Years ago, Ken helped me with some difficulties with the IRS. He patiently worked his way through the issue and was able to reduce the amount owed and have the penalty waived. And Ken's charge was very reasonable. Since then, my partner and I have over the last 8 years engaged Ken's services for our annual income taxes.

Used him for my 2020 taxes and I plan on doing so again in 2021 (and beyond!). Perfect for anyone looking to max out their returns and also cover themselves throughly on all tax matters (personal, business or otherwise)
He's well worth the money! Super responsive and highly professional.

Critical: Professionalism
This guy will offer a “free consultation” but beware, it’s not really free. He will still charge you afterwards. Does not follow through on his word. Stingy.

Spamming ads to people's private, personal newsfeed is not the way a reputable business conducts itself. This smells of desperation and a lack of ethics.

I had what I thought was a very complex tax issue pop up in which I had no previous experience with any tax issues. Ken was able to fix all of it very quickly even though I had not previously dealt with him or any cpa. I will definitely begin using him for any and all CPA and tax services! Thank you Ken!

We began working with Ken and his team in 1993 when we set up our USA company (as a subsidiary of our UK operations). Ken was endlessly helpful and guided us through the financial and tax rules that affected us in Illinois. Although most of what we did was simple enough, it was great to know that we could call Ken's office whenever we needed extra help or just a "sanity check".

Ken has been a tremendous help to me in settling both my Father and my stepmother's estates after their passing. He provided advice all along the way, as I was overwhelmed with the responsibility of being their executors. He did their taxes for 20+ years and he has helped me to do their individual returns and Estate returns as well. Responds to all my emails immediately. Very happy with Ken as our accountant.

A customer for nearly 10 years valuing the level of service AND knowledge they have provided.

As a German owned company with intercompany reporting requirements, sales in excess of $16M and unrealistic reporting deadlines - Ken and his associates have always come through for us.

Fair, knowledgeable, accommodating and insightful best describes our experiences over the years.

There are better people to choose in the area. Beware when your bill from Ken is consistently similar to any money you might be receiving back from your taxes. Also be aware when hefty bills from him continue to arrive throughout the year. Also when the IRS begins to contact you via mail with issues that you've never experienced before, consider the fact that prior to your experience with this CPA firm, nothing like that had ever occurred. Many reasons to go elsewhere. I'd advise it.

I am the Managing Partner of a national CPA firm and have had a number of our clients become clients of Ken's practice. If you need a local practitioner of individual and small business taxes he would be at the top of our list. I would refer to him without reservation.

We've been using Ken as our accountant since 2007. We have an S-Corp and own 7 rental properties. In 2007 it was our first year as an S-Corp and we had originally gone to a different accountant who didn't seem to know what he was doing. We asked around and a friend recommended Ken. Ken and his team are professional, friendly and do a great job with our complicated tax situation (including home office deductions, business related expenses for our multiple properties, investments, P&L statements for our S-Corp, etc.), all at a fair price. Some negative reviewers complained about

I would trust no one else with my taxes. We have worked with Ken for over ten years and during that time he has provided us with consistently stellar service. He is warm, committed, highly intelligent and… competent, and he seems to love tax law! Ken is our own knight in shining armor who has had to, on occasion, do battle with the forces of confusion and uncertainty that reside in the world of taxes. We heartily recommend him--and we're not even related!

I used his services once and he's a money scamming artist. Does not look for his clients best interest only for his monetary benefit. How he could sleep at night is beyond me.
It is great we have yelp to look up local businesses. I just hope people look here first before they use his services.

I've used Ken for nearing 15 years for both personal and business returns. He's gone to bat for me with the IRS, ironed out challenging tax situations and overall performed very well... particularly when I've been a number of years past-due on various items. He's incredibly knowledgable in the areas of Tax, Finance, Investments, Trusts and overall business structure.

The few negative reviewers should understand that Ken charges by the hour, as do any professionals (you have a lawyer, don't you?). Ken is very passionate about his work, he's not someone who will

Beware. I ended up paying Ken well over $1,000 for nothing. Sure, he claims he did this or that, but I never saw anything he did. No taxes, no work, no other work. I only met with him on two occasions. An initial consultation and then a 2 hour meeting. After that I never met him again until our court date. I think Ken Rapoport is a big scam.

Check out the Cook County Court website. Most CPA's have sued people zero times. Ken Rapoport has what looks like dozens. Be very careful of CPA scams.

I DO NOT RECOMMEND HIM!!!!..
I took an apointment with ken in order to do my personal and business taxes. I asked him in the first meeting how much it will cost me if he provides me the service. He said he has no idea. Then I told him it is important for me to know since I will not be able to pay high fees. Then he said my taxes are cmplicated. (I have two job, one K1, some gains and some interest income, that is all that went on my personal returns. My buiness return had 3 apartment rental income only!!. the returns were so easy to do.) So i told hime give me an idea if what he THINKS. he said
