Tax Attorney in Montana

Federal IRS representation for Montana taxpayers — audits, back taxes, liens, levies, Offer in Compromise filings, and U.S. Tax Court petitions. Montana operates a two-bracket personal income tax of 4.7% and 5.9% (the consolidated structure that took effect under SB 121 of 2021), a 6.75% flat Corporate Income Tax, and one of the rarest tax footprints in the country: no general state sales tax. The state instead funds itself through income tax, severance taxes on coal and oil, ad valorem property tax, and a limited-option resort tax in tourism towns such as Big Sky, Whitefish, West Yellowstone, and Red Lodge. Yellowstone and Glacier tourism, Bakken-edge oil work around Sidney and Glendive, wheat and cattle production across the Hi-Line, Malmstrom Air Force Base contracting in Great Falls, and tribal-economy work on the Blackfeet, Crow, Northern Cheyenne, Flathead, Fort Belknap, Fort Peck, and Rocky Boy's reservations drive the case patterns we see. Our team handles the federal side and coordinates with state and tribal counsel where matters overlap.

If you owe back taxes in Montana, here is what shifted in 2026

The IRS resumed full passport-revocation referrals under IRC §7345 for taxpayers whose seriously delinquent federal tax debt sits above the inflation-adjusted threshold (currently $62,000 for 2026). Montana residents who travel internationally — Malmstrom Air Force Base contractors out of Great Falls, ConocoPhillips and Calumet refinery personnel in Billings and Laurel, Bakken-edge oilfield engineers around Sidney and Glendive, Yellowstone and Glacier outfitters with off-season foreign work, and University of Montana and Montana State faculty with cross-border research portfolios — face real revocation exposure. On the state side, Montana SB 121 (2021) consolidated the prior seven-bracket personal income tax into a two-bracket structure of 4.7% and 5.9% for tax years 2024 and forward, and the Montana Department of Revenue continues to align its state filing more tightly with federal taxable income under Mont. Code Ann. Title 15, Chapter 30. Montana still imposes no general state sales tax, which keeps the entire tax-debt conversation focused on income, payroll, severance, and property — acting before a federal levy or a Montana Statement and Demand lands is materially easier than reversing it after.

What this page covers and why state-specific representation matters in Montana

Victory Tax Lawyers, LLP is a California-licensed tax-law firm whose primary practice is federal IRS resolution. We represent Montana individuals and businesses before the Internal Revenue Service, the U.S. Tax Court, and the IRS Independent Office of Appeals through a Form 2848 Power of Attorney, which is recognized in every IRS district nationwide. Federal tax practice is not constrained by state-bar admission; under 31 CFR §10.3 (Circular 230), attorneys, CPAs, and enrolled agents may represent taxpayers before the IRS regardless of the taxpayer's state of residence.

Montana stacks an unusual mix of tax layers that interact with a federal IRS case. Individuals owe federal income tax to the IRS and a two-bracket 4.7% / 5.9% state income tax to the Montana Department of Revenue under Mont. Code Ann. Title 15, Chapter 30, with the top 5.9% bracket beginning at roughly $20,500 of taxable income for single filers in 2024 (the threshold is indexed annually). Businesses face a 6.75% flat Corporate Income Tax under Mont. Code Ann. §15-31-121. Montana imposes no general state sales tax — one of only five states in the country with that posture — though local-option resort taxes apply in qualifying tourism communities such as Big Sky, Whitefish, West Yellowstone, Red Lodge, Cooke City, Virginia City, and St. Regis, capped at 3% under Mont. Code Ann. Title 7, Chapter 6, Part 15. Montana also assesses ad valorem property tax under Title 15, Chapter 6, with reappraisal cycles that have produced sharp recent valuation increases across Gallatin, Flathead, Missoula, and Yellowstone counties.

When state and federal matters intersect — a shuttered oilfield service company in Richland County with unpaid federal payroll trust funds, for instance, or a Bozeman short-term-rental operator with both unfiled federal Schedule E income and unpaid Big Sky resort tax — we coordinate the federal posture while working alongside Montana counsel for Montana Tax Appeal Board matters where required. Tribal-tax questions on the seven reservations within Montana sit at a separate intersection: federal IRS authority generally reaches tribal members on income earned off-reservation, but on-reservation income for enrolled members working for tribal employers can be exempt from federal withholding under specific treaty and statutory frameworks. If your problem is federal, you do not need an attorney admitted in Montana. You need an attorney admitted somewhere with active U.S. Tax Court bar membership and federal-practitioner credentials under Circular 230. That is what this firm provides.

Your tax rights as a Montana taxpayer

Federal taxpayer rights are codified across the Internal Revenue Code and summarized in IRS Publication 1, the Taxpayer Bill of Rights. They apply identically to a resident of Billings, Missoula, or Havre. The major rights you can invoke in a tax-resolution matter:

Right to representation

Under IRC §7521(b)(2), an IRS examiner or collection officer must suspend an interview if you state you wish to consult with an authorized representative. A signed Form 2848 puts your tax attorney between you and the IRS for the remainder of the matter.

Right to Collection Due Process

After a Notice of Federal Tax Lien (IRC §6320) or a Final Notice of Intent to Levy (IRC §6330), you have 30 days to request a Collection Due Process hearing on Form 12153. CDP requests pause collection enforcement and preserve U.S. Tax Court review.

Right to U.S. Tax Court review

A Notice of Deficiency triggers a 90-day petition window under IRC §6213(a). Filing a petition in Tax Court means you can litigate without paying the deficiency first. Miss the 90 days and your only remedy becomes pay-then-sue in the U.S. District Court for the District of Montana or the U.S. Court of Federal Claims.

Right to an Offer in Compromise

Under IRC §7122, the IRS may accept less than the full liability where doubt as to collectibility, doubt as to liability, or effective tax administration justifies settlement. The offer is filed on Form 656 with Form 433-A(OIC) or 433-B(OIC) financial disclosure.

Right to a Collection Statute

IRC §6502 generally gives the IRS 10 years from the date of assessment to collect, after which the federal debt becomes uncollectible. Several events toll the period: pending OICs, bankruptcy, CDP hearings, and military deployment (relevant for Malmstrom Air Force Base personnel). Pull your IRS Account Transcripts to verify your Collection Statute Expiration Date.

Montana-specific: state assessment window

For state matters, Mont. Code Ann. §15-30-2605 generally limits the Department of Revenue to five years after a return is filed to issue a notice of deficiency for personal income tax, longer for substantial omissions and open-ended for fraud or unfiled returns. The Department's collection authority on a final assessment runs ten years under Mont. Code Ann. §15-30-2629. The federal CSED under IRC §6502 runs separately on its own ten-year clock from the date of federal assessment.

How Victory Tax Lawyers helps Montana taxpayers

Offer in Compromise

We prepare and file Form 656 with the supporting financials under IRC §7122. The IRS evaluates Reasonable Collection Potential (RCP) using your monthly income net of allowable expenses plus the realizable value of assets. We pressure-test the math before submission so the offer reaches Appeals if rejected at intake. For Montana filers, RCP often turns on the Allowable Living Expense table for Gallatin, Flathead, Missoula, Yellowstone, and Lewis and Clark County housing costs — numbers that shift annually. The Bozeman and Whitefish housing markets in particular have generated ALE-to-actual gaps that materially shape OIC math.

Installment Agreement

Streamlined IAs (under $50,000), Non-Streamlined IAs over $50,000 with Form 433-F disclosure, and Partial Pay Installment Agreements under IRC §6159 that run only through the CSED. We pick the structure that fits your facts and your runway.

Lien release and withdrawal

A Notice of Federal Tax Lien under IRC §6321 attaches to your Montana real and personal property and is filed with the clerk and recorder of the county where the property sits — Yellowstone, Gallatin, Missoula, Flathead, Cascade, Lewis and Clark, Lake, Ravalli, Silver Bow, or wherever applicable. We pursue release after payment, certificate of discharge for specific property, subordination to allow refinancing, and withdrawal under the Fresh Start lien-withdrawal program for IAs of $25,000 or less.

Levy release

Wage levies (CP90 / LT11 series) and bank levies under IRC §6331 stop when we secure CNC status, an accepted IA, an accepted OIC, or a CDP request. Time matters: bank levies hold for 21 days before remittance under IRC §6332(c).

Audit and exam defense

Correspondence audits, office exams, and field audits. We respond to Information Document Requests, attend the audit in your place under Form 2848, prepare the Form 4549 protest if we disagree with proposed adjustments, and take the case to the IRS Independent Office of Appeals if needed. Montana audits frequently target Schedule F farm income, oilfield-services Schedule C deductions, short-term-rental Schedule E reporting, and outfitter and guide gross-receipts reconciliation.

Penalty abatement

First-Time Penalty Abatement administrative relief and Reasonable Cause requests under IRC §6651. Common reasonable-cause arguments for Montana filers include hard-winter ranch losses, severe wildfire seasons that displaced households across western Montana, serious illness in remote-county settings where local preparer access is thin, and reliance on a preparer (subject to the Boyle rule that signature-deadline rules cannot be delegated).

12 types of Montana tax issues we handle

Federal IRS practice areas, with Montana-specific framing where relevant.

Unfiled federal and Montana returns

Montana filers who skip a federal 1040 almost always skip the Montana Form 2 with the Department of Revenue. We reconstruct prior years using Wage and Income Transcripts, then file federal first and coordinate the state return to follow. Montana imposes its own failure-to-file penalty under Mont. Code Ann. §15-30-2641.

IRS audit defense

Correspondence, office, and field audits. We respond, document, and protest examination changes through Appeals or the United States Tax Court.

Trust Fund Recovery Penalty

Under IRC §6672, the IRS pierces the corporate veil for unpaid payroll trust funds. Oilfield-service-company closures around Sidney, Glendive, and Baker, plus restaurant and outfitter failures in the Yellowstone and Glacier corridors, produce a recurring Montana TFRP caseload — owners and check-signers face personal assessment.

Wage and bank levies

CP90 / LT11 final notices, bank account levies on accounts at First Interstate, Stockman Bank, Glacier Bank, and the local credit unions, and accounts-receivable levies on Montana business owners and W-2 employees alike.

Federal tax liens on Montana property

NFTLs filed with Montana county clerks and recorders cloud title on homes in Yellowstone, Gallatin, Missoula, Flathead, Cascade, Lewis and Clark, Lake, and Ravalli counties, as well as ranchland in eastern Montana, lakefront property around Flathead Lake, and short-term-rental inventory in the Bozeman, Big Sky, and Whitefish markets.

Passport revocation defense

IRC §7345 certifications to the State Department. We work to decertify before travel for Malmstrom Air Force Base contractors, ConocoPhillips and Calumet refinery personnel, Bakken-edge oilfield engineers, Yellowstone and Glacier tour operators with off-season foreign work, and University of Montana and Montana State faculty with international research obligations.

Offer in Compromise filings

Doubt as to Collectibility OICs for Montana filers with limited equity, often paired with Currently Not Collectible status during processing. Ranch land asset valuation is a recurring OIC issue — the IRS asks for quick-sale value, not appraised market.

Innocent Spouse Relief

Form 8857 relief under IRC §6015. Montana is a common-law (not community-property) state, so federal joint-and-several liability does not automatically pull in the other spouse's premarital separate assets, but joint federal returns still create joint federal exposure at the IRS level.

FBAR and offshore disclosure

FinCEN Form 114 for Montana residents with foreign accounts — cross-border ranching families with Canadian holdings near the Hi-Line, Yellowstone outfitters with overseas client deposits, retired international personnel relocated to Flathead and Bitterroot valleys, and Bozeman tech founders with foreign-formation entities.

U.S. Tax Court petitions

Deficiency petitions filed within 90 days of the Notice of Deficiency, with Montana trial sessions historically held in Helena and occasionally Billings. Sessions use non-permanent courtrooms; the specific address is published in the notice of trial.

Self-employment back taxes

Montana has a deep 1099 contractor base — ranch hands and seasonal ag labor across the Hi-Line, Yellowstone and Glacier outfitters and fishing guides, framing and trades contractors across the Gallatin and Flathead valleys, locum-tenens physicians serving rural critical-access hospitals, and Bozeman tech freelancers. Unpaid SE tax under IRC §1401 compounds quickly.

Cryptocurrency reporting issues

Bozeman's tech corridor and Missoula's growing remote-work population produced an active crypto-trading cohort. We address unreported gains, Form 1099-DA exposure, and John Doe summons defense.

Nine common causes of tax debt in Montana

1. Oilfield boom-bust cycles

Bakken-edge work around Sidney, Glendive, Baker, and Wibaux pays high 1099 income in upcycles and zero in downcycles. Quarterly estimates rarely keep pace. When the rigs idle, the April balance lands on a household that has already shifted to unemployment and savings burn.

2. Small-business payroll lapses

A Montana LLC stops depositing 941 trust funds during a slow off-season. The IRS asserts TFRP against the owner personally under IRC §6672. The state side becomes a Montana Department of Revenue withholding inquiry and, often, a Montana Department of Labor and Industry unemployment-contribution audit.

3. Wildfire disaster years

Severe western-Montana fire seasons displace households and shutter outfitters, sawmills, and lodging operators for weeks at a time. Estimated payments slip, insurance proceeds get misclassified, and casualty-loss deductions go unclaimed. The IRS may grant disaster-relief extensions under IRC §7508A, but extensions do not automatically waive penalties on amounts already past due.

4. Sold real estate without 1031

Bozeman, Whitefish, and the Flathead and Bitterroot valleys saw real-estate appreciation that ran multiples of national averages. Investment-property and ranch sales without a like-kind exchange under IRC §1031 triggered surprise capital-gains balances on the federal 1040 and the Montana Form 2.

5. Misclassified worker disputes

IRS audit reclassifies 1099 contractors as W-2 employees. Retroactive payroll-tax assessment lands on the Montana employer, often paired with a Montana Department of Revenue withholding inquiry and a Montana Department of Labor and Industry Independent Contractor Central Unit determination.

6. ERC clawback exposure

Employee Retention Credit claims submitted by promoter mills are being clawed back through CP207/CP207L letters. Montana restaurants, dental practices, hospitality and lodging operators, and small outfitting businesses face the audit wave.

7. Short-term-rental income gaps

Bozeman, Big Sky, Whitefish, Red Lodge, and West Yellowstone short-term-rental operators frequently underreport Schedule E or Schedule C revenue, miss material-participation tests, and skip resort-tax remittance. The IRS now receives Form 1099-K data from VRBO, Airbnb, and Vrbo at the $600 threshold, which has produced a wave of CP2000 underreporter notices.

8. Healthcare locum 1099 income

Montana's critical-access hospitals — from Glasgow and Glendive in the east to Libby and Polson in the west — rely heavily on locum-tenens physicians, CRNAs, and traveling nurses earning 1099 income across multiple states. Quarterly estimates slip and a six-figure April balance lands.

9. Ranch and farm income

Hi-Line wheat, central-Montana hay, and eastern-Montana cattle and sheep operators manage lumpy income against equipment depreciation, Schedule F deductions, Section 179 elections, and CRP payments. Drought years and herd-sale years produce recurring federal balances, often paired with unfiled state returns.

Who is on the hook: eight tax-liability scenarios

Joint filers

Joint federal returns create joint-and-several liability under IRC §6013(d)(3). One spouse can be pursued for the entire balance. Innocent Spouse Relief under IRC §6015 is the principal escape valve. Montana is a common-law (separate property) state, so federal joint liability does not automatically reach the other spouse's premarital property the way it does in community-property states — but joint federal returns waive that distinction at the federal level.

Responsible persons for payroll

Trust Fund Recovery Penalty under IRC §6672 reaches anyone who had check-signing authority and willfully failed to pay over withheld taxes — not just officers. Bookkeepers, controllers, and managers in Montana oilfield-services, outfitting, restaurant, and lodging operations have all been assessed.

Montana corporate income tax

The 6.75% flat Corporate Income Tax under Mont. Code Ann. §15-31-121 is the entity's liability and is filed on Montana Form CIT. A $50 minimum applies even to inactive C corporations under Mont. Code Ann. §15-31-122. Pass-through entities file Montana Form PTE for the entity-level information return; the owner's federal-conformed income flows through to the individual Montana return.

Transferee liability

IRC §6901 reaches a transferee of assets where the transfer rendered the transferor insolvent and tax debts remain unpaid. Montana ranch-succession transfers, family-LLC restructurings, and outfitter business sales can trigger this exposure when the predecessor leaves behind unpaid federal balances.

Montana resort-tax personal liability

Resort communities approved under Mont. Code Ann. Title 7, Chapter 6, Part 15 collect a local-option sales-style tax of up to 3% on lodging, prepared food, and retail in qualifying tourism communities — Big Sky, Whitefish, West Yellowstone, Red Lodge, Cooke City, Virginia City, St. Regis, and several others. Collected resort tax is a trust fund of the local government, and personal-responsibility statutes within the authorizing ordinances commonly reach officers and members who fail to remit. There is no general state sales tax in Montana under mtrevenue.gov guidance.

Successor business liability

Asset purchases where the buyer continues the seller's operations can carry forward IRC §6324 estate-tax liability and analogous successor exposure for income tax. Montana imposes successor obligations for unpaid state withholding under Mont. Code Ann. §15-30-2614, and a buyer acquiring a Montana business should obtain a tax-clearance letter from the Department of Revenue before closing.

Nominee and alter-ego

The IRS files a nominee or alter-ego lien when assets titled in another's name actually belong to the taxpayer. Common in Montana holding-company structures where the operating LLC carries the tax debt and ranch or lakefront real estate sits in a separate single-member LLC.

Estate and decedent returns

A decedent's final 1040 and the estate's 1041 are the personal representative's responsibility. Personal liability attaches under 31 USC §3713(b) if distributions go out before federal tax claims are satisfied. Montana repealed its separate state estate tax in 2005, so for Montana decedents this is now a purely federal concern at the estate-tax level, though the final Montana Form 2 and Form FID-3 fiduciary return still need to be filed with the Department of Revenue.

What resolution can look like

Debt reduced

An accepted Offer in Compromise settles the federal liability for less than the full amount. Partial Pay IAs cap the recovery at what you can pay through the CSED. Currently Not Collectible status freezes collection.

Penalties abated

First-Time Penalty Abatement removes failure-to-file and failure-to-pay penalties for a clean compliance year. Reasonable-cause requests address wildfire seasons, hard-winter ranch losses, oilfield bust cycles, serious illness, and preparer reliance.

Liens and levies released

An NFTL withdraws once a streamlined IA is in place under Fresh Start. Wage and bank levies release when the underlying account moves to CNC, IA, or OIC processing. Passport certifications reverse once the debt drops below the §7345 threshold.

Outcomes vary. Past results do not guarantee future outcomes. Each tax case is unique.

Settlement ranges from the firm's case files

The following ranges come from Victory Tax Lawyers cases over the past several years and contribute to the firm's $91M+ aggregate tax-relief figure. Names and identifying facts are removed for confidentiality.

Matter type Original liability Resolution Approximate result
Installment Agreement $138,296 IRC §6159 streamlined IA $25/month accepted
Partial Pay IA $126,489 IRC §6159 PPIA through CSED $50/month accepted
Installment Agreement $128,206 IRC §6159 streamlined IA $25/month accepted
Partial Pay IA $116,451 IRC §6159 PPIA through CSED $50/month accepted
Installment Agreement $152,296 IRC §6159 streamlined IA $25/month accepted

Past results do not guarantee future outcomes. Each tax case is unique and turns on facts, asset position, monthly disposable income, IRS Allowable Living Expense tables, and the discretion of the assigned Revenue Officer or Settlement Officer. Acceptance rates for Offer in Compromise vary widely — the IRS reported a nationwide acceptance rate of roughly 30 to 40 percent in recent years.

Why a California-licensed firm represents Montana taxpayers

Federal tax practice is regulated by Treasury under 31 CFR Part 10 (Circular 230). An attorney admitted in any U.S. jurisdiction may represent any taxpayer before the IRS in any state via Form 2848 Power of Attorney. State-bar admission is a state-court question; the IRS is a federal agency, the U.S. Tax Court is a federal court of national jurisdiction, and the IRS Independent Office of Appeals is a federal administrative venue. Montana clients in particular benefit from remote engagement — the state's geographic spread means even local attorneys typically work clients statewide by phone, video, and secure portal.

Parham Khorsandi is a member of the State Bar of California (license #266658) and is admitted to practice before the United States Tax Court — admission to that court is national, not state-bound. Amir Boroumand (Cal Bar #269570) supplements the firm's federal practice.

For matters that require an attorney admitted in Montana — for example, a Montana Tax Appeal Board case that advances to the Montana District Court and then the Montana Supreme Court, or a county-court action attacking a property-tax assessment under Mont. Code Ann. §15-15-103 — we coordinate with Montana counsel and stay engaged on the federal-tax side. Most VTL Montana cases are pure federal practice and do not require Montana-bar representation at all.

The seven steps of a VTL tax-resolution engagement

1

Free consultation

A 30-minute call with an attorney to outline the facts, the IRS notices received, and the realistic resolution options.

2

Engagement letter

A written attorney-client agreement defines scope, fee, and authority. Federal common-law attorney-client privilege attaches.

3

Form 2848 filed

Power of Attorney filed with the IRS Centralized Authorization File so all subsequent IRS notices route to the firm.

4

CAF investigation

Account Transcripts, Wage and Income Transcripts, and Record of Account pulled across all open tax years. CSED dates verified.

5

Strategy memo

A written analysis recommending OIC, IA, CNC, audit response, CDP, or Tax Court petition based on the financial profile.

6

Resolution filed

Forms 656, 433-A, 9423, 12153, or Tax Court Petition prepared and filed. Negotiations with Revenue Officers, Settlement Officers, or Appeals Officers handled directly.

7

Compliance close-out

Post-resolution monitoring: future quarterly estimates, return filings, and protection against IA default. The case is not done when the offer is accepted; it is done when the new pattern is stable.

Collection statute warning — federal and Montana

Under IRC §6502(a), the IRS generally has ten years from the date of assessment to collect a tax. After the Collection Statute Expiration Date, the federal debt becomes uncollectible by operation of law. Several events toll or extend the CSED, including a pending Offer in Compromise (extends by the OIC pendency plus 30 days), bankruptcy filing (extends by the bankruptcy stay plus six months), a Collection Due Process hearing (extends while pending), Innocent Spouse claims, and continuous absence from the United States for six months or more.

On the Montana side, Mont. Code Ann. §15-30-2605 generally limits the Department of Revenue to five years after the return is filed to issue a notice of deficiency for personal income tax, with longer windows for substantial omissions and open-ended periods for fraud or unfiled returns. The Department's collection authority on a final assessment runs ten years under Mont. Code Ann. §15-30-2629, generally tracking the federal ten-year framework but starting from a different event. Withholding-tax assessment and collection follow the same general structure under Title 15, Chapter 30, Part 25.

Before negotiating any resolution, pull your IRS Account Transcripts and verify your CSED dates. Submitting an OIC restarts an already-running clock; sometimes a Partial Pay Installment Agreement that runs out the statute is the better strategy than an offer that extends it.

Montana venue: where federal and state tax matters are heard

Federal tax matters affecting Montana taxpayers proceed in federal venues. State tax disputes proceed through the Montana Department of Revenue administrative-review process and the Montana Tax Appeal Board, with further review available in the Montana District Court and the Montana Supreme Court. County-level property-tax disputes start at the County Tax Appeal Board under Mont. Code Ann. §15-15-103.

U.S. Tax Court — Montana trial sessions

The United States Tax Court designates Helena as a Montana place of trial, with additional sessions historically held in Billings depending on calendar demand. Sessions use non-permanent courtrooms; the specific address is published with each notice of trial. A petitioner designates the preferred place of trial under Tax Court Rule 140; cases from Missoula, Great Falls, Bozeman, Butte, Kalispell, Havre, and the rest of Montana route to Helena or Billings depending on geography and the Court's calendar.

IRS Taxpayer Assistance Centers

The IRS operates Montana TACs in Billings, Helena, Missoula, and Bozeman. Appointments are scheduled through the IRS office locator or 844-545-5640. The Billings TAC handles the heaviest collection-walk-in volume in eastern Montana; the Missoula TAC services western Montana and the Flathead corridor.

Montana Department of Revenue

The Montana Department of Revenue administers state personal income tax under Mont. Code Ann. Title 15, Chapter 30, the 6.75% flat Corporate Income Tax under Mont. Code Ann. §15-31-121, severance taxes on coal and oil-and-gas production under Title 15, Chapters 35 and 36, ad valorem property-tax oversight under Title 15, Chapter 6, and pass-through entity reporting under Title 15, Chapter 30, Part 33. The Department's main office is in Helena; field offices and Taxpayer Assistance offices operate across the state.

Montana Tax Appeal Board

The Montana Tax Appeal Board (MTAB) is the independent state body that hears appeals from final Department of Revenue assessments and from County Tax Appeal Board property-tax decisions. MTAB has statewide jurisdiction under Mont. Code Ann. Title 15, Chapter 2, Part 2, and its decisions are appealable to the Montana District Court of the county where the taxpayer resides or where the assessment was made, with further review at the Montana Supreme Court. MTAB does not hear federal IRS matters — those go to the U.S. Tax Court.

Resort-tax administration

Montana allows qualifying resort communities and resort areas to impose a local-option tax of up to 3% on lodging, prepared food, and certain retail under Mont. Code Ann. Title 7, Chapter 6, Part 15. Big Sky Resort Area District, the Town of Whitefish, the Town of West Yellowstone, Red Lodge, Cooke City-Silver Gate, Virginia City, St. Regis, and several other communities operate their own collections. There is no state sales tax in Montana, so resort tax is the principal sales-style tax obligation for hospitality operators in those specific markets.

Federal District Court

Montana is a single federal district — the U.S. District Court for the District of Montana — with divisional offices in Billings, Great Falls, Missoula, Helena, and Butte. Refund suits and criminal-tax cases proceed in the relevant division. Major Montana cities served include Billings, Missoula, Great Falls, Bozeman, Butte, Helena, Kalispell, Havre, Anaconda, Belgrade, Whitefish, and Sidney.

Request a free consultation with a Montana tax attorney

A 30-minute call with an attorney costs nothing. Bring your most recent IRS notice, your last filed return, and any state correspondence from the Montana Department of Revenue or a resort-tax district. We will tell you which resolution options actually fit your facts before you sign anything.
