This number is owned by Ellis Penn, it appears that they have two locations, Denver, CO and Philadelphia, PA.  I went to the trouble to research all of these types of companies.  Names, addresses, google research, BBB research, and in some cases supreme court research.  Thousands of people hire these companies every month.  I tried to be as impartial as I could, ?just the facts.?  Some of them have multiple locations, and some of them have multiple names in the same location.  14 Linked reviews for all the companies are at the bottom of the article.  

If you want to read the article, google ?ellis penn complaints? and scroll through the results until you see:  irsbacktaxhelp.wordpress.com and click, might be on the second page of results.  It will help spread the word.

I got a call from Mackinow Corp at my place of business they said it was about a Federal Tax Matter. I returned the call and asked what type of business was Mackinow. The response was they helped companies with Federal Tax liabilities. Since I don't have a Federal Tax Liability
I hung up, let them bother someone who has a problem.

continous calls related to a federal tax issue but offers no specific info sounds like a scam

Mackinaw calls our office all the time, along with 8 or 10 other companies needing to discuss "an important tax matter".

I returned a call at my business from Danielle with Mackinaw Corp.  She asked me if I had a business at two addresses that I had never heard of and the third address was my business, she went on to say my business had a tax lien against it for over $10000.  I explained that was impossible and this information was incorrect and asked how and where she received it. When she couldn't answer my questions, I told her I wanted to speak to her supervisor. I was placed on hold and another person answered the phone and said it was a mistake.  SOME MISTAKE!!

We got a call today and my daughter answered the phone.  He said his name is John Haggers, with Mcintosh Financial.  Not sure of spelling for Mcintosh.  He told my daughter if was regarding tax issues at our address.  I did not return his call to talk to him due to not knowing whom I would be talking to.  That's why I'm on the net trying to find out about his company.
