Jim White, CFP, EA

Eventually but no need to do it annually. The client is OK rolling the after-tax portion to a Roth at the plan termination when he retires.

Here's the situation. I'm a fee-only financial advisor who has a few small business owners, mostly individuals, as clients. These clients would benefit greatly from opening Solo 401(k)'s. They want to max out the contribution limit, with the 25% profit sharing, and would like the ability to make after-tax contributions. The custodian I use has a Basic Document but it does not allow after-tax contributions. The custodian said to open a trust and create the plan document myself. Yes I'm a CFP® and EA, and I'm smart enough to know I have no business creating plan documents myself. I see a business opportunity to provide the after-tax options to clients, but cannot do it myself. Can anyone recommend a TPA that can work with an advisor to provide a Solo 401(k) in a cost effective manner? That seems to be the problem. We've attempted to work with a few TPA's but the cost to this just to add the after-tax option, made the client say the heck with this we'll just use the custodians simple basic plan document and forget the after-tax option. Even if you explain the long-term tax benefits, they usually shy away. Again, I see the need for a niche here, but need help.
