Calculating and Paying your Taxes

Estimating Your Property Taxes

You can roughly estimate what your future property taxes might be if you know the "assessed value" of your property and the most recent tax levy rate. Next year’s levy rates will change, however, use of the most current levy rate is appropriate for an immediate future best guess calculation. You will need to reference your property’s Tax Code Area (see Real Property Search or Tax Statement) and determine the most recent tax levy rate for that Tax Code Area in the Tax Book. For example, if the new assessed value of your property is $100,000 and the Tax Code Area is 0100 (most of the City of Bellingham) and the most recent Tax Levy Rate is $11.2831080518 per thousand dollars of value:

($100,000 / 1000) x 11.2831080518 = $1,128 estimated tax

How To Pay Your Property Taxes 

The County Treasurer mails property tax statements during February each year. The first half may be paid by April 30, and the balance by October 31, without penalties for late payment.

Many tax statements are sent to lending companies that require homeowners to maintain a property tax reserve account. If you do not receive your property tax statement, or if you know that your bank pays your taxes and you want to know the amount of your tax, contact the county treasurer's office.

You may pay your property tax to the County Treasurer in person or by mail. If you mail a check, be sure to include the tax parcel or account number on the check and include the tax statement's payment stub.

Property Tax Rates Differ

The amount of property tax due on comparable properties may be different throughout a county. Such differences are due to 3 factors:

  • The various combination of taxing districts in different areas of the county.
  • The amount of the budget for each taxing district.
  • The presence of voter-approved special levies and bonds.
