Being a commercial property landlord can deliver reliable long-term income and capital growth. But it also brings with it corporation tax liabilities that can reduce profitability if not managed carefully.

One of the most effective tools landlords have at their disposal is capital allowances. This valuable tax relief allows you to offset certain property-related expenditure against your taxable profits, reducing corporation tax and improving cash flow.

At CapexOwl, we specialise in helping commercial landlords identify and claim these allowances, ensuring that no relief is left unclaimed.

Corporation Tax for Commercial Landlords

If you hold property through a UK company, your profits are subject to corporation tax. Since April 2023, the rate is:

  • 25% for profits above £250,000.
  • 19% for profits below £50,000.
  • A tapered rate applies between these thresholds.

Profits include:

  • Rental income (net of allowable expenses like management fees, repairs, and loan interest).
  • Chargeable gains when a property is sold for more than it cost.

Given the scale of investment and income involved in commercial property, tax bills can quickly increase, making capital allowances a crucial planning tool.

What Are Capital Allowances?

Capital allowances provide tax relief for qualifying capital expenditure. Instead of deducting costs through depreciation (which isn’t tax-deductible), allowances let you write off certain property-related costs against taxable profits.

For landlords, the biggest opportunities often come from fixtures and integral features embedded in a property, which can represent a significant portion of the purchase or refurbishment cost.

Which Items Qualify for Relief?

The tax legislation sets out lists of assets (Lists A, B, and C) to assist taxpayers in determining which assets qualify for plant and machinery allowances.  While the structure of a building (walls, floors, roofs) is excluded (but tax relief under the Structures and Buildings Allowances may be available), many items do qualify as plant.

Examples of Qualifying Items for Landlords:

  • Electrical systems (lighting, power, IT cabling).
  • Heating and cooling systems (boilers, air conditioning, ventilation).
  • Hot and cold water systems.
  • Sanitary fittings (toilets, wash basins, showers).
  • Lifts and escalators.
  • Fire alarms and security systems.
  • Kitchen facilities in multi-let offices or retail units.
  • Decorative lighting (in many cases).

If you refurbish, fit out, or even acquire a property, these fixtures are often hidden within invoices and purchase prices. Without specialist review, they can easily be missed.

The Process for Claiming Capital Allowances

The process involves both tax and surveying expertise. At CapexOwl, we follow a structured approach:

1. Initial Review

We assess your property portfolio, acquisitions, or refurbishments to identify potential allowances.

2. Survey and Cost Analysis

Specialists carry out a detailed survey of the property, breaking down costs into qualifying and non-qualifying categories. This includes analysing invoices and construction contracts.

3. Preparation of a Report

A detailed, HMRC-compliant report is prepared, quantifying allowances and categorising them into Annual Investment Allowance (AIA), Full Expensing, 50% First Year Allowances and Writing Down Allowances (WDA), or other reliefs (such as the Structures and Buildings Allowance).

4. Submission Through Tax Return

We work with your accountant to incorporate the allowances into your corporation tax computation. This reduces taxable profits and the company’s corporation tax liability.

5. Ongoing Support

As you acquire, refurbish, or sell properties, we advise on elections to ensure entitlement is preserved and maximised.

Example: Office Landlord

  • A landlord acquires a multi-let office building for £6m.
  • A specialist review identifies £1.2m of qualifying fixtures within the purchase price.
  • At 25% corporation tax, this equates to £300,000 in tax savings.
  • Without a review, these allowances would have been lost.

Why Landlords Often Miss Out

Many landlords fail to claim allowances because:

  • They assume their accountant has made a claim (in reality, specialist input is often required).
  • They don’t realise fixtures are embedded in purchase prices.
  • They overlook the need for elections when buying or selling properties.
  • They lack the detailed breakdowns required by HMRC.

Compliance and HMRC

HMRC fully supports capital allowance claims, provided they are properly evidenced. This means:

  • Accurate identification of qualifying expenditure.
  • Proper apportionment where invoices cover both qualifying and non-qualifying costs.
  • Robust documentation to defend the claim if reviewed.

CapexOwl’s reports are designed to withstand scrutiny, giving landlords confidence that their claims are maximised and compliant.

Final Thoughts

For commercial property landlords, corporation tax is a major expense, but capital allowances provide a powerful way to reduce the burden. By identifying qualifying fixtures and integral features, landlords can release significant cash flow, strengthen returns, and reinvest in their portfolios.

Yet too many landlords miss out, leaving money on the table. With the right specialist support, you can ensure every pound of qualifying expenditure is claimed.

At CapexOwl, we help landlords uncover hidden value in their properties, reduce tax bills, and plan effectively for the future.
