There are 1.4 million accountants employed in the United States. There are 620,000 
in the U.S. 735,000 PTIN’s have been issued by the IRS. They would all love to prepare your tax return. But that’s the problem. By the time you’re ready to prepare your return (after December 31), it’s months too late to add the magic tax strategies that will cut your tax to the legal minimum. Tax preparation is just the clerical last step in the tax process.
Most tax professionals practice SALY (Same As Last Year) in which nothing ever changes.
Another sign of relative incompetence by tax professionals is that 25 million schedule C’s are filed.
