Income Tax Forms..
Notice: The Oklahoma Tax Commission is unable to mail forms to individuals or businesses. Please visit our Income Tax Forms site to download and print any forms needed.
If you filed a paper resident income tax (511) form for the previous year, you will be mailed a packet for the current year in early January. Otherwise, you will need to either download form(s) from our website or visit your area library.
Oklahoma libraries are being sent a CD of Oklahoma income tax forms that can be used to print the form(s) needed.
