New York EITC

The New York EITC equals 30 percent of the federal EITC, minus the New York household credit.

Examples

The New York EITC provided up to $2,000 in 2021, for a joint filer with three children and earnings between about $25,200 and $26,100. It is not smooth because it subtracts the New York household credit, which falls with income in a stepped manner.
