What is the EITC phase in, Obama wants to extend it?

He would extend the EITC phase-in range and increase the phase-out threshold for the childless, double the phase-in and phase-out rates for childless individuals paying child support; increase the EITC phase-in rate to 45 percent for families with three or more children, and increase the EITC phase-out threshold for married filers to $5,000. CDCTC would become refundable and low-income families would receive up to a 50 percent credit for childcare expenses. Saver's credit would be refundable and become a 50 percent match of the first $1,000 of savings, with phase-out beginning before $75,000
