How Property Tax Works

Klickitat County, Washington operates under the state's property tax system, which serves as the primary funding mechanism for essential local services including schools, fire protection, libraries, and county operations. Property taxes in Klickitat County are based on assessed value, which is determined by the County Assessor and updated annually to reflect current market conditions.

The effective tax rate in Klickitat County typically ranges from approximately 0.8% to 1.2% of assessed value, though this varies significantly depending on your specific location within the county. Your actual rate depends on which special taxing districts serve your property, such as school districts, fire districts, hospital districts, and other local improvement districts. Properties in areas with more special districts will generally have higher overall tax rates than those in areas with fewer districts.

Supplemental Tax Bills

Supplemental taxes in Klickitat County are additional property tax bills issued when there are mid-year changes that affect a property's assessed value. The most common triggers include ownership changes (such as sales to non-family members), completion of new construction, or additions/improvements that increase the property's value after the January 1st assessment date.

When a supplemental assessment is issued, the tax is calculated based on the difference between the old and new assessed values, prorated for the remaining months in the tax year. For example, if you complete a $50,000 addition in July and your tax rate is $10 per $1,000 of assessed value, you would owe approximately $250 ($50,000 ÷ 1,000 × $10 ÷ 2) for the remaining six months of that tax year. Supplemental tax bills are typically due 30 days from the issue date and cannot be paid through existing escrow arrangements.

Escrow & Property Taxes

Most mortgage lenders in Klickitat County require property tax escrow accounts for borrowers with less than 20% down payment. Your lender collects monthly payments equal to 1/12 of your estimated annual property tax bill, holds these funds in an escrow account, and pays your taxes directly to the county when due on April 30th.

Lenders typically conduct annual escrow analyses to ensure adequate funds are collected, which may result in payment adjustments if your property taxes increase or decrease. If your escrow account has a shortage, you may be required to make up the difference through a lump sum payment or increased monthly payments over 12 months. Property owners should verify that their lender has made the payment by checking with the Klickitat County Treasurer's office, as you remain ultimately responsible for ensuring taxes are paid on time even when using escrow services.
