ITIN Processing Time & Cost: Full Breakdown for Non-Resident LLC Owners

How long does ITIN processing take in 2026?

ITIN applications take 7-11 weeks during peak season and 4-6 weeks during off-peak months. Processing time starts from the date the IRS receives your complete application package, not from the date you mail it.

The IRS ITIN unit in Austin, Texas processes all ITIN applications. Peak season runs from January through April when millions of tax returns are filed. Off-peak season runs from May through December when application volume drops significantly. The same processing staff handles all applications year-round, so lower volume during off-peak months translates directly to faster processing.

The 7-11 week estimate accounts for the time the IRS takes to review your Form W-7, verify your identification documents, process your accompanying tax return, assign your ITIN, and mail the ITIN assignment notice (CP 565) to your address. International mail delivery from Austin, Texas to your home country adds 1-3 weeks on top of the IRS processing time.

For non-resident Wyoming LLC owners, the total end-to-end timeline from mailing the application to receiving your ITIN is 10-18 weeks. This includes international mail transit time in both directions (if mailing original documents) and the IRS processing period.

When should you apply to get the fastest ITIN processing?

Apply between May and November for the fastest ITIN processing. The IRS ITIN unit processes applications in 4-6 weeks during off-peak months compared to 7-11 weeks during the January-April peak season.

Peak season coincides with US tax filing season. The April 15 tax filing deadline creates a surge of ITIN applications from individuals who need an ITIN to file their returns. The IRS receives the highest volume of W-7 applications in February, March, and early April. Applications submitted during these months face the longest processing delays.

The optimal strategy for non-resident LLC owners is to file your ITIN application in May or June after the peak season rush subsides. If your LLC was formed in January or February, use the time between formation and May to gather all required ITIN application documents, obtain an EIN via fax (which takes 4-8 weeks itself), and prepare your tax return.

Filing Extension Strategy

If your tax return is due April 15 and you need an ITIN to file it, you can request an automatic 6-month extension using IRS Form 4868. This moves your filing deadline to October 15, giving you time to apply for the ITIN during off-peak months and receive it before the extended deadline.

However, if you owe US taxes, the extension only extends the filing deadline, not the payment deadline. Any taxes owed are still due by April 15, and interest and penalties accrue on unpaid balances. For most non-resident Wyoming LLC owners with no US-source income, no taxes are owed, making the extension a practical strategy.

How much does an ITIN application cost in total?

The total cost of an ITIN application ranges from $0 (if you do everything yourself and mail your original passport) to $500-$800 (if you use a CAA and tax preparation service). The IRS itself charges nothing for ITIN processing.

Complete Cost Breakdown

Cost Scenarios

Here are three common cost scenarios for non-resident Wyoming LLC owners:

DIY (Lowest Cost): $30-$80

Prepare Form W-7 yourself, prepare your own tax return, mail your original passport to the IRS with tracked shipping ($30-$80). Total cost: shipping only. Your passport is unavailable for 60-90 days.

With CAA (Recommended): $100-$350

Use a Certified Acceptance Agent to verify documents ($50-$275). Prepare your own tax return. The CAA submits the application. You keep your passport. Total cost: $50-$275 CAA fee plus any translation costs.

Full Professional Service: $400-$800

Hire a CAA ($50-$275) and tax professional ($150-$500) to handle everything. The tax professional prepares your return and the CAA handles document verification and submission. Total cost includes all professional fees.

Does filing through a CAA reduce processing time?

Filing through a Certified Acceptance Agent does not reduce IRS processing time. The 7-11 week timeline applies to all ITIN applications regardless of whether they arrive from a CAA, by direct mail, or from a Taxpayer Assistance Center visit.

However, CAAs reduce the total end-to-end time in two indirect ways. First, CAAs review applications for completeness and accuracy before submission. This prevents the 8-14 week delay caused by rejections and resubmissions. An application rejected for a name mismatch must be corrected and resubmitted, doubling the total wait time. CAAs catch these errors before submission.

Second, CAAs eliminate the time your passport spends in transit. When mailing your original passport directly, you add 1-2 weeks for outbound shipping and must wait up to 60 days for the IRS to return it. With a CAA, you bring your passport to an in-person appointment and leave with it the same day.

Comparison of Submission Methods

What does IRS Form W-7 cost to file?

IRS Form W-7 costs $0 to download, complete, and submit. The IRS does not charge any fee for ITIN applications, processing, or issuance. Form W-7 is available for free download from irs.gov in PDF format.

The $0 IRS cost is a key difference between ITIN applications and other government filings. By comparison, an EIN application is also free, but LLC formation has state filing fees ($100 in Wyoming). The IRS funds ITIN processing through its general budget, not through applicant fees.

While the form itself is free, associated costs exist. Printing Form W-7 requires a printer and paper. Mailing the application requires postage. If you use tracked international shipping (recommended when sending original documents), shipping costs $30-$80 depending on your country and carrier. These costs are logistics expenses, not IRS fees.

Third-party services that charge for "ITIN filing" are charging for their preparation and submission services, not for the form or IRS processing. If a service charges $200 for "ITIN processing," that fee covers their time and expertise. The IRS portion of the cost is always $0.

Can you expedite an ITIN application?

The IRS does not offer a standard expedited processing option for ITIN applications. There is no fee you can pay to speed up processing. All applications are processed in the order received, regardless of urgency.

However, the IRS does grant expedited processing in limited circumstances. If you face an imminent tax filing deadline or a time-sensitive financial situation that requires the ITIN, you can request expedited processing by calling 1-800-829-1040 (domestic) or (267) 941-1000 (international). The IRS evaluates expedited requests on a case-by-case basis.

Situations That May Qualify for Expedited Processing

• Your tax return is due within 30 days and you need the ITIN to file
• You face IRS penalties for late filing that an ITIN would prevent
• You need the ITIN for a tax treaty benefit with a time-sensitive deadline
• A federal or state tax audit requires your ITIN

Expedited processing is not guaranteed even with a qualifying situation. The IRS may take 2-4 weeks for expedited applications compared to the standard 7-11 weeks. Approval depends on current workload and the specifics of your situation.

Alternative Strategies to Speed Up the Process

While you cannot officially expedite IRS processing, these strategies minimize total wait time:

• Apply during off-peak months: May through November processing is 4-6 weeks instead of 7-11 weeks
• Use a CAA: Prevent rejections that add 8-14 weeks per resubmission
• Submit complete applications: Incomplete applications are returned, adding weeks
• Use express shipping: Save 1-2 weeks on transit time in each direction
• Include a prepaid return envelope: The IRS uses your return envelope instead of standard mail

How do you check ITIN application status?

The IRS does not provide online tracking for ITIN applications. You can check status by calling the IRS ITIN hotline at 1-800-829-1040 (domestic) or (267) 941-1000 (international). Wait at least 7 weeks after submission before calling.

When you call the IRS, have the following information ready: the applicant's full name exactly as written on Form W-7, the applicant's date of birth, the date the application was mailed or submitted, and the mailing address listed on Form W-7. The IRS representative will look up your application and provide a status update.

IRS Phone Hours

The IRS ITIN hotline operates Monday through Friday, 7:00 AM to 7:00 PM local time (based on the caller's area code for domestic calls). International callers can reach the IRS at (267) 941-1000 during the same hours (Eastern Time). Wait times vary from 15 minutes to 2 hours depending on season. January through April has the longest hold times.

Status Responses You May Receive

• Application received and being processed: Your application is in the queue. Continue waiting.
• Additional information needed: The IRS may request additional documents. A notice will be mailed to your W-7 address.
• Application approved, ITIN assigned: Your ITIN assignment notice (CP 565) is being mailed.
• Application rejected: Your application and documents are being returned with a rejection notice.
• No record found: The IRS has not received or logged your application. Verify your shipping tracking and resubmit if necessary.

What happens if your ITIN application is rejected or delayed?

If the IRS rejects your ITIN application, all submitted documents are returned with a notice explaining the rejection reason. You must correct the issue and resubmit the complete application package. Each rejection adds 8-14 weeks to the total timeline.

The IRS rejection notice (typically a CP 567 letter) specifies exactly what was wrong with your application. Common rejection reasons include name mismatches between Form W-7 and identification documents, missing or incomplete tax returns, expired identification documents, and insufficient documentation (one document instead of two when not using a passport).

Steps After Rejection

1. Read the rejection notice carefully to identify the specific issue
2. Correct the identified problem (fix the name, update the document, complete the tax return)
3. Prepare a new complete application package (Form W-7, identification, and tax return)
4. Do not resubmit only the corrected portion; the IRS requires the full package
5. Mail the corrected application to the same IRS address in Austin, TX
6. Wait another 7-11 weeks for processing

Common Delay Causes

Beyond rejections, ITIN applications experience delays due to:

• Government shutdowns or IRS budget constraints
• High application volume during peak season
• Document verification issues requiring additional review
• Name discrepancies that require manual review (not full rejection)
• Tax return processing holds that delay ITIN assignment

To minimize delay risk, use a Certified Acceptance Agent, submit during off-peak months, and ensure your application is 100% complete before submission. Read the full document requirements in our ITIN application documents guide.

How long does ITIN renewal take?

ITIN renewal takes the same 7-11 weeks as a new application. Renewals use the same Form W-7 and require the same identification documents. The only difference is checking the "Renewal" box on Form W-7 instead of the "New ITIN" box.

ITINs expire if not used on a US federal tax return at least once in the previous three consecutive tax years. ITINs with middle digits 70-88 were systematically expired by the IRS between 2017 and 2021 under the Protecting Americans from Tax Hikes (PATH) Act. Expired ITINs must be renewed before use on a tax return.

When to Renew

Renew your ITIN if any of these apply:

• You have not used your ITIN on a tax return in the past three years
• Your ITIN has middle digits 70-88 and you have not renewed since 2017
• The IRS notified you that your ITIN has expired
• You filed a tax return and the IRS rejected it due to an expired ITIN

Renewal Timing Strategy

Submit your ITIN renewal in September or October, well before the January-April peak season. This gives the IRS time to process the renewal and issue your updated ITIN before you need to file your annual tax return. If you wait until February or March, renewal processing may not complete before the April 15 deadline.

Renewal Documents Required

ITIN renewals require the same identification documents as new applications: a valid passport (or two alternative documents), completed Form W-7 with the renewal box checked, and your current ITIN number. A tax return is not required for renewals (unlike new applications). However, if you are renewing and filing at the same time, attach the tax return.

How do you plan your ITIN timeline around LLC formation?

Plan your ITIN application to start 2-4 weeks after receiving your EIN. The EIN appears on the tax return you attach to Form W-7, so you need the EIN first. The total timeline from LLC formation to ITIN receipt is 14-26 weeks.

Do You Need an ITIN Before Operating Your LLC?

No. You do not need an ITIN to form your LLC, obtain an EIN, open a US bank account, or start accepting payments. The ITIN is only required when filing your personal US tax return. Many non-resident LLC owners operate for months or years before needing an ITIN. Read our complete guide on whether you need an ITIN for your LLC.

Your LLC's EIN is the number used for banking, Stripe, and business operations. The ITIN is your personal tax identification number used only on individual tax returns. Learn how to get an EIN without SSN and understand the difference between EIN and tax ID.
