Colorado wants more income tax, especially from small businesses. Start by collecting what it's already owed.

The state keeps asking for more income tax, and small businesses are first in line. Meanwhile, cars with expired temporary tags and expired plates drive every road in Colorado, and the registration fees they owe go uncollected.

Concerned Coloradans photograph expired plates they come across. This page collects that evidence and adds up an estimate of what's owed, using the state's own published fee formula.

This is an estimate. AI reads each vehicle's year, make and model from the photos, and the fee is calculated as a range across the likely model years using Colorado's published registration fee and specific ownership tax formula. Only the expired period is counted. Late penalties are left out. Every submission is reviewed before it appears.

Upload an expired plate

Add one photo or both: the full rear of the car, and a close-up where the tag or sticker date is readable. With just one photo, make sure the expiration date can be read in it. JPEG, HEIC, PNG and GIF all work. Location data is removed from your photos before upload. Submissions are reviewed before they appear.
