Every legitimate business cost you fail to record is profit you pay tax on unnecessarily. Freelancers and sole traders are especially prone to this because costs are small, scattered and often paid from a personal card. This is general information, not tax advice. Rules differ by country and by circumstance, so check what applies to you.
Costs that are easy to forget
- Software and subscriptions: design tools, cloud storage, accounting software, domain names and website hosting.
- Professional fees: your accountant, legal advice, insurance and professional memberships.
- Bank and payment fees: account charges, card processing fees and transfer fees, often lost in the statement.
- Equipment: laptops, phones, monitors, desks and chairs used for work. Larger items may be treated differently from day-to-day costs.
- Training and books: courses and materials that keep your skills current for the work you do.
- Travel and parking: journeys made for business, such as meeting a client, but usually not commuting to a regular place of work.
- Phone and internet: the business-use portion of bills you share with your private use.
- Home office: in many countries you can claim a share of home costs or a flat rate when you work from home. Check the method your tax authority allows.
- Advertising and marketing: ads, printing, business cards and sponsorship.
Why costs go missing
The usual causes are paying business costs from a personal account, losing paper receipts and leaving statements unreconciled for months. By the time you sit down at year end, nobody remembers which subscription was for work.
Habits that fix it
- Separate business and personal money. A dedicated business account makes every transaction easy to classify.
- Capture receipts at the time. Photograph them or attach the supplier’s PDF to the bill straight away. See Attach documents and see a record’s history.
- Import your bank statement every month and reconcile it, so nothing slips by. Bank rules categorise repeating costs for you.
- Review your expenses report quarterly and look for categories that seem too low.
- Keep records for the period your tax authority requires. It is often several years.
A note on what you cannot claim
Costs must normally be incurred for the business. Personal spending, fines and penalties, and entertaining clients are commonly restricted or disallowed. When in doubt, record the cost and ask your accountant how to treat it, rather than leaving it out.
Good records are the foundation of every claim. Start with a clean set of books, and the rest becomes much easier.
