I have been using The Book Balancer for the last 2 years now to do my corporate taxes for my business Tru Cab. They have been excellent to work with and made the process so simple I really don't even remember much about my experience with them last year!
I can say this since we filed an extension and just had them wrap up our taxes before the Sept. 15th deadline. They have a great location in a nice building. I'm always greeted by a friendly smile every time I'm there. I was able to email them all of our quickbooks data so my only trip in was to sign the paperwork and pick up my copies.
They also give you a nicely bound copy to keep for your records and everything is nicely organized with copies of necessary paperwork for each of my 2 other business partners.
I primarily worked with Jennifer over there the last 2 years and I will say she went above and beyond to handle a confusion that occurred this year.
I don't have much experience working with anyone else since this is the only company I've used to file taxes but their prices seem more than reasonable and I haven't heard anything from the IRS saying we owe a lot or there were errors so their work must be good!
I'm working on starting up another LLC so maybe next year I'll have them file for 3 businesses. Thanks for everything Book Balancer!
