Do Dietitians Charge Sales Tax in the US? Two States Do

Is nutrition counseling subject to sales tax?

In two of the states verified, because they tax gross receipts rather than retail sales. Hawaii's general excise tax is "a privilege tax imposed on business activity", levied "on the gross income received by the person engaging in the business activity", and the department lists services among the activities it reaches, at 4 percent plus a 0.5 percent county surcharge where a county has adopted one. Its statutory list of amounts not taxable runs to seventeen paragraphs, covering insurance proceeds, wages, alimony and the like, and none of them exempts health care or professional services. The tax may be visibly passed on to the client but need not be.

New Mexico’s gross receipts tax reaches “performing services in New Mexico”, and its two health-care deductions do not reach a cash-pay dietitian. One deduction defines “health care practitioner” by a closed list of seventeen categories that does not include dietitians or nutritionists, and in any case applies only to receipts from managed-care and insurer contracts. The other names “a nutritionist or dietitian licensed pursuant to the Nutrition and Dietetics Practice Act”, but covers only receipts paid by the United States government, such as Medicare Part B. A client-paid counseling fee falls outside both, so the tax applies to it. No department ruling addressing dietitians specifically was found. What Medicare pays a dietitian, and on what conditions, is in which US insurers cover dietitian services.

South Dakota's sales tax applies to "the sale of services" at 4.2 percent plus municipal tax, but the department's own health-services publication lists "Dietitians" and "Nutritionists" among the licensed practitioners whose health services are exempt from state and municipal tax. West Virginia taxes services generally but excepts "professional and personal services" on the face of the statute, defines neither term, and its exemption bulletin names only doctors, lawyers, engineers, architects and accountants as examples. Whether a dietitian is inside that exception is unresolved. Delaware has no sales tax but imposes a gross receipts tax on the seller of goods and services at rates from 0.0945 to 1.9914 percent, with monthly exclusions that "generally start at $100,000". The specific classification for a dietitian was not determined.

Ten states were verified individually not to tax the session at all: South Dakota, above, and these nine. Texas taxes only sixteen enumerated service categories, and "personal services" there means massage parlors, Turkish baths and escort services. Connecticut's list runs from (A) to (QQ) with no nutrition or health-care entry. Iowa and Minnesota enumerate "reducing salons" and "health clubs" as facilities, not counseling. New Jersey's own guide marks professional services exempt. Pennsylvania taxes a closed list of eleven service types and expressly excludes "human health-related services" from its help-supply category. New York exempts services unless enumerated. Ohio's nearest entries are physical-fitness facilities and "personal care service", defined as grooming and body services. California treats a service provider as the consumer of what it uses and asks what the "true object" of the transaction is. The roughly thirty-five remaining states were not individually verified for this page and are not grouped behind a general statement.

Where are the sales-tax traps for a nutrition practice?

The first is in New York City. New York State exempts services unless enumerated and does not enumerate nutrition counseling, but the state's own quick-reference bulletin lists "services provided by weight control and health salons, gymnasiums, Turkish and sauna baths, and similar facilities" among services "subject only to New York City sales tax". The bulletin does not define a weight-control salon. Whether a Manhattan practice that brands itself around weight management falls inside the phrase is unresolved, and it should not be answered without a professional opinion or a state advisory opinion.

Washington moved the line in 2025. Its retail-sale definition now includes "live presentations including, but not limited to, lectures, seminars, workshops, or courses where participants attend either in-person or via the internet", effective October 1, 2025, and expressly excludes "one-on-one instructional activities including tutoring and consulting". A dietitian's paid group webinar is on the taxable side of that line and the same dietitian's individual session is not. A separate subsection of the same statute expressly excludes "nutritional consulting" from the tax on athletic and fitness facility services, so a practice inside a gym is protected for the consult but not for personal training. Washington also taxes service income under its business and occupation tax with no deduction for costs, at 1.5 percent for a practice under $1,000,000 of prior-year income, offset by a small-business credit of up to $3,840 a year for service-dominant filers.

Four other states contain near-misses that reach a hybrid business rather than a consultation: Iowa's "reducing salons", Minnesota's "reducing salons" and "health clubs", Connecticut's "health and athletic club services" and Texas's "health clubs and fitness centers" as amusement services. None defines the term. The exposure is for a practice that is also a gym, spa or weight-loss salon, not for the counseling itself.

Is a downloadable meal plan or subscription taxable?

A downloadable meal plan is taxed in Washington, Pennsylvania and Connecticut, not in California, and Ohio and New Jersey have not said. Washington taxes digital goods "regardless of whether the purchaser's right of use is permanent, less than permanent … or the purchaser is obligated to make continued payments", and its department's own worked example of a digital book is "a cookbook in a PDF format downloaded or accessed through the internet". Washington does exclude professional services represented in electronic form where the product "primarily involves the application of human effort" begun after the customer asked, which is the exclusion an individualized plan would be argued under. California states directly that "digital books (eBooks) … are generally not taxable when you transmit the data to your customer over the Internet", unless a printed or physical copy is supplied. Pennsylvania taxes books "whether electronically or digitally delivered, streamed or accessed and whether purchased singly, by subscription or in any other manner", and its retailer guide lists e-books and e-book subscriptions as taxable. Connecticut defines digital goods to include "reading materials" and taxes them as tangible property at the full 6.35 percent. Ohio and New Jersey tax a "digital book", defined as a work "generally recognized in the ordinary and usual sense as a book", and neither has said whether a meal plan is one. In New Jersey, a downloaded video course is taxable and the same course streamed is not.

New York and Texas approach the question through "information services" rather than digital goods. New York taxes "collecting, compiling or analyzing information of any kind or nature and furnishing reports thereof", excludes information "personal or individual in nature", and then reads the exclusion narrowly: output "created or generated from a common database" or from "statistical models or historical data" is taxable "even when applied to the client's own data", and "newsletter subscriptions" are on the taxable list. A plan generated from a recipe and nutrient database arguably falls on the taxable side. One reflecting individual clinical judgment arguably does not. Texas taxes information "made available … to the public or to a specific segment of industry", lists newsletters as an example, collects tax on 80 percent of the charge, and excludes information "gathered or compiled on behalf of a particular client" that is proprietary to that client and may not be resold. Texas has published nothing applying either rule to nutrition plans. Illinois taxes tangible personal property at state level and its department's overview does not reach digital goods, but Chicago separately taxes "nonpossessory computer leases", which is how the city reaches hosted subscriptions, with an exemption for content that is "primarily proprietary".

Are supplements and food products taxable when a dietitian sells them?

It depends on the state, and the common claim that supplements are always taxable is wrong in New York and Texas. New York's bulletin states that exempt food "includes products that are used as dietary foods and health supplements" regardless of form, listing herbal, mineral and antioxidant supplements, protein powders, protein bars and multivitamins as exempt, while taxing sports and energy drinks and flavored waters. Texas states that "dietary supplements are not taxable", using a Supplement Facts panel test, but excludes CBD products and taxes individually portioned protein, nutrition and granola bars as snack items. Washington, California and Pennsylvania tax supplements. Washington carves them out of the grocery exemption using a three-part definition ending in a required Supplement Facts box, while treating meal-replacement products labeled with a Nutrition Facts box as exempt food. California's regulation names "protein supplements and vitamin pills" as taxable. Pennsylvania lists "food supplements and substitutes" as taxable alongside exempt groceries.

Selling anything into another state raises the separate question of economic nexus. Since the Supreme Court overruled the physical-presence rule in 2018, each state sets its own threshold, and the bases differ in a way that matters for a practice selling downloads. South Dakota's is $100,000 of gross sales "including products delivered electronically", with no transaction-count prong. Texas's $500,000 safe harbor counts "gross revenue from taxable and nontaxable sales of tangible personal property and services". California's $500,000 and New York's $500,000-and-100-sales tests both count tangible personal property only, so a seller of only electronic products may never cross them. Illinois uses $100,000 or 200 transactions, again measured on tangible property.

Which local business taxes apply to a solo dietitian practice?

Six cities' business taxes reach a solo practice: Los Angeles, San Francisco, Philadelphia, New York City, Portland and Seattle. Several of the figures in circulation for them are out of date. Los Angeles requires every business to obtain a tax registration certificate and taxes "professions and occupations" at $4.25 per $1,000 of gross receipts, with a small-business exemption up to $100,000 of worldwide receipts that applies only to registered businesses that file their renewal on time. The first year is not exempt and is paid as "back tax" in year two. San Francisco requires registration "regardless of whether the business or person is subject to taxation", within 30 days of commencing. Its gross receipts tax filing threshold rose to $5,000,000 for 2025 under Proposition M, from $2,250,000 the year before.

Philadelphia's business income and receipts tax reaches "every individual, partnership, association, limited liability company", at 1.410 mills on gross receipts plus 5.71 percent on net income for 2025, and the city states that "as of tax year 2025, the Philadelphia is no longer permitted to offer the statutory exemption of the first $100,000 in gross receipts". A return is due whether or not there was a profit, and the separate net profits tax, 3.74 percent for residents and 3.43 percent for non-residents, applies to sole proprietors and LLCs but not corporations. New York City's unincorporated business tax has no professions exemption: its instructions state that "income received from the practice of law, medicine, dentistry, architecture, or any other profession is subject to the Unincorporated Business Tax". What shelters a small practice is the $95,000 gross-income filing threshold and a credit that fully offsets liability of $3,400 or less. The rate is 4 percent, and an S corporation election does not escape the city, which taxes S corporations under its general corporation tax instead.

Portland requires registration within 60 days and taxes at 2.6 percent for the city, 2 percent for Multnomah County and 1 percent for the Metro housing tax. The city's exemption threshold is $50,000 through 2025, $75,000 for 2026 and $100,000 from 2027, and the county's is $100,000. Exempt filers must still file. A sole proprietor pays the Metro tax as personal rather than business income. Seattle requires a business license tax certificate of anyone engaging in "any business activity, profession, trade, or occupation", and its service rate and threshold both change in 2026: the rate rises from .00427 to .00658 for 2026 through 2032, while the threshold below which no tax is owed rises from $100,000 to $2,000,000. A return must still be filed under the threshold. Washington State's own business and occupation tax sits underneath all of this, with a $12,000 gross-income registration trigger.

Whether to hold the practice in an LLC changes none of these taxes at federal level and only some at city level: see LLC, PLLC or sole proprietor for a US dietitian. The Canadian counterpart is a single federal question with a statutory boundary: see do dietitians charge GST/HST in Canada. The other decisions that change by state are in the full state-by-state checklist for a new practice.
