You’ve worked hard to earn your benefits—now it’s time to make sure you keep more of them. After working with thousands of federal employees over the years, one of the biggest regrets we hear is, “I wish I had started these tax-saving strategies earlier.” The good news? Whether you’re still working or already retired, it’s not too late.
This article outlines some of the best hidden tax-saving opportunities available to federal employees. While not every strategy will apply to every person, the right mix can make a dramatic difference to your bottom line.
1. The Roth TSP (and Roth Conversions) – Your Secret Weapon
Let’s start with what’s arguably the most powerful opportunity federal employees overlook: the Roth TSP.
When you contribute to the Roth TSP, your contributions are made after-tax, meaning you don’t get a deduction now, but your earnings grow tax-free and your withdrawals in retirement are also tax-free. Compare that to the traditional TSP, where all your withdrawals—including earnings—are taxed as ordinary income.
If you’re still working, it’s worth evaluating whether contributing more to the Roth side makes sense now, particularly if you’re in a lower tax bracket or expect higher income in retirement due to pensions, Social Security, or required minimum distributions (RMDs).
But what if you’re already retired? That’s where Roth conversions come in.
A Roth conversion allows you to transfer money from your Traditional TSP or IRA into a Roth IRA. Yes, you’ll pay taxes on the conversion amount in the year of the transfer—but all future growth will be tax-free, and Roth accounts are not subject to RMDs.
The RMD age is now 73 for those born between 1951–1959 and will increase to 75 for those born in 1960 or later.
Why this matters: Once RMDs kick in, they can push you into a higher tax bracket, affect your Medicare premiums, and reduce your financial flexibility. Strategic Roth conversions in the early years of retirement—before RMDs begin—can smooth out your taxable income and lower your lifetime tax burden significantly.
2. Leverage “Asset Location” – Not Just Allocation
You’ve probably heard of asset allocation (stocks vs bonds), but very few feds know about asset location—where you place those investments.
The concept:
- Growth investments (e.g., C Fund, S Fund, I Fund) should go in Roth accounts, where earnings grow tax-free.
- Conservative investments (e.g., G Fund, F Fund) should go in Traditional accounts, since the limited growth will eventually be taxed anyway.
Don’t misunderstand this strategy—it doesn’t mean you should put all your traditional money into conservative investments and all your Roth money into aggressive ones. Instead, it means that if you’re going to have aggressive investments in your portfolio, they should be prioritized in your Roth account first. That’s where growth has the most long-term tax advantage.
The problem? The TSP doesn’t allow you to split your investment mix between Traditional and Roth separately—they’re treated as one portfolio. To work around this, many federal employees roll their TSP funds into Traditional and Roth IRAs during retirement, giving them complete control.
Why it works: Proper asset location can result in hundreds of thousands of dollars in additional after-tax wealth over time.
3. Tax-Deductible FEHB Premiums – A Limited-Time Opportunity
Another overlooked tax benefit applies to your Federal Employees Health Benefits (FEHB) premiums.
While you’re working, your FEHB premiums are pre-tax, reducing your taxable income. However, once you retire, this tax benefit goes away.
But here’s the trick:
If you and your spouse are both federal employees, the spouse who continues working should carry the health insurance for both of you. That way, you can continue getting the pre-tax benefit for the entire family—even if one spouse is retired.
Pro tip: This can save thousands in taxes over a 3–5 year period if one spouse continues working while the other retires early.
4. Charitable Giving – Doing Good While Saving Big
If you’re charitably inclined, the tax code offers you a few big opportunities—especially in retirement.
a. Qualified Charitable Distributions (QCDs)
Once you reach age 70½, you can donate directly from your IRA to a qualified charity—up to $108,000 in 2025. This doesn’t count as taxable income, but it still satisfies your RMD.
QCDs reduce your adjusted gross income, which in turn helps lower taxes and avoid IRMAA surcharges on Medicare.
b. “Bunching” Charitable Contributions
The standard deduction in 2025 is $30,000 for married couples. That means many people who donate $10,000–$15,000 a year don’t see any extra tax benefit unless they itemize.
The fix? Bunch your charitable giving—donate 2–3 years’ worth in a single year, then skip donations the next year. You’ll exceed the standard deduction and get a bigger tax break.
Example: Donating $15,000 per year? Instead, donate $45,000 in one year and deduct the full amount.
You can also use a Donor-Advised Fund (DAF) to bunch the donation for tax purposes, but spread out the actual donations to charities over time.
5. Avoiding Medicare Premium Surprises (IRMAA)
Most federal employees underestimate how TSP withdrawals can push them into higher Medicare brackets.
For 2025, Medicare Part B premiums increase if your Modified Adjusted Gross Income (MAGI) exceeds:
- $106,000 (single)
- $212,000 (married)
Strategic planning—such as Roth conversions in low-income years, or timing large TSP withdrawals carefully—can help you stay below these thresholds and avoid costly IRMAA surcharges.
6. Relocating to a Tax-Friendly State
While not a fit for everyone, moving in retirement can significantly reduce your tax bill. States like Florida, Texas, Nevada, South Dakota, and Wyoming have no state income tax.
This means your pension, Social Security, and TSP withdrawals are not taxed at the state level—a major win for retirees with large federal pensions and TSP balances.
Federal taxes still apply, but a zero state income tax could save you thousands annually.
Final Thoughts: Take Action Now
Tax planning isn’t just for April—it’s a year-round opportunity, especially for federal employees with multiple income streams in retirement. Small changes today can lead to massive savings tomorrow.
We’ve helped countless federal employees implement these strategies, and the difference is life-changing—more money for travel, legacy planning, and peace of mind.
If you’re serious about minimizing taxes and making the most of your retirement, now is the time to act.
