How to Get a Montana Tax Clearance Certificate

A Montana tax clearance certificate is a free document from the Montana Department of Revenue confirming that a business has filed every required return and paid every tax, penalty, and interest amount owed to the state. You request it through the department’s TransAction Portal at tap.dor.mt.gov using Form CR-T, and the department aims to process requests within 30 days.¹ Once issued, the certificate is valid for six months.²

When You Actually Need One

Not every business exit requires this document. The Department of Revenue says a straightforward voluntary dissolution or withdrawal filed with the Secretary of State generally does not need a tax clearance certificate.¹ The certificate becomes mandatory when the state needs proof that a departing or delinquent entity has settled its tax obligations before regaining or giving up legal status.

The common triggers:

Reinstatement of an LLC administratively dissolved by the Secretary of State for missed annual reports, no registered agent, or unpaid fees. You have five years from the dissolution date to apply, and the certificate must accompany the reinstatement application.³
Reinstatement of a dissolved corporation, which requires a Department of Revenue certificate confirming all taxes under Title 15 have been paid, plus any missing annual reports and a filing fee.⁴
Withdrawal of a foreign corporation from Montana. The certificate must be attached to the withdrawal statement, and the statute expressly says it does not release the corporation from liability for taxes, penalties, or interest later discovered.⁵
Withdrawal of a foreign LLC, which cannot leave Montana until it obtains a certificate of withdrawal from the Secretary of State; the Department of Revenue may require a tax certificate as part of that process.⁶
Reviving a corporation whose powers were suspended or forfeited for a missed return or unpaid tax. The certificate must show the delinquent return was filed and all taxes, interest, and penalties were paid. Applying more than a year after the suspension doubles the tax and penalties owed.⁷
Liquor license applications, where the applicant must be current on all tax filings, taxes, interest, and penalties owed to Montana.⁸

When in doubt, request the certificate anyway. There is no cost, and having it in hand avoids delays if the Secretary of State asks for it.

Tax Certificate vs. Tax Clearance Certificate

Montana actually issues two related documents through the same process, and the difference catches people out.

A standard tax certificate (sometimes called a dissolution or withdrawal certificate) confirms that the entity has filed all applicable returns and paid all taxes owed through the date of the request. It is the version used when a voluntary dissolution or withdrawal is still in progress.⁹

A tax clearance certificate is the final version. It confirms that all returns have been filed and all taxes have been paid through the entity’s last year of existence in Montana.⁹ To get this version, you must file a final return marked “Final Return” covering the short period from your last filed return through the date of dissolution or cessation of business.¹⁰ Receiving the standard certificate during a voluntary dissolution does not excuse you from filing that final return.²

One more wrinkle. If your entity is a subsidiary in a combined group, the Department of Revenue cannot issue a tax clearance certificate until a final return is filed for the whole combined group.¹ That trips up people trying to wind down a single entity inside a larger corporate structure.

How to Request It: Form CR-T

You file Form CR-T through the TransAction Portal at tap.dor.mt.gov. You do not need to create a TAP account to submit the form.² If you would rather use paper, you can request the form by mail or by calling the Department of Revenue at (406) 444-6900.

Your request will not be processed unless it includes the entity’s name, mailing address, and Federal Employer Identification Number. A single-member LLC without employees and without a FEIN uses the owner’s Social Security number instead.¹¹ You will also need your Secretary of State filing number exactly as it appears in your registration.¹

Before filing, submit any missing returns and pay every outstanding balance. The department will deny requests with unfiled returns or unpaid tax.² For reinstatement in particular, the department issues the certificate only after all Title 15 taxes, interest, and penalties are paid in full.¹¹

Single-Member LLCs

If your business is a single-member LLC that has not elected corporate tax treatment, the department treats the LLC and the owner as the same employer for withholding purposes. No certificate will be issued unless withholding taxes have been paid by both the LLC and the owner.¹¹ Unpaid withholding on your personal account will block the LLC’s certificate.

Using an Accountant or Attorney

The Department of Revenue will not discuss your tax information with a representative unless you have authorized it. File Form POA (Power of Attorney and Declaration of Representative) with the department, or submit Federal Form 2848 as long as it specifically lists Montana, the tax type, the form number, and the applicable years. You can also grant access through TAP directly.¹²

Processing Time, Cost, and Expiration

There is no fee, and the department’s stated goal is to issue the certificate within 30 days.¹ There is no expedited option, so build the wait into your timeline.

The certificate expires six months after it is issued.² If you miss that window with the Secretary of State, you have to request a new one and wait through processing again. With a 30-day processing target and six-month shelf life, the practical window is tighter than it looks once you factor in coordinating other filings.

Filing It With the Secretary of State

When the Secretary of State requires the certificate for your filing, you upload it electronically through the state’s business portal at biz.sosmt.gov.² The Secretary of State directs businesses that need a certificate to request it through TAP before proceeding with the dissolution, withdrawal, or termination filing.¹³

For a foreign corporation, the certificate is a statutory condition of withdrawal and must be attached to the withdrawal statement itself.⁵ For LLCs and corporations reinstating after administrative dissolution, it is submitted with the reinstatement application and any outstanding annual reports.³

Mergers and C Corporation Conversions

A C corporation merging with or consolidating into another entity has an extra requirement. Along with the Form CR-T request, the Department of Revenue requires an Assumption of Montana Tax Liability (Form ATL), which identifies the entity taking on the surviving tax obligations.¹ Without Form ATL, the department will not process the certificate. This applies whether the surviving entity is a Montana company or a foreign corporation absorbing a Montana entity.

If You Are Buying a Business, Not Winding One Down

The certificate is also a due diligence tool. Under Montana’s sales and use tax provisions, when a business owner sells or otherwise disposes of the business or its stock of goods, all taxes owed become due immediately and the seller must file a return and pay within 10 days. As buyer, you are liable for the full amount of any unpaid tax unless you withhold enough from the purchase price to cover it, or the seller gives you a receipt from the department showing full payment.¹⁴

There is one escape valve. If you give the department written notice of the acquisition and it does not issue an assessment against the former owner within six months, you are no longer on the hook for the seller’s tax debt. Requesting a tax clearance certificate from the Department of Revenue as part of your due diligence is one of the simplest ways to confirm the seller’s tax status before closing.
