Family of four in San Diego, Calif.
-- $150,000 income
-- Married couple with two children under 17
-- Homeowners
-- Itemized deductions today total $22,000 ($7,000 state/local income tax; $5,000 property tax; $8,000 mortgage interest; $2,000 charitable contributions)
[redThe family would save an estimated $3,559 in federal income taxes:
They would no longer itemize, opting instead to take the nearly doubled $24,000 standard deduction for joint filers. Their top tax rate would drop to 22% from 25% today. And they would become newly eligible to take the expanded Child Tax Credit ($2,000 per child).
The Tax Institute ran another example of a married couple in Houston -- with three kids under 17 -- also making $150,000 and found they'd save a little more ($3,771) on their tax bill for the same reasons.
