Florida residents pay 0% state income tax. The figures above run each income through Montana's 2026 individual income tax brackets for a single filer, after the state's standard deduction and before credits (California figures use the latest published 2025-indexed brackets).

Key Tax Facts: Montana

What you need to know about Montana's tax environment before making your move.

Montana's top marginal individual income tax rate in this 2026 wage-income comparison is 5.65%. Deductions, taxable-income thresholds and credits affect the amount actually paid.

Montana does not have a state estate or inheritance tax.

What this Montana comparison includes

The comparison models a full year of wage income for a single filer in Montana. A top marginal rate is not the rate paid on every dollar. A move during the year, continuing Montana-source income, credits and local taxes can change the result.

Tax data used: 2026 schedule. Tax Foundation 2026 State Individual Income Tax Rates and Brackets (HB 337, 2025: top rate 5.65% in 2026, 5.4% scheduled 2027)
Single-filer standard deduction in the model: $16,100 before any modeled income-based reduction. Personal exemptions and credits are separate; this figure is not a filing threshold.

Establishing Florida domicile does not automatically end another state's statutory residency or source-income rules. Keep a dated move record, a travel calendar and records of income connected with your former state. A mailing address or declaration alone does not determine tax residency.

Check current guidance from Montana Department of Revenue. Check why tax may remain due after moving.

Montana: match each spouse to the residency schedule

Montana taxes part-year residents on income received during Montana residence plus Montana-source income during nonresidence. Its guidance also addresses couples with different residency statuses and the Nonresident/Part-Year Resident Schedule. Prepare each spouse’s dates and sources separately, then apply the current filing-status instructions. A joint federal return does not make the underlying residence facts identical.
