Q I have been working all year. My husband did not work during the first months of the year, but he just started a new job. How do I know if we are having the correct amount of federal income tax withheld from our checks?
A The IRS has a great ‘Withholding Calculator’ on their website at:
http://www.irs.gov/individuals/article/0,,id=96196,00.html?portlet=7
The purpose of the calculator is to help employees to ensure that they do not have too much or too little income tax withheld from their pay. It is not a replacement for Form W-4, but most people will find it more accurate and easier to use than the worksheets that accompany Form W-4.
With the information from the calculator, you can complete a new Form W-4, which you will submit to your employer.
