Special Monthly Compensation (SMC) is the extra layer of VA disability compensation for Veterans with specific anatomical losses, loss of use, or who require aid and attendance. Some SMC (the K-rate) is added to your base rating. Other SMC (the L-through-T schedule) is a higher fixed rate that replaces your base 100% amount. Either way, Veterans entitled to SMC are owed more than the base rate table alone shows.
Most Veterans entitled to SMC don't know about all the tiers. The K-rate gets added incidentally to many claims. The L through T schedule is rarely walked through systematically by raters. The half-steps (L½, M½, N½) are almost never volunteered. And Bradley v. Peake's SMC-S pathway via TDIU is one of the most underclaimed VA benefits.
This guide is the structure of SMC, what triggers each tier, and the math at current 2026 rates (effective December 1, 2025).
A note before we start: this guide is information only. We don't file claims or advise you on what to claim. Claims are filed through the VA, and a VA-accredited Veterans Service Officer (VSO) can prepare and submit a claim for you at no cost. You can find one through the VA Office of General Counsel accreditation search.
The K-rate, the building block
SMC-K is the base-level SMC. It's a flat dollar amount added to your monthly compensation for each qualifying anatomical loss or loss of use. As of 2026, the K-rate is $139.87 per qualifying loss.
K-rate triggers:
- Loss or loss of use of one foot
- Loss or loss of use of one hand
- Loss of one or both feet
- Loss of one or both hands
- Loss of vision in one eye (5/200 or worse) when the other eye is also impaired
- Loss of one ear's hearing (deafness)
- Loss of speech (functional muteness)
- Loss of breast(s) due to mastectomy
- Loss of creative organ (testicles, ovaries, uterus, etc.)
- Permanent and total loss of use of an arm or leg
You can stack K-rates. Multiple losses = multiple K payments. A vet with loss of both feet plus loss of one hand stacks 3 K-rates ≈ $419.61/month on top of base compensation.
K-rates have no upper limit on how many you stack in number, but in practice once your combined losses qualify you for a higher SMC tier (L through T), you receive that higher tier rate instead.
The L through T schedule, major anatomical losses
This is the rate-by-tier schedule for catastrophic losses. These are fixed monthly rates that replace your base 100% rate (they're higher because they account for severe loss and care needs), not amounts added to it. The figures below are 2026 rates for a Veteran with no dependents, rates are higher with a spouse, children, or dependent parents.
SMC-L, Aid and Attendance (A&A), or loss of both hands, both feet, a hand and a foot, or both eyes (5/200 or worse); or permanently bedridden
- 2026 rate: $4,900.83/mo
SMC-L½, L-level need plus an additional rateable disability at 50%+
- $5,154.00/mo
SMC-M, loss of both hands; or both legs near the hip; or one arm and one leg with loss of use; or blindness with light perception only
- $5,408.55/mo
SMC-M½, M-level plus an additional rateable disability at 50%+
- $5,780.00/mo
SMC-N, loss of both arms near the shoulder; or both legs at a level preventing prosthesis; or blindness with no light perception plus deafness
- $6,152.64/mo
SMC-N½, N-level plus an additional rateable disability at 50%+
- $6,514.00/mo
SMC-O / SMC-P, multiple independent SMC-tier losses (e.g., paraplegia plus blindness, or deaf-blindness)
- SMC-O: $6,877.12/mo. SMC-P is an intermediate rate that can fall between SMC-O and SMC-R.1 depending on the exact combination of losses.
SMC-R.1, entitlement at the O/P level plus the regular aid-and-attendance allowance (permanent need for personal healthcare services)
- $9,826.88/mo
SMC-R.2, R.1 level but needing a higher level of aid and attendance (skilled-care equivalent)
- $11,271.67/mo
SMC-T, severe traumatic brain injury requiring R.2-level aid and attendance who, but for that care, would need hospitalization or institutional care
- $11,271.67/mo (paid at the R.2 amount)
SMC-S (Statutory Housebound), 100% schedular OR TDIU rating PLUS an additional 60% disability rating, AND substantially confined to home
- 2026 rate: $4,408.53/mo total for a Veteran with no dependents, about $470/month more than the 100% base rate of $3,938.58.
The half-step bumps (L½, M½, N½)
The half-step tiers (38 CFR §3.350(f)) exist for vets who meet the requirements of a tier AND have an additional independent disability rated 50% or more. They get bumped up one half-step.
Example: a vet entitled to SMC-M AND a separate 50%+ rated condition gets bumped to SMC-M½, that's $5,780.00 vs $5,408.55, about $371/month more.
These half-step tiers are rarely walked through systematically. A Veteran with multiple service-connected conditions who qualifies for a base SMC tier and has an additional independent 50%+ disability may be entitled to the half-step rate.
Aid and Attendance, the most-claimed SMC pathway
A&A under SMC-L is for Veterans who need help from another person with regular activities of daily living: bathing, dressing, eating, toileting, medication management. (A separate Aid & Attendance enhancement exists for the needs-based VA Pension and for surviving spouses, different program, similar care criteria. See our Aid & Attendance guide.)
Two A&A standards under SMC:
- L-rate A&A, regular need for personal healthcare services
- R.1 / R.2, need at a skilled-care equivalent level
A&A entitlement turns on a medical assessment of which activities of daily living a Veteran needs help with and how often. The VA makes that determination through its claim process.
Common conditions associated with A&A need: dementia, Parkinson's, severe arthritis, end-stage cardiovascular disease, terminal cancer, severe PTSD with self-care deficits.
A Veteran (no dependents) entitled to SMC-L receives $4,900.83/month in 2026. Note the SMC-L rate replaces the 100% base rate, it does not stack on top of it. It's higher than the $3,938.58 base precisely because it accounts for the aid-and-attendance need.
Housebound, the lesser-claimed parallel
Housebound (SMC-S) is for vets who are "substantially confined to the home and immediate premises" due to their service-connected disabilities. The standard is lower than A&A, you don't need help with daily activities, you just have to be substantially unable to leave the home.
Two pathways:
- 100% schedular + a separate 60% disability + housebound facts, pays the SMC-S rate ($4,408.53/mo, ~$470 more than base 100%)
- Bradley v. Peake, TDIU based on a single condition (treated as 100%) + a separate 60%+ disability = SMC-S without needing to prove housebound facts
That second pathway is the underutilized one.
Bradley v. Peake, SMC-S via TDIU
Bradley v. Peake (22 Vet. App. 280, 2008) held that if a single service-connected condition supports a TDIU rating (treated as 100%), and you ALSO have a separate service-connected disability rated 60% or higher, you qualify for SMC-S, without needing to prove housebound status.
That makes TDIU a slightly better deal than schedular 100% in this narrow case. A vet with TDIU (from one condition) + a separate 60% rating gets SMC-S (~$470/mo extra) that a vet with 100% schedular + 60% would only get with housebound facts.
This Bradley pathway is one of the least-known parts of SMC. A Veteran rated TDIU based on one condition who also has a separate service-connected condition at 60%+ may be entitled to SMC-S under it.
The Bilateral Factor (38 CFR §4.26)
Separate from SMC but often relevant: the bilateral factor under §4.26 adds a bonus when you have disabilities affecting paired extremities (both arms, both legs, paired skeletal muscles). The math:
- Combine the bilateral disabilities under §4.25
- Add 10% of that combined value (before any rounding)
- Then combine that result with your other ratings, and round only at the end
Example: a vet has a 30% right knee and a 20% left knee.
- Combine 30 and 20: 100 × (1 − 0.30) × (1 − 0.20) = 56% efficient → 44% disability
- Bilateral factor: 44 + (44 × 0.10) = 48.4%
- That 48.4% then combines with any other ratings under §4.25
The bilateral factor is applied automatically by the VA when paired-extremity disabilities are rated, it isn't something a Veteran requests separately.
Combat-Related Special Compensation (CRSC) and CRDP
CRSC and CRDP are separate from SMC but often confused. They apply to military retirees who are also rated for VA disability (full breakdown in our CRDP vs CRSC guide):
- CRDP (Concurrent Retirement and Disability Pay), restores military retired pay that was previously offset dollar-for-dollar by VA disability. Available to retirees with a VA rating of 50%+. Automatic, taxable.
- CRSC (Combat-Related Special Compensation), a separate, tax-free payment for combat-related disabilities; requires an application. You receive CRDP or CRSC, whichever pays more, not both.
The Major Richard Star Act (still moving through Congress as of 2026, not yet law) would extend concurrent receipt to combat-injured Veterans medically retired with fewer than 20 years of service, a long-standing gap.
These interact with SMC cleanly: SMC is paid on top of your VA disability comp and is not offset by military retired pay.
Worked example, putting it together
Hypothetical: 50-year-old vet, post-9/11 era, separated 2010, no dependents.
Conditions:
- PTSD rated 70%
- TBI rated 50%
- Loss of use of right hand (combat injury), qualifies for an SMC-K rate
- Bilateral knee impairment (right 30%, left 20%)
Base rating math:
- Knees combined: 100 × (1 − 0.30) × (1 − 0.20) = 56% efficient → 44%; bilateral factor 44 + 4.4 = 48.4%
- Order highest to lowest (70, 50, 48.4) and combine: 100 → 70 = 30 eff; 30 → 50 = 15 eff; 15 → 48.4 = 7.74 eff; combined = 100 − 7.74 = 92.26% → rounds to 90%
Final schedular rating: 90%.
But this vet is unemployable because of PTSD + TBI. Files TDIU successfully, paid at the 100% rate.
SMC analysis:
- Loss of use of right hand triggers an SMC-K rate: +$139.87/mo
- TDIU (treated as 100%) + a separate disability at 60%+ (PTSD at 70% qualifies) = SMC-S under Bradley
Total monthly compensation (no dependents, 2026):
- SMC-S rate (which already includes the 100% equivalent + housebound): $4,408.53
- Plus SMC-K: $139.87
- Total: $4,548.40/month
Without the SMC-K and the Bradley/SMC-S claim, this vet would sit at the plain 100% rate of $3,938.58. The SMC layers add about $610/month, roughly $7,320/year.
What this guide is not
This guide is informational. It explains the structure of SMC, what triggers each tier, and the dollar amounts at current rates. It does not file claims, complete VA forms, or advise you on what to claim or how to claim it.
Claims are filed through the VA. A VA-accredited Veterans Service Officer (VSO) can prepare and submit a claim for you at no cost, that is specifically what VSOs do. Find one through the VA Office of General Counsel accreditation search.
SMC is one of the highest-leverage things to know about VA disability comp. The SMC layers can add thousands of dollars per year on top of a base rating. The only binding numbers are on your VA rating decision. To see the dollar value of a given rating and SMC tier, use our disability calculator, and compare against the official SMC schedule at va.gov.
