Dietitian & nutrition practice bookkeeping: exempt counselling, taxed everything else

One credential decides what is exempt

Only a "dietetic service" delivered by a Registered Dietitian regulated by the College of Dietitians of Ontario qualifies for the GST/HST practitioner exemption. The identical-sounding advice given by a non-RD coach — "nutritionist" is not a protected title in Ontario — is a taxable supply of consulting or coaching, even when the session looks the same from the client's chair. A practice that employs both RDs and non-RD coaches needs revenue accounts split by practitioner credential first, and by service type second, because the credential is what the tax status actually turns on. A practice built entirely around one RD's own counselling can stay simple for years; the moment a second practitioner joins, or the RD starts selling a group program alongside 1:1 visits, the chart of accounts needs to grow with it.

Programs sold in advance are a liability until delivered

Multi-week online programs, meal-plan packages, and memberships paid upfront belong in a deferred revenue account and get recognized as income only as sessions are delivered or the program period passes — the same principle as any prepaid service business. Recognizing the full amount at the moment of sale overstates income in the launch month and understates it in every month that follows, which is exactly the pattern that makes a growing program business look like it is shrinking on paper. Practice-management platforms built for this niche, such as Practice Better, can track program starts and durations directly, which makes the deferral schedule a data pull rather than a spreadsheet built from memory. Payment processor fees on a program launch also need their own line: a card processor's percentage cut is a real cost of the sale, and netting it silently against revenue makes a launch look less profitable than the underlying program actually is once the true cost is separated out.

Supplement inventory needs its own count

Supplements and retail products carried for resale are inventory, not a pass-through expense, and need a cost-of-goods-sold treatment separate from service revenue: units counted on hand, a purchase cost per unit, and a margin that is visible line by line rather than blended into "other income." A practice that treats supplement purchases as a straight expense when bought, rather than as inventory until sold, ends up with a distorted month whenever a large restock lands — a healthy sales month can look like a loss simply because the shelf was restocked in the same period.

Corporate wellness contracts are taxable even when an RD delivers them

The exemption applies to a dietetic service rendered to an individual for their own health. A wellness contract invoiced to an employer for a workshop series delivered to its staff is a supply made to the corporation, not to the individual attendees, so CRA generally treats that revenue as taxable regardless of whether the person delivering it is an RD. Track corporate contracts in their own account from the proposal stage, because retrofitting HST onto a signed annual contract after the fact is a far harder conversation with a client than pricing it in from day one.

Insurer receipts work differently here than in other clinics

Most extended-health plans reimburse for services described as "Registered Dietitian," and unlike clinics that bill an insurer directly on assignment, most nutrition-practice clients pay at the time of the appointment and submit their own receipt for reimbursement. The practice's job is a correctly worded receipt — the RD's registration number, the service description, the date — rather than an insurer reconciliation. Where a practice does direct-bill a benefits provider or a corporate client, that balance should be aged and chased like any other receivable, not left to a member's memory of what was agreed.
