FDIC coverage is not simply one $250,000 bucket per account. It depends on who owns the money, which FDIC-insured institution holds it, and which ownership category applies. This guide explains how the limit works for joint accounts, trust accounts, LLCs, corporations, partnerships, DBAs, and custodial FBO funds, with the failure points that most often change the answer.

In Brief
| Account type | Core FDIC rule | Point that changes the answer |
|---|---|---|
| Single account | $250,000 per depositor at one covered institution for the single-account category.[1] | Accounts with the same owner in the same category are combined. |
| Joint account | Each qualifying co-owner can be insured up to $250,000 for that person’s combined joint-account interests at the same institution.[3] | Co-owners must be natural persons with equal withdrawal rights and proper bank records. |
| Trust account | Up to $250,000 per eligible beneficiary, capped at $1,250,000 per owner when five or more beneficiaries are named.[4] | POD, ITF, formal revocable trust, and many irrevocable trust deposits are combined in one trust category. |
| Business account | A corporation, LLC, partnership, or qualifying association generally gets up to $250,000 in the business category at one institution.[5] | The limit is not multiplied by officers, signers, divisions, or product lines. |
| DBA or sole proprietorship | Usually treated as the owner’s single account, not as a separate business entity.[5] | A trade name does not create a new FDIC depositor. |
| Custodial or FBO account | Pass-through treatment can apply when records show the fiduciary relationship, beneficial owners, balances, and ownership capacity.[2] | Marketing language is not enough; the ledger has to support the claim. |
What is the basic FDIC insurance rule?
The FDIC’s standard maximum deposit insurance amount is $250,000 per depositor, per covered bank, for each account ownership category.[1] Each part has to be true at the same time. The shortcut is useful, but it hides the legal owner, the institution, and the category analysis that drive the result under 12 C.F.R. Part 330.[2]
- Per depositor: the owner of the funds matters. A founder’s personal checking account is not the same depositor as a validly formed corporation, but a sole proprietorship or DBA is usually treated as the owner’s single account category.
- Per bank: deposits at two branches of the same bank are combined. Deposits at separately chartered institutions are separate, even if the banks share a holding company.
- Per ownership category: single accounts, joint accounts, trust accounts, certain retirement accounts, business or organization accounts, employee benefit plan accounts, and government accounts have separate rules.
- Per reliable record: for fiduciary arrangements, the bank and program records need to show the relationship and each owner’s interest.
Coverage math tells you how deposits would be treated if a bank fails. It does not tell you whether a bank is healthy, whether an app is well run, or whether a fintech’s customer ledger reconciles to the bank ledger. Those are separate diligence questions.
How are joint accounts insured?
Joint accounts can provide separate coverage for each co-owner, but only when the account qualifies under the FDIC’s joint-account rules. Each co-owner is insured up to $250,000 for that co-owner’s combined interests in all qualifying joint accounts at the same institution.[3]
Worked example: two spouses have one qualifying joint savings account with $500,000 and no other joint deposits at that bank. If each spouse is treated as owning half, each has a $250,000 joint-account interest, so the full $500,000 can be insured.
The failure point is qualification. A joint account is not just any account with two names on it. The co-owners must be natural persons, they generally need equal withdrawal rights, and the bank’s records must establish the co-ownership. If the same two people also hold another $300,000 joint account at that bank, their interests are combined before the limit is applied: each person is treated as owning $400,000 across joint accounts, with $250,000 insured and $150,000 uninsured.
| Joint account check | Why it matters |
|---|---|
| Are all co-owners natural persons? | A corporation, trust, estate, or partnership cannot qualify as a joint-account co-owner. |
| Do all co-owners have equal withdrawal rights? | If one person can withdraw alone but another cannot, the account may not qualify as joint for FDIC purposes. |
| Do the records support co-ownership? | Coverage follows account records, not informal family intent. |
How are trust accounts insured?
Trust coverage changed on April 1, 2024. The current FDIC rule generally insures an owner’s trust deposits up to $250,000 per eligible beneficiary, capped at $1,250,000 per owner when five or more beneficiaries are named.[4] Informal revocable trusts such as POD and ITF accounts, formal revocable trusts, and many irrevocable trust accounts are now treated together in one trust-account category.
Worked example: a founder has a $900,000 POD savings account and a $500,000 living-trust money market account at the same bank. Both accounts name the same three children as eligible beneficiaries. The combined trust-account balance is $1,400,000, but coverage is 1 owner x 3 beneficiaries x $250,000, or $750,000. The uninsured amount is $650,000 unless the depositor changes banks, changes real ownership and beneficiary facts, or otherwise restructures the deposits in a way that fits the FDIC rules.
The failure point is record quality. For an informal revocable trust, the beneficiaries need to be specifically named in the bank’s deposit account records. For a formal trust, the account title or records must identify the account as a trust account. A casual memo field, stale beneficiary form, or estate-planning document that the bank never recorded is not a coverage plan.
Are LLC and DBA accounts separately insured?
Corporations, partnerships, LLCs, and unincorporated associations can receive business or organization account coverage. The category includes deposit accounts owned by for-profit corporations, nonprofit corporations, Subchapter S corporations, limited liability companies, professional corporations, partnerships, and qualifying associations.[5]
The limit is not multiplied by owners, officers, partners, signers, divisions, cost centers, or product lines. A business account is generally insured up to $250,000 if the entity is engaged in an independent activity, meaning it is operated primarily for a legitimate purpose and not solely to increase deposit insurance coverage.[5]
Worked example: an LLC has $800,000 in its own operating account at one bank. If that account is owned by the LLC and there are no other deposits in the same business category at that bank, $250,000 is insured and $550,000 is uninsured. The fact that the LLC has three members, five officers, or several internal product lines does not create extra business-account limits.
| Entity type | Coverage issue to check |
|---|---|
| Corporation or LLC | Confirm valid formation, exact legal name, and whether separate accounts are owned by the same entity. Multiple divisions of one corporation are combined. |
| Partnership | Partnership deposits belong to the partnership, not to the partners as individuals. Five partners do not create five $250,000 business limits. |
| Unincorporated association | The account title should show the association name. If the account is titled only in officers’ names, it may be treated as personal funds. |
| Sole proprietorship or DBA | Sole proprietorship and DBA accounts are generally insured as the single accounts of the owner, not as separate business-entity accounts. |
The failure point is confusing a trade name with a separate depositor. Maria Lopez DBA ML Consulting may look like a business account on a statement, but if it is a sole proprietorship, the funds are usually added to Maria Lopez’s other single accounts at the same bank.
What about FBO and custodial customer funds?
A company’s operating account and customer funds held in a custodial FBO account are different coverage questions. Under 12 C.F.R. Part 330, pass-through coverage depends on records that disclose the fiduciary relationship and make each beneficial owner’s interest ascertainable from bank records or good-faith records kept in the regular course of business.[2]
The strongest practical example is a fintech program that says customer funds are eligible for FDIC insurance. That claim is incomplete unless the bank and program can prove where the money is, who owns it, which ownership category applies, and whether the customer ledger reconciles to the bank’s records. The FDIC’s 2024 proposed custodial-account requirements focused on the same control point: beneficial-owner records, balances attributable to each owner, ownership category, and reconciliations no less frequently than daily.[6]
The failure point is treating pass-through coverage as automatic. It is a records-based result. If the ledger cannot identify the beneficial owners and their interests, the coverage analysis can fail even if the account title includes FBO language.
Common FDIC insurance mistakes
- Assuming five accounts at one bank create five $250,000 limits. If all five are single accounts owned by the same person at the same bank, they are combined in the single-account category.
- Assuming each branch counts as a separate bank. Deposits held in the same ownership capacity at different branches of the same institution are combined.
- Assuming a DBA creates separate business coverage. A sole proprietor’s trade-name account is generally added to that owner’s single accounts.
- Assuming beneficiaries always multiply coverage without limit. Since April 1, 2024, the trust-account cap is $1,250,000 per owner at one bank when five or more eligible beneficiaries are named.
- Assuming a corporation gets more coverage because several officers can sign. The number of signers or officers does not affect the corporation’s $250,000 business-account limit at one bank.
- Assuming pass-through coverage works without records. For custodial accounts, the analysis needs records that identify beneficial owners and their interests.
- Confusing deposits with investments. Checking accounts, savings accounts, money market deposit accounts, CDs, and official bank items are deposit products; stocks, bonds, mutual funds, annuities, crypto assets, and safe deposit box contents are not FDIC-insured deposits.[1]
How to review FDIC coverage
Use a repeatable workflow before moving material cash, relying on a beneficiary structure, or publishing a coverage claim.
- Confirm the covered institution. Identify the legal bank, not just the branch, app, processor, routing number, or marketing name.
- Build an account inventory by bank. List account title, legal owner, tax owner if relevant, account type, beneficiaries, signers, balance, and whether funds are personal cash, trust cash, entity cash, customer cash, or collateral.
- Assign an FDIC ownership category. Use single, joint, trust, certain retirement, business or organization, employee benefit plan, government, or fiduciary/pass-through treatment as applicable.
- Combine accounts inside the same category. A founder with $300,000 in a personal checking account and $100,000 in a sole-proprietor DBA account at the same bank has $400,000 in the single-account category, with $250,000 insured and $150,000 uninsured.
- Separate entity cash from customer funds. An LLC’s own operating account belongs in the business-account analysis. Customer FBO funds require a separate pass-through review.
- For custodial programs, test the ledger. Require beneficial owner name or identifier, owner balance, ownership category, account mapping, exception reports, and daily reconciliation evidence.
- Run the FDIC’s Electronic Deposit Insurance Estimator, or EDIE, for the account set.[7] EDIE is useful for personal, business, and government accounts, but actual claims are governed by bank records and applicable law.
- Document the date, sources, and assumptions. If the account owner, bank, beneficiary list, FBO records, or FDIC rule changes, redo the calculation.
One bank-level reporting item deserves a narrow endnote. FIL-37-2023 discusses Schedule RC-O Memorandum item 2, estimated uninsured deposits, for banks with $1 billion or more in total assets.[8] That item can help analysts understand a bank’s reported uninsured-deposit exposure, but it does not calculate a specific customer’s coverage. Customer coverage still turns on the owner, accounts, category, institution, and records.
The practical rule is simple enough to use tomorrow: if one legal owner has more than the category limit at one bank, identify the uninsured amount before adding more cash. If the funds are customer or fiduciary funds, do not treat pass-through coverage as real until the records can prove the beneficial owners, balances, and ownership categories.
FAQ
Does adding a beneficiary always increase FDIC coverage?
No. Beneficiaries matter in the trust-account category, but the April 1, 2024 trust rule caps coverage at $1,250,000 per owner at one bank when five or more eligible beneficiaries are named. The beneficiary also has to be eligible and properly reflected in the relevant records.
Can a business open multiple accounts at one bank to multiply coverage?
Not if the same corporation, LLC, partnership, or association owns the accounts. Accounts for different divisions or purposes of the same corporation are aggregated and insured up to $250,000 at one covered institution.
Is a DBA account insured separately from my personal account?
Usually no. A DBA or sole proprietorship is generally insured as the owner’s single account. A separate LLC or corporation can be different, but only if the entity is validly formed, owns the funds, and is engaged in an independent activity.
Are fintech app balances automatically FDIC insured?
No. FDIC insurance protects deposits at an insured bank if that bank fails. For custodial or FBO arrangements, pass-through treatment depends on fiduciary disclosure and records showing each beneficial owner’s interest. A nonbank’s failure is not the same event as a bank failure.
Should analysts use Call Report uninsured-deposit data to answer customer coverage questions?
No. Schedule RC-O uninsured-deposit data is a bank-level reporting item. It helps with bank analysis, but it does not replace customer-by-customer calculations under Part 330 and EDIE.
