We were happy with the consultation.Alexey was knowledgeable, and easy to talk.He took the time to listen to all our questions and explained clearly which made us feel comfortable. We appreciated his professional approach. We had a great experience and definitely recommend him to others.

I feel confident in Alexey and his team and feel I am guided in a professional and ethical manner to resolve my issues.

By far the best experience with tax related matters!!. Alexey, Yashar and the rest of the U.S. Tax IQ team are by far the most professional and knowledgable group to deal with. I would confidently recommend them to my friends and family. Thank you US tax IQ!!

Honestly didn't know what to expect going in; cross-border tax stuff between Canada and the US can get complicated fast. Alexey was great though. He broke everything down clearly without making it feel overwhelming, and actually took the time to connect all the pieces together rather than just answering questions in isolation. Walked away with a much better understanding of how to structure things properly. Would definitely recommend him if you're a Canadian looking to invest in the US and want someone who actually knows this space inside out.

I worked with Alexey and Yashar for my ITIN application. There was an initial delay due to difficult personal circumstances affecting Yashar, but I really appreciate how they handled everything afterward. Yashar filed my ITIN with the IRS and sent me the proof of filing and tracking number, which was a big relief. Alexey and Yashar were both kind, respectful, and easy to communicate with. What started out stressful ended up being a good experience, and I’m thankful for the effort they put in to make things right. I would definitely recommend them to anyone who needs help with an ITIN or cross-border tax matters.

I applied for an ITIN for the first time. Working with Alexey, Yashar and the rest of the team at US Tax IQ was very straightforward. They're knowledgeable and are able to address all concerns. But, they cannot speed up US government bureaucracy, so patience is required.

I hired Tax IQ in Oakville to help me prepare my Canadian and US taxes for 2024, and I couldn’t be happier. I did need to file in both countries, a task which seemed daunting until I was able to connect with Yashar at Tax IQ. He immediately put my mind at ease and spent far more time answering questions of mine than he needed to. My taxes were filed efficiently and properly long before they were even due. The team over there is beyond capable, and even more so, they’re really personable. I’m very happy with my choice in using this firm, and I will definitely be back for the coming tax seasons.

One of the best tax/law professionals I’ve ever had the pleasure of working with. Made every request seamless. Alexey and his team handled my US renunciation and taxes and fixed the mess previous US tax accountants created. Thank you for everything Alexey.

Last week I had a consultation at U.S. Tax IQ for a complex tax issue. Right from the start - I knew I was in good hands. The staff went over and above to accommodate my needs to conduct the meeting. We discussed my situation and they knew exactly how to start the process to help rectify the issues. My case is being handled with the utmost respect and professionalism. My mind is now at ease. Thank you, Alexey, Yashar @ U.S. Tax IQ…I highly recommend…!!!

Love professionalism and personal touch. Highly recommend.

Very helpful consultation regarding letter that I received from the IRS. Thank you Alexey.

We moved to California from Toronto a few years ago, and am so glad we found Alexey! We had a consultation before our move to make sure we were taking all the right steps to avoid complicating tax matters, and have used his tax filing services ever since. The team at U.S. Tax IQ is always quick to respond to questions, and offer quick and reliable tax filing services. I can't recommend them enough!

Our family moved from Canada to US for a new job opportunity in 2023. A colleague recommended Alexey and Tax IQ and we decided to give it a try. It turned out that this decision would be the best decision we made for the move and the cost was the best money we have spent to this date (I initially thought the price was a bit high but time has proven that every penny was worth it.) One thing you don't realize when you become a new tax resident of a new country is the amount and complexity of the paperwork involved. Alexey has always been available to speak with us (Tax season or not) and has helped us navigate this complicated tax environment in the best way possible. Plus he and his team are always a pleasure to talk to and we always leave the interaction feeling heard and understood which rarely happens in Law and accounting professions these days! Thank Alexey and Tax IQ, we would have been lost without you!

Professional Services delivered in a timely basis. Will definitely use them again

I received helpful advice and will continue to come back in the future as other situations arise. Many thanks

Good advise on home sale for dual citizens, good use of time on agenda and getting the full answers in allocated time.

I am a dual citizen, I have always filed dual taxes but I had a home sale this last year and did a lot of research to find someone I trusted with my unique tax situation. Alexey was extremely knowledgeable and my meeting confirmed all of the other wonderful reviews he had on here. I would highly recommend him to anyone for their cross-border tax needs.

My wife and myself had a great experience, working with Alexey. He gave us very useful advisory information which helped us in the process of moving from Canada to US. Thank you.

Alexey is an expert when it comes to cross boarder income and US tax filing. He took the stress out of my transaction and handled it with ease.

Alexey cut out the BS and gave me straightforward and actionable advice on the tax issues related to my specific situation. He laid out the pros and cons of each choice. He not only made recommendations, but he also explained the reasons behind them. In my specific case, nothing special was required and he was honest about that instead of trying to drum up more work for himself by proposing a bunch of tax analysis. I would recommend.

It was with much anxiety that I contacted Alexey as I had recently been made aware that as a dual citizen I had tax-reporting obligations in the US despite not having lived or worked there since I was 2. Online research was scary with potential of large penalties etc. Alexey took the time to explain everything and walk me through what needed to happen to become compliant. He then made it really easy to submit everything that was needed to complete the filings. High degree of professionalism and approachability the whole way through. Highly recommend for anyone who finds themselves in my position!

I had a very complex tax situation this year since I needed to request a refund from the IRS (US) and pay that amount to the CRA (Canada). I approached Alexey and Yashar because after an unsuccessful attempt at filing my returns with another accountant. Alexey and Yashar were extremely quick, efficient and knowledgeable. Thanks to them, I was able to obtain the refund from the IRS within a few months and pay off the amount I owed to the CRA. I highly recommend this firm!

Alexey was thorough in learning about my situation and guiding me through all my options. I appreciated the online booking service for the initial consultation; it took me less than 5 minutes to get an appointment. Overall great service!

My husband is a U.S. Citizen and Canadian PR. We had a consultation with Alexy to discuss strategies for managing our assets and estate planning to optimize our tax position. He was extremely knowledgeable, helpful and answered all our questions. We finished asking our questions before the end of the hour and he took the rest of the time to probe other areas with us and offer advice which was appreciated, rather than just cut the meeting short. Would absolutely recommend if you have obligations to file with the IRS and want to avoid any issues.

Working with Alexey and the team at US Tax IQ didn't just solve my legal needs to a high level of quality, but ended up being an enjoyable experience. The small, dedicated team went above and beyond the service they offered to make me feel comfortable, valued, and well-educated in my own legal and tax history. Alexey treats his clients with respect, honesty, sincerity, clarity, and just the right balance of professionalism and personal consideration. I would recommend them whole-heartedly to anyone. I feel set up for success in my renunciation process from the US and know that the team at US Tax IQ is just an email away.
