CP 90 notice
As of my last knowledge update in September 2021, there is no specific IRS notice or form
designated as “CP90.” The Internal Revenue Service (IRS) frequently updates its forms and
notices, so it’s possible that new forms or notices have been introduced since then. To get the
most current and accurate information, I recommend visiting the official IRS website or
consulting with a tax professional who is up-to-date with the latest IRS notifications and
procedures. They can provide you with accurate information regarding any notices related to
your tax situation.
