Learn moreAn elevated county property tax rate
McKinley County's effective property tax rate ran approximately 1.20% to 1.26% depending on source -- above both the national median (~1.02%) and New Mexico's own statewide median, with Gallup itself cited as the county's highest local rate.
New Mexico's real, graduated income tax
New Mexico taxes income across 6 brackets from 1.5% up to a 5.9% top rate above $210,000 single/$315,000 MFJ for 2026, conforming to the federal standard deduction.
A real, disclosed Social Security hard cliff
New Mexico exempts Social Security only when AGI runs under $100,000 single/$150,000 MFJ -- a hard cliff, not a phase-out -- and other retirement income remains fully taxable.
Key takeaways
- McKinley County's effective property tax rate (~1.20-1.26%) runs above national and NM statewide medians.
- New Mexico's 6-bracket 1.5%-5.9% income tax (2026) applies statewide.
- Social Security is exempt only below $100,000 single/$150,000 MFJ AGI -- a hard cliff, not a phase-out.
