Filling it in: quick tips

Frequently asked questions
What's the difference between Form 8821 and Form 2848?
Form 8821 only lets someone see your tax information. Form 2848 (power of attorney) lets a qualified representative act for you.
Is my information uploaded?
No. The PDF opens in this browser tab and everything you type stays on your device. Nothing is sent to a server, so your SSN, address and signature never leave your computer or phone.
Is it really free?
Yes. No trial, no subscription, no sign-up and no watermark. You download the finished PDF straight away. (Some “free” PDF fillers charge a small trial fee that turns into a monthly subscription. This one never asks for a card.)
Can I sign it here?
Yes. Press Signature to draw it with your mouse or finger, type your name in a handwriting style, or upload a photo of your signature, then place it on the signature line.
