Understanding the 401(k) and IRA
A 401(k) is an employer-sponsored retirement plan where you contribute pre-tax income (or after-tax if using a Roth 401(k)). Many employers offer matching contributions, which is essentially “free money” toward your retirement.
An IRA (Individual Retirement Account) is opened on your own through a bank, broker, or investment company. It also offers tax advantages but is independent of your employer.
Contribution Limits for 2025
| Account Type | Annual Contribution Limit | Catch-Up Contribution (50+) |

Tax Rules
401(k)
- Traditional: Contributions are pre-tax; withdrawals taxed as income in retirement.
- Roth: Contributions are after-tax; withdrawals in retirement are tax-free (if conditions are met).
- Required Minimum Distributions (RMDs) start at age 73 (unless still working and plan allows deferral).
IRA
- Traditional: Pre-tax contributions if eligible; withdrawals taxed in retirement.
- Roth: After-tax contributions; qualified withdrawals tax-free.
- RMDs apply to Traditional IRAs starting at age 73; Roth IRAs have no RMDs during the owner’s lifetime.

Which is Better at Different Life Stages?
Early Career (20s–30s)
If your employer offers a 401(k) match, contribute enough to get the full match—it’s free money. Then consider an IRA to access a wider range of investments.
Mid-Career (40s–50s)
Max out your 401(k) if you can, especially if you’re in a higher tax bracket now and expect to be in a lower bracket at retirement. Add IRA savings for more flexibility.
Pre-Retirement (50s–60s)
Take advantage of catch-up contributions in both accounts. Diversify between pre-tax and Roth options to manage taxes in retirement.
Combining a 401(k) and an IRA
Many people use both. A 401(k) can capture employer matches and allow high contributions, while an IRA offers more investment control and Roth benefits.
FAQs
Q1: Can I have both a 401(k) and an IRA?
Yes, you can contribute to both in the same year, but IRA contribution deductibility may be affected by your income if you also have a 401(k).
Q2: Which is better for tax savings?
If you want upfront tax savings, a Traditional 401(k) or IRA works. For tax-free withdrawals later, consider a Roth version.
Q3: What if my employer doesn’t offer a 401(k)?
Open an IRA with a bank or brokerage. You can also explore a Solo 401(k) if you’re self-employed.
Conclusion
Both a 401(k) and an IRA have their place in a solid retirement planning strategy. A 401(k) shines for higher contribution limits and employer matches, while an IRA offers more investment freedom and Roth benefits. The best choice often isn’t one or the other—it’s using both together.
