Montana's real 2026 income tax rate

Montana's individual income tax runs a two-bracket structure: 4.7% up to $47,500 (single/MFS) or $95,000 (MFJ), and a 5.65% top rate above those thresholds, applying in Fort Benton as statewide (base record).

Fort Benton's genuinely elevated property tax rate

Ownwell cites Fort Benton's effective rate at 1.11% -- the highest of any community in Chouteau County per that source, and above both the national median (1.02%) and Montana's own statewide anchor rate (0.74%) (base record).

A modest median annual tax bill despite the elevated rate

Fort Benton's median annual property tax bill ran approximately $1,895, reflecting the town's genuinely affordable underlying home values even given the elevated rate (base record).

No general statewide sales tax

Montana levies no general statewide sales tax, and Fort Benton is not among the state's narrow list of resort-tax communities (base record).
