In 1958, the Internal Revenue Service recognized all Rotary District & clubs in the US as exempt from federal income tax under 501 (c) (4) of the I.R.S. code. Rotary International's group exemption number is 0573.
The 1958 letter to the left is from the IRS, granting Rotary 501(c)(4) status.
Also, to the left is an important bulletin for all Rotary Clubs. It concerns your US tax status and reporting obligations to the IRS. It is important that clubs comply with the IRS regulations summarized in the bulletin. Failure to do so will jeopardize your tax exempt status.
