“TEFRA was the biggest tax increase of the period [1968-2006] measured in constant dollars and as a percentage of GDP.”
Now, I’m sure some of you are asking yourselves: What the hell is TEFRA? Well, we’ll get to that in a moment. First, allow me to bask in the irony and point out that this information will continue to challenge assumptions. Because throughout the course of this article, I’ll also illustrate many other tax increases under Reagan.
And for those of you still convinced that Reaganomics saved the day, how do you explain the tax hikes Reagan enacted throughout the 1980's? I thought tax increases were supposed to kill the economy?
The following table represents the net effects of major legislation enacted during the Reagan Administration on the receipts. This table is from the Reagan’s own Budget of the United States Government report for the fiscal year of 1989.

Clearly, the Economic Recovery Tax Act of 1981 had the greatest negative impact on the receipts because this Act was Reagan's huge tax cut package. However, the Tax Reform Act of 1986 was his historic Act that most people are familiar with. This was the legislation that had the largest role in flattening the progressive income tax brackets. But notice all the other legislation that had positive net impact on receipts? This was due mostly to tax hikes and expansions of the taxable bases. Let’s take a closer look:
1. Tax Equity and Fiscal Responsibility Act of 1982 (TEFRA)
According to the U.S. Department of Treasury, this was the largest tax increase between 1968-2006.
*Increased airport and airway trust fund taxes
*Increased cigarette excise taxes
*Increased telephone excise taxes
*Increase of Federal unemployment taxes and taxable base
*Extension of social security hospital insurance taxes to Federal employees
*Instituted 10% withholding on dividends and interest paid to individuals
2. Highway Revenue Act of 1982
The highlight of this legislation is the tax on gasoline and diesel fuel went from 4 to 9 cents per gallon.
3. Social Security Amendments of 1983
* Accelerated scheduled increases in Social Security payroll tax rate
* Instituted taxation of some Social Security benefits
* Raised self-employed OASDHI rate to combined employee-employer rate, with SECA credit
* Extended mandatory Social Security coverage to non-profit and new federal employees
(Yup, that's right... Reagan expanded Social Security entitlements.)

4. Railroad Retirement Revenue Act of 1983
* Increased railroad retirement payroll taxes and railroad unemployment insurance taxes.
* Taxed railroad retirement pension plan benefits.
5. Deficit Reduction Act of 1984
*Increased distilled spirits excise tax
*Extended telephone excise tax.
*Restrictions on leasing. Reduced benefits from tax-exempt leasing and postponed effective data of liberalized finance leasing rules.
*Increased depreciable life of structures from 15 to 18 years.
6. Tax Reform Act of 1986
Most notably, this legislation consolidated the earned income tax structure. However, in doing so, Reagan proceeded to raise the taxes on the lowest income brackets while simultaneously decreasing the marginal rates of the top brackets quite substantially.

7. Consolidated Omnibus Budget Reconciliation Act of 1985
*Permanently extended 16 cents per pack cigarette excise tax.
*Enacted new excise tax on smokeless tobacco.
*Increased excise tax on coal production.
*Extended Medicare coverage to new state and local employees (This wasn't a tax hike, I just wanted to point out an expansion of entitlements.)
8. Superfund Amendments and Reauthorization Act of 1986
*Enacted excise tax of 8.2 cents per barrel on domestic crude oil and 11.7 cents per barrel on imported petroleum products.
*Enacted new broad-based tax on all corporations equal to 0.12 percent of alternative minimum taxable income in excess of $2 million.
*Enacted a 0.1 cent per gallon excise tax on gasoline, diesel fuels and other special motor fuels to finance cleanup of wastes from leaking underground petroleum storage tanks.
9. Continuing Resolution for 1987 (and 1988)
*Increased Internal Revenue Service funding for staffing and equipment.
Although, this isn’t necessarily a tax hike, it is still an interesting development in tax legislation that generated additional revenue.
“Increase in Internal Revenue Service (IRS) Funding – Funds were provided to the IRS for additional examiners; additional staff to handle appeals and litigation related to tax shelters; an automated examination system; and a system to match information documents supplied by third parties against taxpayer returns. These increases in staffing and equipment will help IRS ensure the smooth implementation of tax reform, improve tax law enforcement, and reduce the gap between taxes owed and taxes paid.”

10. Omnibus Budget Reconciliation Act of 1987
There is a lot of information in this one, but here are some highlights:
* Extended telephone excise tax
* Eliminated ESOP estate tax deduction loophole
*Occupational taxes imposed on the producers and manufacturers of alcohol, tobacco, and firearms products
*Increased taxes on the dealers of alcohol and firearms
Many other corporate tax loopholes and such were plugged up in this legislation. For more information check out:
Office of Management and Budget, Budget of the United States Government, Fiscal Year 1989 (Washington: U.S. Government Printing Office, 1987), p. 4-5.
11. Medicare Catastrophic Coverage Act of 1988
* Passed new supplemental premium tax on all persons eligible for Medicare. Premium rate was 15 percent of individual income tax liability in excess of $150, increased to 28 percent in 1993. Premium limited to $800 in 1989, raised to $1,050 in 1993, with future premium cap dependent on medical care costs after 1993.

Now don't get me wrong, I'm not demonizing Reagan for raising taxes. I'm simply pointing out that Reagan wasn't the patron saint of tax cuts that conservatives are led to believe (or claim). In fact, there was a time when Republicans actually did what was necessary to rein in the deficit. Although Reagan never technically balanced the budget, quite the opposite actually, he at least tried. These days the GOP and the teabaggers would have crucified him.
I’d also like to take a moment to discuss the Laffer Curve. This is an interesting model because it essentially illustrates a theoretical equilibrium of the tax rate that will generate the most revenue for the government. The premise of the model basically states that if the government taxes firms and labor 0%, the government will not collect any money. Conversely, if the government has a tax rate of 100%, they will not generate any revenue because there would be no incentive for productivity. Therefore, a happy medium needs to be reached somewhere in between that maximizes revenue and incentive to earn. Makes sense, right?

This is the model that Reagan used to justify lowering the tax rates to (unsuccessfully) appease budgetary critics. Essentially, this model suggests that at a certain point taxes are too high and need to be cut. The cuts will then create incentive to earn and ultimately more tax revenue will be collected because of increased productivity. In other words, tax cuts pay for themselves. However, the assumptions of this model have yet to prove themselves because tax cuts have never been empirically shown to increase revenue for the government. In fact, in 1989, the net effect of Reagan's tax cuts were -$568B (ERTA + Tax Reform Act of 1986). Obviously, something went horribly wrong somewhere in the logic. But in all fairness, the model doesn't actually provide equilibrium rates. It is left up for the politicians to decide.
I would also like to point out that by broadening the tax base, closing corporate loopholes, and taxing various areas in service, we could then lower everybody’s rates and spread the risk of massive revenue loss due to a recession and widespread unemployment.
This is what Reagan was trying to accomplish and I agree that the government is too heavily leveraged in personal income and payroll taxes. But these concepts are lost in the minds of pundits, politicians, and consequently the populace. I miss the days when the Chamber of Commerce ran the GOP. The GOP should be taking cues from Frum and not Fox.
In the end, I know that this information makes conservatives squirm. How could their beloved Reagan possibly raise taxes? Most will probably just ignore these data and continue living in bliss. Others will try to justify and rationalize it. Perhaps arguing that it was never really Reagan who raised the taxes and subsequently claim it was congress. Well, by that rational, Reagan never lowered the taxes to begin with and the whole basis that defines his presidency is inaccurate. The truth is, the president sets the tone for the country through actions and words. Not to mention, signs the legislation into law.
