Rate Breakdown

Property taxes in Adams County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Adams County

Property taxes in Adams County are calculated based on the assessed value of your property and the applicable millage (tax) rates. The Adams County Assessor's Office determines your property's assessed value annually, which is typically close to its fair market value. This assessment considers factors like property size, location, improvements, and comparable sales in the area.

The total tax due is calculated by multiplying the assessed value by the combined millage rates set by local taxing authorities, including:

• County government
• School districts
• Fire districts
• Other special districts

Tax rates are expressed in "mills," where 1 mill equals $1 per $1,000 of assessed value. For example, a property valued at $200,000 with a combined rate of 10 mills would owe $2,000 annually.

Available Exemptions

Washington State and Adams County offer several property tax exemptions to eligible homeowners:

• Senior Citizen/Disabled Exemption: Low-income seniors (61+) or disabled individuals may qualify for reduced property taxes or deferrals.
• Veteran Exemption: Disabled veterans or their surviving spouses may receive partial exemptions based on disability rating.
• Homestead Exemption: While Washington does not have a traditional homestead exemption, the state limits annual property tax increases to 1% for primary residences under certain conditions.

Applications for exemptions must be submitted to the Adams County Assessor's Office with supporting documentation. Deadlines vary, so check with the office for specifics.

Payment Schedule & Deadlines

Adams County property taxes are billed annually and divided into two installments:

• First Half: Due by April 30
• Second Half: Due by October 31

Payments can be made online, by mail, or in person at the Adams County Treasurer's Office. Late payments incur penalties:

• 1-30 days late: 3% penalty
• 31+ days late: Additional 8% penalty (total 11%)

Delinquent taxes may result in a tax lien or foreclosure. If you cannot pay in full, contact the Treasurer's Office to discuss payment plans or deferral options.

Appealing Your Assessment

If you believe your property's assessed value is incorrect, you can appeal to the Adams County Board of Equalization (BOE). The process includes:

• Step 1: Review your assessment notice, mailed in mid-summer.
• Step 2: File an appeal within 30 days of the notice date. Submit evidence (e.g., recent appraisals, comparable sales) supporting your claim.
• Step 3: Attend a BOE hearing to present your case. The board will issue a written decision.

If unsatisfied with the BOE's decision, you may appeal further to the Washington State Board of Tax Appeals or county superior court. Consult the Adams County Assessor's Office for detailed appeal guidelines.
