Can I deduct traditional IRA contributions if I contribute to a Roth 401k at work?
So I've been maxing out my Roth 401k at work every year (plus getting some sweet employer matching). I also max out my TRADITIONAL IRA contributions separately. Here's where I'm confused... I'm doing my taxes through H&R Block and when I get to the IRA section, it's telling me my TRADITIONAL IRA contribution is NOT tax-deductible because I participate in a work retirement plan. But wait - my work plan is a ROTH 401k where I'm already paying taxes on those contributions! Shouldn't my TRADITIONAL IRA contributions be tax-deductible in this case since they're my only pre-tax retirement savings? The whole point of having one of each was to diversify my tax situation. I've searched online but all the examples I find are either Roth with Roth, or Traditional with Traditional, or Traditional 401k with Roth IRA. I can't find a clear answer about my specific Roth 401k + Traditional IRA combo. Is H&R Block's guidance wrong here? Just want to make sure I'm getting any deduction I'm entitled to! Anyone dealt with this specific situation before?

The H&R Block guidance is actually correct, but I understand your confusion! The IRS doesn't distinguish between Roth 401k and Traditional 401k when determining eligibility for deducting Traditional IRA contributions - what matters is simply that you're covered by a retirement plan at work. If you're covered by any workplace retirement plan (Roth or Traditional 401k), your ability to deduct Traditional IRA contributions depends on your modified adjusted gross income (MAGI). For 2024, the deduction phases out between $77,000-$87,000 for single filers and $123,000-$143,000 for married filing jointly. The reasoning is that the government already provides tax advantages through your workplace plan, so they limit additional tax breaks. Even though your Roth 401k contributions aren't giving you a current-year tax break, you're still getting the benefit of tax-free growth and withdrawals.

•But doesn't that seem unfair? Someone with a Traditional 401k gets a tax break on those contributions AND might get another tax break on Traditional IRA contributions if their income is low enough. Meanwhile someone with a Roth 401k gets no upfront tax break on their 401k but still has the same income limits for deducting Traditional IRA contributions! Am I understanding that right?

•You're understanding it correctly, but remember that tax advantages balance out eventually. With a Traditional 401k, you get tax breaks now but pay taxes on withdrawals later. With a Roth 401k, you pay taxes now but get tax-free withdrawals later. The IRS isn't trying to give extra advantages to either approach - they're just setting consistent rules about participation in workplace plans. It might feel unfair in your specific situation, but consider that someone with a Traditional 401k who's below the income limits is essentially "double-dipping" on current tax advantages, while you're diversifying between current (Traditional IRA) and future (Roth 401k) tax advantages.

After struggling with this exact situation last year, I found a tool that saved me tons of time figuring out my retirement contribution strategy. I used https://taxr.ai to analyze my retirement accounts and tax situation. It showed me exactly how my Roth 401k affected my Traditional IRA deductibility based on my specific income level. The tool analyzed my income, retirement contributions, and tax brackets to show me what was most optimal. It also explained that even if I couldn't deduct my Traditional IRA contributions, I could still benefit from a backdoor Roth conversion depending on my situation. Seriously made things so much clearer than the generic explanations from tax software!

•How does taxr.ai handle calculating the phase-out ranges? My income is right at the edge where I might be able to deduct part of my Traditional IRA contribution even though I have a workplace plan.

•I'm skeptical of these tax tools - do they actually give different advice than just reading the IRS publications? And how do they handle state-specific tax issues related to retirement accounts? Some states have different rules about taxing retirement contributions and distributions.

•It actually walks you through the phase-out calculations step by step, showing exactly how much is deductible at your specific income level. You can even adjust income values to see how different scenarios would affect your deduction amount. Super helpful if you're near the threshold. For state-specific rules, it lets you select your state and then applies those specific regulations to your situation. I'm in California which has some quirky rules about retirement accounts, and it flagged those differences compared to federal treatment. Definitely more personalized than just reading generic IRS publications which can be really hard to interpret for your specific situation.

Just wanted to update everyone - I tried the taxr.ai tool mentioned above after struggling with this same Roth 401k + Traditional IRA question. It was surprisingly helpful! The analysis showed me that I was just over the income limit for deducting my Traditional IRA, but it also showed me how I could still benefit from non-deductible contributions and potentially doing backdoor Roth conversions. The visualization of future tax savings really put things in perspective - even without the immediate deduction, my retirement strategy still makes sense long-term. It also suggested a few adjustments to my withholding that could save me about $1,200 this year. Definitely cleared up my confusion about how different retirement accounts interact!

After spending HOURS on hold trying to get someone at the IRS to explain this exact situation to me, I finally found a service called Claimyr that got me connected to an actual IRS representative in under 20 minutes! You can check out how it works at https://claimyr.com or see a demo at https://youtu.be/_kiP6q8DX5c The IRS agent confirmed exactly what the first commenter said - being covered by ANY workplace retirement plan (Roth or Traditional) affects your Traditional IRA deductibility based on income limits. She also explained that even if you can't deduct your contributions, you can still make non-deductible contributions to a Traditional IRA and track your basis with Form 8606, which might be beneficial for future backdoor Roth conversions. Saved me from making a mistake on my taxes and potentially facing penalties down the road!

•How does this service actually work? Do they just call the IRS for you or what? I've been trying to get through for weeks about a similar retirement plan question.

•Yeah right. The IRS phone system is completely broken. I've tried calling dozens of times and never get through. I find it hard to believe any service could actually fix that fundamental problem.

•They use a proprietary system that navigates the IRS phone tree and waits on hold for you. Once they reach an actual human, they call you and connect you directly to the IRS representative. It's basically like having someone wait on hold in your place. I was super skeptical too, but it actually works. I spent weeks trying to get through on my own before trying this. The way they explained it, they've figured out the optimal times to call and how to navigate the system efficiently. I was genuinely surprised when my phone rang and there was an actual IRS agent on the line ready to help with my specific question.

Ok I need to eat some humble pie here. After posting my skeptical comment above, I was still frustrated about not getting answers about my retirement account questions. I reluctantly tried Claimyr and... it actually worked. Within 15 minutes I was talking to an IRS tax specialist who clarified my Roth 401k and Traditional IRA questions. The agent confirmed that it doesn't matter if your employer plan is Roth or Traditional - being covered by ANY workplace plan means the same income limits apply for Traditional IRA deductibility. But she also explained that I could still make non-deductible contributions and keep track of my basis, which might be useful for tax planning later. Honestly saved me so much frustration compared to the dozen failed attempts I made calling directly.

Another option to consider is whether you're eligible for a Roth IRA instead of the Traditional IRA. If your income is below the Roth IRA limits (higher than the Traditional IRA deductibility limits), you could switch to contributing to a Roth IRA. That way, you'd still get tax advantages, just on the withdrawal end instead of the contribution end. For 2024, Roth IRA contributions phase out between $146,000-$161,000 for single filers and $230,000-$240,000 for married filing jointly. Worth considering if you're in that income range!

•Thanks for this suggestion! My income is actually within the Roth IRA eligibility range but below the higher threshold. I was trying to diversify between pre-tax and post-tax retirement savings, but if I can't deduct the Traditional IRA contributions anyway, switching to Roth IRA might make more sense. Would there be any advantage to keeping non-deductible Traditional IRA contributions rather than just going with the Roth IRA directly?

•If you can't deduct your Traditional IRA contributions and you're eligible for a Roth IRA, there's generally little advantage to making non-deductible Traditional IRA contributions instead of contributing directly to a Roth IRA. The main exception would be if you're planning to use the "Backdoor Roth" strategy in the future. Some people make non-deductible Traditional IRA contributions and then immediately convert them to Roth. This can be useful for those who exceed the Roth IRA income limits. However, this gets complicated if you already have other pre-tax money in Traditional IRAs due to the "pro-rata" rule.

Has anyone used TurboTax for this situation instead of H&R Block? I'm wondering if different tax software handles the Roth 401k + Traditional IRA combination differently or if they all follow the same logic.

•I used TurboTax this year with the exact same retirement setup (Roth 401k + Traditional IRA), and it also said my Traditional IRA wasn't deductible because I participate in a workplace plan. So I think all the major tax software follows the same IRS rules on this.
