The Social Security trust funds that about 67 million Americans rely on for benefits are scheduled to be depleted in 2034, one year earlier than was projected last year, according to the annual trustees' report released by the Treasury Department on Friday.
Unless Congress takes action, at that time, 80% of scheduled benefits will be payable from the combined funds for old age and survivors insurance and disability insurance.
The new depletion date comes as the trustees updated their projections for the U.S. economy to include recent output and inflation.
Meanwhile, Medicare's hospital insurance trust fund will be able to pay 100% of scheduled benefits until 2031, three years later than projected last year.
The White House earlier this month laid out a plan to extend the solvency of Medicare's hospital insurance trust fund, also known as Medicare Part A, which covers hospital, nursing facility and hospice services for eligible beneficiaries.
