HSA and Aging Parents: When You Can Pay Their Medical Bills

The Rule Most People Miss

Your HSA can pay for an aging parent's medical expenses. Even if your parent does not live with you. Even if they are on Medicare. Even if they file their own tax return.

The catch is one specific IRS test. If your parent passes it, every dollar you spend on their care comes out of your HSA tax-free.

That is a 22% to 37% discount on prescriptions, doctor visits, hearing aids, and in-home care. For a family spending $8,000/year on a parent's medications, the tax savings hit $1,760/year at the 22% bracket.

Most people never check the test. They pay out of pocket with after-tax dollars. That is the mistake.

The Test: IRC Section 152 Qualifying Relative

The IRS uses one definition for HSA dependents. It comes from IRC Section 152(d), the "qualifying relative" rule. IRS Publication 502 confirms this is the test that controls medical expense eligibility. Publication 969 confirms it controls HSA distributions.

A parent qualifies if they meet four conditions:

• ●Relationship. They are your parent, step-parent, or in-law. This one is automatic.
• ●Gross income. Their 2026 gross income is under $5,300. The non-taxable portion of Social Security is excluded from gross income for this test (IRC §152(d)(1)(B)). Any portion that is taxable under IRC §86 does count. For most retirees on Social Security alone, none of it is taxable. But if the parent has other income, up to 85% of their Social Security may become taxable and counted toward the gross income test. Pensions and IRA withdrawals do count.
• ●Support. You provide more than half of their financial support for the year.
• ●Not a qualifying child of someone else. Almost never an issue with parents.

Notice what is missing. There is no residency test for parents. Qualifying relatives under IRC Section 152(d) have no residency requirement at all. Only qualifying children under 152(c) have a "more than half the year" residency test. Parents are listed at 152(d)(2)(C), which means they qualify regardless of where they live. Your mother can live in Florida while you live in Ohio. She can live in assisted living. She can live in her own house. None of it matters for HSA purposes.

The Gross Income Trap

This is where most people get tripped up. Gross income for the qualifying relative test is not the same as your parent's full retirement income.

The non-taxable portion of Social Security is excluded from gross income for this test (IRC §152(d)(1)(B)). Any portion that is taxable under IRC §86 does count. For most retirees on Social Security alone, none of it is taxable. But if the parent has other income, up to 85% of their Social Security may become taxable and counted toward the gross income test. A parent collecting $24,000/year in Social Security with no other income has $0 in gross income for this test. They pass easily.

What counts as gross income:

• ●Pension payments
• ●Traditional IRA and 401(k) distributions
• ●Annuity income (taxable portion)
• ●Interest and dividends from non-tax-exempt accounts
• ●Rental income
• ●Wages from part-time work

A parent with a $40,000/year pension fails the test instantly. $40,000 is way over $5,300. They cannot be your HSA dependent regardless of how much support you provide.

A parent with $30,000/year in Social Security and $4,800 in dividends usually passes. The $4,800 is under $5,300. Watch the IRC §86 trap: at higher income levels, up to 85% of Social Security can become taxable and would count toward the test. Run the numbers with a tax professional in close cases.

Source: Rev. Proc. 2025-32 sets the 2026 gross income threshold at $5,300, as reflected in IRS Publication 501.

The Support Test

You must provide more than 50% of your parent's total support for the year.

Total support includes housing, food, medical care, transportation, clothing, and recreation. Add up everything spent on your parent's care from all sources. Your share has to top half.

A parent in assisted living costing $60,000/year is a common case. If you pay $36,000 of that and Medicare plus their savings cover $24,000, you are at 60%. You pass.

If you pay $25,000 and Medicare plus their savings cover $35,000, you are at 42%. You fail.

Multiple support agreements exist for siblings splitting costs. IRS Publication 501 covers this (not Pub 502). Rule: each sibling must individually pay more than 10% of support, and the group together must pay more than 50%. If you and your two siblings each pay 33%, you all qualify (each over 10%, group at 100%). Sign a multiple support agreement designating one sibling as the dependent claimer for that year.

Three Real Scenarios

Scenario 1: Mom on Medicare and Social Security only

Your mother is 78. She collects $24,000/year in Social Security. No pension. No part-time work. $1,200/year in CD interest.

Gross income for the test: $1,200. Under $5,300. Passes.

You pay her $14,000/year in out-of-pocket medical costs not covered by Medicare. She lives in her own apartment, and her total annual support is $35,000. You cover $20,000. That is 57%. Passes.

She is your HSA-qualifying dependent. You can run her medical expenses through your HSA.

Scenario 2: Dad with a pension

Your father is 72. He gets $20,000/year in Social Security and $40,000/year from a corporate pension.

Gross income for the test: $40,000. Way over $5,300. Fails.

It does not matter if you pay 100% of his medical bills. He is not your HSA-qualifying dependent. You pay his medical expenses with after-tax dollars.

Scenario 3: Mom in assisted living

Your mother is 84. $28,000/year in Social Security. $0 other income. Lives in assisted living that costs $72,000/year. You pay $45,000. Medicare and her savings cover the rest.

Gross income: $0. Passes.

Your share of support: 62%. Passes.

She is your HSA-qualifying dependent. Her assisted living costs are partially HSA-eligible if the care is medically necessary. IRS Publication 502 has the breakdown for nursing care versus custodial care.

The Decision Tree

Run your parent through this in order:

• ●Is this person your parent, step-parent, or parent-in-law? If yes, continue. If no, different rules apply.
• ●Is their 2026 gross income (excluding Social Security) under $5,300? If yes, continue. If no, they fail. Stop.
• ●Did you provide more than half their total support for the year? If yes, continue. If no, check the multiple support agreement option.
• ●They qualify. Save their receipts in your HSA records. Pay any HSA-eligible medical expense for them tax-free.

That is the whole test. Four steps.

What You Can Pay For Once They Qualify

If your parent passes the test, your HSA can cover any medical expense the IRS recognizes for them. The list is long.

• ●Doctor visits, specialist consultations, surgery
• ●Prescription medications
• ●Hearing aids and batteries
• ●Eyeglasses, contact lenses, eye exams
• ●Dental work, dentures, orthodontics
• ●Mobility devices: walkers, wheelchairs, scooters
• ●In-home nursing care (if medically necessary)
• ●Assisted living costs (the medical care portion)
• ●Nursing home costs (if primarily for medical care)
• ●Physical therapy, occupational therapy
• ●Medicare Part B and Part D premiums for the parent
• ●Long-term care insurance premiums (up to age-based caps)
• ●Mental health expenses are eligible, including therapy and prescriptions

For 2026, long-term care insurance premium caps from Rev. Proc. 2025-32 are:

A 78-year-old parent paying $5,800/year in long-term care insurance premiums is fully covered. A 78-year-old paying $7,500/year hits the $6,200 cap.

The ACA Confusion

Here is where families get the rules tangled. ACA insurance dependent rules and IRS Section 152 dependent rules are different systems.

A parent on Medicare is not on your insurance plan. Medicare is their insurance. None of that matters for HSA purposes. The HSA rule cares about the qualifying relative test, not whose health plan they are enrolled in.

You can have a parent who:

• ●Is on Medicare
• ●Files their own tax return
• ●Lives 1,000 miles away
• ●Is not on your health insurance

And still be your HSA-qualifying dependent if they pass the income and support tests.

The HSA does not care about insurance enrollment. It cares about IRC Section 152.

The Receipt Strategy

If your parent qualifies this year, save every medical receipt you pay for them. Track them the same way you track your own.

You do not have to reimburse yourself immediately. HSA reimbursements have no time limit. An expense paid in 2026 can be reimbursed in 2046. As long as it was qualified and you have the receipt. This is the delayed reimbursement strategy.

For aging parents, this matters because the income test resets every year. Your mother passes the test in 2026 but inherits a pension in 2028 and fails after that. The 2026 expenses you saved are still eligible. Reimburse from your HSA whenever you want.

Tripl tracks expenses for any family member you choose. Tag them, save the receipt, and the system holds them until you reimburse. No time limit.

Form 8889 Reporting

When you withdraw from your HSA to pay for a parent's medical expense, you report it on Form 8889 reporting. Line 15 captures qualified medical expenses paid from the HSA.

Your parent's qualified medical expenses count on Line 15 the same as your own. No separate line. No special schedule. The IRS treats your dependent's medical expenses identically to yours for HSA purposes.

If audited, you need:

• ●Receipts for the medical expenses
• ●Documentation that your parent passed the qualifying relative test that year (income summary, support calculation)
• ●Confirmation that you paid the expense

That is it. Most HSA audits are paperwork checks, not deep-dive investigations. Keeping a clean record is enough.

What This Means for Your HSA Strategy

A parent who qualifies as your dependent expands your HSA spending universe by their entire annual medical bill.

Out-of-pocket medical spending for someone 75 or older typically runs into the thousands of dollars annually, per Kaiser Family Foundation analyses (varies by year and methodology). Call it $5,000 as a rough working number. That is $5,000 you can route through pre-tax dollars instead of post-tax.

At a 22% federal bracket plus state, the tax savings are roughly $1,200/year per qualifying parent at that spending level.

Over 10 years, that is around $12,000 in tax savings on medical expenses you were going to pay anyway.

You are not spending more. You are paying the same medical bills with better money.

The same framing that makes the HSA powerful for your own retirement applies here. See what happens to your HSA after 65 for how this stacks with everything else. Also worth a read: the common HSA mistakes that cost thousands, several of which apply directly to dependent-care planning.

The Reframe

Most people treat the HSA as a personal account. It is a household account.

The IRS gives you tax-free spending power for yourself, your spouse, and any dependent who passes Section 152. Aging parents qualify more often than people realize. The non-taxable portion of Social Security being excluded from gross income is the door most people walk past.

Check the test. If your parent passes, every medical receipt of theirs is your tax-free expense. If they fail, you pay full freight. The math is binary.

The hard part is not running the HSA. It is knowing the test exists.

Frequently Asked Questions

Does my parent need to live with me?

No. Qualifying relatives under IRC Section 152(d) have no residency requirement at all. Parents are listed at 152(d)(2)(C) and qualify regardless of where they live.

Does Social Security count toward the $5,300 income test?

The non-taxable portion of Social Security is excluded from gross income for this test (IRC §152(d)(1)(B)). Any portion that is taxable under IRC §86 does count. For most retirees on Social Security alone, none of it is taxable. But if the parent has other income, up to 85% of their Social Security may become taxable and counted toward the gross income test. Pensions, IRA distributions, and other taxable income do count.

Can I claim my parent as a dependent on my tax return AND use my HSA for them?

You do not have to claim them on your tax return to use HSA funds. You only need them to meet the qualifying relative test. Even if you do not claim them as a dependent, HSA eligibility still works.

What if my siblings and I split my mom's costs?

Use a multiple support agreement. IRS Form 2120. One sibling claims the dependent that year. Only that sibling can use HSA funds for her expenses that year.

Can I use my HSA for my parent's Medicare premiums?

Yes, if they pass the qualifying relative test. Medicare Part A, B, and D premiums are HSA-eligible for any qualifying dependent.

Are nursing home costs HSA-eligible for a dependent parent?

Yes, if the primary reason for the nursing home is medical care. Custodial care alone is not eligible. IRS Publication 502 has the full distinction.
