IMPORTANT TAX ANNIVERSARIES: ERTA'S 25th AND INDEXING'S 20th

August 13 marks the twenty-fifth anniversary of
President Reagan's signing  of the Economic
Recovery Tax Act of 1981 (ERTA). That Act
reduced marginal personal income tax rates across
the board, phased in over four calendar years, to
increase incentives to work, save, and invest. ERTA
also introduced tax indexing, the practice of
adjusting  personal  exemptions, the  standard
deduction, and the tax brackets for inflation each
year to keep inflation-driven income increases from
pushing taxpayers into higher tax brackets. That
provision was effective in 1985. When people filed
their tax forms in April 2006, it was the twentieth
time that they received the protection that indexing
offers against bracket creep. ERTA's rate cuts and
indexing were part of the Reagan economic policy
that brought an end to the stagflation of the 1970s,
and led to a seven-year expansion that created some
eighteen million jobs. Many tax rate changes have
been enacted since, some for the better, others not.
The indexing feature is the last remaining, largely
unchanged, major piece of the original 1981 tax cut,
and one of the most important for economic growth
and job creation.
The 1970s Problem: Stagflation
During the 1970s and the start of the 1980s, the
United States experienced a period of stagflation,
which is slow economic growth combined with
inflation.  Four recessions marked   the  era.
Unemployment trended up. Inflation and interest
rates soared well into double digits. Real after-tax
wages were falling. Each business cycle through
1980 seemed to leave us worse off. (See chart 1.)

The Keynesian economic theory of the time
could not offer a solution. It viewed all economic
policies as working by increasing or decreasing
aggregate demand. To fight inflation, government
would raise taxes, cut its spending, and slow the
growth of the money supply, all policies set on
stop to reduce private or public sector spending on
goods and services. GDP would be expected to slow
and unemployment to rise in the process, until
inflationary expectations were wrung out of the
system. To fight unemployment, the government
would cut taxes, increase its spending, and create
money at a faster pace, all policy tools set on go.
Inflation would be expected to increase, lowering
real wages to encourage hiring. This trade-off, that
there had to be more inflation to get lower
unemployment, was known as the Phillips Curve,
which helped put the dismal in the Dismal Science.
The Insight: Inflation-Driven Tax Rates Were
Strangling Hiring and Investment
At the time, there were fifteen taxable brackets
for a married couple, with tax rates ranging from 14
percent to 70 percent (capped at 50 percent on
wages). The dollar amounts that separated one tax
bracket from another were not adjusted for inflation.
Neither were the personal exemption and the
standard deduction. The brackets were not very
wide in percentage terms, especially compared with
double digit inflation. With inflation and a cost of
living increase, more of a worker's income was
subject to tax, and the taxable portion spilled over
into higher tax rate brackets. Average and marginal
tax rates rose.
