Rate Breakdown

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

How Property Tax Works in Grant County

In Grant County, property taxes are calculated based on the assessed value of your property and the applicable millage (tax) rates. Here's how the process works:

• Assessment: The Grant County Assessor's Office determines the market value of your property as of January 1 each year. This assessed value is used to calculate your tax bill.
• Tax Rates: Property tax rates (millage rates) are set by local taxing districts, including schools, cities, and county services. These rates are applied per $1,000 of assessed value.
• Calculation: Your tax bill = (Assessed Value / 1,000) x Total Millage Rate. For example, a $300,000 home with a combined rate of 10 mills would owe $3,000 annually.

Tax bills are typically mailed in February, with payments due in two installments.

Available Exemptions

Washington State and Grant 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, some programs reduce taxes for primary residences.

Applications for exemptions must be submitted to the Grant County Assessor's Office with required documentation.

Payment Schedule & Deadlines

Grant County property taxes are due in two installments:

• First Half: Due by April 30 (or next business day if weekends/holidays apply).
• Second Half: Due by October 31.

Late payments incur penalties:

• 1% interest for payments up to 30 days late.
• Additional penalties (up to 12% annually) for extended delinquency.
• Persistent non-payment may result in a tax lien or foreclosure.

Payment options include online, mail, or in-person at the Grant County Treasurer's Office.

Appealing Your Assessment

If you believe your property is overassessed, you can appeal to the Grant County Board of Equalization:

• Deadline: Appeals must be filed within 30 days of the assessment notice (typically July).
• Evidence Required: Provide comparable sales, appraisal reports, or photos of property defects.
• Process: Submit a written appeal form, attend a hearing, and receive a decision within weeks.

For complex cases, consider consulting a property tax professional. The Assessor's Office can also review errors without a formal appeal.
