Grant County Property Tax Rates
Grant County property tax rates are set by the levy codes on each parcel. The Moses Lake area has several taxing districts, so the rate changes by location. The combined rate per $1,000 of assessed value is posted on the Assessor page.
Rates apply to the full assessed value, not the market value. If you live inside a city limit, you pay both city and county levies. If you live outside, the county rate still applies with a fire district levy added on.
How Rates Are Built
Each year, the county assessor uses the levy code map to group parcels. The levy rate comes from the budget ask of each district. The assessor then divides the budget by the total taxable value to set the rate.
- County general fund levy
- City of Moses Lake levy (inside city limits)
- School district levy
- Fire district levy
- Library and park district levies
Moses Lake Real Estate Tax Assessment
The Moses Lake real estate tax assessment is the value the county uses to bill you. The assessor revalues parcels in groups on a six year cycle. A physical check, sales study, and cost data all feed the model.
If you buy a home, the assessed value lags the market by up to two years. The assessor may adjust the value between cycles for new construction, fire damage, or zoning changes. You can ask for the valuation worksheet for any parcel.
What Triggers a Recheck
Several events cause the assessor to update the file mid cycle. A new deck, added square footage, or a land split all count. The change goes into the next tax year, not the current one.
- Building permit pulled for new work
- Sale of the property at a higher price
- Land split or boundary line shift
- Damage from fire, flood, or storm
- Zoning change on the parcel

Seniors aged 61 and up can claim a reduction on their primary residence. The income cap changes each year, so check the assessor page for the latest number. Disabled veterans with a service connected rating may also qualify for a full or partial exemption.

Moses Lake Property Tax Calculator
The Moses Lake property tax calculator 2026 uses the new assessed value and the levy code rates. You type the parcel value, pick the levy area, and the tool gives the annual bill. Use it to plan a refinance or a new home purchase.
The calculator pulls the latest rate from the assessor page. It includes city, county, school, and fire levies. The result is a close estimate, not the final bill.
How to Use the Calculator
You need the assessed value from the assessor search page. The tool also needs the levy area code for your parcel. Without that code, the estimate will be off.
- Look up your parcel on the assessor portal.
- Write down the total assessed value.
- Find the levy area code on the tax district map.
- Enter both numbers in the calculator box.
- Click the calculate button to see the annual bill.
Moses Lake Tax Foreclosure Process
The Moses Lake tax foreclosure process starts after three years of unpaid taxes. The county files a court action and gives public notice. You can still pay the back taxes, interest, and fees to stop the sale.
The Treasurer sends warning letters at the 30 day, 60 day, and 90 day marks. After three years, the property goes onto the foreclosure list. The sale date is posted on the county website and in the local paper.
Steps to Stop a Foreclosure
You can stop a foreclosure by paying the full past due amount. A payment plan is also an option in some cases. The key is to act before the sale date on the court order.
- Call the Treasurer as soon as you get a notice
- Ask for the total payoff amount
- Pay the full amount before the sale date
- Request a written receipt and lien release
Moses Lake Tax Delinquency Penalties
Moses Lake tax delinquency penalties start the day after the September 30 due date. Interest runs on the unpaid amount at the state set rate. The county also adds a flat fee for the late notice mailing.
The penalty grows each year the bill stays unpaid. After the first year, the interest rate can rise. The county also charges a cost for recording the tax lien on your parcel.
Penalty Schedule
Penalties post on the first of each month after the due date. The clock runs from the day the bill is past due. A partial payment covers the penalty first, then the interest, then the tax.
| Stage | Penalty Added |
|---|---|
| First 30 days late | 3% interest charge |
| Months 2 to 12 | State rate interest |
| Year 2 | Higher interest rate |
| Year 3 | Foreclosure filing fee |
Moses Lake Homestead Tax Relief
Moses Lake homestead tax relief lowers the taxable value on a primary residence. The state calls it the Home Valuation Reduction. The county assessor applies it to your parcel after you file the form.
The relief applies only to your main home, not a rental or cabin. You must own the home and live in it on December 31 of the year before. A spouse or co owner can also count as an occupant.
Qualification Checklist
You meet the test if you own and live in the home, and you do not claim a similar break on another state property. The assessor will check the voter roll and tax filings to confirm.
- Owned on December 31 of the prior year
- Used as the main home for at least 6 months
- No other homestead claim in another state
- No business use that covers more than half the space
Moses Lake Commercial Property Tax
Moses Lake commercial property tax rates apply to retail, office, and industrial parcels. The assessor uses a cost approach for most business properties. Income data may also feed the model for larger complexes.
Commercial bills are higher than residential bills in the same area. The value is based on building cost, land price, and rent income. The same levy codes apply on top of the higher base.
What Raises a Commercial Bill
New construction, added parking, and a higher rent roll can lift the value. The assessor reviews permits, sales, and rent studies each year. You can ask to see the income study the office used.
- New building or addition permit
- Lease renewal at a higher rent
- Sale of a similar property at a higher price
- Change in use from warehouse to retail
Moses Lake Residential Tax Rates
Moses Lake residential tax rates cover single family homes, condos, and duplexes. The rate per $1,000 is lower than the commercial rate. The base value is set by the sales of similar homes in the neighborhood.
Residential parcels get the same set of levy codes. The city, county, school, and fire district all apply. The total of all levies makes up the final rate on your bill.
Why Rates Change Each Year
The rate goes up when district budgets rise. It goes down when property values rise faster than budgets. You can track the rate change on the assessor’s tax district page.
- School district bond vote
- Fire district levy lid lift
- City of Moses Lake budget vote
- New construction adding to the value base
Moses Lake Tax Parcel Lookup
The Moses Lake tax parcel lookup tool finds a parcel by number, owner, or address. The tool lives on the Grant County property search page. It runs 24 hours a day and costs nothing to use.
Each search result links to a detail page with the full record. You can also link to a map view from the result. The map shows parcel lines, lot size, and the tax district boundary.
Lookup Tips
Use the parcel number for the fastest match. Address searches need the full street spelling. Owner searches work for the current or prior owner of record.
- Parcel number format: 000-000-000
- Address format: number then street then suffix
- Owner format: last name first or full name
- Map view opens in a new browser tab
Moses Lake Tax Assessment Appeal
You can file a Moses Lake tax assessment appeal if the value is too high. The State Board of Tax Appeals runs the hearing process. The county assessor handles the first review, called a petition for review.
The deadline to file a petition is July 1 of the tax year. You can file online, by mail, or in person. A late filing means the value stands for that year.
What You Need to Win
The board wants proof that the assessor value is too high. Sales of similar homes, an appraisal report, or rent data all help. A photo of a defect or damage also carries weight.
- Sale prices of 3 to 5 similar parcels
- Recent independent appraisal report
- Photos of damage or defects
- Rent data for income properties
Moses Lake Tax Payment Plan
The Moses Lake tax payment plan is open to owners who cannot pay the full bill at once. The plan splits the amount into equal monthly payments. A small fee and signed contract are required to start it.
You must pay current year taxes on time even on a plan. The plan covers back taxes only. Missing a plan payment ends the deal and the full balance comes due right away.
How to Sign Up
Contact the Treasurer’s office to request a payment plan form. Fill it out and return it with a down payment. The county then sends a payment book with the due dates.
- Call the Treasurer to ask for the plan form
- Fill in the parcel number and owner details
- Pay the required down payment
- Mail or drop off the signed form at the office
Moses Lake Property Tax History
Moses Lake property tax history shows past bills, rates, and value changes. The assessor keeps at least five years of record online. Older records need a visit to the records room or a written request.
You can use the history to check for billing errors. A line item that doubled year over year is a red flag. A phone call to the assessor can fix most data issues.
What the History Tells You
The history page shows the bill amount, the levy code, and the assessed value. It also lists any exemption that applied that year. The data updates after the assessor closes the roll each spring.
- Total bill for each tax year
- Assessed value of land and buildings
- Levy code and tax district for that year
- Exemption amount and type
Moses Lake Tax District Boundaries
Moses Lake tax district boundaries split the area into levy code zones. The lines follow city, fire, and school district maps. The assessor publishes a map viewer that draws the lines over the parcel layer.
A boundary change can move your parcel to a new levy area. The change takes effect on January 1 of the next year. The assessor mails a notice if your district code changes.
How to Read the Map
The map viewer has layers you can turn on and off. The parcel layer shows lot lines. The district layer fills the lot with a color tied to the levy code. A legend on the side lists the code for each color.
- Click the parcel to see the levy code
- Turn on the school district layer
- Turn on the fire district layer
- Use the legend to match the color to the code
Moses Lake Tax Refund Policy
The Moses Lake tax refund policy covers overpayments, duplicate payments, and errors. The Treasurer reviews refund requests and issues a check or applies the credit to the next bill. A written request with proof of the error is required.
Refunds for a closed escrow go to the buyer or seller based on the closing statement. A refund on a paid bill stays as a credit unless you ask for a check. Refunds older than three years may be turned over to the state unclaimed property fund.
How to File a Refund

Moses Lake Tax Lien Certificate
The Moses Lake tax lien certificate is a public notice that a parcel has unpaid taxes. The county files the lien with the Auditor’s office and posts it on the parcel record. A buyer of the parcel takes over the lien at the time of sale.
An investor can pay the back taxes and get a lien certificate. The certificate earns interest at the state set rate. If the owner does not pay back the taxes in the set window, the investor can start a foreclosure.
Buying a Lien Certificate
Lien certificates are sold at a public auction each year. The bid is the interest rate you will accept, with the lowest rate winning. You can bid online or in person at the Treasurer’s office.
