First time filing taxes for my side hustle - shocked at how much I'm paying! Need help understanding

What you're experiencing is the shock of self-employment taxes! The 15.3% you mentioned is just the self-employment tax portion (Social Security and Medicare), which is essentially the employer and employee portions combined since you're both when self-employed. But that's not the only tax you're paying. You also owe regular income tax on your profits. The software is calculating both your self-employment tax AND adding your business profit to your regular income for income tax purposes. Have you entered all your business expenses yet? This is crucial! Your self-employment taxes are calculated on your net profit (income minus expenses), not gross income. Make sure you're deducting everything legitimate - home office if applicable, supplies, software subscriptions, any travel for business, portion of phone/internet used for business, etc. Also, when you have self-employment income, you generally should be making quarterly estimated tax payments throughout the year. Since you didn't, that might be why the hit seems so big all at once.

I went through the same painful discovery last year! After trying multiple tax software programs and getting confused by different results, I discovered taxr.ai (https://taxr.ai) which really helped me understand what was happening with my side business taxes. What I learned was that the software wasn't wrong - I was just missing some key deductions. The platform analyzed my bank statements and found a bunch of business expenses I hadn't even considered. It also explained exactly how self-employment taxes work and why my tax bill seemed so high. For me, the real issue was not having separated my business and personal expenses throughout the year. One tip - make sure you're tracking mileage if you drive for your business at all. That deduction alone saved me hundreds!

Just wanted to update after trying taxr.ai from the recommendation above! I was in the same boat as the original poster - completely shocked at my tax bill for my side business. After uploading my documents, it found over $3,800 in deductions I was missing! The biggest things it caught were my home internet (partial business use), software subscriptions I'd forgotten about, and some professional development courses I took last year. It explained that I needed to keep better records of business vs. personal expenses and showed me exactly how my self-employment tax was calculated. My tax bill went from terrifying to manageable. The explanation of quarterly payments for 2025 was super helpful too - definitely not making that mistake again!

If you're still struggling after entering all your expenses, you might need to talk directly to someone at the IRS to make sure you're filing correctly. I tried calling them for weeks when I had a similar issue and it was IMPOSSIBLE to get through. Then I found this service called Claimyr (https://claimyr.com) that got me connected to an actual IRS agent in about 15 minutes when I'd been trying unsuccessfully for days. They have a demo video here: https://youtu.be/_kiP6q8DX5c The IRS agent I spoke with explained that I was miscategorizing some of my income and expenses, which was causing my tax calculation to be way off. They walked me through the correct way to file my Schedule C and it made a huge difference in my final tax bill.

I owe everyone here an apology, especially about my comment on Claimyr. I was having a terrible day dealing with my own tax nightmare and took it out inappropriately here. After my frustration hit a breaking point yesterday, I actually tried the service myself. I had been trying to reach the IRS for THREE WEEKS about a similar small business tax issue. Using Claimyr, I got through to an agent in 27 minutes while I was cooking dinner. The agent confirmed I was calculating my self-employment tax correctly but identified that I had made an error in how I was reporting my business income across multiple platforms. Sometimes being proven wrong is the best thing that can happen. Sorry for the skepticism and thanks for the recommendation that actually saved me from a much bigger headache.

Make sure you're considering the QBI (Qualified Business Income) deduction too! As a self-employed person, you likely qualify for a deduction of up to 20% of your qualified business income. The tax software should calculate this automatically, but sometimes you need to make sure you've checked the right boxes. Also, don't forget to look into retirement options like a SEP IRA or Solo 401(k) which can significantly reduce your taxable income. Even though it's after December 31st, you can still open and fund many retirement accounts for the previous tax year before the filing deadline.

I think you might be confusing two different things. The 15.3% is JUST your self-employment tax (Social Security and Medicare). But you still have to pay regular income tax on top of that! Try this rough calculation: 1. Take your business gross income 2. Subtract ALL business expenses 3. That's your business profit 4. Pay 15.3% self-employment tax on that profit 5. ALSO add that profit to your regular income 6. Pay regular income tax on your combined income That's why it feels like you're being taxed twice - because you kind of are! Welcome to self-employment! 😫
