The 'TurboTax Military Discount' & Better Alternatives

Service members get a “discount” on TurboTax. Often the turbotax military discount means free filing for E-1 to E-9 enlisted ranks. That’s a nice perk. But free filing is not the same as correct filing.

Military tax law is complex:

• State of Legal Residence: You might be stationed in California (high tax) but are a resident of Florida (no tax).
• Combat Zone Exclusion: Income earned in designated zones is tax-free.
• Thrift Savings Plan (TSP): Similar to a 401(k) but with specific rules.

Key Takeaways

• TurboTax handles the basics but can struggle with multi-state military spousal income (MSRRA).
• MilTax (provided by DoD) includes free tax prep and consultation with experts who know military law.
• The 'State of Legal Residence' error is the most common and costly mistake for service members.
• Don't overlook the 'Combat Zone' exclusion rollover opportunities for Roth IRAs.

MilTax vs. TurboTax

MilTax:

• Cost: Free (funded by the DoD).
• Pros: Access to consultants who know specifically about PCS moves, MSRRA, and CZTE. TurboTax free for military covers filing, but MilTax covers strategy.
• Cons: Interface is clunkier than TurboTax.

TurboTax Military:

• Cost: Free for Junior Enlisted; often paid for Officers or if you have diverse investments.
• Pros: Slick interface.
• Cons: Automated prompts might miss niche military deductions (like unreimbursed moving expenses for specific orders).

The MSRRA Trap

The Military Spouses Residency Relief Act (MSRRA) allows a non-military spouse to keep the same state of residence as the service member. This is huge. If you move to Virginia, you don’t necessarily have to pay Virginia income tax. Generic software often defaults to “Where do you live?” -> “Virginia” -> “Pay Tax.” You have to override it. MilTax pros know this inherently. TurboTax requires you to know it first.

For military families, MilTax or a specialized EA is often the safer strategic bet.

TSP Strategies Filing Software Won’t Suggest

The Thrift Savings Plan is one of the best retirement vehicles available — low fees, employer matching, and both Traditional and Roth options. But neither TurboTax nor MilTax will tell you how to optimize it:

• Traditional vs. Roth TSP: If you’re in a low tax bracket (common for junior enlisted), Roth contributions are almost always better. You pay taxes at a low rate now and withdraw tax-free later.
• Contribution limits: TSP follows the same 401(k) limits — $23,500 in 2025, $24,500 in 2026 (plus catch-up contributions at age 50+).
• Rollovers after separation: When you leave service, you can roll your TSP into an IRA for broader investment options — or keep it in TSP for low fees.

The Combat Zone Roth Conversion Window

This is the single most valuable military tax opportunity that filing software never mentions. When deployed to a combat zone:

• Your income is tax-exempt under the Combat Zone Tax Exclusion (CZTE)
• Your marginal tax rate drops dramatically — potentially to 0%
• This creates a window to convert Traditional TSP or IRA balances to Roth at little or no tax cost

A service member with $50,000 in Traditional TSP who converts during a combat zone deployment could save $10,000+ in lifetime taxes. TurboTax will never suggest this — it only records what happened after the fact.

Other Military Tax Opportunities to Explore

• State income tax savings: Many service members can maintain residency in a no-income-tax state (FL, TX, NV, WA) regardless of where they’re stationed
• Moving expenses: While most taxpayers lost this deduction under TCJA, active-duty military can still deduct unreimbursed moving expenses for PCS orders
• Earned Income Tax Credit: Junior enlisted with families may qualify — and can elect to include or exclude combat pay in the calculation, whichever is more beneficial
• Education credits: GI Bill benefits are tax-free, and tuition assistance may still leave room for the American Opportunity Credit
