To deposit a large cash gift, take the full amount to your bank branch in person, bring a photo ID and a signed gift letter from the donor, and let the teller handle the paperwork. Any cash deposit over $10,000 triggers an automatic federal currency report, but that report is routine compliance, not an accusation. You almost certainly owe no tax on the gift itself.
What to Bring to the Bank
The most useful thing you can prepare is a gift letter. It’s a short signed statement from the donor covering four points: their full name, their relationship to you, the exact dollar amount, and a clear line saying the money is a gift with no expectation of repayment. Both of you sign and date it.
Federal law doesn’t require a gift letter for the deposit itself, but banks routinely ask for one when a large cash deposit doesn’t match your usual account activity. And if you plan to use the money for a mortgage down payment, you will need one.
Also keep the donor’s address and phone number handy in case the bank wants to verify the source. If the donor can point to where the cash came from, such as a withdrawal from their own savings or the sale of a vehicle, write that down too. Bring a government-issued photo ID for yourself. The teller will count the cash, verify your identity, enter the transaction, and hand you a receipt. Hold onto it until the deposit shows on your statement.
What Happens When the Deposit Exceeds $10,000
Under the Bank Secrecy Act, banks must file a Currency Transaction Report (CTR) any time a customer deposits, withdraws, or exchanges more than $10,000 in physical currency in a single business day.1eCFR. 31 CFR 1010.311 – Filing Obligations for Reports of Transactions in Currency The bank sends the report to the Financial Crimes Enforcement Network (FinCEN) within 15 calendar days.2FFIEC. Assessing Compliance with BSA Regulatory Requirements You won’t get a copy because it isn’t directed at you.
At the counter, the teller will ask for your name, address, date of birth, Social Security number, and the nature of the transaction. “It’s a gift from my parents” is a fine answer. Banks file millions of these reports every year. Answer honestly and you’ll walk out with a normal deposit receipt.
Multiple Deposits Get Added Together
Splitting the trip across branches doesn’t help. If you make several cash deposits at different branches of the same bank on the same day and the combined total exceeds $10,000, the bank aggregates them and files a CTR as if it were one transaction.3Financial Crimes Enforcement Network. Currency Transaction Report Aggregation for Businesses with Common Ownership Their internal systems catch the pattern automatically.
Smaller Deposits Can Still Draw Attention
Federal regulations require banks to file a Suspicious Activity Report (SAR) for any transaction of $5,000 or more that looks designed to dodge the CTR threshold, has no obvious lawful purpose, or resembles money laundering.4eCFR. 12 CFR 208.62 – Suspicious Activity Reports You aren’t notified when one is filed. Which brings us to the single biggest mistake people make with cash gifts.
Never Break the Deposit Into Smaller Pieces
If you receive a $25,000 cash gift and decide to deposit it as three $8,000 chunks over consecutive weeks specifically to stay under the $10,000 threshold, you have committed a federal crime called structuring. It doesn’t matter that the money is a legitimate gift from a parent. The crime is breaking up the deposit to avoid the report, not the source of the cash.
Federal law makes it illegal to structure transactions, or even attempt to structure them, to evade currency reporting. A basic structuring violation carries up to five years in prison, a fine, or both. If the structuring ties to other illegal activity involving more than $100,000 in a 12-month period, the ceiling rises to ten years.5Office of the Law Revision Counsel. 31 USC 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited
The government can also seize the funds through civil asset forfeiture, meaning your account is frozen and the money taken before any conviction. Federal policy has tightened around forfeiture for structuring alone, but the risk is real. Deposit the full amount at once. A CTR is paperwork. A structuring charge is a felony.
Do You Owe Tax on the Gift?
For a domestic cash gift, no. Cash gifts are not income. You don’t report the gift on your federal return, and you don’t owe tax on it, regardless of size. The gift tax is imposed on the donor, not the recipient.6Office of the Law Revision Counsel. 26 USC 2501 – Imposition of Tax
There is one exception recipients need to watch. If you receive more than $100,000 in a calendar year from a nonresident alien or a foreign estate, you must file Form 3520 with the IRS by April 15 of the following year.7Internal Revenue Service. Gifts From Foreign Person The form is informational and creates no tax bill. Filing late is expensive, though: the penalty is 5% of the gift amount per month, capped at 25%.8Internal Revenue Service. Instructions for Form 3520 – Annual Return to Report Transactions with Foreign Trusts and Receipt of Certain Foreign Gifts On a $200,000 foreign gift, that cap works out to $50,000 for doing nothing wrong except filing late.
What the Donor Should Know
Your donor probably doesn’t owe tax either, but the thresholds are worth passing along.
For 2026, a donor can give up to $19,000 per recipient per year without filing anything.9Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 A married couple who splits gifts can move $38,000 to a single person with no filing. The exclusion runs per recipient, so parents could each give $19,000 to their child and their child’s spouse, moving $76,000 in a year with zero paperwork.
When a gift exceeds the annual exclusion, the donor files IRS Form 709 but usually still owes no tax. The excess reduces their lifetime gift and estate tax exemption, which for 2026 sits at $15,000,000 per person after legislation signed in July 2025.10Internal Revenue Service. What’s New – Estate and Gift Tax Form 709 is due April 15 of the year after the gift.11Internal Revenue Service. Instructions for Form 709 A donor who gives you $50,000 in cash would report the $31,000 above the annual exclusion, cutting their remaining lifetime exemption by that much. Tax is only owed if they’ve already used up the full $15 million.
If the Money Is for a Mortgage Down Payment
Mortgage lenders examine every deposit in your bank statements during underwriting, and a large cash deposit is a red flag. Timing and documentation matter more than usual.
Most lenders review at least 60 days of statements. Funds sitting in your account longer than that are typically treated as “seasoned” and won’t need extra explanation. Deposit the cash within the 60-day window, and the lender will want a full trace: a detailed gift letter, proof the donor had the funds (often a copy of their bank statement showing the withdrawal), and confirmation the deposit hit your account.
The gift letter lenders want is more demanding than the one your bank uses. Expect requirements covering the donor’s name, relationship, exact gift amount, the source of the donor’s funds, and an explicit statement that repayment is not expected. Some lenders want both parties to sign in front of a loan officer. Ask your lender early what format they require.
If you have time on your side, deposit the cash gift at least two months before you apply for the mortgage. Once the funds season, most lenders won’t ask about them at all.
