SALT in the Gears of the Big, Beautiful Tax Cut?

Congress and President Trump are working to pass the “One Big Beautiful Bill” legislation that makes the Trump tax cuts permanent, cuts spending by $1.7 trillion, secures the border and strengthens the U.S. military.
But. Always a “but.”
Some congressmen have been threatening to vote against the bill if it fails to raise the cap on SALT significantly. No, it’s not the alternative to pepper. SALT is the acronym for State and Local Taxes.
Today, you can deduct $10,000 of your state and local tax payments from your income before you calculate your federal income taxes. The vast majority of taxpayers (91 percent) claim no SALT deduction at all, while taxpayers with incomes of $200,000 or more receive 65 percent of the SALT deduction’s tax benefits.
Who is affected by the limit on the deductibility of State and Local Taxes? Those with very high incomes who live in states with very high income taxes and very high property taxes. Think New York City, San Francisco and Los Angeles.
Thinking politically: Blue cities in Blue states. Cities with mayors who refuse to control city spending. Governors who refuse to control state spending. They like the federal subsidy for their higher taxes.
Some congressmen think we should change federal law to make it easier for politicians at the state and local levels to increase taxes. Then the local pols could say — “Hey, why complain about my property hikes and income tax increases. Those are deductible against federal taxes. If I, your mayor, didn’t take your money, the feds would tax what I don’t take.”
Think of the deductibility of SALT as a subsidy for big government at the state and local levels. It helps mayors and governors sell higher state and local taxes.
Not all states care.
Eight states do not have to worry about whether or not their state income tax payments are deductible when calculating federal taxes. Those states have zero state income tax. You read about them in the annual reports, where you learn that many Americans move to states with no income taxes: Texas, Florida, Tennessee, Nevada, New Hampshire, South Dakota, Wyoming and Alaska.
In addition, there are 10 states where the governor and state legislature have initiated the process of phasing their state income tax to zero: Arizona, Iowa, Indiana, Oklahoma, North Carolina, South Carolina, Mississippi, Louisiana, Utah and Arkansas.
Several states limit the power of local governments to raise property taxes through state laws and constitutional amendments.
The deductibility of SALT requires Americans in all states to pay the taxes of higher-income Americans in blue cities in blue states.
If all state and local taxes were deductible, it would shift $1.2 trillion in taxes onto the rest of us. That is a significant subsidy to keep Democratic mayors and governors from having to govern effectively.
How could this problem of high taxes be fixed at the city and state levels?
Citizens who live in blue cities can vote for mayors who limit spending and taxes. Citizens in blue states can elect governors and state legislators who have some self-control over other people’s money.
Equally important to limiting the importance of SALT/NO SALT is reducing tax rates for federal taxpayers. And the senators from New York and California who complain about losing SALT deductions are the same politicians who imposed high tax rates on all federal taxpayers in California and New York and other blue high-tax states.
The Trump tax cut will become permanent law. Tax rates will not be increased. Expensing of business investment will create jobs and opportunities. And if the economy grows at 3 percent yearly instead of 1.5 percent, as predicted by White House economist Kevin Hassett, revenue would increase by $4 trillion over a decade.
It may be necessary to raise the SALT cap to get the Big Beautiful Bill across the finish line. However, the more Congress increases the SALT cap, the more it allows progressive politicians to get away with high taxes and high spending.
