TSP Mistakes That Could Derail Your Retirement Goals—And How to Avoid Them

Key Takeaways:

  1. Small mistakes with your Thrift Savings Plan (TSP) can significantly impact your retirement. Knowing these pitfalls is the first step to staying on track.
  2. Proactive strategies can help you optimize your TSP and avoid common setbacks that derail your long-term financial goals.

Setting the Stage for a Secure Retirement

Your Thrift Savings Plan (TSP) is a cornerstone of your federal retirement benefits. It’s more than just a savings account; it’s a powerful tool to help you build a

secure financial future. But like any tool, improper use can lead to serious consequences. Retirement might feel far off—or just around the corner—but avoiding common TSP mistakes now can make a massive difference when the time comes to enjoy the fruits of your career.

Mistake 1: Not Maximizing Your Contributions

Are you contributing enough to your TSP? If not, you could be leaving free money on the table. Failing to contribute at least up to the matching threshold offered to federal employees is like turning down a pay raise.

Why It Hurts

When you don’t maximize your contributions, you’re missing out on compound growth, which can significantly boost your retirement savings over time. Even small shortfalls early in your career can result in tens—or even hundreds—of thousands of dollars less by retirement.

How to Avoid It

  • Make it a goal to contribute at least the maximum matchable percentage.
  • Consider increasing your contributions annually, especially if you receive a cost-of-living adjustment.
  • Utilize catch-up contributions if you’re over 50, allowing you to save even more each year.

Mistake 2: Ignoring the Importance of Diversification

Keeping all your eggs in one basket is rarely a good strategy, and your TSP investments are no exception. Over-reliance on one fund—or failing to adjust your allocation over time—can expose you to unnecessary risks.

Why It Hurts

Market volatility can wreak havoc on poorly diversified portfolios. If you’re heavily invested in stocks during a downturn or too conservative in your younger years, your portfolio could underperform when it matters most.

How to Avoid It

  • Review your TSP allocation at least annually to ensure it aligns with your risk tolerance and retirement timeline.
  • Use the TSP Lifecycle (L) Funds if you prefer a hands-off approach to diversification, as they adjust automatically as you near retirement.
  • Educate yourself on each TSP fund and its associated risks to make informed decisions.

Mistake 3: Withdrawing Funds Prematurely

Dipping into your retirement savings might be tempting during financial challenges, but early withdrawals can set you back significantly.

Why It Hurts

Not only will you pay penalties and taxes on early withdrawals, but you’ll also lose the potential growth that money could have generated over time. Every dollar you withdraw today could mean several dollars less in retirement.

How to Avoid It

  • Build an emergency fund outside your TSP to handle unexpected expenses without tapping into your retirement savings.
  • If you absolutely must withdraw, understand the long-term impact and explore options like a TSP loan instead of a withdrawal.

Mistake 4: Failing to Adjust for Inflation

Retirement is expensive, and inflation can erode your purchasing power over time. If you’re not factoring inflation into your retirement plan, you might find yourself falling short when you need it most.

Why It Hurts

Even modest inflation can significantly impact the value of your TSP savings over decades. Without adjustments, your retirement income might not stretch as far as you anticipate.

How to Avoid It

  • Include inflation assumptions in your retirement calculations. A typical estimate is 2-3% annually, but adjust this based on current economic trends.
  • Consider allocating part of your portfolio to funds that historically outpace inflation, such as stocks.

Mistake 5: Not Planning for Required Minimum Distributions (RMDs)

After age 73, the IRS requires you to start taking distributions from your TSP. Failing to do so comes with stiff penalties that can eat into your retirement savings.

Why It Hurts

Missing an RMD deadline results in a penalty equal to 25% of the required amount (reduced to 10% if corrected promptly). This unnecessary expense is entirely avoidable with proper planning.

How to Avoid It

  • Keep track of your RMD deadlines and amounts.
  • Work with a financial planner to integrate RMDs into your broader retirement income strategy.
  • Consider rolling over your TSP into an IRA, which might offer more flexibility with RMDs.

Mistake 6: Overlooking the Role of Fees

While the TSP is known for its low fees, even small costs can add up over time. If you’re not monitoring how fees impact your returns, you might be underestimating their effect on your savings.

Why It Hurts

Every dollar spent on fees is a dollar not working for you. Over decades, even small fees can cost you thousands of dollars in lost growth.

How to Avoid It

  • Regularly review your account statements to understand the fees you’re paying.
  • Compare the TSP’s fees to other investment options to ensure you’re getting the best deal.

Mistake 7: Not Coordinating TSP With Other Retirement Benefits

Your TSP isn’t your only retirement benefit as a federal employee. Social Security, pensions, and other savings accounts all play a role in your financial future. Failing to see the bigger picture can lead to poor planning.

Why It Hurts

Relying too heavily on one source of income—or neglecting to account for how your benefits work together—can create gaps in your retirement plan.

How to Avoid It

  • Develop a comprehensive retirement strategy that includes all your income sources.
  • Use online calculators or consult with a financial advisor to project how your TSP fits into your overall retirement picture.

Mistake 8: Underestimating Healthcare Costs

Healthcare is one of the most significant expenses retirees face. If you’re not preparing for these costs, you might struggle to cover them later.

Why It Hurts

Unexpected medical expenses can quickly drain your savings, leaving you financially vulnerable during retirement.

How to Avoid It

  • Consider supplementing your TSP with a Health Savings Account (HSA) if you’re eligible.
  • Factor healthcare costs, including Medicare premiums, into your retirement budget.

Mistake 9: Ignoring Beneficiary Designations

Who gets your TSP savings if something happens to you? If you haven’t updated your beneficiary designations, your money might not go where you intend.

Why It Hurts

Outdated or missing designations can lead to lengthy legal battles or your savings being distributed according to default rules rather than your wishes.

How to Avoid It

  • Review and update your beneficiary information regularly, especially after major life events like marriage, divorce, or the birth of a child.
  • Double-check that your TSP beneficiary forms align with your overall estate plan.

Mistake 10: Procrastinating Retirement Planning

Perhaps the biggest mistake is waiting too long to take retirement planning seriously. The earlier you start, the easier it is to build a solid financial foundation.

Why It Hurts

Procrastination limits your options and leaves you playing catch-up as retirement approaches. The power of compound interest works best when you give it time to grow.

How to Avoid It

  • Start planning for retirement as early as possible, even if it’s just small contributions to your TSP.
  • Set clear goals and create a roadmap to achieve them.
  • Reassess your plan regularly to ensure you’re on track.

Charting a Course Toward a Strong Retirement

Avoiding these common TSP mistakes isn’t about perfection—it’s about progress. By taking proactive steps to manage your TSP wisely, you can maximize its potential and secure the retirement you’ve worked so hard to achieve. Remember, small changes today can lead to significant improvements tomorrow.
