In the last weeks of the campaign, Donald Trump is slicing and dicing the Federal income tax nearly as fast as he served up fries at the McDonald’s drive-thru window last weekend. So far, he has proposed to extend the lower rates, family tax credits, and investment incentives of the 2017 Tax Act after they expire in 2025 and to also exempt tips, Social Security benefits, and overtime wages from the Federal income tax. 

Those items alone would generate a revenue loss of $9 trillion over the next decade, but he has recently proposed to also exempt firefighters, police officers, military personnel, and veterans from the Federal income tax as well.

We estimate the latter would cost another $2.5 trillion in revenue loss over 10 years. As it happens, there are 370,000 firemen, 708,000 policemen, 2.86 million uniformed military personnel, and 18.0 million veterans in the US. These 22 million citizens have an estimated average income of $82,000 per year, which translates to about $60,000 each of AGI (adjusted gross income). At an average income tax rate of 14.7% these exclusions would generate $250 billion per year of reduced income tax payments.

In all, Trump has thus tossed out promises to cut income taxes by $11.5 trillion over the next 10-year budget window. In turn, these sweeping reductions would amount to upwards of 34% of CBO’s estimated baseline income tax revenue of $33.7 trillion over the period. Alas, even in the halcyon days of Reagan supply-side tax cutting no one really dreamed of eliminating fully one-third of the so-called crime of 1913 (the 16th Amendment which enabled the income tax).

10-Year Revenue Loss:

Extend the 2017 Trump tax cuts: $5.350 trillion.

Exempt overtime income: $2.000 trillion.

End Taxation of Social Security benefits: $1.300 trillion.

Exempt Tip income: $300 billion.

Exempt Income of Firemen, Policemen, Military and Veterans: $2.500 trillion.

Trump Total Revenue Loss: $11.500 trillion. 

CBO Income Tax Baseline Revenue: $33.700 trillion.

Trump Revenue Loss As % of Baseline: 34%.

Then again, Trump may have something virtually epic in mind. To wit, scrapping the income tax entirely in favor of taxing consumption via levies on imported goods and merchandise.

“In the old days when we were smart, when we were a smart country, in the 1890s and all, this is when the country was relatively the richest it ever was. It had all tariffs. It didn’t have an income tax,” Trump said at a sit-down with voters in New York on Friday for Fox & Friends. 

“Now we have income taxes, and we have people that are dying.”

The New York Times is deeply alarmed:

“The former president has repeatedly praised a period in American history when there was no income tax, and the country relied on tariffs to fund the government.” 

Actually, however, 19th-century America was even smarter than Trump realizes.

In 1900 total Federal spending amounted to just 3.5% of GDP because back then America was still a peaceful republic and had no Warfare State or even significant standing army at all. And save for the most advanced precincts of Europe, the Welfare State hadn’t yet been invented, either.

So, yes, the so-called “revenue tariffs” of the 19th century did meet the income needs of the Federal government to the point of actually balancing the budget year after year between 1870 and 1900. Indeed, the actual annual surpluses were large enough to pay down most of the Civil War debt, to boot.

Today, of course, the Warfare State, Welfare State, and the Washington pork barrels account for 25% of GDP. So Trump may be directionally correct in wanting to tax consumption rather than income, but, as usual, he’s off by about seven orders of magnitude when it comes to the size of the Federal budget that needs to be financed.

Still, Trump has stepped up to the plate when it comes to a 21st-century version of the revenue tariff. He has pledged to impose a 20% universal tariff on all imports from all countries with a specific 60% rate for Chinese imports. Based on current US import levels of $3.5 trillion per year from worldwide sources and $450 billion from China, Trump’s tariffs would generate about $900 billion of receipts per annum.

To be sure, Trump’s claim that these giant tariffs would be paid for by Chinamen, Mexicans, and European socialists is just more of his standard baloney. Tariffs are paid for by consumers, but that’s actually the hidden virtue of the Tariff Man’s favorite word.

The truth is, government should be paid for via taxation on current citizens, not fobbed off in the form of giant debts on future citizens, born and unborn. So if we are going to have Big Government at 25% of GDP rather than a 19th-century government at 3.5% of GDP, and Trump is a Big Government Man if there ever was one, better that the burden be placed on consumption, not production, income, and investment.

After all, today the “makers” get hit good and hard by the current exceedingly lopsided income tax system. Thus, the top 1% pays 46% of income taxes, while the top 5% pays 66% and the top 10% pays 76% of all income taxes. On the other end, by contrast, the bottom 50% pays just 2.3% of individual income taxes, while 40% of all families pay no income tax at all.

In any event, the math works out such that the proposed Trumpian revenue tariffs would generate about $9 trillion over the next decade, or nearly 80% of the $11.5 trillion revenue loss from drastically shrinking the income tax coverage and collection rate. So that’s a big step in the direction of fiscal solvency rather than more UniParty free lunches.

To be sure, the proper redirection of Federal tax policy would be a national sales tax or VAT levy, which could be applied to both goods and services and to domestically produced output as well as to imports. Thus, a 5% VAT on the current $20 trillion per year of total PCE (personal consumption expenditures) would generate the equivalent of Trump’s revenue tariff, while a 15% levy on total PCE could replace both the Trump tariff and the remainder of the income tax entirely.

Notwithstanding its shortcomings, however, a revenue tariff is a long overdue start in the right direction. Trump’s bold stance in favor of taxing consumption rather than income and requiring all households to bear the cost of government, not just the small number of producers at the top of the economic ladder, is clearly superior to the status quo.

Still, this sweeping change in the composition and incidence of tax policy doesn’t really put the impending fiscal disaster to bed. Not by a long shot.

If you assume Trump’s big revenue tariffs and sweeping income tax cuts and that the other Federal payroll, corporate, and excise taxes remain the same, 10-year revenues compute to just $60 trillion versus built-in spending of $85 trillion per the CBO baseline. In short, even with a giant Trumpified version of the historical revenue tariff, Trump’s budget plan would still generate $25 trillion of red ink over the next decade.

10-Year Budget Outlook with Trump Tax Cuts and Tariffs, 2025 to 2034:

Individual income taxes with Trump cuts: $22.0 trillion.

Trump Revenue Tariffs: $9.0 trillion.

Existing Payroll Taxes: $20.9 trillion.

Existing Corporate Tax Ex-Trump Cut to 15% on Manufacturers: $4.6 trillion.

Other Existing Federal Receipts: $3.5 trillion.

Total Federal Revenue Under Trump Policy: $60.0 trillion.

CBO Baseline Federal Outlays: $85.0 trillion.

10-Year Trump Deficit: $25.0 trillion.

To be sure, Trump has promised to turn Elon Musk loose on a crusade against government waste and inefficiency, and we say more power to him. If anyone has the courage and smarts to take on the Swamp, surely Elon Musk is at the top of the list.

Then again, Trump has promised to shield 82% of the budget from any cuts at all. That’s right. Elon could huff and puff and shrink the non-exempt programs and agencies by one-third and still leave deficits in excess of $20 trillion over the next decade.

10-year Cost Of Programs Trump Has Championed, Promised Not To Cut or Can’t Cut:

Social Security: $20.0 trillion.

Medicare: $16.0 trillion.

Federal Military and Civilian Retirement Pensions: $2.5 trillion.

Veterans’ programs: $3.0 trillion.

National Security Budget: $15.5 trillion.

Interest On the Public Debt: $13.0 trillion.

Total Exempt Programs: $70.0 trillion. 

Exempt Programs As % of $85 trillion CBO Baseline: 82%.

In short, even with Trump’s full revenue tariffs and assuming Elon could actually slash 33% of the non-exempt budget without closing the Washington Monument, the bottom-line math leaves little to the imagination. Spending at $80 trillion would amount to 22.7% of GDP, while Trump’s tariff-heavy revenue package would generate $60 trillion of Federal receipts over the next decade, amounting to about 17.0% of GDP.

In turn, that would leave a structural deficit of nearly 6% of GDP as far as the eye can see. And that projection assumes no recession ever again and that interest on a public debt approaching $60 trillion by 2034 would average just 3.3% across the maturity spectrum.

We will take the unders on that proposition any day of the week and twice on Sunday. That is to say, CBO’s projection of $1.7 trillion of annual interest expense by 2034 is likely understated by several trillion. Per year.

In any event, the challenge of financing these giant deficits along with $900 billion per year of Trump tariffs would be considerable. The latter alone would amount to nearly 10% of annual US consumption of consumer goods and fixed investment goods.

So if the Fed were to “accommodate” these massive Trump tariffs by running the printing presses red-hot in an attempt to compensate for lost household purchasing power, it could well trigger a burst of inflation even more virulent than that of 2021-2024. 

On the other hand, were it to adhere to the correct sound money solution and refuse to “accommodate” both the massive Trump deficits and the giant Trump tariffs, bond yields, and interest rates would soar, even as the Main Street economy contracted sharply in response to a one-time 10% increase in the general price level.

Financing massive budget deficits honestly in the bond pits rather than at the Fed’s printing presses would also unleash the mother of all meltdowns in today’s insanely inflated financial markets. Trump would therefore get his tariff and some substantial reshoring of industrial production, but also a hair-curling recession on Main Street and a Bronx Cheer from the canyons of Wall Street. 

Unfortunately, that’s the price America would have to pay even under Trumpian economics to purge the destructive effects of decades of UniParty spend, borrow, and print policies.

Still, we can actually think of a decidedly worse scenario. To wit, perpetuation of the UniParty status quo, which is what we would get from the Washington ruling party that replaced a failing mind in the Oval Office with an empty one on the Democratic presidential ticket.
