Questions about US Tax Forms

Is it free to fill a W-9 or W-4 with Wispdf?
Yes. US Tax Forms is free and unlimited, with no account needed. Fill as many W-9, W-4, 1099-NEC and 1099-MISC forms as you need. Only the optional AI fill uses AI credits: 1 AI task a day without an account, 30 credits a day with a free account, or 1,500 a month on Pro.
Is my Social Security number sent anywhere?
No. US Tax Forms runs in your browser, so the form and everything you type, including your Social Security number or EIN, stay on your device. Nothing is uploaded to our servers. If you turn on the optional AI fill, it works from a profile kept on your device, and the AI never sees your values.
Can Wispdf tell me which box to check or what to enter?
US Tax Forms explains each field in plain language, so you know what the form is asking for. It does not give tax advice. Questions about your own situation, such as your tax classification or how much to withhold, are best answered by a tax professional or by the IRS instructions for that form.
Who do I send my W-9 or W-4 to?
A W-9 goes to the business or person that asked for it, usually a client who pays you, and you do not send it to the IRS. A W-4 goes to your employer. A 1099-NEC or 1099-MISC is sent by the payer, so check the form's instructions on irs.gov before you file.
Can I fill IRS forms on my phone or Mac?
Yes. US Tax Forms works in any modern browser on iPhone, iPad, Android, Chromebook, Mac, Windows and Linux. There is nothing to install. On a phone, turning the screen sideways can make the form easier to read. Whichever device you use, the details you type stay on that device.
How do I sign and send my W-9 safely?
Once your form is filled, add your signature with Sign PDF, which is free and also runs on your device. A W-9 shows your Social Security number or EIN, so think twice before emailing it as it is. Protect PDF can add a password first, and you can share that password by text or phone.
