How do I fix Colorado Reject "23-104-026" on a Colorado 104 Individual return?
On February 23, 2024, it was brought to our attention that certain individual CO returns transmitted with an amount on line 21, "CO Income Tax Withheld from W-2s and 1099s," of CO Form DR 0104 received CO reject "23-104-026." An update was released February 24, 2024, correcting this issue. After installing updates, preparers should recalculate and retransmit affected returns.
