Darryl Pheasant, Treasurer, welcomes you to the Grant County Treasurerís webpage.


The county treasurer is the custodian of the county's money and the administrator of the county's financial transactions.


In addition to services for the county, the county treasurer provides financial services to special purpose districts and other units of local government, including the responsibility to receipt, disburse, invest and account for the funds of each of these entities. The treasurer receives and disburses funds, invests funds held and maintains financial records in accordance with accepted accounting principles. The county treasurer is also responsible for collection of various taxes, including legal proceedings to collect past due amounts. The county treasurer has other miscellaneous duties such as conducting bond sales and sales of surplus county property.




Statement by the Grant County Treasurer as to the 2018 MLIRD assessments Dated: July 26, 2018


The Grant County Treasurer is required by statute, RCW 87.03.270, to send notices of the Moses Lake Irrigation and Rehabilitation District (MLIRD) assessments by April 1 of each year and has done so for decades by including them on the Grant County general tax notices. This year, the Treasurer did not do that.


MLIRD used the same rate method in 2018 that it had in prior years. MLIRD's Board of Directors is authorized by RCW 87.03.445 to assess based on "rates or tolls and charges." For decades, the MLIRD Board has assessed based on the rates applied against the total assessed value of lands in the district. For decades, the Grant County Treasurer has included those rate≠ based assessments on the general Grant County Tax Notice.


There are pending legal issues between the MLIRD Board of Directors and the Grant County Treasurer which are currently in litigation.


The Treasurer has now agreed to send this statement to property owners, mortgage companies , escrow companies and other taxpayers . Please Note: Some mortgage companies do not pay assessments, and it is your responsibility to communicate with them.


Effective August 8, 2018,2018 MLIRD assessments will be able to be paid by on-line payments using a credit card. Checks will be processed by the County Treasurer as soon as practicable. No properties shall be placed in a delinquent status by the Grant County Treasurer, because of the delay of the mailing of the 2018 notices beyond the April 1, 2018 deadline and payments for the first half of the assessments were paid after the April 30, 2018 deadline.

The new deadline for payment of the first half of the assessments is August 31, 2018.


To accommodate taxpayers who are paying in person, our office will be open through the lunch hour from:
Monday 10/22/2018 through Wednesday 10/31/2018.

The deadline for 2st half 2018 property taxes is Wednesday, October 31th 2018.


A 5 (five) year tax history is available for parcels online. Access to Taxsifter is available by clicking on Parcel Information on this page. Search by last name or by entering the parcel number-, (without any dashes).
