Military Couples Financial Planning: TSP, SBP, VA Loans, and Life After Service

Military families deal with financial planning dimensions that civilian advisors often mishandle: non-taxable allowances, a defined-benefit pension that requires an election at retirement, group life insurance that vanishes at separation, a home loan benefit most people underuse, and a military spouse whose career gaps create a retirement savings hole that compounds for decades. This guide covers each.

Military pay structure: what counts and what doesn't

Military compensation is more complicated than a civilian paycheck, and understanding the taxable vs. non-taxable breakdown matters for nearly every planning decision — Roth eligibility, IRMAA exposure, retirement projections, and mortgage applications.

• Basic Pay: Taxable. The base salary that drives TSP contributions, SBP calculations, and most retirement math. Publicly published by grade and years of service.
• Basic Allowance for Housing (BAH): Not federally taxed. Based on duty station zip code and dependency status (with vs. without dependents). For a married O-4 in a high-cost area, BAH can exceed $3,000/month — a $36,000/year non-taxable benefit. BAH does not count toward AGI, which matters for Roth IRA eligibility and ACA subsidy cliffs.
• Basic Allowance for Subsistence (BAS): Not federally taxed. Relatively small ($470.76/mo for officers, $323.87/mo for enlisted in 2026), but still non-taxable income.
• Combat Zone Tax Exclusion (CZTE): All pay earned while serving in a designated combat zone is excluded from federal income tax. This matters most for Roth IRA: even though combat pay is excluded from income for tax purposes, it counts as "earned income" for IRA contribution purposes — meaning a deployed servicemember can fund a Roth IRA using combat pay, paying zero tax on the contribution and zero tax on future growth.

TSP: the military 401(k)

The Thrift Savings Plan is structurally identical to a 401(k). The same contribution limits apply, and the investment options (C, S, I, F, G Funds, and L-Fund lifecycle funds) span domestic stocks, international stocks, bonds, and a stable government securities fund.

Roth TSP vs. traditional TSP for military couples

The Roth vs. traditional TSP decision follows the same logic as for civilians: pay taxes now (Roth) or defer them (traditional). For military couples, several factors shift the math:

• Non-taxable allowances suppress your effective tax rate. A household with $90,000 base pay + $30,000 BAH has a federal tax bill on only $90,000. This pushes the Roth breakeven further in Roth's favor — you're paying tax at artificially low rates today.
• Combat zone contributions can go to Roth TSP tax-free. Deploying in a combat zone? Roth TSP contributions from combat pay cost zero federal tax, and all future growth is also tax-free. The annual additions limit ($72,000) allows much higher total contributions in a combat zone year than the standard $24,500 cap.
• Military pension creates future taxable income. A servicemember retiring after 20 years under the Blended Retirement System receives a pension (taxable income) for life. If they also have large traditional TSP balances triggering RMDs, the combination can push them into higher brackets in retirement. Roth TSP now reduces that pressure.

For a military spouse: no TSP access unless also employed by the federal government or military. See the military spouse section below.

Blended Retirement System vs. Legacy "High-3" pension

If your servicemember entered DOD on or after January 1, 2018, they are in the Blended Retirement System (BRS). If they entered before 2018 and did not opt in, they are under the Legacy "High-3" system. This is the most important retirement planning distinction in military financial planning.

The math at 20 years: Under Legacy, a servicemember retiring at O-5 (LTC/CDR/Lt Col) with a high-3 average of $9,000/month receives a $4,500/month pension for life. Under BRS, the same servicemember receives $3,600/month — $900/month less, or $10,800/year. The BRS servicemember needs their TSP balance to generate enough income to make up that gap.

BRS matching is valuable — but only if you contribute. BRS servicemembers who don't contribute at least 5% of base pay to TSP are forfeiting free matching money (up to 4% of base pay + 1% automatic). The earliest years of service are when the matching has the longest time to compound.

The Survivor Benefit Plan (SBP): the retirement decision that affects both spouses for life

At military retirement, the servicemember must decide whether to elect the Survivor Benefit Plan. This is one of the most consequential financial decisions a military couple makes — and it requires both spouses' input.

How SBP works

• Cost: 6.5% of the base amount (elected coverage level, up to full retired pay).²
• Benefit: Upon the servicemember's death, the surviving spouse receives 55% of the elected base amount as a lifetime, inflation-indexed annuity.
• 2026 COLA: SBP payments increased 2.8% on December 1, 2025, matching the COLA applied to Social Security benefits.
• Break-even: At full coverage, the surviving spouse recoups all SBP premiums paid at roughly year 8–10 of survivor payments (depending on the elected base amount and COLA adjustments).
• Alternative structure: You can elect a lower base amount to reduce premiums. The minimum base is $300/month; coverage must be in the full coverage vs. reduced coverage vs. no coverage structure at election.

SBP vs. private life insurance — the comparison most advisors get wrong

A common argument for declining SBP: "buy term life insurance instead — it's cheaper." That argument has serious flaws for military couples:

• Term insurance expires, usually at 20- or 30-year policy term. A military spouse who lives to 85 after the servicemember dies at 65 may outlive a term policy by 20 years.
• SBP is inflation-indexed. A 2.8% COLA means the SBP payment roughly doubles every 25 years. A $3,500/month SBP payment in 2026 becomes ~$7,000/month by 2051 in nominal terms. Term insurance death benefits are fixed.
• SBP premiums are paid with pre-tax dollars (deducted from retired pay before taxes). A $500/month SBP premium costs roughly $375–$425 after tax for a retiree in the 22–24% bracket.

SBP may still not be the right choice for every couple — particularly if the spouse has independent substantial assets, if both are veterans (see VA Dependency and Indemnity Compensation interaction), or if health conditions make break-even timing unfavorable. The decision deserves detailed modeling, not a heuristic.

SBP and VA DIC offset — the widower's trap

If the servicemember dies of a service-connected cause, the surviving spouse may be eligible for VA Dependency and Indemnity Compensation (DIC). Historically, DIC payments reduced SBP payments dollar-for-dollar — a provision called the "widow's tax." The SBP-DIC Concurrent Receipt was phased in and fully implemented in 2023, eliminating the offset. Surviving spouses now receive both SBP and DIC in full.² If you were told years ago that DIC cancels SBP, that information is now outdated.

SGLI and FSGLI: life insurance while on active duty

Every servicemember is automatically enrolled in Servicemembers' Group Life Insurance (SGLI) at the maximum level unless they opt down.

The $26/month for $500,000 of coverage is extraordinarily cheap. For most active-duty servicemembers, holding maximum SGLI coverage is a straightforward decision. FSGLI is similarly cost-effective for younger spouses; premiums rise with age, but even at the top age band the cost is modest.³

What happens to SGLI at separation — VGLI and the conversion window

SGLI coverage ends 120 days after separation. Servicemembers have the option to convert to Veterans' Group Life Insurance (VGLI) — without a medical exam, regardless of health — within 240 days of separation (120-day free window + 120-day window with health questions). VGLI is age-rated and becomes expensive in older age bands; many veterans with good health can buy cheaper private term coverage. Those with health conditions that developed during service may find VGLI is the only option available.

The couples planning angle: If the separating servicemember has any service-connected health condition that makes private insurance expensive or unavailable, converting the full $500,000 to VGLI within the no-exam window is critical. Missing that window can leave the military spouse with a fraction of the coverage — or none at all.

VA home loan: the most underused couples benefit

Qualifying veterans and active-duty servicemembers are entitled to VA home loans, which eliminate the single largest barrier to homeownership: the down payment.

• No down payment required for borrowers with full entitlement (no prior VA loan, or prior VA loan fully paid off and entitlement restored).
• No private mortgage insurance (PMI), ever. On a $400,000 home with a conventional loan at less than 20% down, PMI typically costs $100–$200/month — $1,200–$2,400/year until you reach 20% equity.
• Competitive rates. VA loans typically carry interest rates 0.25–0.5% below conventional loans, because the VA guaranty reduces lender risk.
• 2026 conforming baseline: $832,750 (FHFA limit, applicable to standard VA purchases with partial entitlement). Full entitlement borrowers have no dollar ceiling on the zero-down benefit.⁴
• Funding fee: VA loans charge a one-time funding fee (1.25%–3.3% of the loan, depending on down payment and prior VA loan use). Veterans with a service-connected disability rating of 10% or higher are exempt from the funding fee — a $5,000–$10,000 savings on a typical purchase.

Couples strategy with the VA loan

Married couples can apply for a VA loan jointly (one veteran spouse + one civilian spouse) or with the veteran spouse only. The choice has trade-offs:

• Joint application: Both incomes are counted, which increases maximum loan size. But both credit scores are evaluated; if the civilian spouse has lower credit, the loan may be priced at a higher rate than the veteran-only application.
• Veteran-only application: Uses only the veteran's income and credit. May limit borrowing power but can produce a better rate if the civilian spouse's credit is a drag.

If the military couple has used their VA entitlement before (prior VA loan), entitlement can be restored by paying off the prior loan. Bonus entitlement also allows purchases above the standard limit in high-cost counties. A VA-specialty lender can model both scenarios and choose the optimal structure.

Military spouse financial planning: the career gap problem

Military spouses who follow their servicemember through multiple PCS moves often face career disruption that civilian advisors underestimate. The financial consequences compound:

• Retirement savings gap: A military spouse who works intermittently or part-time over 10–15 years of a military career may accumulate far less in employer retirement accounts than a continuous civilian peer. The lost compounding on $10,000/year in missed 401(k) contributions over 15 years at 7% is roughly $250,000 at retirement age.
• Social Security gap: SS benefits are based on 35 highest earning years. Gaps reduce the average. A military spouse with 10 years of low or zero earnings may have a meaningfully lower SS benefit than a continuously employed civilian peer — a difference worth modeling when the couple is estimating retirement income.
• Spousal IRA during career gaps: A non-working military spouse can still contribute to a spousal IRA ($7,500 in 2026, or $8,600 if age 50+) as long as the servicemember has earned income greater than the combined contribution amount. The servicemember's base pay (even if largely non-taxable due to allowances) satisfies this requirement. See our full Spousal IRA guide.
• Roth IRA during low-income PCS years: In years when the military spouse's income is low or zero, their Roth IRA eligibility is excellent — low current tax rate means the Roth advantage is maximized. Prioritizing Roth contributions in these windows compounds over time.

State income tax during PCS moves

The Military Spouses Residency Relief Act (MSRRA), as updated by the Veterans Benefits and Transition Act of 2018, allows a military spouse to elect to use the same state of domicile as the servicemember — even if the spouse earns income in a different state. This can avoid double taxation during a PCS move and may reduce state income tax for spouses who work remotely or are employed in a high-tax duty station state. Documentation matters: maintain clear records of the elected domicile and consistently file in that state.

TRICARE and healthcare transition

Active-duty families receive TRICARE coverage, which eliminates most out-of-pocket healthcare costs. What changes at retirement and separation requires planning:

• TRICARE Retired Reserve / TRICARE Select: Retirees with 20+ years of service retain TRICARE, but the coverage transitions from active-duty TRICARE (free) to TRICARE Select for Retirees (premium-based). In 2026, premiums are roughly $30–$60/month per person.
• TRICARE and Medicare at 65: Military retirees become eligible for Medicare at 65 and are required to enroll in Medicare Part B to keep TRICARE (it becomes TRICARE For Life, which wraps around Medicare as secondary coverage). The Medicare Part B premium ($202.90/month base in 2026, plus IRMAA if applicable) is now a new household expense.
• Separation (under 20 years): TRICARE ends 180 days after separation. The family needs a bridge: COBRA from a new employer's plan (if both spouses are transitioning simultaneously and the civilian spouse has employer coverage, that may be the bridge), ACA marketplace coverage, or immediate civilian employer coverage if the transition is immediate.

SCRA protections while deployed

The Servicemembers Civil Relief Act (SCRA) provides important financial protections during active-duty service. Key provisions couples should know:

• 6% interest rate cap on any debt incurred before entering active duty (mortgages, car loans, credit cards, student loans). To invoke the cap, the servicemember must send written notice and a copy of military orders to the lender. The cap lasts for the period of active service (and one year beyond for mortgages).⁵
• Lease termination: A servicemember on PCS orders or deployment can terminate a residential lease with 30 days' notice. This applies to both the servicemember and their co-signor spouse on the same lease.
• Foreclosure and eviction protection: Courts must pause civil proceedings (including foreclosure) for servicemembers who can demonstrate military service materially affects their ability to appear.
• Credit protection: Lenders cannot report reduced interest rate payments under SCRA as negative information to credit bureaus.

The SCRA caps apply only to pre-service debt — not debt taken out after entering active duty. A military couple who refinances their mortgage after the servicemember is already on active duty does not get the 6% cap on that refinanced loan.

Estate planning basics for active-duty couples

Active-duty couples have heightened estate planning urgency: one spouse may deploy to a combat zone with little notice. Basics that should be in place before any deployment:

• Military Power of Attorney: A durable POA allows the at-home spouse to manage finances, sell a car or home, and handle legal matters during deployment. Many installations have legal assistance offices that provide free POAs.
• SGLI beneficiary designation: SGLI pays to the designated beneficiary on file — not automatically to a spouse. Keep the designation current, especially after marriage, divorce, or the birth of a child.
• SGLI and trusts: If minor children are involved, naming a trust (vs. naming the children directly) avoids the need for a court-appointed guardian to manage the insurance proceeds. This requires an attorney but is worth doing before a deployment.
• SCRA civil court protection for estate proceedings: The SCRA can pause court proceedings involving a deployed servicemember, but proactive estate documents eliminate the need for court involvement.
• TSP beneficiary designation: Like IRA beneficiary designations, TSP beneficiary designations are independent of a will. Check them annually.
