​​When you choose Cobalt PacWest CPAs & Tax Advisors

you can be confident you have chosen a partner with the expertise you need to succeed.  


Our services ensure our clients understand the tax implications of one or a combination of initiatives they are contemplating, tax laws, strategies and elections that apply, and the paths available to achieve their tax minimization goals.   


This allows our clients to make smart, timely and effective decisions and be in full control of their year-end tax results months - and often a year or more in advance.


At year-end, we will efficiently prepare your tax returns, locking in the tax outcomes and tax savings planned for, earned and deserved. 

Unlike typical CPAs, we encourage you to give us a call anytime you have a question, desire professional insight, have information to share, or wish to run a new tax projection scenario. The greater value we can add, the more successful you will be.
