Can I claim IRA and 401k deductions on my 2025 tax form 1040?
I'm in the process of trying to file my taxes for 2025 and I'm completely confused about retirement deductions. My employer offers a 401k where they match up to 5% of what I put in. I've been contributing consistently throughout the year. The thing I can't figure out is whether I can put these 401k contributions somewhere on my tax forms as a deduction? If I can deduct them, what specific form do I need to complete? I've been watching tons of YouTube videos and searching Google but I'm getting really contradictory information about whether I can claim this and what forms I need to fill out. Some sources say I can deduct my contributions on my 1040 form, others say the contributions are already pre-tax so I don't need to do anything. I'm totally lost at this point. Can someone please clarify? Thanks in advance for any help!

The confusion you're experiencing is pretty common. Let me help clear things up! For your employer-sponsored 401k, the contributions you make through payroll are already excluded from your taxable income on your W-2. If you look at Box 1 of your W-2, you'll notice the amount shown is already reduced by your 401k contributions. This means you don't need to take an additional deduction for these contributions on your tax return. However, if you also contributed to a traditional IRA separate from your 401k, that's where Form 1040 deductions come into play. You would report traditional IRA contributions on Schedule 1, Line 20. Keep in mind that your ability to deduct IRA contributions may be limited if you participate in a workplace retirement plan (like your 401k), depending on your income level.

•Thanks for explaining that. So if I understand correctly, my 401k contributions are already accounted for in my W-2 Box 1 amount, meaning the IRS already knows about them? Does this mean I don't need to do anything extra regarding my 401k when filing? Also, I did put about $2,500 in a traditional IRA this year separate from my 401k. So for that amount, I would need to fill out Schedule 1, Line 20? Are there income limits I should be aware of?

•Yes, you're understanding correctly. Your 401k contributions are already handled through your payroll and reflected in your W-2, so no additional reporting is needed for those. For your traditional IRA contribution of $2,500, you'll report that on Schedule 1, Line 20. And yes, there are income limits for deducting IRA contributions when you have a workplace retirement plan. For 2025, if you're single, the deduction begins to phase out at a modified adjusted gross income (MAGI) of $78,000 and is eliminated at $88,000. If you're married filing jointly, the phase-out range is between $129,000 and $149,000. If your income is below these thresholds, you can take the full deduction.

After struggling with the same exact confusion last year, I finally found a solution that saved me HOURS of research. I started using taxr.ai (https://taxr.ai) to help me figure out my retirement deductions. You literally just upload your tax documents and it analyzes everything to tell you exactly what deductions you qualify for. I was able to figure out my 401k and IRA situation in minutes instead of the days I spent searching online.

•Does it actually tell you which forms to fill out and where to put the numbers? I'm using TurboTax but it keeps asking me questions about my IRA that I don't understand.

•I'm a bit skeptical about these tax services. How does it compare to something like TurboTax or H&R Block? Does it actually file your taxes or just give advice? And how secure is it to upload all my financial documents?

•It actually guides you through exactly which forms you need and where specific numbers should go. I had the same issue with TurboTax asking confusing questions, but taxr.ai broke it down so I knew exactly how to answer them. Yes, it's different from TurboTax or H&R Block because it's more focused on document analysis rather than filing. It helps you understand your tax situation before you file. As for security, they use bank-level encryption and don't store your documents after analysis. I was hesitant too but after reading about their security measures I felt comfortable using it.

Just wanted to follow up - I tried taxr.ai after seeing this thread and it was super helpful! I uploaded my W-2 and some 401k statements and it immediately identified that I had been making pre-tax contributions that were already accounted for in my W-2. But it also pointed out that I could make an IRA contribution for 2025 until the tax filing deadline in April 2026 and still get a deduction for it. I had no idea about that timing flexibility! Ended up making an additional contribution and saving about $650 in taxes. Definitely worth checking out if you're confused about retirement deductions like I was.

If you're having trouble getting clear answers about IRA deductions, you might need to speak directly with the IRS. I was in a similar situation and spent WEEKS trying to get through to someone. Finally found https://claimyr.com which got me connected to an actual IRS agent in under 20 minutes instead of waiting on hold for hours. There's a demo video of how it works here: https://youtu.be/_kiP6q8DX5c. The agent I spoke with cleared up my confusion immediately and confirmed exactly which lines on my 1040 needed to include my IRA information.

•How does this service actually work? Do they somehow get you to the front of the IRS phone queue? I've tried calling multiple times and always hang up after being on hold for 45+ minutes.

•Yeah right. No way this actually works. The IRS phone system is designed to be impossible to navigate. I'll believe it when I see it. Sounds like just another service trying to make money off people's tax frustrations.

•They use a system that continuously calls the IRS and navigates the phone tree for you. Then when an agent is about to answer, they connect the call to your phone so you don't waste time waiting on hold. I was super skeptical too before trying it. I had spent over 3 hours on hold the previous week and never got through. I honestly didn't think it would work either, but I was desperate for answers about my IRA deductions. The service called me back in about 15 minutes and suddenly I was talking to an actual IRS representative. They don't guarantee a specific wait time since it depends on IRS call volume, but it was way better than doing it myself.

I need to eat my words. After dismissing that Claimyr service as BS, I decided to try it out of pure frustration after spending 2+ hours on hold with the IRS yesterday. I got connected to an IRS agent in about 25 minutes and got definitive answers about my IRA deduction questions. The agent confirmed that since I participate in my employer's 401k, my traditional IRA deduction is limited based on my income (which in my case meant a partial deduction). They walked me through exactly which line items to use on the 1040 and Schedule 1. Totally worth it just to get clear, authoritative information directly from the source instead of trying to interpret conflicting advice online.

To add to what others have said, your 401k contributions through your employer come in two forms that are treated differently: 1) Traditional 401k contributions are pre-tax, meaning they already reduce your taxable income on your W-2, Box 1. 2) Roth 401k contributions (if you have this option) are after-tax, so they don't reduce your current year's taxable income. For your separate IRA contributions, here's a quick reference: - Traditional IRA: potentially deductible on Schedule 1, Line 20 (subject to income limits if you have a workplace plan) - Roth IRA: not deductible, but grows tax-free (also has income limits for contribution eligibility

•Wait, I'm confused about the Roth vs Traditional options. I thought Roth was always better because you don't pay taxes when you withdraw in retirement? Why would anyone choose Traditional?

•Traditional vs Roth is about when you pay taxes, not if you pay taxes. With Traditional accounts, you get a tax break now (lower current taxes) but pay taxes when you withdraw in retirement. With Roth, you pay taxes now but get tax-free withdrawals in retirement. Traditional makes more sense if you expect to be in a lower tax bracket in retirement than you are now. For example, if you're in your peak earning years, you might benefit more from the immediate tax deduction. Roth makes more sense if you expect to be in the same or higher tax bracket in retirement, or if you want the flexibility of tax-free withdrawals later.

Does anyone know if there's still time to make an IRA contribution for 2025? I haven't started my taxes yet but I'd like to reduce my tax bill if possible.

•Yes! You can make IRA contributions for 2025 all the way up until the tax filing deadline in April 2026 (usually April 15th, but it can shift depending on weekends/holidays). Just make sure you specify to your IRA provider that the contribution is for tax year 2025.

This is such a helpful thread! I was in the exact same boat last year trying to figure out the difference between 401k and IRA deductions. One thing that really helped me was keeping track of all my retirement contributions throughout the year in a simple spreadsheet. I record my 401k contributions from each paycheck (which I can see on my pay stub) and any separate IRA contributions I make. When tax time comes around, I can quickly reference this to see what I contributed where. For your 401k, you're right that it's already handled through payroll - you'll see the total amount in Box 12 of your W-2 with code "D" for traditional 401k contributions or "AA" for Roth. But like others mentioned, the traditional contributions already reduced your taxable income in Box 1, so no additional deduction needed. For your $2,500 IRA contribution, definitely check those income limits Sofia mentioned before claiming the deduction. If you're close to the phase-out ranges, you might want to consider making it a Roth IRA contribution instead since those don't have the same deduction restrictions (though they do have income limits for eligibility).

•That spreadsheet idea is brilliant! I wish I had thought of that earlier in the year. I've been scrambling to piece together all my contribution amounts from different sources. Quick question about the W-2 codes you mentioned - I'm looking at my W-2 now and I see Box 12 has code "D" with an amount, but I also see code "E" listed. Do you know what code "E" represents? I want to make sure I'm understanding all the retirement-related entries on my W-2 correctly before I finish filing. Also, regarding the Roth vs Traditional IRA decision for that $2,500 - is there a deadline to decide which type of contribution it should be, or can I change it after I make the contribution?

•Great question about the W-2 codes! Code "E" in Box 12 represents employer contributions to a Section 457(b) deferred compensation plan, which is typically offered by government and some non-profit employers. This is separate from your 401(k) contributions and represents money your employer contributed on your behalf - similar to how employer 401(k) matching works. Regarding your $2,500 IRA contribution timing question - you typically need to specify whether it's Traditional or Roth when you make the contribution to your IRA provider. However, you do have some flexibility! You can recharacterize (convert) a Traditional IRA contribution to Roth, or vice versa, up until the tax filing deadline (including extensions). So if you made it as Traditional but realize Roth would be better after checking those income limits, you can still change it. Just contact your IRA provider and request a "recharacterization" - they'll handle the paperwork. Keep in mind that if you recharacterize from Traditional to Roth, you'll lose the tax deduction but gain the tax-free growth benefit for retirement.
