The Jobs and Growth Tax Relief Reconciliation Act of 2003 (JGTRRA), also commonly referred to as the Bush Tax Cuts, was an economic stimulus package enacted by the United States Congress on May 28, 2003. The goal of the package was to provide tax relief to individuals and businesses, and to stimulate economic growth by boosting consumer spending and business investments.

JGTRRA marked a significant reduction in taxes for all income brackets. The top marginal tax rate was reduced from 38.6% to 35%, while the lowest tax rate was reduced from 15% to 10%. Individuals earning over $300,000 saw their tax burden reduced from 39.1% to 35%. This was the first significant tax cut since 1986.

The Act also included several tax breaks for businesses, including an extension of depreciation rules that allow businesses to write off the costs of their investments over a shorter period of time. This meant that businesses could make investments with lower up-front costs and would recoup their investment more quickly. The Act also allowed companies to immediately write off up to $25,000 of new capital investments, with higher limits for depreciable assets. This was intended to spur businesses to invest more in their operations, increasing their productivity and business development.

The Bush Tax Cuts also reduced taxes on corporate income, with the federal corporate tax rate reduced from 35% to 31%. This allowed businesses to increase their profits and hire more workers, which created additional jobs. The change in the tax rate came at a time when the U.S. economy was in a recession and businesses were hesitant to expand and take on more risk.

In addition to cutting taxes and offering corporate incentives, the Act provided for an extension of unemployment benefits for those who had been out of work for an extended period of time. It also extended the expired tax credits for college expenses, allowing for further tax breaks for those paying for college tuition.

The overall purpose of the Jobs and Growth Tax Relief Reconciliation Act of 2003 was to jump start the economy by providing tax relief to individuals and businesses, and encouraging increased business investment. The Act was successful in its goal, creating nearly two million jobs and reducing corporate taxes, thus helping boost the economy. Despite mixed opinions of the long-term economic effects, the Act was credited with reducing the unemployment rate and eliminating the budget deficit.
