What Actually Counts as a Business Expense When You Are Self-Employed?
The simple test behind most tax rules, the costs people forget, and why logging them is money in your pocket.
"Can I claim this?" is one of the most Googled questions in freelancing, usually asked while hovering over a receipt for a coffee, a laptop, or a train ticket. The honest answer is that it depends on your country's rules, but there is a simple principle underneath most of them that will get you most of the way.
A quick warning before we start. Tax law is specific to where you live and it changes, so treat this as a way to think about expenses, not as a ruling on your particular situation. For the edge cases, ask an accountant.
The basic test
Across most tax systems, a cost is claimable if it is genuinely for the business. Different countries phrase it differently, things like "wholly and exclusively for the business" or "ordinary and necessary," but the spirit is the same. Would you have spent this money if you were not running this business? If the answer is no, you can probably claim it. If it is something you would have bought anyway, you probably cannot.
The grey area is anything you use for both work and life. A phone you use for clients and for texting friends, a room that is an office on weekdays and a spare bedroom at weekends. In those cases you usually claim the business portion, not the whole thing. Be reasonable and be able to explain your split, and you will be fine.
The costs people forget
Most freelancers remember the big obvious ones, the laptop and the software. The money tends to leak through the small recurring stuff that never feels like a "business expense" in the moment.
Things like your design or accounting subscriptions, the fees the payment platforms quietly take from every sale, professional memberships, a course or book that genuinely relates to your work, the business slice of your phone and internet, bank charges on a business account, and travel to see clients. None of these feel dramatic, but they add up to real money over a year, and every one you record lowers what you are taxed on.
Why this is worth the bother
You are taxed on profit, which is your income minus your allowable costs. So an expense you forget to claim is not just untidy bookkeeping. It is money you pay tax on despite never really keeping it. Record a 40 a month subscription all year and you have correctly removed nearly 500 from the income you get taxed on. Forget it, and you hand a slice of that 500 to the tax office for no reason.
If you want to see how your expenses change your actual tax, our free calculator lets you enter your income and your costs and shows your profit and what to set aside. Watch the set-aside figure drop as you add expenses, and you will never skip logging one again.
Keep the receipts, properly
A claim you cannot back up is a claim you can lose if anyone ever asks. So keep proof, and keep it in a way you will still understand next year.
The painless method is to capture each receipt the moment you have it, rather than promising to file it later. A photo is usually fine. What matters is that you can match each expense to a date, an amount and a reason. Most tax authorities expect you to hang on to records for several years, so a tidy folder or a spreadsheet beats a drawer full of fading till slips.
This is exactly what a simple tracker is for. Ours gives every expense a category and adds it all up against your income automatically, so your claimable total is sitting there ready at tax time instead of scattered across your inbox. It lives in the same spreadsheet as your income, invoices and tax estimate. You can see it at Roots & Receipts.
Get into the habit and the question stops being "can I claim this?" and becomes "logged it, moving on."
This is general guidance, not tax advice. What you can claim, and how, depends on your country's rules, so confirm the specifics with your accountant or local tax office.
