What Information Do You Need to Register?

Gathering all required information in advance is important before you begin applying for a Montana sales tax permit. The Montana Department of Revenue will ask for various business and personal details to verify your identity, classify your business activity, and determine your tax obligations, including sales tax remittance requirements.

Here’s what you’ll need:

Business Information

This information helps the state identify your business and understand its legal setup. Accurate addresses ensure you receive important mail and notices related to your tax obligations. You’ll need to provide basic business details, including:

  • Legal business name
  • Trade name or DBA (if applicable)
  • Business structure (LLC, corporation, sole proprietorship, etc.)
  • Physical and mailing addresses
  • Start date of business operations in Montana
  • Addresses for multiple locations (if applicable)

Federal EIN (Employer Identification Number)

Your EIN is issued by the IRS and used to identify your business for federal tax purposes. This is required for most business entities (except sole proprietors without employees). The EIN connects your state tax filings with your federal tax records, ensuring consistency and proper identification of your business.

North American Industry Classification System (NAICS) Code

This code helps Montana classify your business activities for tax purposes and may affect what taxes you owe or exemptions you qualify for. Selecting the correct NAICS code ensures your business is correctly identified in state records.

It also helps determine eligibility for specific tax credits or incentives and can influence how your sales or use tax obligations are assessed. If you’re unsure which code best fits your business, resources like naics.com offer detailed descriptions to guide you.

Responsible Party Information

The responsible party is legally accountable for the business’s tax filings and communications with the Montana Department of Revenue. The state requires information on at least one responsible party, typically an owner, officer, or manager. You’ll need:

  • Full legal name
  • Social Security Number (SSN) or EIN (for entities)
  • Title/role in the business
  • Contact information

Contact Details

Accurate contact details help you stay compliant by ensuring you don’t miss important updates, deadlines, or requests from the state. Ensure you have the phone number and email address you’ll use to receive official notices from the Montana Department of Revenue.

Additional Documentation (If Applicable)

These documents verify your business’s legal structure and may be required to complete registration or comply with other tax obligations beyond sales tax. Depending on your business type, you might also need:

  • Articles of incorporation or partnership agreements (for corporations/partnerships)
  • Payroll tax registration info if hiring employees

Having all this information ready before you start will make your Montana sales tax permit registration faster and help avoid unnecessary delays. If you’re unsure about your specific situation, checking with the Montana Department of Revenue is always a good idea.

How Much Does It Cost to Register for a Sales Tax Permit in Montana?
