I'm working on-site at a help desk — is a 3.3% freelance contract actually correct for me?

If the client controls your hours and location and you're under their direct supervision, the reality may be closer to employment income, so it's important to review your contract type alongside your actual working arrangement. A common pattern is signing a dispatch contract for on-site help desk work as a freelancer (3.3%), while the actual reality involves strong attendance management from the client that resembles employment — and when the contract and reality diverge, it can later become a tax issue. Exam and renewal fees for vendor-certified credentials are recognized as necessary expenses, so we recommend reviewing your working arrangement before you sign a contract.
