There is no federal law that caps how much money you can have in the bank. You can hold any amount across checking, savings, money market, and CD accounts without hitting a legal ceiling. What the law does regulate is how large deposits get reported, how much of your balance the government will insure if the bank fails, how interest is taxed, and how your balance is counted if you receive means-tested benefits or face a creditor. Those rules create practical thresholds worth knowing before your balance gets big.
Cash Deposits Over $10,000
Deposit more than $10,000 in cash on a single day and your bank files a Currency Transaction Report with the Financial Crimes Enforcement Network. The report covers physical currency only, not checks, wires, or electronic transfers. It includes your name, Social Security number, and the transaction details. The filing does not block your deposit and does not create any penalty on its own; it is a record federal regulators can review for signs of money laundering.1FinCEN.gov. Notice to Customers: A CTR Reference Guide
Trying to dodge that threshold is where people get into serious trouble. Breaking a $15,000 cash deposit into three $5,000 pieces across consecutive days, or across different branches of the same bank, is called “structuring,” and it is a federal crime regardless of whether the underlying money is legitimate.2Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited
A structuring conviction carries up to five years in prison and fines, rising to ten years when the structuring is part of a broader pattern of illegal activity exceeding $100,000 in a twelve-month period. The government can also seize the funds through civil forfeiture, sometimes before any criminal charge is filed. Banks run automated software that flags patterns of deposits sitting just under $10,000, so this is far easier to detect than most people assume.2Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited
How Much of Your Balance Is Insured
There is no cap on deposits, but there is a cap on what the government will replace if your bank fails. The Federal Deposit Insurance Corporation insures deposits at member banks up to $250,000 per depositor, per institution, per ownership category. The National Credit Union Administration provides the same $250,000 limit at federally insured credit unions.3FDIC.gov. Deposit Insurance FAQs
The “per ownership category” part lets coverage expand well past $250,000 at the same bank. Individual accounts and joint accounts are insured separately. If you hold $250,000 in a savings account in your name alone and $500,000 in a joint account with your spouse, your coverage comes to $500,000: $250,000 for the individual account plus $250,000 for your half of the joint account. Your spouse’s half gets its own $250,000.4eCFR. 12 CFR Part 330 – Deposit Insurance Coverage
Revocable trust accounts push the ceiling higher still. Coverage is calculated at $250,000 per named beneficiary, up to a maximum of $1,250,000 per trust owner at one bank when five or more beneficiaries are listed.5FDIC.gov. Trust Accounts
Because the limit applies per institution, the simplest way to fully protect a large balance is to spread it across multiple FDIC-insured banks. Someone with $750,000 could hold $250,000 at three separate banks and every dollar would be insured. Deposit placement services automate this by splitting your funds across a network of partner banks so you deal with one account while staying under the cap at each.
Taxes as Your Balance Grows
A large bank balance does not trigger a special tax, but the interest it earns is taxable income. Your bank must send you and the IRS a Form 1099-INT for any account that earns at least $10 in interest during the year.6Internal Revenue Service. About Form 1099-INT, Interest Income
You owe federal income tax on that interest whether or not you receive a 1099-INT. Eight dollars of interest generates no form, but the income is still reportable. With savings accounts and CDs paying meaningful rates again, a six-figure balance in a high-yield account can easily owe hundreds or thousands in taxes on interest alone, a cost that catches people off guard when they treat savings as tax-free.
Banks are also required to apply backup withholding at 24% on interest payments if you have not provided a correct taxpayer identification number, or if the IRS has notified the bank that you previously underreported interest income.7Internal Revenue Service. Backup Withholding
Limits That Apply If You Receive Government Benefits
The real “bank account limit” affecting millions of Americans is the resource cap tied to means-tested benefit programs. If you receive Supplemental Security Income, Medicaid for long-term care, or SNAP, your bank balance can directly determine whether you stay eligible.
Supplemental Security Income
SSI has the strictest asset test of any major federal program. As of 2026, an individual cannot hold more than $2,000 in countable resources, and a married couple cannot exceed $3,000.8Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Countable resources include cash, bank balances, stocks, and bonds.9Social Security Administration. SSI Spotlight on Resources
If your balance pushes your total countable resources even a dollar over the limit at any point during a month, you lose SSI eligibility for that month. The Social Security Administration reviews resources regularly, and going over results in an overpayment notice requiring you to repay benefits received while over the limit.10Social Security Administration. Understanding Supplemental Security Income Overpayments Some assets do not count: your home, one vehicle used for transportation, household goods, and burial plots are excluded.9Social Security Administration. SSI Spotlight on Resources
Medicaid
Medicaid rules vary significantly by state and by the type of coverage. For adults who qualify under the Affordable Care Act’s Medicaid expansion, most states do not impose an asset test; eligibility is based on income alone. For elderly or disabled individuals seeking long-term care coverage, the majority of states still apply asset limits, often around $2,000 for an individual. Only a handful of states have eliminated the asset test for this population. If you are planning for long-term care costs, check your state’s specific rules.
SNAP
Federal SNAP asset limits for fiscal year 2026 are $3,000 for most households and $4,500 for households that include someone age 60 or older or a member with a disability.11USDA Food and Nutrition Service. SNAP FY 2026 Cost-of-Living Adjustments In practice, most states use broad-based categorical eligibility, which effectively waives the asset test for the majority of SNAP applicants. Whether your bank balance matters depends on your state’s approach.
Saving More Without Losing SSI
SSI’s resource limits are punishingly low, but a few legal tools let you set money aside that does not count against them.
If you became disabled before age 26, you can open an ABLE (Achieving a Better Life Experience) account. The first $100,000 is completely excluded from SSI’s resource calculation. If the ABLE balance exceeds $100,000, only the excess is counted, and SSI payments are suspended rather than permanently terminated, so they resume once you spend down below the threshold.12Social Security Administration. Spotlight on Achieving a Better Life Experience (ABLE) Accounts
Total annual contributions from all sources are capped at the gift tax exclusion amount, which is $19,000 for 2026. Employed account holders who do not participate in an employer retirement plan can contribute additional funds above that cap, up to the lesser of the federal poverty level for a one-person household or their annual compensation.12Social Security Administration. Spotlight on Achieving a Better Life Experience (ABLE) Accounts
You can also set aside up to $1,500 specifically for your burial expenses, and the same amount for a spouse, without it counting toward SSI’s resource limit. The money must sit in a separate account clearly designated for burial costs. This exclusion is reduced by the face value of any life insurance policies whose cash surrender value is already excluded from your resources.13eCFR. 20 CFR 416.1231 – Burial Spaces and Certain Funds Set Aside for Burial Expenses
What does not work is giving money to relatives shortly before applying. For Medicaid long-term care, the look-back period is 60 months. The state reviews every asset transfer you made during those five years, and transfers for less than fair market value trigger a penalty period during which you are ineligible for coverage of nursing home or long-term care costs. The penalty length depends on the value transferred.14Centers for Medicare and Medicaid Services. Transfer of Assets in the Medicaid Program – Important Facts for State Policymakers SSI uses a shorter look-back: giving away a resource or selling it for less than its value can disqualify you from SSI for up to 36 months, depending on the amount.15Social Security Administration. SSI Spotlight on Transfers of Resources
If Any of the Money Is Held Overseas
Accounts held outside the United States carry two separate federal reporting requirements, and missing either carries severe penalties. The FBAR (Report of Foreign Bank and Financial Accounts) requires FinCEN Form 114 if the combined value of all your foreign financial accounts exceeds $10,000 at any point during the year, whether or not the accounts earn income.16Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) Civil penalties range from roughly $16,500 per report for non-willful violations to the greater of approximately $165,000 or 50% of the account balance for willful violations, adjusted annually for inflation.
FATCA reporting on IRS Form 8938 has higher thresholds that depend on filing status. Single filers living in the U.S. must report foreign financial assets worth more than $50,000 on the last day of the tax year or more than $75,000 at any point during the year. For married couples filing jointly, those thresholds double to $100,000 and $150,000.17Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets The two reports serve different agencies, and filing one does not satisfy the other.
What a Creditor Can Reach
When a creditor wins a court judgment against you, a bank account garnishment is one of the most common collection tools: a court order telling your bank to freeze and turn over funds. Federal law protects certain types of money in the account from seizure.
When your bank receives a garnishment order, it must first review the account for direct deposits of protected federal benefits, including Social Security, SSI, veterans’ benefits, federal employee retirement payments, and railroad retirement benefits. The bank calculates a “protected amount” by adding up all qualifying federal benefit deposits from the two months before the garnishment arrived. If your account holds $3,500 in Social Security deposits from that period, the bank must keep that $3,500 accessible to you regardless of the garnishment. The protection applies even when benefit money is mixed with wages or other income in the same account.18eCFR. 31 CFR Part 212 – Garnishment of Accounts Containing Federal Benefit Payments
Beyond the federal benefit protection, most states provide additional exemptions for bank account funds. These “wildcard” exemptions protect a fixed dollar amount of cash or liquid assets from creditors, and the protected amount varies widely by state. Some states shield only a few hundred dollars; others protect several thousand. If you are facing a garnishment, your state’s exemption laws determine how much of your non-benefit funds a creditor can actually reach.
