401(k) Auto-Enrollment Opt-Out Window — Stop Deductions Before They Snowball
What Is It?
Auto-enrollment plans can start 401(k) deferrals unless the employee affirmatively opts out or changes the rate. IRS guidance explains that employers must give employees a reasonable opportunity to make that election.
What Most People Don’t Know
- Auto-enrollment is not irrevocable.
- The notice timing matters. Employers cannot just deduct immediately with no chance to opt out.
- The deduction start date has a federal timing ceiling under the relevant auto-enrollment guidance.
Frequently Asked Questions
How quickly can auto-enrollment deductions begin after notice?
A: IRS FAQ guidance says the employer must begin deductions by the earlier of 30 days or the pay date for the second pay period after giving the employee the notice.
Can I choose a different contribution rate instead of fully opting out?
A: Yes. The affirmative election can be to opt out or to contribute a different amount than the plan’s default percentage.
