Congress is on the verge of passing a bill that aims to help Americans save more for retirement and leave their retirement savings untouched and untaxed for longer.

The bill nearing approval raises the age people are required to start withdrawing money from tax-deferred retirement accounts to 75 from 72. It increases retirement savings contribution limits for older workers and provides an increased incentive to people with low and moderate incomes to save in retirement accounts. It also paves the way for more employers to offer emergency savings accounts inside 401(k) plans.
