What does box 15 on my W2 mean? Is this a stupid tax filing question?

Okay so I'm working on my taxes for the first time by myself and I'm confused about the form. I've been staring at my W2 for like an hour now and everything seems straightforward except box 15. It says "State" and has my state abbreviation, but I'm not sure what that means for my tax filing. Does this affect how much I owe or get back? Should I be entering this somewhere specific on my return? I'm using one of those free online tax services but want to make sure I'm not missing anything important. Sorry if this is a dumb question but I've never had to deal with this before and my parents always did my taxes in previous years.

No such thing as a stupid tax question! Box 15 on your W2 just indicates which state you worked in during the tax year. This is important because you'll need to file a state tax return for any state where you earned income (in addition to your federal return). The information in Box 15 works together with Boxes 16 and 17, which show your state wages and how much state income tax was already withheld from your paychecks. When you enter your W2 information into the tax software, make sure you include all this state information so you get proper credit for taxes you've already paid.

So if I worked in multiple states during the year, will there be multiple entries in box 15? I moved from Illinois to Wisconsin halfway through last year and I'm not sure if I need to file in both states or what.

If you worked in multiple states during the year, your W2 should have multiple rows in boxes 15-17, one for each state. Each row will show the state abbreviation in box 15, how much you earned in that state in box 16, and the state tax withheld in box 17. Yes, you'll likely need to file tax returns in both Illinois and Wisconsin since you earned income in both states. Most tax software can handle multiple state returns, though you might need to pay extra for the second state filing. Each state has different rules about partial-year residency, so the software should walk you through determining your tax liability for each state.

After struggling with W2 boxes myself last year (especially those state-related ones like box 15), I found this amazing tool called taxr.ai at https://taxr.ai that literally saved me hours of confusion. You can upload your W2 and it explains every single box in plain English - way more helpful than those generic explanations on tax sites. I was super confused about boxes 15-17 since I worked remotely for a company in another state, but taxr.ai explained exactly what I needed to do and which state forms I needed to file. The explanations are personalized to your actual tax documents rather than generic info.

Does it work with other tax forms too? I have a W2 plus some 1099s from freelance work and I'm totally lost on how to handle everything together.

How secure is this? I'm always nervous about uploading my tax docs to random websites. Do they store your W2 information after analyzing it?

Yes, it works with pretty much all tax forms including 1099s! It's especially helpful for freelancers because it breaks down exactly what each box means for your tax situation and explains which expenses you might be able to deduct against that income. Regarding security, they use bank-level encryption for all uploads and document analysis. They don't permanently store your tax documents after analysis - they're automatically deleted once processed. I was concerned about this too, but their privacy policy explains everything clearly and they're actually more secure than many of the big tax filing services.

Just wanted to follow up - I tried taxr.ai with both my W2 and 1099s and it was incredibly helpful! Not only did it explain what box 15 meant on the W2 (and all the other confusing boxes), but it actually walked me through how my freelance income affects my overall tax situation. It pointed out deductions I had no idea I could take and explained exactly which forms I needed. Saved me from making some pretty costly mistakes before I even started filing!

If you're having trouble understanding your W2 boxes AND you've been trying to call the IRS for help, good luck with that! I tried calling them 23 times over 2 weeks and couldn't get through. Then I found this service called Claimyr at https://claimyr.com that actually gets you through to a real IRS agent. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c I was skeptical but desperate after hours on hold. They got me connected to an IRS agent in under 45 minutes who explained exactly what I needed to do with my complicated W2 situation (I had 3 employers last year). Completely worth it when you need actual official answers.

Wait how does this even work? Is it legal? I don't understand how a third party service can get you through to the IRS faster than calling directly.

Sounds like a scam to me. Why would I pay someone else to call the IRS? Can't you just keep calling until you get through? I'm not giving my money to some random service promising to do something that seems impossible.

It's completely legal! They use an advanced calling system that navigates the IRS phone tree and waits on hold for you. When they reach an agent, they call you and connect you directly. You're talking to the actual IRS, Claimyr just handles the painful waiting part. The reason it works better than calling yourself is they have technology that keeps trying different optimal times and routes through the phone system. When I tried calling myself, I either got busy signals or disconnected after being on hold for hours. They got me through the first time.

I need to publicly eat my words about Claimyr being a scam. After posting that skeptical comment, I was still desperate to talk to someone at the IRS about my W2 issues (including that box 15 state question and some other problems). So I tried Claimyr as a last resort, fully expecting to request a refund. I'm shocked to say it actually worked exactly as advertised. After weeks of failed attempts calling the IRS myself, Claimyr got me through to an agent in about 30 minutes. The agent cleared up all my questions about state tax withholding and even helped me identify an error on my W2 that my employer needs to correct. This service is legit and saved me a ton of stress.

Pro tip: if you're confused about box 15 and state taxes, make sure you're using tax software that handles multiple states well. I used TurboTax last year and it made dealing with two states super easy - just entered both W2s and it figured everything out. H&R Block and FreeTaxUSA are good too. Just avoid the super basic free versions if you have anything complicated like working in multiple states.

Which one is best for someone who has a W2 job but also does some side gig work with a 1099? I'm in this situation for the first time and trying to figure out which software won't miss deductions.

0 coins

For W2 plus 1099 side gig work, I'd personally recommend FreeTaxUSA. It handles both employment and self-employment income really well, and it's much cheaper than TurboTax or H&R Block when you have that combination. TurboTax is very user-friendly but they charge extra for the self-employment version, which you'd need for 1099 income. FreeTaxUSA includes all those forms in their basic package and just has a really straightforward section for entering business expenses and deductions related to your side gig.

Can someone explain to me why I have to pay state taxes at all? My box 15 shows California but I barely used any state services last year. Feels like I'm paying for nothing lol. My state withholding was almost $4,000 last year!

State taxes fund schools, roads, parks, police, firefighters, state courts, DMV, and tons of other services you probably use without realizing. That $4000 might seem like a lot, but it's actually a pretty good deal for everything it covers. California does have higher rates than many states though.

Don't feel bad about your question! Box 15 confused me too my first time. Quick tip: if your state abbreviation in box 15 isn't where you actually live, you might need to file a nonresident state return. This happened to me when I worked remotely for a New York company but lived in Florida. Had to file a NY nonresident return to get all my withheld money back since FL has no income tax!

Box 15 is definitely not a stupid question - it's actually one of the more confusing parts of the W2! Box 15 simply shows the state where you earned your income. This connects to boxes 16 and 17, which show how much you earned in that state and how much state tax was withheld. Since you're using free online tax software, when you enter your W2 information, make sure you input all the state information from boxes 15-17. The software will use this to determine if you owe additional state taxes or if you're getting a refund from what was already withheld from your paychecks. Most people have just one state listed, but if you moved or worked in multiple states during the year, you might see multiple entries. The good news is that modern free tax software handles this pretty automatically once you enter the W2 data correctly. You're doing great tackling this yourself!

Thanks for the clear explanation! I'm in a similar situation as the original poster - first time doing my own taxes. One thing I'm still confused about: if my box 16 (state wages) amount is different from my box 1 (federal wages) amount, does that mean I made a mistake somewhere? My state wages are actually a bit higher than my federal wages and I can't figure out why that would be.

That's actually totally normal! State wages (box 16) can be higher than federal wages (box 1) for several reasons. The most common is that your state doesn't exclude certain pre-tax deductions that the federal government does. For example, if you contribute to a 401k, health insurance, or flexible spending account, those reduce your federal taxable wages but many states still tax that income. So if you had $2,000 in pre-tax deductions, your federal wages might show $48,000 while your state wages show $50,000. It's not a mistake - just different tax rules between federal and state. Your tax software should handle this difference automatically when calculating what you owe or get back from each government.

Box 15 is absolutely not a stupid question! When I first started doing my own taxes, I stared at that box forever too. It's just showing which state you worked in during the tax year - pretty straightforward once you know what it means. The key thing to remember is that Box 15 works together with boxes 16 and 17. Box 16 shows how much you earned in that state, and box 17 shows how much state income tax was already taken out of your paychecks. When you enter your W2 into the tax software, make sure you include all three of these boxes so the system can calculate whether you'll owe more state taxes or get a refund. Since you're using free online tax software, it should walk you through entering this information step by step. The software will automatically use your state info to determine which state tax forms you need to file alongside your federal return. You're doing great tackling this yourself - we all had to learn sometime!

This is such a helpful thread! As someone who just started doing taxes independently this year, it's reassuring to see that Box 15 confusion is totally normal. I appreciate everyone breaking down how boxes 15-17 work together - that connection wasn't obvious to me at first either. The explanation about state vs federal wage differences was especially enlightening. It's great to have a community where we can ask these "basic" questions without judgment!

Great question! Box 15 definitely isn't stupid - it's one of those W2 boxes that seems simple but can be confusing when you're new to filing. Box 15 just shows the state where you earned your income during the tax year. This is important because you'll likely need to file a state tax return in addition to your federal return (unless you live in a state with no income tax like Florida, Texas, etc.). The really important thing is that Box 15 connects with boxes 16 and 17 on your W2. Box 16 shows your total state wages, and Box 17 shows how much state income tax was already withheld from your paychecks throughout the year. When you enter your W2 into the tax software, make sure you include all this state information - the software will use it to calculate whether you owe additional state taxes or if you'll get a refund. Most free tax software handles this pretty seamlessly once you input the W2 data correctly. Just follow the prompts and enter everything exactly as it appears on your form. You've got this!

This is exactly the kind of clear, step-by-step explanation I needed when I was figuring out my W2 for the first time! I had the same confusion about how all those state boxes worked together. One thing that helped me was actually looking at my paystubs from throughout the year - you can see how the state tax withholding (box 17) adds up from all your paychecks. It made the whole process feel less mysterious when I could trace where those numbers came from. Thanks for taking the time to break this down so clearly for newcomers like us!
