Open a Business Bank Account for Your Oregon LLC

A dedicated business bank account is essential for maintaining your LLC's liability protection. Commingling personal and business funds is one of the fastest ways to compromise the "corporate veil" — the legal separation between you and your LLC that protects personal assets. After forming your Oregon LLC and obtaining your EIN, opening a business account should be your next step. For all post-formation tasks, see our compliance overview.

Why a Separate Account Matters in Oregon

Oregon courts can "pierce the LLC veil" if they determine the LLC is merely an alter ego of the owner. Key factors Oregon courts examine (based on ORS Chapter 63 and case law):

• Commingling of funds — Using personal accounts for business transactions, or vice versa
• Undercapitalization — Operating without adequate business funds
• Failure to observe formalities — Not maintaining separate records, no operating agreement
• Use of LLC funds for personal expenses — Treating the business account like a personal account

A separate business bank account with clear transactions is your strongest evidence that the LLC is a legitimate, separate entity.

Tips for Oregon LLC Owners

1. Open the account immediately after formation — Don't conduct business through personal accounts even temporarily
2. Deposit formation costs as a capital contribution — Document the initial funding of your LLC clearly
3. Never pay personal expenses from the business account — Take formal distributions (owner draws) and move funds to personal before spending
4. Keep enough balance to avoid monthly fees — Most Oregon bank business accounts waive monthly fees above $1,500-$5,000 balance
5. Consider a separate savings/reserve account — Set aside estimated tax payments (30-40% of income) in a separate sub-account so you're never surprised at quarterly tax time
6. Get a business debit card — For everyday business expenses, keeping a clear paper trail

FAQ

Can I use my personal bank account for my Oregon LLC?

Technically yes in the short term, but it's strongly discouraged. Commingling personal and business funds weakens your LLC's liability protection and makes bookkeeping and tax filing significantly more complex. Oregon courts consider commingling when deciding whether to pierce the LLC veil.

Do I need to wait for the EIN letter in the mail?

No. The online confirmation number from the IRS EIN application works immediately at most Oregon banks. The formal CP 575 letter arrives 4-6 weeks later, but you don't need to wait for it.

Can a single-member LLC use a simpler account?

Yes. Many Oregon banks and credit unions offer "sole proprietor" or "freelancer" business accounts with lower minimums and fewer fees. As long as it's in your LLC's legal name with the LLC's EIN, it satisfies the separation requirement.

What about business credit cards?

Apply after establishing the bank account. Business credit cards help build business credit separate from personal credit. Many Oregon LLC owners start with a secured business credit card and graduate to unsecured options after 6-12 months of account history.
