Everyday running costs

Stock and materials, software and subscriptions, phone and broadband (business portion), bank charges and business insurance are all allowable.

Working from home

Use HMRC’s simplified flat rate based on hours worked, or apportion actual costs by floor area and time. Most sole traders find the flat rate simplest and safest.

Travel and vehicles

Claim the Approved Mileage Allowance for business journeys in your own car, plus public transport, parking and accommodation on genuine business trips. Ordinary commuting doesn’t count.

What you can’t claim

Personal costs, everyday clothing (even if only worn for work), client entertaining and fines are not allowable. When in doubt, the test is ‘wholly and exclusively’ for the business.
