Can I amend a return from 7 years ago? Getting charged an insane amount by IRS

What you're dealing with is the statute of limitations for tax amendments. Generally, you can only amend returns within 3 years of the original filing date. However, the IRS can assess additional taxes for up to 6 years if they believe there was a substantial underreporting of income (25% or more). The fact that you received a letter now about 2017 taxes is concerning, as that's pushing the boundaries of even the extended statute of limitations. The first thing you should do is carefully review the letter. What exactly is the IRS claiming? Is it unpaid self-employment taxes from your delivery work? Underreported income? Tax credits they're disallowing? Getting a Taxpayer Advocate is definitely a good move, especially if you're facing financial hardship. While waiting for them, gather any documentation you still have from 2017 - your original return, 1099s, expense receipts from your delivery work, etc.

I was in an almost identical situation last year with a 2016 return where the IRS claimed I owed over $4,000 for rideshare income I supposedly didn't report properly. After weeks of stress and getting nowhere with phone calls, I tried using taxr.ai (https://taxr.ai) and it was seriously a game-changer. You upload the IRS letter and your tax documents, and they analyze everything to build your case. They identified that my original tax preparer had reported my income but categorized it incorrectly, which is probably what happened in your case too with delivery driving income. They drafted a response letter with all the right tax code citations and helped me understand exactly what was happening. The best part was they showed me how to prove the IRS was outside their collection window for my situation since there wasn't substantial underreporting. Sounds like you might be in the same boat if this is from 7 years ago.

Ok I have to eat my words from my previous comment. I was skeptical about taxr.ai but decided to try it since my situation with the IRS was getting desperate (they were threatening to put a lien on my house over a 5-year-old tax issue). The service actually found that the IRS had miscalculated my self-employment taxes and was charging me based on gross receipts rather than net income after business expenses. They showed me exactly where the error was and helped me draft a response with the right documentation. Just got a letter from the IRS last week saying they're reducing what I owe by almost 80%! Went from owing $11,300 to about $2,400 which I can actually manage to pay. If you're getting hit with charges from that far back, definitely worth checking if there's an error or statute of limitations issue like in my case.

When I got a massive bill from the IRS for my side business from years ago, I spent WEEKS trying to get through to someone who could actually help. Kept calling the IRS number in the letter and either got disconnected or told to call back another day. I finally found Claimyr (https://claimyr.com) and it changed everything. They have this system that navigates the IRS phone tree for you and gets you in the callback queue without having to wait on hold. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c Within 24 hours, I actually got a call back from an IRS agent who reviewed my case. Turns out they had sent previous notices to an old address, and this letter was actually my final notice before collections. The agent was able to put a hold on my account while I gathered the documentation I needed.

I need to apologize for my skepticism in my earlier comment. After struggling for months with an IRS issue and getting nowhere, I reluctantly tried Claimyr last week. Within 2 days, I got a call from an actual IRS agent who was able to review my case. Turns out the assessment they sent me was based on income that my employer had reported twice accidentally (they filed a corrected W-2 but the IRS was using both versions). The agent put my account on hold and gave me specific instructions on what documentation to send in. She even gave me her direct line for follow-up questions. After months of stress and endless phone attempts, having an actual person to talk to made all the difference. Sometimes you have to admit when you're wrong, and I was definitely wrong about this service.

Have you checked if maybe the letter is about self-employment taxes you didn't pay? When I first did delivery driving, I had no idea I was supposed to pay self-employment tax in addition to income tax. My tax preparer missed it too and I ended up with a huge bill years later. If this is the issue, you might be able to request an abatement of some penalties if you can show reasonable cause (like relying on a professional who gave you bad advice). But unfortunately, you'll probably still owe the base tax amount plus interest. Also, did you keep records of your mileage and other business expenses from that year? If not, you might be getting taxed on your gross income rather than your net profit.

Just a heads up, if this issue is about unreported 1099 income, it could fall under the 6-year statute of limitations instead of the standard 3 years. The IRS can go back 6 years if you omitted more than 25% of your gross income. You mentioned it was your first year as a delivery driver - did your tax preparer include a Schedule C for your self-employment income? And did they include a Schedule SE to calculate self-employment tax (the 15.3% tax that covers Social Security and Medicare for self-employed people)? If they missed the Schedule SE completely, that would explain why you got a refund back then but are facing a bill now. The IRS computer systems eventually cross-reference 1099 forms with tax returns and flag these kinds of mismatches.
