The U.S. Congress charged the National Academies with conducting a review of the Internal Revenue Code to identify the types of and specific tax provisions that have the largest effects on carbon and other greenhouse gas emissions and to estimate the magnitude of those effects. To address such a broad charge, the National Academies appointed a committee composed of experts in tax policy, energy and environmental modeling, economics, environmental law, climate science, and related areas. For scientific background to produce Effects of U.S. Tax Policy on Greenhouse Gas Emissions, the committee relied on the earlier findings and studies by the National Academies, the U.S. government, and other research organizations. The committee has relied on earlier reports and studies to set the boundaries of the economic, environmental, and regulatory assumptions for the present study. The major economic and environmental assumptions are those developed by the U.S. Energy Information Administration (EIA) in its annual reports and modeling. Additionally, the committee has relied upon publicly available data provided by the U.S. Environmental Protection Agency, which inventories greenhouse gas (GHG) emissions from different sources in the United States. The tax system affects emissions primarily through changes in the prices of inputs and outputs or goods and services. Most of the tax provisions considered in this report relate directly to the production or consumption of different energy sources. However, there is a substantial set of tax expenditures called "broad-based" that favor certain categories of consumption-among them, employer-provided health care, owner-occupied housing, and purchase of new plants and equipment. Effects of U.S. Tax Policy on Greenhouse Gas Emissions examines both tax expenditures and excise taxes that could have a significant impact on GHG emissions.

There is no consensus on how strongly the Tax Cuts and Jobs Act (TCJA) has stimulated U.S. private fixed investment. Some argue that the business tax provisions spurred investment by cutting the cost of capital. Others see the TCJA primarily as a windfall for shareholders. We find that U.S. business investment since 2017 has grown strongly compared to pre-TCJA forecasts and that the overriding factor driving it has been the strength of expected aggregate demand. Investment has, so far, fallen short of predictions based on the postwar relation with tax cuts. Model simulations and firm-level data suggest that much of this weaker response reflects a lower sensitivity of investment to tax policy changes in the current environment of greater corporate market power. Economic policy uncertainty in 2018 played a relatively small role in dampening investment growth.

Better designed and implemented fiscal regimes for oil, gas, and mining can make a substantial contribution to the revenue needs of many developing countries while ensuring an attractive return for investors, according to a new policy paper from the International Monetary Fund. Revenues from extractive industries (EIs) have major macroeconomic implications. The EIs account for over half of government revenues in many petroleum-rich countries, and for over 20 percent in mining countries. About one-third of IMF member countries find (or could find) resource revenues “macro-critical” – especially with large numbers of recent new discoveries and planned oil, gas, and mining developments. IMF policy advice and technical assistance in the field has massively expanded in recent years – driven by demand from member countries and supported by increased donor finance. The paper sets out the analytical framework underpinning, and key elements of, the country-specific advice given. Also available in Arabic: ????? ??????? ?????? ???????? ???????????: ??????? ????????

Employer's Tax Guide (Circular E) - The Families First Coronavirus Response Act (FFCRA), enacted on March 18, 2020, and amended by the COVID-related Tax Relief Act of 2020, provides certain employers with tax credits that reimburse them for the cost of providing paid sick and family leave wages to their employees for leave related to COVID‐19. Qualified sick and family leave wages and the related credits for qualified sick and family leave wages are only reported on employment tax returns with respect to wages paid for leave taken in quarters beginning after March 31, 2020, and before April 1, 2021, unless extended by future legislation. If you paid qualified sick and family leave wages in 2021 for 2020 leave, you will claim the credit on your 2021 employment tax return. Under the FFCRA, certain employers with fewer than 500 employees provide paid sick and fam-ily leave to employees unable to work or telework. The FFCRA required such employers to provide leave to such employees after March 31, 2020, and before January 1, 2021. Publication 15 (For use in 2021)
