Whether a retired individual can continue funding an Individual Retirement Account hinges on a single, often misunderstood requirement: the presence of earned income. Retirement status alone is irrelevant under federal tax law. The Internal Revenue Code bases IRA contribution eligibility on income type, not employment label or age.
The earned income rule is the controlling test
Earned income, formally called compensation, refers to pay received for active work. This includes wages, salaries, tips, commissions, and net earnings from self-employment after business deductions. As long as earned income exists during the tax year, IRA contributions remain potentially allowable, even if the individual considers themselves fully retired.
The amount of earned income also caps the contribution. An individual cannot contribute more to an IRA than the amount of earned income received for that year. For example, $4,000 of qualifying earned income limits total IRA contributions to $4,000, regardless of statutory maximums.
Income sources that do not qualify as earned income
Several common retirement income streams do not satisfy the earned income requirement. Social Security benefits, pension payments, annuity distributions, required minimum distributions, interest, dividends, and capital gains are all classified as unearned income. These sources, even when substantial, do not permit IRA funding on their own.
Rental income is generally unearned unless it rises to the level of a trade or business with material participation under IRS rules, which is uncommon for most retirees. Alimony counts as earned income only if it stems from divorce agreements executed before 2019, reflecting changes made by the Tax Cuts and Jobs Act.
Part-time work and self-employment change the analysis
Many retirees reenter the workforce on a limited basis, and this income can reopen IRA eligibility. Part-time wages, consulting fees, and freelance income all qualify as earned income. Net self-employment income, after allowable expenses and self-employment tax adjustments, is the relevant measure for IRA purposes.
This creates planning complexity because income may fluctuate year to year. A retiree with sporadic earned income must reassess IRA eligibility annually, as the rule is applied separately to each tax year.
Traditional versus Roth IRA eligibility in retirement
Both Traditional and Roth IRAs require earned income to contribute, but they diverge in other respects. Traditional IRA contributions may be tax-deductible, depending on income level and workplace plan coverage, while Roth IRA contributions are always made with after-tax dollars. Roth IRAs also impose income phaseouts that can restrict eligibility even when earned income exists.
Importantly, there is no longer an age cap for Traditional IRA contributions. The SECURE Act eliminated the age 70½ limit starting in 2020, aligning Traditional IRA rules more closely with Roth IRAs, which never had an age restriction.
Contribution limits apply regardless of retirement status
For 2024 and 2025, the annual IRA contribution limit is $7,000, with an additional $1,000 catch-up contribution allowed for individuals age 50 or older. These limits apply across all IRAs combined, not per account. Earned income must meet or exceed the amount contributed, even when catch-up contributions are used.
The absence of earned income nullifies these limits entirely. Without qualifying compensation, the allowable contribution is zero, regardless of age, account type, or account balance.
Common misconceptions that create costly errors
A frequent misunderstanding is that being “retired” automatically disqualifies someone from IRA contributions. Another is assuming that Social Security or pension income substitutes for wages in satisfying the earned income rule. Both assumptions are incorrect and often lead to excess contributions and IRS penalties.
Understanding that IRA eligibility is transactional rather than status-based is critical. The tax code asks not whether someone is retired, but whether qualifying compensation exists during the year in question.
The End of Age Limits: How the SECURE Act Changed IRA Contribution Rules for Retirees
The prior discussion establishes that earned income, not retirement status, governs IRA eligibility. The SECURE Act of 2019 reinforced this principle by removing an arbitrary age-based restriction that had long complicated retirement planning. Understanding what changed—and what did not—clarifies when a retired individual may still contribute to an IRA.
The pre-SECURE Act age restriction
Before 2020, Traditional IRA contributions were prohibited once an individual reached age 70½. This restriction applied regardless of whether the person continued working or had substantial earned income. Roth IRAs, by contrast, never imposed an age limit, creating an inconsistency between the two account types.
This rule often penalized retirees who worked part-time, consulted, or delayed full retirement. Even modest wages could not be sheltered in a Traditional IRA solely because of age.
What the SECURE Act eliminated—and what it preserved
The SECURE Act removed the age 70½ contribution cap for Traditional IRAs beginning with the 2020 tax year. As a result, there is now no maximum age for contributing to either a Traditional or Roth IRA. Eligibility instead depends entirely on the presence of qualifying compensation, defined as taxable wages, salaries, tips, or net self-employment income.
Crucially, the law did not alter the earned income requirement itself. Age no longer disqualifies a retiree, but the absence of earned income still does.
Practical implications for working retirees
A retiree who earns income through part-time employment, consulting, or self-employment may contribute to an IRA at any age, subject to annual contribution limits. This applies even if the individual is also receiving Social Security benefits, pension payments, or required minimum distributions (RMDs), which are mandatory withdrawals from certain retirement accounts starting at a specified age.
However, Social Security benefits, pensions, annuities, and investment income do not count as earned income. These income sources do not create IRA eligibility on their own, even after the age restriction was eliminated.
Traditional versus Roth considerations after the age cap removal
The removal of the age limit primarily affected Traditional IRAs, bringing their contribution rules closer to those of Roth IRAs. A key distinction remains in tax treatment. Traditional IRA contributions may be deductible, depending on income and workplace retirement plan coverage, while Roth IRA contributions are never deductible but allow for tax-free qualified withdrawals.
Roth IRAs also retain income-based phaseouts that can restrict eligibility for higher-income retirees with earned income. The SECURE Act did not modify these phaseouts, making income level—not age—the primary limiting factor for Roth contributions.
Spousal income and continued eligibility
The age limit removal also interacts with the spousal IRA rule. A spousal IRA allows a nonworking or lower-earning spouse to contribute based on the working spouse’s earned income, provided the couple files a joint tax return. Age does not restrict this strategy, but sufficient combined earned income is still required to support the contributions.
This remains one of the few ways a fully retired individual without personal earnings may legally fund an IRA, emphasizing that income source, not account ownership, controls eligibility.
Why misconceptions persist after the SECURE Act
Many retirees incorrectly assume that the elimination of the age cap means IRA contributions are automatically permitted in retirement. Others believe that receiving Social Security or pension income satisfies the new rules. These misunderstandings stem from conflating age eligibility with income eligibility.
The SECURE Act removed a barrier, not a condition. Retirees can contribute to an IRA later in life, but only when earned income exists in the same tax year and all other eligibility requirements are met.
Traditional IRA vs. Roth IRA After Retirement: Contribution Eligibility and Tax Trade-Offs
With the age restriction removed, the practical question for retirees shifts from whether contributions are allowed to which type of IRA remains accessible and tax-efficient. Traditional and Roth IRAs now share similar age-based eligibility, but they continue to differ materially in income requirements, tax treatment, and long-term consequences. Understanding these distinctions is essential for retirees who still generate earned income.
Earned income remains the gateway for both IRA types
Both Traditional and Roth IRAs require earned income to support a contribution. Earned income generally includes wages, salaries, tips, bonuses, and net income from self-employment. It does not include Social Security benefits, pension payments, annuities, investment income, or required minimum distributions.
For a retired individual, this means eligibility may arise from part-time employment, consulting work, or operating a small business. The amount contributed cannot exceed the amount of earned income for the year, regardless of account type.
Traditional IRA contributions after retirement
Traditional IRAs no longer impose an upper age limit on contributions, provided earned income exists in the same tax year. Contributions may be deductible, meaning they reduce taxable income, but deductibility depends on modified adjusted gross income and whether the individual or spouse is covered by a workplace retirement plan.
For retirees, this distinction is critical. A retired person with earned income but no active employer plan may still qualify for a fully deductible contribution, while one covered by post-retirement employment benefits may face partial or complete phaseouts. Even when contributions are nondeductible, the account remains tax-deferred, with taxes owed upon withdrawal.
Roth IRA contributions and income phaseouts
Roth IRAs have never had an age cap, and the SECURE Act did not change their contribution rules. However, Roth eligibility is constrained by income-based phaseouts tied to modified adjusted gross income. Retirees with earned income that exceeds these thresholds are prohibited from contributing directly, regardless of age.
Unlike Traditional IRAs, Roth contributions are made with after-tax dollars and are never deductible. The trade-off is that qualified withdrawals, including investment earnings, are tax-free if holding period and age requirements are satisfied. This tax structure can be attractive to retirees managing future tax exposure, but eligibility hinges entirely on income levels.
Contribution limits and catch-up amounts
The annual IRA contribution limit applies across all IRA accounts combined. Under current law, individuals may contribute up to $7,000 per year, with an additional $1,000 catch-up contribution for those age 50 or older. These limits apply equally to Traditional and Roth IRAs and do not increase simply because a person is retired.
Earned income sets an absolute ceiling. A retiree earning $4,000 from part-time work, for example, cannot contribute more than $4,000 in total IRA contributions for that year.
Tax timing, required distributions, and planning implications
Traditional and Roth IRAs diverge most sharply in how and when taxes are paid. Traditional IRAs generally produce taxable withdrawals and are subject to required minimum distributions, which mandate annual withdrawals beginning at a specified age. Roth IRAs have no required minimum distributions during the original owner’s lifetime.
For retirees with earned income, the choice between account types affects current tax liability, future taxable income, and interactions with other retirement income sources. These tax mechanics do not alter eligibility, but they significantly influence how post-retirement contributions integrate into an overall retirement income framework.
What Counts as “Earned Income” — and What Does Not — for Retired Individuals
Whether a retired individual can continue contributing to an IRA depends entirely on the presence of earned income. The Internal Revenue Code uses a narrow definition, and many common retirement income sources do not qualify. Understanding this distinction is essential because earned income establishes both eligibility and the maximum contribution amount.
Definition of earned income for IRA purposes
Earned income is compensation received for personal services actually performed. This includes wages, salaries, tips, bonuses, and commissions reported on a Form W-2. It also includes net earnings from self-employment, which are calculated after deducting ordinary and necessary business expenses.
For self-employed retirees, earned income is not gross revenue but net profit subject to self-employment tax. This distinction is critical, as business deductions directly reduce the amount eligible for IRA contributions. If net earnings are zero or negative, no IRA contribution is permitted for that year.
Common income sources that do not qualify as earned income
Most retirement income streams are explicitly excluded from the earned income definition. Social Security retirement benefits, regardless of whether they are partially taxable, do not count as earned income. Pension payments, annuity income, and distributions from Traditional or Roth IRAs are also excluded.
Investment-related income does not qualify. Interest, dividends, capital gains, rental income, and distributions from taxable brokerage accounts are considered unearned income and cannot support IRA contributions. Required minimum distributions are similarly excluded, even though they are taxable.
Part-time work and phased retirement arrangements
Many retirees engage in part-time employment or consulting work, often referred to as phased retirement. Compensation from these activities generally qualifies as earned income, provided the work involves active personal services. Even modest earnings can allow continued IRA contributions, subject to annual contribution limits.
However, earned income also sets an upper boundary. If a retiree earns $3,500 from part-time wages, total IRA contributions for that year cannot exceed $3,500, regardless of age or account type. This cap applies across all Traditional and Roth IRAs combined.
Self-employment and gig income in retirement
Income from independent contracting, freelancing, or gig-based work may qualify as earned income, but only after accounting for expenses. Retirees must carefully distinguish between gross receipts and net earnings when determining contribution eligibility. Overstating earned income can result in excess contributions and potential penalties.
Additionally, self-employed individuals must consider the interaction between self-employment tax and IRA contributions. While contributions may reduce taxable income in certain cases, they do not eliminate self-employment tax exposure.
Special situations and frequent misconceptions
Certain payments are commonly misunderstood as earned income but do not qualify. Severance pay received after retirement generally does not count unless tied to ongoing services. Unemployment compensation, workers’ compensation, and disability payments are also excluded.
Alimony qualifies as earned income only if it arises from divorce or separation agreements finalized before 2019. Agreements executed after that date produce alimony that is neither taxable nor treated as earned income for IRA purposes. These nuanced rules often determine whether a retired individual remains eligible to fund an IRA in a given year.
Common Retirement Income Sources and IRA Funding Myths (Social Security, Pensions, Annuities)
As retirees transition away from wages, the composition of their income often changes dramatically. This shift gives rise to persistent confusion about whether common retirement income streams allow continued IRA contributions. The key distinction is not whether income is taxable, but whether it meets the IRS definition of earned income.
Social Security benefits
Social Security retirement benefits are among the most frequently misunderstood income sources in this context. Even though up to 85 percent of Social Security benefits may be taxable at higher income levels, these payments are not considered earned income. They are classified as replacement income based on prior work history, not compensation for current services.
As a result, Social Security benefits alone never permit IRA contributions. A fully retired individual receiving only Social Security, regardless of benefit size or taxability, is ineligible to fund either a Traditional or Roth IRA. This rule applies uniformly and has no exceptions tied to age or benefit type.
Pension income and employer-sponsored retirement payments
Defined benefit pensions and similar employer-sponsored retirement payments also fail the earned income test. These distributions represent deferred compensation earned in prior years rather than payment for current labor. Their predictable nature and frequent tax withholding often lead retirees to assume they function like wages, but this assumption is incorrect for IRA purposes.
Even when pension income is fully taxable, it does not create IRA contribution eligibility. The same treatment applies to military pensions, civil service retirement payments, and most private-sector pension plans. Taxability and earned income status are governed by entirely separate rules.
Annuity payments and lifetime income streams
Annuities, whether purchased individually or through an employer plan, present another common source of confusion. Periodic annuity payments typically consist of a taxable earnings portion and a non-taxable return of principal. Neither portion is treated as earned income under IRS rules.
This distinction holds regardless of whether the annuity is immediate or deferred, fixed or variable. Once annuity payments begin, they are categorized as investment income, not compensation. Consequently, annuity income cannot support IRA contributions in retirement.
Why taxability does not equal IRA eligibility
A recurring misconception is that any income reported on a tax return qualifies for IRA funding. In reality, the IRS draws a sharp line between earned income and unearned income. Earned income arises from active work, while retirement income sources generally reflect past employment or invested capital.
This distinction explains why wages from part-time or self-employment activity can enable IRA contributions, while larger amounts from Social Security, pensions, or annuities cannot. Understanding this framework is essential for retirees evaluating whether continued IRA funding is permissible in a given year.
Interaction with Traditional and Roth IRAs
The earned income requirement applies equally to Traditional and Roth IRAs. The elimination of age-based contribution limits allows retirees of any age to contribute, but only if they have sufficient earned income. The annual contribution limit applies across all IRAs combined and is capped by the amount of qualifying earnings.
For Roth IRAs, additional income phaseouts based on modified adjusted gross income may further restrict eligibility. However, these phaseouts operate independently of the earned income requirement. Without earned income, neither account type can be funded, regardless of overall wealth or retirement income levels.
Using Part-Time Work, Consulting, or Self-Employment to Keep Contributing to an IRA
For retirees seeking to continue IRA contributions, part-time employment, consulting, or self-employment represents the most common and clearly permitted pathway. As established earlier, the IRS requires earned income, defined as compensation from active work, to support any IRA contribution. Even modest levels of qualifying earnings can preserve eligibility, provided all other IRA rules are satisfied.
This principle applies regardless of retirement status. A person may be fully retired from a primary career yet still generate earned income through limited work activity that meets IRS definitions.
What types of work qualify as earned income
Wages paid by an employer and reported on Form W-2 constitute earned income for IRA purposes. This includes part-time jobs, seasonal employment, and temporary work arrangements. The number of hours worked is irrelevant; only the presence of taxable compensation matters.
Self-employment income also qualifies when it reflects active business activity. Consulting, freelancing, gig work, and sole proprietorship income generally meet the earned income requirement, provided the activity is conducted with a profit motive and reported appropriately for tax purposes.
How self-employment income is measured for IRA eligibility
For self-employed individuals, earned income is not gross revenue but net earnings from self-employment. Net earnings generally equal business income after deducting ordinary and necessary business expenses, as reported on Schedule C, and after accounting for certain self-employment tax adjustments.
This distinction is critical because IRA contribution limits are capped by the amount of qualifying net earnings. High gross receipts do not automatically translate into high IRA eligibility if expenses substantially reduce net income.
Contribution limits and the absence of age restrictions
The elimination of age-based contribution caps allows individuals of any age to fund an IRA, provided earned income exists. The annual contribution limit is set by the IRS and applies across all Traditional and Roth IRAs combined. For 2024 and 2025, the limit is $7,000, or $8,000 for individuals age 50 or older, subject to future inflation adjustments.
Contributions cannot exceed earned income for the year. If part-time or self-employment income totals less than the annual limit, the contribution is restricted to that lower amount.
Differences between Traditional and Roth IRAs for working retirees
Both Traditional and Roth IRAs require earned income, but they differ in how contributions are taxed. Traditional IRA contributions may be deductible depending on income levels and participation in other retirement plans, while Roth IRA contributions are made with after-tax dollars.
Roth IRAs impose additional eligibility limits based on modified adjusted gross income (MAGI). A retiree with earned income may still be barred from Roth contributions if total income exceeds IRS phaseout thresholds, even though the earned income requirement itself is satisfied.
Common misconceptions about “working in retirement”
A frequent misunderstanding is that informal or sporadic work does not count for IRA purposes. In reality, even limited paid activity qualifies if it produces taxable earned income and is properly reported.
Another misconception is that investment income, pension payments, or Social Security benefits can be combined with wages to increase IRA eligibility. Only earned income counts toward the contribution cap; retirement and investment income remain excluded regardless of amount.
Timing and reporting considerations
IRA contributions for a given tax year may be made up until the federal tax filing deadline, typically April 15 of the following year, excluding extensions. Earned income must relate to the same tax year as the contribution.
Accurate income reporting is essential, particularly for self-employed retirees. IRS scrutiny focuses on whether income reflects genuine compensation for services, reinforcing the importance of proper documentation and tax compliance when using post-retirement work to support IRA funding.
Annual IRA Contribution Limits, Spousal IRAs, and Coordination Between Retired Couples
Understanding contribution limits and household-level coordination becomes increasingly important when only one spouse has earned income or when both spouses are partially retired. While the rules governing IRAs apply on an individual basis, married couples often have planning flexibility that single retirees do not.
Annual IRA contribution limits and the role of earned income
The IRS sets an annual maximum IRA contribution limit that applies per individual, not per household. For 2025, the limit is $7,000 per person, with an additional $1,000 catch-up contribution permitted for individuals age 50 or older, subject to future inflation adjustments.
The critical constraint is earned income, defined as taxable compensation such as wages or net self-employment income. A retired individual may contribute up to the annual limit only if earned income equals or exceeds that amount for the year; otherwise, the contribution is capped at actual earned income.
These limits apply separately to each spouse. One spouse’s earned income generally cannot be used to justify a contribution to the other spouse’s IRA unless specific spousal IRA rules are met.
Spousal IRAs when only one spouse has earned income
A spousal IRA allows a married couple filing a joint tax return to fund an IRA for a non-working or low-earning spouse using the working spouse’s earned income. This provision is especially relevant when one spouse is fully retired while the other continues to work part time or remains self-employed.
To qualify, the couple must file jointly, and combined earned income must be sufficient to cover the total contributions made to both spouses’ IRAs. Each spouse must maintain a separate IRA account in their own name, even though the earned income source is shared.
Spousal IRAs are not a distinct account type under tax law. Either a Traditional IRA or a Roth IRA may be used, subject to the same deductibility rules, income phaseouts, and contribution limits that apply to any other IRA.
Traditional versus Roth IRA considerations within retired households
When coordinating contributions between spouses, the choice between Traditional and Roth IRAs has tax implications at both the individual and household level. Traditional IRA contributions may be deductible, reducing current taxable income, but distributions are generally taxable in retirement.
Roth IRA contributions are made with after-tax dollars and do not provide an upfront deduction. However, qualified withdrawals are tax-free, and Roth IRAs are not subject to required minimum distributions during the original owner’s lifetime.
Income-based eligibility rules complicate this coordination. A retired couple may have sufficient earned income for contributions but still be ineligible for Roth contributions due to modified adjusted gross income exceeding IRS thresholds, particularly when Social Security benefits, pensions, and portfolio income are layered together.
Coordinating contributions between retired spouses
Effective coordination requires evaluating each spouse’s earned income, age, and IRA eligibility independently while also considering the household’s overall tax position. In some cases, directing contributions to one spouse’s IRA may be feasible while the other spouse remains ineligible due to income limitations or lack of earned income.
Catch-up contributions further differentiate planning between spouses of different ages. A spouse age 50 or older may contribute more than a younger spouse, provided earned income supports the higher amount.
Care must also be taken to avoid excess contributions, which trigger IRS penalties if contributions exceed allowable limits based on income or eligibility. This risk increases in retirement years when income sources fluctuate and earned income is less predictable.
Common coordination pitfalls for retired couples
One frequent error is assuming that pension payments, Social Security benefits, or required minimum distributions can support IRA contributions for a non-working spouse. These income sources do not qualify as earned income and cannot be used to justify either individual or spousal IRA contributions.
Another pitfall involves uneven income timing, such as self-employment income earned late in the year or business losses that reduce net earnings. Because contribution eligibility depends on final earned income for the tax year, premature contributions may later prove excessive.
Careful tracking of earned income, filing status, and income-based eligibility thresholds is essential when retired couples attempt to continue IRA funding. The rules are precise, and compliance depends on aligning contributions with both individual and household-level tax realities.
Strategic Planning Considerations: When Continuing IRA Contributions Makes — or Does Not Make — Sense
With eligibility rules and coordination challenges clarified, the remaining question is whether continuing IRA contributions in retirement meaningfully advances a retiree’s broader financial and tax objectives. The answer depends on the source and stability of earned income, current and future tax rates, and how additional tax-deferred or tax-free savings interact with required distributions and cash flow needs.
Situations where continued IRA funding can be strategically sound
Continuing IRA contributions often makes sense for retirees who maintain consistent earned income through part-time employment or self-employment. Earned income refers to wages, salaries, tips, or net self-employment income after business expenses, and it remains the foundational requirement for both Traditional and Roth IRA contributions.
For retirees eligible for Roth IRA contributions, ongoing funding may support long-term tax diversification. Roth IRAs grow tax-free and are not subject to required minimum distributions (RMDs), which can reduce future taxable income and improve flexibility in later retirement years.
Traditional IRA contributions may still be relevant when they are deductible. A deductible contribution reduces current taxable income, which can be valuable during years when earned income pushes a retiree into a higher marginal tax bracket due to overlapping income sources such as consulting income or delayed Social Security benefits.
When continued contributions may provide limited benefit
In contrast, continuing IRA contributions may be less effective when earned income is minimal, irregular, or likely to disappear in the near term. Because contributions cannot exceed earned income for the year, retirees with fluctuating or declining earnings face a higher risk of excess contributions and associated IRS penalties.
Non-deductible Traditional IRA contributions often provide limited strategic value for retirees. While investment growth remains tax-deferred, future withdrawals are partially taxable and subject to RMDs, creating administrative complexity without significant tax advantage.
For retirees already subject to RMDs from other retirement accounts, additional Traditional IRA balances may increase future taxable income. This can affect the taxation of Social Security benefits and exposure to higher Medicare premium brackets, formally known as income-related monthly adjustment amounts (IRMAA).
Tax bracket management and timing considerations
The relative tax benefit of continuing IRA contributions depends heavily on current versus expected future tax rates. Retirees in temporarily high tax brackets due to earned income may find Roth contributions less favorable than during lower-income years.
Conversely, retirees in lower tax brackets before RMDs begin may benefit from Roth contributions if eligible, particularly when earned income is modest and predictable. This underscores the importance of evaluating contributions within a multi-year tax framework rather than in isolation.
Contribution timing also matters. Although IRA contributions can be made up to the tax filing deadline for the prior year, eligibility ultimately depends on final earned income. Conservative contribution timing can reduce the risk of corrections when year-end income is uncertain.
Clarifying common misconceptions that drive poor decisions
A frequent misconception is that receiving income of any kind permits IRA contributions. Pension payments, Social Security benefits, annuity income, investment dividends, and RMDs are not earned income and cannot support contributions, regardless of amount.
Another misunderstanding involves age. There is no longer an upper age limit for contributing to a Traditional or Roth IRA, but the removal of the age cap did not relax the earned income requirement. Age alone neither qualifies nor disqualifies a retiree from contributing.
Part-time and self-employment income can qualify, but only net earnings count. Business losses, retirement plan deductions, and self-employment taxes can significantly reduce eligible contribution amounts, sometimes below the maximum annual limit.
Integrating IRA contributions into a broader retirement strategy
IRA contributions should be evaluated alongside RMD obligations, taxable investment income, and anticipated changes in income sources. The objective is alignment, not accumulation for its own sake.
For some retirees, preserving simplicity, reducing future tax reporting, and managing cash flow may outweigh the incremental benefit of continued contributions. For others, especially those with sustained earned income and clear tax objectives, ongoing IRA funding remains a valid planning tool.
Ultimately, continuing IRA contributions in retirement is neither inherently beneficial nor inherently unnecessary. The decision hinges on strict eligibility rules, tax implications, and how additional retirement savings integrate with the retiree’s overall financial structure and long-term income plan.
