How to Adjust a W-4 Tax Form
Form W-4 is an IRS tax document that informs the government and your employer how much in taxes should be withheld from your paycheck every week. Your dependency status, your family situation and the size of your household all play a role in the Personal Allowances Worksheet portion of the W-4 form. If your family situation changes during the year, for example, and your W-4 form isn't adjusted to reflect it, you may be subject to federal fines.

If you need to make an adjustment to a W-4 form for a year that has already been filed, you will need to obtain Form 1040-X, which allows you to file corrections on past tax returns with the IRS. To obtain one, go to the IRS Forms and Publications page (find the link in the References section). Under Download Forms and Publications, select Form and Instruction Number (PDF). Once there, enter the term 1040-X into the Find search field, then push Find. Click on the link for Form 1040-X under the list titled Product Number. Use this form to make any adjustments that were omitted on the tax return in question. This will generally result in the IRS owing you more money, or you owing the IRS additional money. File the form by sending it to the IRS, with a check or money order if necessary.

Tips & Warnings
Form 1040-X only allows you to adjust tax returns made in the last year, so don't let necessary adjustments wait for too long.
