Three kinds of taxpayers are doing their taxes incorrectly: those who are waiting for a refund, those who are dreading doing their taxes, afraid of owing as much as they did in the prior year, and those who have actually haven't got a clue as to what their taxes will look like once the dust settles. What they all have in common is insufficient planning, and each of them should take time to sit down with a Certified Public Accountant (CPA) and start planning for next year - because good tax planning never leaves money on the table.
