- Federal income tax = 22% x 50000 = 11000.
- State income tax = 0% x 50000 = 0.
- IRC 72(t) additional tax = 10% x 50000 = 5000 because the participant is under 59 1/2 and no exception applies.
- Amount kept = 50000 - 11000 - 0 - 5000 = 34000.
- IRC 3405(c) requires the plan to withhold 20% = 10000 at source; that is a prepayment of the tax above, not an extra cost.
