This guide conducts a comprehensive analysis of the Fidelity Solo 401k plan, also known as the Fidelity Self-Employed 401k plan, the Fidelity Self-Directed 401k, Fidelity Individual 401k, or the Solo 401k Fidelity plan.

Self-employment, small businesses, and freelancing are always close to my heart. Although I do have my day job as a business consultant in an engineering firm, my heart and soul lie in creating my own small business. This website is one endeavor in that direction. However, to sustain a small business, its taxes and finances need to be in place.

One topic of considerable importance is the retirement of self-employed and freelance individuals. As I have mentioned in my earlier posts, a solo 401k is an efficient plan to stash retirement wealth for self employed individuals.

A solo 401k apart from tax benefits, allows you to stash the maximum contributions in your retirement plan. This is because you can contribute both as an employee and as an employer in a solo 401k (read solo 401k contribution limits).

But often, we get stuck on the decision of which provider to choose for a solo 401(k). One trusted and dependable brand for a solo 401(k) is Fidelity.

Fidelity stands out as one such trusted partner, boasting a legacy of over 75 years, catering to more than 43 million individual investors, and managing assets totaling $11.7 trillion (as of June 30, 2023).

In this guide, we will take a close look at the Fidelity Solo 401(k) plan from all angles. This will include how to set up a Fidelity Solo 401(k) account, available investment options, eligibility for the plan, the user experience of the Fidelity plan, Roth option availability, participant loan availability, fees, and rollover

Fidelity Roth Solo 401k 

When I checked with Fidelity, they confirmed that at this point, they do not offer a Roth option for solo 401k retirement accounts.

Currently, they only offer traditional IRA (pre-tax contributions).

Hence, a Fidelity Solo Roth 401k or Fidelity Roth Solo 401k or Fidelity Solo 401k Roth does not exist till now at the time of writing this guide.

However, if you choose a self-directed solo 401k provider such as My Solo 401k and open a brokerage account with Fidelity, you can take advantage of the Roth option as well. In this scenario, you can also explore other benefits like investing in alternative assets (such as real estate, tax liens, cryptocurrencies, etc.), having access to participant loans, and more.

Fidelity Solo 401k rollover

If you already have a retirement savings account like SEP, or employer 401k, it can be rolled over or transferred to the Fidelity Solo 401k.

It is suggested you consult your financial advisor or a Fidelity consultant at 800-544-5373 to get help.

Rollover is allowed for the following:

  • Profit Sharing, Money Purchase, and 401(k) plans
  • SEP IRAs and SARSEPs
  • SIMPLE IRA accounts after two years of SIMPLE participation
  • 403(b) and governmental 457(b) plans
  • Traditional IRAs

Fidelity Solo 401k loan

The Fidelity solo 401k does not entitle you to take a loan against the plan.

As mentioned above, if you choose a self-directed solo 401k provider such as My Solo 401k and open a brokerage account with Fidelity, you can take advantage of the Roth option as well. In this scenario, you can also explore other benefits like investing in alternative assets (such as real estate, tax liens, cryptocurrencies, etc.), having access to participant loans, and more.

Please note that the Fidelity 401k plan (employer-sponsored) entitles you to take a loan against your plan. 

Just to state, a loan is a better idea, than withdrawing some amount out of your 401k savings, to address your urgent needs.

A loan does not remove the amount from your 401k savings. In some time, you pay back the loan amount with interest to yourself, which is added to your 401k savings.

However, if you withdraw funds, it is permanently removed from the 401k savings. Besides, tax is also levied on the funds withdrawn. Furthermore, a 10% penalty is also charged in most cases (other than few exceptions).

Fidelity Solo 401k mega backdoor Roth

The question is, does Fidelity solo 401k plan allow mega backdoor Roth?

The answer is “No”. The Fidelity solo 401k plan does not allow a mega backdoor Roth option, where you can make after-tax contributions and convert your plan to a Roth IRA or Roth 401k.

In order to employ the mega backdoor Roth strategy for more savings, you can open an account with My Solo 401k.

My Solo 401k is a self-directed solo 401k provider, which will open your account with Fidelity as your brokerage account. 

Now here, you can make a mega backdoor Roth contribution.

The mega backdoor Roth is a strategy to make larger contributions in your retirement plan. It is for those people who earn too much to contribute to a Roth plan.

For instance a single taxpayer who earns $153,000 or more, or a married filing jointly taxpayer who earns $228,000 or more, are not eligible to contribute into a Roth IRA or Roth 401k plan in 2023. 

For these categories of taxpayers, the mega backdoor Roth is a strategy to make Roth contributions.
