Capital Expenditure (CapEx)

Capital expenditure - often shortened to CapEx - is the money a business spends to purchase, upgrade, or improve assets that will deliver value beyond the current financial year. Unlike day-to-day operating costs, CapEx creates an asset on your balance sheet rather than an immediate expense on your profit and loss statement. For small to medium-sized businesses, understanding the distinction between CapEx and operating expenditure affects how you budget for equipment, how you report profit, and how you manage your tax position.

How CapEx Differs from Operating Expenditure

When a business buys a commercial van, installs specialist plant, purchases workshop tools, or fits out a second premises, those are typically capital expenditures. The asset appears on the balance sheet at its purchase cost and is gradually reduced through depreciation over its useful life. Each year, a portion of the asset's value moves from the balance sheet to the profit and loss statement as a depreciation charge.

Operating expenditure covers the recurring costs of running the business day to day - wages, rent, insurance, software subscriptions, and vehicle fuel. These are expensed in full in the period they occur and appear immediately on the profit and loss statement.

A practical illustration: a £15,000 company van is CapEx; the monthly fuel, insurance, and servicing costs are OpEx. A piece of specialist scaffolding bought outright is CapEx; the weekly hire of additional scaffolding from an external supplier is OpEx.

It also helps to know that CapEx has two subtypes. Maintenance CapEx covers spending to keep existing assets operational - replacing a worn-out engine component in a machine, for example. Growth CapEx covers new investments that expand what the business can do, such as buying additional plant or acquiring a second premises.

How CapEx Is Recorded and Its Tax Implications

Because CapEx creates a long-term asset, it is not expensed in full on the profit and loss statement in year one. The asset is depreciated - a portion of its cost is charged each year over its useful life. A £30,000 piece of production equipment depreciated over five years reduces profit by £6,000 per year rather than £30,000 in the year of purchase.

For tax purposes, HMRC does not use accounting depreciation. Instead, businesses claim capital allowances on qualifying asset purchases. The Annual Investment Allowance allows most businesses to deduct the full purchase cost in the year they buy an asset, which can significantly reduce the tax bill in that year.

Getting the classification right matters. If a capital purchase is incorrectly recorded as an operating expense, your reported profit for that period will be understated and your tax position inaccurate.
