What the policy did

Sequenced supply-side tax programme enacted under budget reconciliation with sunset provisions. The Economic Growth and Tax Relief Reconciliation Act 2001 (EGTRRA) cut all statutory individual income-tax rates (top rate 39.6% to 35%), created a new 10% bottom bracket, doubled the child tax credit to $1,000, phased out the estate tax through 2010, and expanded IRA/401(k) limits. The Jobs and Growth Tax Relief Reconciliation Act 2003 (JGTRRA) accelerated the 2001 rate cuts, cut the long-term capital gains rate to 15%, and reduced the top dividend rate to 15% (from ordinary-income treatment). Stated case: boost investment, move toward consumption-tax treatment of capital income, and return budget surpluses to households. Ten- year revenue cost roughly $1.7T (EGTRRA) + $350B (JGTRRA) on CBO scoring; combined with post-9/11 defence and Medicare Part D spending, converted the inherited surplus into structural deficit by mid-decade.

Policy-content fingerprint — what this policy moved, on which axes

Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.

intended
tax progressivity
fiscal.tax_progressivity
Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).
decreased · strong
less progressive (flatter rates, compression, smaller credits)
Top rate 39.6% → 35%; estate tax phase-out; dividend tax cut tilted toward top deciles.
tax capital
fiscal.tax_capital
Taxation of capital income (dividends, capital gains, inheritance, wealth). Distinct from corporate rate.
decreased · strong
lower capital income tax
LTCG 20% → 15%, dividends to 15%, estate phase-out.

Statutory and effective corporate tax rates, treatment of depreciation, and international competitiveness.
unchanged · weak
Statutory corporate rate unchanged at 35%; bonus depreciation introduced.
spending level
fiscal.spending_level
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
increased · moderate
higher spending share
Simultaneous defence + Medicare Part D expansion widened structural deficit.
