401(k) Retirement Savings

It’s all about the future. Yours.

Confluent’s 401(k) Retirement Savings Plan provides a powerful way to save for your future using pre- and/or post-tax dollars. This benefit is available to all employees, including interns. When you enroll, you can set aside a portion of your salary from each paycheck and grow your savings by choosing from a range of attractive investment options offered through Fidelity.

Quick Facts

  • For 2026, you can contribute between 1% and 100% of your eligible salary each pay period less any applicable tax withholdings and benefit deductions, up to the IRS-allowed annual total contribution limit of $24,500. This amount applies to both pre-tax and Roth contributions you make.
  • If you’re age 50 and older, you can save even more by making up to an additional $8,000 in “catch-up” contributions each year.
    • If you’re age 60-63, you can make up to  $11,250 in “super catch-up” contributions.
    • If you made more than $150,000 in FICA wages with Confluent in 2025, your catch-up contributions are required to be made on a Roth basis. This will happen automatically in Confluent payroll, even if you haven’t elected to make Roth contributions.
  • After-tax contributions allow you to contribute an additional $47,500* to your 401(k) above regular contribution limits. Once you make after-tax contributions to your 401(k), you can convert that money to Roth, which allows for tax-free earnings. This strategy is commonly referred to as “mega backdoor Roth”- see the mega backdoor Roth instructions for information on how to set this up with Fidelity.
  • Your participation in the Confluent 401(k) plan is always your call. You can choose to enroll, opt-out of, or re-enroll in the plan any time you wish. You can also elect to increase or decrease the amount you set aside in the plan at any time.
  • Whether you’re new to Confluent or already enrolled in our 401(k), visit Fidelity’s site to enroll, update your contributions, or access a wealth of financial wellness content, tips, and tools.

*After-tax contributions may be limited to a lesser amount due to legally required nondiscrimination testing.

Mega Backdoor Roth

To set up Mega Backdoor Roth in your Confluent 401(k), take the following steps:

  1. Log into NetBenefits and navigate to Manage Contributions. Set your after-tax election percentage. Note it may take 1-2 pay cycles for this to update in payroll.
  2. After setting your after-tax contributions, call Fidelity at 800-835-5097 and ask to turn on “automated daily in plan conversion.” This allows Fidelity to convert any after-tax contributions you may have to Roth at the end of every business day. If you do not take this step, you may be liable for taxes on any earnings associated with your after-tax contributions.
  3. You only need to call Fidelity one time to set up automated daily in plan conversion. Once enabled, Fidelity will convert all future after-tax contributions to Roth year after year.
  4. Please note it is only beneficial to use this feature if you are already maxing out your pre-tax/Roth 401(k) contributions. See this FAQ [internal only] for more details.

New to Confluent?

Remember:

  • It can take up to two weeks from your hire date for your information to be processed with Fidelity, and then you’ll get an email from Fidelity prompting you to create an account and set your contributions.
  • Remember that 401(k) contributions made at your former employer count against the annual IRS limit. You’ll want to factor those in when setting your Confluent contributions. You are responsible for ensuring you don’t overcontribute to your 401(k).
