Step 6: Open a Business Bank Account

After completing Colorado LLC formation, opening a dedicated business bank account helps separate personal and business finances and protects your limited liability status.

A business bank account also improves credibility with clients, vendors, and payment processors. Most U.S. banks require your LLC to be fully approved before opening an account.

Banks typically require:

• Approved Articles of Organization filed with the Colorado Secretary of State
• Your LLC Operating Agreement
• Employer Identification Number (EIN)
• Valid government-issued photo ID of the owner or authorized manager

Many Colorado LLC owners open their business bank account shortly after receiving their EIN to avoid delays with payments, invoicing, or payroll.

9. Federal Requirements

1. Employer Identification Number (EIN)

Most businesses formed through Colorado LLC formation must obtain an Employer Identification Number (EIN) from the Internal Revenue Service (IRS). The EIN acts as your LLC’s federal tax ID and is required to open a U.S. business bank account, hire employees, work with payment processors, and file federal tax returns.

You can apply for an EIN directly with the IRS: IRS EIN Application . Non-U.S. founders can apply for an EIN without a Social Security Number by submitting Form SS-4. Learn more here: How to Apply for an EIN .

2. Federal Tax Classification

By default, Colorado LLCs are treated as pass-through entities for federal tax purposes. This means the LLC itself does not pay federal income tax. Instead, profits and losses pass through to the owners and are reported on their individual tax returns.

• Single-member LLC: Income is typically reported on Schedule C (Form 1040) .
• Multi-member LLC: Files an informational return using IRS Form 1065 .
• S Corporation election (optional): Eligible Colorado LLCs may elect S-Corp tax treatment by filing IRS Form 2553 to potentially reduce self-employment taxes.

Foreign-owned Colorado LLCs may have additional federal filing obligations, including IRS Form 5472 and IRS Form 1120 , even if the LLC has no U.S. income. Many founders work with a qualified U.S. tax professional to ensure full federal compliance.
