The Social Security Administration announced it is moving back a deadline requiring stronger ID verification measures for beneficiaries looking to make changes.

Some 3 million Americans may benefit from higher Social Security payments beginning in April. In January, two provisions—the Windfall Elimination Provision (WEP) and the Government Pension Offset (GPO)—that reduced Social Security benefits for millions of workers were repealed after bipartisan efforts in Congress.

Right now, seniors pay taxes on Social Security benefits once their combined income exceeds $25,000 in the case of individuals, or $32,000 in the case of joint filers. Combined income is calculated based on adjusted gross income, tax-exempt interest income you collect, and 50% of annual Social Security income.
