IRS Letter 4464C: A Detailed Guide for Taxpayers

You filed your tax return weeks ago, expecting your refund to arrive on schedule. Instead, IRS Letter 4464C showed up in your mailbox. Now you’re wondering if something went wrong with your filing, whether you made an error that’s going to cost you money, or if this delay means your refund has disappeared entirely.

These concerns are completely understandable, and you’re certainly not alone here. Thousands of taxpayers find themselves in this exact situation every tax season, often without really knowing what comes next.

Your response depends entirely on your specific circumstances. Making the wrong move could either delay your refund further or leave you vulnerable to identity theft.

This blog post will walk you through handling the 4464C letter from the IRS, from figuring out what triggered the review to taking the right steps based on your situation. You’ll also learn when calling the IRS actually helps versus when it just wastes your time.

Understanding IRS Letter 4464C

Receiving a 4464C letter from the IRS essentially means that the IRS wants to conduct a secondary review of your tax return. Now, there’s really no need to panic here; this type of verification actually happens quite frequently. What they’re doing is simply ensuring that all the information you provided on your return aligns with the records they currently have about your financial situation.

Important Details Included in Letter 4464C

Here’s what you’ll actually find when you go ahead and open this letter:

• They’re basically reviewing your return: The IRS has received your paperwork and, well, now they’re going through it pretty thoroughly to make sure all your numbers actually check out and everything looks right.
• What they’re actually looking at: It could be your income figures, those tax credits you went ahead and claimed, any money from your business ventures, or even the taxes that were already withheld from your regular paychecks throughout the year.
• You really don’t need to do anything just yet: If you’re the person who actually filed the return in the first place, honestly, just sit tight for now. Don’t really stress about it too much unless they happen to reach out to you again with specific requests.
• This stuff takes quite a bit of time: These reviews can honestly drag on for up to about 60 days or so. They actually specifically ask you not to call them before that timeframe because, well, their system probably won’t have any real updates to share with you anyway.
• What happens after all this: Once they finally finish going through everything, you’ll either get your refund as expected, they might ask you for some additional paperwork, or they could potentially reduce your refund amount (or in some cases, even deny it altogether).
• Someone else might have filed using your information: If you never actually filed that particular return yourself, it probably means someone went ahead and stole your identity and filed a fraudulent one. You’ll definitely need to report this whole mess and fill out Form 14039 to get things sorted out.
• They might reach out to other people: The IRS could potentially contact your employer, your bank, or other relevant places to verify the information you provided. They won’t go around sharing all your personal business details, though. You can actually ask for a list of who they talked to if you’re curious about it.
• Getting some help when you need it: If 60 days go by and you still haven’t heard anything back from them, go ahead and call the number that’s printed on your letter. If things get really complicated or frustrating, the Taxpayer Advocate Service will actually help you out completely free of charge.

Reasons You Might Receive IRS Letter 4464C

The IRS sends this letter when they want to take another look at your return. It’s not because you did something wrong; they just want to make sure everything adds up right.

Here’s what usually triggers it:

• Checking if you’re really you: The IRS picks some returns randomly to stop identity theft. This happens more if you moved or changed your details.
• Your refund numbers seem off: What you wrote down might not match what they have. They hold your return until they can check it.
• Testing their systems: Sometimes you get picked because they’re making sure their computers work right. Has nothing to do with your taxes.
• First time filing: New filers get looked at more carefully. They want to confirm everything’s correct and filed by the right person.
• Bigger refund than before: If your refund is much larger than last year, they notice. They want to know what changed.
• Different types of income: Switching from a regular job to self-employed work (or back) gets their attention. Income changes make them want to double-check things.

Measures the IRS Takes to Prevent Identity Theft

When the IRS holds up your return with letter 4464C, they’re trying to catch fraud before it happens. These steps help protect your identity and make sure your refund gets to you, not someone else.

Here’s what the IRS does to stop identity theft:

• Checks every return automatically: All returns go through computer filters. If something stands out, like a big refund or different income, they hold it for review and send you a 4464C letter from the IRS.
• Gives you a special PIN: You can ask for a six-digit identity protection PIN from the IRS. When you file your taxes, you enter this number so nobody else can use your information.
• Runs a protection program: The Taxpayer Protection Program looks at suspicious returns, locks down your account if needed, and helps fix problems from identity theft.
• Sends warning letters: The IRS uses letters like 4464C, 5071C, and CP01B to tell you when they need to verify who you are before sending your refund.
• Works with other groups: The IRS teams up with state tax offices, tax software companies, and banks to share information and catch fraud early.

How to Handle IRS Letter 4464C?

What you need to do depends on whether you actually filed that tax return or not. Getting this right matters for both your refund and keeping your identity safe.

If You Filed the Tax Return →

If you filed the return and everything on it is true, the IRS is just double-checking things before they send your refund. Here’s what you should do:

• Wait up to 60 days: The IRS tells you not to call before then because their system won’t have any new information anyway.
• Watch your mailbox: If they need something else from you, they’ll send another letter telling you exactly what to do.
• Check your refund status online: Use the Where’s My Refund tool or download the IRS2Go app to see if anything changes.
• Don’t lose that letter: Keep the original somewhere safe in case you need to refer to it later.
• Call after 60 days if nothing happens: If you still don’t have your refund or hear anything new, call the number on the letter.

After they finish looking everything over, the IRS will either send your refund, ask you for more paperwork, or tell you about any changes they made to your return.

If You Did Not File the Tax Return →

If you got IRS Letter 4464C but never filed a return, someone probably used your information to file a fake one. This means someone stole your identity.

Here’s what you should do:

• Call the IRS right away: Use the phone number on the letter to tell them you never filed that return.
• Fill out Form 14039: This is the Identity Theft Affidavit. Send it with a copy of your letter to the address they give you in the form instructions.
• Contact your bank and credit companies: Call your bank and at least one of the big three credit bureaus, Equifax, Experian, or TransUnion, to put a fraud alert on your accounts.
• Report it at IdentityTheft.gov: This government website helps you report identity theft and shows you what else you need to do to protect yourself.

Once the IRS confirms you never filed that return, they’ll delete the fake one and add extra security to your account. This whole process takes time, but doing these steps helps stop more problems and keeps your records safe.

When and How to Get in Touch with the IRS?

You don’t have to call the IRS the minute you get Letter 4464C. Only certain situations actually need a phone call. Calling at the right time saves you from wasting hours on hold for no reason.

When to Call the IRS?

• Call right away if you never filed that return: Use the phone number on the letter to report that someone stole your identity and filed a fake return.
• Call after 60 days if you filed but got nothing: If those 60 days passed and you still don’t have your refund or any updates, then it’s time to call the number on your letter.
• Call if they want more stuff from you: If another letter shows up asking for documents or asking questions, call the number they give you to handle it directly.

How to Call the IRS?

• Use the phone number on your actual letter: This gets you to the right people who can actually help with your specific case.
• Get your paperwork together first: Have your letter 4464C from the IRS, your tax return info, and your Social Security number right there before you dial.
• Expect to wait: Calling first thing in the morning might cut down your wait time, but you’ll probably still be on hold for a while.

Effects of Letter 4464C on Your Tax Refund

Once the IRS sends you Letter 4464C, they put your refund on pause for up to 60 days while they look over your return. Your money stays locked up during this whole time.

While they’re checking your return, the IRS might:

• Send your refund exactly as you expected, no changes, no problems.
• Ask you for more paperwork if something doesn’t make sense to them.
• Change your refund amount if they spot mistakes or numbers that don’t match up.
• Cancel your refund completely if they think someone filed a fake return or there are big problems.

Don’t bother calling the IRS while they’re doing their review. Calling before those 60 days are up won’t make them work any faster. They’ll send you another letter when they’re done looking at everything.

How to Check the Status of Your Refund?

You can track what’s happening with your refund while they look at your return:

• Use the “Where’s My Refund?” tool on the IRS website; it’s pretty easy to find.
• Enter your Social Security number, filing status, and refund amount exactly like you put it on your return.
• Don’t check more than once a day because it won’t show anything new until 24 hours pass.
• Try the IRS2Go app if you’d rather check on your phone when you’re out and about.

When the website shows your refund is still under review, there’s nothing you can do but wait. After they finish going through everything, it’ll update to show you either when your money is coming or what they need from you next.

Myths and Misunderstandings About Letter 4464C

Getting IRS Letter 4464C in the mail can honestly make anyone kind of anxious, especially when there’s so much misinformation floating around about what it actually means. So let’s go ahead and clear up some of the most common myths people have about this whole thing:

Myth 1: Letter 4464C means you’re being audited. Well, this just isn’t true at all. What’s really happening here is that the IRS is basically just taking another look at your return before they go ahead and send out your refund. It’s not actually an audit situation, more like a double-check, if you will.

Myth 2: You absolutely have to respond or something bad will happen. Most of the time, you really don’t need to do anything unless they specifically ask you for something in the letter. This is more or less just their way of letting you know what’s going on with your return.

Myth 3: Getting this letter means you definitely messed something up. That’s not really the case. The IRS sends out these letters quite regularly, actually, just to verify identities or help prevent fraud. It doesn’t necessarily mean you did anything wrong at all.

Myth 4: The delay means your refund has basically disappeared. Not exactly. Your refund is essentially just sitting there waiting while they go through their review process. It hasn’t vanished or anything; they typically finish up their checking within about 60 days or so.

Myth 5: Calling them or sending extra paperwork will somehow make it go faster. Well, unless they’ve specifically asked for something particular, calling or sending additional documents probably won’t really speed things up much. You’re honestly better off just waiting it out, as frustrating as that might be.

Myth 6: Only people with complicated returns or wealthy folks get reviewed. Actually, even pretty basic returns can get picked for this kind of review. Things like filing for the first time, getting a larger refund than usual, or having changes in your income sources can sometimes trigger this process.

Myth 7: The letter always comes through certified mail. Nope, that’s not how it works. They usually just send it via regular mail to whatever address they have on file for you. So if you’ve moved recently and haven’t updated your address with them yet, well, you might miss it entirely.

Myth 8: You can just ignore the letter and your refund will eventually show up anyway. If 60 days go by and you still haven’t heard anything back, you’ll probably need to give them a call to see what’s going on. Ignoring it altogether might actually end up making your refund take even longer to get to you.

FAQs

Q: Is IRS Letter 4464C the same as an audit?

No way. An audit is when they really dig deep into your finances and want to see receipts for everything. This letter just means they’re taking a quick look at your return before sending your refund. Happens all the time.

Q: How long does the IRS review take after sending Letter 4464C?

Up to 60 days, sometimes less. They’re basically checking if your numbers match what they already know about you. Some people hear back in a few weeks; others wait the full two months.

Q: Can I still get my refund if I receive Letter 4464C?

Yeah, most people do. Your refund isn’t gone; they just froze it while they look things over. Once they’re done checking, you’ll either get your money or they’ll tell you what’s up.

Q: What should I do if I find mistakes on my tax return after receiving Letter 4464C?

Send them the corrected version right away. It’s called an amended return. The sooner you fix the mistakes, the sooner they can wrap up their review and get you sorted out.

Q: Does receiving Letter 4464C mean there is a problem with my tax return?

Not really. Could be they picked your return randomly, or maybe something just looked different from last year. Most of the time there’s no actual problem; they’re just being careful.
