Quick answer
Mailing destinations for Form 8822-B must be verified against the current IRS source before sending anything. Tax Paperwork does not choose a service center, mail paperwork, or confirm delivery.
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 8822-B mechanics.
What to check next
Save a dated copy of the IRS instruction page used for the destination check, then keep mailing proof and any IRS correspondence with your records.
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.
