Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter D— Deferred Compensation, Etc. › Part I— PENSION, PROFIT-SHARING, STOCK BONUS PLANS, ETC. › Subpart B— Special Rules › § 414A
New 401(k) plans and 403(b) salary-reduction plans must automatically enroll workers unless the worker opts out. The automatic contribution starts between 3 percent and 10 percent of pay in the first year, then rises by 1 percentage point each year until it reaches at least 10 percent, capped at 15 percent. You can always pick a different rate, choose not to contribute, or take back automatic contributions under the permitted-withdrawal rules. If you do not pick investments, the money goes into a federally approved default investment. The rule does not apply to plans set up before the law was enacted, SIMPLE plans, or government and church plans. Employers in business less than 3 years are exempt, and small employers are exempt until 1 year after the first tax year in which they normally employed more than 10 people.
