Vanguard has recently announced the details of their Individual 401(k) plan – otherwise known as Solo 401k or Self-Employed 401k. Although you can’t apply yet it seems, many of us passive investors have been waiting for Vanguard to offer this for a long time.
The Vanguard® Individual 401(k) plan is a retirement plan for self-employed individuals. This plan is available only to sole proprietors or partners in business who have no common-law employees. The only other participant allowed in this plan would be a spouse of the business owner if he or she works for the business. Business owners should not establish this plan if they have common-law employees, including their children.
There is some confusion as to whether this includes the sole owners of an S-Corporation, but I’m betting it does as it is a passthrough entity and we are essentially self-employed. Here are some more Vanguard-specific details, along with some comparison with the Fidelity Self-Employed 401(k) which I currently have:
- Seems like you can buy any Vanguard fund with no commissions, and there is “no minimum initial investment required to open most funds” (emphasis mine). It doesn’t seem like you have the option to buy ETFs through their brokerage service. At Fidelity, the Fidelity funds are also free, but I am subject to minimum initial investments. However, I do have the ability to buy any ETF with a $12-$20 commission, as well as buy individual bonds.
- The Vanguard Individual 401(k) will accept three types of employer and employee contribution sources: individual employee salary deferral contributions (pre-tax money), traditional employer contributions (pre-tax money), and Roth salary deferral contributions (post-tax money). Roth is available! Fidelity does not have this.
- Employees can move money between different Vanguard funds by phone or in writing only. This is kind of a pain. I can manage my Fidelity Self-Employed 401(k) online like a regular brokerage account, with limit trades and everything.
- There are no set-up fees charged to the employer for a Vanguard Individual 401(k) plan. Vanguard charges employees a $20 annual account service fee for each mutual fund held in an account within the Vanguard Individual 401(k). If you like to own multipole funds, that can add up quickly! (Note: If at least one participant in a Vanguard Individual 401(k) plan qualifies for Flagship™, Voyager Select™, or Voyager™ Services, the account service fee will be waived for all participants in the plan.) Fidelity has no setup fees, and no annual account fees at all.
- Rollovers are permitted out of the Vanguard Individual 401(k), but not into it. Not sure why this is the case.
This is only a superficial review, but so far I’m not planning to try and open one. It turns out that I am quite happy with my Fidelity Solo 401k, as it provides a lot of flexibility, great customer service, and reasonable costs. Vanguard has a wider array of index funds, but I can also buy the equivalent Vanguard ETFs at Fidelity. If I buy in large enough chunks, the commission is balanced out by the lower annual expense ratios. Besides, if you are at not at least Voyager ($50k in assets), the $20 fee per fund from Vanguard costs as much as two trades anyway.
The main thing going for Vanguard is the Roth option, which I must admit should be very attractive for most people. But for us, our current tax bracket is high enough that I prefer pre-tax contributions.
