Senior Citizen Exemption

Ages 65 and Older

Homeowners in Whatcom County who are 65 or older qualify for additional exemptions and, in many states, a tax freeze on school district taxes.

  • Age Requirement: Must turn 65 during the tax year. Some states allow prospective filing before your birthday.
  • Proof Needed: Birth certificate or state-issued ID required for first-time filing.
  • Tax Freeze: In many states, the school district tax portion of your bill is frozen at the value it was when you turned 65.

Veteran Exemptions

Disabled Veterans & Surviving Spouses

Whatcom County offers substantial relief to veterans with service-connected disabilities.

100% Disability Rating

Veterans with a 100% permanent and total disability rating often qualify for a complete property tax exemption on their primary residence.

Partial disabilities (10%–90%) qualify for tiered exemptions that reduce assessed value by specific dollar amounts.

Disability Exemption

Persons with Qualifying Disabilities

Homeowners under 65 who are disabled as defined by Social Security Act may qualify for the same over-65 exemption amount, including a school tax freeze.

💡 Tip

You can qualify for either the over-65 or the disability exemption, but not both simultaneously on school district taxes. Apply for whichever provides the greater benefit.

Local Option Public Benefit Rating System for Open Space

agricultural 90.0% Exemption

Preferential treatment: In addition to being valued based on current use, open space properties may be eligible for a property tax exemption based on a locally adopted Public Benefit Rating System (PBRS). PBRS defines both the criteria for evaluating the land for enrollment and the reduction rate such classification will have on the landowner’s property taxes. The system provides points based on the type or nature of the open space, the commitment of the land owner to retaining open space use, and the degree the public is granted access. Based on points awarded, assessments may be reduced up to 90%.. Penalty: At local option, a penalty may be imposed if the property no longer meets the program requirements. If the owner requests to remove their land from classification within 30 days of the PBRS value notification, then the land may be removed without penalty..

How to Apply & Eligibility

Eligible land uses: Agricultural/Farmland, Conservation/Open Space, Forest Land/Timber Production, Historic, Parks/Recreation, Other Land Uses. Eligibility: Prerequisite Designation or Certification, Other Eligibility Requirements. Plot criteria: None. Income criteria: None

Open Space Taxation Act - Farmland

agricultural 20.0% Exemption

Preferential treatment: In determining the current use value of farm and agricultural land, the assessor considers the earning or productive capacity of comparable lands from crops grown most typically in the area, averaged over at least 5 years. This earning or productive capacity is the “net cash rental” and is capitalized by a “rate of interest,” charged on long term loans secured by a mortgage on farm or agricultural land plus a component for property taxes. The current use value of land must be established as the prior year's average value of open space farm and agricultural land used in the county plus the value of land improvements, such as septic, water, and power used to serve the residence. This may not be interpreted to require the assessor to list improvements to the land with the value of the land.. Penalty: If the owner changes the use of land, they must notify the county assessor within 60 days of this action. The assessor will remove the land from classified status and impose an additional tax of the difference between the tax paid on the current use value and the tax that would have been paid on that land had it not been so classified for up to the prior 7 years. Interest will also be charged on delinquent property taxes at the same rate as the additional tax. Finally, a penalty of 20% of the total amount will be charged. If they are not paid, any additional tax, applicable interest, and penalty becomes a lien on the land at the time the land is removed from classification. If the land is within a special improvement district that has issued bonds, additional penalties apply.. Sources imported from Lincoln Institute agricultural treatment dataset.

How to Apply & Eligibility

Eligible land uses: Agricultural/Farmland. Eligibility: Plot/Land Size, Income Production, Management Plan, Multi-Year Commitment, Other Eligibility Requirements. Plot criteria: There are different income criteria for parcels under 5 acres, parcels 5 acres or more but less than 20 acres, and parcels that are 20 acres or more. If the land is less than 5 acres, used primarily to grow plants in containers, and more than 25% of that land is open to the general public for on-site retail sales, such land does not qualify as “farm and agricultural land.". Income criteria: If the parcel is less than 5 acres, it must have an annual gross income of $1,500 or more per year for 3 of the 5 calendar years preceding the date of the application for classification. If the parcel is between 5 and 20 acres, it must meet one of the following three criteria: (1) produced a gross income of $200 or more per acre for 3 of the 5 years preceding application for current use; (2) has standing crops expected to harvest within 7 years and investment in the production of these crops is $100 or more per acre in the current or previous year; or (3) it has standing crops of short rotation hardwoods expected to harvest within 15 years and investment in the production of these crops is $100 or more per acre in the current or previous year.
