Federal Tax Code Assumptions

$,$ Tax Base $=$All income from whatever source derived

Standard deduction $=$$$12,000$ single $\frac{?}{?}$$$24,000$ married filing jointly

Taxpayer can claim deductions per IRS Form $1040$ and related schedules

Additionally, filers can claim a child tax credit of $$3,000$ per dependent child. This tax credit phases out $15$ cents for every dollar of AGI above $$150K$ single and $$250K$ married filing jointly.

Federal tax brackets $-$ For this question, assume these tax rates apply to taxable income from all income sources $($no special rate for capital gains$)$
