If you have any financial connections with foreign countries, you most likely need an international tax advisor. I have learned my lesson the hard way. International taxation is different and very complicated. Do not rely on your CPA which does local taxes. If you need a specialist in international taxation, USIBTS is your firm. Those guys are incredible. I am blessed that I found them when I found them. They are really good at it. I highly recommend this firm!

Natalia and Dennis are an great team. I called for a free consultation and was able to get an appointment right away. I had some problems that went back a few years, which I thought would be a pain to solve. They were able to advise me right away on how the taxes should have been done correctly and started working on filing. I was able to correct my tax issues and everything was filed correctly. I got a large refund on my last filing, which I’m very content with! Thanks USIBTS.

This is now my 8th year using US International Business Tax Solutions. Natalia always takes great care of me and is very helpful every time the daunting task of taxes comes around. She is always very informative and able to show me everything I need to know about running my business as efficiently as possible. The process is smooth and quick, and I always end up getting a much better return than anticipated! Highly recommend her work and this company for all tax needs!

Hi there! I own a business overseas and was searching for international tax specialists in San Diego County. I needed their expertise to ensure I comply with tax regulations both in the US and the country where my business operates. I also had questions about double taxation and treaties. I found USIBTS online and scheduled a consultation. They asked me to send my questions beforehand, which was convenient. Denis and Natalia impressed me with their knowledge and attention to detail. They answered all my questions and provided valuable suggestions on saving money on taxes and avoiding penalties. I had to redo my previous year’s taxes and definitely be using USIBTS to prepare my future tax returns. They’ve been great!
