A stamped-as-received Form 1120 was a valid return, so the assessment statute of limitations had already expired

Plain-English summary

This is a short internal email from an IRS Chief Counsel attorney answering a field inquiry about whether the IRS could still assess tax against a corporation for a particular year. The question turned on the statute of limitations, which generally gives the IRS three years from the filing of a valid return to assess additional tax (section 6501). Counsel concluded that a Form 1120 the corporation had submitted, which the Service stamped as received, was a valid return that should have been processed as filed. Because that return had been filed, the clock had run and the assessment period had already expired. The practical upshot: the IRS could no longer assess tax for that year. This kind of advice matters because whether a document counts as a "valid return" controls when the limitations clock starts, and here counsel found it started (and finished) despite whatever processing issue prompted the inquiry.

Ruling snapshot

• Question: Had the statute of limitations to assess tax for the year in question expired, given a Form 1120 that the IRS had stamped as received?
• Outcome: Advice given (the return was valid; the assessment period had expired)
• Key authorities: IRC § 6501 (limitations on assessment); IRC § 6037 (S corporation returns)
