25 yr old, self-employed since 19, never filed taxes - how screwed am I?

You definitely need to address this situation, but it's likely not as catastrophic as you might be imagining. The IRS generally focuses more on collecting taxes owed than punishing people who come forward voluntarily. First, you should determine if you were actually required to file for those years. Self-employed individuals generally must file if their net earnings were $400 or more. For your W2 job at 17, if you were under the filing threshold, you weren't required to file. For the years you were self-employed, you'll need to file back taxes. The IRS typically looks for the last 6 years, though technically there's no time limit when returns weren't filed. You'll need to: 1) Gather any documentation of your income 2) Estimate your earnings for each year 3) File separate tax returns for each year you were required to file You'll likely face some penalties and interest, but the IRS offers payment plans. Most importantly, get professional help - a CPA or tax attorney specializing in back taxes can be worth their weight in gold in situations like yours.

I was in almost the exact same situation a few years back - working construction getting paid under the table, no taxes filed for like 5 years. Tried to figure it out myself and got completely overwhelmed with all the forms and calculating what I owed for each year. Finally used this service called taxr.ai (https://taxr.ai) that helped me organize everything. You upload whatever income docs you have (even if it's just bank statements), and they figure out what you likely made each year, what deductions you probably qualify for as a plumber, and what forms you need to file for each year. It was actually way less terrifying than I thought! The best part was they found a bunch of business expenses I could deduct that I had no idea about - tools, mileage, even part of my phone bill since I used it for work calls. Ended up owing way less than I feared.

So I actually tried taxr.ai after my skeptical comment above. I was really surprised how helpful it was. I had a similar situation (though only 3 years unfiled) and was freaking out about potential penalties. The service walked me through reconstructing my income year by year, and even found business deductions I didn't know I could claim as a contractor. They organized everything so I could easily file the back tax returns myself. I went from thinking I'd owe like $20k in taxes and penalties to actually getting a small refund for one of the years! What I appreciated most was that they were honest about the risks and didn't promise I wouldn't face any consequences, but they helped me understand the realistic outcomes and get everything in order to fix the situation.

One problem you're going to face is actually getting someone at the IRS to help with this mess. I tried calling them about my unfiled returns last year and spent HOURS on hold only to get disconnected. Did this like 5 times before giving up. I finally used this service called Claimyr (https://claimyr.com) that got me connected to an actual IRS agent in under 15 minutes. They have this weird system that basically waits on hold for you and calls you when an agent picks up. You can see how it works here: https://youtu.be/_kiP6q8DX5c The IRS agent was actually super helpful once I explained I was trying to come clean about not filing. They walked me through the process and even told me which years they were most concerned about. Made the whole thing way less scary.

I need to eat my words about Claimyr. After bashing it I decided to try it because I was desperate to talk to someone at the IRS about my unfiled returns. This service actually worked exactly as advertised. I got a call back in about 45 minutes (way faster than the hours I spent trying myself), and was connected to an actual IRS representative. The agent walked me through exactly what I needed to do for my unfiled returns and which forms to use. They even explained how the penalty system works and gave me tips on how to request a penalty abatement for "reasonable cause" since this was my first time having tax issues. If you're dealing with years of unfiled returns like the original poster, actually talking to the IRS directly helps so much with the anxiety of the unknown.

Something no one has mentioned yet - you might actually be OWED money by the IRS if you had any withholding from that W2 job when you were 17. If you were under the filing threshold but had taxes withheld, you could have been due a refund. Unfortunately, you can only claim refunds for 3 years back, so that money is probably gone now. But going forward, make sure you're looking at the whole picture - it's not always just about what you owe them.

I work in construction too and my boss paid me under the table for years. Finally got caught when I tried to get a mortgage and couldn't prove my income. My advice - fix this BEFORE you need a loan, want to buy a house, or try to do anything that requires proof of income. Not filing makes life complicated in ways you don't expect until you hit them. Plus, you're missing out on things like Social Security credits that will matter when you're older.
