A Colorado filing requirement change for partnerships and S corporations, effective tax year 2022, requires Colorado K-1s (DR 0106Ks) along with a transmittal form (DR 1706) be submitted SEPARATELY from the Colorado tax return (DR 0106); separate mailings, different addresses.
TurboTax instructions for filing 2022 forms by mail (can't submit electronically via TurboTax), reflect a single mailing to a single address. This is incorrect. Instructions also don't mention signatures required in two places, for both form DR 0106 and DR 1706.
DR0106 filing (no tax payment) is to be mailed to:
Colorado Department of Revenue
Denver, CO 80261-0005
Transmittal of K-1s is to be mailed to:
Colorado Department of Revenue
Denver, CO 80261-0006
