Thank you Mehmet A. de Theitin for your invaluable help in setting up my company in the United States. The team was very efficient and attentive.

I had an excellent experience working with Mehmet A. His level of expertise in LLC formation, EIN applications, and ITIN processes is truly outstanding. He answered all of my questions quickly, clearly, and with a high degree of professionalism.

What stood out the most was how efficiently and reliably everything was handled. The entire process was well-structured, transparent, and easy to follow, which made a potentially complex topic feel straightforward and manageable.

If you’re looking for someone who is knowledgeable, responsive, and highly organized in handling U.S. business and tax-related matters, I can highly recommend Mehmet A.

they help me to do the federal taxes they are so professional and fast I recommend them

Thank you to TheITIN.com team!

I’m very satisfied with the services provided. From beginning to end, the team guided me through the entire process and patiently answered all of my questions—and I had a lot of them.

My situation was somewhat unique, which made the process longer than usual. However, throughout the entire 3–4 month period, they remained supportive and responsive, and we were ultimately able to successfully complete everything.

I would like to give special thanks to two team members who were primarily responsible for working with me. Mehmet A. assisted with filling out forms and preparing all the necessary documentation for the EIN setup. Ozgur was instrumental in helping me open and set up my bank account, as well as my Stripe account for the business.

With this level of service, it’s easy to remain a loyal customer.

Best regards,
Bogdan

The ITIN team provided strong support throughout my tax filing process. Their communication was clear, their response time was good, and they guided me professionally through the required steps. They prepared the documents properly and made the process smooth and manageable. Overall, a reliable service for foreign-owned U.S. company tax filing needs.

Overall, the experience went very smoothly. The support team was very helpful and responded quickly. Highly recommended.

I had an excellent experience with the entire LLC formation process.

From the very beginning, everything was handled in a professional, organized, and transparent way. The communication was clear, and I always knew exactly what step we were in and what to expect next. The whole process, including obtaining my EIN, was much smoother than I initially imagined.

I especially want to thank Mehmet A. for his support throughout the process. He was extremely helpful, responsive, and always willing to clarify my questions. Having someone knowledgeable guiding me made a huge difference and gave me a lot of confidence.

What I appreciated the most was how simple they made something that could otherwise be very complex, especially for someone dealing with U.S. company formation from abroad.

I highly recommend their service to anyone looking to open an LLC and handle EIN/ITIN processes efficiently and professionally.
