Should I Open an IRA If I Have a 401k?

It is common for individuals to consider whether to establish an Individual Retirement Account (IRA) when they are already contributing to a 401(k) through their employer. Both account types serve as powerful vehicles for retirement savings, each with distinct features and benefits. The decision to utilize both often depends on an individual’s financial situation, long-term goals, and investment preferences.

Understanding Your Retirement Accounts

A 401(k) plan is an employer-sponsored retirement savings account that allows employees to contribute a portion of their pre-tax salary directly from their paycheck. Contributions made to a traditional 401(k) are typically tax-deductible in the year they are made, reducing an individual’s current taxable income. The money within the account grows on a tax-deferred basis, meaning no taxes are paid on investment gains until funds are withdrawn in retirement. For 2025, the annual contribution limit for employees participating in 401(k) plans is $23,500, with an additional catch-up contribution of $7,500 allowed for those aged 50 and over.

A Traditional IRA is an individual retirement arrangement that allows pre-tax contributions to grow tax-deferred until retirement, similar to a traditional 401(k). Contributions may be tax-deductible, depending on an individual’s income and whether they are covered by a workplace retirement plan. Withdrawals in retirement are taxed as ordinary income, reflecting the tax deferral benefits received during the accumulation phase. The annual contribution limit for a Traditional IRA in 2025 is $7,000, with an additional catch-up contribution of $1,000 permitted for individuals aged 50 and older.

A Roth IRA stands apart by operating with after-tax contributions, meaning contributions are not tax-deductible in the year they are made. The significant advantage of a Roth IRA is that qualified withdrawals in retirement, including all earnings, are entirely tax-free. This tax-free growth and withdrawal feature can be particularly appealing for those who anticipate being in a higher tax bracket during retirement. The 2025 annual contribution limit for a Roth IRA is also $7,000, with an additional $1,000 catch-up contribution for individuals aged 50 and over.

Advantages of an IRA Alongside a 401k

Opening an IRA even when already contributing to a 401(k) can provide several distinct advantages, primarily centered around increased investment flexibility and potential for greater savings. A significant benefit of an IRA is the typically broader range of investment options available compared to most employer-sponsored 401(k) plans. While 401(k)s often limit choices to a curated selection of mutual funds, an IRA can offer access to individual stocks, bonds, exchange-traded funds (ETFs), and a wider array of mutual funds from various providers. This expanded selection allows for greater customization of an investment portfolio to align with specific financial goals and risk tolerance.

Another advantage can be the potential for lower administrative and investment fees associated with self-directed IRAs. Some employer-sponsored 401(k) plans may carry higher administrative costs or offer investment options with higher expense ratios. By contrast, many brokerage firms offer IRAs with competitive fee structures, potentially allowing individuals to retain a larger portion of their investment returns over time. This cost efficiency can significantly impact the long-term growth of retirement savings.

An IRA provides individuals with greater control and flexibility over their retirement assets. This includes the ability to choose specific investments, consolidate accounts from previous employers, and manage asset allocation strategies more actively. The increased control allows for a more personalized approach to retirement planning, enabling adjustments based on market conditions or changes in personal financial circumstances.

An IRA also serves as an important vehicle for supplemental savings, allowing individuals to save beyond the annual contribution limits imposed on 401(k) plans. For those who consistently max out their 401(k) contributions, an IRA offers an additional avenue to accumulate more retirement funds. This additional savings capacity is particularly beneficial for individuals aiming for an earlier retirement or a more robust financial cushion in their later years.

Access to the unique benefits of a Roth IRA is another compelling reason to open an IRA alongside a 401(k), especially if a Roth 401(k) option is not available or preferred. The promise of tax-free withdrawals in retirement can be a powerful financial planning tool, providing certainty regarding future tax liabilities on retirement income. For high-income earners who exceed the direct Roth IRA contribution limits, a “backdoor Roth” strategy allows them to contribute to a Traditional IRA and then convert those funds to a Roth IRA, bypassing the income restrictions.

Key Considerations for Combined Savings

When managing both a 401(k) and an IRA, understanding the deductibility rules for Traditional IRA contributions is important. If an individual is covered by a workplace retirement plan, such as a 401(k), the deductibility of their Traditional IRA contributions is phased out based on their modified adjusted gross income (MAGI). For 2025, single filers covered by a workplace plan may fully deduct their contributions if their MAGI is $79,000 or less, with deductibility phasing out entirely between $79,001 and $89,000. For married couples filing jointly, where the spouse making the IRA contribution is covered by a workplace plan, the full deduction is available if their MAGI is $126,000 or less, phasing out between $126,001 and $146,000.

Roth IRA contributions also have income limitations that can affect eligibility for direct contributions. For 2025, the ability to contribute directly to a Roth IRA begins to phase out for single filers with a MAGI between $150,000 and $165,000. For married couples filing jointly, the phase-out range for Roth IRA contributions is between $236,000 and $246,000 of MAGI. Individuals whose MAGI exceeds these upper limits cannot make direct contributions to a Roth IRA.

Coordinating contributions between a 401(k) and an IRA requires careful consideration of financial priorities. It is generally advisable to first contribute enough to a 401(k) to receive any available employer match, as this represents a 100% immediate return on investment. After securing the employer match, individuals might then prioritize contributing to an IRA, particularly a Roth IRA, for its tax-free growth and withdrawal benefits, or a Traditional IRA for its potential tax deduction and broader investment choices. Once the IRA is funded, individuals can then return to maximizing their 401(k) contributions.

Utilizing both pre-tax accounts, such as a traditional 401(k) or Traditional IRA, and after-tax accounts, like a Roth IRA, creates a strategy known as tax diversification. This approach provides flexibility in retirement by offering different types of income, some taxable and some tax-free. Having a mix of these accounts allows retirees to strategically draw funds based on their tax situation in any given year, potentially minimizing their overall tax burden during retirement. This flexibility can be particularly beneficial as future tax laws and personal circumstances are uncertain.

Ultimately, the decision to open an IRA alongside a 401(k) is highly personal and should align with an individual’s unique financial situation and retirement objectives. Factors such as income level, access to an employer match, desired investment control, and expectations about future tax rates all play a role in determining the most effective savings strategy. Evaluating these elements helps in creating a comprehensive retirement plan that maximizes savings and optimizes tax efficiency.
