Alan and the entire staff at Williamson &Co have consistently done an excellent job with our company tax needs. Alan's knowledge of 401k issues and his expertise in reviewing proposed company purchase documents was an invaluable service.

very efficient with taxes

Taxes Stress me out!

by damit janet , 04/03/2008

I was dreading to do our taxes this year because I needed to find a new accountant and did not know where to start. I asked a friend where she had her taxes done and she referred me to Williamson and Company. I am very thankful. I walked into the office late. Was greated with a no problem and a smile. Then I met Katie who walked me thru the forms and made me realize that I should not have friends do our taxes. She explained to me options on how to get my taxes reduced in the future. She also made me feel like I was her only client, knowing she is probably helping many more like me. Next year I will not be stressed come tax time, knowing that Katie and Williamson and company will take care of me.

What a Relief

by showgirl , 09/18/2007

The firm and it's staff were so helpful in answering my questions and getting my documents in order. I always file late and this firm automatically processed the extension for my returns. They even sent me a notice that I needed to get my documents in for filing since the deadline was quickly approaching. I will certainly return next year and will reccommend them to my friends and family.######If you need an experienced Accounting firm...give them a call!

Last minute tax changes

by AuntieD , 04/29/2008

As part owner in a small software company, being the consummate professional is priority one for me. With the 4/15 deadline fast approaching, a relentless travel schedule, and a last minute unexpected change to my K1, Alan Williamson and team not only reprocessed my return at the last minute, but did it within my time constraints. Literally, I was picking up the return, signing in the car, dropping in the mailbox, and dashing for the airport. Without this level of professionalism and flexibility, I would have been forced to file an extension, incurring additional penalties and interest. I highly recommend Williamson & CO for all your tax needs.
