Four dates. That is what May 2026 gives Social Security Disability Insurance (SSDI) recipients to work with. Which one applies to any given person comes down to two things: when they first signed up for benefits, and whatever day of the month they happened to be born on. Nothing else determines it.
People who were already collecting SSDI before May 1997 get paid on May 1. That same date carries SSI payments this month — an overlap that shows up occasionally when the calendar stacks the legacy third-of-the-month schedule against the first-of-the-month SSI window. No policy shift caused it. It’s arithmetic.
Everyone else — meaning anyone who enrolled after April 30, 1997 — lands on one of three Wednesdays: May 13, May 20, or May 27, depending entirely on their birthday.
Birthday ranges for SSDI beneficiaries
Born between the 1st and the 10th? The deposit comes on the second Wednesday of the month. In May that’s May 13. Birthdays from the 11th through the 20th go to the third Wednesday, May 20. Anyone born between the 21st and the 31st waits until the fourth Wednesday, May 27.
Late deposit? The agency’s guidance insists that you must wait up to three full business days before making contact. Banks account for a meaningful share of delays. Most sort themselves out.
What the 2.8% adjustment actually did to monthly checks
The cost-of-living adjustment applied to 2026 SSDI benefits came out to 2.8%. The SSA derived that number from CPI-W movement — the Consumer Price Index tracking urban wage earners and clerical workers — measured between the third quarter of 2024 and the third quarter of 2025. Every current recipient got the increase automatically with their January payment.
Run the numbers on that and you get an average monthly disability benefit of $1,630 for a single disabled worker. The year before it sat at $1,586. The difference is $44. For households where a spouse or children draw auxiliary benefits off the same earnings record, the average combined figure climbs to around $2,937 monthly.
The ceiling for 2026 is $4,152 per month. That’s the hard top. It went up from $4,018 in 2025. Getting there requires a long work history at consistently high earnings — most recipients never come close, because SSDI calculations run through a worker’s Average Indexed Monthly Earnings, not a standardized flat rate.
Federal SSI rates after the cola adjustment
Supplemental Security Income runs on its own math. The federal SSI maximum for an individual landed at $994 per month for 2026, climbing from $967. Couples where both partners qualify can receive up to $1,491, compared to $1,450 the year prior.
Those are federal floor numbers. A handful of states layer additional payments on top. And anyone with outside income — wages, other benefits, in-kind support — typically receives less than the published maximum, because SSI counts most income sources against the benefit.
The payment calendar for SSI doesn’t follow the birthday-based Wednesday system. It runs on the first of the month, pushed to the prior business day whenever the first falls on a weekend or holiday. May 1 covers it this cycle.
Earnings limits for recipients who work
SSDI doesn’t prohibit work outright, but it draws a line. The Substantial Gainful Activity threshold for 2026 sits at $1,690 per month for non-blind recipients. Cross that figure and the SSA treats the person as capable of gainful employment, which puts continued eligibility in question. Blind recipients operate under a higher ceiling: $2,830 monthly.
There’s a buffer built into the rules. The Trial Work Period lets recipients earn above the SGA limit for up to nine months without automatic suspension of benefits. In 2026, a month counts toward that nine-month window once earnings hit $1,210 — the threshold went up from $1,160. Those months don’t have to run back to back, but they must fall inside a 60-month rolling period.
