You will need to provide some information in order to check your state refund status online, although it varies by state. Some states only require your Social Security Number and the amount of your expected refund; other states require your filing status, birthdate, and ZIP code as well. In most cases, you will need to enter the amount of your state refund in order to access its status, so make sure to have your state tax return information on-hand when you use the online tool.

Keep in mind that most states take at least 4-6 weeks to process tax returns after they receive them, whether electronically or through the mail. In states such as Illinois, extra precautions to protect taxpayers from identify theft have made the process longer than in the past. You can use the available options to check your state refund status, but expect to wait at least 4 weeks after e-filing (or longer if you file your return through the mail) to receive your state income tax refund.
