WHERE YOU CAN FIND MORE INFORMATION

We file annual, quarterly and current reports, proxy statements and other information with the SEC. The SEC maintains an internet site at
http://www.sec.gov that contains reports, proxy and information statements and other information regarding issuers that file electronically. We maintain an internet site at https://investor.paychex.com where information about us, including SEC
filings, is also available free of charge. However, the information on, or accessible through, our internet site is not incorporated by reference in this prospectus supplement and the accompanying prospectus and you should not consider it a part of
this prospectus supplement or the accompanying prospectus. Reference to our internet site is made as an inactive textual reference.

INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

The SEC allows us to “incorporate by reference” into this prospectus
supplement and the accompanying prospectus the information in other documents that we file with it. This means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is
considered to be a part of this prospectus supplement, and information in documents that we file later with the SEC will automatically update and supersede information contained in documents filed earlier with the SEC or contained in this prospectus
supplement. We incorporate by reference in this prospectus supplement and the accompanying prospectus the documents listed below and any future filings that we may make with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange

information deemed to have been furnished and not filed in accordance with SEC rules (including Items 2.02 and 7.01 of Form 8-K):
