When you sell a business in New Mexico, the gain is taxed as ordinary income at up to 5.9 percent for 2025. Without a state tax clearance the buyer inherits your unpaid taxes, so it holds part of the price in trust; the department answers within 30 days.
New Mexico has fewer employer businesses than most states. The state takes a meaningful share of the gain, 5.9% at the top, with part of a long-term gain excluded. Expect a tax on the business itself on the way out, and a tax-clearance or bulk-sale notice before closing.
Tax on the gain: Part of a gain is deductible.

Capital gains are taxed as ordinary income under a graduated schedule whose top rate is 5.9 percent.
Under HB 252 (2024) New Mexico restructured its brackets for 2025, adding a 4.3 percent bracket and widening the lower ones; the 5.9 percent top rate was left untouched.
The rate is the state's top rate on the gain for the year shown, the same figure as the indicator in the hero, so the two can never disagree.

The rules of the sale
Successor liability is the trap: without a state tax clearance the buyer inherits the seller's tax debts, so expect an escrow.
A buyer of business assets inherits the seller's unpaid gross receipts, withholding and corporate taxes unless it obtains a tax clearance from Taxation and Revenue.

To get that clearance the buyer holds enough of the price in trust to cover any tax due; the department answers within 30 days of a complete request.
