What documents do I need to open a business checking account?

You need the EIN confirmation letter from the IRS, articles of incorporation (for corporations) or articles of organization (for LLCs), the operating agreement or bylaws, government-issued photo ID for each beneficial owner holding 25% or more, and documentation of your principal business address. Sole proprietors provide DBA filing and SSN in place of EIN if no EIN exists. Nonprofits add 501(c)(3) determination letter.

How do I choose the right checking tier?

Analysis Checking suits high-activity businesses with many transactions per month — the earnings credit offsets service fees. Business Interest Checking suits companies that maintain steady balances and want interest while retaining transaction activity. Commercial Checking is the default for mid-market and enterprise with custom service bundles and negotiated pricing. Your relationship manager models the three tiers against your expected volumes and recommends the optimal fit.

How do I fund a new business checking account?

Fund a new account by ACH transfer from an existing business account, incoming wire from another bank, or check deposit at opening. Minimum opening deposits vary by tier — Analysis Checking typically opens with a nominal amount; Commercial Checking tiers with negotiated minimums. Deposits post upon receipt subject to standard funds-availability policy.

How long does account opening take?

Simple single-entity account opening typically completes in 1-3 business days once documentation is submitted. Multi-entity or complex ownership structures with beneficial ownership review can take 5-10 business days. Enterprise onboarding with treasury services, positive pay, and multi-user setup extends to 10-20 business days. Your relationship manager provides a timeline during the scoping call.

What happens after my account opens?

Your administrator receives provisioning credentials by courier. The admin creates online banking users, assigns roles, sets approval thresholds, configures MFA policy, and distributes activation links. Each user registers MFA methods in 10-15 minutes and accesses the business portal. Relationship manager scheduling calls follow within two weeks to review portal usage and scope additional treasury services.

Western Alliance Bank Business Checking Account — Open Online Walkthrough

Western Alliance Bank business checking accounts anchor your commercial banking relationship. This page walks through opening a business checking account — picking the right tier for your activity pattern, gathering the documentation Customer Identification Program (CIP) rules require, submitting the application, funding, and activating the business portal. Simple single-entity account openings typically close in 1-3 business days; multi-entity and enterprise structures take longer.

The three primary tiers — Analysis Checking, Business Interest Checking, and Commercial Checking — solve different problems. Analysis pays no interest but uses an earnings credit on balances to offset per-item service fees, so active businesses net lower total cost. Business Interest pays interest on balances for companies that hold steady cash. Commercial Checking is the customizable mid-market and enterprise tier with negotiated pricing. Your relationship manager models the three against your expected volumes during scoping.
