Yes.
It's complicated. Hence, the "simple answer".
$2400 x 12 = $28800 - 14034** = $14766 taxable income equals $1583 tax from the tax table.
1583/14766 = 10.7%.
Self employment tax (SET) is 92.35% of 15..3% = 14.1%
14.1 + 10.7 = ~25%.
Any additional income (over $2400/Mo) will be tax at 26% (12 + 14.1)
**Your $12,000 standard deduction plus your self employment tax deduction (half your SET).
