The short answer: your CRSC effective date is set condition by condition. For each one it is the latest of three things — the first full month after your retirement, the first full month after the VA’s effective date of service connection for that condition, and the statutory floor that applies to you. A claim with four approved conditions can carry four different effective dates, and the money follows each one separately.
Statutory citations verified against 10 U.S.C. § 1413a and its enacting public laws, August 29, 2026.
Why this suddenly matters. Before Soto v. United States (June 12, 2025), the Barring Act capped CRSC back pay at six years. Your effective date rarely changed anything past that wall. With the cap gone — and DoD’s interim limits rescinded on May 14, 2026 — the effective date now sets the entire length of your retroactive period. It is frequently the largest single number in a CRSC case.
The rule, in one sentence
For each condition your board approves as combat-related, the effective date is the latest of:
- the first full month after your retirement date;
- the first full month after the VA’s effective date of service connection for that condition; and
- the statutory floor that applies to you.
“Latest of” is doing the work in that sentence. Whichever of the three is most recent is the one that controls. If you retired in 2011, the 2003 floor is irrelevant to you — your retirement date is later, so it wins. If the VA service-connected your tinnitus in 2019, that condition’s CRSC clock starts in 2019 no matter when you retired.
Why it’s per condition, not per claim
CRSC pays on the VA rating value of your combat-related conditions. The VA doesn’t service-connect everything at once — it grants conditions as it decides them, each with its own effective date, sometimes years apart. Because rule 2 above points at “that condition,” each approved condition inherits its own start date.
A worked example. Say a retiree left service in 2009 and the board later approves three conditions as combat-related:
| Condition | VA service-connected | CRSC effective date |
|---|---|---|
| Lumbar spine | 2010 | 2010 — SC date is later than retirement |
| Tinnitus | 2016 | 2016 — six years of back pay less than the back |
| PTSD | 2021 | 2021 — eleven years less than the back |
One retiree, one claim, three effective dates. A calculator that asks “when did you retire?” and multiplies from there will get all three of these wrong. So will a “pay chart” estimate that assumes your whole combat-related percentage was in place from day one — it wasn’t. Your combat-related rating grew as conditions were added, and each retro month is paid at the percentage you actually held that month.
The statutory floors — and the one everybody gets wrong
Three public laws set the floors. They are not tiers you choose from; only one applies to you.
June 1, 2003 — the program start
Public Law 107–314 § 636 created 10 U.S.C. § 1413a and directed it to take effect no later than 180 days after December 2, 2002. As originally written, § 1413a(c)(1) required at least 20 years of creditable service, or Reserve retired pay under § 12731. If you were a 20-year or Reserve retiree, this is your floor.
January 1, 2004 — the expansion
Public Law 108–136 § 642 broadened the combat-related definition and the non-regular retirement route, applying “to payments… for months beginning on or after January 1, 2004.”
January 1, 2008 — when the 20-year requirement fell
Public Law 110–181 § 641 struck the 20-year service requirement from § 1413a(c), effective January 1, 2008. That is the change that opened CRSC to retirees who had been shut out entirely.
Here is the part that is routinely stated wrong — including, until recently, on this website.
You will read that “January 1, 2008 is the floor for Chapter 61 retirees.” That is only half right. The 2008 amendment removed a service-length requirement, not a retirement-type one. So it applies to Chapter 61 medical retirees with fewer than 20 years of creditable service, who genuinely were not eligible for CRSC before 2008. A Chapter 61 retiree with 20 or more creditable years already qualified under the original 2003 law — their floor is June 1, 2003. Told the wrong one, a 22-year medical retiree could give up nearly five years of back pay without ever knowing it was there.
TERA retirees — those who took early retirement between 15 and 20 years during the drawdown — also came in on the 2008 change, for the same reason: they had retired pay but not 20 years.
What this means for your number
Three practical consequences.
Check your retirement length, not just your retirement type. “Chapter 61” on its own does not tell you your floor. Creditable years does. Your DD-214 has it.
Pull the effective date for every condition, not just the claim. Your VA decision letters carry a service-connection effective date per condition. Those dates, not your retirement date, drive most CRSC retro periods.
Expect the monthly amount to change across the retro period. Each retro month is paid at the rate table in effect that month and at the combat-related percentage you held that month. Both were lower in the past. Any estimate that multiplies today’s monthly figure by the whole period will come in high — on a ten-year retro, materially so. Our calculator steps each year down by the actual VA cost-of-living adjustment for exactly this reason.
Frequently asked questions
Does an earlier effective date mean more money automatically?
Not automatically. It means more months. What you receive for those months is still capped — by the retired pay you waived, by your combat-related percentage as it stood at the time, and for Chapter 61 retirees by longevity-earned pay. More months at a small monthly figure is still a smaller number than fewer months at a large one.
My board gave one effective date for the whole claim. Is that wrong?
Not necessarily. If every approved condition was service-connected before you retired, they can legitimately share a date. It is worth a second look when your conditions were granted years apart, because that is when a single date usually means the later grants were not given their own start.
Can I ask for a correction?
Yes — a reconsideration to your branch CRSC board. What matters is documentation: the VA decision letters showing each condition’s service-connection effective date, and your DD-214 showing creditable service. This is a records question far more than an argument.
Does this change anything if I have not filed yet?
It changes what you gather. Every VA decision letter you have ever received is potentially relevant, not just the most recent one, because the older ones establish the earlier effective dates.

Common questions
How is a CRSC effective date determined?
Condition by condition. For each condition, the effective date is the latest of three things: the first full month after your retirement date, the first full month after the VA's effective date of service connection for that condition, and the statutory floor that applies to you. Because the VA service-connects conditions at different times, one claim can carry several different effective dates.
Does the January 1, 2008 floor apply to all Chapter 61 retirees?
No. The 2008 amendment removed CRSC's 20-year service requirement. It matters for Chapter 61 medical retirees with fewer than 20 years of creditable service, who were not eligible for CRSC before January 1, 2008. A Chapter 61 retiree with 20 or more years of creditable service already qualified under the original law and falls under the June 1, 2003 floor.
What are the CRSC statutory floors?
June 1, 2003 is the program start under Public Law 107-314. Public Law 108-136 broadened eligibility for months beginning on or after January 1, 2004. Public Law 110-181 removed the 20-year service requirement effective January 1, 2008, which is when Chapter 61 retirees with fewer than 20 years and TERA retirees became eligible.
Why does the effective date matter more after Soto?
Before Soto v. United States, the Barring Act's six-year limit capped how far back CRSC could be paid, so the effective date rarely changed the outcome beyond six years. With that cap gone and DoD's interim limits rescinded on May 14, 2026, the effective date now sets the full length of the retroactive period. It is often the single largest number in a CRSC case.
