Natalia Moskaleva - Enrolled Agent in Carlsbad and San Diego, CA

Hassle-free ITIN & EIN application.

Give your business the footing it needs to thrive in the United States. USiBTS specializes in helping international companies and individuals get their Employer Identification Number (EIN) and Individual Taxpayer Identification Number (ITIN) quickly and seamlessly. 

What is EIN number for a company?

To open your dream company in the U.S., you need an EIN. EIN is a nine-digit number assigned by the IRS. It's used to identify the tax accounts of employers and certain others who have no employees. With this number, foreign companies can register their business, secure loans, hire employees, and operate fully.


What is ITIN number?

The IRS issues ITINs to individuals who are required to have a U.S. taxpayer identification number but who do not have, and are not eligible to obtain, a Social Security number (SSN) from the Social Security Administration (SSA).

IRS issues ITINs to help individuals comply with U.S. tax laws and to provide a means to efficiently process and account for tax returns and payments for those not eligible for Social Security numbers. They are issued regardless of immigration status, because both resident and nonresident aliens may have a U.S. filing or reporting requirement.

USiBTS will enable you to seamlessly obtain your EIN and ITIN. We will review and certify your documents, prepare application W-7 or SS-4, and deliver them to the proper IRS departments.

Our Clients Reviews

International tax client


USiBTS is the best. Not only did they help me make sound decisions, but they also followed up with me to ensure I didn’t make any other mistakes! I highly recommend them for any tax needs and financial advice. They are too good!




We were experiencing problems with our overall tax system and was on a thin line, but fortunately, we found USiBTS, which not only swooped in to save the day but resolved it quite quickly.




USiBTS handle all my personal and firm issues. After delivering me from a nightmare of complicated tax problems, everything so far has been easy. They are fast, direct, customer-oriented, and the easiest-going company I’ve ever partnered with. Kudos!



I don’t know how to thank USiBTS enough. My business would have been history if they hadn’t shown up for me. In only 24 hours, they analyzed my past tax history and put together a detailed plan, even if it was short-noticed. It was unlike anything I’ve ever seen.
