Now, let's say that investment triples in another five years, giving you an account value of $8,100. You'd owe another $810 in capital gains tax on your $5,400 in profits, giving you an ending value of $7,290.
Meanwhile, the same investments in an IRA would be worth more at the end. You would have been able to reinvest the full $3,000 in proceeds from the first, and the second would have grown to $9,000. And no capital gains tax would be due if you left the money in the account.
Benefits of an IRA vs. a 401(k)
A 401(k) is another type of tax-advantaged retirement account. IRAs have a couple of notable advantages over 401(k) plans:
- IRAs allow you to invest in stocks, bonds, mutual funds, or ETFs -- anything the broker offers. 401(k)s limit you to a small selection of investments chosen by the plan administrator.
- IRAs have some penalty-free early-withdrawal exceptions that don't apply to 401(k)s, including qualified higher education expenses and up to $10,000 toward a first-home purchase.
Contributing to a 401(k) could still be worthwhile. Many employers offer a 401(k) match, which is about as close as it gets to free money. Remember that you don't need to choose one or the other. You can contribute to an IRA and a 401(k) to get the benefits of both.
