Details and Analysis of Senator Bernie Sanders’s Tax Plan

Over the past few months, Senator Bernie Sanders (I-VT) has released details of changes he would make to the federal tax code.[1] His plan would increase marginal tax rates on all taxpayers, through higher individual income tax An individual income tax (or personal income tax) is levied on the wages, salaries, investments, or other forms of income an individual or household earns. The U.S. imposes a progressive income tax where rates increase with income. The Federal Income Tax was established in 1913 with the ratification of the 16th Amendment. Though barely 100 years old, individual income taxes are the largest source of tax revenue in the U.S. rates and two new payroll taxes. The plan includes several provisions aimed at high-income households: it would raise the top marginal income tax rate to 54.2 percent, tax capital gains and dividends as ordinary income, replace the alternative minimum tax with a new limit on itemized deductions, and expand the estate tax An estate tax is imposed on the net value of an individual’s taxable estate, after any exclusions or credits, at the time of death. The tax is paid by the estate itself before assets are distributed to heirs. . In addition, the plan would create a new financial transactions tax and move the U.S. toward a worldwide tax system by ending the deferral of foreign-source business income.

Our analysis finds that the plan would increase federal revenues by $13.6 trillion over the next decade. The plan would also increase marginal tax rates on both labor and capital. As a result, the plan would reduce the size of gross domestic product (GDP) by 9.5 percent over the long term. This decrease in GDP would translate into an 18.6 percent smaller capital stock and 6.0 million fewer full-time equivalent jobs. After accounting for the economic effects of the tax changes, the plan would end up increasing federal tax revenues by $9.8 trillion over the next decade.

Economic Impact

According to the Tax Foundation’s Taxes and Growth Model, Senator Bernie Sanders’s tax plan would reduce the economy’s size by 9.5 percent in the long run. The plan would lead to 4.3 percent lower wages, an 18.6 percent smaller capital stock, and 6.0 million fewer full-time equivalent jobs. The smaller economy results from higher marginal tax rates on capital and labor income.

GDP -9.5%
Capital Investment -18.6%
Wage Rate -4.3%
Full-time Equivalent Jobs (in thousands) -5,973

Revenue Impact

Overall, the plan would increase federal revenue on a static basis by $13.6 trillion over the next 10 years. Most of the revenue gain is due to increased payroll tax revenue, which we project to raise approximately $8.3 trillion over the next decade. The changes to the individual income tax will raise an additional $4.9 trillion over the next decade. The remaining $350 billion would be raised through increased estate taxes and taxes on corporations.

If we account for the economic impact of the plan, it would end up raising $9.8 trillion over the next decade. The smaller economy would reduce wages and investment income, which would narrow the revenue gain from the income tax changes to $2.8 trillion and the revenue gain from the payroll tax changes to $7.0 trillion.

Estate and Gift Taxes $288 $243
Other Revenue $0 -$76
Total $13,574 $9,827

The largest sources of revenue in the plan are the new “health care premiums”: a 6.2 percent employer-side payroll tax and a 2.2 percent increase in the individual income tax. Together, these provisions would raise $6.6 trillion over 10 years, or $5.2 trillion after accounting for economic effects.

Another significant source of revenue for the Sanders plan has to do with the tax treatment of health insurance. Currently, households are not required to pay taxes on the value of health insurance they receive from their employers, which leads to over $300 billion a year in reduced federal revenue.[2] However, the Sanders plan would put an end to nearly all privately-provided insurance. As a result, employers would cease to compensate their employees with health insurance and would instead increase their wages and salaries by the value of the health insurance plans they used to provide.[3] These higher wages and salaries would then be subject to income and payroll taxes, causing federal tax revenues to increase by $3.6 trillion over the next decade, or $3.3 trillion after accounting for economic effects.

The components of the plan aimed specifically at increasing taxes on high-income households (partially removing the Social Security payroll tax cap, adding four new income tax brackets, and taxing capital gains and dividends at ordinary income rates) would increase federal revenue by $2.9 trillion on a static basis and $1.4 trillion after accounting for economic effects.

Distributional Impact

On a static basis, the Sanders tax plan would reduce the after-tax incomes of taxpayers in every income group. The bottom 50 percent of taxpayers would see their after-tax incomes decrease by at least 4.87 percent. The top 50 percent of taxpayers would see their after-tax incomes decrease by at least 8.57 percent. Finally, the top 1 percent of taxpayers would see their after-tax incomes fall by 17.91 percent.

After accounting for economic effects, taxpayers in all income groups would see their after-tax incomes decrease by at least 12.84 percent. The top 1 percent of taxpayers would see their incomes decrease by 24.88 percent.

It is important to note that these figures only reflect changes in after-tax income that result from Senator Sanders’s tax plan. They do not take into account the distributional effects of any of the spending programs that Senator Sanders has proposed.

Conclusion

Senator Bernie Sanders would enact a number of tax policies that would raise tax revenue over the next decade. Together, his proposals would significantly expand federal revenue collections by $13.6 trillion on a static basis, driven mostly by broad-based taxes on income and payroll. If enacted, the Sanders plan would significantly increase marginal tax rates on capital and labor income, which would result in a substantial reduction of the size of the U.S. economy in the long run. This would decrease the revenue that the new tax policies would ultimately collect to $9.8 trillion. Senator Sanders’s plan would decrease after-tax incomes for taxpayers at all income levels, but especially high-income taxpayers.

Modeling Notes

The Taxes and Growth Model does not take into account the fiscal or economic effects of interest on debt. It also does not require budgets to balance over the long term, nor does it account for the potential macroeconomic or distributional effects of any changes to government spending that may accompany the tax plan.

We modeled the revenue and economic impacts of the tax provisions outlined above except for changes to international tax rules, changes to estate tax rules (other than the rates and exclusion), limitations on like-kind exchanges, and the new financial transactions tax. The omissions were due to either data limitations or insufficient details from the candidate.[4] We do not model any potential transitional costs associated with the plan.

The tax plan released by the Sanders campaign was unclear on a few points. To seek additional clarity from the campaign, we sent the following document on January 19 th to the campaign policy staff, with questions about the details of the plan. The letter also explained what modeling assumptions we would use if the campaign did not send us further clarification. We did not receive a response, and therefore, we used the assumptions outlined in the letter below.

Clarifying Questions Regarding Senator Sanders’s Tax Plan

We are in the process of modeling the budgetary and economic effects of Senator Bernie Sanders’s tax plan. Below are a few questions, to clarify the details of the plan.

  1. The plan includes a “6.2% income-based health care premium paid by employers.”
    1. a. Would this premium apply to an employee’s payroll or an employee’s income?
    2. b. If the premium applies to an employee’s payroll, would there be any cap on the portion of payroll that is subject to the premium?
    3. c. If the premium applies to an employee’s income, what measure of income is subject to the premium? For instance, would the premium apply based on an employee’s AGI, MAGI, taxable income Taxable income is the amount of income subject to tax, after deductions and exemptions. For both individuals and corporations, taxable income differs from—and is less than—gross income. , or some other measure?
    4. d. If the premium applies to an employee’s income, what mechanism would businesses use to determine the income of their employees?
    5. e. If the premium applies to an employee’s income, would there be any cap on the portion of income that is subject to the premium?
    1. a. What measure of income is subject to the premium? Would the premium apply based on a household’s AGI, MAGI, taxable income, ordinary income, or some other measure?
    2. b. According to the most recent document released by the Sanders campaign, the marginal income tax rates for high income individuals would be 37%, 43%, 48%, and 52%. Do these rates include the 2.2% household premium? Or would the 2.2% premium apply on top of these rates?

    If we do not receive a response from the campaign by the end of January 25 th , we will make the following assumptions:

    1. We will assume that the “6.2% income-based health care premium paid by employers” is a payroll tax, rather than a tax on an employee’s overall income. We will assume that the tax applies to all payroll.
    2. We will assume that the “2.2 percent income-based premium paid by households” applies to taxable income. We will also assume that it applies in addition to the 37%, 43%, 48%, and 52% brackets, meaning that individuals earning over $10 million would pay a marginal income tax rate of 54.2%.
    3. We will assume that the net investment income tax rate is lowered to 0%, following the most recent statement of the Sanders campaign that capital gains and dividends would be taxed “the same as income from work.”
    4. We will assume that the Sanders plan does not include publicly-provided health insurance in taxable income.

    [2] Greenberg, Scott. “Options for Broadening the U.S. Tax Base The tax base is the total amount of income, property, assets, consumption, transactions, or other economic activity subject to taxation by a tax authority. A narrow tax base is non-neutral and inefficient. A broad tax base reduces tax administration costs and allows more revenue to be raised at lower rates. .” Tax Foundation. November 24, 2015. https://taxfoundation.org/article/options-broadening-us-tax-base.

    [3] Even in the event that some private employer-provided health plans remain, the Sanders plan eliminates health tax expenditures, which would mean that employer health premiums would still count as individual income.
