Baby boomers are sitting on at least $93 trillion in assets, according to Visa's research team. That's more than Gen X and millennials hold combined.
A large piece of that, somewhere between $18 trillion and $20 trillion, sits in traditional IRAs and 401(k)s. Every dollar in those accounts is pre-tax. Nobody has paid a cent of income tax on any of it.
Their kids will.
Congress passed the SECURE Act in December 2019, and it eliminated something planners used to call the stretch IRA. Before that law, an heir could stretch withdrawals from an inherited IRA across their own life expectancy. A 40-year-old could pull small amounts out for decades and stay in a low tax bracket the entire time.
That option is gone for most heirs now. If you inherit a traditional IRA or 401(k) from someone who isn't your spouse, the account has to be empty within ten years. Not a lifetime. Ten years. And under the IRS's final regulations, which took effect for the 2025 distribution year, you often can't even wait until year ten to start: if the original owner had already begun required minimum distributions, you owe withdrawals in years one through nine too, with whatever's left coming out by the end of year ten.
Picture a 40-year-old named Sarah, a full-cycle AE working base plus commission, having the best year of her career. Her father dies and leaves her his $1,000,000 traditional IRA. The clock starts the day she inherits it, not the day she's ready to deal with it.
Split evenly, that's $100,000 a year for ten years, on top of whatever she already earns. Most people don't split it evenly, though. They wait, because the balance keeps growing and nobody wants to trigger a bigger bill sooner than they have to. Then panic sets in around year eight or nine, and the withdrawals turn lumpy: small early on, enormous at the end, right when the IRS forces the rest of it out the door.
Either way, the money lands during her highest-earning decade. Her commission checks already push her toward the top of her bracket most years. Now stack six figures of ordinary income from an inherited IRA on top of that, every year for ten straight years. The IRS taxes inherited IRA withdrawals as ordinary income, the same as a paycheck, with no favorable capital gains rate to soften it. It just gets added to whatever she already made and taxed at her marginal rate, which by year three or four might sit at 32% or 35% instead of 24%.
Multiply Sarah's situation across millions of households, and you get a real number. Depending on which estimate you trust, the accelerated tax revenue from this shift lands somewhere between $1 trillion and $3.5 trillion over the next decade. Call it $2 trillion. Boomers spent 40 years deferring that tax bill. Their kids get ten years to pay it, whether or not it fits anywhere into their financial life.
I want to be clear about something here: I'm not writing this because I feel bad for people who inherit money. Getting handed $1,000,000 is not a hardship, even with a tax bill attached to it. What actually bothers me is how few people see the bill coming. Passing a traditional IRA to your kids used to be a slow, gentle handoff. Now it's a forced ten-year unwind, and most families are still planning as though the old rules apply.
What actually helps
None of this is fixable after someone dies. By the time an account is inherited, the ten-year clock is already running, and the tax code doesn't care what else is going on in the heir's life that year. Everything that actually moves the needle happens earlier, while the original account owner, a parent or grandparent, is still alive and still has some say over how the money is structured.

The most direct lever is a Roth conversion. Every dollar a parent converts from a traditional IRA to a Roth while they're alive is a dollar that never lands on their kid's ten-year clock. The parent pays the tax now, at their own rate, ideally in a year when their income is lower. The first few years of retirement, before Social Security and required minimum distributions kick in, tend to be the sweet spot. Spreading the conversion across several years instead of doing it all at once keeps the parent from getting pushed into a bracket higher than necessary. Whatever comes out the other side grows tax-free and passes to heirs tax-free, with no forced ten-year withdrawal attached.
There's a narrower tool worth knowing about too: the qualified HSA funding distribution. It lets someone move money from a traditional IRA directly into an HSA, once, up to that year's HSA contribution limit, with no tax owed on the transfer itself. It only works if the person has an HSA-eligible high-deductible health plan, and it's a once-in-a-lifetime move, not something you repeat annually. It won't put much of a dent in a $1,000,000 balance, but paired with everything else, it's free tax reduction that most people never touch because they don't know it exists.
How the account is titled matters as well. A surviving spouse who inherits an IRA can treat it as their own and keep following the old rules, so a beneficiary form that routes everything to a spouse first, then to kids later, buys the family another generation of flexibility. Naming a properly drafted trust as beneficiary can also control the pace of distributions when an heir might otherwise drain the account too fast, though trusts add cost and complexity that only make sense for certain families. This one belongs in a conversation with an estate attorney, not a decision made off a newsletter.
If you're already the one inheriting
If the account is already yours and the ten-year clock is already running, you still have some control over how the pain lands. You don't have to wait until year ten and take it all at once, and you don't have to draw it down evenly either. Look at your own income across the decade and time the bigger withdrawals for the years your salary dips, you're between roles, or a slow quarter drags your commission down. Pull less in the years you're closing your biggest deals. You're still paying the tax either way. You just get to choose which years absorb it.
The $18 trillion sitting in boomer retirement accounts isn't going anywhere until it gets passed down, and when it does, the SECURE Act decides how fast the tax bill comes due. Families who talk about this while the account owner is still alive get to shape that timeline. Families who wait find out how the ten-year rule works from a CPA in April, after most of the choices are already gone.
