How to Navigate the Tax Rules and Timelines of an Inherited Annuity

Inheriting money from a loved one is often a bittersweet milestone, blending the grief of loss with the sudden responsibility of managing a financial windfall. Recently, a reader wrote to MarketWatch seeking guidance after their two sons inherited a $30,000 annuity from their grandmother, expressing confusion over a supposed five-year timeline to withdraw the funds.[1]

This scenario is increasingly common as the massive generational wealth transfer gets underway. Annuities, which are insurance contracts designed to provide a steady income stream during retirement, are frequently passed down to children and grandchildren. But unlike a simple cash inheritance or a stepped-up stock portfolio, inherited annuities come with a labyrinth of strict Internal Revenue Service (IRS) regulations, tight deadlines, and hidden tax traps.[2][3]

To navigate this landscape, beneficiaries must first understand what exactly they have inherited. The Financial Industry Regulatory Authority (FINRA) defines an annuity as a contract between an individual and an insurance company, where the "annuitant" is the person whose life expectancy determines the payout. When the annuitant dies, the remaining value—if a death benefit was selected—passes to the designated beneficiary.[3]

The most critical distinction a beneficiary must make is whether the inherited annuity is "qualified" or "non-qualified." This single factor dictates how the IRS will tax the inheritance. A qualified annuity was funded with pre-tax dollars, typically inside a retirement account like an IRA or 401(k). Because the original owner never paid taxes on that money, the IRS requires the beneficiary to pay ordinary income tax on every single dollar withdrawn.[2][5]

Conversely, a non-qualified annuity was funded with after-tax dollars. For these contracts, the original contributions are returned to the beneficiary tax-free. However, the IRS applies a "last-in, first-out" rule to the earnings, meaning any growth the account experienced is taxed as ordinary income, and those taxable earnings are distributed first before the tax-free principal is touched.[5]

Once the tax status is determined, the clock starts ticking. For decades, beneficiaries could "stretch" the distributions from an inherited IRA annuity over their own life expectancy, minimizing the annual tax hit. But the SECURE Act, passed in 2019, drastically rewrote the rules of wealth transfer.[2][4]

Under the SECURE Act, most non-spouse beneficiaries who inherit a qualified annuity are now subject to the "10-Year Rule." This mandate requires the beneficiary to completely empty the account by December 31 of the year containing the tenth anniversary of the original owner's death. While the funds can be withdrawn at any pace during that decade, leaving the balance untouched until year ten can trigger a massive, concentrated tax bill.[2][4]

The rules shift again for non-qualified annuities, which are generally governed by the "Five-Year Rule." If a beneficiary does not proactively elect a different payout structure, the IRS requires the entire value of the non-qualified annuity to be distributed within five years of the owner's death.[5]

The danger of the five-year rule lies in its default status. Financial experts warn that beneficiaries typically have a narrow window—often just 60 days from the time they notify the insurance company of the death—to make an election. If they miss this window or ignore the paperwork, they are locked into the five-year depletion schedule, potentially losing the ability to spread the tax burden over a longer period.[5]

Special exceptions exist for minor children, adding another layer of complexity to scenarios like the one highlighted by MarketWatch. The IRS recently clarified that if a minor inherits a retirement account directly from a parent, they can take required minimum distributions based on their life expectancy until they reach the age of majority, which the IRS has set at 21 nationwide.[1][2]

Once that child turns 21, the standard 10-year clock begins, requiring full depletion by age 31. However, this parental exception does not apply to grandchildren. If a minor inherits an annuity from a grandparent, as in the MarketWatch example, they are immediately subject to the 10-year rule, regardless of their age.[1][2]

Spouses enjoy the most flexibility under the current tax code. A surviving spouse who is the sole beneficiary can often execute a "spousal continuation," rolling the annuity into their own name and treating the contract as if they had purchased it themselves. This allows them to delay required minimum distributions until their own retirement age, preserving the tax-deferred growth.[4]

For non-spouses, the temptation to take the inheritance as an immediate lump sum is often strong, but it is rarely the most efficient choice. Taking a lump-sum distribution forces the entire taxable portion of the annuity into a single tax year. For a substantial inheritance, this sudden spike in income can push the beneficiary into a higher marginal tax bracket, trigger Medicare surtaxes, and phase out other valuable tax deductions.[5][6]

Instead, financial planners generally advise spreading the withdrawals out over the allowable five- or ten-year windows. By strategically taking distributions in years where their baseline income is lower, beneficiaries can smooth out their tax liability and keep more of the windfall.[6]

Ultimately, an inherited annuity is a powerful financial tool, but it requires proactive management. Beneficiaries must resist the urge to make immediate, irreversible decisions while grieving. By identifying the type of annuity, understanding the applicable IRS timelines, and consulting with tax professionals, heirs can honor their loved one's legacy by maximizing the gift they were left behind.[6]
