SIMPLE 401(k) room 2026: $8,000 already in leaves $9,000 at age 40

SIMPLE elective cap is $17,000 in 2026, not $24,500. $8,000 YTD leaves $9,000 under 50. Age 52 leaves $13,000. Age 62 leaves $14,250. Pasting a regular 401(k) leftover overshoots.

A SIMPLE 401(k) or SIMPLE IRA is not the regular 401(k). IRS COLA 2026: elective deferral $17,000. Age 50+ catch-up $4,000 (total $21,000). Ages 60-63: $5,250 (total $22,250).

The empty-plan leftover is already written: $17,000 / $21,000 / $22,250. This page is the mid-year leftover: $8,000 already deferred.

  • Age 40: room $9,000

Wrong cap, excess deferral

If payroll coded you as SIMPLE and you aim at the regular $24,500 leftover, the extra is an excess deferral. This engine only subtracts YTD from the SIMPLE ceiling.

Direct answer: $8,000 YTD → $9,000 at age 40

  1. SIMPLE 2026 base = $17,000
  2. Age 40 catch-up = $0
  3. Room = $17,000 − $8,000 = $9,000
  4. Age 52 = $21,000 − $8,000 = $13,000
  5. Age 62 = $22,250 − $8,000 = $14,250
SIMPLE 2026 elective room

limit = $17,000 + ($4,000 if 50–59 or 64+, or $5,250 if 60–63)

remaining = max(0, limit − YTD deferrals)

Same $8,000 YTD, three ages

AgeCatch-upSIMPLE limitRoom after $8,000

52$4,000$21,000$13,000
62$5,250$22,250$14,250

A regular 401(k) after $8,000 still has $16,500 under 50 ($24,500 − $8,000). That is not this plan. Catch-up leftover on a regular plan: age 52 after $20,000.

What this is not

Yes, if YTD is $8,000 and the plan is SIMPLE. Confirm the plan document and payroll coding.

Age 50+ adds $4,000 of SIMPLE catch-up. $21,000 − $8,000 = $13,000.

Elective deferrals across plans share a combined 402(g) limit. SIMPLE plus regular 401(k) is not two full caps. Confirm with a preparer.
