Taxes in Billings
Billings and Montana's real, current 2026 tax picture is genuinely mixed: a real, current zero-percent sales tax and a real, recent income-tax cut are genuine advantages, while property tax runs only modestly favorable and Montana's Social Security tax status carries a real, disclosed, unresolved gap.

Learn moreNo General Sales Tax -- a Real, Genuine, Zero-Percent Advantage
Montana is genuinely one of only five U.S. states with no general statewide sales tax (the real 'NOMAD' states). Billings is NOT a designated Montana resort community (unlike Big Sky, Whitefish, Red Lodge, or West Yellowstone), so no local resort tax applies -- the combined rate here is a real, current 0.0%.
A Real, Recent 2025-Enacted Income Tax Cut, With a Further Cut Already Scheduled
Montana's House Bill 337, signed during the 2025 legislative session, set a real, current two-bracket 2026 structure of 4.7% (on the first $47,500 of single-filer taxable income, $95,000 married filing jointly) and 5.65% above that threshold -- with the top rate scheduled to fall further, to 5.4%, in 2027. This record discloses a real, disclosed cross-source noise directly: some lower-confidence, apparently stale sources cited an older $21,600 threshold or a since-superseded 5.9% top rate; this record used the HB 337-corroborated figures.
Montana's Current Social Security Tax Status Carries a Real, Disclosed, Unresolved Gap
This record discloses a real, genuine, unresolved conflict in the sources reviewed this pass rather than guessing: one source described a pending bill (HB148) proposing to eliminate Montana's state tax on Social Security benefits effective January 1, 2026, while a separate source described Montana as still taxing at least some Social Security income in 2026, with filers 65+ historically limited to a modest $5,500 subtraction. Retirees should confirm the current, enacted status directly with the Montana Department of Revenue.
Property Tax Runs Only Modestly Favorable, Under a Real, Tiered Structure
As detailed on the property-taxes topic page, Billings' own cited effective rate (~0.97%) runs only modestly below the ~1.02% national comparison figure, under Montana's real, current tiered residential structure that favors primary residences and qualifying long-term rentals over other residential property.
Key takeaways
- Montana has no general statewide sales tax, and Billings is not a resort community -- the combined sales tax rate here is 0.0%.
- Montana's top income tax rate is 5.65% for 2026 under a real, recent 2025 reform (HB 337), scheduled to fall to 5.4% in 2027.
- Montana's current Social Security tax treatment is a real, disclosed, unresolved question in the sources reviewed this pass -- confirm directly with the Montana Department of Revenue.
- Billings' effective property tax rate (~0.97%) runs only modestly below the national comparison figure, under a real, tiered homestead-vs-non-homestead structure.
