Frequently Asked Questions

What is Family Separation Allowance?

FSA-II pays $250/month to a service member with dependents who is separated from family for 30+ continuous days due to military orders (deployment, sea duty, unaccompanied tour).

When does the 30-day clock start?

The clock starts on the first day of separation; once you cross 30 continuous days, FSA is payable back to day 1. Brief returns home (under 30 days) usually do not break continuity for sea-duty members.

Are dual-military members eligible?

Yes, FSA-II can be paid to both members in a dual-military marriage if both are separated by military orders and meet the rules - but only one parent can claim it as the “FSA-with-dependents” member when children are involved.

Is FSA taxable?

FSA is taxable income (unlike BAH/BAS), except in combat-zone tax-exclusion months. The calculator does not deduct taxes; consult your LES and finance office for exact net pay.

How This Calculator Works

Family Separation Allowance (FSA) is a flat $250/month tax-free allowance paid to service members with dependents who are separated from those dependents for more than 30 continuous days because of military orders. The statutory rate has been $250/month since the 2020 NDAA increase. FSA exists to partially offset the increased household costs that arise when a service member is away from family - duplicate communications expenses, paid childcare normally covered by the absent spouse, additional travel for the remaining parent, and so on. This calculator estimates daily, monthly, and total FSA for a given separation length and confirms eligibility against the 30-day threshold and dependency requirement. Estimates only; verify with your finance office.

Formula / Method

Total FSA = $250 ÷ 30 × days_separated for the period (once the 30-day trigger is met). Once eligibility is established on day 31, the allowance back-pays from day 1 of separation, so a 32-day deployment pays 32 × $8.33 = $266.67 total - not just two days of pro-rated payment. Three flavors exist: FSA-R (Restricted, dependents not authorized to accompany), FSA-S (member on Sea Duty 30+ days), and FSA-T (member on TDY/temporary additional duty 30+ days). All three pay the same $250/month statutory rate and cannot be stacked - only one type per month per member regardless of overlap.

Worked Example

An Army E-5 deploys to Iraq for 120 days. He has a spouse and one child stateside. Eligibility: yes (has dependents, separated by orders, ≥ 30 days). FSA-T applies. Daily rate = $250 ÷ 30 = $8.33. Total over 120 days = 120 × $8.33 = $1,000.00, equivalent to 4 full months × $250. The full $1,000 is tax-free and shows on the LES as "FSA" in the entitlements column. Combined with any Hostile Fire Pay/Imminent Danger Pay ($225/month) and the Combat Zone Tax Exclusion that may apply, deployment income often exceeds garrison take-home by 30–50% even before re-enlistment or hardship bonuses.

Common Mistakes

Assuming members without dependents qualify - FSA is dependency-based; single members with no qualifying dependents are not eligible regardless of separation length.

Trying to draw FSA when both spouses are dual-military and one is home - the rule is that one spouse must remain physically with any qualifying dependents; if no dependents, no FSA.

Confusing FSA with Hostile Fire Pay / Imminent Danger Pay - they can both be earned in the same month and stack to roughly $475/month plus CZTE for deployed members.

Forgetting that FSA stops the day the member returns to the same location as dependents, even mid-month - payment is prorated to the day of reunion.

Believing FSA is taxable - it is excluded from gross income under 37 U.S.C. § 427.

Tips & FAQ

Q: Does a TDY school of 35 days qualify? A: Yes, if the member has dependents and is geographically separated from them by orders for the full 35 days. Q: What if I take 10 days of leave home during a 90-day TDY? A: FSA pauses for the days the member is physically with dependents and resumes when separation resumes - the 30-day clock does NOT reset, but paid days are reduced. Q: Are dual-military couples with no children eligible when both deploy? A: Generally no - without qualifying dependents the entitlement does not arise, even for dual-mil couples. Q: Does FSA count for TSP contributions or for retirement High-3? A: It counts as compensation for TSP purposes but NOT for the High-3 retirement calculation. Always confirm current FSA rates and eligibility with the DoD FMR Volume 7A Chapter 27 and your installation finance office before relying on these figures.
