Map of Earned Income Tax Credit by County

Following up on Dick’s last post, the Brookings Institution website has a cool interactive map with data on the federal Earned Income Tax Credit (EITC) by county (click on image):

In Washington state, King County has the smallest share of taxpayers taking the EITC (8.4%), while Yakima County has the highest share (22.3%). Brookings’s Ben Harris observes that:

There is notable variation across counties in EITC take-up. Ranked by share of taxpayers claiming the EITC, the bottom 10 percent of counties have claiming rates of 10.7 percent or lower, while the top 10 percent of counties have claiming rates of 27.1 percent or higher. The median county sees 16.2 percent of taxpayers claiming the EITC.

The size of the average EITC, among those claiming the credit, varies less than take-up rates. Most counties have average credits between $1,500 and $2,500: 10 percent of counties have average credit values of $1,657 or less, while 10 percent of counties have average credit values of $2,236 or more.
