in revenue as a share of GDP. The study did not examine the longer-term impact of Reagan tax policy, including sunset clauses and "the long-run, phased-in effect of the tax bills". The fact that tax receipts as a percentage of GDP fell following the Economic Recovery Tax Act of 1981 shows a decrease in tax burden as share of GDP and a commensurate increase in the deficit, as spending did not fall relative to GDP. Total federal tax receipts increased in every Reagan year except 1982, at an annual average rate of 6.2% compared to 10.8% during the preceding eight years. The effect of Reagan's 1981 tax cuts (reduced revenue relative to a baseline without the cuts) were at least partially offset by phased in Social Security payroll tax increases that had been enacted by President Jimmy Carter and the 95th Congress in 1977, and further increases by Reagan in 1983 and following years, also to counter the uses of tax shelters. An accounting indicated nominal tax receipts increased from $599 billion in 1981 to $1.032 trillion in 1990, an increase of 72% in current dollars. In 2005 dollars, the tax receipts in 1990 were $1.5 trillion, an increase of 20% above inflation. Debt and government expenditures Reagan was inaugurated in January 1981, so the first fiscal year (FY) he budgeted was 1982 and the final year was 1989. During Reagan's presidency, the federal debt held by the public nearly tripled in nominal terms, from $738 billion to $2.1 trillion. This led to the U.S. moving from the world's largest international creditor to the world's largest debtor nation. Reagan described the new debt as the "greatest disappointment" of his presidency. The federal deficit as percentage of GDP rose from 2.5% of GDP in fiscal year 1981 to a peak of 5.7% of GDP in 1983, then fell to 2.7% GDP in 1989. Total federal outlays averaged of 21.8% of GDP from 1981–88, versus the 1974–1980 average of 20.1% of GDP. This was the highest of any President from Carter through Obama. Total federal revenues averaged 17.7% of GDP from 1981–88, versus the 1974–80 average of 17.6% of GDP. Federal individual income tax revenues fell from 8.7% of GDP in 1980 to a trough of 7.5% of GDP in 1984, then rose to 7.8% of GDP in 1988.
