What ended it, and precisely for whom. Section 401 of the SECURE Act, signed in December 2019, added section 401(a)(9)(H) to the Internal Revenue Code and replaced the life expectancy payout with a ten-year deadline for most beneficiaries. It applies to deaths after 2019. That single detail is the one most often stated too bluntly: "the stretch IRA is gone" is not true as a general statement, because the trigger is the original owner's date of death, not the beneficiary's conduct or the current calendar year. A beneficiary who inherited from someone who died in 2017 and has been taking life-expectancy distributions ever since is doing it correctly today and will keep doing it correctly for decades. Nothing in the SECURE Act reached backward.
The two survivals. First, the grandfather: pre-2020 deaths continue under the old rules for the original beneficiary. Second, and more importantly going forward, eligible designated beneficiaries — a surviving spouse, a child of the owner until majority, a disabled or chronically ill individual, and anyone not more than ten years younger than the owner — were deliberately carved out of the ten-year deadline and may still use the life expectancy rule. So the strategy did not so much disappear as narrow to a defined list of people Congress decided should keep it.
Where a grandfathered stretch stops. It stops at the first beneficiary's death. When a beneficiary who has been stretching a pre-2020 inheritance dies, their own successor beneficiary is pulled into the 10-year rule, because that death occurred after 2019. The same is true of an eligible designated beneficiary's successor. A stretch, in other words, was never heritable; it was a payout schedule attached to one person.
What replaced the planning. The strategy's disappearance is why inherited pre-tax accounts now get attention they used not to need. When a large traditional balance must clear in ten years, the beneficiary's own earning years become the constraint — a 45-year-old at peak salary absorbing a compressed stream of ordinary income pays a very different rate than a retired 65-year-old would. The responses that came into common use afterward tend to sit on the owner's side of the ledger rather than the beneficiary's: Roth conversions during the owner's lifetime, so what passes is tax-free; naming charities for pre-tax dollars and other assets to individuals; and, less often than sales material suggests, trust and insurance structures whose costs have to be weighed against the deferral they buy.
