Multiple planning architectures address the high-balance IRA tax-trap. Which one fits depends on your specific situation.
The tax problem facing high-balance traditional IRAs comes from three interacting forces: required distributions that begin at 73, the widow’s tax cliff when one spouse survives the other, and the SECURE Act’s 10-year rule that compresses inheritances into a decade of peak-earning tax exposure. Together these routinely send 50-65% of a traditional IRA’s principal to federal and state governments across the family lifecycle.
The natural next question is: so now what?
The honest answer is that there isn’t one answer. There are several planning architectures that address the high-balance IRA tax-trap, and which one fits your family depends on your account size, your other assets, your charitable intentions, your risk tolerance, and — crucially — your remaining time horizon before required distributions arrive.
Some of these approaches are simple. Some are more complex. Some produce dramatic outcomes for the right family and are inappropriate for the wrong one. Let’s walk through them at a high level.
The Roth conversion ladder.
This is the simplest structural approach. During years when your ordinary income is low — the airlock window we wrote about — you convert portions of your traditional IRA to Roth. You pay income tax at the lower current rate rather than the higher future rate. The Roth then grows tax-free, doesn’t generate RMDs during your lifetime, and passes to heirs tax-free.
For households with modest retirement balances — roughly $1M to $2M — a well-designed Roth conversion ladder over 5 to 10 years can address the majority of the tax-trap exposure. This is the strategy the Wall Street Journal writes about when they write about Roth conversions.
The limit of this approach for larger accounts is arithmetic. A $3M IRA compounds at 6% by roughly $180,000 per year. If your annual conversion target is $100,000 or $150,000 to stay in a reasonable tax bracket, you’re barely keeping pace with the growth. The account is a treadmill you can’t quite outrun with basic conversions alone.
Tax-aware partnership funds.
For larger accounts, one architecture combines aggressive Roth conversions with an outside partnership investment that generates ongoing ordinary losses. These losses — flowing through on a K-1 — can offset the ordinary income created by the Roth conversion, dramatically reducing the tax cost of moving money from Traditional to Roth.
The mechanics involve §475 mark-to-market election on the partnership’s trading activities, careful structuring around the Excess Business Loss limitation of §461(l), and eventual basis step-up under §1014 and §754 at death. The strategy typically involves committing $1M to $2M of taxable assets to the partnership investment for a decade or longer.
For qualified purchaser households — net worth of $5M+ excluding primary residence — with $3M+ IRAs and a 10-15 year time horizon before life-expectancy concerns dominate, this architecture can reduce the lifetime family tax burden from the 50-65% default range to something closer to 5-10% of the original account principal. The math is dramatic. The implementation is not simple.
Real estate-based conversion strategies.
A parallel approach places the traditional IRA into a real estate development fund. Because the resulting partnership interest is illiquid and non-controlling, an independent appraisal produces a fair market value materially below the amount invested — the valuation is further compressed during the fund’s early development phase when project uncertainty is highest. The Roth conversion is executed at this appraised valuation, so income tax is paid on a lower amount than the underlying economic commitment. As the fund matures inside the Roth wrapper, the discount unwinds and the assets appreciate tax-free.
The strategy’s effectiveness depends on the specific fund, the appraisal outcome, and the taxpayer’s willingness to accept the illiquidity of the underlying real estate investment. It doesn’t work cleanly for everyone. For accredited investors with 5-year horizons and taxable-side liquidity to cover the conversion tax, it works well.
Charitable strategies.
For families with meaningful charitable intent, there are approaches that satisfy giving goals while simultaneously reducing the family’s tax exposure — often at essentially zero implementation complexity.
Qualified Charitable Distributions (QCDs) allow direct distributions from IRAs to charity, up to $111,000 per individual per year in 2026 (indexed to inflation), satisfying required minimum distributions without triggering income tax on the distributed amount. For a married couple where both spouses are 70½ or older, that’s $222,000 per year that can be moved directly from an IRA to charity without any tax cost. Over a 20-year retirement, this can move $4M+ of otherwise-taxable RMDs to charity.
Charitable bequests of IRA assets at death direct entire accounts (or portions) to charity, entirely avoiding both income tax and estate tax on the charitable portion. For families who plan to give substantially to charity regardless, structuring those gifts as IRA bequests is dramatically more efficient than giving from taxable accounts.
QCDs became more valuable under OBBBA specifically. Starting in 2026, itemized charitable deductions are subject to a 0.5% AGI floor and, for top-bracket taxpayers, a cap that reduces the deduction’s benefit from 37 cents on the dollar to 35 cents. QCDs bypass both limits because they’re an exclusion from income rather than a deduction. For high-income households with charitable intent, QCDs are strictly better than making the same donations from taxable accounts.
These strategies aren’t appropriate for families without charitable intent. But for those who have it, they can address a large share of the tax-trap problem with essentially no implementation complexity.
Residency and timing.
For families able to relocate, moving to a no-income-tax state before executing large Roth conversions can save the state-tax portion of the conversion cost. For a $3M conversion in a 5% state, that’s $150,000 of savings. Not trivial.
Similarly, timing Roth conversions to coincide with unusually low-income years — early retirement before Social Security starts, years with large business losses, sabbatical years — can significantly reduce the marginal rate on conversion income.
These aren’t structural strategies the way the partnership and real estate approaches are. But they’re free money for families whose circumstances allow them, and they should be layered onto any other approach.
Which one fits?
The honest answer depends on specifics that no blog post can address. The general shape:
For households with $1M to $3M in traditional IRAs and no meaningful taxable-side assets beyond that, some combination of aggressive Roth conversion sequencing, QCDs (if charitable), and residency planning is usually sufficient. The tax-trap can be addressed at the modest end without complex structures.
For households with $3M+ in traditional IRAs and $5M+ in total investable assets, the partnership or real estate architectures become economically compelling. The larger the account, the more dramatic the differential between default and engineered outcomes.
For households with substantial charitable intent regardless of tax planning, the QCD and charitable-bequest strategies typically capture most of the available benefit at lower complexity — and adding the partnership or real estate layer often isn’t worth it.
For families in late-stage life with shortened time horizons, none of the multi-year strategies work cleanly. The remaining moves are timing (harvest low-income years for conversions), QCDs, and estate planning for the surviving spouse rather than the household.
Every household falls somewhere on this map. Finding the right combination is a specific analytical exercise — the kind of exercise we do for each household we work with, using a modeling framework we’ve built around the full lifetime family tax picture.
We’ve written a working analytical memo on the full architecture — including the mechanics of each approach and worked client examples for households at different balance sizes. If you’d like to see it, request the memo.
The problem is real. The solutions are real. Which one is right for you depends on you.
