How to Sign 1040 Online

In order to go online and sign a 1040 form as a self-preparer or attach your signature to a report prepared by your tax professional, you will need to use a PDF document version of this form that contains fillable fields. This also applies if your question is how to sign 1040 for deceased taxpayers — this can be done by a spouse or legal representative of the person who passed away.
After completing the blank PDF online or uploading one with all the data filled in, proceed to sign the tax return form. PDFLiner offers extensive Sign PDF Online functionality that’s highly intuitive to navigate. When you go to the respective section of the website, you’ll see the platform’s PDF editor with a toolbar on the top of the page.

  1. Scroll to the end of the second page and click on the Signature Field. Or you can select the Add Sign button near the top left corner.
2. You’ll see the so-called Signature Wizard. This section stores any previous signatures that you may have used if you are a returning user. Alternatively, you can rely on it to quickly create a new electronic signature.
3. In the latter case, you’ll have four options. You can either type in your name to have it transformed into a handwritten style text, draw a signature with your mouse, or use an image. The image can be uploaded or taken with your camera, which you can trigger directly from the Signature Wizard.

Please note that the instrument is not specific to 1040; you can use it to sign any document.
