Resale certificates, done in about a minute. Vendors ask for a sales tax resale certificate before they will sell to you tax-free. EZ Exempt keeps your business details on file and turns them into a signed, ready-to-send PDF for any state. THE STATE'S OWN FORM Most tools hand you a generic document that vendors reject. EZ Exempt fills the actual form your state publishes — Texas 01-339, New York ST-120, California CDTFA-230, Arizona 5000A, Illinois CRT-61, Michigan 3372 and many more. Where a state publishes no form of its own, EZ Exempt uses the multistate certificate that state accepts, and tells you which one it used and why. HOW IT WORKS • Enter your business details once • Pick a state — your own is pinned to the top • Answer the questions that state actually asks • Sign with your finger, straight into the PDF • Email it to the vendor, save it to Files, or share it anywhere BUILT FOR RESELLERS • All 50 states and the District of Columbia • Blanket or single-purchase certificates • Out-of-state permits handled — most states accept your home-state registration number, and EZ Exempt puts it in the right box • Save vendors so the next certificate takes seconds • Every certificate you generate is kept, ready to resend • Instruction pages are stripped, so the vendor gets the certificate and nothing else PRIVATE BY DESIGN Your company name, address, EIN, permit numbers, and signature never leave your device. There is no account, no sign-in and no cloud sync. Certificates are generated on your iPhone and only go anywhere when you choose to send them. EZ Exempt is free, supported by ads. A one-time in-app purchase removes them. EZ Exempt is published by Daedalus TCG LLC and is not affiliated with, authorized by, or endorsed by any state or federal tax authority. It prepares documents from the details you enter and is not tax advice. Confirm that a certificate is right for your purchase before sending it.
