Have a professional tax preparer (CPA or EA), make sure he/she understand your business/lifestyle/goals and make sure that you understand his/her position on the recommendations given. Many individuals/small business owners tend to communicate with their tax professional when there is no time or resources to make changes to decisions they've already made; every business should have an accountant that can demonstrate the skills and knowledge to serve his/her clients and does not necessarily need to be a CPA. Unless you have a few professionals getting to know you, your business, your lifestyle, and your goals, you wouldn't need a tax attorney to determine whether you are paying the right amount of taxes.If you suggest having a tax attorney double-check your accountant's work, it means you don't trust your accountant enough and, if that's the case, replace your accountant.

There are always reasons for an accountant to make suggestions and most of the times are in the best interests of the individual/small business owner. Hence, you should listen to the accountant's reasoning for make those recommendations.
