SLMB Income Limits 2026: What It Covers and How to Qualify

What SLMB Pays For

The Specified Low-Income Medicare Beneficiary program covers one thing: your parent's Medicare Part B premium. In 2026, that's $202.90 per month — $2,434.80 per year coming straight off a fixed-income Social Security check.

SLMB doesn't cover deductibles, coinsurance, or copayments the way QMB does. But it triggers automatic enrollment in Extra Help (the Part D Low-Income Subsidy), which pays Part D drug premiums, eliminates the prescription deductible, and caps copays at $5.10 for generics and $12.65 for brand-name drugs. The average annual value of Extra Help is about $5,700.

Combined, SLMB and Extra Help can save a qualifying senior over $8,000 per year.

2026 Federal SLMB Limits

SLMB eligibility requires countable monthly income between 100% and 120% of the Federal Poverty Level (plus the $20 unearned income disregard). For 2026:

• Individual: up to $1,616/month
• Married couple: up to $2,184/month
• Asset limit (individual): $9,950
• Asset limit (couple): $14,910

The lower bound is the QMB ceiling — if your parent's income falls below $1,350/month (single), they should apply for QMB instead, which covers substantially more. SLMB exists for the gap between QMB and QI.

Assets excluded from counting: the primary home, one vehicle, household goods, personal effects, and up to $1,500 in burial funds.

How SLMB Differs from QMB and QI

QI has a higher income ceiling but limited annual federal funding — applications are first-come, first-served. SLMB has no such cap.

States Without an Asset Test

Eleven states and the District of Columbia (12 jurisdictions) have eliminated the asset test entirely for SLMB: Alabama, Arizona, Connecticut, Delaware, District of Columbia, Louisiana, Maine, Mississippi, New Mexico, New York, Oregon, and Vermont. In these jurisdictions, only countable income determines eligibility.

Several states also set higher income ceilings than the federal baseline. If your parent's income is slightly over the federal limit, check your state Medicaid agency's specific SLMB rules before assuming they're ineligible.

How to Apply

SLMB applications go to your parent's state Medicaid agency — not Medicare or Social Security. The process:

1. Compile documents: Medicare card, Social Security card, bank statements (three months), benefit verification letters, proof of address
2. Submit the application: Online through your state's Medicaid portal or in person at the county social services office
3. Keep paying premiums: The state's buy-in takes two to three months to activate. If your parent stops paying before the buy-in is confirmed, their Medicare coverage terminates
4. Collect the retroactive refund: Once the buy-in is active, SSA reimburses premiums paid during the processing gap. SLMB coverage can be retroactive for up to three months before the application month if the applicant met eligibility during those months

The Social Security Fairness Act Factor

If your parent receives a government pension and saw their Social Security benefit increase after the WEP/GPO repeal (Social Security Fairness Act, signed January 2025), that increase counts toward the monthly income calculation. The average increase was about $360/month — enough to push a parent from QMB eligibility into the SLMB range, or from SLMB past the QI ceiling.

Run the numbers with the new benefit amount before the next annual redetermination. A parent who previously qualified for QMB at $1,300/month but now receives $1,660/month falls squarely in the QI tier — they keep the Part B premium covered and Extra Help enrollment, but lose QMB's deductible and coinsurance coverage.

The Medicare Savings Programs toolkit includes an eligibility screening worksheet, a document organizer, and an application tracker that walks through each step of the process.
