I didn’t think I was asking them for technical tax advice…I’m aware they cannot provide that. I thought I was just asking them how their program works - at what age their program changes from requiring information pertinent to the parent to information pertinent to the child…to me, that is specific to their system, & something technical support should be able to provide. Pub 1345 notes a differentiation (for using self-select PIN, not esignature) between under age 16 & age 16+, so I was thinking the program might use those same age levels.
I’m also aware of the language a parent would use to sign with a wet signature. I had one case using esignature where I had the parent sign & the system asked questions specific to the parent, not the 6yo child, & one where the questions were specific to the 16 yo child, so I assumed it was based on the age & wanted to understand what that age was in the PS system. I've not seen that an esignature is not allowed unless the taxpayer is the one signing. If I understand you, you’re saying only a wet signature is allowed & an esignature is not allowed unless the taxpayer is the one signing the esignature form, correct?
What I'm saying is that I think there is little to no credit report, if any at all, for a minor that DocuSign will be able to pull for verification. And I speculate that it is unlikely that DocuSign will be able to differentiate an adult not having sufficient credit history vs a minor who just isn't on the record at all, considered they don't have all of the demographic variables of the individual concerned.
E-signature can still be used but you may just need to use an alternative authentication method other than credit report-based KBA. And you should ensure that the notation “By _______________ (fill in the blanks), parent for minor child" can be added to the signature line.
I may have missed it but where in Pub. 1345 does it mention children under and over the age of 16?
Instead, I'd rely on Treas. Regs. §§1.6061-1 and 1.6012-1(a)(4) for how returns should be filed and signed by or on behalf of minors.
Since §6061(a) authorizes the Treasury Secretary to prescribe regulations which, in turn, refer to instructions issued with respect to such returns, statements, or other documents, I'd take the IRS' instructions as golden.
Given the IRS' instructions for signing minors' returns haven't changed since the beginning of e-filing and e-signature, I would apply the exact same instructions to F.8879.
