Read and retain the notice
Keep every page. Identify the notice number, tax period and any response date. Follow its instructions; requesting support does not extend an IRS deadline.
Share it with the right context
Through the relevant portal process, provide the notice and any earlier response or related filing. Describe what you have already done. Use the public contact form only to arrange help, without including sensitive records.
Confirm the next action
Ask the team to confirm the scope of assistance and any authorization needed. A message or document upload does not itself appoint a representative or confirm a response has been filed.
