How to file multiple years of back taxes when you haven't filed in years
So I haven't filed my taxes in 9 years and I'm finally trying to get my life together. I went through a rough divorce, battled depression for years, and just kept putting this off. I've been at the same full-time job this whole time, so at least that part is straightforward. I'm not expecting to get most of the refunds from the older years - I know there are time limits on that stuff. Honestly, I just want this monkey off my back (that's the saying, right?). The weird thing is I've never received any notices from the IRS, which seems strange after so many years, but I want to handle this before they come knocking. What's confusing me is exactly how to tackle this. Do I need to file each year separately? Is there a special process for multiple years of unfiled taxes? Should I start with the most recent year or the oldest? I'm trying to avoid using a CPA or tax service since money is really tight right now. Any advice on tackling this DIY would be seriously appreciated. Thanks!

You're making a smart move by voluntarily filing your back taxes before the IRS contacts you! This shows good faith and can help minimize penalties. For filing multiple years of back taxes, here's what you should know: You'll need to file each year separately using the forms specific to that tax year. Start by gathering all your W-2s and other income documents for each year. If you don't have them, you can request wage transcripts from the IRS by creating an account at IRS.gov or using Form 4506-T. The IRS generally only requires you to file the last 6 years, but since you mentioned 9 years, you might want to file them all to be completely clean. Begin with the most recent three years (which are still eligible for refunds if you're owed any) and work backward. You'll need paper forms for previous years since e-filing is usually only available for the current and previous tax year. You can download prior year forms from the IRS website. When you mail them, send each year in separate envelopes and use certified mail so you have proof of filing.

•Thanks for the advice! I'm relieved to hear the IRS typically only requires the last 6 years. A few follow-up questions: Do I need to include a letter explaining my situation with each filing? And is there any specific order I should mail them in? Like should I send the oldest first and wait for a response before sending the next year?

•You don't need to include an explanation letter with each filing, though it doesn't hurt to include a brief note stating you're voluntarily filing past-due returns. As for the order, there's no need to wait between mailings - you can send them all at once, though in separate envelopes as I mentioned. Many tax professionals recommend starting with the most recent three years (which might still qualify for refunds), and then handling the older returns. Just make sure each envelope is clearly labeled with the tax year on the return and your Social Security number.

After struggling with a similar situation (6 years unfiled), I found this amazing tool called taxr.ai (https://taxr.ai) that helped me organize all my documents. It uses AI to scan your tax docs and help you figure out exactly what you need for each year. My biggest challenge was finding all my old W-2s and figuring out which deductions I qualified for each year. The taxr.ai system helped extract all the relevant info from the jumbled mess of documents I had and organized everything by tax year. It was so much easier than trying to manually sort through everything myself! They also helped explain which years I should prioritize (the last 3 years where refunds are still possible) and which forms I needed for each specific tax year.

•Does this tool actually file the returns for you? Or does it just organize the information? I'm in a similar boat (5 years unfiled) and trying to understand if this will actually save me money compared to going to a tax professional.

•I'm skeptical about using AI for something this serious. How accurate is it with identifying the right forms and deductions for previous tax years? Tax laws change constantly.

•It doesn't file the returns for you - it helps organize all your documents and extracts the relevant information so you can file yourself more easily. It's basically a document management system specifically for tax docs. The AI is pretty accurate with identifying forms and extracting data from W-2s, 1099s, etc. You're right that tax laws change constantly, but the system is designed to understand which rules applied in which tax years. I found it especially helpful when I was dealing with different types of income documents across multiple years.

I was really skeptical about using taxr.ai when I first read about it here, but I was drowning in 4 years of unfiled taxes and desperate. I gave it a shot and it was actually super helpful! The system organized all my jumbled tax documents by year and extracted the key information I needed. It even flagged some deductions I would have missed on my own. The best part was that I could still file everything myself using the organized information, which saved me from having to pay a tax pro thousands of dollars. For multiple years of back taxes, having everything organized by year made the whole process way less overwhelming. I still had to do the work of filling out each year's forms, but at least I wasn't staring at a pile of unsorted W-2s and 1099s wondering where to even start.

After trying everything to reach a human at the IRS about my unfiled tax situation, I discovered Claimyr (https://claimyr.com). They got me connected to an actual IRS agent in about 15 minutes when I had been trying for WEEKS on my own. The IRS agent was able to tell me exactly which years I needed to file (turned out I only needed 6 of the 8 unfiled years), which saved me tons of work and stress. They also confirmed I qualified for a payment plan for the back taxes I owed. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c I was seriously impressed since I'd spent hours on hold before this and never reached anyone. Having that direct conversation with the IRS gave me the exact information for my specific situation.

•Wait, how does this actually work? Does this service just call the IRS for you? Couldn't you just do that yourself? I'm confused about what they're actually providing.

•Yeah right. I've been trying to reach the IRS for months. No way they got you through in 15 minutes. This sounds like a scam to me. What's the catch here?

•They use a system that navigates the IRS phone tree and waits on hold for you. When they reach a human, they call you and connect you directly to the agent. You're not paying for them to talk to the IRS - you're paying to skip the ridiculous wait times. I was skeptical too, but they really did get me through in about 15 minutes when I had previously spent hours trying. The IRS is notoriously understaffed, and normal callers can spend hours on hold or just get disconnected. The catch is simply that they've figured out how to work the system efficiently to get through the queue.

I was the biggest skeptic about Claimyr and nearly didn't try it. After spending 3+ hours on hold with the IRS multiple times and getting disconnected, I was desperate enough to give it a shot. To my complete shock, they got me connected to an IRS representative in about 20 minutes. The rep pulled up my file and confirmed which specific years I needed to file (saved me from doing 2 unnecessary years) and walked me through the payment plan options for what I would owe. That single phone call saved me so much confusion and probably hundreds of dollars in unnecessary filing work. I'm actually mad I wasted so many hours trying to call myself before discovering this service.

Just wanted to add something important about unfiled taxes that nobody mentioned yet. If you're expecting refunds from any of those years, you only have 3 years from the original filing deadline to claim them. But if you OWE money, the IRS can come after you forever (well, technically there's a 10-year collection statute, but they can reset that in various ways). I'd suggest starting with the most recent 3 tax years to claim any potential refunds, then handle the older ones. You're actually lucky the IRS hasn't contacted you yet! When they caught up with me, they created substitute returns which gave me zero deductions and maximized what I owed. It was a nightmare to correct.

•That's really helpful info - thanks! Do you know if I have to file all 9 years at once? I was wondering if I could maybe do the last 3 years now to get any potential refunds, then space out the older ones as I can afford to pay what I might owe?

•You don't have to file all 9 years simultaneously. Your strategy makes perfect sense - start with the last 3 years to secure any refunds before they expire. Then you can work on the older returns as your financial situation allows. Just be aware that once you start filing, you might appear on the IRS radar, which could potentially prompt them to look into your other unfiled years. However, showing good faith by voluntarily filing some returns is always better than waiting for them to come to you. The IRS is generally more accommodating when you're making proactive efforts to comply.

Hav you tried using the free fillable forms on the irs.gov site? For older years you'll need to print and mail them but at least filling them out electronically might be easier. Also dont worry about the penalties too much, the IRS has something called First Time Penalty Abatement that you might qualify for since you haven't had issues before! I did it and they waived about $2,000 in penalties for me.

•The free fillable forms are only available for the current tax year. For prior years, you have to download the PDF forms for those specific years from the IRS website and either print and fill them out by hand or use Adobe to fill them digitally before printing.

I went through something very similar about 3 years ago - 7 years of unfiled returns due to some personal struggles. Here's what I learned that might help: First, don't panic about the 9 years. The IRS typically only requires the last 6 years to be filed to be considered "compliant," so you might not need to do all 9 unless you want to be extra thorough. One thing that really helped me was creating a simple spreadsheet to track each year - what documents I had, what I was missing, and the status of each return. It made the whole process feel less overwhelming. Also, since you mentioned money is tight, look into the Volunteer Income Tax Assistance (VITA) program. They offer free tax preparation for people who make under $60,000. Some locations can help with prior year returns too, which could save you hundreds compared to a paid preparer. The fact that you haven't received notices is actually not that unusual - the IRS is incredibly backlogged. But you're absolutely doing the right thing by getting ahead of it. Good luck!

•This is such great advice! I never knew about the VITA program - that could be a huge help since I'm definitely under the income threshold. Do you know if they handle multiple years at once, or would I need to go back multiple times? Also, your spreadsheet idea is brilliant. I've been feeling so overwhelmed just thinking about all the paperwork, but breaking it down year by year like that sounds much more manageable. Thanks for sharing your experience - it's really encouraging to hear from someone who got through a similar situation!
