For generations, the Thrift Savings Plan (TSP) has anchored the retirement security of millions of federal employees and service members. As one of the largest retirement programs in the world, it empowers public servants to grow their savings, manage taxes wisely and move toward a confident, independent retirement. But with new TSP rules, rising contribution limits and the scheduled expiration of key tax provisions in 2026, federal employees face an important turning point. Understanding these updates and acting strategically before they take effect could significantly improve your long-term financial outlook.

This 2026 TSP strategy guide breaks down the most important rule changes, tax implications and action steps federal workers should consider to keep their retirement plan strong.

1. Rising TSP Contribution Limits

Each year, the IRS adjusts contribution limits to keep pace with inflation. For 2025, employees can contribute up to $23,000, plus an additional $7,500 catch-up contribution if age 50 or older.

By 2026, these limits are expected to rise again, creating an opportunity to save even more before tax brackets potentially increase.

Strategy Tip:

Maximize contributions now while tax rates remain historically low. Every extra dollar saved and invested before 2026 compounds for decades and could shield more income from future taxes.

2. Automatic Catch-Up Contributions for Employees 50+

Previously, older federal employees had to manually activate their catch-up contributions. Now, once you reach your annual contribution limit, any additional contributions automatically count toward your catch-up amount.

This update makes saving for retirement simpler and ensures that no eligible employee misses out.

Strategy Tip:

If you’re 50 or older, confirm that your payroll deductions are set up to capture these automatic catch-up contributions. It’s one of the easiest ways to accelerate your TSP growth.

3. The Growing Importance of the Roth TSP

With potential tax increases ahead, the Roth TSP’s appeal continues to rise. Paying taxes now, at today’s lower rates, and withdrawing tax-free later can provide major advantages in retirement.

Under the SECURE Act 2.0, Roth TSP participants now enjoy expanded flexibility:

• Employer contributions can be directed to Roth accounts (taxable in the year received).
• Roth TSP balances can be rolled directly into Roth IRAs.
  

Strategy Tip:

If you expect to be in a higher tax bracket in retirement, gradually shift more of your contributions to the Roth TSP over the next year. It’s a tax-smart move that builds long-term stability.

4. RMD (Required Minimum Distribution) Age Increases

The SECURE Act 2.0 also raised the age when retirees must begin taking withdrawals from tax-deferred accounts:

• 73 in 2025
• 75 by 2033
  

This gives retirees additional years to grow their savings and plan distributions more strategically.

Strategy Tip:

Use this window to perform partial Roth conversions between retirement and your RMD age. Converting smaller amounts over several years can help manage taxes efficiently and reduce future taxable income.

5. Simplified Access to TSP Loans and Withdrawals

The TSP’s enhanced online platform now makes it easier to request loans or withdrawals, separating Roth and Traditional balances and allowing digital signatures for faster processing.

While these upgrades increase convenience, it’s essential to understand the long-term tradeoffs. Withdrawals or loans reduce your compounding growth potential and could delay your retirement goals.

Strategy Tip:

Treat TSP loans as a last resort. Every dollar you borrow today could cost you several dollars in lost growth later.

6. Potential Adjustments to Matching Contributions

There’s growing discussion about possible adjustments to agency matching formulas to better account for inflation and years of service. While no official changes are confirmed, future enhancements could provide greater rewards for long-term employees.

Strategy Tip:

Stay informed through the Federal Retirement Thrift Investment Board (FRTIB). If matching rules change, adjust your contributions immediately, don’t leave free money unclaimed.

7. Lifecycle (L) Fund Adjustments and Investment Flexibility

The TSP’s Lifecycle Funds (L Funds) automatically rebalance your investments as you approach retirement. As market conditions and inflation trends evolve, these funds may adjust their stock-to-bond ratios to help protect participants from volatility.

Strategy Tip:

Revisit your TSP allocation annually. Choose an L Fund that reflects your target retirement date and comfort with risk, or build a custom mix if you prefer more control.

With potential tax bracket increases around the corner, now is the time to get proactive about tax diversification.

Here’s what you can do:

• Balance your accounts: Split contributions between Traditional (pre-tax) and Roth (after-tax) to hedge against future rate changes.
• Coordinate with your other benefits: Plan your TSP withdrawals alongside your federal pension and Social Security income.
• Plan ahead for RMDs: Early withdrawals or conversions can help minimize tax burdens later.
• Stay adaptable: Review your plan annually to ensure it still aligns with your income and retirement goals.

The next two years represent a rare opportunity to strengthen your position before tax laws change.

Consider:

• Maximizing contributions while current tax rates remain low.
• Exploring Roth conversions to balance pre-tax and post-tax income.
• Reviewing withdrawal strategies before higher rates take effect.
• Monitoring updates from the IRS and FRTIB to stay ahead of rule changes.
