Tax Deductions for Ketamine Therapy: What You Can Claim

Can You Deduct Ketamine Therapy on Your Taxes?

Yes, in most cases. Ketamine therapy prescribed by a licensed medical provider for a diagnosed medical condition qualifies as a deductible medical expense under IRS rules. This includes the cost of the medication itself, provider consultation fees, monitoring fees, and related medical expenses.

However, the tax benefit is not automatic. You need to understand the rules, meet the thresholds, keep proper documentation, and choose to itemize your deductions. This guide explains how to maximize your tax benefit from ketamine therapy expenses.

IRS Rules for Medical Expense Deductions

The Basics

Under IRS Publication 502, you can deduct unreimbursed medical and dental expenses that exceed 7.5% of your adjusted gross income (AGI). This means:

• If your AGI is $60,000, the first $4,500 of medical expenses is not deductible
• Only expenses above that $4,500 threshold can be claimed
• You must itemize deductions on Schedule A of Form 1040 (you cannot take the standard deduction and also claim medical expenses)

What Qualifies as a Medical Expense

The IRS defines deductible medical expenses as costs for the "diagnosis, cure, mitigation, treatment, or prevention of disease." Ketamine therapy for depression, anxiety, PTSD, chronic pain, or other diagnosed conditions clearly falls within this definition when prescribed by a licensed provider.

Deductible ketamine-related expenses include:

• Provider consultation fees — Initial evaluations, follow-up visits, and monitoring sessions
• Medication costs — Prescribed ketamine in any formulation (sublingual troches, nasal spray, oral tablets)
• Lab work and testing — Blood tests, liver function panels, or other tests ordered by your provider
• Pharmacy or compounding fees — Including shipping costs for medication delivery
• Telehealth platform fees — If the platform charges a separate fee beyond the provider visit
• Blood pressure monitoring equipment — If purchased for treatment monitoring
• Integration therapy — Psychotherapy sessions that are part of your ketamine treatment program
• Travel costs — If you must travel to a physical clinic for any part of your treatment (mileage at the IRS medical rate, parking, tolls)

Not deductible:

• General wellness supplements not prescribed by your provider
• Over-the-counter items not directly related to treatment
• Costs reimbursed by insurance, FSA, HSA, or HRA
• Cosmetic or non-medical uses of ketamine

How the Deduction Works in Practice

Example Calculation

Consider a patient with an AGI of $75,000 who spends $8,400 on ketamine therapy in a tax year:

• 7.5% of $75,000 AGI = $5,625 threshold
• $9,700 - $5,625 = $4,075 deductible amount
• At a 22% marginal tax rate, this saves approximately $896 in federal taxes

Combining with Other Medical Expenses

The 7.5% AGI threshold applies to your total medical expenses, not just ketamine therapy. If you have other significant medical costs — dental work, vision care, other prescriptions, therapy, specialist visits — these all count toward exceeding the threshold.

This is where strategic planning can help. If you have a year with high medical expenses (such as starting ketamine therapy), consider scheduling other elective medical procedures or purchases in the same tax year to maximize your deduction.

Documentation Requirements

The IRS can request documentation for any deduction you claim. For ketamine therapy expenses, maintain:

Essential Records

• Invoices and receipts from your telehealth provider showing dates of service, descriptions, and amounts paid
• Pharmacy receipts for all medication purchases
• Prescription records — A copy of your prescription from a licensed provider
• Diagnosis documentation — A letter from your provider confirming your diagnosis (e.g., major depressive disorder, treatment-resistant depression, PTSD)
• Explanation of Benefits (EOBs) — If any portion was submitted to insurance, keep the EOB showing what was and was not covered
• Bank or credit card statements — Showing payment dates and amounts
• Mileage log — If claiming travel to any in-person appointments

How Long to Keep Records

The IRS generally recommends keeping tax records for at least 3 years from the date you filed the return or 2 years from the date you paid the tax, whichever is later. For medical expense deductions, keeping records for 6 to 7 years provides additional protection.

Interaction with FSAs, HSAs, and Insurance

The No-Double-Dipping Rule

You cannot deduct expenses that have been reimbursed by insurance, paid from a pre-tax FSA, or paid from an HSA. Only unreimbursed, out-of-pocket expenses qualify for the medical expense deduction.

Common scenarios:

• If insurance covers your provider visit but not the medication, you can deduct only the medication cost
• If you use FSA funds for medication, that portion is not deductible (but it was already tax-free)
• If you pay entirely out of pocket, the full amount is potentially deductible

Strategic Decision: FSA/HSA vs. Itemized Deduction

For some taxpayers, using pre-tax FSA or HSA dollars provides a greater tax benefit than the itemized medical expense deduction, especially if your total medical expenses do not significantly exceed the 7.5% AGI threshold. Consider:

• FSA/HSA advantage: Every dollar is tax-free from the first dollar spent — no threshold to meet
• Itemized deduction advantage: No annual contribution limit (unlike FSA/HSA caps), and useful if you have very high medical expenses in a given year

A tax professional can help you determine the optimal strategy. For more on tax-advantaged accounts, see our FSA/HSA guide.

State Tax Deductions

Many states also allow medical expense deductions on state income tax returns, though the rules vary:

• Some states follow the federal 7.5% AGI threshold
• Others set their own threshold (some higher, some lower)
• A few states have no income tax at all
• Some states allow a deduction even if you take the standard deduction on your federal return

Check your state's tax code or consult a tax professional for state-specific guidance.

Self-Employed Considerations

If you are self-employed and purchase health insurance through the individual market, you may be able to deduct ketamine-related expenses through the self-employed health insurance deduction (an above-the-line deduction) rather than as an itemized medical expense. This can be more advantageous because:

• It reduces your AGI directly
• You do not need to meet the 7.5% threshold
• You do not need to itemize

However, this applies only to health insurance premiums, not directly to out-of-pocket medical costs. Consult a tax professional about the best approach for your situation.

Common Mistakes to Avoid

1. Forgetting to include all expenses — Telehealth fees, shipping costs, and monitoring equipment are easy to overlook
2. Claiming reimbursed expenses — Double-check that you are not deducting amounts covered by insurance or paid from pre-tax accounts
3. Not meeting the AGI threshold — Calculate your 7.5% threshold before deciding to itemize
4. Poor documentation — Keep receipts organized throughout the year rather than scrambling at tax time
5. Missing the standard deduction comparison — For 2026, the standard deduction is $15,700 (single) and $31,400 (married filing jointly). Your total itemized deductions must exceed the standard deduction for itemizing to be worthwhile.
6. Not consulting a professional — Tax law is complex, and a CPA or tax advisor familiar with medical expenses can often find savings you would miss on your own

Working with a Tax Professional

When meeting with a tax professional, bring:

• A summary of all ketamine therapy expenses for the tax year
• Documentation of your diagnosis and prescription
• Records of any insurance reimbursements or FSA/HSA payments
• Your total medical expenses from all sources
• Your estimated AGI

If your tax preparer is unfamiliar with ketamine therapy, explain that it is a prescribed treatment for a diagnosed medical condition and point them to IRS Publication 502 for the applicable rules.

The Bottom Line

Ketamine therapy is a legitimate medical expense that can provide meaningful tax savings for patients who itemize deductions and exceed the 7.5% AGI threshold. The key is meticulous documentation, strategic timing of expenses, and understanding how the deduction interacts with other tax-advantaged options like FSAs and HSAs.
