The document packet banks require to open accounts, split by entity type. Newly formed professional entities are a harder onboarding case than a normal LLC, because the bank must verify both the entity and the license behind it. ## For a professional entity (PC / PLLC / PA) | Document | Notes | | ------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------- | | **Filed formation documents**, state-stamped | Articles of incorporation or organization | | **EIN confirmation letter (CP 575)** | The bank matches the legal name against it | | **Bylaws or operating agreement** | Current, signed | | **Organizational consent authorizing accounts** | Naming the authorized signers explicitly | | **Ownership documentation** | Stock certificate, stock ledger, or membership schedule | | **The clinician-owner's professional license** | Current, active | | **Government ID** for every signer and beneficial owner | | | **Certificate of good standing** | Some banks require one, dated recently | | **DBA / assumed name certificate** | If operating under a brand | | **Business address verification** | Lease or utility bill | | **The MSA** | Some banks ask, reasonable, since it explains the relationship between two accounts owned by different people | ## For the MSO | Document | Notes | | --------------------------------------------------- | ---------------------------------------------- | | **Certificate of formation** | State-stamped | | **Operating agreement or bylaws** | Even for a single-member LLC | | **EIN confirmation letter (CP 575)** | | | **Beneficial ownership information** | For owners at or above the bank's threshold | | **Foreign qualification certificate** | For each operating state | | **Government ID** for signers and beneficial owners | | | **Cap table** | For entities with multiple owners or investors | | **Business address verification** | | ## The beneficial ownership problem **Standard beneficial ownership questionnaires do not understand this structure.** The form asks: *"Who owns 25% or more of the entity?"* For the **PC**, the honest answer is **the clinician, 100%**, even though the economics are governed by the MSA and the equity is subject to a transfer restriction. That is the accurate answer, and it is the one to give. For the **MSO**, the answer is your actual cap table. **Answer accurately and be prepared to explain the structure.** Guessing at what the bank wants to hear produces an inaccurate filing. Some banks will follow up; a one-paragraph written explanation of the MSO-PC relationship, prepared in advance, resolves most of it. Also expect questions about **control**: who directs the entity's activities, and who has authority over the accounts. For the PC, the answer is the clinician-officer. If you find yourself wanting to answer "the MSO," that is a signal worth examining in your [CPOM self-audit](/guides/compliance/run-a-cpom-self-audit). ## The per-entity folder template Maintain this for every entity, so entity twelve's onboarding takes an afternoon rather than a week: ```text theme={null} /[Entity Legal Name]/ /01-formation/ articles-filed-stamped.pdf certificate-of-good-standing-[date].pdf foreign-qualifications/ /02-tax/ cp575-ein-letter.pdf w9-current.pdf state-tax-registrations/ /03-governance/ bylaws-or-operating-agreement.pdf organizational-consents.pdf annual-consents/ stock-ledger.pdf stock-certificate-with-legend.pdf /04-licensing/ (PC only) owner-professional-license.pdf license-verification-[date].pdf /05-agreements/ msa-executed.pdf transfer-restriction-executed.pdf baa-executed.pdf /06-banking/ account-details.md signature-cards/ beneficial-ownership-forms/ /07-identifiers/ type2-npi-confirmation.pdf ptan-record.md payer-enrollment-grid.xlsx /08-insurance/ malpractice-coi-current.pdf ``` ## Timing **Budget one to three weeks per entity.** Professional entities frequently trip automated KYB flows, because the system cannot verify a two-week-old PC with a licensed owner and a d/b/a. Expect manual review or a branch visit. **Start this in parallel with NPI and CAQH work**, not after. The account details are a prerequisite for EFT enrollment, which is a prerequisite for getting paid. ## The name must match, everywhere The legal name on the **CP 575** must match: * The bank account * The W-9 * NPPES * Every payer enrollment * The claim's billing provider name One mismatch produces enrollment rejections across every payer, and resolving it means re-filing with each of them. Record the CP 575 name exactly as printed, including punctuation and abbreviations, and use that string everywhere. See [Get NPIs](/guides/enrollment/get-an-npi). ## What to have ready before you apply * [ ] All documents above, current and legible * [ ] The CP 575 legal name recorded exactly as printed * [ ] A one-paragraph written explanation of the MSO-PC structure * [ ] The list of authorized signers, with the PC's officer identified * [ ] Read-only access requirements for bookkeeping * [ ] The naming convention for the accounts * [ ] Confirmation the bank surfaces **ACH addenda data** — you need the TRN to reconcile 835s to deposits ## Related topics - [Step 7: Open bank accounts](/start/zero-to-paid/open-bank-accounts.md) - [Open bank accounts for your MSO and PCs](/guides/banking/open-bank-accounts.md) - [Structure accounts across your entities](/guides/banking/structure-accounts-across-entities.md) - [Why MSO-PC banking is different](/concepts/banking/why-healthcare-banking-is-different.md) - [Per-entity account & access checklist](/reference/banking/per-entity-account-checklist.md)
