Does 401k match make sense for a small business owner with S corp?
Title: Does 401k match make sense for a small business owner with S corp? 1 I'm the sole owner and employee of my S corporation. I've got a solo 401k plan set up and my annual salary exceeds the employee contribution limit ($23,000 for 2025). I'm trying to figure out the most tax-efficient strategy for retirement savings. My main goals are minimizing taxes while maximizing retirement savings. I'm wondering if it makes financial sense to utilize the employer matching option on my 401k to contribute additional funds beyond the employee limit? Or would I be better off just maxing out the employee contribution portion and then putting any extra retirement savings into a regular taxable brokerage account? I've been going back and forth on this and could really use some advice from others who might have been in a similar situation.

8 As someone who's worked with small business owners on retirement planning for years, I can tell you that employer contributions to your solo 401k almost always make more sense than using a taxable brokerage account if tax minimization is your goal. Since you're both the employer and employee, you can make employer contributions up to 25% of your compensation (subject to overall limits). These contributions are tax-deductible business expenses that reduce your business income, which means less pass-through income on your personal return. Meanwhile, money in a taxable brokerage account provides no immediate tax benefit and you'll pay taxes on dividends and capital gains. The total combined limit for solo 401k contributions (employee + employer) is $69,000 for 2025 ($76,500 if you're 50+). Maximizing both portions will almost always be more tax-efficient than using a taxable brokerage for retirement savings.

•4 Thanks for this info. I'm in a similar situation but have a question - doesn't making employer contributions just shift where I'm being taxed? Like if my S-corp makes the contribution, that's less money distributed to me as profit, so aren't I just trading one form of tax for another? Or am I missing something about how this works?

•8 The employer contribution reduces your business's taxable income, which is more favorable than taking that money as personal income first. When your S-corp makes a contribution, it's deducted as a business expense before profits pass through to your personal return. If you took that same money as a distribution instead, you'd pay personal income tax on it first, then invest what's left in your brokerage account. Additionally, any earnings in your 401k grow tax-deferred, while brokerage investments face annual taxation on dividends and realized gains. The tax savings compound significantly over time.

12 I was in basically the exact same situation last year. I spent hours researching tax strategies for my single-member S-corp and discovered this amazing tool at https://taxr.ai that literally saved me thousands in taxes. It analyzed my business structure and created a personalized retirement contribution strategy. The tool showed me that for S-corps, making employer contributions to my solo 401k was WAY more tax-efficient than using a taxable account. It also helped me understand how to balance my salary vs. distributions to optimize both 401k contributions and self-employment taxes. You can run different scenarios to see exactly how much you'll save with different contribution strategies. Seriously, check it out!

•7 How exactly does this work with calculating the right balance between salary and distributions? I'm always worried about taking too little salary and getting in trouble with the IRS but also don't want to pay more in SE taxes than necessary.

•13 Sounds interesting but these tools always seem to just give generic advice that you can find anywhere. Does it actually take into account specific state tax situations? I'm in California which complicates everything tax-wise.

•12 The tool has a specific feature that helps calculate a reasonable salary based on your industry, location, and business profits. It shows you different salary scenarios and how they impact both your tax situation and maximum allowable 401k contributions. This helps stay compliant with the IRS's "reasonable compensation" requirements while optimizing your tax position. It definitely handles state-specific tax situations including California. That's actually one of its strengths - it factors in both federal and state tax implications when making recommendations. California's high income tax rates actually make retirement contributions even more valuable, and the tool quantifies exactly how much you'll save at both levels.

13 Just wanted to update - I was skeptical about taxr.ai but decided to try it after struggling with my S-corp tax planning. Holy crap, it was eye-opening! The analysis showed me that by restructuring my compensation and maxing out both employee AND employer 401k contributions, I could save over $14,000 in combined taxes compared to my previous approach. What really surprised me was seeing how the math works out over time. The tax-deferred growth in the 401k absolutely demolishes what you'd end up with in a taxable account, even accounting for future tax rates. The tool even showed me how to time my contributions throughout the year to maximize my cash flow. Definitely worth checking out if you're trying to optimize an S-corp retirement strategy.

15 After reading this thread, I wanted to share something that helped me when I was in a similar situation trying to figure out my S-corp retirement strategy. I was spending HOURS on hold trying to get someone at the IRS to explain how employer contributions work for S-corps, and getting nowhere. A friend recommended https://claimyr.com and showed me this demo: https://youtu.be/_kiP6q8DX5c. It's a service that navigates the IRS phone system for you and calls you back when an actual human agent is on the line. I was honestly shocked when I got a call back with a knowledgeable IRS rep who walked me through exactly how to handle my situation with documentation requirements for my solo 401k. The agent confirmed that employer contributions are almost always more tax-efficient and explained the exact forms and records I needed to keep for substantiating my contributions. Saved me hours of frustration and gave me confidence my retirement strategy was IRS-approved.

•21 Wait, are you serious? This actually works? I've literally spent cumulative days of my life on hold with the IRS and usually end up giving up. How long did it take for them to get someone on the line for you?

•9 This sounds too good to be true tbh. Why would the IRS pick up for them but not regular people? Are they using some kind of special access system or something? Seems fishy.

•15 Yes, it actually works! For me it took about 1 hour and 20 minutes before I got the callback - which beats the 3-4 hours I usually spend on hold. I was able to go about my day instead of being stuck with a phone to my ear. They don't have special access - they just have automated systems that wait on hold for you. The IRS treats their call the same as anyone else's, but instead of YOU waiting on hold, their system does it and only connects you when a human agent is actually on the line. Nothing fishy about it - they're just solving the hold time problem with technology.

9 I can't believe I'm saying this, but I tried that Claimyr service after reading about it here because I was desperate for answers about my S-corp retirement options. I was 100% convinced it was going to be a waste of time. I was WRONG. Got a callback in about 2 hours with an actual IRS tax specialist on the line. The agent walked me through exactly how employer contributions work for S-corps and confirmed that I should absolutely be making employer contributions to my solo 401k instead of using a taxable account. She explained that as both employer and employee, I'm essentially getting two separate buckets of tax-advantaged contributions. The specialist also warned me about some common documentation mistakes S-corp owners make with their solo 401ks that can trigger audits. That alone was worth it. Never thought I'd say this, but the IRS was actually super helpful once I could actually talk to someone!

19 Don't overthink this. Max out your solo 401k contributions (both employee and employer portions) before putting a single dollar in taxable accounts. The math isn't even close. For 2025, you can contribute: - $23,000 as employee contribution (or $30,500 if you're 50+) - Up to 25% of your compensation as employer contribution - Total combined limit of $69,000 ($76,500 if 50+) Since you're the owner of an S-corp, the employer contribution is a business expense that reduces your pass-through income. This is FAR better than taking that money as income, paying taxes on it, then investing what's left in a taxable account where you'll pay taxes on dividends and gains.

•3 What about access to the money though? I'm worried about locking up too much in retirement accounts that I can't touch until 59½. Don't you lose some flexibility with a 401k vs brokerage account?

•19 That's a legitimate concern. There are several ways to access retirement funds early if needed. Look into Substantially Equal Periodic Payments (SEPP/72t), which allows penalty-free withdrawals before 59½. You can also access Roth conversion ladders or take loans from some solo 401k plans. That said, it's reasonable to keep some money in taxable accounts for flexibility. But from a pure tax-efficiency standpoint, max the tax-advantaged accounts first, then use taxable accounts for additional savings. Most financial planners recommend having both for different purposes - retirement accounts for long-term growth and taxable accounts for flexibility and earlier goals.

6 Question for anyone who's done this - do you need a special type of solo 401k plan to make employer contributions? My financial advisor set up my solo 401k last year but never mentioned anything about employer matching. Do I need to change my plan?

•22 Most solo 401k plans allow for employer contributions, but not all. Check your plan documents or call your provider. I had to specifically ask about this when setting up mine through Fidelity. Some of the basic plans only allow employee contributions but can be upgraded.

14 As a newcomer here but someone who went through this exact decision process last year, I can confirm that maxing out both employee and employer contributions to your solo 401k is absolutely the way to go for tax efficiency. What helped me understand this was breaking down the numbers: if I took $25,000 as an S-corp distribution to invest in a taxable account, I'd pay income tax on that $25,000 first (let's say 22% = $5,500), leaving me with $19,500 to invest. Then I'd pay taxes annually on dividends and capital gains. But if I make that same $25,000 as an employer contribution to my solo 401k, it reduces my S-corp's taxable income dollar-for-dollar, meaning I save that entire $5,500 in taxes upfront. Plus the money grows tax-deferred. The only real consideration is liquidity - make sure you have adequate emergency funds in accessible accounts first. But for retirement savings specifically, the 401k route beats taxable investing by a wide margin when you run the math.

•6 This breakdown is really helpful, thanks! I'm just starting to research this topic and the tax math makes sense when you put it that way. Quick question - when you say "employer contribution," are you literally paying yourself as the employer? How does that work practically? Do you just write a check from the business account to the 401k provider, or is there a specific process you have to follow?
