With 24 hours left to close on our home, I contacted Ilona because the lender required a specific document that no one else had ever heard of. Ilona patiently spoke to a very rude IRS employee and demanded that they provide the information I needed in my process of buying a home. Ilona is someone you can count on when you need the job done the FIRST TIME.

Where can I start? I was turned down by 3 other CPAs saying that my case is too complicated, I don't have the right paperwork, etc...My friend recommended me, Ilona. I was surprised at how fast she sorted out everything. It looked almost like magic. She has guided me through all the processes. I felt that all my questions were answered. Give her a try. You will definitely be happy with the results.

Ilona has been doing my taxes for a few years now.  Being in sales, I have many expenses that I keep track of over the year and when it comes tax time, it is difficult to account for everything. Ilona gives me the best advice on how to keep things organized and properly accounted for.  I will always use Ilona.  She is extremely knowledgeable and professional.

I have used United States Tax Services on numerous occasions and got a very fast quality service each time. Last week I needed notarized translations and received them in a number of hours. They are upfront with the price and how long the service will take and what exactly will be done. Very reliable and responsible business, I highly recommend it.

Ilona is the best!! My husband and I have used her for the past 2 years and I wouldn’t even think about going to anyone else. She’s efficient, very knowledgeable, very reasonably priced, and always easy to reach. Her office staff is very responsive as well! She’s simply the best! Thanks Ilona!

Alina S.

For the second year, we are using the service of United States Tax Services. I am amazed at how organized and professional this team is. We always get our questions answered promptly and even late at night or on weekends. Ilona takes her time explaining all the details and whatever looked to me so complicated became so clear and simple now. No doubt - they have my trust. Highly recommended!

Alex B.

Ilona filled the taxes last year for me and my wife, and was very helpful. Also we opened S-Corp with her, and ITIN and everything was fast, without any mistakes, and very professional. We had one letter from IRS for the additional information, and she immediately respond to it, and since then no more letters.
Recommend to everyone!

Very professional service. They are up on all the latest tax laws and work very hard to make sure they use the latest tax laws to your benefit. A few years ago they even found a mistake my last tax preparer had made and I got an adjusted refund !!!! Would not go anywhere else.

Jeff N.

What an amazing experience. I needed to have my taxes completed on the same day, and they were able to accommodate the request. Can you believe it, same day service during tax season? The service was affordable, the staff is very attentive to detail, and everyone in their organization that I meet were pleasant individuals to interact with! Summary: Proficient, Affordable, Pleasant, with Premier Class Service....

Need I say more???
