New Mexico uses a graduated individual income tax and a top rate of 5.9%. There is no local (city/county) income tax on top of the state rate. No state estate or inheritance tax applies. Source: Tax Foundation — State Individual Income Tax Rates and Brackets, 2026 (retrieved 2026-08-11).
Why it matters: State income tax is only part of the picture. Residency, sourcing of income, credits, and local taxes change the effective burden. Use the embedded estimator below for your own number, and check reciprocity and convenience-rule status before a move or remote-work arrangement.
