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.
This page collects photo evidence of expired plates 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.
