If you omitted income, failed to claim a deduction or credit to which you are believed to be entitled, or believe you are not entitled to any deduction or credit claimed on the original return, you must amend your return.
You should not amend your return if any of the following are incorrect: first or last name, social security number, direct deposit number, or date of birth.
In these cases, you should contact the Department of Treasury at (787) 622-0123 so they can guide you through the process that follows.
If you wish to amend your return from your tax profile in Taxmania, you must select the tax return you wish to amend and follow the steps. You must click on the "My Returns" button, which is on the upper right side of your account and select the tax return you wish to amend. Then, click on the "Amend" button below the "My Forms" button. Amending is free if you paid to file your tax return.
