What is the difference between GRT and sales tax?
The fundamental difference is who owes the tax. Sales tax is legally imposed on the buyer. The business just collects it and passes it to the state. Gross Receipts Tax is imposed on the business itself for the privilege of doing business in New Mexico.
This sounds like a technicality, but it changes things in practice.
With sales tax, you collect a percentage on top of your price and that money was never yours. You’re essentially holding it for the state. With GRT, the tax is calculated on what you receive, and it’s your obligation to pay. You can choose to pass that cost to customers by adding it to your invoice, or you can absorb it as a cost of doing business. Most businesses pass it along, but they’re not required to.
The tax base is also different. Traditional sales tax typically applies to physical goods. Services are often exempt. New Mexico’s GRT applies to almost everything, including most services. Lawyers, consultants, contractors, and accountants all pay GRT on their revenue. If you’re used to operating in a sales tax state where your services weren’t taxed, this is a significant adjustment when you start doing business here.
Rates vary by location throughout the state. The state portion is consistent, but counties and municipalities add their own portions. A business in Santa Fe pays a different rate than one in Albuquerque or Taos. And if you’re doing work in multiple locations, the rate that applies depends on where the service is delivered, not where your office is located. Contractors working on projects across Northern New Mexico deal with this constantly.
For bookkeeping purposes, GRT requires tracking gross receipts by location if you work across different tax jurisdictions. You need to know not just how much you brought in, but where that revenue was earned. This affects how your books are structured and how GRT returns get prepared each month.
The reporting itself is different too. You’re reporting your taxable gross receipts, not a separate line item for tax collected. If you’ve set up your books expecting traditional sales tax treatment, you’ll need to adjust how you track and categorize things.
Many business owners who relocate to New Mexico or start their first business here get confused by GRT because they’re expecting something that works like sales tax. It’s close enough to seem familiar, but different enough to cause problems if you treat it the same way. Getting your bookkeeping services in Santa Fe set up correctly from the start saves headaches when filing deadlines arrive.
