Latest action on S. 1243: Read twice and referred to the Committee on Finance.

Who this affects: This bill mainly affects people with very high incomes who pay less than 30% of their adjusted gross income in covered federal taxes. It can also affect certain trusts and estates. Charitable donors in this income range may see less tax benefit from some giving because the bill counts only a limited charitable deduction.

Why this matters: This bill matters because some very high-income taxpayers may pay less than 30% of their income in covered federal taxes. The bill would make them pay extra tax until they reach that floor, with a phase-in above the income limit. It could raise federal revenue from a narrow group of taxpayers. The exact effect is not stated in the bill and would depend on taxpayer behavior and future tax changes.

Key provisions in S. 1243

  • The bill applies to non-corporate taxpayers with adjusted gross income over $1 million. For married people filing separately, it applies over $500,000.
  • The bill sets a 30% minimum tax target based on adjusted gross income. It first subtracts a limited charitable deduction.
  • Only taxpayers who itemize deductions can count charitable gifts. The bill then reduces that amount using a formula tied to limits on itemized deductions.
  • The bill adds up taxes the taxpayer already pays. This includes regular income tax, any alternative minimum tax, and certain payroll taxes, minus most credits that cannot create a refund.
  • The taxpayer owes extra fair share tax only when the 30% amount is higher than those existing taxes. The extra amount phases in as income rises above the limit.
