- 1). Search the Internet for your state's "Department of Revenue," "Division of Taxation" or a generic "(state name) state taxes." For instance, if you live in Kansas, type in "Kansas state taxes," and it will bring up the Kansas Department of Revenue.
- 2). Look for the FAQs web page. It is likely that your state's taxation website will have the answer to your question listed in the "frequently asked questions." section, or a phone number to the exact department you will need to call.
- 3). Click on the "contact us" icon, which should be available on each state's website. This will direct you to a phone number where an employee can either verify the information for you, or direct you to someone who can.
- 4). Use the phone book. Old-fashioned, but effective, you can look up your state department of taxation in the phone book. In the "government" section, go to the state offices section. From there, look up "taxes", and find a number for your state's department of taxation.
