How long is the ITIN application process?
The IRS cites a 7-week turnaround time to provide you with a letter outlining the decision on your application (either CP565, CP566, or CP 567). This is indicated to be longer (9-11 weeks) if during tax season – January 15 to April 30 – or if applying from overseas.

Anecdotally, we have found that the following time frames apply in most cases:
- During peak processing times (January to June), it usually takes 8-10 weeks for an applicant to receive their ITIN.
- Outside peak processing times (July to Dec), it usually takes 6-8 weeks for an applicant to receive their ITIN.
That said, in some cases, we have seen as long as 14 weeks for turnaround (even 16 weeks in the wake of COVID-19 pandemic).
Try not to be anxious if there is a delay – the IRS has to respond and return your documents, and one of the three possible notices (CP565/566/567).
