This legislation, the Tribal Tax and Investment Reform Act of 2025, aims to achieve tax parity for Indian Tribal Governments by treating them similarly to State governments for various federal tax purposes. It seeks to foster tribal self-governance and economic development by amending the Internal Revenue Code of 1986. A key provision repeals the "essential governmental function" requirement for tribal excise tax exemptions and establishes a national bond volume cap of $400 million for tax-exempt bonds issued by Indian Tribal Governments, with inflation adjustments and geographic flexibility for qualified Indian lands. These bonds, however, cannot be used to finance gaming facilities.

The bill also introduces a separate national limitation of $45 million for "Alaska Native Corporation Economic Development Bonds," treated similarly to State-issued bonds and also excluding gaming. Existing "tribal economic bonds" will terminate by December 31, 2028. Regarding pension and employee benefit plans, the bill includes Indian tribal governments in key definitions like "governmental plan" and "qualified public safety employee," and grandfathers certain existing tribal deferred compensation plans. An enforcement moratorium is placed on tribal plans related to the Pension Protection Act of 2006 until regulations are issued.

Crucially, the Act establishes uniform protections and fiduciary standards for Tribal pension plans with at least 500 active participants. These standards impose personal liability on fiduciaries, mandate non-discrimination, and require summary plan descriptions, with enforcement actions possible in tribal or federal courts. The legislation also extends governmental unit status to Indian tribal governments for charitable contribution deductions and for supporting organizations of public charities.

The bill enhances Tribal child support enforcement agencies by applying Social Security Act provisions and including tribes as "States" for IRS tax refund offsets. Indian tribal governments are recognized for determining special needs children under the federal adoption credit. To stimulate investment, an additional annual New Markets Tax Credit allocation of $175 million is created specifically for "qualified tribal area investments," with a program for educational and technical assistance.

The legislation includes "Indian areas" as difficult development areas for the Low-Income Housing Tax Credit, provided projects meet specific tribal financing or sponsorship criteria. It clarifies that "Indian general welfare benefits" are excluded from income for Supplemental Security Income (SSI) calculations, and certain tribal grantor trusts are excluded from SSI resources. Finally, the Act makes the Indian Employment Tax Credit permanent, increases its maximum limit to $30,000, and excludes payments from the Indian Health Service Loan Repayment Program and Indian Health Professions Scholarships Program from gross income.
