Capital Gains Tax on Commercial Property

Capital Gains Tax may arise when an individual, sole trader or partner disposes of commercial property for more than its allowable cost.

Commercial property can include offices, shops, warehouses, industrial premises, workshops and other properties used for business or investment purposes.

The tax position depends on factors including how the property was acquired and used, the amount of the gain, the ownership structure and any available reliefs.

A disposal does not necessarily mean a straightforward sale. Certain transfers, gifts or other transactions can also have Capital Gains Tax implications.

Where a commercial property is owned personally but used by a business, the interaction between the property and the business can make the CGT position more complicated.

Care Accountancy can review your circumstances and help establish whether Capital Gains Tax may apply before you dispose of the property.

A capital gain on commercial property is generally calculated by comparing the disposal proceeds with the allowable cost of acquiring and disposing of the property.

The original purchase price will normally form an important part of the calculation, together with certain qualifying costs associated with acquiring and disposing of the property.

Qualifying improvement expenditure may also be taken into account where the expenditure enhances the property and meets the relevant conditions.

Professional fees and certain transaction costs may also be allowable, depending on their nature and how they relate to the acquisition, improvement or disposal of the property.

Capital losses and applicable CGT reliefs may reduce the amount of gain that is ultimately taxable.

Keeping detailed records of purchase costs, improvements and disposal expenses can therefore be important when calculating your liability.

The amount of Capital Gains Tax payable on a commercial property gain depends on your taxable gain, taxable income, available allowances and any applicable reliefs.

For the 2026/27 tax year, individuals have an Annual Exempt Amount of £3,000. Gains within this allowance are generally not subject to Capital Gains Tax.

For most individual taxpayers, taxable gains are generally subject to CGT at 18% where they fall within the available basic-rate tax band and 24% where they fall within the higher or additional-rate bands.

The position can differ depending on how the commercial property is owned. For example, companies are generally subject to Corporation Tax rather than individual CGT on chargeable gains.

Capital losses and qualifying reliefs can also affect the amount of gain that is ultimately taxed.

Care Accountancy can assess your circumstances and explain how the relevant rates, allowances and reliefs may affect your potential liability.

Business Asset Disposal Relief can reduce the rate of Capital Gains Tax on qualifying disposals of certain business assets, provided the relevant conditions are met.

Commercial property can potentially qualify in certain circumstances, particularly where it has been used by a qualifying business.

The rules depend on factors including how the property has been owned, how it has been used and the relationship between the property and the business.

Additional conditions can apply where an individual has disposed of a business or business assets and where the property has been used by a company or partnership.

Business Asset Disposal Relief is not automatically available simply because a property is commercial or connected with a business.

Care Accountancy can review the ownership and use of your commercial property to determine whether the conditions for the relief may be satisfied.

Business Asset Rollover Relief can potentially allow a qualifying capital gain to be deferred when a business disposes of certain qualifying assets and reinvests the proceeds in other qualifying business assets.

Commercial property can be relevant where the property qualifies as a business asset and the other conditions for the relief are satisfied.

The timing of the disposal and acquisition of the replacement asset is important, as specific time limits and conditions apply.

Rollover Relief generally defers the gain rather than permanently eliminating the Capital Gains Tax liability.

The relief can therefore be particularly relevant when a business is selling one commercial property and reinvesting in another qualifying business asset.

Care Accountancy can help assess whether Rollover Relief could apply and explain the potential tax implications of reinvesting the proceeds.

The reporting requirements for a commercial property disposal depend on who owns the property and the nature of the disposal.

Individuals may need to report a taxable gain through Self Assessment, while different rules can apply where the property is owned by a company or other structure.

The special 60-day reporting and payment requirement applies to qualifying disposals of UK residential property, so it should not automatically be applied to commercial property disposals.

It is important to establish the correct reporting route and deadline before disposing of a commercial property, particularly where the transaction forms part of a wider business sale or restructuring.

Late reporting or payment can result in penalties and interest where a liability is due.

Care Accountancy can help calculate the gain, identify relevant reliefs and assist with the appropriate reporting requirements.
