How can I get the withholding amount for prior years 2002 and 2003 for the state of Colorado?

“How can I get the withholding amount for prior years 2002 and 2003 for the state of Colorado?”------> You mean the tax refunds for your 2002/2003 CO returns?? I don’t think yo can claim your refunds form CO; You ,a s a Tax payer, must file any claim for refund or overpayment credit of Colorado income tax not later than one year after the expiration of the time provided for filing a claim for refund of federal income tax(Taxpayers must file a claim for a tax refund by the later of three years from the date you file the tax return or within two years of paying the tax. If you do not make the claim within this time frame, the IRS has the authority to reject the refund request). If a tax return is filed prior to the due date of the return, then the return is considered to have been filed on the due date for purposes of the statute of limitations.
