Waiting on tax documents can be nerve-wracking. The good news is you don't have to be completely in the dark about your ITIN status. The trick is knowing which path to take, because it's different depending on your situation.
For an existing Individual Taxpayer Identification Number (ITIN), your best bet is the IRS Online Account. But if you just applied for a new one, you'll have to pick up the phone and call the IRS directly. This guide will show you exactly how to handle either scenario.
Your Quickest Ways to Check an ITIN Status#
An Individual Taxpayer Identification Number (ITIN) is a must-have for non-U.S. individuals who need to file taxes, claim refunds, or handle other federal reporting. Knowing whether your ITIN is active, pending, or expired is crucial for staying compliant.
Getting this wrong can lead to frustrating delays, especially when you’re trying to file a tax return or open a U.S. bank account. So, how do you find out where things stand?
New Applications vs. Existing ITINs#
The first question to ask is simple: are you waiting for a brand-new ITIN, or are you checking on one you already have? Your answer changes everything.
If you recently sent in a Form W-7 for a new ITIN, there’s no online portal to check its progress. It’s an old-school process that requires you to call.
On the other hand, if you already have an ITIN and just need to confirm if it’s still active, the IRS Online Account is your most direct tool.
This infographic breaks it down perfectly.

As you can see, figuring out if you're a new applicant or an existing ITIN holder is the first step. That choice dictates the method you'll use.
Over the years, the IRS has tried to make this a bit easier. To verify your status, you generally have a few options: logging into your secure online account, calling the ITIN Operations team directly at 1-800-829-1040, or digging up your original CP565 ITIN Assignment Notice. Out of all these, the online account is usually the most straightforward method available today.
Key Takeaway: Your journey to check your ITIN status begins with a simple question: Am I waiting for a new number or checking on an old one? Your answer determines whether you should pick up the phone or log in online.
Before we get into the step-by-step, it helps to understand the basics of this unique tax ID. For a complete rundown, check out our guide on what an ITIN number is and why it's so important.
Using Your IRS Online Account for ITIN Updates#
The most direct way to keep tabs on your ITIN is through your IRS Online Account. Think of it as your personal dashboard for all things tax-related, but getting access for the first time involves a serious identity check.
The IRS uses a third-party service called ID.me to make sure you are who you say you are. Be ready for a one-time, thorough verification process. You'll need to upload photos of a government-issued ID and might even have to do a quick video call with an agent. It’s a bit of a hurdle, but it’s crucial for protecting your sensitive financial data.
Finding ITIN Notices in Your Account#
Once you’re in, you can skip the anxiety of waiting for snail mail. Your account gives you instant access to official IRS letters. The most important spot for you is the "Notices and Letters" section on your dashboard.
This is where the IRS posts digital copies of any correspondence they send you. For ITIN holders, two specific notices are critical:
- CP48 Notice: This is a heads-up that your ITIN is set to expire at the end of the year. If you still need to file a tax return, you must renew it.
- CP748 Notice: This is another reminder letter, serving the same purpose as the CP48 by telling you that your ITIN’s expiration date is coming up.
Seeing one of these notices in your account is the clearest sign you need to take action. It cuts out all the guesswork and lets you get ahead of the problem.
Your IRS Online Account is essentially a digital mailbox for critical tax documents. Checking it regularly is the most proactive step you can take to manage your ITIN and avoid headaches come tax season.
What About Checking a Renewal Application?#
Here’s where it gets a little tricky. While the online account is perfect for seeing official notices about an existing ITIN, it has its limits. The IRS does not have an online tool to track the real-time status of a renewal application you’ve already sent in.
For that, you still have to pick up the phone and call the IRS helpline. ITIN renewal processing times usually run between 7 to 11 weeks. Tax experts specializing in expat issues often provide detailed insights on what to expect during this waiting period.
This is a key distinction to remember: use your online account to monitor the overall health and expiration status of your ITIN, but use the phone to check on a pending renewal.
Checking a Pending ITIN Application by Phone#
If you recently mailed in a Form W-7 for a new ITIN, you might be trying to figure out how to check my itin status online. The catch is, your online IRS account won't show anything about a pending application. In this situation, the best and most reliable move is to call the IRS directly.
When you call, you'll be connected with the ITIN Operations team.
- From inside the U.S., dial 1-800-829-1040.
- If you're outside the United States, you'll need to call 1-267-941-1000. Just keep in mind this is not a toll-free number.
Prepare for Your Call to the IRS#
To make the call as smooth as possible, get your documents together before you dial. An IRS representative needs to verify who you are before they can share any details about your application.
Make sure you have this information handy:
- Your full name exactly as it appears on your Form W-7.
- Your mailing address, matching what you put on the application.
- Your date of birth.
- A copy of your Form W-7 application, if you have one.
Patience is definitely a virtue here. Wait times can get pretty long, especially during peak hours. From my experience, calling early in the morning, between 7 a.m. and 9 a.m. Eastern Time, usually means shorter holds.
Calling the IRS is your best bet when an online check isn't an option for a new application. Being prepared with your W-7 details makes the whole process faster and helps you get the answers you need.
Understanding the Processing Timeline#
It's really important to set realistic expectations for how long this takes.
According to 2022 IRS data, where nearly 3.8 million tax returns were filed using an ITIN, the standard processing time for a brand-new application is anywhere from 7 to 11 weeks. During the busy tax season from January to April, this wait can stretch even longer.

Once your application is finally approved, the IRS will mail you an ITIN assignment notice, which is a letter known as the CP565.

How to Renew an Expired or Inactive ITIN#
It can feel like a huge roadblock when you discover your ITIN has expired, especially when you’re in the middle of filing a tax return. This usually happens for one of two reasons: either your ITIN belongs to a number series the IRS has officially phased out, or it’s gone dormant after not being used on a U.S. federal tax return for three consecutive years.
The good news? The renewal process is pretty straightforward.
To get your number back in active status, you'll need to submit a new Form W-7, Application for IRS Individual Taxpayer Identification Number. When you fill it out, make sure to check the box for "Renew an Existing ITIN" and enter your previously assigned ITIN and name.

Submitting Your Renewal Application#
Here's the most critical part: you generally can't just send in the Form W-7 by itself. The IRS requires you to attach it to a valid federal income tax return, which proves you have an immediate tax-filing need for the ITIN.
There are a few rare exceptions. You might not need to file a tax return if you're a foreign student on a taxable scholarship who needs to claim a tax treaty benefit, for example. In situations like that, you must include specific documentation that proves you qualify for an exception.
The standard process is to mail your complete package which includes the renewal Form W-7, your original or certified ID documents, and your finished tax return to the IRS service center in Austin, Texas.
Once you’ve mailed the package, the waiting game starts. The typical processing time for a renewal is 7 to 11 weeks, just like a new application. During this period, you won’t be able to check its progress using any online tools. The only way to get an update on a pending renewal is to call the IRS.
Understanding how the expiration rules work can save you from future headaches. You can get into the nitty-gritty in our detailed guide on whether ITIN numbers expire. Staying informed is the best way to manage your U.S. tax obligations smoothly.
Solving Common ITIN Status Problems#
Even when you do everything right, checking your ITIN status can hit a snag. Knowing how to handle the most common issues will save you a ton of time and frustration, especially when you're trying to get your taxes filed. Let's walk through a few frequent problems and how to solve them.

The most common "problem" is simply radio silence from the IRS. The standard processing time is 7 to 11 weeks, but this can easily stretch longer during peak tax season. If you're past that 11-week mark and still haven't received your ITIN by mail, it’s time to pick up the phone and call the IRS.
When you call, an agent will ask for details to pull up your Form W-7. If they can't find any record of your application, you'll likely need to re-submit it. It's a pain, but it's better than waiting indefinitely.
Resolving Information Mismatches#
Another classic issue is getting a notice that your information doesn't match IRS records. More often than not, this is caused by a simple typo in a name, date of birth, or mailing address. It happens.
To fix it, you have to respond to the IRS notice as soon as possible. This usually means sending a letter back with the corrected information and, in some cases, providing copies of your supporting documents again. The key is to act fast to keep your application moving.
Never ignore an IRS notice. It contains specific instructions and deadlines that are critical for getting your application back on track. A quick response shows you're on top of things and avoids bigger delays down the road.
Handling a Lost ITIN Notice#
Your official ITIN assignment letter is called the CP565 Notice. For security reasons, if you lose this document, you can't just look up your number online. It's a critical piece of paper.
If your notice goes missing, you have two main options:
* Call the IRS: You can get in touch with them and request that they mail you a new copy of the notice.
* Submit a new Form W-7: If you absolutely need it and can't wait, you can file another Form W-7 to request a duplicate. Just be aware this can take several more weeks.
By knowing about these potential hurdles ahead of time, you can have the right documents ready and tackle any issues without missing a beat.
Common Questions About Your ITIN Status#
When you're waiting on an ITIN, a lot of questions can pop up. It's a process with a few moving parts, so it's natural to wonder about timelines and what certain terms mean. Here are some quick, straightforward answers to the things people ask most often.
How Long Does an ITIN Application Take?#
Patience is key here. The IRS usually takes about 7 to 11 weeks to process a Form W-7 application.
Keep in mind, this timeline can stretch out, especially during the peak tax season from January to April when their workload is heaviest. Once your application is approved, the IRS will mail you an official ITIN assignment letter, known as the CP565 Notice.
What Is the Difference Between Expired and Inactive ITINs?#
This is a common point of confusion, but the distinction is pretty important when it comes to renewing.
| ITIN Type | Reason for Status | What it Means |
|---|---|---|
| Expired ITIN | The IRS has officially phased out the number series (based on middle digits). | The number is no longer valid for tax filing until it is renewed. |
| Inactive ITIN | The number has not been used on a federal tax return for three consecutive years. | The number has become dormant due to non-use and must be renewed before filing. |
In either case, the solution is the same: you'll need to submit a new Form W-7 to renew your number before you can use it to file your taxes.
Can I Check My ITIN Status Without My Details?#
For security reasons, that's a firm no. When you call the IRS, the agent on the other end has a strict verification process. They need to match the full name, address, and birth date you put on your Form W-7. If you can't provide that exact information, they are not allowed to give you any details about your application status.
And as you think about how your ITIN fits into your overall tax picture, having a solid game plan is crucial. This essential small business tax preparation checklist is a great resource for making sure all your bases are covered.
What Should I Do if My ITIN Application Was Rejected?#
Don't panic. If your application gets rejected, the IRS will send you a letter explaining exactly why. It's often due to something straightforward, like missing a required document or a simple error on the form.
Your next step is to read that letter carefully. Once you understand the issue, gather the correct documents or fix the mistake, and then resubmit the entire Form W-7 application package.
