Consider this:

 

Every year you are required to enter into a unilateral contract with arguably one of the most powerful forces on earth, the IRS.  Based on a complex set of constantly changing rules, you are instructed to declare income on which you must pay a tax.  Pay too much and it's gone forever.  Fail to pay enough and the government has an extended period of time to collect underpaid tax plus penalties and interest.  Determining the right amount requires 3 things:

1. Knowledge of current tax laws and rules

2. Good, defensible and reliable financial information

3. An advisor that is there for you when you call

Historically, in any given year, a family's Federal and state total tax liability represents its largest single expenditure category.  Do you sincerely believe that you are serving your best interests by proceeding on your own?
