If Congress doesn’t act, people receiving Social Security disability benefits could see a nearly 20 percent cut to payments at the end of next year, according to the latest version of the Social Security trustees report released Wednesday.

The disability trust fund will be depleted by the fourth quarter of 2016, leaving the administration with enough income to pay 81 percent of benefits, according to the report, which is updated annually.

The health of the Social Security program didn’t change by much, and the cut to disability benefits has been expected for years. But now that Congress has still not come up with a compromise for boosting the funding, the shortfall is more imminent.
