If you are the founder, CFO, or controller responsible for moving company cash, this checklist is for the decision before the wire leaves the current bank. It helps you document how much is covered by FDIC insurance, which bank is actually holding the funds, and what records you need if the coverage question ever has to be proven.
Large Deposit Checklist
Before moving a large balance, answer these six questions and save the evidence in the transfer file.
- What is the exact legal bank name and FDIC certificate number?
- Who owns the funds for FDIC purposes: an individual, joint owners, a corporation, a trust, a retirement account, or another owner?
- Which coverage category applies, and do the account records support that category?
- What other balances does the same owner already hold at the same bank in the same category?
- How much is covered under EDIE, and how much remains uninsured before restructuring?
- If an app, sweep, brokered CD, or FBO account is involved, who maintains the owner-by-owner ledger and how often is it reconciled?
If any answer depends on marketing copy instead of bank records, pause before transferring the uninsured portion.
Start With the Basic FDIC Rule
The FDIC’s Your Insured Deposits brochure gives the core rule: the standard maximum deposit insurance amount is $250,000 per depositor, per insured bank, for each ownership category.[1] A coverage memo should turn that sentence into separate tests, because a mistake in any one part can leave cash uninsured.
| FDIC term | What to verify | Common mistake |
|---|---|---|
| $250,000 | Apply the limit to the owner, bank, and category. Include accrued interest. | $300,000 in one single-owner savings account leaves $50,000 over the limit. |
| Depositor | Name the legal owner of the money. | A corporation’s payroll reserve is placed in an officer’s personal account. |
| Bank | Confirm the chartered FDIC institution, not only the app or branch brand. | A fintech app and a direct account use the same partner bank. |
| Category | Use only categories supported by the account records. | Three checking accounts in the same category are treated as one balance. |
| Records | Save the documents that support the calculation. | An FBO account lacks a ledger tying each owner to a balance. |
The FDIC’s Electronic Deposit Insurance Estimator, EDIE, is the practical calculator for this work.[2] Its result is advisory, so keep the EDIE output with account agreements, statements, and the transfer approval.
Trust accounts need extra care. EDIE states that effective April 1, 2024, a trust owner with five or more beneficiaries is not insured beyond $1,250,000 per owner for all trust accounts at the same bank.[2] A sixth beneficiary does not create unlimited coverage.
Confirm the Legal Bank
Brand names are not legal bank names. A digital account, brokered CD, sweep network, prepaid program, embedded-finance account, or sponsor-bank arrangement may involve one or more FDIC institutions behind the customer-facing interface. Use FDIC BankFind Suite to confirm the bank name, certificate number, active status, branch history, and merger history.[3]
The FDIC says the digital official FDIC sign began March 1, 2026 on bank websites, bank applications, and certain bank ATMs.[4] The sign helps identify the bank context, but it does not answer the coverage question by itself. You still need the legal bank, owner, category, balance, and records.
For fintech and sponsor-bank deposits, go one layer deeper. The CFPB’s Synapse action and the FDIC’s proposed custodial-account recordkeeping requirements are a reminder that access and pass-through coverage depend on reliable ledgers, not slogans.[5][6] A useful diligence file names each beneficial owner, the amount attributable to that owner, the category used for coverage, and the reconciliation process.
Sponsor-bank diligence should also include a targeted enforcement check. The Federal Reserve’s 2024 Evolve action addressed deficiencies tied to fintech partnerships, and the interagency third-party risk guidance gives a framework for planning, due diligence, contracts, monitoring, and termination.[7][8] Keep that work focused on whether the deposit records can support the coverage calculation.
- Match the customer-facing brand to the legal bank name in BankFind and in the account agreement.
- Save the FDIC certificate number in the transfer memo.
- For a sweep or brokered placement, list every program bank and the allocation limit for each.
- For a custodial or FBO account, identify who maintains the ledger and how it ties each owner to a balance and category.
- For a bank-fintech arrangement, document the controls that keep customer records current if the intermediary fails.
Map Balances by Category
Large depositors often have several account types at the same institution. Make the map before the wire, not after the monthly statement arrives.
| Account type | Rule to document | Record to keep |
|---|---|---|
| Single account | All single accounts by the same owner at one bank aggregate to $250,000. | Account title, statement, and EDIE report. |
| Joint account | $250,000 per real co-owner with equal withdrawal rights. | Agreement or signature card. |
| Trust account | Owner x eligible beneficiaries x $250,000, subject to the $1,250,000 per-owner cap for five or more beneficiaries. | Trust, POD, or ITF records. |
| Business account | A corporation, partnership, or association gets its own $250,000. A sole proprietorship is treated as single-owner funds. | Formation records, tax ID, account title, and approval. |
| Certain retirement account | $250,000 per owner for qualifying retirement accounts at one bank. | IRA or retirement agreement. |
| Custodial or FBO account | Pass-through coverage depends on records for the actual owner, balance, and category. | Custodial agreement, bank list, ledger, and reconciliations. |
If the decision also depends on bank condition, keep that analysis separate from the insurance calculation. Deep Digital Ventures Banking has a public-data context view for institution research, but the coverage memo should stay centered on ownership, bank identity, category, balance, and records.
Worked Example: $1.2 Million Move
Assume a Delaware C corporation wants to move a $900,000 payroll reserve, and its founder wants to move $300,000 of personal savings. The accounts are direct bank deposits, not a sweep program, and the corporation is legally separate from the founder.
| Choice | Coverage result |
|---|---|
| Put everything at Bank X | $650,000 uninsured for the corporation and $50,000 uninsured for the founder. |
| Split the corporation’s reserve across four separately chartered banks | $250,000 at Bank W, $250,000 at Bank X, $250,000 at Bank Y, and $150,000 at Bank Z can be covered if no other corporate balances sit there. |
| Split the founder’s savings across two banks | $250,000 at Bank X and $50,000 at Bank Y can be covered if the founder has no other single-owner balances there. |
| Save the evidence | Keep EDIE results, BankFind profiles, account agreements, and the officer or board approval. |
The lesson is simple: coverage comes from separate legal owners, separate banks, and supported categories, not from opening more accounts with the same title at the same institution.
Watch for Same-Bank Aggregation
Deposits at separate branches of the same bank are not separately insured. Bank A’s downtown branch and Bank A’s online division may feel different to a customer, but they are the same bank if BankFind shows one legal institution.
Mergers create another aggregation trap. The FDIC’s Merger of IDIs guide explains the six-month rule: deposits from an acquired institution are separately insured from existing deposits at the acquiring institution for an initial six months, while CDs can have different treatment tied to maturity and renewal terms.[9] Calendar the merger date and CD maturity dates before relying on that grace period.
- Check BankFind for name changes, mergers, and acquisitions.
- Ask whether a fintech, brokered CD platform, or sweep network uses a bank where you already hold direct deposits.
- Add payroll, operating, reserve, merchant settlement, trust, escrow, and personal balances at the same bank before calculating coverage.
- For CDs acquired through a merger, compare the maturity date and renewal terms to the FDIC six-month rule.
The failed-bank pages for Silicon Valley Bank, Signature Bank, and First Republic Bank are useful reminders that resolution facts are event-specific.[10][11][12] A systemic risk exception or purchase-and-assumption transaction in one failure is not a planning tool for uninsured cash at the next bank.
Keep Records Clean
Coverage depends on records. A clean file lets the depositor, bank, auditor, board, or reporter explain the result without relying on memory or marketing pages.
- Account titles: use the exact legal entity name for a business account and the exact trust or POD wording for a trust account.
- Beneficiary records: keep the trust, POD, or ITF records that show each distinct beneficiary counted in EDIE.
- Entity authority: keep formation records, tax ID records, and the board or officer approval for business deposits.
- Program disclosures: keep the sweep, brokered, custodial, or placement agreement that names program banks and allocation rules.
- Balance evidence: keep statements showing balances on the transfer date and after the first statement cycle.
- Coverage workpaper: save the EDIE calculation and note assumptions, such as no other balances at the same bank.
For sponsor-bank diligence, save dated enforcement search results from the FDIC, OCC, and Federal Reserve enforcement pages.[13][14][15] If a memo says a bank is under a consent order, cite the agency and order date, not a news recap.
Institution Research Callout
Deep Digital Ventures Banking can help with the institution side of the workflow: start with the bank search and individual bank profiles before wiring cash to a new institution. Use that research alongside, not instead of, the depositor-side coverage file described here.
This checklist is information, not legal or financial advice. For complex trusts, estates, escrow accounts, employee benefit plans, public-unit deposits, customer FBO funds, or balances far above the insurance limit, get written confirmation from the bank and a qualified advisor before moving money. The practical rule is simple: if you cannot identify the bank, owner, category, covered amount, and supporting records, do not move the uninsured portion.
FAQ
Does opening several accounts at the same bank increase FDIC coverage?
Not by itself. Checking, savings, money market, and CD balances held by the same owner in the same category at the same bank are aggregated. Coverage can increase only when a different supported category, different legal owner, or different bank is actually involved.
Does FDIC insurance cover a fintech app failure?
FDIC insurance protects deposits when an FDIC-insured bank fails, up to the applicable limit. It is not general insurance against a nonbank fintech’s bankruptcy, ledger failure, fraud, or outage. For app-based deposits, ask which bank holds the funds and what records show your balance there.
Are sweep programs automatically covered?
No. A sweep program may create coverage across multiple banks only if funds are actually placed at separately chartered institutions and the records show each owner’s balance and category at each bank. Get the program bank list and exclude banks where you already hold deposits.
Should yield ever come before coverage?
No for the uninsured portion of a large deposit. First document the covered amount, the uninsured amount, and the records supporting the result. Then compare yield only among structures that pass the coverage test, or treat the excess as a deliberate credit-risk decision.
