625.3 Minimum Requirements for an Acceptable Filing Fee
To establish an effective date of registration the U.S. Copyright Office must receive the full, applicable filing fee. To determine the correct filing fee, see the fee schedule on the Office’s website.
If the claim is approved, the effective date of registration will be the date that the Office received the correct filing fee, provided that the applicant satisfied the minimum requirements for an acceptable application and deposit copy(ies) as of that date.
