Delinquency notices will now be mailed in June instead of September. King County will move up the annual mailing of property tax delinquency notices from September to June.
To avoid penalties, the first half of property taxes is due by April 30.
While there is no requirement to send a delinquency notice, for many years the County has sent a single courtesy notice in late September to about 9,000 taxpayers who missed the April deadline and whose taxes remained unpaid as of September 1. The September notice was timed to be close to the October 31 due date for the second half of property taxes owed and to help taxpayers avoid the eight percent penalty imposed in December.
The new June notice will go out to approximately 14,500 taxpayers.
