Navigating Social Security and Medicare in a changing world

Retirement planning involves more than saving — Social Security and Medicare decisions matter too. Explore key filing considerations, potential pitfalls, and how thoughtful planning with your advisor can help you navigate these programs with clarity and confidence.

If you’re planning for retirement, you’re likely wondering how Social Security will fit into your long-term financial picture.

Concerns about the program’s future have grown in recent years as costs have outpaced trust fund income. Since 2021, Social Security’s expenses have exceeded the revenue flowing into the Old-Age and Survivors Insurance (OASI) trust fund. That gap is expected to continue under current assumptions, prompting many people to question what their benefits might look like in the years ahead.

If you’re contributing to Social Security through FICA taxes but not yet claiming benefits, this outlook matters. According to the 2026 Trustees Report, the system is projected to pay full benefits through 2032. After that, ongoing payroll tax revenue is projected to cover approximately 78% of scheduled benefits. Without legislative changes, this may result in reduced benefits if Congress doesn’t act.

The reality is complex, but not as dire as some headlines suggest. Social Security is projected to continue paying benefits, though adjustments may be needed. That’s why developing a thoughtful, personalized claiming strategy is more important than ever.

Because Social Security and Medicare decisions aren’t one-size-fits-all, the right approach depends on your income needs, your health coverage timeline, and how your earnings may affect your premiums. The three questions below can help you evaluate these factors and build a filing strategy that fits your situation.

What does the “breakeven” filing age represent, and if I don’t need Social Security to live off of, would I be better off filing at age 62 and investing the proceeds?

The concept of a Social Security breakeven age can be a helpful starting point when evaluating when to claim benefits. At its core, breakeven represents the age at which the cumulative value of delaying benefits overtakes the total you’d receive by claiming early. In other words, it’s the trade-off between taking a reduced benefit for a longer period versus waiting to receive a higher monthly amount. While the math is straightforward, the decision itself is more nuanced, particularly since claiming at 62 can reduce benefits by roughly 30%, delaying past full retirement age increases benefits by about 8% per year up to age 70.

For some individuals, an alternative approach is to claim benefits early and invest the proceeds. This strategy can provide added liquidity and flexibility, especially if you have other income sources or a shorter anticipated time horizon. However, it’s important to weigh this against the trade-offs. Early claiming permanently reduces your benefit base, which not only lowers lifetime income potential but also results in smaller cost-of-living adjustments and survivor benefits over time. And while investing those early payments may offer growth potential, it introduces market risk, whereas the increase from delaying Social Security represents a guaranteed adjustment under current rules.

As with most planning decisions, the best approach depends on your personal circumstances and should be evaluated within the context of a comprehensive financial plan.

When should I file for Medicare?

The most common time to enroll in Medicare is during your Initial Enrollment Period (IEP), which is a seven-month window that begins three months before you turn 65, includes your birth month, and extends three months after. For most individuals who are retiring or don’t have qualifying employer coverage, enrolling during this window helps avoid late enrollment penalties and ensures timely coverage. Signing up during the two to three months leading up to your 65th birthday generally ensures coverage beginning on the first day of the month when you turn 65.

If you (or your spouse) are still working and covered under an employer-sponsored health plan, you may qualify for a Special Enrollment Period (SEP). This allows you to delay Medicare Part B (and sometimes Part D) without penalty and enroll within eight months of losing the qualifying coverage. This is especially relevant if you’re covered by a large employer plan (generally 20 or more employees), where Medicare is secondary while still employed.

If you miss both your IEP and SEP, you may need to enroll during the General Enrollment Period (GEP), which runs annually from January 1 through March 31. Coverage typically begins July 1 for those who enroll during this window.

What is IRMAA, and how does it impact my premiums?

Income-Related Monthly Adjustment Amount (IRMAA) is a surcharge added to Medicare Part B and Part D premiums for higher-income beneficiaries as defined by Medicare. While most individuals pay a standard Part B premium, those with income above certain thresholds pay progressively higher premiums based on their income level. IRMAA is determined by using your modified adjusted gross income (MAGI) from your federal tax return two years prior.

MAGI for IRMAA purposes is your adjusted gross income (AGI) plus tax-exempt interest income, which can catch some retirees off guard, especially those holding municipal bonds or realizing significant capital gains. One-time events, such as the sale of a business, large Roth conversions, or significant portfolio rebalancing, can push you into higher IRMAA brackets and increase Medicare costs for at least one year.

Common pitfalls

Enrollment timing, income decisions, and coordination with a spouse can all influence your Social Security and Medicare benefits. The pitfalls below highlight the areas where people most often run into issues, and where a bit of planning can make a meaningful difference.

Missing the Initial Enrollment Period and Special Enrollment Period

Missing both your IEP and any SEP can lead to lifelong premium penalties, coverage gaps, delayed enrollment, and reduced plan options, including potential underwriting or denial for Medigap coverage.

Health savings account contribution timing

Once you’re enrolled in any part of Medicare, including Part A, you’re no longer eligible to make health savings account (HSA) contributions, and contributions made after that point can trigger tax penalties. As a result, individuals who want to maximize HSA contributions should generally stop contributing at least six months before enrolling in Medicare to avoid excess contributions and potential IRS penalties.

Not coordinating spousal and survivor benefits

Failing to coordinate Social Security claiming decisions as a household can cause couples to miss opportunities to strengthen spousal and survivor benefits, particularly when delaying the higher earner’s benefit may increase long-term survivor income. Working with an advisor to evaluate each spouse’s own benefit, spousal benefit, and survivor benefit options can help preserve lifetime income and reduce the risk of leaving benefits on the table.

Overlooking earnings limits and taxation

Claiming Social Security before full retirement age while you’re still working can temporarily reduce cash flow, as benefits may be withheld if your earnings exceed annual limits. However, withheld benefits are generally credited back through a benefit recalculation once you reach full retirement age.

In addition, because up to 85% of Social Security benefits may be taxable depending on your combined income, many individuals underestimate the combined impact of earnings limits and taxation on their net retirement income.

Planning for what comes next

Social Security and Medicare have changed over time and will likely continue to evolve. The good news is that thoughtful planning goes a long way. By understanding the key Social Security and Medicare decision points, avoiding common pitfalls, and planning ahead, you can create a filing approach that fits your needs. When you coordinate with your financial advisor and review how filing age, income, and coverage choices fit into your broader retirement plan, you’re better positioned to make informed decisions that support your long-term goals.

Key takeaways

Social Security and Medicare decisions can have a lasting impact on retirement income, and evaluating them within the context of a comprehensive financial plan can be helpful.
