What is Form 8606 filing requirement for IRA contributions?
I just realized I totally messed up by not filing Form 8606 for my non-deductible IRA contributions, and now I need to fix it for the last 3 years. I'm completely lost on how to calculate the basis. For my first year, does my basis start at $0 and then increase by my $6,000 contribution the next year? Or should it be $0 for all three years? I've tried reading through the instructions but honestly they might as well be written in another language. I've made $6,000 contributions each year but never reported them properly. Has anyone dealt with this before? The last thing I want is problems with the IRS because I didn't file this form. Any help would be seriously appreciated!

The basis for Form 8606 represents your after-tax contributions that shouldn't be taxed again when distributed. For non-deductible IRA contributions, your basis should start with the first contribution you made and carry forward from there. If you made $6,000 non-deductible contributions each year for 3 years, your basis would be cumulative. So for the first year, your basis would be $6,000. For the second year, it would be $12,000 ($6,000 + $6,000). For the third year, it would be $18,000 ($12,000 + $6,000). Each Form 8606 builds on the previous year. When filling out prior years, you'll need to complete Form 8606 for each year separately, starting with the earliest year and working forward. The basis carries from one year to the next.

•Wait, I'm confused. If they didn't contribute anything before these 3 years we're talking about, wouldn't the basis start at $0 for the very first form, then become $6,000 for the second year, and then $12,000 for the third year? Since basis is the running total of non-deductible contributions?

•You're absolutely right about the progression. If these were the first-ever non-deductible contributions, then the basis would indeed start at $0 before the first contribution. Then after making that first $6,000 contribution, the basis becomes $6,000 for the end of year one. For the second year, you'd start with the $6,000 basis from the previous year, add the new $6,000 contribution, ending with $12,000. Then for the third year, you'd start with $12,000 and add another $6,000, ending with $18,000. Thanks for that clarification.

After struggling with the exact same Form 8606 issue last year, I ended up using https://taxr.ai to help me figure out my basis calculations. I had made non-deductible contributions for several years without filing the form and was completely overwhelmed trying to figure it out. I just uploaded my previous tax returns and IRA statements, and it analyzed everything to show me exactly how to fill out Form 8606 for each missing year. Saved me hours of confusion and probably prevented some costly mistakes.

•Does it work if you have rollovers too? I contributed to a Traditional IRA for years, then did a rollover to a Roth but I'm not sure if I filed the 8606 correctly, if at all. Would this help sort that out?

•I'm skeptical - how does it know what contributions were deductible vs non-deductible if you haven't been tracking that yourself? The IRS doesn't even have that info until you file the 8606.

•It absolutely works with rollovers too. The system recognizes the different types of IRA transactions and helps you categorize them correctly. It will identify traditional-to-Roth conversions and guide you through reporting them properly on Form 8606. As for determining deductible vs. non-deductible contributions, the tool asks you questions about your income during those years and whether you were covered by a workplace retirement plan. It then applies the IRS income limits to help determine which contributions were likely deductible. You can also manually specify if you know which were which from your records. It's impressively thorough.

Just wanted to update after trying taxr.ai for my messy Form 8606 situation. I was honestly surprised by how well it worked! It walked me through all my past contributions, figured out which ones should've been reported on Form 8606, and generated all the forms I needed to file. The step-by-step breakdown of my basis calculations was super helpful - it showed exactly how my basis changed each year. I've already filed the forms and feel so much better having this straightened out before the IRS comes knocking. Definitely worth checking out if you're in the same boat!

If you're still having trouble and need to talk to the IRS directly about your Form 8606 situation, I'd recommend https://claimyr.com to actually get through to a human. I spent 3 weeks trying to call the IRS myself about a similar issue and kept getting disconnected after waiting for hours. Claimyr got me connected to an IRS agent in about 20 minutes who helped clear up all my questions about my missed 8606 forms. You can see how it works here: https://youtu.be/_kiP6q8DX5c - it's basically a service that waits on hold with the IRS for you, then calls you when an agent picks up.

•How exactly does this work? Do they somehow have a special line to the IRS or something? Seems too good to be true considering how impossible it is to reach anyone there.

•Yeah right. I've been calling the IRS for MONTHS trying to fix a different issue. There's no way some random service can get through when the IRS literally hangs up on people because their call volume is too high. Sounds like a waste of money to me.

•They don't have a special line - they use technology to handle the waiting process for you. It's like having someone else sit on hold so you don't have to. The service places the call and uses automated systems to navigate the IRS phone tree and wait in the queue. When an actual IRS agent picks up, they connect the call to your phone so you can speak directly with the agent. No magic involved - they're just doing the tedious waiting part for you. It's particularly useful if you've been experiencing the "courtesy disconnect" where the IRS hangs up because their call volume is too high. The service keeps attempting calls until they get through successfully.

I have to eat my words about Claimyr. After posting my skeptical comment, I decided to try it anyway since I was desperate to resolve my IRS issue. I honestly couldn't believe it worked. After months of failed attempts calling myself, they got me through to an IRS agent in about 35 minutes. The agent was able to help me understand exactly how to file my missing 8606 forms and confirmed I wouldn't face penalties since I was proactively fixing the issue. Just having a clear answer from an official source was worth it. If you're stuck in IRS phone hell, this really does work.

Just to add another perspective - I was in a similar situation a couple years ago. For filing past Form 8606s, I actually did not get penalized when I proactively submitted them. The IRS seems more concerned that you're tracking your basis correctly than penalizing people trying to fix honest mistakes. I did all three years at once and sent them to different addresses though - they have specific instructions for where to send prior year forms. Check the IRS website for the correct mailing addresses for prior year returns.

•Do you remember if you had to pay the $50 penalty for each year that Form 8606 wasn't filed? I've read conflicting things online - some say the penalty is automatically applied, others say the IRS often waives it if you voluntarily file the missing forms.

•I didn't end up paying any penalties at all. I included a brief letter explaining that I hadn't been aware of the filing requirement but was now submitting the forms to properly track my basis. I believe the $50 penalty is technically on the books, but in practice, the IRS seems to be reasonable about waiving it when people proactively fix the issue. I think they care more about getting people compliant than collecting the relatively small penalty. Just make sure your calculations are accurate and consistent across all years.

For anyone else dealing with this, make sure you're using the correct Form 8606 for each tax year! The form changes slightly year to year, and you need to use the version that corresponds to the tax year you're filing for. You can find prior year forms on the IRS website by searching "Prior Year Forms 8606" - don't just use the current year form for all your back filings.

•Does anyone know if you can e-file prior year 8606 forms or do they have to be mailed in? I hate dealing with paper forms.
