It sounds superfluous because companies (well in AE) are always taxed by "income tax". I would take it out and say A company taxed at flat rate. Adding the "income tax" adds zero extra information.I believe you're right, timpeac. However, I need to combine flat rate and income tax somehow. As I said, income tax has undergone a process and as a result it's paid at a flat rate/basic rate while normally it's not paid like this. Maybe: A company taxed at a flat-rate income tax ? What do you say about this version?
