No matter what, you need to retain a CPA firm for your business.  Find a cheap Panjabi/Indian CPA

who is willing to take your business account for $350 /$400 monthly. And they would do all tax filling

such as payroll,FUTA, 941 Employers Quarterly tax filing, end of the year tax filing report, Audit for you

business Insurance coverages, sometimes you have to deal with State govt Department of tax

assessment ( since 3 of you guys are H1B investors). They are certified to handle all legal tax matters. No worries.

At the beginning, CPA knows how to file Articles of incorporation  base on clients legal status in US,

what happens when there is a lawsuits claims, GC is permanent resident, he is ok, but H1B are not

permanent resident, what are the side effects on immigration case, etc.,

Good luck!!!
