No, IRS Form W-4V, which is used to request voluntary federal income tax withholding, cannot be filed online. You must complete the form and submit it directly to your payer, such as your employer or the Social Security Administration, depending on your situation. You can download the form from the IRS website, fill it out, and then send it to the appropriate entity.
DO NOT MAIL THE completed W4V to the IRS. The IRS is NOT THE PAYER. The completed form should be mailed to your nearest Social Security Office, since THEY are the payer.
To submit IRS Form W-4V, you typically send it to the payer from whom you are requesting voluntary tax withholding, such as your employer or the financial institution handling your benefits. This form does not get sent directly to the IRS. Make sure to keep a copy for your records. If you're unsure, check with the specific payer for their preferred submission method.
