The processing time for Form W-7 and the issuance of an ITIN can vary. Typically, it takes about 7 to 11 weeks for the IRS to process a complete and accurate application. However, during peak filing seasons, the processing time may be longer. It's important to submit your Form W-7 and supporting documentation well in advance to allow sufficient processing time. The IRS provides updates on processing times on their website, so you can check the current estimated processing time. If you need your ITIN sooner, you may be able to expedite the process by visiting an IRS Taxpayer Assistance Center or using the services of an IRS-authorized Certified Acceptance Agent (CAA). Expedited processing may involve additional fees. Consult the IRS guidelines or consult with a tax professional for guidance on expediting your ITIN application if necessary.
