How do I apply for the Colorado TABOR tax credit if I've already filed?

You will have to amend your Colorado state tax return; you must claim the state sales tax refund (TABOR refund) when filing your state income tax return.

The refund is $800 for one qualifying taxpayer or $1,600 for two qualifying taxpayers filing jointly.

You should wait for your original state return to fully process before you amend it.
