COS Accounting & Tax provides top services as one of the leading Accounting Firms in Utah County.

I’m so glad I found COS Accounting! I’ve been a self-employed filmmaker since 2015 and I’ve been through 3 Accounting services. I’ve FINALLY found the best place. They took care of all the Covid relief paperwork, my taxes, quarterlies; all the clutter that was weighing my mind down. Now I can use my brain for writing scripts instead of stressing about tax season. I highly recommend them


I have complete confidence in COS accounting. They are truly experts. They have eased many of my business and personal financial stresses. I highly recommend them if you are looking for tax experts that can help you legally mitigate your tax liability. They are tax accountants through and through who understand how to use the tax code to your fullest benefit in accordance with your financial plans.

COS has helped me tremendously by saving me a lot more money with taxes than what I could do on my own. They are responsive and professional and have always answered my questions, of which there have been many. I have recommended my closest friends to use COS.

These guys have made it so easy for me as a 1099 guy. I’ve sold for years and I’ve always fumbled around every tax season and end up working with a friend of a friend that charges a bunch. The difference between these guys and a typical tax place is that they know and specialize on 1099.

Zach and the team have been awesome!
So far. Their legal tax strategies can save you much more than with a traditional firm. They don’t fluff things, and they tell you straight what you need to know. I’m glad to have a great accountant I can go to whenever I have questions

I’m new to having my accounting done professionally but I don’t think I could’ve made a better choice. Not only did they save me a TON of money but they are open and so willing to talk to me about everything I need to do and what works best in my situation. I have been recommending them to every person I can think.

I’ve been with COS for about a year now and it’s been a great experience. They are always on top of everything. Tax season is not stressful and is all back of the mind with their help.

Very organized accounting firm and will do anything to make sure that you have a great experience. They want to help you in any way that they can.
