Income taxes are due to the extent that your company generates income.
Most of our customers buy a vehicle and sell it at a slight loss - i.e., they don't generate any income at all.
Furthermore, in 2020, the income threshold for filing a US federal tax return was $12,000. Those that earned less than that threshold during the calendar year were not required to file a return.
Owning a company in the US does not, by itself, create any income tax liability or require you to file a tax return.
