We cannot render the service of a detailed tax consultation at this point. We are not allowed to give any legal or tax advice. We can just say that much: the tax rate of the US corporate tax for companies that are registered in the US and have their principal office there, is 21%. There might be additional taxes from the US States which vary from 0-12%.
Each corporation that has its principal office in the US, officially does business from the US and bills clients, can pay at these tax rates for its income in the US. There is no purchase tax, no licence tax, and no sales tax in Florida. Only if you sell products to the end-consumer in Florida do you have to charge sales tax to the client, which is paid to the state.
