Dell Mega-Backdoor Roth

The mega-backdoor Roth strategy offers the ability to save additional after-tax funds. It serves as a powerful tool for tax-efficient wealth accumulation with the benefit of tax-free growth and withdrawals during retirement.


How Dell’s Mega-Backdoor Roth Works

The Mega-Backdoor Roth is a strategy for saving more aggressively and tax-efficiently for retirement by making after-tax contributions to a 401(k) plan and then converting those contributions to a Roth IRA or Roth 401(k).

In 2024, individuals can make $23,000 in pre-tax or Roth 401(k) contributions. Dell matches 6% up to $7,500. Individuals are eligible to save an additional $38,500 in after-tax contributions to their 401(k).

To complete the Mega-Backdoor Roth and avoid a future tax headache, it is critical to convert funds from the after-tax 401(k) to either a Roth 401(k) or Roth IRA.


Tax Consequences from Participating in the Mega-Backdoor Roth

After-tax 401(k) contributions are not taxed when distributed. However, if left untreated, after-tax earnings are taxed as ordinary income when distributed from the 401(k).

So, why would anyone utilize after-tax contributions? After-tax 401(k) contributions grow tax-free after the funds are converted to a Roth IRA or Roth 401(k). Without a Roth conversion, there are generally more tax-efficient ways to save for retirement than by participating in an after-tax 401(k).

How to Execute the Mega-Backdoor Roth for Dell’s 401(k) Plan

Here are steps for executing the mega-backdoor Roth:

  • Determine if the mega-backdoor Roth makes sense within your financial plan.
  • Determine what percentage of your paycheck you want to allocate toward after-tax 401(k) contributions.
  • Update the after-tax percentage online via Fidelity Net Benefits. Processing may take up to one or two pay cycles.
  • Have a process in place for converting funds from after-tax to Roth 401(k).

To properly execute the mega-backdoor Roth, you need a process to move after-tax 401(k) funds to a Roth IRA or Roth 401(k). Here are three ways to accomplish this:

  1. Call the Fidelity Net Benefits desk to make automatic in-plan conversions from after-tax 401(k) to Roth 401(k).
  2. Call the Fidelity Net Benefits desk to convert funds from the after-tax 401(k) to a Roth IRA*.
  3. In some situations, there may be a toggle button when logging in to Fidelity Net Benefits that allows you to select automatic in-plan conversions from after-tax 401(k) to Roth 401(k).

*The after-tax 401(k) to Roth IRA process isn’t automatic and takes much more work to implement.

The phone number for the Fidelity Net Benefits Desk is 1-800-466-2900.


Mega-Backdoor Roth FAQs

When should I consider the mega-backdoor Roth?

The mega-backdoor Roth strategy is best for individuals who have maxed out their pre-tax or Roth 401(k) elective deferral and have additional funds to save tax-efficiently for retirement.

When should I not consider the mega-backdoor Roth?

If you’re not planning to maximize your 401(k) elective deferral or have other financial goals besides retirement that require more immediate attention, then the mega-backdoor Roth may not be appropriate.

Should I contribute to pre-tax or Roth instead of after-tax 401(k)?

In most situations, it is more beneficial to max out pre-tax or Roth contributions before considering after-tax contributions. Pre-tax and Roth 401(k) contributions receive a 6% match up to $7,500, while after-tax contributions receive $0.

Should I invest extra savings in a taxable brokerage account or after-tax 401(k)?

It depends. It’s valuable to have taxable funds for short-term and mid-term goals. Meanwhile, after-tax 401(k) is one of the better tax-advantaged savings options when planning for retirement. Depending on your goals and time horizon, some may find more value by saving in a taxable brokerage account, while others may find more value in saving in the after-tax 401(k).

Should I invest extra savings into Dell’s deferred compensation plan or after-tax 401(k)?

It depends.

It’s unlikely that one would choose to participate in the deferred compensation plan instead of the mega-backdoor Roth strategy. In fact, one could argue for the importance of maxing out many other tax-advantaged accounts before focusing on deferred compensation.

It’s more likely that one would choose to contribute to deferred compensation after it’s clear that they will max out the 401(k). Additionally, to add to the complexity, deferred compensation participation must be selected by December of the previous year, while after-tax 401(k) participation can be toggled on-demand throughout the year.

Deferred compensation can be valuable for minimizing taxes during high income years, but the risks are significant compared to other investment accounts.
