APA TREAS 310 on your bank statement is a direct deposit from the U.S. Treasury sent through the Automated Clearing House network. The “TREAS” portion names the Treasury as the source, and “310” is the Treasury’s classification for non-payroll electronic deposits, which covers tax refunds, federal benefit payments, and other disbursements. The “APA” prefix is a general routing designation that appears when the deposit does not carry a more specific agency tag. To find out which agency actually sent the money and why, look at the descriptive text next to the code and match it to the amount and date.
What the Code Is Telling You
Nearly all federal payments flow through Treasury, no matter which agency authorized them. The 310 number separates these payments from federal payroll, which uses a different classification. A federal employee’s paycheck would not show 310.
The prefix narrows the source. “IRS TREAS 310” means the IRS initiated the payment. “SSA TREAS 310” points to Social Security. “APA TREAS 310” is more generic and shows up when the deposit does not carry one of those specific agency prefixes. Whatever the prefix, every TREAS 310 entry is a legitimate federal electronic payment.
Which Federal Payment You Likely Received
The most common TREAS 310 deposit is an IRS tax refund. When a refund arrives, the entry typically reads “IRS TREAS 310” with descriptive text of “TAX REF.”1Taxpayer Advocate Service.

If you filed a return in the last few months and the amount matches what you expected, that is almost certainly the explanation.
Social Security retirement, disability, and survivor benefits also come through as TREAS 310 deposits. Veterans Affairs payments for disability compensation, pension, or education benefits use the same code, often with descriptive text like “VAED” for Veterans Affairs Education. Railroad Retirement Board and Office of Personnel Management payments follow the same pattern.
In recent years the code also carried Economic Impact Payments and advance Child Tax Credit payments, which showed descriptive text of “TAXEIP3” and “CHILDCTC” respectively.1Taxpayer Advocate Service. TAS Tax Tip: Got a Direct Deposit From the IRS, But Not Sure What It Is For? Those programs have ended, but older statements may still display those labels. Descriptive text of “MISC PAY” indicates a miscellaneous disbursement that does not fit a standard category and usually takes more digging to identify.
How To Identify Your Specific Deposit
Start with the descriptive text next to TREAS 310. Your bank may display it differently depending on where you look, so check both the mobile app and the desktop site if one truncates the entry. “TAX REF” means a tax refund. “SSA” means Social Security. “VAED” or “VACP” points to Veterans Affairs. Write down the exact amount, the deposit date, and the full text.
If the descriptive text points to a tax refund, the IRS “Where’s My Refund?” tool will confirm it. You need your Social Security number, filing status, and the exact whole-dollar refund amount you expected. The tool becomes available 24 hours after you e-file a current-year return, three to four days after e-filing a prior-year return, or four weeks after mailing a paper return.2Internal Revenue Service.

For Social Security, compare the deposit date against the published payment schedule. Benefits are scheduled by birth date, with Wednesdays in each month assigned to different ranges of birthdays.3Social Security Administration. Schedule of Social Security Benefit Payments 2026-2027 If the date and the amount line up with your expected benefit, you have your answer.
When nothing on the statement points clearly to an agency, call the Bureau of the Fiscal Service at 855-868-0151. They can identify which federal entity authorized the deposit and direct you to the right office for any follow-up.4USAGov. Government Checks and Payments Have the deposit date, the exact dollar amount, and the full transaction description ready.
If the Code Reads TREAS 449 Instead
“TREAS 449” is a different signal. The 449 code means the Treasury Offset Program intercepted part or all of a federal payment to cover a delinquent debt such as unpaid child support, defaulted student loans, or overdue taxes. The program matches federal payments against databases of past-due obligations, and when there is a match the government withholds the money before it reaches you.5Bureau of the Fiscal Service. Treasury Offset Program
If a refund or benefit arrived smaller than expected and the code is 449 rather than 310, the shortfall is not a bank error. Call 800-304-3107 and select option 1 to find out whether your payment was offset and which debt caused it.6Bureau of the Fiscal Service. Contact Us
If You Weren’t Expecting the Money
An unexpected TREAS 310 deposit is not always good news. In one common scheme, criminals steal personal information, file a fraudulent tax return, and have the refund sent to the victim’s own bank account. A scammer then contacts the victim posing as the IRS or a collection agency, demands the money be forwarded, and threatens arrest or penalties. The IRS does not call and demand immediate payment over the phone, so any such contact is a scam.
If you receive a refund you did not expect and did not file a return that would generate it, you need to return it. Contact the ACH department at your bank and ask them to return the deposit to the IRS. Then call the IRS at 800-829-1040 for individuals or 800-829-4933 for businesses to explain what happened.7Internal Revenue Service. Topic No. 161, Returning an Erroneous Refund – Paper Check or Direct Deposit Do not ignore the deposit. The IRS treats erroneous refunds as a debt, and interest can accrue from the date the refund was issued.
If your bank cannot reverse the direct deposit, send a personal check or money order to the IRS instead. Write “Payment of erroneous direct deposit” on the check, include the tax period if you know it, and note your Social Security number. The IRS expects repayment within 21 days of its demand notice.8Internal Revenue Service. 21.4.5 Erroneous Refunds
If an Expected Payment Is Missing
When a payment you expected never shows up, or the amount is wrong and the code is 310 rather than 449, go to the agency that should have sent it. For tax refunds, use “Where’s My Refund?” or call the IRS. For Social Security discrepancies, contact the Social Security Administration. For VA payments, reach the Department of Veterans Affairs.
The formal investigation for a missing electronic payment is called a payment trace. Direct deposit traces can take several weeks because financial institutions control much of the process.6Bureau of the Fiscal Service.
