Illinois Medicare Savings Income Disregard: The $25 Rule That Changes Eligibility

The $25 Disregard Most Applicants Don't Know About

If your parent's Social Security check is a few dollars above the published income limit for Illinois's Medicare Savings Programs, don't stop there. Illinois automatically subtracts $25 from total gross unearned income per household before comparing it to the Federal Poverty Level thresholds. This standard income disregard is codified in the IDHS Worker Action Guide (WAG 25-03-02) and applies to every MSP category — QMB, SLMB, and QI-1.

That means the effective income limits are $25 higher than the raw FPL numbers you'll find on federal charts and most websites.

How the Disregard Works in Practice

Take a single Illinois senior with $1,350 per month in Social Security benefits. The 2026 QMB income limit is $1,330 per month for one person. Looking at the raw number, they're $20 over.

But Illinois subtracts $25 first: $1,350 minus $25 equals $1,325 in countable income. That's under the $1,330 threshold. They qualify for QMB — which pays their Part B premium, deductibles, and coinsurance, and automatically triggers Extra Help for prescription drug costs.

For married couples, the disregard applies once per household, not per person. If both spouses receive Social Security, their combined gross income gets one $25 deduction before being measured against the couple limits ($1,803 for QMB, $2,164 for SLMB, $2,435 for QI-1).

Other Income Adjustments Illinois Allows

The $25 disregard isn't the only adjustment. For earned income, Illinois follows the SSI formula: the first $65 of monthly wages is excluded, plus half of everything above that, plus any unused portion of the $25 general disregard. A senior with a part-time job might have significantly less countable income than their paycheck suggests.

Income received biweekly is converted to monthly using a factor of 2.15; weekly income uses 4.3. These Illinois conversion factors can produce slightly different monthly totals than simply multiplying by 2 or 4.

State pensions (TRS, SERS, SURS), VA benefits, and Railroad Retirement benefits are all counted as gross unearned income before the $25 disregard is applied. Private pensions and annuities follow the same treatment.

Why Online Income Charts Are Misleading

Federal websites, commercial broker sites, and even some official Illinois brochures list raw FPL thresholds without mentioning the state's $25 disregard. The IDHS brochure (Form HFS 3352) has historically published outdated income figures. The only reliable source for current operational numbers is WAG 25-03-02 in the IDHS Policy Manual, which reflects the actual rules caseworkers follow.

This disconnect causes real harm. Families look up the income limit online, see their parent is $10 or $15 over, and never apply. Meanwhile, Illinois caseworkers would have approved the application after applying the disregard.

Running the Numbers Before You Apply

Before deciding whether to apply, calculate your parent's countable income the way IDHS does: start with gross monthly income from all sources, subtract $25, and compare to the 2026 limits. If earned income is involved, apply the $65 plus 50% formula first.

The Illinois Medicare Savings Programs & Extra Help Guide includes a step-by-step income worksheet that mirrors the IDHS budgeting process, so you can run the same calculation a caseworker would before submitting the application.
