HSA Eligible Expense Verification Checklist (2026) | HSA

Confirm your HDHP meets IRS requirements (minimum deductible, maximum out-of-pocket) for 2026.

If your health plan doesn't qualify as an HDHP, you are not eligible to contribute to an HSA, and any contributions made could be subject to penalties.

Verify you do not have other disqualifying health coverage (e.g., a low-deductible plan, Medicare, TRICARE).

Having other non-HDHP coverage generally makes you ineligible for HSA contributions, even if you have an HDHP. There are limited exceptions for specific types of supplemental coverage.

Review IRS Publication 502 for the most current definition of 'medical expenses' for 2026.

The IRS guidelines are the ultimate authority. Staying updated ensures you avoid using HSA funds for non-eligible items, preventing potential taxes and penalties.

Understand that expenses reimbursed by another health plan (e.g., dental insurance) are NOT HSA eligible.

You cannot 'double dip.' If another plan paid for it, or will pay for it, you cannot use your HSA for that same expense. This prevents improper tax deductions.

Confirm the expense was incurred AFTER your HSA was established.

Expenses incurred before your HSA was opened are not eligible for tax-free reimbursement, even if they would otherwise be qualified medical expenses.

Verify prescription medications against IRS Publication 502.

Most prescription drugs are eligible, but always confirm, especially for non-traditional medications. This ensures proper tax-free withdrawals.

Confirm eligibility for doctor's office visits, specialist consultations, and hospital stays.

These are standard eligible expenses, but ensure you retain EOBs and receipts to prove the medical nature and cost.

Check dental care costs: cleanings, fillings, extractions, orthodontia, and dentures.

All generally eligible. Keeping detailed dental records is important for family tax purposes, especially with children needing braces.

Verify vision care expenses: eye exams, prescription glasses, contact lenses, and LASIK surgery.

These are fully eligible. For LASIK, ensure you have the procedure details and receipts for substantiation.

Confirm over-the-counter (OTC) medications and feminine hygiene products are eligible.

Thanks to recent legislation, many OTCs are now eligible without a prescription. This saves out-of-pocket money for common ailments.

Check for eligible medical equipment and supplies (e.g., crutches, blood sugar test kits, bandages).

These items are eligible if used for medical purposes. Avoid using HSA funds for general household items that aren't medically prescribed.

Determine if mental health services, including therapy and counseling, are eligible.

Mental health care is fully eligible, just like physical health care. Ensure your provider is licensed and services are for medical treatment.

Verify chiropractic care, acupuncture, and other alternative treatments for medical necessity.

These are eligible if for medical care (e.g., treating back pain), not general health. A doctor's note or clear medical diagnosis strengthens eligibility.

Check if weight-loss programs or smoking cessation programs are prescribed to treat a specific disease.

Eligible ONLY if prescribed by a doctor to treat a diagnosed disease (e.g., obesity, heart disease, nicotine addiction), not for general wellness.

Confirm if special education expenses for learning disabilities are medically necessary.

Eligible if recommended by a physician for a child with a learning disability to overcome the disability. Requires clear medical substantiation.

Determine eligibility for service animals and their maintenance if medically necessary.

Eligible if the animal assists with a specific medical condition (e.g., guide dog for blindness). Documentation of medical necessity is key.

Check if home modifications for medical care (e.g., wheelchair ramps) are eligible.

Eligible if primarily for medical care and do not increase the value of the home. The cost exceeding any value increase is what's eligible.

Retain all receipts, Explanation of Benefits (EOB), and doctor's notes for at least 3 years.

These documents prove the expense was incurred, the amount, and its medical necessity. The 3-year rule is standard for tax audits.

Keep a digital or physical log of all HSA withdrawals, dates, amounts, and associated expenses.

A clear log helps you track your spending, reconcile with your HSA statements, and quickly pull information if audited.

Obtain a Letter of Medical Necessity (LOMN) from a physician for any non-obvious eligible expenses.

An LOMN provides clear, expert justification for expenses like gym memberships or special diets, which are only eligible under specific medical conditions.

Cross-reference HSA statements with your personal expense log regularly.

This helps catch discrepancies early, ensures all withdrawals are accounted for, and prevents accidental overspending on non-eligible items.

Store documentation securely, whether in cloud storage, a dedicated folder, or a fireproof safe.

Lost or damaged records can be as problematic as not having them at all. Secure storage protects your ability to prove eligibility.

Ensure documentation clearly shows the date of service, description of service, and amount paid.

Vague receipts are insufficient. The IRS needs specific details to confirm the expense's eligibility and the exact amount claimed.

Review all HSA withdrawals against your expense log and retained documentation.

A final check ensures no non-eligible expenses slipped through and that all eligible expenses have corresponding proof, crucial for tax filing.

Confirm all contributions for the year are within IRS limits for 2026 (including employer contributions).

Exceeding contribution limits can result in a 6% excise tax. Ensure you haven't over-contributed, especially if you changed jobs or coverage.

Identify any eligible expenses paid out-of-pocket that you haven't yet reimbursed from your HSA.

You can reimburse yourself for past eligible expenses at any time, even years later. This is a powerful strategy to let your HSA investments grow.

Plan for next year's HSA contributions and potential investment strategies.

Proactive planning helps you maximize future tax savings and investment growth, especially for long-term retirement healthcare planning.

Consult your tax advisor regarding any unusual or large medical expenses for tax filing.

Complex situations benefit from professional advice, ensuring you claim all eligible deductions and avoid any misreporting.

Ensure Form 1099-SA and Form 5498-SA from your HSA provider are accurate.

These forms report your distributions and contributions to the IRS. Verify their accuracy against your records before filing your taxes.
