PRESS RELEASE OF PAYCHEX, INC. DATED JULY 11, 2007

PAYCHEX, INC. REPORTS REVISED FISCAL 2007 RESULTS

July 11, 2007

     ROCHESTER, NY, July 11, 2007 — Paychex, Inc. (“we,” “our,” “us,” or the “Company”) (NASDAQ:PAYX) has revised its previously announced earnings for the fiscal year ended May 31, 2007 (“fiscal 2007”) to recognize an additional expense charge of $25.0 million to increase its litigation reserve during the three months ended May 31, 2007 (the “fourth quarter”). Disputes involving Rapid Payroll, Inc. (“Rapid Payroll”), a wholly owned subsidiary of the Company, arose in August 2001. These disputes resulted in litigation, as has been previously disclosed by the Company. At the present time, the Company has fully resolved its licensing responsibility and settled all litigation with 74 of the 76 licensees who were provided services by Rapid Payroll. A decision favorable to Paychex, Inc. was issued by the United States District Court for the Central District of California with respect to the Company’s dispute with one of the remaining two licensees. That licensee is currently appealing the case. A verdict was issued on June 27, 2007 in litigation brought by the other remaining licensee. In that case, a California Superior Court, Los Angeles County (the “Superior Court”) jury awarded to the plaintiff $15.0 million in compensatory damages and subsequently awarded an additional $11.0 million in punitive damages.

     “We are disappointed with the recent jury decisions in the Superior Court. We believe there are substantial bases to reduce or overturn the verdict by post-trial motions to the trial court and, if necessary, on appeal. We will continue to defend our position and remain committed to resolving this case,” commented Jonathan J. Judge, President and Chief Executive Officer.

REVISED FISCAL 2007 HIGHLIGHTS

     Net income of $515.4 million, or $1.35 diluted earnings per share, for fiscal 2007, increased 11% over net income of $464.9 million, or $1.22 diluted earnings per share for the prior fiscal year. The fiscal 2007 results were impacted by the increases to the litigation reserve totaling $38.0 million, which reduced diluted earnings per share for the year by approximately $0.06 per share. In addition, with the adoption of the new accounting standard for stock-based compensation on June 1, 2006, fiscal 2007 also included $25.7 million of stock-based compensation costs.

     For fiscal 2007, operating income increased 8% to $701.5 million. Operating income excluding interest on funds held for clients, stock-based compensation costs, and the increases to the litigation reserve increased 15% to $631.1 million for fiscal 2007. Total expenses increased 16% to $1.2 billion for fiscal 2007. Stock-based compensation costs of $25.7 million for fiscal 2007 and increases to the litigation reserve of $38.0 million account for approximately 7% of the 16% increase in total expenses. Increases in personnel and technology as we continue our investments in new products and services account for most of the remaining increase in expenses.

REVISED FOURTH QUARTER FISCAL 2007 HIGHLIGHTS

     Net income was $121.1 million for the fourth quarter, or $0.32 diluted earnings per share, down slightly from net income of $122.7 million for the same period last year. Operating income was $159.9 million. Operating income excluding interest on funds held for clients ($36.8 million), stock-based compensation costs ($6.4 million), and the increase to the litigation reserve ($25.0 million) was up 14% for the fourth quarter to $154.5 million.

OUTLOOK

     Our current outlook for the fiscal year ending May 31, 2008 is based upon current economic conditions and interest rate levels. The outlook is unchanged from that included in our June 27, 2007 press release except for net income, which has been impacted by the expense charge of $25.0 million to increase the litigation reserve. Projected revenue and net income growth is as follows:

Payroll service revenue			9% — 10	%
Human Resource Services revenue			20% — 23	%
Total service revenue			11% — 13	%
Interest on funds held for clients			6% —   9	%
Total revenue			11% — 13	%
Corporate investment income			20% — 25	%
Net income			18% — 20	%

     The effective income tax rate is expected to approximate 31.5%.
