How Does the Bellingham Property Tax Calculator Work?

Use this Bellingham property tax calculator to estimate your annual tax bill. Enter your property's assessed value and our calculator applies Bellingham's median effective tax rate of 0.81% — based on actual property records in Whatcom County — to generate your estimate.

Enter your property's estimated assessed value — the figure the local appraisal district uses to calculate your bill, which reflects any exemptions you hold and is typically lower than your home's market value. Our calculator applies Bellingham's median effective rate across all local levies, providing a more accurate estimate than applying a single county millage rate.

Your bill may vary by ZIP code within Bellingham: rates range from $4,497.00 in 98226 to $5,021.00 in 98229, primarily due to differences in school district levies and local assessment districts.
