Property owners have until Wednesday to pay the second half of their 2012 property taxes to avoid penalties.

Residents of King County may make their payments online at the E-commerce Property Tax Web page at www.kingcounty.gov/propertytax. The county warns that it may take up to two weeks for payments to be recorded.

In Snohomish County, residents may pay the county treasurer online at www.snoco.org using a credit card or electronic check. Same delay caution applies.
