Understanding Expenses If You're Self-Employed

The core rule is that an expense must be "wholly and exclusively" for business purposes. This includes things like office costs, travel, and stock. If you use something for both business and personal reasons (like a mobile phone), you can usually only claim a proportion of the cost.
