When deciding on contributions to your 401(k) plan, you might wonder whether it’s better to choose pre-tax (traditional) contributions or after-tax (Roth) contributions. The best choice depends on your current and anticipated future tax circumstances, as well as estate planning goals.
Traditional vs. Roth 401(k)s
The main difference between a traditional and a Roth 401(k) plan is how they are taxed. With a traditional 401(k), contributions are made with pre-tax dollars, which means you get a tax deduction when you contribute. Your money grows tax-deferred, but you’ll pay taxes on both your contributions and earnings when you withdraw them.
In contrast, Roth 401(k) contributions are made with after-tax dollars, so you don’t get a tax break upfront but qualified withdrawals, including contributions and earnings, are tax-free. Plus you can contribute to a Roth 401(k) plan no matter how hight your income is.
For 2024, the salary deferral limits for both traditional and Roth 401(k) plans are the same: $23,000, plus an additional $7,500 if you’re 50 or older by the end of the year. Combined employee and employer contributions can go up to $69,000, or $76,500 if you’re 50 or older.
The rules for taking distributions from traditional and Roth 401(k)s are similar. You may take penalty-free withdrawals when you reach age 59½, or if you die or become disabled (with some exceptions). For Roth 401(k)s, the account must be open for at least five years to take withdrawals.
One key difference is that traditional 401(k) accounts require a minimum distribution (RMD) at age 73 (or age 75 starting in 2032). Roth 401(k) accounts do not have RMDs starting in 2024.
From a tax perspective, with a Roth 401(k) means you pay taxes now, while a traditional 401(k) defers taxes until you withdraw the funds. Mathematically speaking, that means the best choice depends on whether you expect to be in a higher or lower tax bracket in retirement.
If you’re a high earner and expect a lower bracket when you retire, a traditional 401(k) might be more beneficial. On the other hand, if you expect to be in a higher tax bracket later (perhaps due to higher income or potential tax increases), a Roth 401(k) might be a better choice.
Estate planning factors
Tax implications during your lifetime aren’t the only thing to think about. Estate planning factors are important too. Roth 401(k)s, with their elimination of RMDs, can be a powerful estate planning tool. If you don’t need the funds for living expenses, you can let the grow tax-free for as long as you want. And if the account is at least five years old, your heirs can withdraw the money tax-free.
On the other hand, a traditional 401(k) requires you to withdraw funds according to RMD rules, which might reduce the amount left for you heirs. Plus, their withdrawals will be taxable.
