"She made a $26,000 error in favor of the IRS on an electronically filed tax return. I identified the mistake only after the return had already been submitted. When I brought this serious error to her attention, her response was dismissive—she simply stated, “Everyone makes mistakes,” and offered no apology or accountability.

Despite the error being entirely hers, she charged me $65 to file an amended Form 1040 to correct it. That amendment was never successfully processed. She then demanded an additional $65 to resubmit the Form 1040X, which also failed. As a result of her repeated mistakes and incompetence, I was forced to file a paper Form 1040X myself.

Due to this mishandling, it took nearly three years for me to recover the $26,000 owed to me by the IRS. Her lack of professionalism, accountability, and competence caused significant financial stress and unnecessary delay. She is one of the worst CPA/tax professionals I have ever dealt with."

    Looks like we had similar experiences. My experience was disappointing to say the least. She made several oversites with my federal and state taxes. I... had to point out the errors I observed when she provided me the final versions. I had to file two state returns for Texas and Wisconsin. After she submitted the return for Wisconsin, I received a letter from them that the refund calculated was incorrect by several hundreds of dollars (not in my favor) Ellen stated it was a "software malfunction"- when I requested "some" reimbursement for her $1,600+ tax preparation fee due to her excessive errors and omissions, her response back to me was "NOT A CHANCE"- No apology or accountability to us! I cannot, with a good conscious, recommend her to anyone.  more

"Thank you for sending this Endorse for my feedback. Unfortunately, my experience with Ellen was disappointing. She did not demonstrate strong attention to detail, and several costly mistakes were identified in the preparation of my 2024 tax return.
As a first-time customer, I expected a higher level of accuracy, especially given her CPA designation. I was surprised by the number of missed items in the return she prepared. Had I not thoroughly reviewed the documents myself, the errors could have resulted in significant financial consequences for my husband and me.
I had interviewed her beforehand and felt confident in her expertise, but the final outcome did not reflect that. I will not be using her services again. I advise others to exercise caution."

    I don't know why the score is showing "2"- I did not select 2- if I had the correct options to select, I would select "0"; if that is not an option,... it would be "1".  more

"Ellen is an exceptional accountant! I cannot speak enough about how helpful she has been so far. When I firstly contacted Ellen my case was presenting may challenges and complexities for several reasons (eg both international student affiliation and working as consultant to a firm, while wife was still studying). Ellen jumped on this right away and she did a great research to identify the best way forward. She has been doing my taxes ever since (2018). Absolutely great, responsive and knowledgeable. Highly recommended!"
