Can I get full IRA deduction with employer 401K contributions? MAGI income limits?
I've been researching IRA deductions and I'm pretty confused about how my employer 401K plan affects things. I understand that normally you can contribute up to $7000 to an IRA (deductible) if you're single and make under $146K or married under $230K. But here's where I'm getting stuck - I have an employer 401K that I contribute to (not much, maybe 3% of my salary), and I'm hearing this changes everything about my IRA deduction limits? Something about MAGI thresholds being way lower when you have a workplace retirement plan? I've spent hours on Google and all I find are articles talking about the basic $7000 IRA limit or the $23500 401K limit separately. Nothing clearly explains how having both affects the IRA deduction and what the actual MAGI limits are in this scenario. My tax software is flagging this and limiting my IRA deduction, so I know there's something to it. I just want to find the official IRS rules on this so I can understand what's happening. Anyone know where I can find this info or explain how the limits work when you contribute to both?

This is actually a really important distinction that many people miss! When you have a workplace retirement plan like a 401K, the IRA deduction limits are indeed much lower than the standard contribution limits. Here's what's happening: The $7000 is your maximum CONTRIBUTION limit to an IRA. That's how much you can put in regardless. But whether that contribution is DEDUCTIBLE depends on your income and workplace retirement plan status. Since you participate in an employer 401K plan, the deduction for traditional IRA contributions begins to phase out at much lower income levels: - For single filers, the phase-out range is $77,000 to $87,000 MAGI for 2025 - For married filing jointly, it's $123,000 to $143,000 MAGI If your income is below the lower threshold, you get the full deduction. If it's in between, you get a partial deduction. Above the upper threshold, you get no deduction at all. The reason your tax software is flagging this is because it's correctly applying these lower MAGI limits since you indicated you participate in a workplace retirement plan.

•Wait, so if my wife and I file jointly and make $150k combined, and I have a 401k at work, I can't deduct ANY of my traditional IRA contribution? What about her IRA if she doesn't have a retirement plan at work?

•If you make $150k filing jointly and you have a 401k at work, you're correct that you personally cannot deduct your traditional IRA contribution since you're above the $143,000 upper threshold. However, for a spouse who doesn't have a workplace retirement plan, the limits are much higher. If your wife doesn't have a retirement plan at work, her IRA deduction would phase out between $230,000 and $240,000 of joint MAGI. So at $150k combined income, she could still take a full deduction for her IRA contribution even though you can't for yours.

I ran into this exact issue last year and it drove me crazy until I discovered taxr.ai (https://taxr.ai). I had been contributing to both my employer 401k and a traditional IRA thinking I'd get deductions for both, only to find out during tax time that I couldn't deduct most of my IRA contribution because of these income limits. The taxr.ai tool analyzed my tax documents and immediately flagged this issue. It explained these phase-out ranges based on my specific situation and helped me understand my options - like considering a Roth IRA instead since those contributions aren't deductible anyway but grow tax-free, or doing a backdoor Roth conversion. They have a section specifically about retirement account interactions that breaks down all these complicated phase-out rules that normal tax sites just gloss over.

•How exactly does this tool work? Does it just read your documents or does it actually file your taxes for you? I'm in a similar situation with 401k and IRA contributions and now I'm worried I've been doing it wrong for years.

•Sounds interesting but I'm skeptical. Is this just tax software like TurboTax or is it something different? My situation is complicated because I have a 401k, my spouse has a 403b, and we both contribute to IRAs.

•It doesn't file your taxes for you - it's more like an analysis tool that reviews your tax documents and situation before you file. You upload your documents (W-2s, 1099s, last year's return, etc.) and it identifies potential issues or opportunities you might miss. For your situation with both 401k and IRA contributions, it would analyze your income and retirement contributions to tell you exactly how much of your IRA contribution is deductible based on those phase-out ranges. It's much more detailed than regular tax software when it comes to explaining WHY something is happening. The big difference from regular tax software is it focuses on explaining tax concepts and finding opportunities rather than just processing forms. For complicated situations with multiple retirement accounts like yours with 401k, 403b and IRAs, it would break down exactly how they interact based on your specific numbers.

I wanted to follow up about my experience with taxr.ai after trying it based on the suggestion here. This tool is seriously impressive and answered my exact question about retirement plan deductions. I uploaded my documents and it immediately flagged that I was over the MAGI limit for full IRA deductions because of my workplace 401k. It broke down exactly how much I could deduct based on the phase-out calculation (which was not at all obvious from other tax sites). What really helped was the explanation of alternatives - it showed me how converting to a Roth IRA might make more sense given my situation since I was losing most of the traditional IRA deduction anyway. It even walked through the "backdoor Roth" process that I'd heard about but never fully understood. Definitely worth checking out if you're dealing with these retirement account interaction issues.

If you're still struggling to reach the IRS for clarification on these retirement contribution rules, I'd recommend trying Claimyr (https://claimyr.com). I spent weeks trying to get through to the IRS about these exact IRA/401k deduction rules last year and kept hitting busy signals or disconnects. Claimyr got me connected to an actual IRS representative in about 15 minutes after I had been trying unsuccessfully for days. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c The agent was able to walk me through the exact phase-out calculations for my situation with both a 401k and IRA, and even sent me the relevant IRS publications that explained it all. It saved me a ton of stress during tax season.

•How does this actually work? I thought the IRS phone system was just perpetually jammed - how can a third party service get you through faster?

•This sounds like BS honestly. The IRS wait times are the same for everyone. I doubt any service can magically get you to the front of the line. Sounds like you're selling something.

•It's not magic - they use technology that navigates the IRS phone system for you and holds your place in line. When they reach a live agent, they call you and connect you directly to that agent. You don't have to stay on the phone listening to hold music for hours. The IRS phone system actually allows for this - Claimyr just automates the waiting process so you don't have to. It's completely legitimate and they're not doing anything special that gets preferential treatment. They're just handling the frustrating hold time part so you don't have to keep redialing when you get disconnected.

I need to eat my words and apologize for my skepticism about Claimyr. After posting that comment, I decided to try it myself since I've been trying to reach the IRS about my retirement plan questions for weeks. I was absolutely shocked when I got a call back in about 20 minutes connecting me to an actual IRS representative. They answered all my questions about the IRA deduction limits with a 401k and even emailed me Publication 590-A which has the full breakdown of the phase-out calculations. The agent explained that these limits are often misunderstood because most financial websites focus on the contribution limits rather than the deduction limits. For anyone dealing with this specific issue, ask them to explain the "retirement plan at work" rules for IRA deductions - they're super helpful once you actually reach them.

To add to what others have said, I found the official info on this in IRS Publication 590-A. The section you want is called "How Much Can You Deduct" and specifically look for the part about "If You Are Covered by a Retirement Plan at Work." Basically, when you check that box on your tax return that says you're covered by a retirement plan at work (which you are since you contribute to a 401k), those lower MAGI limits kick in. For 2025 those limits are: - Single: phaseout from $77,000-$87,000 - Married filing jointly: phaseout from $123,000-$143,000 - Married filing separately: phaseout from $0-$10,000 (this one is brutal!) Inside the phaseout range, you calculate a partial deduction. Above the range, no deduction. Remember though, you can still MAKE the $7000 contribution - it just won't be deductible. This is where backdoor Roth strategies come in handy.

•Thank you! This is exactly what I was looking for. So my original confusion makes sense - there's the contribution limit ($7000) which is what most sites talk about, and then there's the deduction limit based on MAGI which is much lower when you have a workplace plan. Do you know where in the tax form this gets reported? Is there a specific worksheet for calculating the partial deduction in the phaseout range?

•You're welcome! Yes, that's the exact distinction that trips up so many people. The $7000 is just how much you can put in, not necessarily how much you can deduct. For calculating the partial deduction in the phaseout range, there's a worksheet in Publication 590-A called the "IRA Deduction Worksheet." Most tax software will do this calculation automatically, but if you want to do it yourself, that's where to find it. Basically you determine what percentage of the phaseout range you fall in, and then reduce your maximum deduction by that percentage. On your tax form, the IRA deduction goes on Schedule 1, Line 20 of Form 1040 (though line numbers sometimes change year to year). The calculation itself doesn't appear on the form - just the final deduction amount.

One thing nobody has mentioned yet is that you might want to consider a Roth IRA instead if you're in the phaseout range for traditional IRA deductions. Since Roth contributions aren't deductible anyway, the fact that you have a 401k doesn't matter for Roth eligibility. The income limits for Roth contributions are much higher: - Single: phaseout from $146,000-$161,000 - Married filing jointly: phaseout from $230,000-$240,000 So if you're in that weird middle zone where you make too much to deduct traditional IRA contributions because of your 401k, but not enough to be excluded from Roth contributions, the Roth is often the better choice.

•This is what I do! I'm exactly in that zone where I can't deduct traditional IRA contributions but can still contribute to a Roth. The math works out better in the long run anyway assuming tax rates stay similar or go up.

•That's great! You've found the sweet spot. For many people in this income range, the Roth often makes more mathematical sense anyway - especially if you believe tax rates will be higher in the future than they are now. Another advantage is that Roth IRAs don't have Required Minimum Distributions (RMDs) like traditional IRAs do, so they give you more flexibility in retirement for managing your tax situation.

This thread has been incredibly helpful! I've been dealing with this exact same confusion for months. I contribute to my employer's 401k and was shocked when my tax software reduced my IRA deduction so dramatically. What really clarifies things is understanding that there are THREE different sets of limits at play here: 1. IRA contribution limits ($7,000 for 2025) 2. IRA deduction limits when you have a workplace plan (much lower MAGI thresholds) 3. Roth IRA contribution limits (higher MAGI thresholds) I think the confusion comes from most financial websites and articles only talking about #1, when what most people actually care about is #2 - whether they can get the tax deduction. For anyone else reading this: if you have a 401k at work and make decent money, you're probably better off with a Roth IRA since you likely won't get much (or any) deduction from a traditional IRA anyway. The tax-free growth of the Roth often wins out mathematically in that situation. Thanks everyone for breaking this down so clearly!

•Exactly! You've summarized this perfectly. Those three different sets of limits are what make this so confusing, and most people (including myself until recently) don't realize they exist separately. I was in the same boat - contributing to both my 401k and traditional IRA thinking I'd get full deductions on both, only to discover during tax prep that my IRA deduction was severely limited because of my income and workplace plan participation. Your point about the Roth IRA being better in this situation is spot on. Once you're in that income range where traditional IRA deductions are phased out but Roth contributions are still allowed, the math usually favors the Roth - especially if you're young and have decades for that tax-free growth to compound. It's also worth noting that even if you're above the Roth income limits, you can still do the "backdoor Roth" conversion that others mentioned, where you contribute to a non-deductible traditional IRA and immediately convert it to Roth.
