WASHINGTON—High-income coastal professionals look likely to emerge as significant winners from the Democrats’ proposed tax agenda, escaping rate increases and regaining a deduction for state and local taxes that was capped at $10,000 in 2017.
The potential result: Many residents of New York, New Jersey, California and other states who make more than the $400,000 threshold that President Biden set for tax increases could end up with tax cuts atop the tax cuts they got four years ago.
