Accounting & tax glossary

Capital expenditure

Capital expenditure is spending on acquiring or improving assets that provide benefits beyond the current accounting period.

Why it matters

Distinguishing capital spending from everyday running costs helps accounts represent both performance and the assets used by the business. The decision depends on what was bought and why, not just the amount on the invoice. Repairs, replacements and improvements can need careful assessment, particularly for property and equipment. Tax rules then need a separate review.

A practical example

A workshop buys a new diagnostic machine rather than paying for its annual servicing. The purchase may create a fixed asset in the accounts, while routine servicing is normally considered as a running cost. Funding the machine through instalments adds a further distinction between the asset, borrowing and cash payments.

A common misunderstanding

Paying cash does not automatically make a purchase an expense of that month. Equally, a large invoice is not necessarily capital. Keep an explanation of the work and obtain a review of borderline items before assuming the accounts and tax treatment are identical.
