The Office of Tax Analysis (OTA) advises and assists the Assistant Secretary (Tax Policy) and his deputies in the development, analysis, and implementation of tax policies and programs. The Office provides economic and policy analyses leading to development of the Administration's tax proposals, assesses major Congressional tax proposals, and analyzes the effects of existing laws. OTA is responsible for official Administration estimates of all Federal receipts included in the President's Budget and Mid-Session Review, and revenue estimates for actual and proposed tax legislation, earmarked revenue allocated to various trust funds, Treasury cash management decisions, and the Tax Expenditure Budget.
OTA works closely with the other divisions of the Office of Tax Policy (OTP) to develop legislative proposals and regulations. Staff members are active researchers, producing economic research in all areas related to domestic and international tax policy, often in collaboration with academic economists. OTA develops and operates several major microsimulation models and maintains large statistical databases to analyze the economic, distributional, and revenue effects of alternative tax proposals and tax systems. OTA assists the IRS in conducting studies of tax compliance and taxpayer compliance burdens, developing and revising tax forms and, alongside OTP staff, in formulating and reviewing tax regulations. OTA staff engage in tax treaty negotiations with foreign governments and participate in meetings of international organizations.
Gregory Leiserson, Deputy Assistant Secretary (Tax Analysis), provides advice and economic analysis to the Assistant Secretary and oversees the work of the Office of Tax Analysis.
The Director, Edith Brashares, leads the activities of the economists and statisticians in the five divisions of OTA.
The Business and International Taxation Division, directed by Neviana Petkova, provides economic analyses and conducts research on tax provisions affecting corporations, partnerships and other unincorporated businesses, financial institutions and products, and energy and the environment, including taxes on income, consumption, and capital income, and business excise taxes. The division analyzes and researches the taxation of both income earned outside the United States by U.S. citizens, residents, and domestic corporations and income earned within the United States by foreign corporations and nonresidents.
The Economic Modeling and Computer Applications Division, directed by Robert Gillette, develops and maintains several major simulation models which are used to provide estimates and analyses of changes in current or proposed tax legislation. The five major modeling systems are: the individual income tax model, the corporate tax model, the corporate panel model, the depreciation model, and the estate tax model. The Division continually works to develop new data sources and improve simulation methodologies to meet Office of Tax Policy needs.
The Individual Taxation Division, directed by Adam J. Cole, develops policy proposals and provides analysis of the impact of existing and proposed individual income tax provisions on economic activity and welfare, marginal tax rates, and the distribution of the tax burden among families. The Division is responsible for policy development and analysis of payroll taxes, excise taxes, estate and gift taxes, and nonprofit organizations. Policy issues include the structure of tax rates, the tax treatment of different types of families, savings incentives, the tax treatment of pensions and health insurance, education incentives, tax-exempt bonds, and income tax compliance.
The Business and Individual Revenue Divisions, directed by Curtis Carlson and J. Scott Jaquette, respectively, produce estimates of revenue changes associated with the Administration’s, as well as major Congressional, tax proposals. These estimates are used to evaluate the proposals and assist in determining related Administration policy positions. The Divisions also provide the official Administration forecasts of all Federal receipts and estimates of Tax Expenditures included in the President's Budget and Mid-Session Review. The Divisions provide the Office of the Fiscal Assistant Secretary with monthly receipts forecasts for use in determining the timing and size of government borrowing, and calculate amounts to be deposited into numerous federal trust funds.
