# Reagan Tax Cuts (August 13, 1981)
On **August 13, 1981**, President Reagan signed the **Economic Recovery Tax Act of 1981 (ERTA)** — the largest tax cut in American history at that time — reducing the top marginal income tax rate from **70% to 50%** (later to **28%** via the Tax Reform Act of 1986), cutting capital gains taxes, accelerating business depreciation, and indexing tax brackets to inflation. The act was the **first implementation of supply-side economics at the federal level** and the fulfillment of the tax-cut ideology that [[Andrew Mellon]] had pioneered in the 1920s.
Reagan's tax cuts matter for the KB as the **moment supply-side economics became Republican orthodoxy** — the policy that every subsequent Republican administration has pursued (Bush 2001/2003, Trump TCJA 2017) and that no Republican has repudiated. The cuts also established the **"starve the beast" strategy**: cutting revenue to create deficit pressure that would force spending cuts to social programs that could not be repealed directly. The Heritage Foundation, Cato Institute, and the think tank infrastructure built in response to the [[Powell Memo]] provided the intellectual justification.
## What ERTA Did
### Rate Cuts
- Top marginal rate: **70% → 50%** (phased over three years)
- All brackets reduced by ~25%
- The 1986 Tax Reform Act further reduced the top rate to **28%** (while broadening the base)
### Business Provisions
- **Accelerated Cost Recovery System (ACRS):** Dramatically shortened depreciation schedules, providing immediate tax benefits to capital-intensive businesses
- **Investment tax credits** expanded
- **Safe harbor leasing:** Allowed profitable companies to buy unused tax benefits from unprofitable ones (repealed in 1982 after public backlash)
### Estate Tax
- Estate tax exemption raised from $175,000 to $600,000
- Maximum estate tax rate cut from 70% to 55%
- Unlimited marital deduction introduced
## The Mellon Parallel
Reagan explicitly invoked the Coolidge-Mellon era as his model. The parallel is precise:
| Element | Mellon (1920s) | Reagan (1980s) |
|---------|---------------|----------------|
| Top rate cut | 73% → 24% | 70% → 28% |
| Theory | Wealth trickles down; revenue increases | Supply-side: tax cuts pay for themselves |
| Boom | Roaring Twenties | 1980s expansion |
| Deficit/consequence | Speculative bubble → [[Black Tuesday]] | Deficit tripled ($79B → $221B); national debt tripled |
| Who benefited | Top 1% income grew 75% | Top 1% income grew 87% (1981–1989) |
| Stated justification | "Scientific taxation" | "[[Laffer Curve]]" |
The key difference: Mellon's cuts produced budget surpluses (temporarily) because the 1920s government was small. Reagan's cuts produced **massive deficits** because the modern state was large — which was, for some conservative strategists, the point.
## "[[Starve the Beast]]"
The deficits the tax cuts produced were not an accident for all of Reagan's advisors. The **"starve the beast"** theory — attributed to various conservative strategists including [[David Stockman]] (initially) and [[Grover Norquist]] (later) — held that:
1. Tax cuts reduce revenue
2. Reduced revenue creates deficit pressure
3. Deficit pressure forces spending cuts
4. Spending cuts shrink the programs (Social Security, Medicare, Medicaid) that could not be repealed directly
Whether Reagan himself fully embraced this logic is debated. Budget Director David Stockman later admitted that the supply-side projections were "a Trojan horse" for reducing the top tax rate, and that the deficits were foreseeable.
## Consequences
### The Deficit Explosion
- Federal deficit: $79 billion (1981) → $221 billion (1986)
- National debt: $994 billion (1981) → $2.9 trillion (1989)
- Reagan raised taxes in 1982 and 1984 to partially offset the revenue loss, but never came close to closing the gap
### Income Inequality
- The top 1%'s share of national income began its modern climb (from ~8% in 1981 to ~13% by 1989, eventually reaching ~20% by the 2020s)
- Real wages for the median worker stagnated; the gains accrued overwhelmingly to the top
- This is the beginning of the inequality trajectory that fueled both left-wing populism (Sanders, Warren) and right-wing populism (Trump) decades later
### Policy Lock-In
Reagan's tax cuts created a political equilibrium that has proven nearly impossible to reverse:
- Every Republican president since has cut taxes (Bush 2001/2003, Trump 2017)
- No Democrat has restored pre-Reagan top rates (Clinton raised to 39.6%; Obama maintained)
- Grover Norquist's [[Taxpayer Protection Pledge]] (1986) made tax increases a career-ending move for Republicans
## The Through-Line
| Cycle | Tax cut | Top rate after | Boom | Bust | Deficit impact |
|-------|---------|---------------|------|------|----------------|
| Mellon | Revenue Acts 1921–28 | 24% | Roaring Twenties | 1929 crash | Surpluses (small government) |
| **Reagan** | **ERTA 1981 + TRA 1986** | **28%** | **1980s expansion** | **S&L crisis, 1990 recession** | **Debt tripled** |
| Bush | EGTRRA/JGTRRA 2001/03 | 35% | Housing bubble | 2008 financial crisis | Surplus → deficit |
| Trump | TCJA 2017 | 37% | Pre-COVID growth | COVID + inflation | $1.9T added (CBO est.) |
