There are several possibilities as to why income tax is not being withheld. The most likely is that, based on how you have completed the W-4 (Employee's Withholding Certificate) that you have filed with your employer, your earnings are not enough to trigger a need for taxes to be withheld. In the TurboTax program, under Federal>Other Tax Situations>Other Tax Forms you will find Form W-4 and estimated taxes. In this section, it will help you complete a W-4 for the current year based on the information you enter. If this reflects that withholding are not necessary and you still desire to have tax withheld, you can decrease the number of dependents you are claiming on your W-4 (this does not affect what you actually claim on your Form 1040 or you can claim an amount on line 4(c) Extra Withholding on your Form W-4. Please keep in mind that you are allowed to file a W-4 through out the year.
