Selling into another state can make your company owe that state’s income, franchise or gross receipts tax, not just sales tax. The checker below looks at each state’s bright-line test, your physical presence there and what you sell, then flags where you likely have nexus.

Check your state income tax nexus

See where your company may owe state income, franchise or gross receipts tax, based on each state’s bright-line test, your physical presence and what you sell.

Your activity by state, for the tax year

Standards last reviewed September 2026. Many states have no bright-line test and decide nexus from your activities; local taxes, pass-through entity rules and withholding for remote employees are not covered. Results are estimates for general information only, not legal, tax or financial advice. Confirm them with your own CPA, tax adviser or attorney before making decisions. Using this tool does not create a client relationship with Catching Numbers Inc.

How income tax nexus works

A state can tax your business income when you have enough connection, or nexus, with it. There are three common ways to get there:

  • Physical presence: an office, a warehouse, inventory (including inventory Amazon stores for you), or employees working in the state, including remote employees.
  • A bright-line economic test: about a dozen states set a dollar threshold, such as $500,000 of sales into the state, above which you have nexus even with no presence there.
  • Doing business in the state: most other states have no fixed threshold and look at your activities, which for services and software can mean regular sales to customers there.

What P.L. 86-272 protects, and what it doesn’t

Public Law 86-272 is a federal law that stops a state from taxing your net income if your only activity there is asking for orders of physical goods that are approved and shipped from outside the state. It does not protect services, SaaS or digital products, and it does not apply to gross receipts taxes such as the Washington B&O tax, the Ohio commercial activity tax or the Texas franchise tax. Several states, including New York, New Jersey and Massachusetts, now treat some online activities, such as post-sale chat support, as going beyond protected solicitation.

Frequently asked questions

Does selling SaaS into a state create income tax nexus?

It can. P.L. 86-272 only protects sales of physical goods, so a SaaS company that passes a state’s bright-line threshold, or does business there regularly, may need to file and pay that state’s income or franchise tax.

Does one remote employee create nexus?

Usually, yes. An employee working from a state is a physical presence, and it also brings payroll withholding and registration requirements in that state.

Which states have no corporate income tax?

Nevada, Ohio, South Dakota, Texas, Washington and Wyoming. Nevada, Ohio, Texas and Washington tax gross receipts or margins instead, so businesses can still owe tax there.

Is income tax nexus the same as sales tax nexus?

No. They are separate tests with different thresholds. Use our sales tax nexus checker for sales tax.
