Generally speaking it is if you don't know where to begin. That's why we have put together a filing tool that caters specifically to non-resident U.S. business owners (NRAs) to help you navigate the complexity of these filing forms with much of the more complex fields pre-populated for your convenience and totals and sub-totals programmatically computed to help you through the process. Our tax filing tool will calculate the total you owe to the IRS for your U.S. business without the need for a costly paid manual tax preparation.
