Appeals and Tax Court are not interchangeable. Administrative Appeals reviews many IRS decisions without litigation. The U.S. Tax Court is an independent federal court. The controlling notice determines which path exists and when it must be used.
“Defense” on this independent educational site means preparing an accurate record, understanding public rights and procedures, and choosing an official response channel. The site does not defend or represent taxpayers and does not review private files.
Start with four facts
Exact notice, letter, form, report, lien, levy, or court document.
Taxpayer, entity, form, tax period, amount, and requested action.
Notice date, response date, filing date, and objective delivery proof.
Return, transcript, payment, financial, or issue-specific evidence.
Important distinctions
Written protest
An administrative protest generally organizes the disputed issues, facts, evidence, and requested result for Appeals.
Collection hearing
CDP, equivalent hearing, and CAP arise from different collection actions and carry different review rights.
Notice of deficiency
A statutory notice can permit a petition to Tax Court by the date stated on the notice.
Settlement and decision
Conference proposals, stipulations, settlement documents, and court decisions should be read for every tax period and unresolved item.
Build the working file
Use copies for the working file and keep original records secure. Create an issue index before drafting a long explanation.

Questions readers often ask
Can the IRS extend a Tax Court petition deadline?
Do not assume so. Use the last date stated on the statutory notice and verify current court instructions promptly.
Is an Appeals conference the same as a court case?
No. Appeals is an administrative forum within the IRS; the U.S. Tax Court is an independent federal court.
