How Credits Are Earned
The earnings amount needed for a credit changes annually. In 2026, one credit requires $1,890 in covered earnings, and $7,560 produces the maximum four credits for that year. Higher earnings can affect benefit calculations, but they do not produce more than four credits in the same year.
Use the threshold for each historical earnings year. It would be incorrect to divide earnings from years ago by the 2026 amount. Credits generally reflect annual covered earnings rather than a requirement to work a separate calendar quarter for every credit.
Total Work And Recent Work
SSDI insured-status rules examine the amount and timing of covered work. The familiar recent-work rule for many nonblind workers age 31 or older is 20 credits in the relevant 40-quarter period, together with the separate fully insured requirement. It is not the only possible rule.
Younger workers may qualify with less work. Statutory blindness has an important exception to the ordinary recent-work test. An individual review is preferable to rejecting a possible claim because an online checklist describes only a typical older worker.
What The Date Last Insured Means
Your date last insured generally identifies the end of disability insured status on your work record. A claim filed afterward may still be possible if the evidence establishes disability during the applicable insured period. Records from before that date can therefore be especially important.
The date last insured is not simply a date on which an existing approved SSDI benefit automatically ends. Continued entitlement involves other rules. Do not confuse insured status for establishing a new period of disability with the separate review of an ongoing benefit.
Check The Record And Other Pathways
Compare SSA’s earnings record with your wage and self-employment documents. Ask about missing earnings, name discrepancies, or corrections. Keep supporting tax and employment records rather than estimating credits from memory.
If you lack sufficient credits, ask whether SSI or benefits on an eligible family member’s record may apply. Those programs have their own requirements. Reviewing alternative eligibility can be useful, but it does not replace checking whether the earnings record itself is accurate or whether disability began while you were still insured.
