401(k) catch-up after $20,000 at age 52: $12,500 left, not $4,500

2026 elective deferral is $24,500 plus $8,000 catch-up at 50–59. Age 52 with $20,000 YTD still has $12,500. Age 40 has $4,500. Age 62 has $15,750 ($11,250 enhanced catch-up).

The regular employee elective deferral limit is $24,500 in 2026. Catch-up is extra, if the plan allows it: $8,000 at ages 50–59 and 64+, or $11,250 at ages 60–63 (SECURE 2.0 enhanced).

The leftover is room after $20,000 is already in, not the empty-plan comparison. After the $24,500 base, age 52 vs 62 is $8,000 vs $11,250.

Age 52, YTD $20,000:

  • Base $24,500 + catch-up $8,000 = total $32,500
  • Room left $12,500
  • Age 40 on the same $20,000: only $4,500 (no catch-up)
  • Age 62 on the same $20,000: $15,750 ($24,500 + $11,250 − $20,000)

Plan must allow catch-up

These are IRS 2026 elective-deferral figures. Employer match and the $72,000 annual-additions cap are different engines. Estimate, not plan or tax advice.

Direct answer: $20,000 YTD at 52 → $12,500 left

  1. Base limit = $24,500
  2. Age 52 catch-up = $8,000
  3. Total = $32,500
  4. Room = $32,500 − $20,000 = $12,500
  5. Age 40 room = $24,500 − $20,000 = $4,500
  6. Age 62 room = $35,750 − $20,000 = $15,750
Catch-up room (2026 elective deferrals)

total = $24,500 + catch-up ($0 / $8,000 / $11,250)

remaining = max(0, total − YTD deferrals)

Same $20,000 YTD, three ages

The IRA catch-up is a different dollar: $1,100 on top of $7,500. Workplace room here does not close the IRA. 401(k) maxed, IRA still $7,500.

What this is not

  • A match formula. Catch-up does not create employer match by itself. Match uses plan language and eligible pay.
  • A SIMPLE 401(k). That cap is $17,000, not $24,500. SIMPLE 401(k) $17,000.
  • Payroll tax relief. Traditional deferrals cut FIT, not FICA. 6% 401(k) on the stub.

Because $20,000 is still $4,500 under the $24,500 base. Catch-up $8,000 stacks on that leftover. $4,500 + $8,000 = $12,500.

No. The enhanced amount is ages 60–63 when the plan allows it. Age 52 uses the standard $8,000.

Yes. Both count toward the same elective-deferral cap.
