What this bill would do
The "Ultra-Millionaire Tax Act of 2026" proposes amending the Internal Revenue Code of 1986 to implement a new wealth tax. This tax is based on the net value of an individual's taxable assets at the end of each calendar year. The bill establishes specific tax brackets, with a 2 percent rate for assets above $50,000,000 and a higher applicable percentage for assets exceeding $1,000,000,000. It includes specific rules for married individuals, trusts, and non-residents. The Act also provides for information reporting, enforcement through audits, and significant funding for the IRS.

Exclusion of Certain Tangible Personal Property: Tangible personal property valued at $50,000 or less is not included in the taxable assets calculation (Section 2902(b)(1)).
