Did You Know...

The maximum regular tax rate is set by the state legislature. Excess levies or local levies
are approved by voters at the polls and include bond issues, maintenance and operation
and capital improvements. Voters within a district determine their own tax burden by
either approving or disapproving excess levy requests for money.

Washington state is not a Tax Lien state.

Payments under protest must be in writing and included with the timely property tax
payment (RCW 84.68.020 and WAC 458-18-215).

Voter-approved taxes are the result of an authorization by the voters during an election
process to levy excess taxes for a taxing district to finance Maintenance & Operation
expenses and/or to finance debt repayment for the applicable tax year.
