If you’re eligible, it’s possible you could contribute to a 401(k) and an IRA, so it may be helpful to know how they compare from a contribution, withdrawal and tax perspective. Here’s a look at their similarities and differences.
A 401(k) is a type of employer-sponsored retirement plan. Depending on the industry you work in, your workplace retirement plan may be called a 403(b) or 457. Additionally, depending on your workplace plan, you may also have access to a Roth 401(k).
An IRA is an individual retirement account that you open with a financial institution, either a bank or a brokerage firm. Types of IRAs available include traditional IRAs, Roth IRAs and even options for self-employed individuals and small business owners.
There’s a difference in how you fund 401(k)s and IRAs, as well as the investment options available to you.
