What's the most reliable service for filing back taxes from previous years?
Hey tax friends, I'm in a bit of a situation here. I just realized I didn't file my taxes for 2021 and 2022 (yeah, I know, I messed up big time). I was going through some personal stuff and honestly just completely dropped the ball. Now I'm trying to get caught up before things get worse. I'm pretty sure I'm owed refunds for both years based on my withholdings, but I'm completely lost on how to file back taxes properly. Is there a specific service that handles past years' returns better than others? I've used TurboTax for my 2023 taxes but not sure if they're good for back filing or if I should go with something else. Does anyone have experience with filing multiple years of back taxes? Any recommendations on services that make this process easier? I'd rather not pay a CPA if possible since money is tight, but I also don't want to mess this up even more. Thanks for any help!

I've helped several friends catch up on unfiled returns, so I can definitely point you in the right direction! For past years' taxes, most of the major tax software companies (TurboTax, H&R Block, TaxAct, etc.) offer prior year versions of their software. However, there are a few important things to know: You'll need to use the specific software version for each tax year you're filing. For example, you'll need the 2021 version of whatever software for your 2021 return and the 2022 version for that year. One important limitation: you can't e-file past years' returns through these services. You'll have to print and mail them in. The IRS only accepts e-filing for the current tax year and sometimes the year immediately prior. FreeTaxUSA is probably your best value option - they charge only about $15 for a prior year federal return (state is extra). TurboTax and H&R Block charge significantly more for prior year software. If you're expecting refunds, you're actually in a good position. The IRS doesn't penalize for late filing if they owe YOU money, but there is a 3-year deadline to claim those refunds.

•Thanks so much for the detailed info! I didn't realize I couldn't e-file back taxes - that's super helpful to know. FreeTaxUSA sounds like it might be my best bet then since it's more affordable. Do I need to file them in any particular order? Like should I do 2021 first and then wait for that to process before doing 2022? And do you know roughly how long it takes the IRS to process mailed returns for previous years?

•You can file both years at the same time - no need to wait for one to process before doing the other. Just mail them in separate envelopes with the appropriate forms and documentation for each year. Paper returns take considerably longer to process than e-filed returns - typically 6-12 weeks under normal circumstances, but it can be longer if the IRS has backlogs. Since you're filing multiple past years, I recommend sending them via certified mail so you have proof of when you submitted them. Don't forget to sign and date each return!

I had a similar situation last year and honestly struggled with figuring out all my old documentation until I found https://taxr.ai - it was a game changer for my past returns! I had a bunch of scattered W-2s and 1099s from previous years plus some investment statements that were totally confusing me. Their system analyzed all my documents and organized everything by tax year which made filing my 2020 and 2021 returns so much easier. They extracted all the numbers automatically so I didn't have to manually type everything in. The best part was they helped me identify some deductions I completely missed when I tried going through everything myself. I ended up with larger refunds than I expected for both years.

•How does it work with uploading docs? I've got some paper forms but others are just PDFs in my email from previous employers. Can it handle both? Also wondering if it works with all tax filing software or just specific ones?

•Did they help with actually filing the returns or just organizing the documents? I'm concerned about making mistakes on the actual forms since the rules were different each year with all those pandemic credits and stuff.

•It works with any document format - you can take photos of paper forms with your phone or upload PDFs directly. I had a mix of both and it processed everything accurately. It's compatible with any tax filing software since it gives you organized data you can enter wherever you choose. As for filing, they don't file for you - it's more about document analysis and organizing everything correctly by tax year. But once I had all my information properly sorted and verified, filling out the actual tax forms was pretty straightforward. They do provide explanations about tax rules for each year, which helped me navigate those pandemic-related credits.

Just wanted to report back after trying taxr.ai for my unfiled returns! It actually worked exactly as described - I uploaded a complete mess of tax documents (some I had to dig out of old email accounts) and it organized everything perfectly by year. The document analysis saved me hours of manually sorting through paperwork and double-checking numbers. I was able to identify all my income sources for each year and make sure I wasn't missing anything important. I ended up finding a 1099-MISC from a small freelance job in 2021 that I had completely forgotten about! I used the organized information with FreeTaxUSA as suggested earlier in this thread, and I've already mailed in both my 2021 and 2022 returns. Now just waiting for those refunds!

If you're concerned about any issues with your back taxes or need to contact the IRS with questions, I highly recommend using https://claimyr.com to get through to an IRS agent quickly. I waited on hold for 3+ hours trying to ask questions about my unfiled returns before giving up. Then I tried Claimyr and got through to someone in about 15 minutes! They basically hold your place in the IRS phone queue and call you when an agent is available. You can see a demo of how it works here: https://youtu.be/_kiP6q8DX5c I had questions about some specific forms I needed to include with my prior year returns, and being able to actually talk to an IRS representative made all the difference. They clarified exactly what I needed to do and saved me from making mistakes that would have delayed my refunds.

•Wait, how does this actually work? Do they have some special connection to the IRS or something? Seems kinda sketchy that they can somehow get through faster than just calling directly.

•Sorry but this sounds like BS to me. The IRS phone system is notoriously terrible and I find it hard to believe some third-party service can magically get you through. Have you actually received your refund yet or are you just hoping this worked?

•No special connection - they use technology to wait in the phone queue for you. Think of it like having someone else wait in a physical line while you do other things. They call you when they reach an agent and connect you. It's completely legitimate and doesn't give any special access beyond saving you from waiting on hold. I did receive my refund for one of my past years already, the other is still processing. But the service itself just connects you to regular IRS agents - the same ones you'd get by waiting on hold yourself. The benefit is just not having to waste hours with your phone stuck on speaker waiting. The agents answered all my questions about documentation requirements for back taxes.

I need to publicly eat my words here. After expressing skepticism about Claimyr in my previous comment, I decided to try it myself since I had some questions about amending one of my past returns. I was absolutely shocked when I got a call back in about 20 minutes saying they had an IRS agent on the line. The connection was seamless - one minute I was talking to the Claimyr rep, the next I was speaking with an actual IRS employee who answered all my questions about the amendment process for my 2020 return. I've literally never been able to get through to the IRS in less than an hour before, and sometimes I've given up after 2+ hours on hold. This honestly saved me so much frustration and I got the exact information I needed. Just wanted to share since I was so openly doubtful before.

One thing to consider - if you're filing back taxes and expect refunds, double check if you had any stimulus payments during those years. For 2021 especially, if you didn't receive the third stimulus payment ($1,400 per person), you might be eligible to claim the Recovery Rebate Credit on your return. Also, if you had children and were eligible for the expanded Child Tax Credit in 2021, make sure that's accounted for. Those were partially sent as advance payments, but you might be eligible for the remainder. Those two things alone could significantly increase your refund for 2021!

•Oh wow, I completely forgot about the stimulus payment situation! I did receive the stimulus payments but definitely need to make sure I account for them properly. I don't have kids so the Child Tax Credit doesn't apply to me, but this is super helpful info for anyone else reading this thread. Do you know if the tax software will walk me through these special credits for past years? Or do I need to specifically look for them?

•Most tax software for 2021 should definitely ask you about stimulus payments received. They'll typically ask if you received the full amount, a partial amount, or nothing, and then calculate the Recovery Rebate Credit accordingly. If you received the full amount, you won't get more, but it's important to enter it correctly to avoid processing delays. Even though you don't have children, also check if you qualify for the Earned Income Tax Credit for those years. The eligibility was expanded for 2021, and more people without children qualified than in typical years. The income limits were higher too.

I just went through this whole process of filing 3 years of back taxes. My biggest piece of advice is to gather ALL your documents before starting. Make a checklist: - W-2s from all employers for each year - 1099s (interest, dividends, contractor work, etc) - Mortgage interest statements - Student loan interest - Health insurance forms - Any major life events (buying home, education, etc) Once you have everything organized by year, the software is actually pretty straightforward. I used TaxSlayer for all my back years and while it was a bit pricey (about $40 per year including state), their interface was really easy to use for someone who was overwhelmed like I was.

•Would you recommend doing all the years in the same software? I've heard some people say it's better to use the same company for all your back taxes so there's consistency, but others say to just use whatever is cheapest for each individual year.
