Federal Tax Code Assumptions

• Tax Base = All income from whatever source derived
• Standard deduction = $12,000 single / $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 – assume these tax rates apply to taxable income from all income sources (no special rate for capital gains)

Tax Rate	Single Filer	Married Filing Jointly
10%	$0 - $10K	$0 - $20K
12%	$10K+ - $40K	$20K+ - $80K
22%	$40K+ - $85K	$80K+ - $170K
24%	$85K+ - $160K	$170K+ - $320K
32%	$160K+ - $205K	$320K+ - $410K
35%	$205K+ - $510K	$410K+ - $610K
37%	$510K+	$610K+

State Tax Code Assumptions

• Tax base = federal AGI
• State income tax rate = 4.85%
• Filers can claim a tax credit equal to the sum of 6% of itemized or standard deduction claimed plus $500 per dependent child. This tax credit phases out 2.5 cents for each dollar of AGI above $30,000 single and $60,000 married filing jointly.
