Start, change or end a worker's retirement plan deduction, like a 401(k), 403(b) or IRA. The employer side is described by employerMatchTiers instead of an employer amount or percentage.
Send an effectiveDate to start or change the deduction, or only an effectiveEndDate to end it. The deduction is identified by workerId and payCode. See the Guide to the Deductions API for how changes are applied.
