Official channel summary
The IRS Form 8802 page says Digital Adaptive Mobile Forms are available for individual applications and not for business entities.
The IRS Form 6166 page says Pay.gov users are required to upload a copy of the Form 8802 application when paying, but applications uploaded to Pay.gov are not processed and the complete Form 8802 application must still be submitted to the IRS residency certification function by mail or fax.
Where Tax Paperwork fits
The preview organizes known individual applicant, certification year, country, and purpose facts and creates a watermarked local draft.
It does not make Pay.gov payments, upload files, mail or fax the application, monitor status, or receive Form 6166.
When to stop
- Entity applicants, appointee delivery, partial-year or dual-status facts, unfiled-return statements, or treaty eligibility questions.
- Any urgent foreign withholding deadline where Form 6166 timing matters.
Current Tax Paperwork boundary
Tax Paperwork is not tax, legal, accounting, entity-structuring, treaty, fiduciary, valuation, or filing-channel advice. It is not IRS.gov and does not submit, transmit, fax, mail, upload, pay, or monitor IRS paperwork.
