Mailing addresses for state tax agencies are available through the Federation of Tax Administrators’ website. The site links to each state tax agency, which provides taxpayers with tax forms and mailing addresses for their state.
An iPad app also provides links to state tax agencies and addresses, according to the Federation of Tax Administrators. These links are updated annually.

The information pages list mailing addresses for refunds, taxes owed, estimated taxes and amended returns. There are also links to forms, instructions and phone numbers.
