If you made $24,000 in profit as a self-employed person, here’s how your federal taxes should look for 2023 (I’m assuming you’re single and not a head of household):

Net Profit: $24,000
Self-Employment Tax: $3,391
Standard Deduction: -$13,850
SE Deduction: -$1,695
AGI: $8,455
Income tax: $845.50
Effective income tax rate: 3.5%
Effective SE tax rate: 14.2%
Total effective tax rate: 17.7%

(I’m not a tax preparer - please don’t use these numbers to file your taxes.)

Where you’re feeling the pinch is your Social Security and Medicare taxes, not your income tax. Given how small your profits were, there’s no real way to offset this except by making your business even less profitable.
