There’s no one right way to save for retirement. There are many possible strategies to help maximize your efforts. One way to save more each year is to contribute to a Roth IRA in addition to an employer’s 401(k) plan. Not only is having both a Roth IRA and a 401(k) allowed by the IRS, but having both could also help you build a bigger nest egg. Even if you earn too much for a Roth, you have other options to use these 2 powerful savings tools at the same time.
The Double-Retirement Strategy You Might Be Missing
Hey there, fellow retirement planners! I’ve been deep-diving into the world of retirement accounts lately, and lemme tell ya – there’s some seriously good news if you’re self-employed or have a side hustle. Yes, you can absolutely have both a Roth IRA and a Solo 401(k) at the same time! This powerful combo could be your ticket to a much more comfortable retirement.
As a self-employed person myself, I was thrilled when I discovered this little-known strategy. The ability to contribute to both accounts gives us entrepreneurs and freelancers a massive advantage when planning for our golden years.
Why You Should Consider This Power Combo
Before we dive into the nitty-gritty. let’s get straight to the point having both a Roth IRA and a Solo 401(k) can significantly boost your retirement savings because
- You get separate contribution limits for each account
- You can diversify your tax advantages (tax-free growth vs. tax deductions now)
- You gain more control and flexibility over your retirement planning
- You can potentially save WAY more per year than with just one account
Now, let’s break down how these accounts work together and why this combo is such a smart move.
Understanding the Basics: Roth IRA vs. Solo 401(k)
Before we go further let’s quickly review what these accounts actually are
Roth IRA:
- Funded with after-tax dollars
- Grows tax-free
- Tax-free withdrawals in retirement (if you follow the rules)
- 2024 contribution limit: $7,000 ($8,000 if you’re 50+)
- 2025 contribution limit: $7,000 ($8,000 if you’re 50+)
- Income limits apply for eligibility
Solo 401(k) (also called Individual 401(k)):
- For self-employed individuals with no employees (except spouse)
- Can make both employer and employee contributions
- 2024 contribution limit: Up to $23,000 as employee + up to 25% of compensation as employer, with total combined limit of $69,000 ($76,500 if 50+)
- 2025 contribution limit: Up to $23,500 as employee + up to 25% of compensation as employer
- No income limits for participation
The Beautiful Truth: Separate Contribution Limits
Here’s where things get exciting. The contribution limits for each account are completely separate from each other. This means contributing to one doesn’t reduce how much you can put in the other!
This is hugely different from, say, having multiple IRAs, where your total contributions across all IRA accounts can’t exceed the annual limit.
Let’s look at a real-world example:
Example: Sarah, a 45-year-old freelance graphic designer, makes $100,000 in net self-employment income.
- She can contribute $7,000 to her Roth IRA (2024 limit)
- As “employee” of her Solo 401(k), she can contribute up to $23,000
- As “employer,” she can contribute roughly 20% of her net income after deducting self-employment taxes (approximately $18,587)
- Total retirement savings potential: $48,587 for 2024!
That’s nearly half her income going into tax-advantaged retirement accounts! Try doing that with just a single account type.
Roth Solo 401(k): Another Option to Consider
It’s worth mentioning that Solo 401(k) plans can often include a Roth component, similar to how many employer 401(k) plans now offer a Roth option. This means you actually have three potential combinations:
- Traditional Solo 401(k) + Roth IRA
- Roth Solo 401(k) + Roth IRA
- Split your Solo 401(k) between traditional and Roth + Roth IRA
This flexibility lets you really customize your tax strategy based on your current situation and future expectations.
Income Limits: The Potential Roadblock
While there are no income limits for Solo 401(k) participation, Roth IRAs do have income eligibility thresholds. For 2024:
- Single filers: Phase-out starts at $146,000 and you’re ineligible at $161,000
- Married filing jointly: Phase-out starts at $230,000 and you’re ineligible at $240,000
For 2025, these limits increase slightly:
- Single filers: Phase-out starts at $150,000 and you’re ineligible at $165,000
- Married filing jointly: Phase-out starts at $236,000 and you’re ineligible at $246,000
If your income is too high, don’t worry! You might still be able to use the “backdoor Roth” strategy by contributing to a traditional IRA and then converting it to a Roth IRA.
Setting Up Your Accounts: Practical Steps
If you’re convinced that the Roth IRA + Solo 401(k) combo is right for you, here’s how to get started:
Step 1: Confirm Your Eligibility
- Verify you have self-employment income (even from a side gig)
- Check that you meet Roth IRA income requirements
- Ensure you have no full-time employees (besides a spouse)
Step 2: Open Your Accounts
- For Solo 401(k): Choose a provider (Fidelity, Vanguard, etc.) and complete their application
- For Roth IRA: Open an account with any major brokerage
Step 3: Create a Contribution Strategy
- Decide how much to contribute to each account
- Determine if you’ll make employee and employer contributions to your Solo 401(k)
- Set up automatic contributions if possible
Step 4: Choose Your Investments
- Select investments within each account based on your risk tolerance
- Consider diversifying across both accounts
Tax Planning Considerations
One of the best parts about having both accounts is the tax diversification benefits. Here’s how to think about it:
Current Tax Situation:
- In high tax bracket now? Consider traditional (pre-tax) Solo 401(k) contributions to reduce current taxes
- In lower tax bracket? Consider Roth options for both accounts
Future Tax Expectations:
- Expect higher tax rates in retirement? Prioritize Roth contributions
- Expect lower tax rates in retirement? Mix of traditional and Roth might be ideal
Remember, having both pre-tax and Roth accounts gives you flexibility to manage your taxable income in retirement!
Practical Tips for Maximizing This Strategy
Based on my own experience and research, here are some practical tips:
-
Prioritize employer match first – If you have a day job with a 401(k) match in addition to self-employment income, always get the full match before funding other accounts
-
Consider front-loading – If your cash flow allows, consider making your Roth IRA contribution early in the year to maximize tax-free growth
-
Be careful with deadlines – Roth IRA contributions can be made until tax day of the following year, but Solo 401(k) employee contributions generally must be made by December 31
-
Keep good records – With multiple accounts, tracking your contributions becomes more important
-
Consult a tax pro – The interaction between these accounts can get complex, especially when calculating your maximum Solo 401(k) contribution
Real-Life Example: How I Use Both Accounts
I personally use both these accounts for my retirement planning. Here’s my approach:
I have a content creation business that generates about $120,000 in net income annually. I max out my Roth IRA first ($7,000 for 2024), then make both employee and employer contributions to my Solo 401(k).
For my Solo 401(k), I split my contributions between traditional (to lower my current tax bill) and Roth (for tax-free growth). This gives me tax diversity and more options in retirement.
Last year, I was able to shelter nearly $45,000 from either current or future taxation – that’s money that’s either reducing my taxes now or growing completely tax-free for later!
Common Questions About Having Both Accounts
Q: Will contributing to both accounts create any tax complications?
A: Not really! The IRS treats them as separate accounts with separate limits. Just keep good records.
Q: Can I roll my Solo 401(k) into my Roth IRA later?
A: Yes, but a rollover from a traditional Solo 401(k) to a Roth IRA would be a taxable event. Roth 401(k) funds can roll into a Roth IRA tax-free.
Q: What if my income varies year to year?
A: That’s actually where this strategy shines! In high-income years, you can max out both accounts. In lower-income years, you might focus just on the Roth IRA.
Q: Do I need to file any special paperwork with the IRS?
A: Solo 401(k) plans need to file Form 5500-EZ once plan assets exceed $250,000. No special forms needed just for having both accounts.
Q: Can my spouse also do this strategy?
A: Absolutely! If your spouse is also involved in your business, they can have their own Solo 401(k) and Roth IRA too.
The Bottom Line: Double Your Retirement Potential
Having both a Roth IRA and a Solo 401(k) is completely allowed and is one of the most powerful retirement saving strategies available to self-employed individuals and small business owners. The separate contribution limits let you save significantly more than you could with either account alone.
This combo gives you:
- Higher total contribution limits
- Tax diversification benefits
- More investment options
- Greater flexibility in retirement
For self-employed folks like us, retirement planning falls entirely on our shoulders – no corporate pension or HR department to help out. Taking advantage of every available tool is just smart planning, and the Roth IRA + Solo 401(k) combo is one of the best tools in our toolkit.
Have you started using this powerful combo yet? If not, what’s holding you back? Remember, the sooner you start, the more time your money has to grow. And with the tax advantages of these accounts, that growth can be pretty impressive over time!
Final Thoughts
Remember that retirement planning is personal, and what works for one person might not be right for another. Consider consulting with a financial advisor who specializes in working with self-employed professionals to create a customized strategy for your situation.
Now go forth and save for that awesome retirement you deserve!
Benefits of having a Roth IRA and a 401(k)
From increasing your annual retirement savings to potential tax breaks—both today and in retirement—Roth IRAs and 401(k)s could deliver on multiple levels when used together.
- A substantial savings boost While the $23,500 401(k) contribution limit for 2025 for employees under 50 is nothing to sneeze at—its up $500 from 2024)—adding a Roth IRA (or a traditional IRA, for that matter) into the mix kicks things up a notch, allowing you to save an additional $7,000 on top of your 401(k) contributions. Catch-up contributions allow those 50 or older to invest even more. For 2024, those 50 or older can contribute up to an extra $1,000 to their Roth IRA and an extra $7,500 to their 401(k). Those limits stay the same for 2025 if youre age 50 to 59 or 64 or older. But if youre age 60 to 63, you may be eligible to contribute up to $11,250 more to your 401(k) if your employers plan allows it. In other words, an individual age 60 to 63 can contribute up to $34,750 to their 401(k) in 2025. Note: Stated contribution limits are for eligible individuals, which means that each spouse in a married couple may be able to contribute up to the maximums shown.
- Access to money in a pinch before retirement Unlike a traditional IRA or a traditional 401(k), the Roth IRA is one of the few tax-advantaged accounts that allows you to withdraw the money you’ve contributed at any time for any reason without paying taxes or penalties. This means you can access some of your retirement savings in an emergency without adding to debt or selling assets in a taxable account, which could have tax implications. Though it’s generally best to build up emergency savings with $1,000 or more separately from retirement savings, knowing you can access those Roth IRA contributions if you really needed them could set your mind at ease. Your Roth IRA could serve as a source of backup emergency savings. Roth 401(k)s dont allow for withdrawals of just contributions. If taking a Roth 401(k) withdrawal, a portion of the withdrawal may be earnings.
- Present and future tax benefits Investing in a Roth IRA and a 401(k) offers potential tax advantages now and in the future. While contributions to a Roth IRA aren’t tax deductible, earnings grow tax-deferred while you save, and qualified withdrawals during retirement are generally tax-free.3 With a traditional 401(k), it’s reversed: Pre-tax contributions today reduce your taxable income which can, in turn, reduce that year’s tax bill. Any investment growth on pre-tax contributions in a traditional 401(k) is tax-deferred, and in retirement your withdrawals are taxed at your current income tax rate, except for any after-tax money you might have contributed. With the ability to choose between tax-free and taxable withdrawals, you can potentially save on taxes by managing your taxable income in retirement. For instance, if you choose to work part-time and still have taxable income, taking qualified withdrawals from your Roth IRA won’t bump you to a new tax bracket like taxable withdrawals from a 401(k) might. If you paired your 401(k) with a traditional IRA, withdrawals from both of those accounts would be taxable and may increase the amount of income taxes you pay in retirement.
- Lower required minimum distributions (RMDs) Another difference between a 401(k) or traditional IRA and a Roth IRA is that you’re not required to withdraw money from a Roth IRA after a certain age, whereas you must start taking RMDs from most traditional 401(k) plans and traditional IRAs after age 73. This gives you more flexibility in retirement to use the money in your Roth IRA when it best suits you. This also means you could choose to leave extra money in your Roth IRA—tax-free—to your loved ones after you’re gone. Just remember, inherited Roth IRAs have required minimum distributions, which will affect your heirs.
What’s the difference between a Roth IRA and a 401(k)?
The biggest difference between a Roth IRA and a 401(k) is that a 401(k) is offered by (and opened through) your employer, while a Roth IRA can be opened on your own through a financial services custodian such as Fidelity. When you contribute to a traditional 401(k), typically the money is taken out of your paycheck before you pay taxes. This reduces your taxable income for the year (though some plans do allow you to make after-tax traditional 401(k) contributions). Roth IRA contributions, on the other hand, are made with after-tax dollars, so they will not reduce your taxable income. Many employers also offer a match on 401(k) contributions up to a certain percentage of your salary—say, 3% or more—which can boost the amount that goes into your account each year. That is not available for Roth IRAs, as they are not connected to your employer.
In both account types, you can invest your contributions in securities including mutual funds, and those investments have the potential to grow tax-deferred while you save.1 With a 401(k), you’ll typically pay income taxes once you begin making withdrawals—though not on any after-tax contributions—and if you withdraw before age 59½ you may also pay a penalty. 401k plans do have a benefit over IRAs for early withdrawals, however. You can withdraw penalty free if you withdraw money from the plan if you leave your employer sponsoring the plan in or after the year you turn 55. With a Roth IRA, you can withdraw as much as you’ve contributed—but not any investment earnings—at any time for any reason without paying taxes or penalties. If you’ve had the account open for at least 5 years and you’re over 59½ years old or you meet certain other qualifications, then you may be able to withdraw investment earnings tax-free and penalty-free.2
Some employers offer a second type of 401(k) called a Roth 401(k), which is a kind of hybrid between a Roth IRA and a 401(k) with some rules from each kind of plan. In a Roth 401(k), you invest after-tax money today and dont pay income taxes on your withdrawals in retirement. Learn more about contributing to a Roth vs. traditional 401(k).
