How to Request Social Security Tax Withholding Using Form W-4V
Verified against SSA POMS as of September 16, 2026
The short answer
Social Security Tax Withholding allows beneficiaries to voluntarily withhold federal income tax from their benefits by completing IRS Form W-4V. This process, called Voluntary Tax Withholding (VTW), lets beneficiaries opt for withholding rates of 0%, 7%, 10%, 12%, or 22%. Form W-4V is essential for adjusting these rates, except for initial MCS claims where the form is replaced by attestation. GN 02410.017 | GN 02410.015
Requesting Voluntary Tax Withholding
Beneficiaries must fill out and sign IRS Form W-4V to request, stop, or change Voluntary Tax Withholding (VTW). For initial claims processed through the Modernized Claims System (MCS), the VTW request is electronically managed and acknowledged without a physical form. Beneficiaries can choose to withhold at rates of 0%, 7%, 10%, 12%, or 22%. Each change or setup of a withholding action needs a separate Form W-4V. GN 02410.017.A

Typically, a Field Office or Teleservice Center handles VTW requests unless there are exceptions. For exceptions due to system input or multiple entitlements, Processing Centers are involved. After processing, the signed Form W-4V is kept electronically. Notify the beneficiary whenever VTW is activated, changed, or terminated. GN 02410.017.B

VTW is available for Title II beneficiaries. Title XVI, Black Lung, and other specified payments are excluded. RRB beneficiaries can also request VTW. Withholding only applies if the after-deduction payment is enough to cover the requested tax amount. All requests must use the beneficiary's Social Security Number (SSN). GN 02410.015.B
GN 02410.015 View source ›Handling of Improper VTW
If VTW is incorrectly applied, corrections must be pursued before the end of the current operating month in the tax year when the error occurred. For errors not corrected within the year, beneficiaries should seek IRS refunds. In cases where VTW was applied without a request, provide a refund if the error is detected and corrected within the same year. GN 02410.015.C
