How do I calculate my household's tax amount?

Local levy and bond tax amounts are calculated using the assessed value of property. You can calculate your household's tax amount by multiplying the tax rate for the year by your home's assessed value as calculated by the state's tax assessor's office.

For example, if the tax rate for the year is $2.36 per $1,000 of assessed property value and your home's assessed property value is $150,000, you would calculate your tax rate as follows:

  1. Divide your home's assessed value of $150,000 by $1,000 = 150
  2. Multiply the tax rate of $2.36 x 150 = $354.00

Your individual tax amount in this example is $354.00 for the year or just $29.50 a month.

You can look up your home's assessed value by referring to your most recent assessor's notice or by entering your home's street address on Clark County's GIS System Website or Cowlitz County's GIS System Website. After entering your address, the websites will provide you a report including your property's Assessment Data.
