Gen X Is Next. Here Are the Social Security Mistakes to Avoid.

For years, America's retirement conversation focused on Baby Boomers. As this large generation reached their early sixties, Social Security became the first major source of income for millions of households. The financial planning industry literally built entire practices around this moment.

Now, however, the conversation is shifting. Gen X is next up in line, bringing new challenges and considerations to the forefront.

And Gen X arrives with a different set of pressures than the generation before them. Fewer people in this cohort have pensions. Retirement saving has been sort of a do-it-yourself project: 401(k)s, IRAs, whatever they could piece together between the mortgage, the kids, the career changes, and the occasional layoff. Many got a later start than they planned. Running underneath all of it is a quiet, persistent worry that a lot of Gen Xers won't say aloud but feel the weight of constantly: what if the money runs out?

The uncomfortable truth is that many Gen X households haven't yet done serious retirement planning. Only a minority of them work with a financial advisor. That gap really does matter a whole lot more than it might seem, because Social Security is no longer a small detail. For many households, it's the foundation on which everything else is built. It can cover a meaningful portion of the income gap between what someone has saved and what they need to live off of. That is, only if the decisions get made correctly. The mistakes in this area are common, costly, and—on the bright side—avoidable.

Treating Social Security as Automatic

The most widespread mistake is also the most basic: assuming that Social Security just happens when you retire. You file, you get a check, done. Unfortunately, it’s not as simple as that. Social Security involves strategic decisions, and those decisions affect not just your monthly income but your spouse's benefit, what a surviving spouse will receive after you're gone, how much of your benefit gets taxed, and even what you pay for Medicare. 

A lot of people leave pretty significant amounts of money on the table, without ever realizing it, because they treat it as an automatic process instead of a planning decision.

Not Understanding How Your Earnings Shape Your Benefit

Your Social Security retirement benefit is calculated based on your highest 35 years of earnings, adjusted for inflation. That may sound straightforward, but two things trip people up on a regular basis.

Low-earning years don’t disappear; they’re averaged in, pulling down your benefit if you had gaps, part-time work, or low-income years. But continuing to work and earning more can replace weaker years on your record, raising your benefit.

This matters especially for Gen X, because careers in this generation have often been messy in ways earlier generations didn't experience as widely. Layoffs during the dot-com bust or the financial crisis. Pivots into self-employment. Time out of the workforce for caregiving. Years of part-time work while raising kids. All that shows up in the earnings record, and it's worth knowing what it looks like before assuming your benefit is set in stone.

There's also a trap that self-employed Gen Xers fall into with some frequency. The logic goes: pay yourself less, reduce your self-employment tax burden, and keep more money in the business. In the short term, it can feel like smart financial management. The problem is self-employment income is what Social Security uses, and your earnings record determines your benefit. Systematically underreporting income to avoid payroll taxes today can quietly reduce guaranteed, inflation-adjusted retirement income for the rest of your life. That's a tradeoff worth running the numbers on, not just assuming it's a win because the tax bill is lower this year.

Claiming Too Early Without a Real Reason

Claiming at 62 is very common. Sometimes it's the right health issues, financial necessity, or a situation where the math genuinely supports it. But oftentimes, it's purely emotional. Which isn’t necessarily a bad thing in and of itself: Some people claim early because they feel burned out from years of work, fear Social Security will run out, or worry they may not live long enough to benefit. Others want to recoup what they've paid in, seeking validation or relief. 

The tough reality is that often these emotional decisions are made without fully considering the long-term impact, driven by these underlying anxieties or a desire for immediate reassurance.

The danger is in focusing on the first few years rather than the last twenty. A benefit that's 25 to 30 percent smaller might feel fine at 63, but at 83, when portfolio returns are uncertain, and healthcare costs are climbing, that gap compounds in ways that are hard to reverse. A larger monthly benefit later in life reduces pressure on the portfolio, lowers the odds of running out of money, and provides more security for a surviving spouse. That's why Social Security is best understood not as a return on investment to be maximized in the near term, but as a longevity insurance, a guaranteed income floor that gets more valuable the longer you live.

Missing Spousal Benefit Opportunities

Spousal benefits are among the most misunderstood parts of the Social Security puzzle, and couples routinely make decisions that cost them money they didn't fully know was available.

A few things worth understanding clearly: the spousal benefit is calculated based on the worker's primary insurance, the benefit they'd receive at their full retirement age, not the actual amount they chose to claim. The worker typically needs to have filed before a spouse can collect a spousal benefit. And the age at which the spouse claims matters; claiming early reduces the spousal benefit, just as it reduces a worker's own retirement benefit.

Couples often make Social Security decisions without working together on it, missing opportunities to coordinate timing and optimize both benefit amounts. Without guidance, these uncoordinated choices are common and can reduce long-term income.

Widows and Widowers Missing the Switching Strategy

Survivor benefits are another big consideration of Social Security and among the most consistently overlooked.

A surviving spouse often has options that most people don't know exist. In many situations, you can start with one benefit, often the survivor benefit, and then switch to your own retirement benefit at a later age or do it in reverse. The optimal sequence depends on the specific dollar amounts, the ages involved, and the projected timeline. Done well, this strategy can meaningfully increase the surviving spouse's lifetime income. Done without guidance, people often lock in the wrong benefit permanently at one of the most difficult moments of their lives.

This is exactly where good advice counts, not because the rules are impossibly complicated, but because the stakes are high, the decision is irreversible, and it tends to happen when someone is grieving and least equipped to think through the long-term implications.

Ignoring Taxes Until It's Too Late

The tax piece of Social Security catches people by surprise more often than anything else in retirement planning.

Because the income thresholds that trigger Social Security taxation were set in the 1980s and never meaningfully adjusted for inflation, a large share of retirees end up paying federal income tax on up to 85 percent of their benefits, often without expecting it. The first year of Social Security can bring unexpected withholding problems, a surprise April tax bill, and, in some cases, higher Medicare premium brackets triggered by income that just pushes over a threshold.

For Gen X, the years between retirement and when Social Security begins are often the best window you'll ever have for tax planning. Income tends to be lower in those years, creating space for Roth conversions, strategic IRA withdrawals, and thoughtful income source sequencing. Building a tax map before benefits start, understanding how your Social Security income interacts with IRA distributions, any pensions, and eventually required minimum distributions, can reduce your lifetime tax burden. But it requires doing the work before the switch gets flipped, not after.

A Quick Check Before the Window Closes

If you're Gen X, five questions are worth sitting with honestly. Do you know your estimated benefit at 62, at full retirement age, and at 70? Have you reviewed your earnings record for errors? Mistakes are more common than people realize, but the good news is  they can be corrected if they’re caught early. If you're married, have you coordinated the plan as a couple rather than making two separate decisions that don't account for each other? Do you know what the income picture looks like when one spouse dies? And do you have a sense of what the tax impact could be once benefits begin?

If the answer to any of those is "not really," you're in the majority. But you're also closer to the decision window than you might feel. Social Security planning doesn't require turning your entire financial life over to someone on the first meeting. A good first conversation can start with just a few pieces of information, birthdates, benefit estimates, a rough sense of health and longevity, and a basic picture of other income sources. From there, the Social Security plan connects naturally to everything else: taxes, withdrawals, investment strategy, and long-term security.

If you're within ten years of retirement, doing this work now, while you still have meaningful choices, is worth far more than waiting until the decision is already in front of you.
