Changing 401(k) from 1-person corp to sole proprietorship

[Guest hk73]

I had a similar problem earlier, but now the opposite way:

A corporation (S-corporation) owned by a single person is being dissolved.

Can the 401(k) plan be maintained as it is by just changing the sponsor (by corporate resolution and signature of the sole proprietor) to the sole proprietorship (= the former shareholder of the corporation)?

If yes, is there anything else to consider?

Thanks!

What does the plan provide regarding adoption by a sucessor employer? See defintion of er. One difference is that deduction for S/e person will be limited to 20% of net earnings from SE.
