Reassessments 2026

Initial property reassessments, May 2026.

Property assessment increases do not increase property taxes; rather, an increased municipal budget does. However, individual property taxes may increase or decrease independently of the budget if a property's value relative to other property values changes. What matters is not the value of a property, but its relative share of total taxable property value.

The real problem is that property taxes, in Geneva especially, are overweighted on taxing structures versus land. Property owners who improve their properties can expect to see their tax bills increase while someone who owns the same amount of land (i.e. has a state-granted monopoly on the world's most important rival good), and in what should be a prime location can expect to face a lower, maybe significantly lower tax bill (i.e. a $22k valuation for a larger lot than the nextdoor lot valued at $325k). The tax code, as it stands, rewards land hoarding and disincentivizes improvements.

As of 2026-05-17 it seems that Senate Bill S1131B is still in committee, which would allow municipalities to pilot land-value taxes.
