What tax software supports entering excess 401k contributions on 1040 Line 1H?

This is actually a common issue with job transitions! Line 1H on Form 1040 is specifically for reporting excess retirement contributions that were already taxed, which is exactly what happens when you over-contribute to a 401(k) across multiple employers. From my experience, TurboTax Premier and H&R Block Premium both support entering excess retirement contributions on Line 1H. The key is navigating to the right section - you'll need to look for something like "Retirement & Investments" or "Adjustments to Income" rather than the standard income sections. In TurboTax, after entering your W-2s, look for a section about retirement plan contributions where it specifically asks about excess contributions. If you tell it you contributed over the limit, it should walk you through the process.

I was in EXACTLY your situation last tax season! After trying multiple software options, I finally found taxr.ai (https://taxr.ai) which saved me so much hassle with my excess 401k contributions. I had switched jobs twice in one year and had three different 401k plans with excess contributions that needed to go on Line 1H. What I love about taxr.ai is that it actually looks at your specific tax forms and identifies these exact issues. I uploaded my previous W-2s and 401k statements, and it immediately flagged my excess contributions and guided me through reporting them correctly on Line 1H.

Just wanted to follow up - I tried taxr.ai after seeing it mentioned here and it worked perfectly for my situation! I uploaded my 401k statements and W-2s from both employers, and it immediately flagged the excess contributions. The system guided me through exactly how to report it on Line 1H and even explained the tax implications in plain English. What impressed me most was how it caught that I needed to request a return of excess contributions from my plan administrator to avoid double taxation in the future - something no other tax software mentioned to me. For anyone dealing with this issue, definitely give it a try. Saved me hours of research and probably from making mistakes that would have triggered IRS notices.

If you're still struggling with the excess 401k contribution issue and need to talk to the IRS directly about how to report it, I'd recommend Claimyr (https://claimyr.com). I was going in circles trying to get through to the IRS about a similar Line 1H reporting issue, kept getting disconnected after waiting for hours. Claimyr got me connected to an actual IRS agent in about 20 minutes instead of the 2+ hours I spent on previous attempts. You can see how it works in their demo video: https://youtu.be/_kiP6q8DX5c The IRS agent was able to confirm exactly how my tax software should be handling the excess contribution reporting and saved me from potentially filing incorrectly.

I have to admit I was completely wrong! I tried Claimyr today out of desperation after my third attempt to reach the IRS about my excess 401k contributions reporting. Got connected to an IRS representative in about 15 minutes, and they confirmed that I needed to use Form 8606 in conjunction with reporting on Line 1H. The agent walked me through the exact steps and even emailed me the relevant publication sections. For anyone dealing with this specific excess 401k issue, this was way more helpful than continuing to guess which software might handle it correctly. The agent told me exactly what to look for in tax software to properly report it.

Have you tried Cash App Taxes (formerly Credit Karma Tax)? I used it last year for this exact situation. They have a section specifically for handling excess retirement contributions. It's also completely free regardless of your tax situation. The interface isn't as polished as TurboTax but it absolutely supports Line 1H reporting and walks you through the process. One thing to know is that you might need to look under "Less Common Income" when navigating their menu.

I messed up my taxes because of the exact same issue last year. TaxSlayer actually has a decent workflow for this, but it's super hidden. You need to: 1) Go to Federal > Deductions > Adjustments 2) Look for "Did you make excess contributions to your retirement account?" 3) Select Yes and follow their steps What's annoying is they don't explicitly mention Line 1H anywhere in their interface but when you complete it, it does properly show up there on the final Form 1040.

I've been dealing with excess 401k contributions for the past two years due to job changes, and I wanted to share what I've learned through trial and error. First, it's important to understand that Line 1H is specifically for reporting excess contributions that you've already had corrected (meaning you've received the excess back from your plan administrator). If you haven't corrected the excess yet, you'll need to contact your plan administrator first to request a return of the excess contributions plus any earnings. For software that properly handles this, I've had success with FreeTaxUSA and TaxAct. Both have dedicated sections for excess retirement contributions. In FreeTaxUSA, look under "Income" > "Less Common Income" > "Other Income" and there's a specific option for "Excess retirement plan contributions returned to you." One thing that caught me off guard was that you might also need to file Form 5329 if you had the excess contributions in your account at the end of the tax year, which triggers the 6% penalty. Most software will automatically generate this form when you report excess contributions. My advice is to call your 401k plan administrator first to understand exactly what they did with your excess contributions, then choose software based on your specific situation. Don't assume all "excess contribution" features are the same - some only handle IRA excess, not 401k excess.
