Can I contribute to a SEP IRA if I have W2 income and 1099 income from separate employers?
I have a retirement planning question that's been bugging me. I work full-time for Company XYZ (W2 employee) and I've already maxed out my 401k contributions for the year ($22,500 for 2025). My husband runs his own S-Corporation, and I also do some work for his business. We're trying to figure out the best way to structure my compensation from his business to maximize our retirement savings. We have two options we're considering: Option 1: I receive a 1099 from my husband's S-Corp for about $35k at year-end. If we go this route, can I contribute all $35k to a SEP IRA, or is there some limit I need to be aware of since I already maxed out my 401k elsewhere? Option 2: I receive a W2 for $35k from the S-Corp in addition to my regular employer's W2. Since I've already hit my 401k max through my main job, I'm pretty sure I can't contribute more to another 401k. But could I still contribute to a SEP IRA in this scenario? If yes, what would be the limit? Which option would be better for maximizing retirement savings? Thanks in advance!

The key here is understanding how the IRS treats these different scenarios regarding retirement accounts. For Option 1 (1099 income): Yes, you can establish a SEP IRA for your self-employment income. However, you can't contribute "all $35k" - the limit for SEP IRA contributions is 25% of your net self-employment income (after deducting the self-employment tax). So if your net income is $35k, your maximum SEP contribution would be around $8,750. This is completely separate from your 401k maximum at your W2 job. For Option 2 (second W2): You're correct that you can't contribute more to another 401k since you've hit the $22,500 employee contribution limit (for 2025) at your main job. However, the S-Corp could still make employer contributions to a retirement plan for you. Unfortunately, you cannot establish a SEP IRA for W2 income - SEP IRAs are only for self-employment income. The better option depends on other factors like tax planning and business expenses, but Option 1 typically gives you more flexibility for making your own retirement contributions through the SEP IRA.

Wait I'm confused. If OP's husband has an S-Corp, isn't the 1099 income considered self-employment income? So could she still do the SEP IRA with the 1099 option? And if she goes with option 2, could the S-Corp do a SIMPLE IRA instead or something?

Yes, the 1099 income is indeed considered self-employment income, which is why she can establish a SEP IRA under Option 1. The 1099 income is separate from her W2 job, allowing her to make SEP IRA contributions up to 25% of her net self-employment earnings. For Option 2, you're right that the S-Corp could potentially establish a SIMPLE IRA or even a Solo 401(k) where the S-Corp makes employer contributions. The S-Corp (as the employer) could contribute up to 25% of her W2 compensation from the S-Corp, up to the total annual limits. This would be completely separate from her personal 401(k) contribution limits at her other job.

I was in a similar situation last year and found this super helpful tax tool at https://taxr.ai that analyzes your specific situation to maximize retirement contributions across multiple income sources. It showed me exactly how much I could contribute to my SEP IRA based on my 1099 income while accounting for my maxed-out 401(k) at my day job. The tool actually walks you through the specific calculations for SEP IRA contribution limits and shows you how the 25% limit is applied to your net earnings after self-employment tax deductions. It also analyzed whether I should take the 1099 or W2 route for my side gig by comparing total tax implications. Definitely saved me from making some big mistakes!

This sounds interesting but did it actually save you money? Like did it find deductions you wouldn't have known about otherwise? I'm also juggling W2 and 1099 income and the retirement account rules are so confusing.

I'm skeptical about these tax tools. Wouldn't an accountant be a better choice for this kind of situation? There's a lot of nuance with S-Corps and SEP IRAs. How accurate was the advice compared to what a CPA would tell you?

It absolutely saved me money! The tool identified that I was calculating my SEP IRA contribution wrong - I was using gross income instead of net income after SE tax, which would have caused me to over-contribute and possibly face penalties. It found about $3,800 in additional deductions I could take for my business that I hadn't considered. Regarding using an accountant, I actually showed the results to my CPA afterward, and she was impressed with the accuracy. The difference is that I could run different scenarios instantly (W2 vs 1099, different income levels, etc.) without paying my CPA's hourly rate for each calculation. I still used my accountant for filing, but the tool helped me make informed decisions beforehand and come prepared with questions.

Just wanted to follow up and say I tried the taxr.ai tool that was mentioned above, and wow - it was exactly what I needed! I've been struggling with this exact W2/1099 retirement contribution confusion. The tool showed me that in my case, taking 1099 income from my side gig would allow me to contribute about $9,400 to a SEP IRA even though I've already maxed my 401k at my primary job. It even calculated the exact self-employment tax I'd owe and showed me how that factors into the contribution limit. The analysis made it super clear which option would leave me with more retirement savings after taxes. I was going to just take a W2 from my second job because it seemed simpler, but now I see I'd be leaving thousands in potential retirement savings on the table. Definitely worth checking out if you're in this situation!

If you're trying to reach the IRS to confirm retirement contribution rules for multiple income sources, good luck! I spent 3+ hours on hold last month trying to get clarity on SEP IRA limits with W2 and 1099 income. Finally discovered https://claimyr.com and their video demo at https://youtu.be/_kiP6q8DX5c - they actually got me connected to an IRS agent in under 20 minutes! The agent confirmed that with Option 1 (1099 income), you can contribute to both your employer's 401k AND a SEP IRA for your self-employment income, but with different limits for each. For Option 2, the S-Corp could make employer contributions to a retirement plan for you even if you've maxed out your employee contributions elsewhere. Ended up saving me from making a major filing mistake.

How does that even work? Is this legit? I thought the IRS phone system was completely broken. Are they just constantly calling until they get through?

Yeah right. No way this works. I've literally never gotten through to a real person at the IRS no matter how many times I've tried or how long I've waited. Sounds like a scam to me.

It works by using a system that navigates the IRS phone tree and waits on hold for you. Once they reach a representative, you get a call to connect with the agent. It's not constantly calling - they just have technology that holds your place in line so you don't have to. Regarding whether it's legit - I was skeptical too! But it absolutely worked for me. They don't ask for any sensitive information - you just give them your phone number so they can call you when they reach an agent. The service handles the painful waiting process, and you only get charged if they actually connect you. I was planning to wait on hold myself for hours again, but this saved me a huge headache.

I need to eat my words and apologize for my skepticism about Claimyr. After posting my doubtful comment, I was still desperate to talk to the IRS about some complicated retirement account questions (similar to the original post about W2/1099/SEP IRA situations). I decided to try the service despite my doubts, and I'm completely shocked - it actually worked! I got connected to an IRS agent in about 15 minutes after trying unsuccessfully for WEEKS on my own. The agent walked me through exactly how the contribution limits work when you have both W2 and 1099 income and confirmed I could contribute to both my employer 401k and a SEP IRA based on my self-employment income. Seriously, I've never been so happy to be wrong about something. Would have saved me so much stress if I'd tried it sooner instead of spending hours listening to the IRS hold music.

Another thing to consider is that with Option 1 (1099), you'll have to pay self-employment tax (15.3%) on that income. With Option 2 (W2), the S-Corp would pay half of the FICA taxes. So even though Option 1 gives you the SEP IRA opportunity, you might end up paying more in taxes overall. It's worth running the numbers on both scenarios including all taxes, not just focusing on the retirement contribution aspect.

But can't you deduct half of the self-employment tax on your personal return? Also with an S-Corp, don't you have to pay yourself a reasonable salary anyway? I thought you couldn't just take everything as distributions to avoid employment taxes.

Sophie Footman
You're right that you can deduct half of the self-employment tax on your personal return, which does offset some of the tax impact. Regarding S-Corps, yes, if you're an owner, you need to pay yourself a "reasonable salary" before taking distributions. But in this case, OP isn't the owner - her husband is. So if she's legitimately performing services for the S-Corp, they have flexibility in how they compensate her. They could choose either W2 or 1099 depending on the nature of the work and their tax planning needs. Each approach has different implications for retirement planning, taxes, and administrative requirements.

Has anyone considered a Solo 401k instead of a SEP IRA for the self-employment income? With a Solo 401k, you can potentially contribute more than with a SEP IRA at the same income level because you can make both "employer" and "employee" contributions, even if you've already maxed your employee contributions at another job.

I thought you couldn't do employee contributions to a Solo 401k if you've already maxed out at another employer? The $22,500 limit (for 2025) is per person across all 401k plans, not per employer, right?
0 coins
Mateo Silva
You're absolutely correct! The $22,500 employee contribution limit for 2025 is per person across ALL 401(k) plans, not per employer. So if OP has already maxed out employee contributions at her W2 job, she cannot make additional employee contributions to a Solo 401(k) for her self-employment income. However, she could still make employer contributions to a Solo 401(k) based on her self-employment income (up to 25% of net self-employment earnings). But at that point, there's really no advantage over a SEP IRA since both would allow the same employer contribution limits. The SEP IRA is actually simpler to set up and maintain, so it would probably be the better choice in this situation.

This has been an absolutely fantastic discussion! As someone who's been wrestling with similar W2/1099 retirement planning questions, I can't thank everyone enough for sharing such detailed insights. I wanted to add one consideration that might be helpful for others in this situation: **timing of income recognition**. With Option 1 (1099), you have more flexibility in when you actually receive/recognize the income within the tax year, which could be valuable for tax planning. For example, if you have a particularly high income year from your W2 job, you might delay invoicing for 1099 work until the following year to smooth out your tax brackets. Also, I noticed several people mentioned the taxr.ai and claimyr.com tools - has anyone compared these to working with a fee-only financial planner who specializes in tax planning? I'm wondering if the personalized advice might be worth the additional cost for complex situations like this, especially when you factor in long-term planning beyond just the current tax year. One last thought: for anyone considering Option 1, don't forget about the potential to deduct business expenses related to your 1099 work (home office, equipment, etc.) which could further improve the tax efficiency compared to Option 2. This thread should honestly be pinned or turned into a FAQ - it's the most comprehensive explanation of these retirement account rules I've seen anywhere!

Great point about the income timing flexibility with Option 1! That's a really valuable tax planning tool that I hadn't considered. Being able to shift income between tax years based on your overall tax situation could definitely help with bracket management. Regarding the tools vs. fee-only financial planner question - I think it really depends on the complexity of your overall financial situation. For someone just trying to understand the basic retirement account rules and run some calculations, the automated tools seem like a great starting point. But if you have multiple income sources, complex tax planning needs, estate planning considerations, or just want ongoing advice as your situation changes, a fee-only planner who specializes in tax planning is probably worth the investment. The business expense deduction point is huge too! I completely overlooked that Option 1 would allow you to deduct legitimate business expenses related to your 1099 work. Depending on what type of work you're doing for the S-Corp, this could include home office expenses, equipment, software, professional development, etc. Those deductions could significantly improve the overall tax efficiency of Option 1. This discussion has definitely convinced me that Option 1 offers more flexibility and potential benefits, even though it requires more planning and administrative work. Thanks to everyone for such a thorough analysis!
