Income tax

Rhode Island charges corporate income tax at 7% of taxable income, with a $400 minimum. You owe whichever is higher, and the minimum applies every year you’re registered, even if your company had no revenue or operated at a loss. The $400 is not added on top of the calculated tax. It’s a floor.
Example:
ScenarioTax owedWhy
Not profitable$400Minimum applies
Profitable, tax calculates to $350$400Below the minimum
Profitable, tax calculates to $500$500Above the minimum

Registration

If your company has employees, property, or sales in Rhode Island, you’re required to register with the state. If you’re incorporated outside Rhode Island (like most startups incorporated in Delaware), you register through a process called foreign qualification. This tells Rhode Island that your out-of-state company is doing business there.

​
How to register

  1. Appoint a registered agent with a physical address in Rhode Island.
  2. Obtain proof of good standing from the state where your company was incorporated, dated within 60 days.
  3. Register online through the Rhode Island Secretary of State and pay the $310 filing fee.
Processing typically takes 1–3 business days. You can confirm your registration by searching the business database. For full instructions, see the Rhode Island registration page.

What registration triggers

Once registered, your company must file Rhode Island corporate income tax returns and pay state income taxes each year. Withdrawing your registration is its own process, so only register when you actually need to.
