Where exactly does Schedule C profit/loss go on the new 1040 form?
So I'm filling out my taxes and I'm totally confused. I haven't had to use Schedule C in several years, and the 1040 form has completely changed since I last used it. The instructions say to put the profit or loss on line 3, but when I look at the form, there's only lines 3a and 3b which seem to be for dividends, not business income. I've been staring at this form for an hour trying to figure out where my Schedule C results are supposed to go. Did they move it to a different line? Am I missing something obvious here? The side gig I started last year wasn't huge but I definitely need to report it correctly. I appreciate any help from someone who's done this recently!

The Schedule C profit or loss goes on Schedule 1, not directly on Form 1040. This trips up a lot of people since the 1040 was redesigned a few years back. First complete your Schedule C to calculate your business profit or loss. Then you'll need to transfer that amount to Schedule 1 (Additional Income and Adjustments to Income), Line 3. After completing Schedule 1, the total from Line 26 of Schedule 1 gets transferred to Line 8 of your Form 1040. The IRS restructured the 1040 to be much shorter with more supplemental schedules, which is why you don't see a specific line for business income on the main 1040 form anymore.

•Thank you so much! I was looking at the main 1040 form only and completely missed the Schedule 1. No wonder I couldn't find where to put it. Do I need to attach both Schedule C and Schedule 1 when I file my taxes, or just the Schedule C?

•You need to attach both Schedule C and Schedule 1 when you file. Schedule C shows how you calculated your business profit or loss, and Schedule 1 is how that amount (along with other additional income) gets reported on your 1040. If you're using tax software, it should automatically generate and include both forms when you enter your business income. The software will transfer all the amounts to the correct places for you.

After struggling with a similar issue last year, I found this amazing tool called taxr.ai (https://taxr.ai) that saved me hours of confusion. I took a picture of my completed Schedule C and it showed me exactly where everything needed to go on my 1040 and which schedules I needed. It even explained why I needed Schedule 1 for my business income instead of entering it directly on the 1040. The tool highlighted specifically which line on Schedule 1 my Schedule C profit needed to go on and then showed me how that flowed to the 1040. I've never had tax forms explained so clearly before.

•Does it work for other schedules too? I've got some rental income and I'm never sure if I'm putting everything in the right place.

•I'm a bit skeptical about using random tax tools. How do you know it's giving accurate information? Does it explain the tax laws or just tell you where to put numbers?

•It works great for rental income - it'll show you exactly where Schedule E info goes and how it flows through to your 1040. It breaks down each section with simple explanations. As for accuracy, that's what impressed me the most. It actually shows you the relevant IRS rules and publications while explaining each step. It's not just telling you where to put numbers - it's teaching you why they go there based on official tax code. That's why I trust it more than random internet advice.

Ok I tried that taxr.ai site after commenting and I have to admit I was wrong to be skeptical. I uploaded my self-employment docs and it immediately showed me that I'd been making a mistake on my SE tax calculation for years! It even showed the specific IRS publication explaining why my approach was incorrect. The step-by-step breakdown for Schedule C to Schedule 1 to Form 1040 was crystal clear, and saved me from underpaying my taxes again. Actually learning WHY things go where they do instead of just blindly filling out forms makes a huge difference. Now I finally understand how all these schedules fit together!

If you're still having trouble with your Schedule C even after getting advice here, try Claimyr (https://claimyr.com). I was completely lost with my side gig taxes last year and kept getting contradictory info online. After wasting days on hold trying to reach the IRS, I used Claimyr and got connected to an actual IRS agent in under 20 minutes. The agent walked me through exactly where my Schedule C income needed to go and explained all the deductions I was eligible for. Definitely worth checking out their demo at https://youtu.be/_kiP6q8DX5c if you're struggling with any tax questions. Getting direct answers from the IRS saved me so much stress.

•How does this actually work? I've tried calling the IRS before and gave up after being on hold for 2 hours. Does this service somehow jump the queue?

•Sorry but this sounds too good to be true. The IRS phone lines are notoriously backed up for months. No way some random service can get you through in 20 minutes when everyone else waits for hours or days.

•It uses a system that continuously redials the IRS for you and navigates through their phone tree automatically. Once it gets through, it calls you and connects you directly to the agent. It's basically doing all the waiting and navigating for you in the background. I was skeptical too but it actually works. It's not jumping any queue - it's just automating the frustrating part of the process. It took 17 minutes in my case, but from what I understand the time varies depending on call volume. Either way, it beats spending your whole day pressing redial and listening to hold music.

I have to eat crow here. After adamantly claiming Claimyr wouldn't work, I tried it this morning as a last resort. I've been trying to reach the IRS about my Schedule C issue for two weeks with no luck. I used Claimyr and got connected to an IRS agent in about 25 minutes. The agent confirmed exactly what others here said - Schedule C profit goes on Schedule 1, Line 3, and then Schedule 1, Line 26 total goes on Form 1040, Line 8. She also pointed out that I'd missed some deductions I was eligible for as a self-employed person. Seriously shocked this worked. Saved me at least another week of frustration and potentially hundreds in overpaid taxes.

One thing nobody mentioned is that if you have a loss on Schedule C (meaning your business expenses exceed your income), you still put it on Schedule 1, Line 3. The loss will show as a negative number and will reduce your overall taxable income. Just make sure you're eligible to deduct the loss - there are rules about whether your business activity is profit-motivated or just a hobby. If the IRS determines it's a hobby, you can't deduct losses.

•How many years can you show a loss before the IRS considers your business a hobby? I've heard it's 3 years but not sure if that's accurate.

Alexis Robinson
•The "3 years" guideline is somewhat of a myth. The IRS doesn't have a specific number of years that automatically makes your activity a hobby. They use what's called the "9 factor test" to determine if your activity is a business or hobby. Some of these factors include whether you carry on the activity in a businesslike manner, your expertise, time and effort invested, history of income/losses, and reasonable expectation of profit. Generally speaking, showing a profit in 3 out of 5 consecutive years is considered a safe harbor for most businesses (5 out of 7 years for horse breeding/training).

I file Schedule C every year, and the location for reporting it has definitely changed since the 1040 redesign. There's a flow you need to follow: 1. Complete Schedule C to get your net profit/loss 2. Enter that amount on Schedule 1, Line 3 3. Complete the rest of Schedule 1 4. The total from Schedule 1, Line 26 goes on Form 1040, Line 8 If you're using tax software like TurboTax or H&R Block, it handles all this automatically. You just enter your business income and expenses, and it puts everything on the right forms and lines.

•Does this same process apply for multiple Schedule Cs? I have two side businesses this year.

Carmella Fromis
•Yes, the same process applies for multiple Schedule Cs. You'll need to complete a separate Schedule C for each business, then add up the net profit/loss from all your Schedule Cs and enter the total on Schedule 1, Line 3. So if Business A has a $5,000 profit and Business B has a $1,000 loss, you'd enter $4,000 on Schedule 1, Line 3. The IRS wants to see the individual Schedule C forms for each business, but the combined result goes on Schedule 1. Make sure you keep good records separating the income and expenses for each business - don't mix them together on one Schedule C.

Just wanted to add one more helpful tip for anyone still confused about the Schedule C process - if you're filing electronically, make sure your tax software is updated to the latest version. I made the mistake last year of using an outdated version that had the old 1040 form structure, and it kept trying to put my Schedule C income on the wrong lines. The current process is definitely: Schedule C → Schedule 1 (Line 3) → Form 1040 (Line 8). But if your software isn't current, it might still be following the old form structure and cause errors when you try to e-file. Also, don't forget that if you have net earnings from self-employment of $400 or more, you'll also need to file Schedule SE for self-employment tax, which is separate from your regular income tax calculation.

•Great point about the software updates! I ran into a similar issue where my tax prep software was showing outdated forms. One thing I'd add is that the Schedule SE requirement catches a lot of people off guard. Even if your Schedule C profit is small, you still owe self-employment tax on it, which covers Social Security and Medicare contributions. The current SE tax rate is 15.3% (12.4% for Social Security + 2.9% for Medicare), but you get to deduct half of it as an adjustment to income. For anyone just starting with self-employment, it's worth setting aside about 25-30% of your profit for taxes throughout the year since you'll owe both income tax and self-employment tax on your Schedule C earnings.

This thread has been incredibly helpful! I just wanted to share my experience as someone who was in Logan's exact situation last month. After reading through all the advice here, I can confirm the process is: Schedule C (calculate profit/loss) → Schedule 1 Line 3 → Form 1040 Line 8 What really helped me was printing out all three forms and physically tracing the numbers with a highlighter to see how they flow from one form to the next. Sometimes seeing it on paper makes more sense than staring at a computer screen. One additional tip: if you're doing this by hand, double-check your math on Schedule C before transferring anything. I caught a $500 error in my expense calculations that would have cost me in overpaid taxes. The IRS forms are actually pretty logical once you understand the flow - it's just that the redesigned 1040 moved a lot of things to supplemental schedules that used to be on the main form. Thanks everyone for sharing your knowledge and experiences!

•This is such a great summary, Dylan! The highlighter trick is brilliant - I'm definitely going to try that approach next year. It's so easy to get lost in all the form numbers and line references when you're doing taxes. I also appreciate you mentioning the double-checking of Schedule C calculations. I made a similar mistake last year where I miscategorized some business expenses and it threw off my entire return. Now I always go through my Schedule C line by line before moving anything to Schedule 1. For anyone still feeling overwhelmed by this process, don't be afraid to start with the paper forms first even if you plan to file electronically. Understanding the flow between Schedule C → Schedule 1 → Form 1040 on paper really does make the whole thing click into place. Then you can use tax software with confidence knowing exactly what it's doing behind the scenes.

As someone who just went through this exact same confusion a few weeks ago, I can confirm what everyone here is saying. The key thing that finally made it click for me was understanding that the new 1040 is basically just a summary form now - most of the actual detail work happens on the schedules. Here's what worked for me: I laid out Schedule C, Schedule 1, and Form 1040 side by side and traced the path with my finger. Your Schedule C profit/loss goes to Schedule 1 Line 3, then the total from Schedule 1 Line 26 goes to Form 1040 Line 8. It's actually pretty straightforward once you see the connection. One thing I wish someone had told me earlier - if you're using tax software, don't panic if you don't see your Schedule C amount directly on the main 1040 form. The software is doing all the behind-the-scenes work with Schedule 1 for you. But if you're filing by hand like I did, make sure you don't forget to include Schedule 1 with your return - that's where your business income actually gets reported to the IRS. Hope this helps clarify things for you, Logan!

•Thanks Debra! Your explanation about the 1040 being more of a summary form now really helps put everything in perspective. I've been doing my own taxes for years but took a break from self-employment, so coming back to these changes was really confusing. I like your suggestion about laying the forms out side by side - that visual approach seems like it would help me understand the flow better than just reading instructions. I'm definitely going to try that method when I sit down to finish my return this weekend. One quick follow-up question: when you filed by hand, did you need to staple the schedules in any particular order, or does it not matter as long as they're all included?

I went through this same confusion when I started freelancing last year! The redesigned 1040 definitely throws people off at first. What helped me understand the flow was thinking of it like a funnel system: Schedule C calculates your business profit/loss, Schedule 1 collects that along with other additional income types, and then Form 1040 gets the final summary number from Schedule 1. For filing order when doing it by hand, I always put them in the sequence they reference each other: Form 1040 first, then Schedule 1, then Schedule C. That way if an IRS processor needs to trace the numbers, they follow the same logical path. Though honestly, as long as all the forms are included with matching SSNs, they can figure it out. One more tip that saved me time: before you transfer any numbers between forms, circle the amounts on each form so you can easily double-check your work. It's easy to copy the wrong number when you're moving between multiple forms!

•Isaiah, that's a really helpful way to think about it - the funnel system analogy makes perfect sense! I never thought about arranging the forms in reference order when filing by hand, but that logical flow definitely makes sense for anyone who might need to review the return later. The tip about circling amounts before transferring them is gold. I can't tell you how many times I've copied numbers from the wrong line or transposed digits when moving between forms. Having those amounts clearly marked would definitely help catch those kinds of errors before they become bigger problems. Thanks for sharing your experience - it's reassuring to know that others have gone through this same learning curve with the redesigned forms. The tax system can feel overwhelming when you're trying to figure it out on your own, but threads like this really show how helpful the community can be!

I just wanted to jump in and say how helpful this entire thread has been! I'm new to filing Schedule C and was completely lost until I found this discussion. The step-by-step breakdown that everyone's provided (Schedule C → Schedule 1 Line 3 → Form 1040 Line 8) is exactly what I needed. I've been searching through IRS publications trying to figure this out, but seeing it explained by people who've actually been through the process makes it so much clearer. I especially appreciate the practical tips like using highlighters to trace the numbers between forms and laying everything out side by side. Sometimes the simplest approaches work best when you're dealing with confusing tax forms. As someone who just started a small consulting business this year, I had no idea about the Schedule SE requirement either. That 15.3% self-employment tax was definitely not on my radar, so thank you to everyone who mentioned that. I'll make sure to factor that into my quarterly payments going forward. This community is such a valuable resource for navigating these tax changes. Thanks to everyone who took the time to share their experiences!

•Welcome to the world of self-employment taxes, NebulaNinja! I'm glad this thread helped clarify the Schedule C process for you. One thing I'd add to help with your quarterly payments - since you mentioned you're new to this - is to look into Form 1040-ES for estimated tax payments. The IRS expects you to pay taxes throughout the year on self-employment income, not just when you file your annual return. Generally, if you expect to owe $1,000 or more in taxes, you should be making quarterly payments. The safe harbor rule is helpful here: if you pay 100% of last year's tax liability through withholding and estimated payments (110% if your prior year AGI was over $150,000), you won't face underpayment penalties even if you end up owing more when you file. Since you're doing consulting work, also keep detailed records of all business expenses throughout the year - mileage, office supplies, professional development, etc. These deductions on Schedule C can really add up and reduce both your income tax and self-employment tax burden. Good luck with your new business!

I just want to echo what everyone has said here - the Schedule C to Schedule 1 to Form 1040 flow is exactly right, and this thread has been incredibly educational to read through! I went through this same confusion two years ago when I started my photography side business. What really helped me was creating a simple flowchart on paper: "Schedule C (business profit/loss) → Schedule 1 Line 3 → Schedule 1 Line 26 total → Form 1040 Line 8." I still keep that note taped to my desk during tax season. For anyone using tax software, don't worry if you can't see where your Schedule C income "goes" on the main 1040 - the software handles all the Schedule 1 connections automatically. But if you're curious (like I was), you can usually view all the generated forms to see how everything flows together. One last tip: if you're just starting out with Schedule C, consider keeping a simple spreadsheet throughout the year with your business income and expenses. It makes filling out Schedule C so much easier when tax time comes around, rather than trying to reconstruct everything from receipts and bank statements. Trust me on this one - I learned it the hard way! Thanks Logan for asking this question - even though I've been doing this for a couple years now, reading through everyone's explanations really reinforced my understanding of the process.
