How much taxes you will owe when you expand your business to the U.S.? The decisions you make prior to expansion will have an impact on what you have to pay after you begin (and as you continue) doing business in the U.S. Having a legal strategy or legal plan that examines U.S. tax situations will allow you to plan and/or strategize accordingly.  It can provide you with needed information to make the best decisions for your company’s business activities in the U.S. market.
