Biden's Tax Plan Takes The Wrong Approach On Social Security
Most major polls show that Joe Biden has pulled ahead of Donald Trump in the race for the White House. As such, it’s prudent to start considering what his policies may mean for the economy and financial markets, starting with his tax plan. When you get into the details, you realize that although Biden is widely regarded as a centrist Democrat, his proposed plan is anything but.
For starters, Biden credibly threatens to take a tax code that is already steeply progressive and make it even more progressive, with nearly all of the increased tax burden falling on the top 2% of taxpayers. That’s a problem for a couple of big reasons. For one, it would clearly discourage savings, investment, and business formation, potentially causing lasting economic damage. Plus, it wouldn’t do much to reduce income and wealth inequality.
At the center of Biden’s plan is the taxes on earnings used to fund Social Security. Currently, payroll taxes are only levied on the first $137,700 in income, subject to an annual cost of living increase. The employee and employer each pay 6.2% in Social Security tax; self-employed individuals pay both sides, or 12.4%. Biden proposed applying this tax to an unlimited amount of income above $400,000, leaving a “donut hole” between $137,700 and $400,000, which he expects will gradually narrow over time with inflation. Also, Biden wants to re-raise the top marginal tax rate from 37% to 39.6%.
In effect, the Social Security tax would cease being a payroll tax and would effectively serve as a new, higher marginal rate. Critics of payroll taxes have said the payroll tax is a regressive tax, but it’s intended to be that way. The original purpose of the tax was to ostensibly to fund each individual’s Social Security benefits, not fund general government revenues. Making the Social Security tax progressive, thereby increasing marginal rates into the 50% range for self-employed people, who would pay both sides of the tax, would be a huge disincentive to entrepreneurship.
