There are many variables to consider when choosing a Roth individual retirement account (Roth IRA) or a 401(k). Each type of account provides an opportunity for savings to grow tax free. Roth IRAs do not provide tax advantages when you make a deposit, but you can withdraw tax free during retirement. The reverse is true for 401(k)s. These types of accounts involve contributing a portion of your paycheck into a 401(k) prior to income tax deductions. In terms of contribution limits, Roth IRAs are typically lower than 401(k)s. Additionally, 401(k)s allow employers to make matching contributions. On the flip side, 401k(s) often have higher fees, minimum distributions, and fewer investment options.
