What the 2015 → 2026 changes mean for savers
More (or less) paycheck deferral room
The elective-deferral change of $6,500 (increase) is the maximum extra (or reduced) amount under-50 workers could elect from pay—before catch-up. Age-50+ catch-up moved $2,000.
IRA room is independent
IRA limits changed by $2,000. That room stacks with workplace deferrals, so a COLA on both sides can meaningfully raise total tax-advantaged savings capacity even if each individual jump looks small.
Watch §415(c) if you get a large match
Combined additions rose from $53,000 to $72,000. High earners with rich matches can hit this ceiling before they exhaust elective-deferral + catch-up room.
Super catch-up context
Ages 60–63 catch-up: n/a in 2015 vs $11,250 in 2026. Eligible participants use that amount instead of the regular age-50+ catch-up.

No in either year. Match and other employer contributions do not reduce your §402(g) elective-deferral room, but they do count toward the higher §415(c) annual-additions limit.
Yes for both years: Traditional and Roth share one annual IRA limit ($5,500 in 2015, $7,500 in 2026), plus catch-up if eligible. Roth contributions also face AGI phaseouts that change yearly.
