How to Calculate Landlord Income Tax

Landlord Income Tax Process

The process flow to the right defines the factors affecting your income tax calculation as a landlord. When calculating your income tax, it is easier to look at the process in reverse and understand how each of the elements are calculated. A common mistake that landlords make when submitting their tax return is to combine their own expenses and the expenses generated from the properties. This is incorrect, the correct tax process is to separate those expenses (treat the properties as a separate income revenue).

Net income = Gross Taxable Income - Income Tax Payable and National Insurance

Gross Taxable income = Gross Income - Personal Expenses

Gross Income = Profit from Properties + Personal Earnings

Profit from Properties = Income from Properties - Expenses from Properties

Legitimate Property Expenses for Landlords

As with the majority of taxes, it is your responsibility to ensure that you deduct any legitimate costs generated as part of income. If you don't deduct legitimate expenses, you will pay extra tax. Not claiming expenses is basically burning your hard earned cash.

The following expenses are legitimate expenses which occur as part of owning, maintaining and leasing/renting a property:

Accountant expenses

Only accounting expenses incurred in preparing rental business accounts, not accounting expenses incurred for preparing personal tax returns

Legal and Professional fees

Any legal fees incurred in the day to day management of your rental property. Including:

  • The cost of preparing leases and inventories
  • Collecting rent
  • Preparing your tax return for the property (properties)
  • Letting agent charges

Advertising costs of attracting new tenants

Including agency advertising costs, using a website like Rightmove, newspapers and so forth.

Charge for inventories

Most rental agencies will prepare an inventory for you for a fee which is a legitimate landlord expense.


Corrective and periodic (e.g. having carpets deep cleaned).

Costs of rent collection

Typically encompassed in Rental Agency fees though you may incur vehicle and fuel expenses if collecting in person (be careful, check with your accountant for advice pertinent to your particular situation).

Council Tax while the property is vacant and available for letting.

Typically, you will be afforded up to 6 months Council tax free though this has started to vary between regions with new legislation potentially ending this expense.

Note that a Council Tax exemption is typically facilitated through your local council and not reclaimed as an expense during annual income calculation.


Corrective and periodic garden maintenance.
