The 310 code means your refund is being sent by direct deposit to a bank account
When you see 310 on your IRS tax transcript or refund status page, it indicates the delivery method for your refund. Code 310 specifically means the IRS will deposit your money directly into a bank account you provided on your tax return — not mail a check, not load it onto a card, but transfer it electronically to the financial institution you named.
The IRS uses these numeric codes to track how refunds move through their system. If you chose direct deposit when you filed your return, you should see 310 appear on your transcript once the IRS has processed your return and approved the refund amount. It is not a problem code or a delay marker — it is simply the IRS labeling the method they will use to send your money back.
Key Takeaways
- Code 310 means your refund will arrive by direct deposit to the bank account listed on your tax return, not by check or prepaid card.
- You will see 310 on your IRS transcript or when you check your refund status through Where's My Refund, and it appears after the IRS has processed and approved your return.
- Direct deposit refunds typically arrive within one to three business days after the IRS releases the funds, though the exact timing depends on your bank's processing speed.
- If you see 310 but your refund has not arrived after five business days, contact your bank first to confirm the deposit was received on their end.
Where you will see the 310 code
The 310 code appears in two main places. First, on your IRS tax transcript — the official record of your tax filing and refund status. You can view your transcript by logging into your IRS account at irs.gov or by calling the IRS at 1-800-829-1040 and requesting it over the phone. The code will show up in the "Refund Status" or "Refund Method" section of the transcript.
Second, you may see it when you use the Where's My Refund tool on irs.gov. This tool shows you the current status of your refund in real time. Once your return is processed and approved, the tool will display your expected refund amount and the delivery method — code 310 means direct deposit. The tool updates once per day, usually overnight, so check it in the morning for the most current information.
You will not see 310 on your actual tax return form (the 1040 or other form you filed). It only appears in the IRS's internal tracking systems and on the documents they generate after processing your return.
How long direct deposit refunds take to arrive
Once the IRS releases your refund with a 310 code, the money typically arrives in your bank account within one to three business days. This is the standard timeframe for electronic transfers between the IRS's bank and your financial institution. The IRS does not control the exact moment the money lands in your account — that depends partly on your bank's processing schedule.
The total time from filing to receiving your refund is longer. The IRS usually takes 21 calendar days to process a return and approve the refund, though many returns process faster. Once approved and marked with code 310, the one- to three-day deposit window begins. If you filed early in the tax season and your return is straightforward, you might see your refund within three to four weeks of filing. If you filed later or your return required additional review, it may take longer.
If you filed electronically and chose direct deposit, your refund will not be mailed as a check. The 310 code confirms this — your money is coming by electronic transfer only.
What to do if your refund shows 310 but has not arrived
If five or more business days have passed since the IRS released your refund and you still do not see the money in your account, start by contacting your bank. Ask them to confirm whether the deposit was received on their end. Sometimes a bank's internal processing can delay a deposit from showing up in your account, even though the IRS sent it. Your bank can tell you the exact date and time they received the transfer and when it will be available to you.
If your bank confirms they never received the deposit, or if the IRS shows the refund was released but you are unsure of the exact date, use the Where's My Refund tool again to check the current status. The tool may show a different code if something changed — for example, if the IRS had to hold your refund for additional review, the code might change from 310 to something else. Write down the date the tool says your refund was released.
If the IRS says the refund was released more than five business days ago and your bank says they never received it, contact the IRS directly at 1-800-829-1040. Have your Social Security number, filing status, and the refund amount ready. The IRS can investigate whether the transfer was sent to the correct bank account number and routing number, which are the most common reasons a direct deposit refund goes missing.
Other refund delivery codes and what they mean
The IRS uses several codes to describe how your refund will reach you. Code 310 is direct deposit. Code 320 means the IRS will mail you a paper check. Code 330 means your refund will be loaded onto a prepaid debit card issued by the IRS — this method is less common and usually only happens if you requested it specifically or if the IRS could not process your direct deposit for some reason.
You may also see codes that describe the status of your refund rather than the delivery method — for example, code 846 means your refund has been approved and released. If you see 846 followed by 310, that means your refund has been approved and will arrive by direct deposit. The codes work together to tell the full story of where your refund is in the process.
If you see a code other than 310, 320, or 330 and you are unsure what it means, the IRS website has a complete list of refund codes. You can also call 1-800-829-1040 and ask a representative to explain the code on your transcript.
How to make sure your direct deposit information is correct
The 310 code only works if you provided the correct bank account number and routing number on your tax return. If you made a typo when entering your banking information, the IRS will send the refund to the wrong account, and you will have to contact the IRS to recover it — a process that can take weeks.
Before you file your return, double-check your bank account number and routing number. Your routing number is a nine-digit code that identifies your bank; your account number identifies your specific account at that bank. Both appear on the bottom left of your checks, or you can log into your bank's website or call their customer service line to confirm them. Enter them carefully on your tax return — even one wrong digit can send your refund to the wrong place.
If you already filed and you realize your banking information was wrong, contact the IRS as soon as possible. You can call 1-800-829-1040 or use the IRS's online account at irs.gov to update your information before the refund is released. Once the refund has been released (marked with code 310 or 846), you cannot change the bank account it is going to, and you will need the IRS's help to recover it.
Frequently Asked Questions
Does 310 mean my refund is approved?
Code 310 means the IRS has chosen direct deposit as your delivery method, but it does not always mean your refund is approved yet. You may see 310 on your transcript before the refund is fully processed. Look for code 846 on your transcript as well — that code means your refund has been approved and released. If you see both 310 and 846, your refund is approved and on its way by direct deposit.
Can I change my refund from 310 to a check if I want?
Once the IRS has processed your return and assigned code 310, you cannot change it to a check. If you want to receive your refund by check instead, you would have to file an amended return, which takes much longer. If you have not yet filed, you can choose check delivery on your original return before you submit it.
What if my bank account closed before my refund arrived?
If the bank account you listed on your return has been closed, the IRS will attempt to deposit your refund anyway. The deposit may be rejected by your bank, and the IRS will then mail you a check instead — a process that can add two to four weeks to your wait time. If your account closed, contact the IRS at 1-800-829-1040 before your refund is released so they can update your banking information or switch you to a check.
How do I know if my bank received the 310 refund?
Log into your bank account online or call your bank's customer service line and ask whether a deposit from the IRS has been received. Your bank can see all incoming transfers, even if they have not posted to your account yet. If your bank confirms the deposit was received, ask when it will be available — sometimes deposits take an extra day to process on the bank's end.
