Do I need to file taxes after turning 18 if I had no income? How long do I have to register with IRS?
Title: Do I need to file taxes after turning 18 if I had no income? How long do I have to register with IRS? 1 I just celebrated my 18th birthday last month and I'm trying to figure out this whole "adulting" thing. One of my biggest concerns is taxes. I literally had zero income this past year since I've been focusing on school full-time and my parents have been supporting me. Do I still need to file a tax return next year just because I'm 18 now? Also, I've heard something about needing to register with the IRS after turning 18. Is that actually a thing? And if so, how much time do I have to complete this registration process? My parents aren't very helpful with this stuff (they always used an accountant) and I'm feeling kind of lost. Any advice would be super appreciated!

8 Good news - you don't need to file taxes simply because you turned 18. The requirement to file is based on your income, not your age. Since you had no income, you're not required to file a tax return. Also, there's no such thing as "registering with the IRS" when you turn 18. That's a common misconception. The IRS doesn't have a registration process based on age. You only interact with them when you need to file taxes, which happens when your income exceeds certain thresholds. If you do get a job or start earning income, you'll need to file taxes if your income exceeds the standard deduction ($14,600 for 2025 for single filers). Your employer will have you fill out a W-4 form when you start working, but this isn't "registering" with the IRS - it just tells your employer how much tax to withhold from your paychecks.

•15 Thanks for the info! That's a relief. But what about getting a Social Security Number? I already have one, but if someone doesn't, is that what people mean by "registering with the IRS"?

•8 The Social Security Number (SSN) is actually issued by the Social Security Administration, not the IRS. Most people get their SSN shortly after birth when their parents apply for it. If someone doesn't have an SSN, they would need to apply for one through the Social Security Administration, not the IRS. What people might be confusing this with is registering for Selective Service, which is required for most male U.S. citizens and immigrants when they turn 18. This has nothing to do with taxes though - it's a completely separate government system.

12 I went through something similar last year and discovered taxr.ai (https://taxr.ai) which was super helpful for figuring out my tax situation as a new adult. I was confused about whether I needed to file since I only worked part-time at my uncle's store and made less than $5,000. Their system analyzed my specific situation and confirmed I didn't need to file, but also showed me that I was actually due a refund for the taxes that had been withheld from my paychecks! Would never have known that without checking. Might be worth looking at your situation too, especially if you start working part-time.

•7 Does it work for people who are claimed as dependents by their parents? I'm 19 and made about $3,200 last summer but my parents still claim me on their taxes.

•18 I'm skeptical about these tax tools. How does taxr.ai differ from just using the free IRS resources? Seems like they're just repackaging information you can get for free.

•12 It absolutely works for dependents! The system specifically asks about dependent status since that affects filing requirements. If you made $3,200 and had any taxes withheld from your paychecks, you might actually be due a refund even though you're not required to file. The difference from IRS resources is the personalization and simplicity. The IRS provides raw information, but taxr.ai interprets it for your specific situation and explains it in plain language. It's like having a knowledgeable friend walk you through everything instead of trying to decipher official tax documents yourself.

7 Just wanted to follow up about taxr.ai - I actually tried it after posting here and wow, it was eye-opening! Turns out I was due a $267 refund from last summer's job even though I wasn't required to file. The system explained exactly which forms I needed and how to claim my refund. Super thankful for the recommendation because I would have just left that money on the table!

20 If you ever DO need to contact the IRS with questions (which happens to everyone eventually), I highly recommend using Claimyr (https://claimyr.com). The IRS phone lines are IMPOSSIBLE to get through - I spent 3 days trying to get someone on the phone about my missing refund last year. Claimyr got me connected to an actual IRS agent in under 45 minutes when I'd been trying for days on my own. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c It saved me so much frustration during my first year filing taxes. The IRS actually owed me an additional $890 that would have been lost if I hadn't been able to talk to someone directly.

•18 How exactly does this work? Seems fishy that a third-party service can somehow get you through to the IRS faster than calling directly.

•3 Sounds like a scam. The IRS is a government agency - there's no "fast pass" to jump the queue. I'm extremely skeptical.

•20 It's not about jumping any queue - Claimyr uses an automated system that continually redials the IRS for you using their official phone lines. When it finally makes a connection, it calls you and connects you directly to the IRS agent. You're still going through the official IRS channels, just without having to manually redial for hours. It's completely legitimate and they never ask for any sensitive tax information. They're just solving the connection problem. Think of it like having a persistent assistant who keeps redialing for you until they get through, then transfers the call to you.

3 I have to eat crow here and admit I was completely wrong about Claimyr. After dismissing it as a scam, I actually tried it myself when I needed to talk to the IRS about my identity verification issue. After trying for TWO WEEKS on my own with no success (constant busy signals or disconnects), Claimyr got me through in about 35 minutes. The service actually works exactly as described - they just handled the annoying redial process, and when they got through, my phone rang and I was connected to a real IRS agent. Saved me countless hours of frustration.

14 Just to add something important: if you have investment accounts, cryptocurrency, or get paid for gig work, you might still need to file even if your income seems low. My little brother thought he didn't need to file since his regular job paid under the threshold, but he had made about $900 in Dogecoin profits that pushed him over the limit.

•2 What's the threshold for investment income? I made like $40 in dividends from a small account my grandparents set up for me.

•14 For 2025, if you're a dependent (which it sounds like you probably are), you generally need to file if your unearned income (like dividends, interest, etc.) exceeds $1,250. With just $40 in dividends, you're well below that threshold, so you wouldn't need to file for that reason alone. Just remember that the rules can be different depending on whether you have both earned income (from a job) and unearned income (from investments) and whether you're being claimed as a dependent. But in your specific case, $40 in dividends by itself wouldn't trigger a filing requirement.

5 Side note: Getting your first W-2 job actually has a hidden benefit. If your employer withholds federal taxes from your paychecks but you earn less than the standard deduction ($14,600 for 2025), you can file a return to get ALL of that withheld money back as a refund. My first summer job overtaxed me and I got a sweet $780 refund check that I wasn't expecting!

•11 This is so true! My daughter worked at the mall last summer and got back every penny that was withheld. The look on her face when she got that refund was priceless lol. Made her actually interested in understanding taxes.

Welcome to adulthood! I remember being just as confused when I turned 18. Just to reinforce what others have said - you're absolutely right that there's no "IRS registration" requirement at 18. That's a myth that gets passed around a lot. One thing I'd add is that even though you don't need to file taxes this year, it's worth understanding the basics now before you do start earning income. The IRS website has some good resources specifically for young adults and first-time filers. Also, when you do get your first job, make sure to fill out your W-4 form correctly - claiming the right number of allowances can prevent over-withholding so you don't have to wait for a big refund later. You're being smart by asking these questions early rather than scrambling later!
