisor specialising in property taxes. An experienced accountant will identify tax-saving opportunities throughout the year and ensure compliance.

Review your portfolio

Take stock of your rental properties and assess their performance. Are there opportunities to increase rental income or reduce expenses?
