IRS advised on NOL carryback refunds and suspended assessment periods

Plain-English summary

The IRS advised that a timely tentative refund claim under IRC § 6411 is governed by the net operating loss year, not the carryback year. It stated that a tentative refund under section 6411 is not an ordinary refund claim for limitations-period purposes, and that assessment periods for the affected year are suspended under sections 6501(h) and (k). The attached CCA was referenced but not included in this release.

Attachment: IRS CCA200243019

Getting back to you about your question regarding the Letter 1139 that was returned indicating that the
statute had expired for the oldest year:

I took a look at Rev. Proc. 2009-52 and discussed your question with two attorneys in my office who have
worked on the section 6411 regulations. Assuming the NOL for your taxpayer was properly carried back
to--------under the rev proc and the tentative refund claim was timely under section 6411(governed by the
NOL year, not the carryback year), we don't know why the 1139 would state the statute had expired,
either for the taxpayer to be entitled to a refund or for the IRS to examine the year. A refund under
section 6411 is not the same as an ordinary refund claim for purposes of the limitations period. In other
words, the taxpayer is not precluded from getting a refund as a result of the carryback because the 6411
claim is outside of the normal 3 year/2 year limitations period for refunds of ------- tax.

The -------is also not closed for purposes of making further assessments. The statute of limitations for
assessment is suspended under sections 6501(h) and (k). See the attached CCA.

This is the tradeoff of being able to get the quick refund under section 6411--it reopens the door to allow
the IRS to reexamine an old tax year where the assessment statute might otherwise have run.

Please let me know if you would like to discuss further or if I am misunderstanding any of the facts. But
based on what we discussed, I don't understand why the refund claim would have been denied for the ----
------ year.
