What's actually considered federal taxes? Is it only federal income tax or more?
So I've been trying to fill out this tax refund calculator and I'm totally confused about what counts as "federal taxes." I thought it was just federal income tax, but now I'm second-guessing myself. The calculator is asking me to enter how much I paid in federal taxes for the year, but I'm not sure if that's JUST federal income tax from my paychecks or if it includes other stuff too like Social Security and Medicare taxes. I checked my W-2 and there are different boxes for federal income tax (Box 2), Social Security tax (Box 4), and Medicare tax (Box 6). When people talk about "federal taxes," do they mean just Box 2 or the combination of all these? Sorry if this is super basic, but I've been looking online for hours and getting mixed messages. Some sites seem to lump it all together when they say "federal taxes" and others are more specific about "federal income tax" only. Anyone who can clarify this for me would be a lifesaver before I mess up my calculations!

When a tax calculator asks for "federal taxes," it's typically asking specifically for federal income tax (Box 2 on your W-2), not the total of all federally mandated taxes. The three main types of federal taxes on your paycheck are: 1. Federal income tax - This is what most people mean when they say "federal taxes" in the context of tax returns and refunds 2. Social Security tax (FICA) - Currently 6.2% of your wages 3. Medicare tax - Currently 1.45% of your wages For tax filing purposes and when using refund calculators, "federal taxes" almost always refers to just your income tax. The Social Security and Medicare taxes are separate withholdings that generally aren't part of your annual tax return calculations unless you're self-employed or have special circumstances. When you're filling out that calculator, just use the amount from Box 2 of your W-2, which is your federal income tax withholding.

•Thanks for explaining! I'm still a bit confused though - if Social Security and Medicare are federal taxes too, why don't we get refunds on those if too much was taken out? And do state income taxes work the same way?

•Social Security and Medicare taxes are fixed percentages with very specific rules. For most W-2 employees, these are withheld at exact rates (6.2% for Social Security up to a wage limit, and 1.45% for Medicare on all wages), so there's typically no overpayment to refund. Unlike federal income tax which is based on your estimated annual liability and can be over-withheld. State income taxes work similarly to federal income taxes - they're estimated withholdings that you reconcile when filing your state tax return. If too much was withheld from your paychecks for state income tax, you can get a refund when you file your state return, just like with federal income tax.

I was in exactly the same boat last year! After hours of frustration trying to figure out my taxes, I stumbled across taxr.ai (https://taxr.ai) and it was a game-changer. Their system actually analyzes your tax documents and walks you through what each box means and what counts as "federal taxes" vs other withholdings. The way it worked for me was I uploaded my W-2 and other documents, and it automatically identified the federal income tax amount (Box 2) as what I should be using for federal taxes paid. It also explained the difference between income tax and the FICA taxes (Social Security and Medicare) which are separate things entirely. It saved me from making a costly mistake on my return because I was about to use the wrong numbers too!

•Did you have to pay for it? And does it actually file your taxes or just explain things? I'm looking at the website but can't tell exactly what it does.

•How is this different from just using TurboTax or H&R Block? They ask questions too and tell you which numbers to enter from your W-2. Is this just another tax prep software?

•It's not a tax filing service - it's more like a coach that reviews your documents and explains everything. I still used my regular tax software to file, but taxr.ai helped me understand what I was doing first. It identified several deductions I was missing too since I had side income. The biggest difference from TurboTax is that this actually explains WHY you're entering certain numbers and what they mean, not just telling you "enter box 2 here." It helped me understand my taxes for the first time instead of just blindly following prompts. Plus it found some credits I qualified for that the standard software questions never picked up on.

I just wanted to update after trying taxr.ai - it's actually pretty helpful! I uploaded my W-2 and some 1099s and it immediately clarified the federal tax question for me. It specifically pointed out that for tax return purposes, "federal taxes" refers specifically to the federal income tax withheld (Box 2 on W-2), NOT Social Security or Medicare. What I liked was that it explained WHY these are treated differently - basically that income tax is based on your total situation and deductions, while the FICA taxes (Social Security/Medicare) are fixed percentages that don't change based on your tax return. It showed me a few other things I've been doing wrong on my taxes for years too! Definitely saved me from making a mistake on my refund calculation. Thanks for the recommendation!

Off topic but if you need to actually talk to someone at the IRS about federal taxes vs other withholdings, I'd recommend using Claimyr (https://claimyr.com). I was confused about similar tax questions last year and spent DAYS trying to get through to the IRS phone line. After waiting on hold for hours and getting disconnected twice, I tried this service. You can actually see how it works in this video: https://youtu.be/_kiP6q8DX5c. The service calls the IRS for you and then calls you when an actual human agent is on the line. I got through in like 45 minutes when I had been trying for days on my own. The IRS agent was able to explain exactly what counts as federal taxes for my specific situation, which was way more helpful than guessing based on internet searches.

•Wait, how does this even work? I thought the IRS phone system was just completely broken. How can a service get through when regular people can't?

•Sounds like a scam to me. Why would I pay someone to call the IRS when I can just do it myself? And how would they have any better luck getting through than I would? The IRS lines are the same for everyone.

•They use some kind of automated system that keeps dialing and navigating the IRS phone tree until it gets through. It's the same phone line everyone uses, but their system just handles the waiting and redialing automatically instead of you having to do it manually and stay on hold forever. I don't know the technical details, but it worked when I couldn't get through on my own after multiple attempts. It's basically like having an assistant who just sits there and manages the call until a human picks up, then connects you. The IRS doesn't know or care that you're using a service - they just see a regular call coming in.

I have to admit I was completely wrong about Claimyr. After my skeptical comment, I decided to try it anyway because I was desperate to ask the IRS some questions about my federal taxes versus other withholdings. I had already spent 3 hours on hold one day and 2 hours another day before getting disconnected both times. The Claimyr service actually worked exactly as advertised - I got a call back when an IRS agent was on the line about 37 minutes after starting the process. The agent explained that "federal taxes" on tax forms always refers specifically to federal income tax (not Social Security or Medicare) unless explicitly stated otherwise. She was super helpful and I didn't have to waste an entire day on hold. I wish I'd known about this service years ago considering how many hours of my life I've wasted on hold with the IRS!

To add another perspective that might help - I'm a gig worker and have to pay all my taxes myself (no employer withholding). Here's how the federal taxes break down for me: Federal Income Tax - this is what people typically mean by "federal taxes" and what goes on your 1040 form Self-employment tax - this is actually both Social Security and Medicare taxes combined (15.3% total since I pay both halves) Additional Medicare Tax - kicks in for higher income folks When I make quarterly estimated tax payments, I'm paying toward both income tax and self-employment tax, but they're calculated separately on my tax return. For your refund calculator, it definitely just wants the federal income tax amount from Box 2 on your W-2!

•Do you know if the refund calculator would want you to include any additional federal income tax you paid through estimated payments during the year? I had some side income and made quarterly payments in addition to my W-2 withholding.

•Yes, if you're using a tax refund calculator, you should include ALL federal income tax paid - both what was withheld from your W-2 job (Box 2) AND any estimated tax payments you made for side income. The calculator is trying to figure out if you've overpaid your total federal income tax obligation for the year, so it needs to know your total payments. Just make sure you're only counting federal income tax payments, not state taxes or self-employment taxes if you paid those separately.

Federal taxes is a broad term that can include all of these: - Federal income tax (what you're asked about for tax returns) - Social Security tax - Medicare tax - Federal unemployment tax (usually employer-paid) - Federal excise taxes (on things like fuel, alcohol, etc) But for tax filing and refund calculators, they're just asking about federal INCOME tax. Thats the only one you might get a refund on.

•Don't forget about federal estate taxes and gift taxes too! Though most people don't have to worry about those unless you're giving away over $17k to one person or have a multi-million dollar estate.

This is such a common source of confusion! I work in tax preparation and see this question all the time. When any tax software or calculator asks for "federal taxes," they're specifically referring to federal income tax only (Box 2 on your W-2). Here's a simple way to remember it: Social Security and Medicare taxes are "pay-as-you-go" - you pay exactly what you owe throughout the year at fixed rates. There's no annual reconciliation, so no refunds. Federal income tax, on the other hand, is estimated throughout the year based on your W-4 settings, but your actual tax liability depends on your final income, deductions, credits, etc. That's why you can get refunds - because your employer might have withheld too much based on the estimates. So for your refund calculator, just use the amount from Box 2. Don't overthink it - if they meant something else, they would specifically say "total federal withholdings" or something similar.

•This is exactly the clarification I needed! As someone who's been doing my own taxes for years but never really understood the difference, the "pay-as-you-go" vs "estimated withholding" explanation finally makes it click. I always wondered why I never got refunds on Social Security or Medicare taxes even when it felt like a lot was being taken out. Now I understand it's because those are calculated at exact rates, not estimates that need to be reconciled later. Thanks for breaking it down so clearly!

Just to add one more perspective that might help - I made this exact same mistake a few years ago! I was using a tax refund estimator and included ALL the federal taxes from my paystub (income tax + Social Security + Medicare) instead of just the federal income tax. The calculator gave me this wildly optimistic refund estimate that was way off from what I actually got. Turns out I was basically double-counting things because the calculator was designed to only work with federal income tax withholdings (Box 2). The key thing to remember is that when you file your actual tax return (Form 1040), there's a specific line that asks for "Federal income tax withheld" - and that's exactly what these calculators are asking for too. They're trying to estimate what your real tax return will look like. So definitely stick with just Box 2 from your W-2, and you'll get a much more accurate estimate of your potential refund!

•That's such a helpful real-world example! I can totally see how including all the federal withholdings would throw off the calculator completely. It makes sense now why the estimators are so specific about asking for "federal income tax" rather than just "federal taxes" - they're trying to match exactly what goes on your actual 1040 form. I'm definitely going to bookmark this thread because the explanations here are way clearer than anything I found in my hours of searching online. Thanks for sharing your mistake so the rest of us don't have to make it too!

This thread has been incredibly helpful! I've been preparing taxes for family members for years but always second-guessed myself on this exact question. The distinction between "pay-as-you-go" taxes (Social Security/Medicare) versus "estimated withholding" taxes (federal income tax) that Faith explained really clarifies why only income tax gets refunded. What I find most valuable here is that multiple people confirmed the same thing from different angles - whether you're using a refund calculator, filing your actual return, or talking to an IRS agent, "federal taxes" in tax contexts means federal income tax only (Box 2 on W-2). For anyone else reading this thread later: if you're ever unsure about which numbers to use from your tax documents, the key is to look for the specific term "federal income tax" rather than the broader "federal taxes." That distinction will save you from the confusion that brought us all here in the first place!

•This whole discussion has been a real eye-opener for me! I'm pretty new to doing my own taxes and honestly had no idea there was even a difference between these types of federal taxes. I always just assumed "federal taxes" meant everything the government takes out of my paycheck. The way everyone explained it here - especially the "pay-as-you-go" versus "estimated withholding" concept - makes so much more sense than anything I've read elsewhere. I was about to make the same mistake with a refund calculator that others mentioned, so this thread literally saved me from getting a completely wrong estimate. It's also reassuring to see that even people who've been doing taxes for years sometimes second-guess themselves on this stuff. Makes me feel less dumb for being confused about it! Thanks to everyone who shared their experiences and explanations.

I've been lurking in tax forums for a while but finally had to jump in here because this exact confusion cost me money last year! I was using one of those "quick refund estimate" tools and kept getting wildly different numbers depending on which tax amounts I entered. Turns out I was making it way more complicated than it needed to be. Like everyone else has confirmed, when tax calculators ask for "federal taxes paid," they want ONLY your federal income tax withholding (Box 2 on your W-2). The thing that finally made it click for me was realizing that these calculators are essentially trying to recreate what happens when you file your actual tax return. And on your real 1040 form, there's literally a line that says "Federal income tax withheld" - not "total federal taxes" or "all federal withholdings." The calculator is just trying to match that specific line. Once I started using only Box 2, my refund estimates became way more accurate and matched pretty closely to what I actually received. Definitely wish I'd found a thread like this earlier - would've saved me a lot of headache and confusion!

•This is exactly why I love this community! Your experience with those "quick refund estimate" tools really highlights how confusing this can be when you're trying to figure it out on your own. I went through something similar where I kept getting estimates that were off by hundreds of dollars until I realized I was including the wrong tax amounts. The point you made about the calculator trying to recreate your actual 1040 form is brilliant - that's such a clear way to think about it! When you put it that way, it makes perfect sense why they only want the federal income tax withholding and not the Social Security/Medicare taxes, since those don't appear on the income tax reconciliation part of your return. Thanks for sharing your real-world experience with this. It's reassuring to know that even when we think we're doing something wrong, there are others who've been through the exact same confusion and came out the other side with the right answer!

As a newcomer to tax filing, this thread has been absolutely invaluable! I was literally sitting here with my W-2 trying to figure out the same exact thing for a refund calculator, and stumbled across this discussion. What really helped me was seeing how many different people confirmed the same answer from their own experiences - that "federal taxes" in tax contexts specifically means federal income tax only (Box 2 on W-2), not the total of all federal withholdings. The real-world examples of people who made the mistake of including Social Security and Medicare taxes really drove the point home. The explanation about "pay-as-you-go" versus "estimated withholding" taxes was particularly enlightening. I never understood why some taxes could be refunded and others couldn't, but now it makes perfect sense that Social Security and Medicare are calculated at exact rates while income tax withholding is just an estimate that needs to be reconciled. For anyone else who finds this thread while struggling with the same question - definitely bookmark it! This is way clearer than any of the official tax resources I tried to read through. Thanks to everyone who shared their knowledge and experiences here.

•Welcome to the community and I'm so glad this thread helped you out! It's exactly these kinds of practical, real-world discussions that make navigating taxes so much easier. I was in the same boat when I first started doing my own taxes - the official IRS publications are technically accurate but can be really hard to parse when you just need a straightforward answer. What I love about this thread is how everyone shared their actual experiences and mistakes, which is honestly way more helpful than just reading the dry definitions. Sometimes learning what NOT to do (like including Social Security and Medicare in federal tax calculations) is just as valuable as learning the right way. You're definitely on the right track now with using just Box 2 for any tax calculators or refund estimates. And don't hesitate to ask questions in the community - there are lots of experienced folks here who are happy to help newcomers avoid the common pitfalls we've all stumbled through!
