How to Do Business: Illinois, the USA, Canada and India
Step-by-step guides to starting a business in Illinois and to entering the U.S., Canadian and Indian markets: registrations, tax accounts, banking, hiring and profit repatriation.
Starting a business is a sequence of registrations: choose a structure, register the entity, get a tax identification number, register for state and local taxes, open a bank account, get licenses and permits, and put compliance deadlines on a calendar. The order and the offices differ by country, state and city, and mistakes in the early steps (the wrong entity, a missing foreign registration, a late annual report) are expensive to undo.
The Illinois guides walk through every step for a business in Aurora, Kane, DuPage, Will and Kendall counties and the rest of the state, with the real offices, forms and fees. The inbound guides cover what an Indian or Canadian owner must do to operate in the U.S., and the Canada and India guides cover the reverse. The last guide explains how to move profits and dividends between the three countries without surprises.
Deadlines live on the compliance calendars; local offices and county differences are in the Aurora and Illinois guides. We are a U.S. CPA firm and coordinate with your Canadian and Indian advisers for filings in those countries.
