Paying a Fair Share Act of 2017

Introduced April 27, 2017

AI-Generated Summary

Updated April 15, 2026 at 3:00 PM UTC

The Paying a Fair Share Act of 2017 adds a new federal tax that applies to individuals, estates and trusts whose adjusted gross income exceeds $1 million (adjusted for inflation). The tax is meant to make high‑income earners pay a larger share by imposing an extra amount roughly equal to 30 % of the income they earn above a modified charitable‑deduction limit, and then scaling it based on how far their income is above the $1 million threshold. The rule takes into account regular income tax, payroll taxes and other credits, and it takes effect for tax years beginning after December 31, 2017.

Key Provisions

  • Creates a new “fair share tax” (Section 59A) in the Internal Revenue Code for high‑income taxpayers.
  • Defines a high‑income taxpayer as anyone (other than a corporation) with adjusted gross income over $1 million (or $500,000 for married filing separately), adjusted each year for inflation.
  • Calculates a tentative tax equal to 30 % of the amount by which the taxpayer’s income exceeds a modified charitable‑contribution deduction.
  • Applies the tentative tax multiplied by a fraction that reflects how much the taxpayer’s income exceeds the $1 million threshold, capping the fraction at 1 (i.e., a phased‑in increase).
  • Includes regular income tax, payroll taxes, and other credits in the calculation, and excludes the new tax from certain credit limitations.
  • Effective for taxable years beginning after December 31, 2017.

Sense of the Senate regarding tax reform

It is the sense of the Senate that—

(1)

Congress should enact tax reform that repeals unfair and unnecessary tax loopholes and expenditures, simplifies the system for millions of taxpayers and businesses, and makes sure that the wealthiest taxpayers pay a fair share; and

(2)

this Act is an interim step that can be done quickly and serve as a floor on taxes for the highest-income taxpayers, cut the deficit by billions of dollars a year, and help encourage more fundamental reform of the tax system.
