Where Should You Mail IRS Form W-4V Upon Completion?
Taxpayers completing Form W-4V do not return their forms to the Internal Revenue Service, according to the IRS website. Instead, taxpayers submit the forms to the payers of certain benefits from which taxpayers wish to voluntarily withhold federal income tax.
Examples of payers include the Social Security Administration and state unemployment compensation administrators, according to IRS.gov.
A taxpayer downloads Form W-4V, Voluntary Withholding Request, from IRS.gov, according to the Social Security Administration. As of 2015, a taxpayer may also dial 1-800-829-1040 to request the form. After completing the form, the taxpayer returns it to the agency issuing the benefits. Filing the form is not mandatory, but a taxpayer who wishes to withhold federal income tax from benefit checks reduces the total tax due when filing his income tax return.
