If the IRS is knocking on your door, our tax resolution team can help you find relief—fast!

Founder and President
The IRS is a financial juggernaut that doesn’t care about the people behind the financial struggles; they simply want their money. At Diehl CPA LLC, we help shield our clients from this overbearing government agency to help them overcome financial hurdles and stressful times with years of hands-on tax experience!
Most of this takes place without you ever coming to our offices. We live in a day and age where technology makes it easy for us to represent you no matter where you reside. Of course, you can always come to our offices if you prefer, whatever is more convenient for you.

Consultation
Meet with our tax experts online and tell us your story. We will use this time to listen and understand your situation thoroughly.

Investigation
After our initial consultation, our experts will take over all communication with the IRS and start creating your personalized tax relief strategy.

Resolution
Now we put our plan into action. Our tax experts will execute our strategy and negotiate with the IRS on your behalf until we secure the relief you deserve.

Diehl CPA is the expert in solving your tax problems quickly and efficiently. We offer a free initial consultation to review your case and explain your options. We generally work on a “flat” (fixed) fee basis, so you will know how much in fees, upfront, it will take to resolve your problem.

Go-getter and genuine expert are a few of the phrases that come to mind when I think about Mark. He is a detail-oriented, target-oriented, ambitious, and strong worker. His knowledge is vast and extensive. He always takes care of the job.

Mark Diehl has been a fantastic accountant. Not only have I rarely ever been sent to his voice mail, as he answers which is incredible for immediate information, but he has saved me $$$ time and time again. Most recently, he asked me about a business transaction that I had NO idea existed. RECOMMEND him HIGHLY!!!

Mark is very friendly, helpful, and knowledgable. He was easy to talk with and did a great job. I would highly recommend him to anyone looking for CPA services!
