100 days to December 31.
OCTOBER — anything payroll-dependent.
S-corp wage corrections, W-2 wages for a retirement contribution. Payroll has to actually process. Late-December runs are real and they're stressful.
BY DEC 31 — the retirement plan.
Must EXIST. Funding can come later. The most commonly missed window I see.
BY DEC 31 — placed in service.
In use. Not ordered, not paid for.
BY DEC 31 — the accountable plan.
Adopted before you reimburse. Forward only.
BY DEC 31 — Augusta Rule meetings.
They have to actually happen.
JAN 15 — Q4 estimate.
Two calendar entries: one in October, one the first week of December.
Six of these are decisions. Not paperwork.
