What taxes apply to a new small business?

Taxes Applicable to a New Small Business in New Mexico

When starting a small business in New Mexico, understanding the tax obligations is crucial for smooth operations and compliance. Below are the key taxes that typically apply:

• Gross Receipts Tax (GRT): New Mexico does not have a traditional sales tax but imposes a Gross Receipts Tax on the total revenue from business activities. Most businesses must register for GRT and collect it on taxable sales and services. Rates vary by location and type of business.
• Income Tax: Businesses operating as sole proprietorships, partnerships, or LLCs typically report business income on their personal state income tax returns. Corporations must file separate state corporate income tax returns. New Mexico has a progressive income tax system.
• Withholding Tax: If your business has employees, you must withhold New Mexico state income tax from employee wages and remit it to the state. Registering with the New Mexico Taxation and Revenue Department for withholding tax is required.
• Unemployment Insurance Tax: Employers must pay state unemployment insurance taxes to the New Mexico Department of Workforce Solutions. This supports unemployment benefits for eligible former employees.
• Property Tax: If your business owns real property or certain personal property, property taxes may apply. These are assessed at the county level based on the value of the property.

As of 2026, tax rates and filing requirements may change, so regularly review updates from the New Mexico Taxation and Revenue Department and consider consulting with a tax professional for tailored operational guidance.

Operationally, set up bookkeeping systems to track taxable sales, employee payroll, and tax payments. Automating tax calculations and filings can reduce errors and save time. Proper tax registration and timely reporting help avoid penalties and support sustainable business growth in New Mexico.
