Establishes a billionaire mark-to-market tax

This bill would impose a new tax on New York State residents with $1 billion or more in net assets (total wealth minus debts), calculated as if they sold all assets at market value on December 31, 2024. Taxpayers would pay the resulting tax over 10 years with an annual interest-like fee, or in full for the 2025 tax year. It includes credits for taxes paid to other states on assets accumulated before New York residency, and excludes certain assets like gifts made within five years. The tax applies only to New York residents meeting the $1 billion threshold, with the first payment due for the 2025 tax year. The bill is currently pending in the Budget and Revenue committee.
