End Notes
[1] It is important to note that Republicans chose to make the corporate provisions permanent. Compared to the provisions that expire, these permanent corporate provisions skew even more heavily in favor of the very wealthy, with 83 percent of their benefit flowing to people in the top 1 percent by income.

The bipartisan legislation proposed staggered improvements over three years: 2023, 2024, and 2025. We estimated that more than 80 percent of children left out of the full credit would have seen their credit rise in the first year of the expansion, and that 500,000 children would have seen their families’ incomes rise above the poverty line when the proposal was fully in effect in 2025.

We project 2026 tax parameters using Bureau of Labor Statistics (BLS) data on the consumer price index (CPI-U) and chained consumer price index (C-CPI-U), and Congressional Budget Office (CBO) projections of the C-CPI-U. We adjust incomes to 2026 levels in several ways: we assume earnings grow at the rate of wages and salaries plus proprietors' income per employed person aged 16 and over in Bureau of Economic Analysis (BEA) income data through 2024, BLS employment data through 2024, and CBO income and employment projections for 2026; we assume rental, interest, and dividend income grow at their rate of growth per person aged 16 and over in BEA income data through 2024 and CBO income and population projections for 2026; and we adjust all other income for changes in the CPI-U using BLS data through 2024 and CBO projections for 2026.

Treasury’s analysis reflects the Biden Administration’s pledge not to raise taxes for people making up to $400,000 a year. Its estimates of reversing the tax cuts for people with incomes above $400,000 include certain tax changes that would modestly increase tax rates for households in the top 1 percent (those with incomes over $743,247) relative to allowing all the tax cuts to fully expire. For example, the 2017 tax law’s revenue-raising provisions are assumed to be extended for all income levels rather than being allowed to expire.

[31] The January 2024 House-passed expansion of the Child Tax Credit included provisions that would have made the credit more available to children in families with low and moderate incomes — providing the credit on a per-child basis and eventually eliminating the refundability cap. (See “Child Tax Credit” section above for details.) We estimate the marginal cost of implementing these provisions for ten years (2026-2035), assuming that the extension of the 2017 tax law changes to the Child Tax Credit would be accounted for elsewhere, using the 2015 IRS Statistics of Income Public Use File. The January 2024 expansion also included a provision to index the maximum credit and refundability cap amounts to inflation, which would add roughly $190 billion over ten years.
