Condo association bank account rules come from several sources at once: state condominium statutes, federal tax law, FDIC coverage limits, the association’s own bylaws, and the lending standards that let owners sell their units. The baseline rules are consistent across most of the country. Keep operating money and reserve money in separate accounts titled to the association, authorize signers through a formal board resolution, don’t commingle association funds with anyone else’s, invest only in safe instruments, pay federal income tax on any interest earned, and give unit owners access to the statements when they ask.
The rest of this article walks through each of those requirements and the practical choices boards face.
Separate Operating and Reserve Accounts
The operating account pays the recurring bills: utilities for common areas, landscaping, insurance, elevator maintenance, management fees. Money moves in and out on a predictable schedule tied to the annual budget.
The reserve account is a different animal. Reserve funds build up over years to pay for infrequent, expensive projects like roof replacement, repaving, or elevator modernization. The two pools should never share an account. When a board dips into reserves to cover an operating shortfall and then the roof fails, the only option left is a special assessment, which is an unplanned lump charge every owner has to pay.
State statutes broadly reinforce this. Transfers between operating and reserve accounts generally require board authorization, and in some states need written approval from at least two directors. Quietly borrowing from reserves without documentation is a fiduciary problem, not a bookkeeping shortcut.
What the Bank Needs to Open the Account
Banks will not open an association account on a handshake. They want proof the association exists as a legal entity and proof that the people walking in actually have authority to act for it. Expect to produce:
- An Employer Identification Number from the IRS. The association cannot open a business account without one, and it is required for any account that earns interest. Associations without an EIN can apply online at IRS.gov and get the number immediately.1Internal Revenue Service. Instructions for Form SS-42Internal Revenue Service. Instructions for Form 1120-H
- Articles of incorporation or association. Some banks will also accept the recorded declaration of condominium.
- The bylaws, so the bank can see which officers hold financial authority.
- A board resolution adopted at a properly noticed meeting, recorded in the minutes, naming the bank and the specific individuals authorized to transact on the account. This is the piece most boards get wrong. Without a signed resolution that matches the meeting minutes, the application usually will not move.
Signature Cards and Keeping Them Current
Each authorized signer typically has to appear at a branch in person with government ID so the bank can keep a signature card on file. The in-person step exists to protect a pool of money that can run into six or seven figures.
The common failure point is turnover. After an election, the association has to update the signature cards promptly, removing the outgoing directors and adding the new ones through the same in-person verification. When nobody follows through, former board members may still be able to withdraw funds. The outgoing treasurer hands over a binder, assumes someone else will handle the bank paperwork, and the gap sits there.
Most states require at least two signatures for withdrawals from reserve accounts, and many bylaws impose a dual-signature rule on operating checks above a set dollar amount. Even when no statute requires it, requiring two signatures on any check over a few thousand dollars is cheap fraud prevention.
FDIC Coverage Is Capped at $250,000 for the Entire Association
This catches boards off guard. FDIC insurance covers deposits at insured banks, but the limit for a condo association is $250,000 total, not $250,000 per unit owner.3Federal Deposit Insurance Corporation. Your Insured Deposits The FDIC treats the association the same way it treats any corporation or unincorporated association: every deposit the entity holds at the same bank is combined and insured up to $250,000.4Federal Deposit Insurance Corporation. Corporation, Partnership and Unincorporated Association Accounts The number of owners or signatories does not change that figure.
For a small association, $250,000 of coverage may be enough. For a larger building with a healthy reserve, the operating and reserve balances combined can easily blow past the limit. Boards in that position typically spread balances across multiple FDIC-insured banks, use a deposit placement service like IntraFi (formerly CDARS) that distributes large balances across a network of banks to keep each within the insurance limit, or hold a portion in U.S. Treasury securities backed by the full faith and credit of the federal government.
Commingling and Investment Limits
State condominium statutes broadly prohibit commingling association funds with anyone else’s money. A director cannot mix assessment revenue with personal finances, and a management company cannot pool the association’s funds with its own corporate accounts or with money belonging to other communities it manages. Every dollar collected from owners has to sit in an account titled in the association’s name. Violating this exposes individual board members to personal liability and generally counts as a breach of fiduciary duty.
Most states also limit how the association can invest its money. The guiding principle is safety of principal, not maximum return. Common permissible investments are FDIC-insured deposit accounts, U.S. government securities, and money market funds invested in government obligations. Reserve money in stocks, speculative real estate, or cryptocurrency would violate the investment standards in virtually every state that addresses the issue. A board member pushing for higher-risk investments is a warning sign.
Reserve Funding and Lender Thresholds
How much belongs in reserves depends on the building’s age and condition, but federal lending rules set a practical floor. The Federal Housing Administration requires associations to allocate at least 10 percent of annual assessments to reserves and capital expenditures as a condition of FHA project approval.5Federal Register. Project Approval for Single-Family Condominiums Fannie Mae and Freddie Mac apply similar benchmarks. A building that fails these thresholds can lose buyers who need FHA-backed or conventional conforming loans, which pulls down values for every owner.
About a dozen states require associations to commission professional reserve studies every three to five years. These studies evaluate the remaining useful life of major components and test whether the current funding plan will cover replacement. Even where state law is silent, lenders and insurance carriers increasingly expect one.
Federal Tax on Interest Income
Every condo association that earns interest on its accounts owes federal income tax on that interest. Monthly assessments are treated as exempt function income and are not taxed.6Office of the Law Revision Counsel. 26 USC 528 – Certain Homeowners Associations Interest earned on operating or reserve balances, along with other non-exempt income like clubhouse rental fees, is taxable.
Most associations file IRS Form 1120-H, which applies a flat 30 percent tax rate to non-exempt taxable income after a $100 deduction.6Office of the Law Revision Counsel. 26 USC 528 – Certain Homeowners Associations For calendar-year associations, the return is due April 15. An automatic extension is available by filing Form 7004 before the original deadline.2Internal Revenue Service. Instructions for Form 1120-H Missing the deadline triggers a failure-to-file penalty of 5 percent of the unpaid tax for each month the return is late, up to 25 percent.7Internal Revenue Service. Failure to File Penalty Boards that assume the association doesn’t have to file because it’s “nonprofit” are making a common and expensive mistake. The IRS treats condo associations as taxable entities that must file every year.
Owner Access to the Bank Records
Unit owners have a legal right to see how their assessment dollars are managed. State statutes generally classify bank statements, account reconciliations, and financial reports as part of the association’s official records, which owners can inspect on request.
Procedure varies by state. Most require a written request, sometimes by certified mail, and give the association a set window, commonly 5 to 15 business days, to make the records available or produce copies. Some states impose daily penalties for ignored or delayed requests, and courts may award the requesting owner’s attorney fees if the matter goes to litigation.
Boards can redact sensitive information before releasing records. Account numbers, routing numbers, and Social Security numbers of individual owners should be blacked out to prevent identity theft. Balances and transaction history, though, are not something the board can withhold. An owner asking to see the statements is exercising a statutory right.
When an Outside Audit Is Required
Many states require associations to have their finances independently reviewed or audited at regular intervals, and the requirements scale with size. Smaller associations may only need an annual financial report prepared by the treasurer. Larger ones, usually those above a revenue threshold, have to hire a CPA for a formal review or full audit. The thresholds that trigger a mandatory audit vary widely by state, roughly $75,000 to $500,000 in annual income.
Even where state law doesn’t require it, the association’s own governing documents may. Check the bylaws and declaration before assuming a treasurer-prepared report is enough. Skipping a required audit exposes the board to liability and erodes owner confidence. A building where the same treasurer has handled the books for a decade with no outside review has a governance problem that tends to become a financial one.
