Make sure you do the consultation with them before signing any documents. They charged $575 for a simple tax return. FYI, all they did was prepare the form. Wanted them to see if I qualify for the foreign earned income tax but they didn’t know that since they didn’t do a consultation until AFTER they prepared the regular tax return. Save yourself $545 and do your taxes online. Legal scam artists.

I've been working with Langwasser for over 5 years (personally and with my LLC) and I can unabashedly say that they are an amazing group of people. I refer colleagues, friends and family whenever I can because I am very comfortable knowing how their business will be handled. I recently had to request a letter from my CPA while going through the home purchase process, and I needed it within 24 hours or else escrow would've been pushed back a week (costing at least hundreds of dollars), I called and Jackie and Karin were on it like white on rice. I called at 3:00 on a Tuesday, and had the letter

We cannot say enough about both the services of, and the people at, Langwasser & Co, CPAs. This firm has guided us through several life stages - from young salary-earning parents to putting our children through college to taking the leap and becoming business owners. Each stage would have gone very differently without the wisdom and knowledge of Karin and of Cindy, who is our primary contact at Langwasser and Co. Their professionalism and expertise are unparalleled; their kindness and humor have ensured that what can be daunting and scary is as pleasurable as possible.

Unfortunately, Karin provided the worst professional experience that I have had to date. I hired her two years ago to help with my business and personal taxes for self and entire family. I sent clients her way in that time period as well.
Unfortunately, Karin doesn't take time to review all the information provided and leaves a lot for her staff to do. She ultimately doesn't see the big picture which creates issues in the long run.
She has made several mistakes on my taxes that my financial advisor found, did not follow up on missing info, ignored information provided and made decisions

I have been with Karin for about 15 years now, she is hands down thee most knowledge, awesome CPA ever. I've recently heard some horror stories of other people's experiences with their CPA. I felt compelled to speak on the awesome level of service you get Langwasser and Co. she takes her time to explain things to you and give you advice to plan for a better future at this point she is more a part of the family I see once a year. I have referred many friends and family members here and all say she is hands down the best. If you are fortunate enough to work with Karin, you will not be disappointed

My wife and I started working with Cindy Agostini from Langwasser & Co. a couple years ago for standard tax preparation. Last year, we were randomly selected for a detailed IRS audit (for a tax year before we had started working with Langwasser & Co.). An IRS audit is extremely stressful, even if you've done nothing wrong. In our first call with Cindy, she laid out the entire audit process and what to expect at each step along the way. Everything she predicted was exactly correct. Throughout the process, it was clear that Cindy was looking after our interests to the fullest extent

Thank you Cindy from Langwasser for clarifying the differences between an employee and a subcontractor. I was able to restructure my contracts to help avoid EDD problems in the future. As an employer with subcontractors, this information is invaluable to me. If you are looking for accounting or tax help, the folks at Langwasser know their stuff.

Shawn, Karin and the rest of the folks at Langwasser are A+. They're fast, extremely knowledgeable, and really know how to help their clients navigate the tricky issues that businesses face with accounting, finances and even M&A. While not the cheapest firm, you get what you pay for with their people, knowledge and services. The cost savings you may get with another firm could end up costing you exponentially more without the experts at Langwasser by your side. If peace-of-mind and a solid bottom-line with no bloated expenses is important to you, than you will appreciate this firm.

When my mother passed away, I needed some advice on her trust. Langwasser & Company CPAs charged me over $200 for less than one hour of verbal advice. I was told that just to get something called an EIN, it would cost over $1000. I later found out an attorney would have done the same thing for less than half. The attorney told me it only takes a couple of weeks to get an EIN. It took Langwasser & Company CPAs over 3 months.
I had 3 tax returns to prepare: mine, my mother's and the trust. I was charged over $3000. I gave Langwasser & Company CPAs all the necessary paperwork in

Ok, Karin is very efficient and her staff is extremely efficient as well. I have had my taxes done with a previous company and although I have nothing negative to say about them my change to Karin was the absolutely right move. Karin is also handling some other business related to consulting and I have no doubt she will continue to do a great job in that capacity as well. Karin cuts to the chase. She is prepared, the office is prepared, and what I love about her office and Karin is that they are extremely proficient and seem to value time. Nothing worse than sitting in an office and waiting, and

I have been using Cindy and Karin for over 3 years now and they provide exceptional service. They are extremely knowledgeable and most importantly accessible at any time. They are so good that I drive over an hour just to use them to do my taxes. I would highly recommend their services for any business owners. If you're looking for a professional, knowledgeable, courteous and accessible CPA look no further as their office will exceed your expectations as they have exceeded mine.
