* The Do Not Pay Until April 2027 Promotion (the "Promotion") will run from 10/12/2026 until 10/31/2026, unless extended by Paychex (the "Promotion Period"), and is subject to the following terms and conditions. The Promotion will consist of free payroll services from the date an Eligible Client commences payroll processing through April 2027, with up to six (6) free months. The earlier an Eligible Client begins processing payroll with Paychex, the greater the number of free months it will receive. An "Eligible Client" is a client that: (1) is a new sales client, and is not currently receiving payroll services from Paychex (an add-on ID to an existing Paychex client is not eligible to participate in the Promotion); (2) has between 1-250 employees at the time it processes its first payroll; (3) elects a qualifying Paychex HCM bundle by entering into a one-year service agreement with Paychex. For purposes of this Promotion a qualifying Paychex HCM bundle shall be are the Paychex Foundations, Advanced and Complete HCM bundles, and the Paychex Flex® Enterprise +, Enterprise, Pro and Select bundles; (4) enters into that agreement during the Promotion Period; and (5) processes their first payroll during the Promotion Period and continues to process payroll with Paychex in accordance with the terms of the service agreement.

Paychex will credit an Eligible Client's invoice for payroll services for each month from commencement of payroll processing through April 2027. An Eligible Client must be processing payroll with Paychex in order to receive a credit for a free month, and any unused free month is not redeemable in U.S. currency or for any other entity. The value of a free month of service is equal to the quoted fees for payroll services for payrolls processed during the month and the value of the free credit may vary depending on payroll frequency and number of active workers.

The Promotion applies to the payroll component only. Eligible Clients remain solely responsible for all other fees, including, but not limited to, setup fees, NSF fees, delivery fees, premium processing fees, 401(k) services, Time and Attendance, and all other one-time fees.

The service agreement has a one-year term commencing with its first processed payroll and includes a termination clause. If an Eligible Client terminates the agreement prior to the completion of one year, Paychex will discontinue the Promotion benefits and will be entitled to recover the value of any free months provided, in addition to any other recovery for early termination in accordance with the termination clause. The Promotion is a limited time offer that is only available during the Promotion Period.
