U.S. tax law and federal benefit programs are structured around your specific age. A contribution window opens for you at 50 and another at 60. A 10% penalty disappears at 59½. A Medicare clock starts at 65. A required minimum distribution obligation arrives at 73. If you miss a deadline, or misunderstand which rule applies to your birth year, you may lose a benefit or incur an avoidable cost that persists for years.
This reference maps every major age-based milestone, with source links to IRS and SSA guidance. It is organized chronologically and includes several milestones that do not appear on standard planning timelines but carry meaningful consequences for your planning.

Can Your Child Contribute to a Roth IRA? Yes, If They Have Earned Income
The IRS does not impose a minimum age for IRA contributions. Your child of any age may contribute to a Roth IRA as long as they have earned income, meaning wages, tips, or net self-employment income. Your child's annual contribution cannot exceed the lesser of their total earned income or the annual Roth IRA contribution limit in effect for that year.
In practice, you or your guardianship can open a custodial Roth IRA for your child through a brokerage that offers them. The account converts automatically to a standard individual Roth IRA when your child reaches the age of majority under your state's law (typically 18 or 21). Your child's contributions grow federal-income-tax-free, and qualified distributions in retirement are federal-tax-free.
The most common starting point is when your child earns money from a formal job, babysitting, lawn care, or another verifiable source of compensation. Unearned income (investment dividends, interest, gifts, allowances) does not qualify.

Contribution limits are adjusted periodically for inflation. Verify the current limit with the IRS before contributing.
Ages 18-21: Your Legal Adulthood and Custodial Account Transfers
Age 18 is the threshold for most markers of your legal adulthood at the federal level and in most states:
- Opening your individual brokerage accounts without a custodian
- Applying for credit cards in your own name
- Signing binding contracts on your behalf
- Filing your taxes independently (though a parent may still claim you as a dependent in some circumstances)
Your UGMA and UTMA custodial accounts transfer irrevocably to you at the age of majority, which is typically 18 in most states and 21 in others. Once transferred, the assets belong unconditionally to you; the original account owner (typically your parent) no longer controls them. The specific age depends on the state where your account was opened and the type of account (UGMA vs. UTMA), so if you have custodial accounts, you should verify the applicable transfer age rather than assuming it is 18.
Age 21 and your inherited IRAs: Under SECURE 2.0, if you are a minor child who inherits an IRA from a parent (as an eligible designated beneficiary), you may use your own life expectancy to calculate annual distributions until you reach age 21. At 21, your life expectancy method ends and the 10-year rule begins: your entire inherited IRA must be distributed within 10 years of reaching age 21. This rule applies only to minor children of the deceased account owner; other beneficiary categories follow different rules.

At Age 24: Your FAFSA Independence
For federal student aid purposes, you are automatically considered independent at age 24, meaning your parental income and assets are excluded from your Expected Family Contribution calculation on your FAFSA. You can also establish independence before 24 through marriage, graduate enrollment, active military duty, having dependents, or other qualifying conditions. This is a financial aid rule rather than a tax rule, but it affects how you and your family structure your savings and income during the college-funding years.
At Age 26: Your Dependent Health Insurance and ABLE Accounts
Your ACA dependent health coverage ends at 26. Under the Affordable Care Act, group health plans and individual market plans that cover dependents must allow you to remain on your parent's plan until age 26, regardless of your marital, student, or employment status. Your coverage ends on your 26th birthday (or the end of the plan year in some grandfathered plans). A Special Enrollment Period opens when your dependent coverage ends, allowing you to enroll in a marketplace plan outside of the standard open enrollment window.
ABLE accounts and the disability onset threshold for you. ABLE accounts (Achieving a Better Life Experience) are tax-advantaged savings accounts for you if your disability or blindness began before a specified age. Under current law, your disability must have begun before age 26. Under SECURE 2.0 (Section 121), this threshold increases to before age 46, effective January 1, 2026. This change significantly expands ABLE eligibility to a much larger population of working-age adults with disabilities. If you have a disability or are an advisor with clients who may benefit from ABLE accounts, you should revisit eligibility once the 2026 change takes effect.

At Age 30: Your Coverdell Education Savings Account Deadline
Your Coverdell Education Savings Account (ESA) must distribute all remaining funds by the time you reach age 30, unless you have special needs. If your funds are not used by the deadline, they are subject to income tax and a 10% penalty on the earnings portion. To avoid this, you may be able to roll over your balance to a Coverdell ESA for another qualifying family member who is under age 30.
Coverdell ESAs are separate from 529 plans. The Coverdell annual contribution limit is $2,000 and subject to income phaseouts for the contributor; these are not features of standard 529 plans. The 30-year deadline does not apply to 529 accounts.

At Age 50: Your Catch-Up Contributions Begin
At age 50, you become eligible to make catch-up contributions to most of your tax-advantaged retirement accounts. These additional contributions are in addition to your standard annual limits.
The figures below reflect contribution limits for 2026 and are subject to annual adjustment for inflation. Verify current limits with the IRS before contributing.
| Account Type | Standard Limit (2026) | Catch-Up Addition (2026) | Total (2026) |
|---|---|---|---|
| 401(k), 403(b), governmental 457(b) | $24,500 | $8,000 | $32,500 |
| Traditional IRA, Roth IRA | $7,500 | $1,100 | $8,600 |
| SIMPLE IRA | $17,000 | $4,000 | $21,000 |
The IRA catch-up contribution increased to $1,100 for 2026, the first increase since the SECURE 2.0 provision indexed it for inflation beginning in 2024.
New for 2026: Roth catch-up requirement for high earners. Beginning in 2026, participants whose prior-year wages with the plan sponsor exceeded $150,000 must make catch-up contributions on a Roth basis (if the plan offers a Roth feature). This applies to 401(k), 403(b), and governmental 457(b) plans. Participants below the $150,000 wage threshold retain the option to make pre-tax or Roth catch-up contributions as the plan allows.
Note for public safety employees: Under IRC Section 72(t)(2)(B), eligible public safety employees (law enforcement, firefighters, emergency medical technicians) in qualified governmental plans may take penalty-free distributions beginning at age 50 rather than the standard 55, and in some cases may have different catch-up provisions as well. Those in this category should verify applicable rules with their plan administrator.

Age 55: HSA Catch-Up and the Rule of 55
HSA Catch-Up Contributions
Account holders who are 55 or older and are enrolled in a qualifying high-deductible health plan (HDHP) may contribute an additional $1,000 per year to their Health Savings Account. This catch-up is in addition to the standard HSA contribution limit (which for 2026 is $4,400 for self-only coverage and $8,750 for family coverage, subject to annual adjustment).
The HSA catch-up eligibility ends when the account holder enrolls in any part of Medicare. Enrollment in Medicare Part A, even if Part B is deferred, ends HSA contribution eligibility. This creates an important planning consideration at age 65 (and before, if Medicare is enrolled in earlier due to disability).
Source: IRS Publication 969: Health Savings Accounts and Other Tax-Favored Health Plans
Contribution limits are adjusted annually; verify current amounts with the IRS.
The Rule of 55
Taxpayers who separate from service from an employer in or after the calendar year in which they turn 55 may take distributions from that employer's 401(k) or 403(b) plan without incurring the 10% early withdrawal penalty under IRC Section 72(t)(2)(A)(v).
Important boundaries:
- Applies to distributions from the plan of the employer from which the individual separated at 55 or older
- Does NOT apply to IRAs
- Does NOT apply to previous employer plans that were not rolled into the current employer's plan before separation
- The separation must occur in or after the calendar year of the 55th birthday (not the actual day of turning 55)
- A 57-year-old who separated from service at 54 does not qualify under the Rule of 55
The Rule of 55 may provide meaningful flexibility for early retirees who need bridge income between leaving employment and reaching age 59½, when the broader penalty exception takes effect.
Source: IRS: Retirement Topics, Exceptions to Tax on Early Distributions
Age 59½: Penalty-Free Withdrawals from Most Accounts
At age 59½, the 10% early withdrawal penalty no longer applies to distributions from:
- Traditional IRAs and Roth IRAs (though Roth earnings withdrawals have separate 5-year rules)
- 401(k), 403(b), and governmental 457(b) plans
- Non-qualified annuities
- SIMPLE IRAs (if the 2-year participation rule has been met)
This is the broadest penalty exception in the tax code for retirement accounts. Unlike the Rule of 55, it applies regardless of employment status and covers IRAs as well as employer plans.
Roth IRA note: While the 10% penalty disappears at 59½, tax-free treatment of earnings also requires the account to have been open for at least 5 years from the date of the first Roth IRA contribution (the "5-year rule"). A person who opens their first Roth IRA at age 57 and reaches 59½ at 59½ would not yet meet the 5-year requirement; earnings withdrawn before the 5-year clock completes may be subject to income tax even if no penalty applies. Contributions (not earnings) can always be withdrawn tax-free and penalty-free at any time.

Ages 60-63: SECURE 2.0 Super Catch-Up Contributions
Beginning January 1, 2025, SECURE 2.0 introduced an enhanced catch-up contribution for participants who are ages 60, 61, 62, or 63 in workplace retirement plans. This "super catch-up" replaces the standard catch-up for those in this age window.
| Account Type | Standard Catch-Up (50+, 2026) | Super Catch-Up (60-63, 2026) |
|---|---|---|
| 401(k), 403(b), governmental 457(b) | $8,000 | $11,250 |
| SIMPLE IRA | $4,000 | $5,250 |
The super catch-up amount is defined as the greater of $10,000 or 150% of the standard catch-up limit, indexed for inflation. For 2026, the limit is $11,250 for 401(k)/403(b)/457(b) plans.
- This does NOT apply to IRAs (IRA catch-up is $1,100 for 2026)
- This does NOT apply to SEP-IRAs
- It does apply to SIMPLE IRAs at a separately calculated amount
- Eligibility ends at the start of the year in which the participant turns 64

Contribution limits reflect 2026 amounts; the IRS adjusts these annually for inflation.
Age 60: Social Security Survivor Benefits
A widow or widower may begin receiving Social Security survivor benefits as early as age 60. Benefits claimed at 60 are permanently reduced relative to the survivor's Full Retirement Age benefit (to approximately 71.5% of the deceased worker's benefit). Disabled widows and widowers may begin survivor benefits at age 50.
Taking survivor benefits at 60 does not prevent the survivor from switching to their own retirement benefit at a later age if their own benefit would be larger. In some cases, a coordinated claiming strategy (claiming survivor benefits early and switching to one's own delayed retirement benefit at 70) may produce a higher lifetime payout, depending on circumstances.
Source: SSA: Survivors Benefits
Age 62: Earliest Social Security Retirement and Spousal Benefits
Age 62 is the earliest age at which most workers may claim Social Security retirement benefits. Benefits claimed at 62 are permanently reduced: for someone with a Full Retirement Age of 67, the age-62 benefit is approximately 70% of the FRA benefit (a 30% permanent reduction). The exact reduction depends on the number of months before FRA that benefits begin.
Spousal benefits are also first available at age 62. A current spouse may receive up to 50% of the other spouse's FRA benefit; the spousal benefit is also reduced if claimed before the claiming spouse's own FRA. A divorced spouse may claim spousal benefits at 62 if the marriage lasted at least 10 years and they have not remarried.
Factors that may affect whether claiming at 62 makes sense for a given individual include current health, longevity expectations, other income sources, the presence of a spouse with a significantly different benefit amount, and whether continued earnings would reduce benefits under the Social Security earnings test (which applies before FRA).
Source: SSA: Retirement Benefits
Age 63: The IRMAA Two-Year Lookback
Medicare's Income-Related Monthly Adjustment Amount (IRMAA) uses federal tax return data from two years prior to set Medicare Part B and Part D premium surcharges. For someone who enrolls in Medicare at age 65, the initial IRMAA determination is based on the tax return from age 63 (income two years before Medicare enrollment).
Income in the year a person turns 63 is the last calendar year that directly sets their initial Medicare IRMAA tier. Events that increase Modified Adjusted Gross Income in that year (a large Roth conversion, an asset sale, an unusually large distribution, or a business income spike) may increase Medicare premiums in the year of Medicare enrollment and the year after.
This connection between income at 63 and Medicare costs at 65 is one of the most commonly overlooked planning interactions in the pre-retirement years.
Source: SSA: Medicare Benefits and IRMAA
For additional detail on the two-year lookback and its interaction with Roth conversions and RMDs, see the IRMAA deep dive on this site.
Age 64: Final Year of ACA Marketplace Coverage
For most people, age 65 triggers Medicare enrollment and the end of Affordable Care Act marketplace coverage. Age 64 is therefore the last full year in which marketplace subsidies (the Advance Premium Tax Credit, or APTC) may apply. Depending on income, this year may carry the highest potential subsidy eligibility, particularly for those who have retired early and have moderate income relative to the ACA subsidy thresholds.
Individuals who plan to enroll in Medicare at 65 should coordinate the end of ACA coverage with the beginning of Medicare enrollment to avoid a coverage gap. The Medicare Initial Enrollment Period spans the seven months centered on the month of the 65th birthday.
Age 65: Medicare Enrollment and HSA Contribution Stop
Medicare eligibility begins at 65. The Initial Enrollment Period (IEP) is a seven-month window that opens three months before the month of the 65th birthday, includes the birthday month, and closes three months after. Missing the IEP without qualifying for a Special Enrollment Period may result in permanent Part B premium penalties.
HSA contributions must stop upon Medicare enrollment. The IRS prohibits making HSA contributions once a person is enrolled in any part of Medicare, including Part A only. For many individuals, Part A enrollment is automatic at 65 if they are already receiving Social Security benefits. Those who defer both Medicare and Social Security past 65 may continue HSA contributions, but should verify their specific enrollment status before contributing.
HSA funds accumulated before Medicare enrollment may continue to be used tax-free for qualified medical expenses at any age, including Medicare premiums (with certain exceptions), out-of-pocket costs, and long-term care insurance premiums up to IRS-specified limits. After age 65, non-medical HSA withdrawals are taxed as ordinary income but are no longer subject to the 20% penalty.
California note: California does not conform to federal HSA rules. Contributions are not deductible on the California state return, and investment earnings within an HSA are generally subject to California income tax each year. Qualified medical distributions remain excluded from California income consistent with federal treatment. This significantly changes the cost-benefit analysis of the HSA as an investment vehicle for California residents.

Ages 66-67: Social Security Full Retirement Age
The Full Retirement Age (FRA) for Social Security is not a single age; it depends on birth year. Claiming at FRA produces the full, unreduced benefit. Claiming before FRA produces a permanently reduced benefit; claiming after FRA (up to age 70) increases the benefit through delayed retirement credits.
| Birth Year | Full Retirement Age |
|---|---|
| 1943-1954 | 66 |
| 1955 | 66 and 2 months |
| 1956 | 66 and 4 months |
| 1957 | 66 and 6 months |
| 1958 | 66 and 8 months |
| 1959 | 66 and 10 months |
| 1960 or later | 67 |
FRA is set by federal law under the Social Security Act as of the date this article was written. Verify the FRA applicable to a specific birth year with the SSA.
Source: SSA: Full Retirement Age
Age 70: Maximum Social Security Benefit
Social Security delayed retirement credits stop accruing at age 70. For each year benefits are deferred beyond FRA, the monthly benefit increases by approximately 8% per year (the exact rate is 2/3 of 1% per month). This credit accumulates from FRA through age 70; there is no additional benefit to claiming after 70.
For a beneficiary with a FRA of 67 who defers to 70, the age-70 benefit is approximately 24% higher than the FRA benefit. For a beneficiary with FRA of 66 who defers to 70, the increase is approximately 32%.
Whether deferring to 70 is the optimal strategy depends on health, longevity, other income sources, spousal benefit considerations, and other individual factors. There is no universal answer.
Social Security spousal benefits do not accrue delayed credits past FRA. A spousal benefit (based on the other spouse's record) reaches its maximum at the claiming spouse's FRA and does not increase by waiting past FRA. This distinction matters when coordinating claiming strategies between spouses.

Age 70½: Qualified Charitable Distributions from IRAs
A taxpayer who has reached age 70½ may make a Qualified Charitable Distribution (QCD) directly from a traditional IRA to an eligible charity. The QCD:
- Is excluded from federal taxable income (unlike a regular IRA distribution followed by a charitable deduction)
- Counts toward satisfying the annual RMD if the account is already subject to RMDs
- May benefit taxpayers who do not itemize deductions (since the exclusion applies regardless of whether the standard deduction is taken)
- May NOT be distributed to a donor-advised fund
- Must go directly from the IRA trustee to the qualifying organization; the account holder may NOT receive the funds first
The annual QCD limit is $111,000 per person for 2026, indexed for inflation. Married couples where both spouses have their own IRAs may each make a QCD up to the individual annual limit.
SECURE 2.0 added a one-time election to make a QCD to a Charitable Remainder Trust or Charitable Gift Annuity, subject to a separate inflation-adjusted limit ($55,000 for 2026). This option is available once per taxpayer and has specific structural requirements.
The 70½ threshold is precise: a person who turns 70 in January and reaches 70½ in July of the same year may begin making QCDs in that July. A person who turns 70 in August and reaches 70½ the following February must wait until that February.
California note: California conforms to the federal QCD exclusion for personal income tax purposes, meaning QCDs that are excluded from federal gross income are also excluded from California gross income.
Source: IRS Publication 590-B: Distributions from Individual Retirement Arrangements
QCD limits are indexed for inflation; verify the current limit with the IRS before making a distribution.
Required Minimum Distributions: Ages 72, 73, and 75
Required minimum distributions (RMDs) are the mandatory annual withdrawals from most tax-deferred retirement accounts. The age at which RMDs begin depends on when the account owner was born.
| Birth Year | RMD Starting Age | Law Governing |
|---|---|---|
| Born before July 1, 1949 | 70½ | Pre-SECURE Act law |
| Born July 1, 1949 through 1950 | 72 | SECURE Act 1.0 (2020) |
| Born 1951-1959 | 73 | SECURE Act 2.0 (2022) |
| Born 1960 or later | 75 | SECURE Act 2.0 (effective 2033) |
RMD ages reflect federal law as of the date this article was written and may be subject to further legislative change. The age 75 provision for those born in 1960 or later takes effect for distributions beginning in 2033.
What accounts are subject to RMDs
Accounts subject to RMDs during the original owner's lifetime include:
- Traditional IRAs
- SEP-IRAs
- SIMPLE IRAs (after the first two years of participation)
- 401(k), 403(b), and governmental 457(b) plans (unless still employed at the plan's sponsoring employer under certain plan designs)
Accounts not subject to lifetime RMDs:
- Roth IRAs (original owner)
- Roth 401(k)s (starting January 1, 2024, per SECURE 2.0)
The April 1 first-year extension
The first RMD may be delayed until April 1 of the year following the year the owner reaches the applicable starting age. This extension applies to the first RMD only; all subsequent RMDs are due by December 31 of the year in question. Taking advantage of the extension produces two taxable RMDs in the second year (the delayed first RMD and the regular second RMD), which may push income into higher brackets and affect IRMAA.
RMDs and inherited accounts
Inherited IRAs are subject to different RMD rules depending on the relationship of the beneficiary to the original owner, the date of death, and the beneficiary's status as an eligible designated beneficiary or a general beneficiary. For most non-spouse beneficiaries who inherit an IRA from someone who died after December 31, 2019, the 10-year rule applies: the entire inherited account must be distributed within 10 years of the date of death. Annual distributions within that 10-year period may be required in some cases depending on whether the original owner had already begun taking RMDs.
Source: IRS: Required Minimum Distributions
Age-Independent Milestones Worth Knowing
The following rules are not tied to a specific calendar age but often interact with age-based planning and are commonly overlooked.
SSDI and Medicare: 24-Month Window
A Social Security Disability Insurance (SSDI) recipient becomes eligible for Medicare after receiving SSDI benefits for 24 months, regardless of age. This is one of the few pathways to Medicare eligibility before age 65. For someone who begins receiving SSDI in their 40s or 50s, Medicare coverage may begin well before the standard age-65 enrollment window.

529-to-Roth IRA Rollovers: SECURE 2.0 (Effective 2024)
Beginning January 1, 2024, unused funds in a 529 college savings plan may be rolled over to a Roth IRA under the following conditions:
- The 529 account must have been open for at least 15 years
- The rollover is subject to the annual Roth IRA contribution limit ($7,500 for 2026)
- The lifetime cap for rollovers from any single 529 to the designated beneficiary's Roth IRA is $35,000
- The designated beneficiary of the 529 must own the receiving Roth IRA and must have earned income at least equal to the rollover amount in that year
- Contributions made to the 529 within the last five years (and earnings on those contributions) cannot be rolled over
- Income limits applicable to direct Roth IRA contributions do not apply to these rollovers
This provision allows families who over-funded 529 accounts for a child who received scholarships, chose a less expensive path, or did not attend college to redirect unused funds to retirement savings for the beneficiary without penalty or income tax.
These rules reflect SECURE 2.0 provisions as written; verify current IRS guidance before executing a rollover.
Roth IRA 5-Year Rule
In addition to reaching age 59½, tax-free distribution of earnings from a Roth IRA requires that the account has been open for at least five years, measured from January 1 of the year of the first Roth IRA contribution. A person who makes their first Roth IRA contribution in 2026 (regardless of the actual calendar date within 2026) satisfies the five-year rule starting January 1, 2031.
This rule is separate from the 59½ age requirement. Both must be met for earnings to be distributed entirely tax-free. Contributions to a Roth IRA (not earnings) may generally be withdrawn tax-free and penalty-free at any age.
For inherited Roth IRAs, the five-year clock of the original owner carries over to the beneficiary; a beneficiary who inherits a Roth IRA that has already satisfied the five-year rule may receive earnings tax-free.

How These Milestones Interact
No age-based rule exists in isolation. Several of the most consequential planning interactions involve multiple milestones working together.
The RMD and IRMAA interaction. Large traditional IRA or 401(k) balances create predictably large RMDs beginning at age 73 (or 75 for those born in 1960 or later). Those RMDs flow through to Modified Adjusted Gross Income, which determines IRMAA surcharges two years later under the lookback. A retiree who reaches 73 with a $3 million traditional IRA may face six-figure RMDs that push Medicare premiums into upper IRMAA tiers for the remainder of their retirement. Partial Roth conversions in the years between retirement and RMD age (often called the "conversion window") can reduce this future RMD burden, but each conversion year also adds to MAGI and triggers its own IRMAA consequence two years later.
The HSA stop and Medicare enrollment. For high earners still making HSA contributions in their early 60s, the timing of Medicare enrollment matters. A person who delays Medicare past 65 (because they are still working with employer coverage, for example) may continue HSA contributions. Enrollment in Part A alone (which can happen retroactively for up to six months when Medicare is applied for) can unexpectedly end HSA eligibility and may require retroactive correction of contributions already made.
Social Security and the survivor benefit window. A surviving spouse who takes survivor benefits at 60 may later switch to their own retirement benefit at 70 if their own delayed benefit would be larger. Conversely, a surviving spouse with a small own benefit might take their own retirement benefit at 62 and switch to survivor benefits at FRA. The optimal sequence depends on the amounts involved, and the decision made at age 60 has permanent consequences.
The super catch-up window. The SECURE 2.0 super catch-up bracket opens at age 60 and closes at 64. An investor who knows they will retire at 65 has a four-year window to make materially larger 401(k) contributions at the highest allowable catch-up rate before that window closes. For a high earner in their early 60s who has accumulated meaningful investable assets, the after-tax value of this additional deferral depends on marginal rates now versus expected rates in retirement.
These interactions are not unusual edge cases. For a near-retiree with a significant IRA balance, a working spouse, and a history of high income, several of these milestones are active simultaneously, and the timing of decisions about each one affects the outcome of the others.
