Allowable expenses: what you can claim (UK SMEs)

Claiming legitimate expenses reduces your corporation tax bill. Keep records tidy and be consistent.

Common allowable costs

Software, subscriptions, phone, travel for business, marketing, and professional fees.

Grey areas

Meals and clothing are tricky: only claim where they are wholly and exclusively for business.

Receipts and evidence

Use a receipts app and reconcile weekly. Write short descriptions so future‑you remembers what it was.
