Automatic Enrollment and Escalation: How Plan Defaults Work

A growing number of workplace retirement plans start saving for employees before they ask. Some workers welcome that nudge, while others are surprised to see a deduction on their first paycheck. Either way, it helps to know how automatic features work, because they quietly set the amount many households save. This article explains what automatic enrollment and escalation are, what the rules say, and what a household can ask about them.

Key takeaways

• Automatic enrollment means a plan deducts contributions from pay unless the employee chooses otherwise.
• Employees can generally choose to have nothing withheld or a different amount, and some plans allow a withdrawal of the automatic contributions within a limited window.
• Federal law now requires many newly established 401(k) and 403(b) plans to enroll employees automatically, with exceptions, for plan years beginning after 2024.
• Under the proposed rules, the starting default is at least 3 percent and no more than 10 percent, and it rises one percentage point a year until it reaches at least 10 percent.
• A default is a starting point set by the plan, so each household can check whether it fits its own budget, debts and goals.

What automatic enrollment means

The Internal Revenue Service explains that automatic enrollment lets an employer deduct contributions from an employee's wages unless the employee elects not to contribute or to contribute a different amount. It can be used with plans that allow salary deferrals, such as a 401(k).

Employees keep a choice. The employer must offer a chance to have nothing withheld, or a different amount, before deductions begin. Depending on the plan, an employee may also be able to withdraw the automatic contributions within a limited window, generally up to 90 days after the first one.

What automatic escalation adds

Escalation raises the default contribution on a schedule. Under proposed federal regulations published in 2025 for plans covered by the new requirement, the starting default is at least 3 percent and no more than 10 percent. It then increases by one percentage point for each later plan year until it reaches at least 10 percent, and it may not exceed 15 percent. Employees can still choose a different amount at any time.

For example, take a worker earning $60,000 a year at a plan with a 3 percent default. That is $1,800 a year, or $150 a month, before taxes. A year later at 4 percent it is $2,400. The change is small in any one month, though it adds up. The example leaves out how contributions are taxed, any employer match and investment results, so a payroll office or tax professional can say how it affects take-home pay.

What the law now requires

Under IRS Publication 560, employers with 401(k) and 403(b) plans established on or after December 29, 2022 must automatically enroll eligible employees, effective for plan years beginning after 2024, subject to certain exceptions. The proposed regulations describe exceptions for plans in place before that date, SIMPLE 401(k) plans, governmental plans, church plans, and certain new and small businesses.

In other words, an older employer plan may not have the feature, while a more recently established plan may be required to have it. The regulations were published as a proposal in January 2025, so it is worth checking whether final rules have since changed the details.

What a default is and is not

A default is a starting point chosen by the plan. It is not a judgment about what any particular worker needs. A rate that works for one household can strain another with high-rate debt or a thin cash cushion, and be too small for a household that could save more.

Contributions also go somewhere. When an employee has not chosen investments, the proposed regulations say the money must be invested according to the Department of Labor's default investment rules. It is worth finding out where your money is going and what the fees are.

Finally, the amount a worker can contribute is limited. For 2026, the IRS lists $24,500 as the 401(k) employee elective deferral limit, with higher catch-up amounts for some older workers, and a plan's terms may set a lower limit. Limits are adjusted over time.

Questions to ask about your own plan

1. Was I enrolled automatically, and at what percentage?
2. Is there a schedule that raises my percentage each year, and when does the next increase happen?
3. Can I change the percentage or stop contributions, and is there a window to withdraw automatic contributions?
4. Does my employer add money, and what do I have to do to receive it?
5. Where is my money invested if I have not chosen, and what does it cost?
6. How does the deduction fit with my emergency savings, my debts and my monthly budget?

The answers are specific to a plan and a household. Automation can make saving easier because it does not depend on remembering, but it still works best when the person it serves knows how it is set.

Common questions

Can I opt out of automatic enrollment in my workplace plan?

Yes. The Internal Revenue Service says automatic enrollment lets an employer deduct contributions unless the employee elects not to contribute or to contribute a different amount. Some plans also allow a withdrawal of the automatic contributions within a limited period.

What is automatic escalation?

It is a plan feature that raises the default contribution percentage on a schedule, often by one percentage point a year, unless the employee changes it. Under the proposed federal rules for new plans, the percentage rises until it reaches at least 10 percent.

Does every employer have to enroll workers automatically?

No. The IRS says the requirement applies to 401(k) and 403(b) plans established on or after December 29, 2022, effective for plan years beginning after 2024, and there are exceptions. Plans that existed before that date generally are not required to add it.
