As a fee-only financial advisor in Santa Rosa, California, I work with individuals to navigate their retirement transition with personalized strategies. Whether you’re a few years away or already retired, knowing what not to do is just as important as knowing what to do.
In this post, we’ll cover some of the most common and costly mistakes retirees may make: many of which seem harmless in the early years, but may cause problems later. With professional guidance and careful planning, many of these issues can be addressed.
Let’s break them down, and more importantly, learn how to avoid them.
1. Retiring Without a Written Plan
Many people approach retirement with a general sense of readiness, but no clear, documented strategy. Without a plan for how you’ll draw income, manage taxes, and adjust for longevity, retirement may become a series of ad-hoc decisions.
This may lead to emotional spending or unnecessary frugality, missed tax-efficient opportunities, and gaps in healthcare or estate planning.
A thoughtful retirement plan doesn’t need to be hundreds of pages, but among many things, it should coordinate income sources, withdrawal order, investment risk, tax strategy, and legacy goals.
Tip: Start with a written retirement income/withdrawal plan that maps out the stages of retirement: early "go-go" years, mid-retirement stability, and later healthcare-focused years. Revisit it annually.

2. Claiming Social Security Too Early
Many retirees take Social Security at 62 simply because they can. But claiming early comes with a permanent reduction in benefits; about 30% lower than if you waited until your Full Retirement Age (FRA) of 67 (if you turn 62 in 2025). While early claiming may be the right choice in some cases, it often locks in reduced lifetime income and limits future flexibility.
Also, your benefit will increase if you delay claiming past your full retirement age; by about 8% for each full year, up to age 70. These are called delayed retirement credits and may substantially increase your benefit over time.

Tip: If you have good health and savings, delaying Social Security may increase lifetime benefits, but it's important to evaluate this within your full financial plan

3. Not Having a Withdrawal Strategy
Without a coordinated plan for which accounts to draw from, and when, you may not optimize tax-efficiency, trigger Medicare IRMAA surcharges, or run out of money sooner than expected.
Many retirees may overlook the benefits of proactive planning around Required Minimum Distributions (RMDs). While RMDs are mandatory starting at age 73, it may be wise to withdraw more earlier, especially in low or no-tax years, such as the early retirement window before Social Security or pension income begins. This may reduce future RMDs and potentially keep you in a lower tax bracket longer.
You might also consider Roth conversions during these low-income years to build future tax-free income.
Another common oversight: donating to charity from a taxable account when you’re eligible for a Qualified Charitable Distribution (QCD) from an IRA. QCDs may satisfy your RMD and may reduce taxable income while maximizing charitable impact.
Tip: Design a flexible, tax-efficient withdrawal plan early, and revisit it regularly. Consider Roth conversions and QCDs to optimize both taxes and charitable giving.

4. Ignoring Inflation and Rising Costs
Inflation quietly erodes purchasing power. Over a 25–30 year retirement, a fixed income may not keep up, especially with rising healthcare, housing, and everyday expenses.
You may have heard a lot about investing in retirement to generate income, but chasing returns can lead to taking on unnecessary risk. Instead of focusing solely on income or growth, consider your cash flow needs. There are two ways to generate gains: price appreciation and interest/dividends. A sustainable retirement strategy often blends both, but should always be rooted in your personal goals, risk tolerance, and timeline.
Don’t underestimate TIPS (Treasury Inflation-Protected Securities). Though not as popular as other investments, TIPS are specifically designed to protect your investment from inflation, making them a vital tool in combating rising costs over time.
Equity may also be helpful in combating inflation over the long run, as businesses often pass increased costs onto consumers, which may be reflected in price appreciation.
Tip: Build in flexibility and inflation protection, but don’t take on risk you don’t need. Focus on your total income picture, not just one source of return.
5. Holding Too Much in Cash (or Too Much in Stocks)
After decades of saving, some retirees become overly cautious, keeping too much in cash or low-yield accounts. The problem? Cash loses value over time due to inflation, and may not generate enough income to support a 20–30 year retirement.
On the flip side, some retirees stay overly aggressive, leaving too much exposed to market volatility. A sharp downturn early in retirement, known as sequence of returns risk can potentially undermine your long-term strategy if you're drawing from investments during a market dip.
The key is finding the right balance. Your retirement portfolio should be designed to generate stable income, preserve capital, and grow moderately to keep pace with inflation.
Tip: Align your portfolio with your time horizon, income needs, and risk tolerance. A mix of cash, bonds, and equities; thoughtfully allocated can help support a more stable retirement.

6. Overlooking Tax Planning Opportunities
Taxes don’t stop in retirement and without careful planning, they can take a bigger bite out of your income than expected. Withdrawals from traditional IRAs and 401(k)s are taxed as ordinary income, and large distributions can push you into higher tax brackets or trigger Medicare premium surcharges (IRMAA). Many retirees also may miss opportunities in low-income years, like the early years of retirement before RMDs begin.
Strategic tax planning in retirement may add efficiency in your lifetime tax bill and help preserve more of your wealth. This includes not just having tax efficiency in income taxes, but also managing capital gains, optimizing account withdrawals, and taking advantage of tax-smart giving.
Tip: Depending on your tax situation, strategies like Roth conversions, tax-loss harvesting, or QCDs may offer advantages. Consult a tax advisor or financial planner to assess suitability.

7. Underestimating Longevity
Many retirees plan based on average life expectancy, but about half of people might live longer than average. With improved healthcare and lifestyle habits, it’s not uncommon to live well into your 90s. Planning for only 20 years of retirement income may leave you short if your retirement lasts 30 years or more.
Longevity risk, the chance of outliving your money, is one of the most significant yet overlooked threats to retirement security. It’s especially problematic if spending is too high early on, investment returns are lower than expected, or healthcare costs rise significantly later in life.
Tip: It may be prudent to account for the possibility of living into your 90s or beyond. Your retirement strategy should support 30+ years of income, account for inflation and healthcare costs, and adapt as your needs evolve.
8. Not Working With a Fiduciary Advisor
Retirement decisions are complex, and working with an professional may provide perspective and support. Fiduciary advisors are legally obligated to act in a client’s best interest under the Investment Advisers Act of 1940.
Rather than focusing on products or transactions, a fiduciary takes a holistic view of your financial life; covering retirement income, tax strategy, healthcare planning, and estate considerations.
Tip: Look for an fiduciary, fee-only advisor who can serve as a long-term planning partner and may provide structured guidance and help you make informed decisions.
