ST3 tax increase calculator

Sound Transit 3 would require sizable tax increases to fund 56 more miles of light rail, plus commuter train and express bus extensions. To find your estimated 2017 tax increase:

Enter your assessed property value for the 2017 tax year, as shown on the notice mailed this summer by your county assessor.
Enter your household income to find an estimated sales-tax increase. These are derived from federal studies of consumer spending patterns, plugged into a Washington state government tax model, roughly broken out by income bracket.
Enter the amounts listed as “RTA tax” that you paid as a fraction of your most recent car-tab bill or bills. If your green car-tab bill isn’t available, you can find the official amounts by entering your license plate number here.
