A. First, what is a "stretch IRA"?
Before 2020, you could bequeath your IRA to anyone you wanted. The recipient has to take "required minimum distributions" every year. But those distributions, which are taxable, could be stretched out based on the recipient's presumed life span. The younger the recipient, the smaller the distributions the inheritor has to take.
So a "stretch IRA" is a perfect tool could be used to pass assets to people two or three generations younger, no estate tax.
However, from January 1, 2020, under the new rules, stretch IRAs for non-spouses were pretty much eliminated - it limits the life of bequeathed IRAs to 10 years if you give them to anyone but a surviving spouse or sick or disabled beneficiaries.
The Solution
So what you can do? If you have the money, you can create a "synthetic stretch IRA" by setting up a trust to which you bequeath your IRA, with the trust instructed to pay lifetime income to whomever you choose on whatever terms you like.
