State Corporate Income Tax Nexus: When Does a Business Have to File?

A corporation doing business in more than one state may have tax filing obligations outside the state where it was formed. Employees, property, offices, inventory, sales, and other business activities can potentially create a sufficient connection with another state for tax purposes.

Understanding state corporate income tax nexus is therefore an important part of expanding a business across state lines.

What is State Corporate Income Tax Nexus?

State corporate income tax nexus is the connection between a corporation and a state that allows the state to impose an income tax filing obligation on the business.

Nexus may result from physical presence, employees, property, sales, or other business activity, depending on the state’s rules. Because nexus standards vary by state and by type of tax, businesses operating across state lines should evaluate each state separately.
