How to designate beneficiaries at Paychex
Beneficiaries are managed online or by mail
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.

What Paychex says about beneficiaries
Each section is Paychex's own statement, with the document it comes from numbered under Sources.
Which accounts take a beneficiary1
- Employer retirement plan
Paychex's employer booklet "Your Company 401(k) Plan" states that all newly enrolled participants must complete a Beneficiary Designation.1
A trust is connected to a Paychex plan account by naming it as beneficiary, on RS0016 or in Paychex Flex. RS0016 has no separate trust section.2
Who can be named3
- A spouse, employer retirement plans
Under RS0016 a married participant has one primary beneficiary, the spouse, unless the Spousal Waiver section is completed and notarized.2
Under RS0016, if you are not married and later marry, your spouse will be your primary beneficiary unless you complete a new Beneficiary Designation Form and your spouse consents.2
- A trust, employer retirement plans
Paychex's death-benefit form RS0084 lists "individuals or revocable trusts" as non-spouse beneficiaries, and identifies a trust by its name, its EIN and the trustee's name.3
- A person, employer retirement plans
Paychex's death-benefit form RS0084 lists "individuals or revocable trusts" as non-spouse beneficiaries.3
How many beneficiaries, and how shares are split

What a designation takes to be effective

A married participant who names a primary beneficiary other than the spouse needs the spouse's signature on the RS0016 Spousal Waiver, witnessed by a notary public.2
