Our story

Helping Our Community, One Tax Return at a Time

Dean started Authoritax after volunteering for years with the a volunteer program from the IRS, preparing low-income taxpayers returns for free
He noticed that many tax preparation companies were charging unfair prices for very simple returns. 
It was there he quickly realized their was a lot of opportunity for an honest tax guy with fair pricing.
Authoritax was born…

Our MIssion…

“To solve your tax problems quickly, for the least amount of taxes, charging you only a fair price for our services, and providing spectacular value that you’ll tell your friends about..”


Don’t take our word for it – here’s what our clients say:

“Dean is efficient and so easy to work with. I’ve had many experiences over the years having my taxes done by various individuals, but never had an agent who actually took the time to get to know my family. Can not recommend enough.”

Kiran V.

Client since 2014

“Dean was awesome. My fiancé and I are both Uber drivers and Uber totally tried to screw us, Dean came to the rescue. I saved around $600 by going to him. You definitely have return customers man!”

Jenn M.

Client since 2016

“I had a complex tax issue caused by an incidence of identity theft, and Dean Ferraro did an excellent job helping me sort it out, figure out my options and get it fixed. I highly recommend Authoritax for tax needs.

David S.

Enrolled Agent

Dean will be your tax adviser and protection against the IRS. He’s saved taxpayers millions. He also teaches at local colleges to small business owners and entrepreneurs.

“An enrolled agent is a person who has earned the privilege of representing taxpayers before the Internal Revenue Service. Enrolled agent status is the highest credential the IRS awards. Individuals who obtain this elite status must adhere to ethical standards and complete 72 hours of continuing education courses every three years.

Enrolled agents, have unlimited practice rights. This means they are unrestricted as to which taxpayers they can represent, what types of tax matters they can handle, and which IRS offices they can represent clients before.” – IRS.gov

Avoiding Not Evading Tax Blog

No one enjoys paying taxes. A wiseman once called them “the cost of civilization.”
While we generally agree that tax revenues do support many fundamental aspects of our society, there will always be waste and misuse.
In this blog we’ll discuss current events at the IRS and Franchise Tax Board.

Tax law changes and ways to minimize their impact on our personal and business finances is fair game too.
As Dean says when he’s teaching college tax courses,

Let’s find a way so that you pay the lowest legal amount of taxes… to the penny.
Happy reading!
