There is no set dollar figure and no federal formula for how much alimony a military wife gets. The amount is decided by the state court handling the divorce, applying that state’s alimony statutes to the couple’s specific finances. What sets military cases apart is the income side of the equation: a service member’s real compensation includes tax-free allowances and special pays on top of base pay, and family courts count all of it. Federal law then caps how much of that paycheck can actually be collected once an order is in place.
Two courts in two states, looking at the same 15-year marriage, can reach very different answers. One might order long-term support; another might order a few years of rehabilitative payments and nothing more. The state’s law and the judge’s discretion drive the number.
What State Courts Weigh
Every state uses a similar core list of factors: length of the marriage, each spouse’s income and earning capacity, the marital standard of living, age, health, and one spouse’s need measured against the other’s ability to pay. Those apply the same way whether the paying spouse wears a uniform or not.
Military marriages add a layer courts take seriously. Frequent PCS moves are hard on a spouse’s career. Someone who relocated every two or three years often has a fractured resume, employment gaps, and few professional contacts in any single job market. Judges recognize that those sacrifices made the service member’s career possible, and that recognition shows up in both the amount and the duration of support. A spouse who spent 18 years as the primary caregiver during repeated deployments while the service member advanced in rank is in a very different position from a spouse leaving a short marriage where both partners worked continuously.
Rehabilitative alimony is common when the non-military spouse needs time and money to build or rebuild a career; it funds education or training and runs for a set number of years. For long marriages with limited earning potential on the non-military side, some states still award indefinite support, though many are moving away from truly permanent alimony.
What Counts as the Service Member’s Income
This is where military cases get interesting, and where paying spouses are often caught off guard. Total military compensation is significantly higher than base pay alone, and family courts across the country include the non-taxable allowances when calculating income available for support.
The two biggest additions are the Basic Allowance for Housing (BAH) and the Basic Allowance for Subsistence (BAS). BAH varies by rank, location, and dependent status. BAS covers food. Both are exempt from federal income tax, but family courts treat them as income because they reduce out-of-pocket living costs and effectively raise disposable income. A service member stationed in a high-cost area might receive $3,000 or more per month in BAH on top of base pay, and every dollar of it gets counted.
Courts may also factor in special and incentive pays: flight pay, hazardous duty pay, sea pay, and deployment-related bonuses. If a particular special pay has been a consistent part of the service member’s earnings over several years, a court is more likely to include it in the income calculation even though it could theoretically end.
VA Disability Compensation
VA disability sits in a legal gray area worth understanding. Federal law bars state courts from dividing VA disability compensation as marital property. But the U.S. Supreme Court held in Rose v. Rose (1987) that VA disability benefits can and should be considered as income when a court decides how much support a spouse needs and what the veteran can afford to pay. So a court cannot hand the former spouse a percentage of the disability check as property, but it can set a higher alimony amount after accounting for that income.
When a service member waives a portion of retired pay to receive VA disability instead, the retired pay pool available for division shrinks. Federal law does allow garnishment of VA disability payments for alimony and child support, but only when those payments replaced waived retired pay. That garnishment authority comes from 42 U.S.C. § 659, which subjects certain federal payments to withholding for support obligations.1Office of the Law Revision Counsel. 42 USC 659 Consent by United States to Income Withholding, Garnishment, and Similar Proceedings for Enforcement of Child Support and Alimony Obligations
Federal Caps on What Can Be Garnished
Once a court orders alimony, the Consumer Credit Protection Act sets hard ceilings on what can be pulled from the service member’s disposable earnings. These apply to military pay just as they apply to civilian wages.2Defense Finance and Accounting Service. Garnishment Pay Amount The applicable cap depends on whether the service member supports other dependents and whether back payments are owed:
- 50% of disposable earnings if the service member supports a current spouse or child and has no arrears
- 55% if the service member supports a current spouse or child and has arrears
- 60% if the service member has no other dependents and no arrears
- 65% if the service member has no other dependents and has arrears
These percentages only come into play when the full ordered amount exceeds what can be paid within the cap. If the ordered alimony fits within disposable earnings, DFAS deducts the full amount.3Office of the Law Revision Counsel. 15 USC 1673 Restriction on Garnishment
Interim Support Before Any Court Order
Divorce proceedings take months. A spouse may need money right away. Each military branch has its own interim family support rule that applies before any court order exists. These payments are not alimony, but they function as a financial floor that commanding officers can enforce.
The rules vary by service:
- Army: Under AR 608-99, a soldier pays interim support equal to BAH divided by the number of supported family members, plus an “enhanced” payment of 25% of the BAH rate to the non-military spouse.4U.S. Army. Army Family Support Requirements Per AR 608-99
- Navy: Under MILPERSMAN 1754-030, support for a spouse alone is one-third of gross pay (base pay plus BAH). For a spouse and one child, one-half. For a spouse and two or more children, three-fifths.5MyNavy HR. MILPERSMAN 1754-030 Support of Family Members
- Marine Corps: Under MARADMIN 126/18, a Marine pays a pro-rata share of BAH divided by the total number of family members (including the Marine). A spouse alone receives half of BAH; the fraction decreases as dependents grow.6United States Marine Corps. Financial Support of Family Members
- Air Force: AFI 36-2906 does not set dollar amounts. Commanders cannot order support payments, but they can take administrative or disciplinary action against a member who fails to support family and can reduce the member’s BAH from the with-dependents rate to the single rate.7U.S. Army (Installation Management Command). Family Support in the Air Force
These interim obligations end once a court issues a support order or the spouses sign a written agreement. They are an administrative backstop, not a substitute for a court order. The Navy’s regulation states explicitly that its scale is not intended as a basis for any judicial proceeding.5MyNavy HR. MILPERSMAN 1754-030 Support of Family Members If a service member refuses to provide any support during a pending divorce, the spouse can file a complaint with the commanding officer and trigger these requirements.
Retired Pay, the 10/10 Rule, and the Combined Cap
Retired pay division is technically separate from alimony, but the two come from the same paycheck and often move together in negotiations. The Uniformed Services Former Spouses’ Protection Act authorizes state courts to divide military retired pay as marital property and gives former spouses a way to receive payments directly from DFAS.8Defense Finance and Accounting Service. Former Spouse Protection Act
USFSPA caps direct payments of retired pay as property at 50% of the member’s disposable retired pay. When a former spouse also has a support order (alimony or child support) enforced through DFAS, the combined total can reach up to 65%.9Defense Finance and Accounting Service. Former Spouses Protection Act Frequently Asked Questions That 65% is the absolute ceiling under 10 U.S.C. § 1408.10Office of the Law Revision Counsel. 10 USC 1408 Payment of Retired Pay in Compliance With Court Orders
The commonly cited “10/10 Rule” affects the payment method, not entitlement. If the marriage lasted at least 10 years and overlapped with at least 10 years of creditable service, the former spouse can apply to DFAS for direct payment of the awarded share of retired pay.9Defense Finance and Accounting Service. Former Spouses Protection Act Frequently Asked Questions Falling short of the 10/10 overlap does not erase the right to a share of retired pay; it just means the service member must pay directly, which makes enforcement harder.
The 20/20/20 Rule Is About Benefits, Not the Amount
The 20/20/20 Rule does not affect how alimony is calculated. It determines eligibility for military benefits after divorce, specifically TRICARE health coverage, commissary and exchange access, and related privileges. Three conditions must all be met: 20 years of marriage, 20 years of creditable service, and a full 20-year overlap between the two.11TRICARE. Former Spouses A former spouse meeting the threshold becomes eligible for TRICARE as their own sponsor.12Joint Base Andrews. Former Spouses Rights
Losing TRICARE is a real financial hit, so the 20/20/20 threshold can indirectly influence alimony. A former spouse who misses the cutoff by a year or two may push for higher alimony to cover private health insurance. Judges are generally aware of that dynamic even in states where the rule is not a statutory factor.
Tax Treatment
For any divorce or separation agreement executed after December 31, 2018, alimony is not deductible by the payer and not taxable income to the recipient.13IRS. Topic No. 452 Alimony and Separate Maintenance The rule, enacted under the Tax Cuts and Jobs Act, applies to military and civilian divorces alike. Older agreements later modified follow the same treatment if the modification expressly adopts the new rule.14IRS. Publication 504, Divorced or Separated Individuals
For military families, this stacks with the tax-advantaged nature of the allowances. BAH and BAS are not subject to federal income tax, and alimony received is not taxable either, so the recipient’s total tax burden on support is generally lower than in a comparable civilian situation. The service member cannot deduct payments, which means the true after-tax cost of paying alimony is dollar-for-dollar.
Where the Case Is Filed and Why It Can Take Time
Filing for divorce as a military family is more complicated than walking into the nearest courthouse. Military families move frequently under PCS orders, and legal residence often differs from the current duty station. A service member does not automatically become a resident of a new state simply by being stationed there. Establishing residency typically requires affirmative steps like registering to vote, obtaining a local driver’s license, or filing a DD Form 2058 to change the state of legal residence.
A military divorce can generally be filed in one of three places: the state where the service member claims legal residence, the state where the non-military spouse lives, or the state where the service member is stationed if residency requirements are met. Where you file can significantly affect the alimony outcome because each state applies its own law.
The Servicemembers Civil Relief Act adds another wrinkle. If a service member cannot participate in proceedings because of military duties or deployment, the SCRA allows a stay, typically lasting at least 90 days, with extensions available for continued military necessity.15Office of the Law Revision Counsel. 50 USC 3932 Stay of Proceedings When Servicemember Has Notice Courts also cannot enter a default judgment against a service member who fails to appear due to service without first appointing an attorney to protect their interests. For the non-military spouse, that can mean significant delays before any permanent alimony order is issued, which is exactly why the branch interim support rules matter.
