Veterinary Practices Bookkeeping in New Mexico

A veterinary practice in New Mexico sells three things the New Mexico Taxation and Revenue Department treats differently: professional services, dispensed medication, and retail product such as food, supplements, and supplies. Retail is squarely taxable at 4.875% plus local; professional services generally are not; medication sits between them and depends on how it is dispensed. The Gross Receipts Tax falls on the seller and covers most services, so service businesses that would be exempt elsewhere are taxable here. A practice running everything through one revenue account cannot produce a defensible return, and the fix is at the point-of-sale level — the categories have to exist in the system that rings up the sale, not be reconstructed monthly from a spreadsheet.

Prescription medication is treated more favourably than general merchandise in most sales tax states, but the boundaries for veterinary use are narrower than people assume — a drug dispensed under prescription and the same drug sold over the counter can carry different answers, and prescription diets and supplements frequently sit on the taxable side of the line. New Mexico sets its own scope through the New Mexico Taxation and Revenue Department. The bookkeeping consequence is that drug inventory needs categorising by how it is sold rather than by what it is, which is also what makes expiry and controlled-substance tracking workable.

Employer registration in New Mexico runs through the New Mexico Department of Workforce Solutions, a different agency from the New Mexico Taxation and Revenue Department that handles your sales tax — a separate account number, a separate login, and separate deadlines. Standing with one says nothing about standing with the other, and for veterinary practices the first sign of a gap is usually a notice rather than a reminder. Your unemployment insurance rate is set by the New Mexico Department of Workforce Solutions from your own claims history, which means it is a cost you can actually influence — and one that quietly changes each year while the payroll journal entry stays the way somebody set it up.

The New Mexico statewide base rate is 4.875%. That sits mid-table nationally, with local rates layered on top and sourced to the delivery address rather than to your own location. Sourcing is where this is won or lost, and with economic nexus set at $100,000 in sales, it becomes your problem the moment that threshold is crossed.
