Can you contribute to both a traditional 401k and a Roth 401k?

Yes, you can contribute to both a traditional 401(k) and a Roth 401(k) as long as your employer offers both options. Traditional 401(k) contributions are made with pre-tax dollars, while Roth 401(k) contributions are made with after-tax dollars. Each type of account has its own tax advantages and considerations for retirement savings.
