Sell Your Leave or Take Terminal Leave? The Math, the 60-Day Career Cap, and the October 1 Deadline

Quick answer: Taking the leave is usually worth more per day than selling it, because sold leave is paid on basic pay only — no BAH, no BAS, no special pays. On top of that, you can only ever be paid for 60 days of leave in an entire career, and days you sold at a past reenlistment already came out of that 60. And the part almost nobody plans for: leave above the carryover ceiling is forfeited on October 1, not cashed out. If you are sitting on a big balance and doing nothing, the default outcome is that you lose it for free.

This post is aimed at people whose separation, ETS, or retirement date falls after October 1, 2026, because that is where the deadline in the title actually bites. If you are separating before then, most of the math below still applies to you, but the forfeiture timing does not necessarily work the same way — ask finance directly rather than assuming.

If you are still trying to figure out how terminal leave fits alongside SkillBridge and permissive TDY on the calendar, read Terminal Leave vs SkillBridge vs PTDY first. This post is narrower: it is about what a leave day is worth, and how to avoid throwing days away.

The Three Things That Happen to Unused Leave

Every leave day you have accrued ends up in one of exactly three buckets. That is it.

1. You take it. Ordinary leave, including terminal leave at the end of service. You are still a service member on those days.
2. You sell it. A lump-sum payment at basic pay only, subject to a 60-day lifetime cap.
3. You forfeit it. It evaporates at the end of the fiscal year. No payment, no carryover, no notification.

Most briefings cover options one and two and skip straight past three. That is backwards, because forfeiture is the default. It is what happens when you do not make a decision. Options one and two require you to act; option three requires nothing from you except a calendar flipping over to October.

For reference, you accrue 2.5 days of leave per month, which is 30 days a year, per Military OneSource. Terminal leave is not a special category of leave — it is regular chargeable leave that happens to fall at the end of your service, and like any other leave it is granted at your command's discretion.

How Much a Leave Day Is Actually Worth

This is where people talk themselves into bad decisions, usually because "I'll just sell it and take the check" sounds decisive and adult. It is worth running the actual numbers instead.

Sold leave: basic pay only, no BAH or BAS

The controlling statute is 37 U.S.C. § 501. Subsection (b) bases the payment on "the basic pay to which the member was entitled on the date of discharge." Allowances were removed from that calculation by the 1976 amendments to the statute.

Plain English: a sold leave day pays you one day of basic pay. Your housing allowance is not in there. Your subsistence allowance is not in there. Special and incentive pays are not in there. If a meaningful chunk of your monthly gross is allowances — and for most people it is — then selling a day gets you noticeably less than a day.

Terminal leave: you are still on active duty

Terminal leave is chargeable leave, which means you have not separated yet. Your separation date does not move because you went on leave; you are simply not showing up to work. The general rule that follows from this is that your pay and allowances continue as normal during terminal leave, which is why "take the leave" usually beats "sell the leave" on a per-day basis.

I am deliberately calling that the general rule rather than quoting a regulation at you. The pay-side authority for exactly what continues during terminal leave lives in the DoD Financial Management Regulation (DoD 7000.14-R), and I could not verify the current citation to the standard I hold myself to on this site. So: treat "full pay and allowances continue on terminal leave" as the normal expectation, and confirm your specific situation with finance, especially if you draw special or incentive pays, are in a variable housing situation, or are moving mid-leave.

A worked example (one E-6, one O-4)

Below are two illustrations. The dollar figures are deliberately rounded placeholders, not pay-table numbers. I am not going to publish precise 2026 basic pay amounts I have not verified against the current table, because a stale number in a blog post is exactly how people make five-figure decisions on bad data. Go pull the current military pay table and your own LES, then redo this with your real figures. The structure of the math is the point.

Military pay math runs on 30-day months, so a day of basic pay is roughly monthly basic pay divided by 30.

Same shape both times, different magnitudes: the taken day runs about 50% above the sold day in the E-6 illustration and about a third above it in the O-4 illustration. The gap scales with how much of your compensation is allowances. Someone in a high-BAH location loses more by selling. Someone in government quarters with a small housing allowance loses less. Run yours.

There is also a non-dollar side to the taken day. On terminal leave you are still on active duty, which means you are still inside the military health system, still accruing time toward your pay date and retirement calculation, and still holding an ID card that works. Those things end at your separation date, not at the end of a check.

Taxes on a sell-back payment

A leave sell-back is a lump-sum wage payment, and it is taxable. Lump sums like this are commonly withheld at the federal supplemental-wage rate, which is 22% for 2026 per IRS Publication 15 (the rate rises to 37% on supplemental wages above $1 million in a year, which is not going to be your problem).

Two honest caveats. First, the 22% figure is the IRS supplemental rate; I am not asserting that your defense finance office applies that specific rate to your specific payment. The only place you will see what actually got withheld is your final leave and earnings statement. Read it instead of guessing. Second, withholding is not the same as tax owed — it is an estimate that gets trued up when you file. If too much came out, you get it back the following spring, which is not the same as having it in March.

Also in play: Social Security and Medicare (FICA) taxes, and state income tax, which depends entirely on your state of legal residence. Some states do not tax military pay at all. Others will. That is a conversation for a tax preparer, not a blog post.

The 60-Day Career Cap Most People Learn About Too Late

Here is the sentence that surprises people at the finance counter: the 60-day sell-back limit is a lifetime limit, not a per-separation limit.

37 U.S.C. § 501(f) says the number of days for which payment may be made "may not exceed sixty, less the number of days for which payment has been previously made under such subsections after February 9, 1976." Read that clause slowly. Every day you have ever been paid for since February 1976 is subtracted from the 60 you think you have.

So if you sold 20 days at a reenlistment in 2014 because you needed cash for a move, you walk into retirement with 40 sellable days, not 60. Nobody flags this for you in advance. It shows up as a smaller-than-expected number on a final pay calculation.

One narrow exception, and then I will leave it alone: under § 501(b)(5), the 60-day career limit does not apply to leave accrued by a reserve component member (or a Space Force member in space force active status not on sustained duty) while serving on active duty in support of a contingency operation — it is an exception for that leave, not a blanket exemption for the member. Ordinary leave a reservist accrued outside that duty is still subject to the 60-day career cap. Separately, § 501(d) sets aside the 60-day limit for settlement payments when a member dies. If any of that describes your situation, it is a finance-office conversation, not a blog-post conversation.

The October 1 Cliff

This is the part that costs people money silently.

The normal rule: above 60 days is gone on October 1

The standard carryover ceiling is 60 days, and leave above that ceiling is forfeited at the end of the fiscal year, per myAirForceBenefits. Since you accrue 30 days a year and the ceiling is 60, it is entirely possible to hit the wall in two years of not taking leave.

Note the mechanic: it is forfeited. Not paid. Not rolled over. Not converted into anything. The days simply stop existing on October 1.

Special Leave Accrual: how you get to 90, and the two-fiscal-year window

Special Leave Accrual (SLA) is the relief valve for people whose duty genuinely prevented them from using leave. It raises your ceiling above 60. Qualifying circumstances include service in a hostile fire or imminent danger pay area for 120 or more continuous days, along with other designated circumstances (see myAirForceBenefits and Military OneSource).

The current ceiling with SLA is 90 days total: 60 ordinary plus up to 30 SLA. Going forward, 90 is the most you can carry into a new fiscal year. The only members legitimately sitting above 90 today are the ones grandfathered when the ceiling dropped — and that ends this year. See below.

That last point is recent history. The FY23 NDAA amended 10 U.S.C. § 701 and did two things:

• Cut the ceiling from 120 days (60 annual + 60 SLA) down to 90 days (60 annual + 30 SLA).
• Shortened how long you can hold SLA leave from three fiscal years to two after the fiscal year in which the qualifying duty ended.

The shortened retention window is the sleeper problem. SLA days are not permanent. They expire, and the expiration is tied to when your qualifying duty ended — not to when you noticed.

The September 30, 2026 deadline

When the ceiling dropped, members who already had approved SLA balances above 90 days were not stripped overnight. They were allowed to keep carrying the excess. But that grace had an end date, and the end date is now.

Sources on the wind-down: Military OneSource and Military Times.

If you have been carrying a fat balance since a 2021 or 2022 deployment and telling yourself you will "use it when things slow down," this is the year that assumption stops being free.

Enlisted have a one-time 30-day out. Officers do not.

There is one escape hatch, and it is not available to everyone. Per myAirForceBenefits: enlisted members with more than 90 days accrued may, once in a career, sell back up to 30 days of leave in excess of the 90-day limit.

Two strings attached, and both matter:

• It counts against your 60-day career sell-back cap. Using 30 days here leaves you 30 for separation or retirement — and less than that if you have sold leave before.
• It is once. Ever. Not once per enlistment, not once per fiscal year.

Officers facing forfeiture do not have this option. If you are an officer sitting above the ceiling, your choices are to burn the leave or lose it. That is not a rhetorical framing; it is the actual menu.

The Army says the same thing in essentially identical wording on its myArmyBenefits leave page for Army Reserve Soldiers on active duty — and notably, that page describes the sell-back as counting against "the 60-days active duty Soldiers may sell during their military career," which is not Reserve-specific language. So this is not an Air Force quirk. One caveat anyway: both of those are service-published benefits pages, not the statute itself. Have your own finance office confirm how it is implemented for you before you submit anything.

If You Separate After October 1, Here Is the Decision Tree

Find your balance, then work the branch. Do this with your projected balance at the relevant date, not today's number — you are still earning 2.5 days a month while you think about it.

The practical version for everyone: get your real numbers (current balance, projected balance at separation, days of career sell-back already used, SLA expiration date), then decide. Four data points. Finance can give you all four in one visit.

How This Interacts With SkillBridge and PTDY

Short version, because there is a whole post on this: your leave balance and the final-180-days calendar are two separate constraints that both have to be satisfied.

Terminal leave and SkillBridge cannot overlap. SkillBridge requires you to be on active duty orders performing the fellowship; terminal leave means you are on leave and not performing duty. Every day you spend on SkillBridge is a day you are not drawing down your leave balance. So if you are carrying a big balance and you also want a long SkillBridge, those two goals are in direct competition for the same weeks.

Permissive TDY does not consume leave days at all, which sounds like a win and mostly is — but PTDY days still occupy calendar space before your separation date. They do not help you burn down a leave balance. If forfeiture is your problem, PTDY is not your solution.

The full breakdown of how these blocks compete, with worked timelines, is in Terminal Leave vs SkillBridge vs PTDY: How the Final 180 Days Actually Work. If you are carrying more than 60 days of leave and planning a long SkillBridge, read that before you commit to either.

Mistakes That Cost Real Money

1. Assuming excess leave gets cashed out at separation. It does not. Days above the ceiling are forfeited on September 30, and days above your remaining career sell-back cap are not payable either. This is the expensive one, and it is expensive precisely because it requires no action to happen.

2. Not checking prior sell-backs. The 60 days is a lifetime figure under § 501(f), reduced by everything paid since February 9, 1976. People plan around 60, then find out at final pay that a reenlistment sell-back a decade ago left them 35. Ask before you plan.

3. Not knowing your SLA expiration date. SLA leave is retained for two fiscal years after the fiscal year in which the qualifying duty ended. That is a specific date for your specific deployment. "I have SLA" is not a plan; "my SLA expires on X" is.

4. Not confirming command approval for terminal leave. Terminal leave is ordinary chargeable leave, which means it is granted at command discretion. It is usually approved, but "usually" is doing work in that sentence. If your plan to avoid forfeiting 40 days depends on 40 days of approved leave, get the approval in writing before you tell a civilian employer your start date.

5. Forgetting that benefits end at your separation date, not the end of your leave. Terminal leave sits before the separation date, so it does not extend anything. TRICARE coverage as an active duty family, BAH, commissary access, your ID card privileges — those are tied to the separation date. Selling leave instead of taking it does not shorten your coverage, and taking leave does not extend it. What changes is how much money you get and how you spend those weeks. For what happens on the other side of that date, see Pay, Benefits, and Healthcare After Military Separation.

6. Waiting until 60 days out to start the conversation. If you need to burn 45 days of leave and your unit is short-staffed, you cannot manufacture that window in the last two months. This decision belongs at 9 to 12 months out, alongside the rest of your out-processing. The separation checklist puts it in sequence with everything else.

Frequently Asked Questions

Is it better to sell back leave or take terminal leave?

For most people, taking the leave is worth more per day. Sold leave is paid on basic pay only — 37 U.S.C. 501(b) ties the payment to the basic pay you were entitled to on your date of discharge, and allowances are not part of that calculation. Terminal leave is ordinary chargeable leave, so as a general rule you remain on active duty and keep your normal pay and allowances during it. Selling wins in narrower cases: your command will not approve the leave, you already have a civilian start date you refuse to move, or you would otherwise forfeit the days. Confirm your own numbers with your finance office before you decide.

How many days of leave can I sell back when I separate or retire?

Sixty days total, for your entire career — not sixty days per separation. 37 U.S.C. 501(f) caps the number of days for which payment may be made at sixty, less the number of days for which payment has previously been made after February 9, 1976. If you sold 20 days at a reenlistment in 2014, you have 40 left at retirement, not 60. Pull your own history before you plan around a number, because your leave and earnings statement shows your current balance, not what you already cashed out years ago. One narrow exception: the 60-day career limit does not apply to leave accrued by a reserve component member while serving on active duty in support of a contingency operation.

Is sold-back leave paid at full pay with BAH and BAS?

No. Sold leave is paid on basic pay only. 37 U.S.C. 501(b) bases the payment on the basic pay you were entitled to on the date of discharge, and the 1976 amendments removed allowances from that calculation. BAH, BAS, and special or incentive pays are not part of a leave sell-back payment. This is the single biggest reason a day taken as leave is usually worth more than a day sold.

How is leave sell-back taxed?

A lump-sum leave payment is taxable wages, and lump-sum payments like this are commonly withheld at the federal supplemental-wage rate, which is 22 percent for 2026 per IRS Publication 15 (37 percent on supplemental wages above $1 million in a year). Social Security and Medicare taxes also apply, and state tax treatment varies by your state of legal residence. Withholding is not the same thing as what you owe — it is an estimate that gets reconciled on your tax return. The only place you will see what was actually withheld from your payment is your final leave and earnings statement, so read it.

What happens to leave I don't use before October 1?

Ordinary leave above the 60-day carryover ceiling is forfeited at the end of the fiscal year. It is not paid out, it is not carried forward, and nobody sends you a warning email. This is the single most expensive misunderstanding in this whole subject: people assume excess leave converts to cash at separation. It does not. Forfeiture is the default outcome when nobody plans, and the deadline is September 30.

What is Special Leave Accrual, and what changes on September 30, 2026?

Special Leave Accrual (SLA) lets you carry leave above the normal 60-day ceiling when duty made it impossible to use — for example, service in a hostile fire or imminent danger pay area for 120 or more continuous days, or other designated circumstances. The current ceiling is 90 days total: 60 ordinary plus up to 30 SLA. That 90 is the statutory maximum carryover. The FY23 NDAA lowered the ceiling from 120 days to 90 and shortened SLA retention from three fiscal years to two after the fiscal year in which the qualifying duty ended. Members whose approved SLA balance was above 90 days as of December 31, 2022 were allowed to keep carrying the excess, but any SLA leave exceeding 90 days on or before September 30, 2026 is forfeited. In practical terms: if you are sitting on more than 90 days, the amount above 90 is gone on October 1, 2026 unless you use it or, if you are enlisted, use the one-time 30-day sell-back.

Final Thoughts

Leave is the one piece of compensation you accrued day by day, for years, and it is also the piece most likely to quietly disappear. Not because anyone is trying to take it from you, but because the forfeiture rule works automatically and the sell-back rules are written in a statute nobody reads until the week they need it.

The decision itself is not complicated. A taken day is generally worth more than a sold day because allowances are in the first number and not the second. You get 60 paid days in a career, total, minus whatever you already used. And anything above the ceiling on September 30 is gone.

What is complicated is finding out your actual numbers, and that is a single trip to finance: current balance, projected balance at separation, career sell-back days already used, and SLA expiration date. Ask for all four in one conversation. Then decide with real numbers instead of the version of the rules that circulated in your shop.

If you take nothing else from this: October 1 does not care whether anyone briefed you.
