Veterans Exemptions

Contact the Weston County Assessor to see if you qualify for Veteran Exemption for property taxes.

Tax Sale

Any land or property in which taxes have not been paid will be sold at the Tax Sale; scheduled for the last Monday of August each year.

The Weston County Treasurer uses a “bingo” system for the sale. Before the sale starts, each participant will choose a bingo number and place it in the cage. When your number comes up you can pick only one property tax to buy. Once all numbers have been drawn in the first round, any participant who would like to purchase more than one property tax can place their ball back in the cage. This continues until all taxes are sold.

Payments can be made with cash, check, money order or credit card. There will be a 2.5% processing fee for credit card transactions. American Express is not accepted.

Mobile Homes

When transferring ownership and/or moving a mobile home it is required to have the property taxes paid in full through the current year. A Transportable Mobile Home Move Sheet must be obtained with the original title from the County Treasurer.
