The dollar limit is a subtraction, not a cap. Section 72(t)(2)(I)(iii) sets the amount at the lesser of $1,000 or the excess of your total nonforfeitable accrued benefit under the plan, measured as of the date of each distribution, over $1,000. Read that as a floor you have to leave in place. With $6,000 in the account you can take the full $1,000. With $1,400 you can take $400. With $900 you can take nothing at all. Almost no consumer explanation of this provision mentions the subtraction, and it is the single most likely reason someone finds the route unavailable when they need it.
Two three-year periods, doing two different jobs. The repayment window runs three years from the day after you receive the money, during which you may put back up to the full amount and be treated as having rolled it over. Separately, clause (vii) says that once you take one, "no amount may be treated as such a distribution during the immediately following 3 calendar years with respect to such plan" unless the earlier distribution is fully repaid, or your contributions since then at least equal the part you have not repaid. That second clock is a lockout, not a deadline, and the escape hatch is generous: ordinary payroll deferrals of $1,000 over the following year satisfy it without you writing a check. These two clocks are widely described as one, and the conflation makes the rule sound stricter in one direction and looser in the other.
Where it is available. The provision reaches an "applicable eligible retirement plan," which the Code defines as an eligible retirement plan other than a defined benefit plan. That covers IRAs, 401(k) plans, 403(b) plans, and governmental 457(b) plans, and excludes traditional pensions. Notice 2024-55 states that offering the distribution is optional for a workplace plan, so it is a feature your employer's plan may or may not have adopted. That is less of a dead end than it sounds: the same guidance provides that where a plan does not permit these distributions, an individual may still treat an otherwise permissible distribution as an emergency personal expense distribution on their own return. For an IRA there is no plan to ask at all. One useful side effect: the distribution is not treated as an eligible rollover distribution, so the mandatory 20% withholding that applies to most workplace plan payouts does not apply. Ordinary non-periodic withholding under section 3405(b) still does, at a 10% default you can elect out of, so the amount that reaches your account is $900 unless you say otherwise.
IRS guidance is in Notice 2024-55, which addresses this provision alongside the separate distribution for victims of domestic abuse.
