What Is the Biggest Mistake Most People Make Regarding Retirement?
The single biggest retirement mistake is failing to build a written income distribution plan before leaving the workforce. Without one, even substantial savings can create anxiety, tax exposure, and the risk of outliving your money.
KEY TAKEAWAYS
- ✓ The most common and costly retirement mistake is entering retirement without a written income distribution plan that coordinates all income sources.
- ✓ Tax planning in retirement is often overlooked — Connecticut taxes retirement income for higher earners, making tax-sensitive withdrawal strategies especially important for CT residents.
- ✓ Underestimating longevity and healthcare costs ranks among retirees' most common regrets.
- ✓ A comprehensive plan integrates investments, tax strategy, Social Security timing, and estate considerations into a single coordinated approach.
- ✓ The earlier you address these gaps — ideally three to five years before retirement — the more options you have to correct course.
No Written Income Plan: The Mistake That Costs Retirees the Most
Most people spend decades focused on accumulation — saving, investing, and building a balance. Yet the transition from saving to spending requires an entirely different strategy. According to research by the Employee Benefit Research Institute, more than half of American workers have never calculated how much income they will need in retirement.
A written income distribution plan coordinates your Social Security timing, required minimum distributions (RMDs), withdrawal sequencing across taxable and tax-deferred accounts, and projected expenses. Without that coordination, you may pay significantly more in taxes than necessary, draw down accounts in the wrong order, or face a retirement income shortfall even with a seven-figure portfolio.
This is the planning gap that a CFP professional — particularly one with a CRPC designation specializing in retirement transitions — is specifically trained to close. The good news: it is entirely avoidable with the right guidance, ideally starting three to five years before your target retirement date.

The Top Retirement Mistakes — and How to Avoid Them
1. No Coordinated Income Plan
Treating Social Security, RMDs, pension income, and investment withdrawals as separate decisions rather than a coordinated system is the defining mistake. The order in which you draw from accounts has significant tax and longevity implications.
2. Ignoring the Tax Picture in Retirement
Many pre-retirees assume taxes drop sharply once they stop working. For those with significant pre-tax savings, RMDs can push taxable income higher than expected. While Connecticut's 2026 IRA exemption reduces the state tax burden for eligible taxpayers, federal taxes and potential loss of the CT exemption at higher income levels still require specific planning.
3. Claiming Social Security Too Early
Claiming Social Security before full retirement age locks in a permanently reduced benefit. For someone retiring at 62 rather than 70, the difference in lifetime benefit can be substantial. Social Security timing should be modeled as part of a broader income plan, not decided in isolation.
4. Underestimating Longevity and Healthcare
A 65-year-old couple today has a meaningful probability that at least one spouse lives into their 90s. Healthcare costs tend to increase with age. According to Fidelity's 2025 estimate, an average couple may need approximately $345,000 to cover healthcare expenses in retirement, excluding long-term care. Portfolios designed for a 20-year retirement may fall short in a 30-year one.
5. A Portfolio Not Aligned with Income Needs
Accumulation and distribution require different portfolio structures. A portfolio optimized for long-term growth may expose a retiree to sequence-of-returns risk — meaning early market downturns can disproportionately harm portfolio longevity when withdrawals are ongoing.
6. Waiting Too Long to Plan
The years between ages 55 and 65 are often the highest-leverage planning window. Roth conversion opportunities, pre-retirement tax positioning, and Social Security analysis all benefit from a multi-year runway.
Why Retirement Planning in Connecticut Requires Extra Attention
Connecticut has a specific retirement income tax structure that requires careful attention, even with the expanded exemptions now in effect as of 2026. While eligible taxpayers below the AGI thresholds can now fully exempt IRA distributions, pension income, and Social Security from state tax, higher-income retirees may still face a meaningful CT tax burden. For individuals and households with $1 million or more in retirement savings, a properly coordinated withdrawal strategy may help manage income to stay within or near the exemption thresholds.

Frequently Asked Questions
What are the top 5 retirement mistakes?
The five most common retirement mistakes are: (1) entering retirement without a written income plan; (2) claiming Social Security too early without modeling the long-term impact; (3) underestimating taxes on retirement income, including RMDs; (4) underestimating healthcare and longevity costs; and (5) keeping a portfolio structured for accumulation rather than income distribution.
What is the number one reported regret of retirees?
Survey data consistently show that Social Security timing ranks among the top regrets of retirees — specifically, claiming benefits too early. Many retirees also report wishing they had planned more carefully for healthcare expenses and started the planning conversation with a professional advisor earlier.
What is the $1,000 a month rule for retirees?
The $1,000 per month rule is a rough planning shorthand suggesting that for every $1,000 of monthly retirement income you want, you may need approximately $240,000 in savings, based on a 5% annual withdrawal rate. This rule is a starting point for conversation, not a plan.
How much money do you need to retire in Connecticut?
Connecticut's cost of living, tax structure, and healthcare costs all factor into retirement income needs. Many financial planning frameworks suggest targeting 70 to 90 percent of pre-retirement income annually. Connecticut residents should also account for the state's tax treatment of retirement income — including the 2026 IRA exemption and its income eligibility thresholds — when modeling their income needs. A personalized income analysis provides a far more reliable figure than any general estimate.
