What the document says“For purposes of applying section 304(b) of the Taxpayer Certainty and Disaster Tax Relief Act of 2020 (division EE of Public Law 116-260), section 301 of such Act shall be applied by substituting the date of the enactment of this section for "the date of the enactment of this Act" each place it appears.”
The section provides that in applying section 304(b) of the Taxpayer Certainty and Disaster Tax Relief Act of 2020, section 301 of that Act is applied by reading the date of enactment of this section in place of the date of enactment of that Act each place it appears.
What the document actually says“For purposes of applying section 304(b) of the Taxpayer Certainty and Disaster Tax Relief Act of 2020 (division EE of Public Law 116-260), section 301 of such Act shall be applied by substituting the date of the enactment of this section for "the date of the enactment of this Act" each place it appears.”
One date in a 2020 law is read differently. The date this law passed takes its place. That holds wherever the older date appears.
The older law sets rules for disaster losses. Moving the date widens the window. That older law is not indexed here.
No action is recorded against this proposal. That is not evidence that none has been taken, and nobody has yet read it against the record. See what the tracker does not yet cover.
