Quick answer
The current Form 8802 instructions control who can sign for the applicant and what authorization may be needed. Tax Paperwork does not validate authority, choose a signer, attach authorizations, upload the request, pay the fee, or issue Form 6166.
Source and advice boundary
This page is education-only and not tax, legal, accounting, filing, payment, mailing, faxing, upload, confirmation, or representation advice. IRS.gov and current official instructions control Form 8802 mechanics.
What to check next
Check the current IRS instructions before signing, especially for entities, appointees, powers of attorney, fiscally transparent entities, partners, owners, beneficiaries, and foreign tax deadlines.
Tax Paperwork can help organize public-preview draft context for some narrow workflows, but the user remains responsible for official-source review, professional advice when needed, and customer-controlled submission records.
Common risk
The common mistake is treating a draft, checklist, payment receipt, upload receipt, mailing receipt, or third-party summary as IRS confirmation. Keep records, but verify official channel rules and follow-up through IRS.gov, official correspondence, or qualified professional help.
