Hi Madan,
Thanks for the helpful website. I am a Canadian and planning to set up an E-Commerce(on-line) business in the USA.
-Is it better to do online business in the USA with USA entity Or with Ontario based Corporation? Which is more tax-efficient?
– If I go With US C-COrp I won’t have any physical presence in the US, So will I pay federal sales tax and income tax in the USA as Canadian?
-Should I first register my Corp in Ontario and make another C-corp in the US later?
-Does your firm handle all the cross border tax filling and related issues of US C-Corp?
What is your advice? Would really appreciate your response
