Question:

I have the option of investing in a Roth 401(k) or a traditional 401(k). Which do you recommend?

Answer:

The general advice is this:

• If you expect to be in a lower tax bracket in retirement, a traditional 401(k) might be a good choice, as you'll pay less in taxes on your withdrawals.

• If you expect to be in a higher tax bracket in retirement, a Roth 401(k) could be beneficial, as you'll avoid paying taxes on your withdrawals.
