Roth conversions are frequently presented as a simple retirement tax strategy: pay taxes now, move money into a Roth IRA, and enjoy tax-free withdrawals later.

But that explanation overlooks one of the most important questions you should answer before converting anything:

Who is the Roth conversion really intended to benefit?

Is it designed to reduce your taxes during retirement? Protect your spouse after your death? Preserve more of your retirement savings for your children? Or support a charitable organization?

The right strategy can look very different depending on your answer.

The Widow’s Tax Trap

When one spouse dies, the surviving spouse may experience what Leibel Sternbach describes as a retirement tax “triple whammy.”

First, the surviving spouse typically loses one Social Security benefit. Although the household’s income declines, many of its expenses remain largely unchanged.

Second, the surviving spouse eventually begins filing taxes as a single taxpayer. Single tax brackets are narrower than married filing jointly brackets, which means the surviving spouse may reach higher tax rates with less income.

Third, required minimum distributions, or RMDs, do not automatically decline simply because one spouse has died. The surviving spouse may still need to withdraw substantial amounts from retirement accounts while now paying taxes under less favorable single tax brackets.

The result can be less household income combined with a higher proportional tax burden.

A properly planned Roth conversion may reduce the amount held in tax-deferred retirement accounts before one spouse dies. This can lower future RMDs and provide the surviving spouse with access to tax-free Roth assets.

The SECURE Act Changed Inherited IRAs

Roth conversion planning can also have a major effect on your children.

Before the SECURE Act, many beneficiaries could stretch distributions from an inherited IRA over their life expectancy. That allowed the account to remain tax-deferred for decades.

For most non-spouse beneficiaries, that opportunity is gone.

Many beneficiaries must now empty an inherited retirement account within 10 years. Depending on the beneficiary and the account circumstances, distributions may also be required during that period.

This can create a significant tax problem. Adult children often inherit retirement accounts while they are in their peak earning years. Adding inherited IRA withdrawals to an already high income could push them into an even higher tax bracket.

Instead of inheriting the full economic value of the account, they may lose a substantial portion to federal and state taxes.

By converting some retirement assets at a lower tax rate during your lifetime, you may be able to leave your beneficiaries Roth assets that can generally be withdrawn tax-free, assuming applicable requirements are met.

Will a Roth Conversion Pay Off During Your Lifetime?

Not every Roth conversion produces an immediate benefit.

Your age, investment strategy, expected rate of return, current tax bracket, future RMDs, and source of the money used to pay the conversion tax all matter.

For a conservative investor earning moderate returns, it may take 15 to 20 years for the tax-free growth to offset the upfront conversion cost. A younger or more growth-oriented investor may reach that break-even point sooner.

For someone in their seventies or eighties, the largest benefit may not be realized during their own lifetime. The conversion may instead be designed to protect a surviving spouse or reduce the tax burden placed on the next generation.

Do Not Convert Without a Clear Objective

Executing a Roth conversion is relatively easy. Determining how much to convert, when to convert, and which tax bracket to target is much more complicated.

You also need to be cautious about financial products promising that a bonus will “pay the taxes” on your conversion. Annuities and other strategies may be appropriate in certain situations, but the bonuses, restrictions, surrender periods, income provisions, and long-term tradeoffs should be carefully evaluated.

A Roth conversion should not be based on a sales pitch or a general rule of thumb. It should be part of a coordinated retirement, tax, investment, and estate-planning strategy.

Before making your decision, determine whose money you are planning for—and who you ultimately want to benefit.
