SteveL.~Thanks for the reminder. Here is a link to the new tax law.
Automatic Revocation for Not Filing Annual Return or Notice Beginning May 17, 2010
Find help here on what must be filed to avoid
automatic revocation of tax-exempt status for organizations that fail to file for 3 consecutive years. Absent a request for extension, there is no grace period from filing by the original due date.
I forwarded LSBA's extension to the IRS on May 13, 2010.
