First Time Filing for Small Business Taxes - Why Am I Paying So Much?
I started a freelance business on the side last year, just a small operation that I run by myself. In 2024, I earned about $19k from this side hustle. When I initially did my taxes using one of those online tax software programs, it estimated I'd get back around $2.2k from my regular job. I was pretty happy with that refund since I figured it would help cover whatever I'd owe for my business. But then when I entered my 1099-K information into Schedule C (before even deducting any expenses), my estimated refund changed to owing almost $4k! This seems excessive and I'm totally confused. I've been reading online that small businesses typically pay around 15.3% self-employment tax on gross income. If that's true, I should only owe about $2,900 on my $19k gross, right? So why is the software saying I owe more like $6k total? I feel like I must be missing something obvious here. This is my first time dealing with business taxes, as my side gig really took off this year. Can anyone explain what's happening or what I might be doing wrong? Please be gentle with explanations - I'm completely new to Schedule C and self-employment taxes.

What you're experiencing is the reality of self-employment taxes combined with regular income tax. The 15.3% you mentioned is JUST the self-employment tax portion (Social Security and Medicare taxes that both employees and employers pay - when you're self-employed, you pay both halves). You're also paying regular income tax on that business income too! Your $19k freelance income gets added to your regular job income, which might be pushing you into a higher tax bracket overall. The good news is that you haven't entered your business expenses yet! Make sure you claim EVERY legitimate business expense - software subscriptions, portion of internet/phone used for business, office supplies, equipment, professional development, etc. This will reduce your net business income, which lowers both your self-employment tax AND regular income tax. Also, don't forget you can deduct half of your self-employment tax on your 1040, which helps a bit too.

•Thanks for the explanation, that makes more sense now. But I'm still a bit confused - if I made $19k from freelancing, and say I have $5k in legitimate business expenses, so my net profit is $14k... how do I calculate approximately what I'll owe? Do I pay the 15.3% on the $14k PLUS some additional percentage for regular income tax?

•You'll pay 15.3% self-employment tax on your net profit of $14k, which would be about $2,142. Then you'll also pay regular income tax on that $14k at your marginal tax rate, which depends on your total income including your day job. If you're in, say, the 22% tax bracket when combining all your income, you'd pay an additional $3,080 in income tax on that $14k (though this is simplified - tax brackets are progressive). So total tax impact could be around $5,222 on your $14k net profit. But you'll also get to deduct half your self-employment tax, which reduces your taxable income a bit.

I went through the exact same panic attack last year when I started my side business! Taxes hit hard when you're self-employed. I spent hours trying to figure out how to handle my Schedule C and still felt lost. Then I discovered https://taxr.ai which literally saved me thousands. I uploaded my 1099-K and bank statements, and it automatically categorized all my business expenses and even found deductions I had no idea about! The AI explained exactly how self-employment taxes work and showed me which expenses were legitimate deductions. Super helpful for first-timers like us who don't know what we're doing. After using it, my tax bill dropped by almost $2k because I was claiming all the right deductions. It walks you through the whole Schedule C process so you understand what you're doing.

•Does it actually work with other tax software? Like can I use this and then take the info to TurboTax or whatever? I'm worried about using too many different systems and messing something up.

•I'm kinda skeptical about AI tax tools. Has anyone else actually used this? How do you know it's not missing something important that would get you in trouble with the IRS?

•Yes, it works alongside whatever tax software you already use. It helps identify all your deductions and expenses, then you just enter those amounts into TurboTax or whatever you're using. It's not a replacement for your tax filing software - it's more like a smart assistant that makes sure you're getting all your deductions right. As for reliability, it actually explains the tax code rules for each deduction it suggests, so you can verify everything. It was designed by tax professionals and cites the specific IRS rules it's using. I found it much more thorough than trying to figure out deductions on my own or just trusting whatever TurboTax suggested.

I wanted to follow up about my experience with taxr.ai since I was skeptical in my earlier comment. I decided to give it a try with my lawn care side business, and wow - it found over $3k in deductions I was missing! The mileage tracking alone saved me hundreds, and it helped me properly calculate the business percentage of my phone and internet bills. What really impressed me was how it explained each deduction in plain English and showed me exactly where to put the numbers on my Schedule C. The receipt scanning feature organized all my expenses automatically, which saved me hours of work. For anyone new to self-employment taxes, it's definitely worth checking out. Completely changed my understanding of business deductions.

I had a similar issue when I started my photography business. The tax situation was insane! After weeks of trying to get through to the IRS for clarification on deductions, I found https://claimyr.com which got me connected to an actual IRS agent in under 15 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c I was honestly shocked when I got through that quickly after spending hours on hold myself. The IRS agent I spoke with explained exactly how self-employment taxes work with my regular income and walked me through which expenses were legitimate business deductions for my situation. Totally worth it to get official answers directly from the source.

•Wait I'm confused. What is this exactly? Is this something that helps you talk to real IRS people? How does that even work? The IRS never answers their phones...

•Yeah right. There's no way this actually works. I've tried calling the IRS like 50 times this year and never got through. They keep you on hold forever then disconnect you. I'm calling BS on this one.

•It's a service that navigates the IRS phone system for you and waits on hold in your place. When they reach an actual IRS representative, they call you to connect you directly with the agent. It basically handles all the frustrating hold time so you don't have to. The reason it works is they have specialized technology that stays on hold for you 24/7, using optimal calling times and methods to get through. It's not magic - they're just better at getting through the phone system than individuals are. Trust me, I was completely skeptical too until I tried it. I wasted days trying to get through on my own before using this.

I need to publicly eat my words from my skeptical comment! After seeing more people recommend Claimyr, I tried it yesterday out of desperation since I had a complicated question about my business deductions. Within 27 minutes (they texted updates while on hold), I was actually talking to a real live IRS person! The agent helped me understand exactly how my business income affects my tax brackets and confirmed which expenses were legitimate for my specific situation. Got everything resolved in one call instead of stressing for weeks. I seriously can't believe it worked after wasting so many hours trying to call myself. Totally changed my approach to dealing with tax questions.

Something nobody's mentioned yet - make sure you're setting aside money for quarterly estimated tax payments for 2025! That was my biggest mistake my first year freelancing. I had a similar situation last year and got hit with underpayment penalties because I didn't realize I needed to make quarterly payments. When you're self-employed, you should be paying taxes throughout the year, not just at filing time. It's a whole different system than W-2 employment where taxes are automatically withheld.

•Yikes, I had no idea about quarterly payments! How do I figure out how much to pay each quarter? And are there specific deadlines I need to know about?

•You'll need to estimate your annual tax liability and divide by four. The easiest approach is to pay 100% of last year's tax liability (or 110% if you make over $150k) divided into four equal payments. The quarterly due dates are April 15, June 15, September 15, and January 15 of the following year. You can make payments online through the IRS website using Form 1040-ES. Set calendar reminders so you don't forget - the penalties for missed quarterly payments can add up quickly!

Has anyone here used QuickBooks Self-Employed? My tax person recommended it for tracking expenses and estimating quarterly taxes. Wondering if its worth the monthly fee or if theres something better out there?

•I've been using it for my consulting business for 2 years. Pretty good for the basics - it connects to your bank account, helps categorize expenses, and tracks mileage. The quarterly tax estimator is handy too. It's not perfect, but makes tax time way easier if you keep up with it throughout the year.
