Standard Form 1188 (SF 1188): Cancellation of Deductions for Labor Organizations Dues
Standard Form 1188 (SF 1188), printed with the title Cancellation of Payroll Deductions for Labor Organizations Dues, is a U.S. Office of Personnel Management (OPM) form, Revised December 2025, citing 5 U.S.C. § 7115. GSA hosts a copy in its forms library, where its page lists the title as Cancellation of Payroll Deductions for Labor Organization Dues.
The Privacy Act Statement says the completed form is used to stop labor organization dues from being deducted from your pay and to notify the labor organization that the dues will no longer be deducted. The employee gives their name, identification number, agency and labor organization, and signs a cancellation statement. The reason and effective date of the cancellation are marked to be completed by agency only.
The form says the cancellation takes effect on the first full pay period beginning on or after the date the payroll office receives it, and following the initial one-year period during which deductions may not be revoked.
