Having you review our past income tax returns and file amendments was the smartest move we’ve made recently. Because of your expertise and gentle persistence, over seventy thousand of Federal and State tax dollars were refunded to us. And, I always felt that you really cared about us.  I know you fought for every dime and were truly our advocate.  Thank you, so much.

Jacqueline, West Covina, CA (Human Resources Director)

“I just want to say thank you, Annie!  As you know my wife decided to file our taxes the last few years with a large well know tax Preparation Company. Unfortunately they are not very knowledgeable when it comes to investor type returns. Having some concerns with accuracy of our returns, I decided to call Annie.  Annie was able to amend our returns for the previous few years. Instead of having to pay tax collection bills for the prior few years, all that was reversed. Instead, we received more than ten thousand back in total! We can’t express our gratitude enough and just want you to know that you have gained our loyalty, gratitude and continued business!  Thank you Again, Annie!”

Walter, Los Angeles, CA (realtor)

Going through divorce, bankruptcy, and losing multiple properties to foreclosure all at the same time was the most stressful time of my life.  Filing a tax return that reflects all of these aspects is not an easy task, but come tax time it is the only thing I don’t stress about because of Annie and her knowledge and expertise. I’m so lucky to have her!

Julie (Investor) Orange County, CA

My husband and I thought we were millionaires until the real estate market went into the toilet. We ended up with short sales, and foreclosures. It has taken us years to eliminate the financial drain of the upside down properties… and can finally start to breathe again. If it were not for Annie Chen we would have been paying taxes on income instead of balancing off our losses. We strongly recommend anyone that is in need of expert help to look no further.

Scott and Janice, Laguna Hills, CA (realtor)

“When my husband and I short sold our home last year, one of our main concerns was the overwhelming task of filing our taxes properly. Annie did all the research for us and made the process so simple! Then, when we received some important short sale documents after already filing our taxes, Annie helped us amend our return quickly and with no problems. It was such a relief to have her expertise in this matter!” 

Jackie, Osage, WY (Pastor’s Wife)

Thank you Annie!  Due to your diligence, thorough knowledge of tax law, extensive research, perseverance, and professionalism my husband and I were able to receive $7k more in amended tax return.  I will forever be your client 🙂   Thank you.

Irma, Anaheim, CA (investigator)

With regard to the eight rental properties we owned from 2007 – 2010, Mark and I feel you helped us tremendously. Because we were not knowledgeable in the area of the tax laws, we feel your expertise helped us during these years to offset our tax liabilities with rental property expenses with write-offs unknown to us. Further, we feel you cared about us as people not just as clients because you took the time to explain different aspects of real estate investing knowledge that we were naive to. We thank you for you time, assistance, and support.

“Annie does a wonderful job at taking complicated issues and explaining them in simple terms. She is exceptionally knowledgeable and articulate. A MUST seminar for anyone who owns investment real estate or is planning to.”

M. Peters Newport Coast, CA

I dove deep into real estate investing about nine years ago never imagining that the real estate market would crash within a few years.  My saving grace has been having Annie Chen as a CPA over those 9 years.  She was extraordinarily meticulous about capturing all expenses and losses that were legally possible.  When I found myself having to short-sale or foreclose, her expertise allowed me to use those losses and other strategies to pay no taxes as I closed out each property.  I highly recommend Annie to anyone who would like the assistance of a highly ethical, hardworking and intelligent CPA.
