Three things inside every pre-tax account

The statement shows a balance of $5 million, so a family naturally expects to have $5 million. That isn't the full picture. A traditional pre-tax retirement account contains three things: your accumulated pre-tax savings, the earnings on those savings, and a future income tax obligation on the entire balance.

The taxes were deferred while you were working. They weren't eliminated. Tax deferral may have been extremely valuable during your career. The problem is letting the same accumulation strategy run on autopilot after retirement.

The default path

Imagine you retire in your early 60s with $5 million in pre-tax accounts, and because you don't need the money, you leave it untouched. Assuming, for illustration only, a 6% average return, the balance could be close to $9 million after 10 years.

Under current law, required minimum distributions generally begin between age 73 and 75, depending on your year of birth. With a $9 million balance, the first required distribution could be around $340,000, taxed at ordinary income rates and stacked on top of Social Security, pension income, dividends, rental income, and anything else.

That can reverse the original logic of tax deferral: you took deductions in a high bracket, only to have money forced out later at rates that are just as high, or higher. And the problem can continue after death. Most adult children must empty an inherited account within 10 years, often during their own peak earning years. The parents received the deductions decades earlier; the children may inherit a concentrated tax bill.

The income valley

For many successful families, the most valuable tax planning window opens after the paycheck stops and closes when required distributions become large. We call it the income valley. Salary and bonuses stop, business income may fall, Social Security may be delayed, and RMDs haven't started. For the first time in decades, there may be room in lower tax brackets.

That room isn't automatically a benefit; it's capacity, and it expires every December 31. Unused bracket space can't be carried forward. That's why planning should start with a multi-year projection that runs from the final working year through both spouses' lifetimes, including what happens after the first spouse passes away. A surviving spouse filing single may face a higher marginal rate on similar income, sometimes called the widow's penalty.

A multi-year Roth conversion strategy

One potential solution during the income valley is a deliberate series of Roth conversions. In selected years, you move a measured amount from a traditional account to a Roth account. The converted amount is generally taxable that year, so a conversion isn't free. You're choosing to pay tax sooner because doing so is expected to produce a better result than paying it later.

• Convert enough to fill part of a selected bracket, then stop.
• Decide deliberately whether to cross or stay below a Medicare (IRMAA) threshold.
• Coordinate with other events: a large charitable deduction, a business loss, a low capital-gain year, the years before Social Security, or a move to a lower-tax state.
• Plan how the tax will be paid. Paying from taxable assets keeps the full conversion invested in the Roth, but selling investments or using cash has its own cost.

The value comes from repetition. A coordinated series of conversions over eight to ten years can shrink future RMDs, move future growth into the Roth, and build a pool of assets that may be withdrawn tax-free.

For very large accounts, the analysis should also ask what tax rate your children might pay if they inherit the account while it's still pre-tax. If heirs are high earners in high-tax states, conversions can look more attractive across the family. If the beneficiary is a charity, an heir has little income, or the money will be spent during your lifetime, they may not. Roth conversions are a modeling decision, not an automatic recommendation.

Qualified charitable distributions

If your family already gives to charity, your IRA may become an efficient source for that giving. Once an IRA owner reaches age 70½, they may be eligible to make a qualified charitable distribution (QCD) directly from the IRA to an eligible charity. When done correctly, it can count toward the year's RMD and is generally excluded from taxable income. That's different from taking a withdrawal and donating it yourself.

The rules matter: funds must generally go directly to an eligible organization, donor-advised funds generally don't qualify, and there's an annual limit, $111,000 per person for 2026. QCDs can work naturally with a conversion plan: conversions do most of the work during the income valley, and QCDs help manage taxable income after RMDs begin.

Which account pays for spending?

The common rule says to spend taxable accounts first, traditional accounts second, and Roth accounts last. It's a useful starting point, not a complete plan. For a family with an unusually large pre-tax account, following it automatically may let that balance grow into the exact problem you're trying to avoid.

During conversion years, taxable assets may fund living expenses and conversion taxes. In another year, an extra traditional IRA withdrawal may be better. In a high-income year, spending from taxable or Roth assets may protect an important threshold. The right order can change every year.

Execution is the whole strategy

The biggest threat to this plan may not be complexity. It may be the calendar. No one warns you when a valuable conversion year is about to expire. A family converts in year one, converts less in year two, then markets move or life gets busy, and by January the opportunity is gone.

1. Map the income valley from your final working years through RMD age and the surviving spouse's later years.
2. Run a whole-life comparison that includes your tax rates, your heirs' possible rates, state taxes, charitable goals, spending needs, and how conversion taxes will be paid.
3. Give every account a job: which funds spending, which may be converted, which is preserved, which goes to charity, and which is intended for each beneficiary.
4. Create an annual rhythm. Update the projection early in the year, estimate the conversion range in the second half, coordinate with your CPA, and complete everything before the deadline.

The goal isn't to convert every dollar or avoid all taxes. It's to make informed decisions before the opportunities expire. Don't let tax deferral continue by accident. Decide what you want the account to become, then build the plan around that decision.
