27 CFR 73.31: May I submit forms electronically to TTB?

Yes; to satisfy any requirement to submit forms in this chapter (including a requirement to submit an original form or copies), you may submit an electronic form or you may submit, by electronic means, a copy of an original form, but only if:

(a) You submit the form through an electronic document receiving system that TTB has designated for the receipt of that specific form and for which you have registered if so required; and

(b) The conditions in any one of the following paragraphs apply:

(1) It is an electronic form that bears valid electronic signatures, as provided in subpart B of this part, to the same extent that the paper submission for which it substitutes would bear handwritten signatures;

(2) It is a copy of an original form that requires the signature of a third party who is not the person required to submit the form (such as a bond form or a power of attorney form) or a corporate seal; you submit the copy of the form electronically along with a certification that the copy is an exact copy of the original; the original bears all signatures of all required parties and any required corporate seal; and you maintain the original along with any other records required by TTB and make it available or submit it to TTB upon request; or

(3) It is a copy of a TTB form that is not available in an electronic format or it is a document other than a TTB form (that is, other than a document issued by TTB that bears an Office of Management and Budget control number) that is required to be submitted to TTB; you submit the copy electronically along with a certification that the copy is an exact copy of the original; and you maintain the original along with any other records required by TTB and make it available or submit it to TTB upon request.
