That may sound nutty and even disloyal coming from a Californian. Millions of state residents, after all, would be hammered by elimination of the state and local tax deductions.
But let's be intellectually honest. There's no credible justification for the federal government subsidizing California's highest-in-the-nation state income tax — or, for that matter, any local levy like the property tax.
Why should federal tax money from people in other states be spent on partially rebating Californians for their state and local tax payments? Some of those states don't even have their own income tax, including Nevada and Washington. Neither do Texas and Florida.
The federal subsidies just encourage the high-tax states to rake in more money and spend it. And they numb the states' taxpayers.
Former California Gov.
"I don't believe that we can justify a system that forces taxpayers in low-tax states to subsidize the big-spending policies of a few high-tax states," Reagan said.
But Reagan managed to only scrub the sales tax deduction. That was in 1986, the last time the federal tax code was significantly retooled.
States with no income taxes to deduct howled. So after Texan George W. Bush was elected president, taxpayers were given an option to deduct either the state income or sales tax.
Trump's framework for a federal tax overhaul, among other things, would eliminate the deductions for all state and local taxes.
Republican state Sen. Jeff Stone of Temecula put it this way after Trump unveiled his proposal last week: “For years, the
Trump's plan, Stone continued, "seems to finally force states to be transparent about how much they actually tax their own residents."
One correction: Blame it on California voters. True, the last two "soak the rich" tax measures in California were sponsored by Democrats and labor unions. But they were approved by state voters.
Trump called his plan "a once-in-a-generation opportunity" for "historic tax relief."
State Sen. Bob Hertzberg (D-Van Nuys) labeled it "a big wet kiss" for California tax reform, for which he long has advocated.
Well, it's not exactly relief or a kiss for the roughly 6 million Californians who deduct state and local taxes when they itemize on their federal 1040s. They'd suffer pocketbook pain.
The deductions totaled $101 billion for Californians in 2014, the last year for which there are data, according to the nonpartisan Tax Foundation. But the deductions have risen since then.
Gov. Jerry Brown's budgeters are anticipating nearly $91 billion in state income tax revenue alone during the current fiscal year. Under Trump's proposal, that couldn't be deducted on federal tax returns.
Some of that loss would be offset by Trump's lowering of the income tax rates. But those and other details of the plan haven't been written, so it's impossible to project the bottom line.
Let's assume, however, that the century-old deduction for the state income tax is finally eliminated. That would hit upper middle class and wealthy Californians especially hard because the top state rate here climbs to 13.3%.
Wouldn't it finally be time to lower income tax rates and extend the sales tax to some services? That should have been done long ago to stabilize the state tax system and bring it into the 21st century.
Our archaic system is way too volatile. The nonpartisan Legislative Analyst's Office reported last week that income tax revenue is five times as volatile as personal income itself.
The "unpredictable revenue swings complicate budgetary planning and contributed to the state's boom-and-bust budgeting of the 2000s," the analyst wrote.
During the recession in 2008, for example, a 3.7% dip in the California economy resulted in a 23% nosedive in state revenue.
The revenue stream has become unreliable because it depends too heavily on high-income earners, especially their capital gains. During an economic downturn, capital gains go bust and revenue slows to a trickle.
In 2015, the top 1% of California earners paid about 48% of the total state income tax while drawing 24% of the taxable income.
California has shifted from a predominately manufacturing to a service economy over the decades. We tax retail sales, but still not services. And the sales tax has tailed off. In 1950, it supplied 60% of state general fund revenue. Today, it's less than 20%. The income tax in 1950 filled just 10% of the general fund. Today it's 70%.
So we should lower both the income and sales tax rates and start taxing some services. Such services as auto repairs, legal advice, architecture and Dodgers tickets. And political consulting.
There'd certainly be loud wailing from special interests. And legislators mostly are cowards.
But Hertzberg thinks Trump has provided some cover for lawmakers to finally act. If the president's plan passes, he says, "people won't be able to still say: 'These taxes aren't so bad. They're deductible.' Now the politics changes."
Hertzberg adds: "We've got to solve this volatility problem. How many years have we talked about this?"
Trump's plan may be the best thing that ever happened for California's rickety tax system.
