Below are links to the state tax agency website for every state. This is the state agency in charge of the state's tax filings, reporting, and collections. Every state has its own tax laws that business owners in that state must comply with. In most states, businesses must register with the state tax agency and apply for state tax permits. In addition, business owners have certain tax obligations they must pay, such as an income tax and employment tax. You can usually find all the information you need about your business tax obligations through this agency, including tax filing requirements, tax rates, forms, and other business tax-related matters.
