Ask Alight: What is a Roth 401(k) and why do I need one?

How will your taxes in retirement compare to what they are today? A Roth 401(k) may provide some much-needed relief.

Roth 401(k) vs. Traditional 401(k)

Contributions to a 401(k) typically reduce your taxable income now, but you pay taxes on the money as you make withdrawals to cover your expenses in retirement. For Roth 401(k)s, it’s just the opposite. Your tax burden is higher now, but your retirement income is tax free¹.  Everything else—the investment options, the match you get from your employer, the loan and withdrawal options—are the same as the rest of your 401(k).  And you can contribute to both at the same time.

How much can you save to a Roth 401(k)?

Each year, the IRS sets maximum amounts that can be contributed to 401(k) plans. These amounts apply to the combined total of Roth 401(k) and pre-tax 401(k) contributions. In 2023, the annual contribution is capped at $22,500 for people under age 50. Those over 50 are usually eligible for catch-up contributions, bringing their total to $30,000. So, for example, if you’re under 50, and you want to contribute $10,000 to your pre-tax 401(k), the most you can contribute to your Roth 401(k) would be $12,500.

For 2023:

What is a Roth 401(k) conversion?

Some 401(k) plans allow you to convert your pre-tax 401(k) balance to a Roth 401(k). The catch? Any amount that is converted now will be added to your taxable income this year. Therefore, any dreams of not paying taxes in your golden years could be seriously offset by your tax bill next April 15^th.

When is saving to a Roth 401(k) a good idea²?

If your current tax rate and your retirement tax rate are likely to be the same, it won’t really matter if you save on a pre-tax basis or a Roth basis. However, if you expect that your taxes in retirement will be higher than what they are now, Roth 401(k) contributions are generally a good idea. Conversely, if your taxes in retirement are expected to be less, then pre-tax contributions are probably better.

Deciding to contribute to a Roth 401(k) may seem like a simple question of, “Do I want to pay more taxes now or later?” However, there are many details to consider. Before starting to save to a Roth 401(k), be sure to read up on the specifics for your employer’s 401(k) and talk to a professional who understands your specific financial situation and goals.
