Form W-4 - Employee's Withholding Allowance Certificate
From TaxAlmanac
When you hire an employee, you must have the employee complete a Form W-4 (PDF), Employee's Withholding Allowance Certificate. Form W-4 tells you, as an employer, how many withholding allowances to use when you deduct Federal income tax from the employee's pay. Form W-4 includes detailed worksheets to help the employee figure his or her correct number of withholding allowances. Employees may also want to access the withholding calculator on the IRS website at www.irs.gov/individuals for help in completing Form W-4.
If an employee qualifies, Form W-4 is also used by the employee to tell you not to deduct any Federal income tax from his or her wages. To qualify for this exempt status, the employee must have had no tax liability for the previous year and must expect to have no tax liability for the current year. However, if the employee can be claimed as a dependent on a parent's or another person's tax return, additional limitations apply. See the instructions for Form W-4. A Form W-4 claiming exemption from withholding is valid for only one calendar year. To continue to be exempt from withholding in the next year, an employee must give you a new Form W-4 claiming exempt status by February 15 of that year. If the employee does not give you a new Form W-4, withhold tax as if he or she is single, with no withholding allowances. However, if you have an earlier Form W-4 (not claiming exempt status) for this employee that is valid, withhold as you did before.
After the employee completes and signs the Form W-4, you should keep it in your files. This form serves as verification that you are withholding federal income tax according to the employee's instructions.
In the past, employers had to routinely send the IRS any Form W-4 claiming more than 10 allowances or claiming complete exemption from withholding if $200 or more in weekly wages was expected. Employers no longer have to submit these Forms W-4 to the IRS. However, Forms W-4 are still subject to review. Employers may be directed (in a written notice or in future published guidance) to send certain Forms W-4 to the IRS.
The IRS will also use information reported on Forms W-2, Wage and Tax Statement, to more effectively identify employees with withholding compliance problems. In some cases, where a serious under-withholding problem is found to exist for a particular employee, the IRS may issue a notice (commonly referred to as a "lock-in letter") to the employer specifying the maximum number of withholding allowances permitted for a specific employee. After the IRS issues a lock-in letter, if the employee wants to claim complete exemption from withholding or claim a number of withholding allowances more than the maximum number specified by the IRS in the lock-in letter, the employee must submit a new Form W-4 and a written statement to support the claims made by the employee on the Form W-4 to the IRS. The employer must disregard this new Form W-4 until the IRS notifies the employer to withhold tax based on the new Form W-4. However, if, at any time, the employee furnishes a Form W-4 that claims a number of withholding allowances less than the maximum number specified in the lock-in letter, the employer must withhold tax based on that Form W-4.
You should inform your employees of the importance of submitting an accurate Form W-4. An employee may be subject to a $500 penalty if he or she submits, with no reasonable basis, a Form W-4 that results in less tax being withheld than is required.
You should keep blank Forms W-4 for the current year on hand so you can provide them to your current and new employees. An employee may want to change the number of withholding allowances or his or her filing status on Form W-4 for any number of reasons, such as marriage, an increase or decrease in the number of dependents, or an increase or decrease in the amount of itemized deductions or tax credits anticipated for the tax year. Any of these reasons could affect the employee's tax liability. If you receive a revised Form W-4 from an employee, you must put it into effect no later than the start of the first payroll period ending on or after the 30th day from the date you received the revised Form W-4.
An employer can download and print Form W-4 from the IRS website at www.irs.gov. Taxpayers may also order Forms W-4 by calling 1-800-TAX-FORM (1-800-829-3676). TTY/TDD users may call 1-800-829-4059 to order Forms W-4. A substitute Form W-4, developed by the employer, may be used instead of the official Form W-4, if the employer also provides the tables, instructions, and worksheets contained in the Form W-4 in effect at that time. Employers may refuse to accept a substitute form developed by an employee and the employee submitting such form will be treated as failing to furnish a Form W-4.
If an employee fails to give you a properly completed Form W-4, you must withhold federal income tax from his or her wages, as if he or she were single and claiming no withholding allowances. However, if you have an earlier Form W-4 for this employee that is valid, withhold as you did before.
Any unauthorized change or addition to Form W-4 makes it invalid. This includes taking out any language by which the employee certifies that the form is correct. A Form W-4 is also invalid if, by the date an employee gives it to you, he or she indicates in any way that it is false. When you get an invalid Form W-4, do not use it to figure federal withholding. Tell the employee that it is invalid and ask for another one. If the employee does not give you a valid one, withhold taxes as if the employee was single and claiming no withholding allowances. However, if you have an earlier Form W-4 for this employee that is valid, withhold as you did before.
