Corporate and Individual Income Tax Rates
Knudsen Law Firm, PLLC assists clients in navigating Montana’s corporate and individual income tax regulations to optimize their tax position and business structure.
Montana imposes a flat 6.75% corporate income tax rate on all taxable income without brackets. Individual income follows progressive rates, with 4.7% applied to income up to $21,100 (single filers) or $42,200 (joint filers), and 5.9% on amounts exceeding these thresholds. While Montana levies a traditional corporate income tax, six states have chosen alternative approaches by imposing gross receipts taxes either instead of or in addition to corporate income taxes.
Key considerations for tax planning with Knudsen Law Firm:
- Pass-through entity structuring to avoid the 6.75% corporate rate and utilize individual rates
- Strategic capital gains planning to maximize the 3.0% preferential treatment on the first $21,100
- Navigation of Montana’s non-conformity with federal NOL deductions to ensure compliance
Our experienced attorneys provide comprehensive guidance on business structure selection to minimize your tax obligations and maintain compliance with state regulations.

Small Business Tax Deductions and Relief Programs
At Knudsen Law Firm, PLLC, we help businesses maximize their Montana tax benefits through the state’s 20% small business tax deduction, enabling eligible clients to deduct up to 20% of qualified business income from taxable earnings.
We specialize in assisting pass-through entities like S-corporations, partnerships, and sole proprietorships, where business income flows directly to personal tax returns at individual rates rather than corporate tax rates.
Our experienced tax attorneys work to combine federal tax relief programs with Montana’s deductions to create substantial savings opportunities, ensuring proper eligibility compliance and documentation with the Montana Department of Revenue.
20% Business Income Deduction
As a trusted Montana tax law firm, Knudsen Law Firm, PLLC guides small business owners in leveraging the 20% business income deduction to reduce their tax burden. This deduction targets pass-through entities and individual filers, reducing your effective tax rate from a combined top marginal rate of 45.5% to more competitive levels. Our experienced attorneys assist with documentation requirements and qualifying business structures like sole proprietorships, partnerships, or S corporations.
The business income deduction impacts are substantial:

- 136,000+ small businesses statewide depend on this relief

Pass-Through Entity Benefits
Knudsen Law Firm’s expertise in pass-through entity structure reveals substantial tax advantages that complement the 20% business income deduction discussed previously. When evaluating pass through taxation considerations, our tax attorneys demonstrate how partnerships, S corporations, and LLCs provide income that flows directly to your personal return, avoiding double taxation at the entity level.
Our firm’s tax specialists recommend including Montana’s elective Pass-Through Entity Tax (PTET) in your entity selection criteria, which allows you to pay 6.75% tax at the entity level rather than on your individual return. This election effectively circumvents the federal SALT deduction cap of $10,000, providing significant tax relief. Knudsen Law Firm assists clients with filing Form PTE annually and making quarterly estimated payments through Montana’s Taxpayer Access Portal, ensuring compliance while maximizing your tax benefits.

Benefits of No Sales Tax and Franchise Tax

Companies can streamline their operations by eliminating administrative responsibilities related to sales tax collection, reporting, and remittance, while maintaining straightforward pricing strategies without complex tax calculations.

The elimination of franchise tax requirements based on capital or net worth reduces operational expenses, allowing companies to preserve capital for business growth, as our tax law experts frequently counsel.
These tax advantages make Montana particularly attractive for businesses selling high-value items, providing a competitive edge against businesses in tax-bearing states. Furthermore, companies can avoid investments in tax compliance software and specialized tax consultation fees, enabling greater focus on core business operations.
