Exhibit 19.1
Insider Trading Policy
Statement of Company Policy
It is illegal to (i) buy or sell any Paychex security while in possession of material, non-public information; or (ii) to pass such information to others who then buy or sell a Paychex security. Employees who violate this policy are subject to disciplinary action by Paychex, up to and including termination, as well as potential criminal penalties, including imprisonment for up to ten years, fines up to $1 million and up to three times the profits gained or losses avoided.
A Paychex security includes Paychex stock, employee stock options, company-sponsored investment plans related to Paychex stock, and any form of Paychex security traded in the public markets regardless of whether Paychex issued the security (for example, publicly traded derivative securities, such as put or call options). This includes contributions, withdrawals, loans, changes in allocations, and transfers of 401(k) funds that affect employee's Paychex stock account balances within the Paychex 401(k) plan. It also includes transactions in Paychex securities by family members living in the same household or through other accounts the insider may control.
Prohibited Transactions
Employees may not purchase or sell a Paychex security while in possession of material, non-public information. In addition, it is illegal for employees to pass material, non-public information on to others who may then trade a Paychex security. Accordingly, employees must not:
The Insider Trading Policy discusses insider trading and explains employees' responsibilities relating to transactions in Paychex securities. There are two levels to the policy: General Standards applicable to all employees and Standards Applicable for Insiders who are required to understand and adhere to a more comprehensive level of standards.
General Standards
Except as provided below in the section titled “Trading Within Paychex Investment and Incentive Plans,” employees may not buy or sell any Paychex security while in possession of material, non-public information. Material information is any information an investor would consider important in making a decision to buy, hold, or sell Paychex securities. In short, any information that could affect the price of Paychex securities. Inside or non-public information means the information has not yet become publicly available. Release of information to the media does not immediately free insiders to trade. Insiders should refrain from trading until the market has had an opportunity to absorb the information.
Examples: Common examples of information that will frequently be regarded as material are:

Exhibit 19.1
General Standards for Insiders (apply to insiders and Section 16 employees)
Insiders are employees who are required to understand and adhere to a more comprehensive level of standards established by the Company to ensure insider trading does not take place. Insiders must comply with all the standards. These policies apply both during employment and after termination for so long as the individual is in possession of material, non-public information.
The following groups of employees are considered insiders:
Executive Assistant to the CFO may be contacted to determine if an individual is included in the above groups of

Exhibit 19.1
employees.

Exhibit 19.1
When Insiders May Buy or Sell
Insiders may buy or sell only within a Paychex "window period". The "window period" begins on the second business day after earnings are announced. The trading window will close at 4 pm Eastern Time on the date that is two weeks prior to the end of each fiscal quarter, and if such date falls on a non-business day, on the immediately preceding business day. The next "window period" would start two business days after the next quarter earnings release. However, even in a "window period" insiders cannot trade Paychex securities if in possession of material, non-public information. In addition, there will be times when the Company deems people to have "insider information" during the "window period" and may restrict trading with little or no notice.
In summary, Paychex has an established "window period" when an insider can normally expect to be able to trade but with little or no notice the "window period" may be closed for an extended period of time.
Section 16 SEC Reporting
Section 16 employees (Members of the Board of Directors, certain Executives of the Company) who execute Paychex security transactions must immediately notify Corporate Legal so a Form 4 can be filed with the SEC before the end of the second business day after the day on which the transaction occurred.
Within 2 days, Form 4 and annual Form 5 reporting to SEC is required by law. These forms document all stock transactions of a Section 16 employee, including those of the Section 16 employee's immediate family sharing their household. Immediate family includes spouse, children, grandchildren, siblings, parents, grandparents, and in-laws (but not aunts and uncles or nieces and nephews), regardless of whether the relationship arises by blood, marriage, or adoption. The timeliness and accuracy of the SEC filings is the responsibility of the individual making the filing, not Paychex. The pre-clearance of transactions by the CFO/Chief Legal Officer (CLO) and Legal's assistance with filing helps ensure the filings are timely and accurate. Failure to file or notify of stock transactions must be noted in the Paychex Annual Meeting Proxy Statement distributed to stockholders and could cause problems for the Company and the person failing to comply. Persons outside the SEC (including professional plaintiff’s lawyers) will also most likely review Section 16 filings for compliance with the law. It is the responsibility of all employees to ensure their own compliance both with the Paychex Insider Trading Policy and with all applicable laws and regulations.
Section 16 employees are prohibited from engaging in “short swing trading,” which is defined as executing both (i) a purchase of Paychex securities, and (ii) a sale of Paychex securities, during any six-month period.
Trading Within Paychex Investment and Incentive Plans (applies to ALL employees)
If an employee previously established a program of regularly scheduled purchases of Paychex stock within the Paychex, Inc. Qualified Employee Stock Purchase Program, the Paychex Dividend Reinvestment Plan, Paychex 401(k) Retirement Savings Plan, or any Paychex Deferred Compensation Plan, these purchases can continue even if the employee is in possession of material, non-public information, since the timing of the purchases is not in the employee's control.
However, an employee may only initiate, change investment allocations, increase or decrease purchases of Paychex stock, or make transfers into or from Paychex stock accounts in these plans during a "window period" and while not in possession of material, non-public information.
Stock Options (applies to ALL employees)
An employee may exercise a stock option outside the "window period" and/or while in possession of material, non-public information, if no sale of stock is involved and the option exercise price was pre-established. However, an employee cannot make a so-called "cashless" stock option exercise while in possession of material, non-public information since this type of exercise requires a sale of Paychex stock.

Exhibit 19.1
Remember, there are no valid excuses for insider trading as well as no financial hardship or small trade exceptions. Always assume trading or advice to others will be scrutinized with twenty-twenty hindsight and presume the worst outcome. Even for transactions conducted during a window period or with CFO/CLO pre-clearance, the ultimate responsibility for adhering to the Paychex Insider Trading Policy and all insider trading laws rests with each employee. It is imperative Paychex employees use their best judgment and, when in doubt, err on the side of conservatism. Any employee who has questions about specific transactions may obtain additional guidance from the Paychex Chief Financial Officer or the Chief Legal Officer who are located at the corporate office in Rochester, New York.
Exemptions to This Policy
The SEC has adopted a regulation – Rule 10-b5-1 – that allows corporate insiders to use advance trading plans to facilitate liquidity and diversification goals, and at the same time reduce the risk of insider trading allegations. A “trading plan” must be in writing and approved by the Paychex Chief Financial Officer. It must be adopted during a time when the insider adopting the plan is not in a blackout period and not aware of any material, non-public information.
The "trading plan" may (1) specify when a specific amount of Paychex securities are to be bought or sold and at what price or (2) provide a formula for determining when to buy or sell what quantity of securities and at what price.
The following provisions must be complied with to adopt a "trading plan" for the purchase and/or sale of Paychex securities:
Failure to execute a transaction in accordance with a plan will cause termination of the plan. The insider may also terminate a "trading plan" at any time. The adoption of a new plan within 90 days of terminating a plan will be subject to the same rules as a plan modification. Trading outside a “trading plan” will not be allowed until 45 days have elapsed from the termination of the plan and the insider is in an open window period.
Corporate insiders who use a “trading plan” do so at their own risk, recognizing that use of a plan may not insulate them from criminal and civil investigations and liabilities, and the public embarrassment and expense associated with defending insider trading allegations. In deciding whether to use a plan an insider should consider obtaining the advice of an experienced securities law counsel.

Exhibit 19.1
The following chart outlines the approvals and other rules applicable to transactions in Paychex securities:
Employee Group | Trading Only in the “Window Period” | CFO Approval of Trades | CFO Approval of 401(k) Paychex Stock Account Transactions | Stock Option Exercises | Section16SEC Reporting |
Board of Directors | YES | YES | YES | YES | YES |
Corporate Executives | YES | YES | YES | YES | YES |
Certain Employees Requiring Pre-Clearance | YES | YES | YES | YES | NA |
Certain Employees | YES | N/A | N/A | N/A | N/A |
Trading Only in the "Window Period" - All of the above people are subject to the "window period" requirement. Trading of Paychex securities is only allowed during the "window period" from the second business day after the quarterly earnings press release until 4 pm Eastern Time on the date that is two weeks prior to the end of each fiscal quarter, and if such date falls on a non-business day, on the immediately preceding business day. In addition to closing the “window period” at the end of each quarter, the Company may, from time to time, impose additional trading restrictions upon other persons who are affected. A trading blackout period may be extended or imposed upon little or no advanced notice, if necessary.
CFO Approval of Trades - The trading of any Paychex securities by persons notified of the requirement for pre-clearance requires documented CFO approval prior to initiating the applicable transaction. Reasonable notice (> one day) needs to be provided due to the complexity of the law and significant penalties related to non-compliance with Section 16 reporting regulations. Receipt of CFO/CLO approval for any transaction does not relieve the insider of his/her ultimate responsibility for compliance with the Paychex Insider Trading Policy and all insider trading laws. Only the individual can determine whether he/she is in possession of material, non-public information, even during an open window period. The Company does not assume responsibility for an insider’s decision to trade, even when pre-clearance has been granted for a transaction.
CFO Approval of 401(k) Paychex Stock Account Transactions - All changes to contribution or investment allocations involving Paychex stock in the insider’s 401(k) account require the documented approval of the CFO for members of the Board of Directors and Corporate Executives. Other employees who are subject to the Standards for Insiders are prohibited from making changes to 401(k) elections or allocations involving Paychex stock outside the "window period," but do not need to submit forms for CFO prior approval.
Stock Options Exercises - Members of the Board of Directors and Corporate Executives always require CFO approval prior to initiating the transaction. Director Level Insider Employees and Certain Insider Employees may not need CFO approval but will not be able to exercise options outside the "window period" since the direct interface to the broker will be unavailable during times when trading is not allowed.
