The 30-second version
CRDP is automatic and taxable. CRSC is application-only and tax-free. By federal law you can't collect both in the same month — DFAS pays whichever is higher in gross dollars. But "higher" before taxes is not the same as "higher" after taxes, and CRSC's tax-free status means it often nets you more even when CRDP looks larger on paper. Add in the fact that CRSC backpay can reach back years and is also tax-free, and the case for filing CRSC — even if you're already on CRDP — is a lot stronger than most retirees realize.
What each one is, side by side
Why CRSC matters even if you already get CRDP
Once you're approved for CRSC, DFAS sends you an annual election letter. You pick which one to receive that year. DFAS will tell you which pays more in gross dollars — and on that surface comparison, CRDP often appears equal or higher because it covers your full combined rating.
What the letter doesn't put in bold:
1. CRDP is taxed. CRSC isn't.
Same gross dollar amount nets you different take-home depending on which pipe it comes through. For a retiree in the 22% federal bracket, every $1,000 of CRDP nets roughly $780 after federal tax. The same $1,000 of CRSC nets the full $1,000. That's a 28% difference in pocketed dollars on the same gross figure. State income tax (if your state taxes military retirement) widens the gap further.
2. The math may favor CRSC outright.
CRSC isn't capped the same way CRDP is. CRDP restores VA Waiver dollars up to the value of your full combined rating. CRSC restores combat-related dollars up to the longevity portion of your retirement. For retirees whose worst conditions are combat-related — TBI from a blast, hearing loss from weapons exposure, joint and back conditions from rucks and jumps, breathing issues from burn-pit exposure — those conditions carry the heaviest dollar weight in the rating, and they all count toward CRSC. The CRSC monthly amount can actually exceed the CRDP amount before you even apply the tax difference.
3. CRSC backpay is real money you can't get any other way.
This is the one most retirees miss entirely. CRSC backpay reaches back to the date of eligibility — often six, ten, or fifteen years of withheld VA Waiver dollars — and it's paid as a tax-free lump sum. CRDP doesn't pay back like that. It was phased in starting in 2004 and there is no current retroactive recovery. So even before you decide which check to take going forward, the one-time CRSC backpay is often the single largest financial reason to file.
A simplified worked example
Career Army NCO, 22 years, 70% combined VA rating
Of the 70%, 50% is from combat-related conditions (back, knees, hearing, TBI). The other 20% is for non-combat sleep apnea and hypertension.
Approximate monthly figures (illustrative, not a quote):
Net after 22% federal tax: ≈ $1,338
Net: $1,200
On gross dollars, CRDP wins by $516/month. On after-tax dollars, CRDP wins by only $138 — a much narrower margin. But this retiree files for CRSC anyway, because:
- CRSC backpay reaches back to his retirement effective date — twelve years of recoverable VA Waiver dollars on combat-related conditions, paid tax-free as a lump sum (often $30,000–$80,000+).
- If he later adds a combat-related condition or his rating changes, CRSC's monthly figure may surpass CRDP, and the election can be switched annually.
Numbers above are illustrative for explanation only. Standfast does not guarantee approval, rating percentage, or backpay amount; figures depend on individual circumstances and the determinations of your service branch's CRSC board.
"So why isn't CRSC automatic like CRDP?"
Because CRDP is a math calculation DFAS can run on its own — your years of service and your VA combined rating are already in the system. CRSC requires a determination that each condition is combat-related, and that determination has to be made by a human board reviewing evidence you provide. Congress wrote it that way deliberately: the tax-free status of CRSC is what makes it valuable, and the application process is what keeps that benefit narrowly targeted to combat-related causation rather than every disabling condition a service member accumulates.
The result: most first-time CRSC packets get denied. Not because the retiree doesn't qualify — but because the paperwork didn't tell the causation story the way the board needs to read it. That's the work Standfast does.
The bottom line
If you're a retiree already receiving CRDP and you have any condition tied to combat, hazardous duty, training that simulated war, or instrumentality of war, filing for CRSC is almost always worth it. The tax difference, the potential for CRSC to outpay CRDP outright, and the tax-free backpay together make CRSC one of the most under-claimed benefits in the entire military retirement system.
