Beneficiary designations on Paychex retirement retirement accounts carry more weight than most people realize. They override a will, control who receives the balance, and determine the tax treatment of inherited distributions. Reviewing these designations after any major life change is essential.
The transfer rules at Paychex vary across 9 retirement accounts. Below is a breakdown of beneficiary options, trust funding, and which products support each method.
- Go to https://www.paychexflex.com and sign in (registration is at the same address via Sign Up)
- Select Retirement Services or the Retirement icon
- Add or update primary and secondary beneficiaries with name, relationship, SSN, address, and share percentage
- To name a trust, use the trust's full legal name and the trust EIN -- Paychex's death-benefit form treats a trust as "Beneficiary Name (or Trust Name)" with "Beneficiary SSN (or Trust EIN)"
Required Documents
- Trust name, date established, and tax ID (EIN or SSN)
Special Requirements
- RS0016: a married participant may have only ONE primary beneficiary -- the spouse -- unless the notarized Spousal Waiver is completed
- The Spousal Waiver must be witnessed by a notary public; it cannot be done electronically
- Beneficiary forms are held by the EMPLOYER, not by Paychex, so a copy should be kept with your estate records
- RS0016 covers Paychex qualified retirement plans (401(k), profit sharing, 403(b)). The SIMPLE IRA uses its custodian's beneficiary form instead.
- Beneficiary designations override wills and other estate documents
