Tax Calculation 

To aid in determining how much you should withhold, the IRS has created a withholding calculator. This calculator, while not exact, will help you in estimating your withholding amount. Please pay heed to the cautions, and notices on the web pages, as those notices could determine the ability, or lack of ability of this calculator to help in determining how much you should withhold. For more detailed estimates, you should schedule an appointment with your CPA.
