Welcome from Columbia County Tax Collector Mary Ann Guess

The Columbia County Department of Taxation would like to Thank you for visiting our webpage for the Columbia County Tax Office. Please be assured that our department is committed to using a safe and accurate collection and timely deposit of Columbia County property tax dollars to fund municipal entities that serve the community. It is the responsibility of the Columbia County Assessor to determine the value of all property according to state law; prepare and certify the annual assessment roll for the County; and give this to the Tax Collector in October each tax year. The Department of Taxation then sends billing statements and collects all property taxes and penalties in the county and distributes the tax money to the taxing districts.

The Columbia County Department of Taxation strives to uphold Oregon law by safe and accurate collections and timely deposits of Columbia County property tax dollars to fund municipal entities that serve the community by distributing taxes accurately and providing public service with quality and creditable standards. Property tax payments are turned over to the County Treasurer for distribution to the public school districts, cities, fire protection districts, urban renewal districts and other municipal entities that serve the community within Columbia County.

Property Tax Discounts

Oregon Statute allows property tax payers to receive a discount for timely payment of tax. To receive the full discount of 3 percent, property taxes must be current for all prior years, and the current year tax assessment must be paid in full by November 15. Details on discounts and deadlines are noted on your tax statement. (Envelopes must be postmarked by November 15 to qualify for the 3 percent discount.)

In the event of non-payment of property taxes by the statutory due date, tax staff are responsible for computing interest, mailing notices, filing tax warrants and initiating collection activity.  In consultation with County Counsel, tax staff manage foreclosure proceedings and file claims for taxes in bankruptcy cases. The Tax Office is also responsible for the collection of prepayments for plats, potential tax, certified personal property and manufactured structures.
