An arm’s length transaction means charging the market value (the same amount you would charge an unrelated party).I'm not a tax professional - I trusted my accountant with it and I've had zero issues in the past 7 years of doing this. But the numbers were lower. Am I correct in assuming that I've got a bomb under my seat with the current US C-Corp structure?
However, it appears that you are eroding the tax base of the US corporation by not engaging in arm’s length transactions .
