What can I claim as a business expense?

You can claim any cost that is wholly and exclusively for your business. Common examples include:

• Office supplies and equipment
• Business travel (excluding the commute to a regular workplace)
• Professional fees such as accountancy costs
• Stock and materials
• Software subscriptions used for work
• Marketing and advertising
• A proportion of your home costs if you work from home
• Training directly related to your current trade

The golden rule is that the expense must be genuinely for business use. If it has a personal element, you can only claim the business proportion.
