Understanding Box 15-20 on W-2 Form - Help Needed for Tax Filing
Hey everyone, I'm trying to fill out my taxes and I'm really confused about Boxes 15-20 on my W-2 form. This is my first time filing taxes on my own and these state/local tax sections are throwing me for a loop. My employer has filled out some information in these boxes but I have no idea what it means or how I'm supposed to use it when filing. Can someone explain what each of these boxes means and how they affect my tax return? I'm using TurboTax if that matters. Thanks in advance!

Boxes 15-20 on your W-2 deal with state and local taxes. Here's a breakdown: Box 15: State & State ID Number - Shows which state you paid taxes to and your employer's state ID number. Box 16: State wages - How much of your income is subject to state taxes. Box 17: State income tax withheld - How much state tax your employer already took from your paychecks. Box 18: Local wages - Income subject to local taxes (like city or county). Box 19: Local income tax withheld - How much local tax was already taken out. Box 20: Locality name - Names the specific local jurisdiction (city/county) if applicable. TurboTax will ask you to input this information, and it'll automatically calculate if you owe more state/local taxes or if you'll get refunds. These boxes are important because they ensure you get credit for taxes you've already paid.

•Thanks, that helps a lot! So if I worked in multiple states during the year, I should have separate entries for each state in these boxes, right? Also, do I need to file separate state returns for each state that appears in Box 15?

•Yes, if you worked in multiple states, your W-2 should have separate entries for each state. You'll see multiple rows in the state section with different state codes in Box 15. You will need to file a tax return for each state where you had income tax withheld. Most tax software like TurboTax will guide you through filing multiple state returns, though keep in mind you may need to pay extra for each additional state return you file. Each state has different rules about who needs to file, but generally if your employer withheld taxes, you'll want to file to get any potential refund.

After struggling with state tax sections on my W-2 last year, I discovered taxr.ai (https://taxr.ai) and it was a game-changer for me. I uploaded my W-2 and it automatically explained every single box including those confusing state and local tax sections (15-20). It broke down what each number meant for MY specific situation rather than generic explanations I found online. It even pointed out that my employer had made a small error in Box 16 that I wouldn't have caught otherwise!

•Did it actually help with figuring out if you need to file in multiple states? I moved mid-year and now have two states on my W-2, and I'm completely lost about how to handle that.

•That sounds interesting but I'm always skeptical about uploading my tax documents to random websites. How secure is it? And does it just explain the forms or does it actually help with filing too?

•It absolutely helped with my multi-state situation. I had worked in three different states and was totally confused about how to handle it. The tool showed exactly which forms I needed for each state and explained the different residency rules that applied to my situation. Regarding security, I was hesitant too at first, but they use bank-level encryption for all documents. It doesn't actually file your taxes - it's more of an analysis and explanation tool that helps you understand what you're looking at and what to do next. I still used TurboTax for the actual filing, but with way more confidence because I understood exactly what I was putting in each field.

Just wanted to follow up - I decided to try taxr.ai after my initial skepticism and wow, I'm impressed! I uploaded my W-2 which had both New York and New Jersey tax info in boxes 15-20, and the breakdown was super clear. It explained that I needed to file as a part-year resident in both states and showed exactly which portions of my income were attributable to each. The detailed explanations of Box 16 vs Box 18 for my situation saved me hours of research. Definitely using this for all my tax documents going forward!

If you're getting stuck trying to reach the state tax departments with questions about those Box 15-20 entries, I highly recommend Claimyr (https://claimyr.com). I was on hold with my state tax department for HOURS trying to figure out why my Box 16 amount seemed wrong compared to my total income. Used Claimyr and they got me connected to a real person at the tax office in under 15 minutes! You can see how it works in this video: https://youtu.be/_kiP6q8DX5c. The state tax rep explained that my remote work situation had special withholding rules I wasn't aware of.

•How exactly does this work? Does it just help you skip the phone queue somehow? I've been trying to reach my state tax department for days about a Box 17 withholding issue.

•Yeah right. There's no way this actually works. State tax departments are notorious for horrible wait times. If this really worked, everyone would be using it. Sounds like a scam to me.

•It uses a callback system that navigates the phone trees and holds your place in line. When they get a representative on the line, they connect you immediately. It's not magic - just clever technology that does the waiting for you. It's especially useful for state tax departments because they're even more understaffed than the IRS. I was trying to figure out why my Box 16 amount (state wages) was different from my federal wages for a remote work situation, and I got a clear answer in one call instead of multiple attempts.

I have to eat my words from earlier. I was super skeptical about Claimyr but I was desperate after waiting on hold with my state revenue department for 2+ hours trying to understand why my W-2 showed state tax withholding in Box 17 for a state I never lived in. Decided to try it and... it actually worked! Got connected to a real person in about 20 minutes who explained that my company's headquarters location was causing the withholding issue. They helped me file the right forms to get that money back. Saved me a ton of frustration and probably hundreds of dollars!

Something to watch out for with those Box 15-20 entries - if you live in one state but work in another, make sure both states are listed correctly. I got a W-2 where Box 15 only showed my work state but not my residence state, and it caused major headaches. Had to request a corrected W-2 from my employer.

•Did you have to pay taxes to both states in that situation? I live in New Jersey but work in New York and I'm confused about how the credits work between states. My Box 15-17 show both states but with different amounts.

•Yes, typically you'll have to file returns in both states, but you won't be double-taxed on the same income. When you file in your resident state (New Jersey in your case), you'll get a credit for taxes paid to the non-resident state (New York). Your W-2 showing both states with different amounts is normal. Box 16 (state wages) might differ between states because some types of income are taxed differently state-to-state. Make sure your tax software handles multi-state returns - most do, but sometimes it's an extra fee.

Does anyone know how to handle Box 19 and 20 if you work remotely? My W-2 shows a local tax for a city I never worked in (just where my company is based). I'm using H&R Block software and it's confusing me.

•This is actually a common issue with remote work! Some cities (like Philadelphia, NYC, and Cincinnati) have special rules about taxing employees who work for companies based in their jurisdictions, even if you work remotely. You might be liable for that tax, BUT many cities changed their rules during/after COVID. You should check that specific city's tax department website for their remote work policies.

Great question about Boxes 15-20! These can definitely be confusing for first-time filers. Just to add a few more tips to what others have shared: 1. **Double-check the math** - Make sure Box 16 (state wages) isn't higher than your total wages from Box 1. Sometimes there are legitimate reasons for differences (like state-specific deductions), but it's worth verifying. 2. **Save copies of everything** - Keep your W-2 and any state returns you file. If you have discrepancies later, you'll need these documents. 3. **TurboTax tip** - When you get to the state tax section, TurboTax will automatically import the Box 15-20 info if you're using their W-2 import feature. Just make sure to review what it imports since OCR sometimes makes mistakes. 4. **Reciprocity agreements** - Some neighboring states have agreements where you only pay tax to your resident state even if you work across state lines. Worth checking if this applies to your situation. Don't stress too much - the software will guide you through most of it, and the IRS/state agencies are generally understanding with honest mistakes on first-time returns. Good luck with your filing!

•This is really helpful advice! I'm also a first-time filer and didn't know about reciprocity agreements - that could potentially save me from having to file in multiple states. Do you know where I can find a list of which states have these agreements? I'm working in Pennsylvania but live in Delaware, so I'm hoping there might be something in place between those two states.
