Approved ATF eForm 1 Tax Stamps are only emailed to the approved applicant, gun trust or legal entity. The ATF won't mail you a physical tax stamp. With our approved ATF eForm 1 tax stamp printing service we will pint and ship your uploaded ATF eForm 1 Tax Stamp(s) on our popular 110 lb heavy paper. This will help you turn your approved ATF eForm 1 .PDF file into a physical tax stamp that can be stored with your other approved physical tax stamps in your gun trust binder, safe, etc. Approved eForm 1 tax stamps should still be backed up digitally.
