Treasury Regulation section 301.6212-1 should be read alongside sections 6212 and 6213 when evaluating a statutory notice of deficiency and the resulting Tax Court route.
What the authority does
The regulation addresses when the district director or another authorized official may send a notice of deficiency and includes rules concerning a joint income-tax return. The statutory mailing and petition provisions remain central.
Why it matters in a tax controversy
The full notice and envelope should be preserved. The taxpayer's address history, powers of attorney, joint or separate status, prior examination correspondence, and stated petition deadline should be assembled before relying on a procedural objection.
What it does not answer by itself
The regulation does not resolve the amount of the deficiency, compute the petition deadline in every circumstance, or substitute for Tax Court filing rules and controlling cases.
Research and case checkpoints
- Confirm which authorized office issued the notice and for which periods.
- Review the address used and the IRS record of address changes.
- Check treatment of spouses when a joint return or joint notice is involved.
- Protect the section 6213 deadline while any validity issue is investigated.
