AHCCCS Income Calculation: Does Social Security Count and How Disregards Work

Your parent's Social Security check is $1,380 a month, and the QMB income limit is $1,350. Does that mean they're $30 over and out of luck? Not necessarily. AHCCCS applies income disregards that change the math — and the way Social Security income gets counted isn't as straightforward as comparing the check amount to the published limit.

Yes, Social Security Counts — But as Gross, Not Net

AHCCCS uses gross Social Security benefits for MSP eligibility. That means the total Title II amount before any deductions — before Medicare Part B premiums are withheld, before tax withholdings, before any voluntary garnishments.

This confuses many applicants. The amount deposited into your bank account is lower than the gross benefit because SSA already subtracted $202.90 for Part B. But AHCCCS looks at the higher gross figure, not the deposit amount.

Where to find your gross benefit: the SSA Award Letter (also called the COLA letter, mailed each December) shows the gross monthly benefit amount for the coming year. This is the number AHCCCS uses.

The $20 Unearned Income Disregard

Here's where the published income limits get misleading. AHCCCS applies a universal $20 per month disregard on unearned income. Social Security is unearned income, so the first $20 of monthly benefits is excluded from the eligibility calculation.

When AHCCCS publishes its official limits in the Eligibility Policy Manual, those figures are the net FPL thresholds ($1,330 for QMB single in 2026). But because of the $20 exclusion, the actual gross income you can have and still qualify is $20 higher:

For couples, the same $20 disregard applies to the household (not $20 per person): QMB couple limit is $1,824, SLMB couple is $2,184, QI couple is $2,455.

So if gross Social Security is $1,345, the countable income after the disregard is $1,325 — well under the QMB net threshold.

What About Earned Income?

Some Medicare beneficiaries still work part-time. AHCCCS applies SSI-standard earned income exclusions:

• The first $65 of monthly earned income is fully excluded.
• Half of the remaining gross earnings is excluded.
• The $20 unearned income disregard can shift to earned income if not used against unearned income.

Example: A senior has $1,200 in Social Security and $400 in part-time earnings. After disregards: Social Security becomes $1,180 (minus $20), earned income becomes $167.50 (minus $65, then half of $335). Total countable: $1,347.50 — under the QMB limit.

Income Types That Don't Count

Several common income sources are excluded entirely from AHCCCS MSP calculations:

• VA Aid and Attendance and housebound benefits.
• Reimbursement for medical expenses from any source.
• In-kind support and maintenance — when an adult child pays a utility company or landlord directly on behalf of the parent, that vendor payment is excluded under AHCCCS policy.

However, direct cash payments from an adult child to the parent are counted as unearned income. The distinction matters: pay the electric company directly rather than giving your parent cash to pay it.

Pensions and commercial annuities count in full. VA compensation (other than the specific exclusions above) counts. Rental income from property counts.

Running the Numbers Before You Apply

Don't let a quick comparison between your parent's Social Security deposit and the published QMB limit scare you off. Start with the gross benefit from the SSA Award Letter, apply the $20 disregard, and apply any earned income exclusions. The actual countable income is often hundreds of dollars below what people assume.

The Arizona Medicare Savings Programs & Extra Help Guide includes an income calculation worksheet that walks through every disregard step-by-step, including how to handle pensions, part-time earnings, and adult-child support — so you can determine which MSP tier (QMB, SLMB, or QI) your parent qualifies for before filing.
