Terms of use
Last updated: October 26, 2026
EINKit (einkit.com) is a free guide and SS-4 PDF helper operated by Monocube LLC, the company behind SingleFax. By using this website you agree to these terms.
Not the IRS, not advice
EINKit is independent and is not affiliated with or endorsed by the IRS. The IRS issues EINs for free. Content on this site is general information based on IRS publications, not tax or legal advice.
The SS-4 helper
The helper prepares a draft of the official Form SS-4 from the answers you enter. It does not submit an application or obtain an EIN. You are responsible for reviewing the PDF, completing any remaining fields, signing it, and confirming the current IRS fax number before you send it.
Accuracy
The IRS can change forms, fax numbers, and procedures without notice. The site is provided “as is”, without warranties of any kind, and we do not guarantee that any information is complete or current.
SingleFax services
SingleFax is a separate, paid service. Its terms of service and privacy policy apply to anything you send or buy there. Fax delivery does not establish IRS acceptance.
Acceptable use
Do not misuse the website or interfere with its operation.
Limitation of liability
To the extent permitted by law, Monocube LLC is not liable for any loss arising from your use of, or reliance on, this site, including a rejected, delayed, or duplicate EIN application.
Changes and contact
We may update these terms and will change the date above when we do. Questions: [email protected].
