In the Individual and Roth 401(k) Plans section, when I click on the first "Learn More", it says "Unlike individual 401(k) plans, Roth 401(k) plans are for businesses that have employees."
This does not appear to be true according to https://www.forbes.com/sites/jbrewer/2020/07/19/solo-[product key removed]-self-employed-business-ow....
Also, my individual 401(k) administrator sets up Roth 401(k) plans for sole proprietors without employees and they know the law in this area very well.
I didn't see anything in Publication 506 (https://www.irs.gov/pub/irs-pdf/p560.pdf) under the "Qualified Roth Contribution Program" section that says that the owner must have employees.
