Many think any retirement payout qualifies

→ Review plan documents

Box 1 of 1099‑R is gross, not net after taxes

→ Use box 1

Age requirement

Some think 55 is enough

→ IRS requires 59½ for 20% rate

RMD inclusion

RMD must be added to taxable amount

→ Use prior year Form 5498

Multiple lump‑sum payments

Each may need its own Form 4972

→ Check each distribution separately
