Do you have self-employment income? That is subject to an additional self-employment tax of approx 15%.

This happens when you have self-employed income and have to pay self-employment tax.

At $9,300 your tax rate is 10%. The rest of the tax is self-employment taxes which are assessed at 15.3% of 92.35% of your self-employed income.
