The IRS only issues tax refunds when you pay more tax during the year than you actually owe. When you file exempt with your employer for federal tax withholding, you do not make any tax payments during the year. Without paying tax, you do not qualify for a tax refund unless you qualify to claim a refundable tax credit.
The tax law requires your employer to withhold federal income tax from each paycheck you receive and send it to the IRS on a quarterly basis. If you are self-employed, you are required to make income tax payments every three months throughout the year. At the end of the year, your employer provides you with a W-2 statement that reports the total amount of tax you paid during the year. When you prepare your tax return and the amount you owe is less than the total amount withheld, the IRS will refund the difference to you.
Filing exempt from withholding
When you start a job, your employer will ask you to fill out IRS Form W-4. The W-4 estimates the amount that should be withheld from each paycheck based on the tax information you provide. To claim an exemption from withholding, you must meet certain criteria. If you had even $1 of tax liability in the prior year or anticipate earning income in excess of the sum of your standard deduction and exemption, you cannot be exempt from federal tax withholding in the current year. For example, if you file as single for
2010 you must not anticipate earning income in excess of $9,350. This is a combination of your standard deduction of $5,700 and your personal exemption of $3,650. If you still file exempt and earn income in excess of this amount, unless you qualify for a refundable tax credit, it is impossible for you to receive a refund since no federal income tax is taken from your paycheck.
Claiming allowances on the W-4
If you are unable to claim exempt from withholding, you can still reduce the amount that is withheld from each paycheck by claiming allowances on your W-4. The more deductions you anticipate claiming at the end of the year, the more allowances you can take. These allowances are based on your filing status, the number of dependents you claim plus the itemized deductions you anticipate claiming such as mortgage interest, state property taxes and medical expenses. However, the IRS will impose penalties on you if you significantly underpay your actual tax liability due to filing exempt or claiming too many allowances.
Refundable tax credits
A refundable tax credit means that even if you have a zero tax liability before claiming the credit, you can still obtain a refund for a portion of the credit. For example, the American opportunity credit that covers certain higher educational expenses is 40 percent refundable. Therefore, if you qualify for the maximum $2,500 credit, you will get a refund of $1,000 (40 percent of $2,500) even if you paid no income tax for the year.
