"Significant FAQs on newly enacted tax legislation, as well as any later updates or revisions to these FAQs, will now be announced in a news release and posted on IRS.gov in a separate Fact Sheet. These Fact Sheet FAQs will be dated to enable taxpayers to confirm the date on which any changes to the FAQs were made. Additionally, prior versions of Fact Sheet FAQs will be maintained on IRS.gov to ensure that, if a Fact Sheet FAQ is later changed, taxpayers can locate the version they relied on if they later need to do so. In addition to significant FAQs on new legislation, the IRS may apply this updated process in other contexts, such as when FAQs address emerging issues.

"To address concerns about the potential application of penalties to taxpayers who rely on an FAQ, the IRS is today releasing a statement clarifying that if a taxpayer relies on any FAQ (including FAQs released before today) in good faith and that reliance is reasonable, the taxpayer will have a 'reasonable cause' defense against any negligence penalty or other accuracy-related penalty if it turns out the FAQ is not a correct statement of the law as applied to the taxpayer's particular facts."
