The detail
What it means in practice.
The law doesn't define the phrase. Courts and the IRS look at whether activity in the US is considerable, continuous and regular: an office, staff, a dependent agent who can sign contracts, or inventory held and sold there. Forming a company in Wyoming doesn't create one, but running a warehouse in Ohio might. It's worth putting the question to an accountant once.
