A couple in their 60s with substantial retirement income is questioning whether Roth conversions still make sense for their estate plan. They receive $345,000 annually from pensions and hold $1 million in 403(b) accounts. Their primary goal is leaving tax-free assets to their children.
Roth conversions involve moving funds from traditional pre-tax retirement accounts into after-tax Roth accounts. The account holder pays income tax on the converted amount at the time of the transfer. Once in a Roth, the money grows tax-free and distributions are not taxed.
The couple’s high pension income places them in a top tax bracket. Converting $1 million would trigger a significant tax bill, likely pushing them into the highest marginal rates. This financial reality makes the strategy less straightforward than it appears.
Tax law does not impose an age limit for conversions. Retirees of any age can execute them, provided they have sufficient cash outside retirement accounts to pay the taxes. However, using retirement funds to cover the tax bill defeats the purpose of the conversion.
The couple should weigh the tax cost today against the tax savings for heirs. A $1 million conversion could cost over $370,000 in federal taxes alone, depending on their filing status and state. That money is gone permanently and reduces the total estate value.
An alternative approach involves partial conversions spread across multiple years. This strategy can smooth the tax burden and avoid a single-year spike. The couple could convert smaller amounts annually, staying within a lower bracket, though their pension income limits this maneuver.
Required minimum distributions, or RMDs, begin at age 73 for most retirees. The couple must take these mandatory withdrawals from traditional accounts, which will further increase their taxable income. Roth accounts carry no RMD requirement, which is a key benefit for legacy planning.
Heirs who inherit traditional retirement accounts face income tax on withdrawals, often at their own marginal rates. Inherited Roth accounts distribute free of federal tax, provided the original owner held the account for at least five years. This distinction underpins the couple’s stated motivation.
Charitable giving offers another avenue for reducing taxable assets. Qualified charitable distributions from traditional IRAs allow retirees to donate directly to nonprofits without recognizing the withdrawal as income. This strategy does not apply to 403(b) plans, which require a rollover to an IRA first.
The decision hinges on the couple’s cash reserves and overall estate objectives. If they hold substantial liquid assets, paying taxes out of pocket makes conversions feasible. Without that liquidity, the strategy may erode their financial security in retirement.
Financial advisors often recommend running projections that account for future tax rate changes and healthcare costs. The couple should also consider state inheritance taxes, which vary significantly across jurisdictions. A professional analysis can clarify whether the tax-free benefit for heirs outweighs the upfront cost.
The couple’s high income creates a unique planning environment. Most retirees face lower effective rates in retirement, but their pension income inverts that expectation. This position demands careful modeling rather than rule-of-thumb advice.
Roth conversions remain legal and available for those in their 60s. Timing is not an inherent barrier, but the tax mechanics in this income bracket present real challenges. The couple must decide whether they are optimizing for tax efficiency or dollar-weighted inheritance.
