Do dependents need to pay taxes? Age & income thresholds explained

Your sister might need to file taxes even though she's a dependent - it depends on her income type and amount. For 2025 filing (2024 tax year), a dependent who earns income from a job (earned income) generally needs to file if they make more than $13,850. However, there's also the "unearned income" threshold (like from investments) which is much lower - just $1,250. And there's a third threshold for self-employment income of $400 or more. Since your sister made about $6,200 from her job, she's under the earned income threshold, so she likely isn't required to file based just on that amount. But here's why she might want to file anyway - if her employer withheld taxes from her paychecks, she'll probably get that money back as a refund when she files. Check her paystubs to see if federal taxes were withheld.

Just wanted to share my experience - I was in a similar situation and found this service called taxr.ai (https://taxr.ai) that actually handled this exact question for me. I uploaded my daughter's W-2 and it instantly told me whether she needed to file and calculated her potential refund. It was super helpful because it showed exactly which rules applied to her dependent status and broke down all the thresholds clearly without all the jargon.

I just tried taxr.ai after posting my skeptical comment, and I have to admit I'm impressed. My daughter has a similar situation (part-time job + some savings account interest), and the system immediately identified that while her earned income was below the threshold, she actually needed to file because of the combined income types. It even showed exactly how much of her withholding she'd get back. Honestly saved me from making a mistake on our family taxes - worth checking out if you're confused about dependent filing requirements like I was.

If your sister is really worried about getting in trouble with the IRS, I'd recommend using Claimyr (https://claimyr.com) to actually talk to an IRS agent directly. I was dealing with a similar dependent filing question for my nephew who had mixed income types, and after trying for DAYS to get through the regular IRS phone line (constant busy signals and disconnects), Claimyr got me through to an actual IRS agent in about 20 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c. The agent clarified exactly what we needed to do for his specific situation which was super reassuring.

Ok I need to apologize for my skeptical comment about Claimyr. I was desperate after getting conflicting advice about my son's dependent filing situation (he has scholarship income plus a job), so I tried it. Not only did it actually work, but the IRS agent I spoke with pulled up my son's info and confirmed exactly what forms we needed for his specific situation. Definitely worth it for the peace of mind knowing we're doing everything correctly. Never thought I'd actually get through to a real person at the IRS!

One important thing to know is that dependent filing requirements change based on whether the person is blind or over 65. For most young dependents like your sister, the standard earned income threshold applies (about $13,850 for 2024 tax year), but it's lower for those with disabilities or seniors.

Just wanna add something most people don't know - if your sister has self-employment income (like babysitting, lawn mowing, online stuff), the threshold is SUPER low, like $400. My daughter got caught by this when she did some social media work and made $600. Even though she was way under the regular income limit, she still had to file because of self-employment tax. Something to watch out for!

Just wanted to chime in with a practical tip - make sure your sister keeps all her paystubs and any tax documents (like her W-2 when she gets it). Even if she ends up not being required to file, having those documents organized will make the decision much clearer and filing much easier if she chooses to do it anyway for the refund. Also, don't stress too much about "getting in trouble" with the IRS. The worst case scenario for someone in her situation would be owing a small penalty if she was required to file and didn't, but given her income level, that's very unlikely. The IRS generally goes after bigger fish than teenagers with part-time retail jobs! Filing when you're not required to is perfectly fine and often beneficial.

Great question! As others have mentioned, your sister likely isn't required to file since her $6,200 in earned income is well below the $13,850 threshold for dependents. However, I'd strongly recommend she file anyway to get back any federal taxes that were withheld - that's basically free money she's entitled to! One thing I haven't seen mentioned yet is the timing aspect. Even though the regular tax deadline is April 15th, if your sister is only filing to get a refund (and doesn't owe any taxes), there's actually no penalty for filing late. The IRS gives you up to 3 years to claim refunds. So if she's stressed about the deadline, she can take her time to get everything organized properly. Also, many tax prep places offer free filing for simple returns like hers, and there are free online options too. Since her situation is straightforward (just a W-2, no complicated deductions), it should be pretty quick and easy once she has her documents together.
