Where are printable W-4 forms available?

A printable W-4 form is available in the Forms and Publications section of the Internal Revenue Service website. IRS form W-4 is the Employee's Withholding Allowance Certificate, according to the IRS.

Employees are required to complete IRS Form W-4 to indicate tax situations, including exemptions and filing status, explains the Internal Revenue Service. Employers use the form to correctly withhold the appropriate amount of federal income tax from the employee’s pay. Any time a filer’s tax situation changes, he may file a new W-4, since a change in status can affect the amount of tax being withheld from future pay.
