Every major freelance platform charges fees, and understanding the structure before you price your services is the difference between a profitable project and one that pays less than you expected. Upwork charges a freelancer service fee between 0% and 15% per contract, set based on factors the platform uses to maintain a balanced competitive environment, and the fee is fixed once a contract begins so there are no mid-project surprises. Fiverr takes a flat 20% service fee on everything you earn through its marketplace, deducted automatically when a client's payment is paid out — a straightforward structure but a significant cut that needs to be factored into your rates before you publish a gig. Guru sits at the lower end, charging between 5% and 9% based on earnings per project, with membership plans available that can reduce per-project fees further in exchange for a subscription cost. The practical implication is that if you want to net a specific hourly or project rate, you need to work backwards from the platform fee to set your listed price accordingly rather than pricing at your target rate and absorbing the difference.The tax angle most freelancers miss is that platform fees are typically deductible as an allowable business expense, since they relate wholly and exclusively to finding work. Whether you pay a membership fee or have a percentage deducted from earnings, both categories generally qualify as business expenses that reduce your taxable income.

Using a freelance platform also does not change your employment status — you remain self-employed regardless of where you find clients, which means Self Assessment registration and tax returns are still your responsibility. If you are unsure about how platform fees interact with your specific tax situation, a qualified accountant familiar with freelance finances is worth the investment, particularly as earnings grow and the fee and expense tracking becomes more complex.
