<prompt> Human: I dont understand the logic, could someone explain? As I thought, sending him money for a service is considered individual income. Which everyone has to pay on any amount they receive. So why is he asking me to pay for his individual taxes? This wasnt in the agreement when asking for his services. Im in US, hes in EU.  <response>: Sounds like the developer just figured out he didnt charge enough to cover his self-employment income tax. Tough shit. You agreed to 300. Thats all he gets, or he can go fly a kite and get nothing.
