In most states that charge a sales tax, hearing aids are exempt, but the rules on sales tax on hearing aids by state are not uniform: some states zero them out at the register, some require a prescription for the exemption to apply, and a few tax them at the full combined rate. Five states have no statewide sales tax at all — Alaska, Delaware, Montana, New Hampshire, and Oregon — so the question never comes up there.1Tax Foundation. State and Local Sales Tax Rates, 2026 In the other 45, the answer depends on how your state’s tax code classifies the device.
The Three Ways States Treat Hearing Aids
Every state’s tax code sorts hearing aids into one of three buckets. The bucket is set by how the legislature defines “prosthetic device” or “durable medical equipment,” and whether hearing aids fit inside that definition.
Full Exemption
The largest group of states exempts hearing aids outright. These states classify them alongside artificial limbs and pacemakers as devices that replace or restore a lost body function. No prescription, no exemption certificate, no special paperwork at checkout. The tax line on the invoice is simply zero.
Many of these states follow the Streamlined Sales and Use Tax Agreement’s definition of a prosthetic device — a replacement, corrective, or supportive device worn on or in the body. A hearing aid fits comfortably inside it. The agreement, however, lets member states carve hearing aids out if they choose, which is why treatment still varies among states that otherwise use the same framework.2Streamlined Sales Tax Governing Board. Streamlined Sales and Use Tax Agreement
Conditional Exemption
A second group exempts hearing aids only when certain conditions are met. A valid prescription from a licensed physician or audiologist is the most common requirement. The prescription documents medical necessity; without it, the sale is taxed at the full rate.
Other conditions can attach too. Some states require the seller to be a licensed hearing aid dispenser. Some limit the exemption to specific buyers, such as hospitals or government agencies. A few tie it to the patient’s age. Keep the prescription or exemption certificate on file — states can audit the transaction later and pull the exemption if the paperwork is missing.
Full Taxation
A smaller group of states treats hearing aids like any other consumer electronic and charges the full combined state-and-local rate. Either the legislature never wrote a medical device exemption, or it wrote one narrow enough to leave hearing aids out. Combined state and local rates run above 9% in some areas.1Tax Foundation. State and Local Sales Tax Rates, 2026 On a pair of hearing aids running several thousand dollars, that’s a real number.
OTC Hearing Aids and the Prescription Trap
The FDA created a category of over-the-counter hearing aids in 2022, letting adults with perceived mild to moderate hearing loss buy devices without a prescription or professional fitting.3U.S. Food and Drug Administration. OTC Hearing Aids: What You Should Know That change has a direct tax consequence that catches people off guard.
In states with a full, unconditional exemption, OTC hearing aids generally qualify for the same zero-tax treatment. The FDA still classifies them as medical devices, and most state definitions don’t distinguish between OTC and prescription models.3U.S. Food and Drug Administration. OTC Hearing Aids: What You Should Know
The trap sits in states with conditional exemptions that require a prescription. An OTC device, by definition, doesn’t come with one. If the exemption language ties relief to a prescribed device, the OTC model may be fully taxed. Before you buy, read your state’s exemption language and check whether it says “prescribed” or simply “hearing aids.”
What Still Gets Taxed Even When the Device Doesn’t
A full exemption on the hearing aid itself doesn’t extend cleanly to everything you’ll buy alongside it. This is where receipts stop matching expectations.
Batteries and Accessories
Replacement batteries, cleaning kits, dehumidifiers, and similar accessories are frequently taxed at the full rate. States tend to treat them as consumable goods or general retail merchandise rather than prosthetic devices. The exemption is for the core device, not the supplies that keep it running.
Some states do exempt batteries when a licensed hearing aid dispenser sells them as part of the original device package. Once you’re buying replacements at a drugstore or online, expect tax. Accessories follow the same pattern: bundled in the box with an exempt device, possibly covered; bought separately, almost always taxed.
Repairs and Replacement Parts
Repair bills have two potential tax pieces: labor and parts. Many states don’t tax services at all, so the labor portion of a repair is often tax-free. Replacement components installed during the repair may still be taxable as tangible personal property, depending on how the state treats goods transferred during a service transaction.
Fitting and Audiology Services
Audiology exams, fittings, and ear mold impressions are generally not subject to sales tax because they’re professional services rather than sales of goods. That holds even in states that tax the device itself.
A practical note: if the provider lumps the fitting fee into the device price on one invoice line, the whole amount can be treated as a taxable product sale in states where the device isn’t exempt. Ask for an itemized bill that separates service charges from the device.
How to Confirm the Tax at Your Address
Your provider is legally responsible for collecting the correct tax and should be able to explain the treatment in your area. Ask for a written breakdown showing the tax calculation before you sign. Providers do occasionally get it wrong, and on a purchase this size a second look is worth the time.
The authoritative source is your state’s Department of Revenue website. Look for administrative rules, tax bulletins, or advisory opinions covering prosthetic devices or durable medical equipment. These documents lay out which items qualify and under what conditions. For an OTC device, focus on whether the exemption language specifies a prescribed device or just refers to hearing aids.
Check for local add-ons too. A county or municipal tax can appear on the receipt even when the state exempts the device. Most state tax agencies publish a rate lookup tool where you can enter your address and see the combined rate that applies to taxable goods at that location.
Other Ways to Lower the Cost
Sales tax isn’t the only lever. Federal tax rules give you a few more, regardless of how your state treats the sale.
HSAs and FSAs
Hearing aids and their batteries are eligible medical expenses for a health savings account or a health care flexible spending account. Paying with pre-tax dollars effectively discounts the purchase by your marginal tax rate. For 2026, the HSA contribution limit is $4,400 for self-only coverage and $8,750 for family coverage.4Internal Revenue Service. Revenue Procedure 2025-19 The health care FSA limit for 2026 is $3,400.5FSAFEDS. New 2026 Maximum Limit Updates
If you know a purchase is coming, building up the balance in advance is straightforward. HSA funds roll over indefinitely. FSA funds usually have to be spent within the plan year, though some employers offer a grace period or a limited carryover.
Medical Expense Deduction
The IRS treats hearing aids, batteries, repairs, and maintenance as deductible medical expenses.6Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses Claiming it means itemizing on Schedule A, and only the portion of total medical expenses above 7.5% of your adjusted gross income counts.7Internal Revenue Service. Topic No. 502, Medical and Dental Expenses Ordinary medical costs often don’t clear that floor on their own. A hearing aid purchase in the same tax year as other significant medical bills can push you over it.
A Note on Medicare
Original Medicare Parts A and B do not cover hearing aids or the exams for fitting them.8Medicare. Hearing Aid Coverage Some Medicare Advantage (Part C) plans include a hearing benefit, but the base program does not. For anyone on original Medicare, the sales tax question and the HSA, FSA, and deduction paths above carry more weight.
