Can contributing to a 401k reduce your MAGI enough to qualify for Roth IRA contributions?

Thanks for explaining this! So just to be clear, if I max out my traditional 401k at $23,000, that would bring my MAGI down to $127,000 (assuming $150k income), which would put me well under the Roth IRA limit? Also, does contributing to an HSA help lower MAGI too?

Yes, in your example, contributing $23,000 to your traditional 401k would reduce your MAGI from $150,000 to approximately $127,000, which would indeed put you well below the Roth IRA contribution limit for 2025! HSA contributions absolutely help lower your MAGI as well. For 2025, you can contribute up to $4,150 for self-only coverage or $8,300 for family coverage (plus an extra $1,000 if you're 55 or older). So combining max 401k and HSA contributions can be a powerful strategy for reducing your MAGI.

Did you have to pay for this service? I'm trying to figure out if I need to adjust my withholdings for next year and this sounds helpful, but I don't want to spend a ton on tax software when I'm trying to save money.

How accurate was it? I've tried other tax calculators that were way off because they didn't account for state taxes or other deductions properly. Does it handle complex situations like side income or rental properties?

You can actually try it out with basic features before committing to anything. It was worth it for me because it helped me optimize my retirement contributions and saved me more than it cost. It's extremely accurate in my experience. The tax engine takes into account federal, state, and local taxes. I have a small side business and some dividend income, and it handled everything correctly. It even helped me identify some business deductions I was missing. I can't speak to rental properties specifically, but it does handle investment income well.

Wait, you're saying there's a service that gets you through to the IRS? How does that even work? Isn't the whole point of the IRS phone system that NOBODY can get through? Sounds like a scam to me.

Does this actually work for complicated tax questions? Last time I called the IRS the person I finally reached after 2 hours just read me the same info from the website I'd already seen. I need someone who can actually understand complex MAGI calculations.

It works by using their technology to navigate the IRS phone trees and hold system for you. When an agent is about to pick up, you get a call connecting you. It's not a scam - they don't ask for any tax info, they just get you through the phone system. I had a really good experience with my question about MAGI calculations. I think it depends on which agent you get, but being able to actually reach someone (instead of getting disconnected after hours on hold) gives you better odds of finding a knowledgeable person. If the first agent can't help with complex questions, you can always ask to be transferred to a specialist.

But if your spouse isn't covered by a workplace plan, doesn't that change the deductibility limits for your Traditional IRA? I think my wife might still be able to take a deduction even though I'm over the limit with my job's 401k. Would her deductible IRA contribution affect our joint MAGI for Roth purposes?

You're right that the rules are different for spouses. If you're married filing jointly and only one spouse is covered by a workplace plan, the non-covered spouse can take a full deduction for their Traditional IRA contributions until your joint MAGI hits $218,000 in 2025. And yes, that deductible Traditional IRA contribution from the non-covered spouse would reduce your joint MAGI, which could help with Roth IRA eligibility. For married filing jointly, the Roth contribution phase-out range is $230,000-$240,000 for 2025, so that spousal Traditional IRA deduction could potentially help get you under the threshold if you're close to the limit.

Omg thank you for explaining this! I've been so confused about why some calculators give me different numbers. I have student loan interest deduction and didn't realize I needed to add that back for MAGI purposes. No wonder my calculations were off last year and I accidentally over-contributed to my Roth!

This is such a comprehensive overview! As someone just starting to navigate these waters, the point about RMDs and tax brackets in retirement really hits home. I've been so focused on the immediate benefit of getting under the MAGI limit that I hadn't really thought about the long-term tax implications of loading up too heavily on traditional 401k contributions. The Roth conversion ladder strategy sounds intriguing but also pretty complex. Do you have any rules of thumb for how to balance traditional vs Roth contributions when you're right in that income sweet spot where you could qualify for Roth IRA if you adjust your 401k contributions? I'm wondering if there's an optimal split that gives you the best of both worlds - current tax savings plus future tax flexibility. Also, regarding the timing of income recognition - are there common ways people have control over bonus timing, or is that usually pretty locked in by company policies? I'm at a tech company and our bonuses are typically paid out in March, so I'm wondering if there are any strategies that could apply to my situation. Thanks for bringing the long-term perspective to this discussion - it's easy to get caught up in optimizing for this year and lose sight of the bigger picture!

@53dc090fcbaf Great perspective on the long-term planning aspect! As someone who's been wrestling with this exact optimization problem, the RMD consideration is something I definitely overlooked. Regarding @bd69a9972b96's question about balancing traditional vs Roth - I've been wondering about this too. My current thinking is to contribute just enough to traditional 401k to get under the Roth IRA limit, then split any additional retirement savings between Roth 401k contributions and the now-available Roth IRA. This way I'm getting some of both tax treatments without going overboard on the traditional side. For bonus timing, it's probably worth having a conversation with HR or finance about company policies. Some companies have flexibility around deferred compensation or might allow you to shift the timing by a few weeks if you ask early enough in the process. Won't hurt to ask! One thing I'm curious about - do you typically recommend clients prioritize maxing out the Roth IRA space first (since it's more flexible for early withdrawals) before adding more to employer 401k beyond the match? Or does the employer match make the 401k contributions more attractive regardless of the tax treatment?

@53dc090fcbaf @bd69a9972b96 @0c2b2f95f842 This conversation has been so helpful! As someone who just discovered this community while researching this exact question, I love seeing the mix of personal experiences and professional advice. I'm in a similar spot - making about $152k and trying to figure out the optimal strategy. Based on everything discussed here, it sounds like the key is finding that sweet spot where you contribute just enough to traditional 401k to qualify for Roth IRA, then potentially split additional savings between Roth 401k and the Roth IRA. One thing I'm still unclear on - if I'm doing this optimization, should I prioritize getting the full $7,000 into a Roth IRA before putting additional money into Roth 401k? I know the IRA has more flexibility for withdrawals, but the 401k has higher contribution limits. For someone in their early 30s, which would you prioritize after getting the employer match? Also, has anyone here actually used the taxr.ai tool that was mentioned earlier? I'm tempted to try it but want to hear more real experiences before uploading my financial info anywhere.

@1fb7c9e34a09 Great questions! For prioritization in your early 30s, I'd generally recommend maxing the Roth IRA first after getting your employer match. Here's why: 1. **More investment options** - IRAs typically offer broader fund selection than employer 401k plans 2. **Withdrawal flexibility** - You can withdraw Roth IRA contributions penalty-free anytime, making it a better emergency backup 3. **No RMDs** - Roth IRAs never have required distributions, unlike Roth 401ks So my suggested order would be: employer match → enough traditional 401k to qualify for Roth IRA → max Roth IRA ($7,000) → additional Roth 401k if you want to save more. Regarding taxr.ai - I haven't used it personally, but @a45dff51643a mentioned good results earlier in this thread. For tax planning tools, I always recommend starting with their free features first to test accuracy against your known tax situation before upgrading to paid features. The strategy you're describing sounds solid for someone at $152k - just make sure to account for any variable income throughout the year so you don't accidentally go over the MAGI limits!

This is such a helpful breakdown! I'm just starting my career and making around $85k, so I'm not hitting the Roth IRA income limits yet, but I want to understand this strategy for when my income grows. The point about investment flexibility really resonates with me - my current 401k plan has pretty limited fund options and high expense ratios. Being able to choose low-cost index funds through someone like Vanguard or Fidelity for the IRA portion seems like it could make a meaningful difference over decades of compound growth. One follow-up question: when you say "get employer match → contribute enough to traditional 401k to qualify for Roth IRA → max out Roth IRA," are you suggesting that ALL the additional 401k contributions should be traditional/pre-tax? Or could some of that MAGI-reducing contribution be split between traditional and Roth 401k as long as the total amount gets you under the income limit? I'm thinking ahead to when I might be in this situation and wondering if there's value in having some Roth 401k contributions in the mix, or if the traditional contributions are always better for this specific strategy since you need to reduce your MAGI anyway.

Great question about mixing traditional and Roth 401k contributions! You're absolutely right to think strategically about this. The key insight is that only TRADITIONAL (pre-tax) 401k contributions reduce your MAGI. Roth 401k contributions are made with after-tax dollars, so they don't help with getting under the income limit for Roth IRA eligibility. So for this specific strategy, you'd want those MAGI-reducing contributions to be entirely traditional/pre-tax. Once you've contributed enough traditional 401k to get under the Roth IRA limit, then you could consider splitting any additional 401k contributions between traditional and Roth if you want tax diversification. For example, if you need $15,000 in traditional 401k contributions to get your MAGI under the limit, that entire $15,000 should be traditional. But if you want to contribute more (say another $8,000), you could potentially split that additional amount between traditional and Roth 401k based on your tax planning preferences. The beautiful thing about starting to think about this early in your career is you have time to adjust as your income grows. At $85k, you're in a great position to build that foundation and understand the strategy before you actually need it! @69be13697e50's prioritization framework is spot on - it's all about optimizing in the right order to get the maximum benefit from each account type.

Great question about mixing traditional and Roth 401k contributions! You're thinking ahead really well for someone at $85k - this strategy will definitely be relevant as your income grows. To answer your question: for the MAGI reduction strategy to work, you need to use traditional/pre-tax 401k contributions specifically, since only those reduce your taxable income. Roth 401k contributions are made with after-tax dollars, so they don't help lower your MAGI for Roth IRA qualification purposes. So the sequence would be: employer match → enough traditional 401k to get under Roth IRA limits → max Roth IRA → then you could consider Roth 401k for any additional contributions if you want tax diversification. The key insight is that when you're right at the income threshold, every dollar of traditional 401k contribution serves double duty: it gives you the immediate tax deduction AND enables Roth IRA eligibility. That's hard to beat from an optimization standpoint. Once you've secured your Roth IRA space and you're contributing beyond what's needed for MAGI reduction, then you can absolutely mix in Roth 401k contributions for tax diversification. But for the specific goal of getting under the income limits, traditional contributions are the only ones that help. You're smart to be thinking about this early - having a plan for when your income grows will put you way ahead of most people!

Great question about mixing traditional and Roth 401k contributions! You're absolutely right to think strategically about this. For the MAGI reduction strategy, those contributions specifically need to be traditional/pre-tax 401k to actually lower your MAGI. Roth 401k contributions are made with after-tax dollars, so they don't reduce your MAGI at all - they won't help you qualify for Roth IRA eligibility. However, once you've contributed enough traditional 401k to get under the Roth IRA income limit, any additional 401k contributions could theoretically be split between traditional and Roth based on your tax diversification goals. That said, at your current $85k income level, you're probably in a lower tax bracket now than you'll be in retirement, so maximizing Roth contributions (IRA first, then Roth 401k) while you're in this sweet spot makes a lot of sense. As your income grows and you start needing the traditional 401k contributions for MAGI management, you'll naturally get that tax diversification. The key insight is that the MAGI reduction piece has to be traditional contributions - but your overall retirement strategy can still include Roth elements through the IRA and any additional 401k space after you've done the MAGI math.

Great question! You're right to think ahead about this strategy. When you're trying to reduce MAGI to qualify for Roth IRA contributions, you specifically need traditional/pre-tax 401k contributions because only those reduce your taxable income. Roth 401k contributions are made with after-tax dollars, so they don't help lower your MAGI at all. So in the strategy @69be13697e50 outlined, that middle step of "contribute enough to traditional 401k to qualify for Roth IRA" would need to be ALL traditional contributions to get the MAGI reduction you need. However, once you've contributed enough traditional 401k to get under the Roth IRA income limit, then any ADDITIONAL 401k contributions could be split between traditional and Roth based on your preferences. At that point you're not trying to reduce MAGI further, so you can choose the tax treatment that makes sense for your situation. The beauty of this approach is you get the best of both worlds - you use traditional 401k contributions as a "tool" to unlock Roth IRA eligibility, but you're not forced to put everything in traditional accounts. You still end up with a nice mix of pre-tax and Roth money for retirement tax diversification. It's smart that you're thinking about this early in your career - understanding these strategies now will serve you well as your income grows!

However, once you've contributed enough traditional 401k money to qualify for the Roth IRA, any ADDITIONAL 401k contributions could absolutely be Roth if you want that tax diversification. So the sequence might look like: 1. Get employer match (however your company structures it) 2. Contribute enough to traditional 401k to get MAGI under Roth IRA limits 3. Max out Roth IRA ($7,000) 4. Any remaining 401k contributions could be traditional OR Roth depending on your tax strategy The key insight is that you only need enough traditional contributions to hit your MAGI target - beyond that, you have flexibility. Some people like having both traditional and Roth 401k money for tax diversification in retirement, especially if they expect to be in higher tax brackets later. You're smart to be thinking about this early in your career! Having a plan for when your income grows will make the transitions much smoother.
