Key Findings:

  • Senator Cruz’s (R-TX) taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. plan would enact a 10 percent flat taxAn income tax is referred to as a “flat tax” when all taxable income is subject to the same tax rate, regardless of income level or assets. on individual income and replace the corporate income taxA corporate income tax (CIT) is levied by federal and state governments on business profits. Many companies are not subject to the CIT because they are taxed as pass-through businesses, with income reportable under the individual income tax. and all payroll taxes with a 16 percent “Business Transfer Tax,” or subtraction method value-added tax. In addition, his plan would repeal a number of complex features of the current tax code.
  • Senator Cruz’s plan would cut taxes by $3.6 trillion over the next decade on a static basis. However, the plan would end up reducing tax revenues by $768 billion over the next decade when accounting for economic growth from increases in the supply of labor and capital and the much broader tax baseThe 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. due to the new value-added tax.
  • According to the Tax Foundation’s Taxes and Growth Model, the plan would significantly reduce marginal tax rates and the cost of capital, which would lead to a 13.9 percent higher GDP over the long term, provided that the tax cut could be appropriately financed.
  • The plan would also lead to a 43.9 percent larger capital stock, 12.2 percent higher wages, and 4.8 million more full-time equivalent jobs.
  • On a static basis, the plan would cut taxes by 9.2 percent, on average, for all taxpayers.
  • Accounting for economic growth, all taxpayers would see an increase in after-tax incomeAfter-tax income is the net amount of income available to invest, save, or consume after federal, state, and withholding taxes have been applied—your disposable income. Companies and, to a lesser extent, individuals, make economic decisions in light of how they can best maximize their earnings. of at least 14 percent at the end of the decade.

This week, Senator Ted Cruz (R-TX) released details of a tax reform plan.[1] This plan would institute a flat 10 percent tax rate on all varieties of individual income, with a large standard deductionThe standard deduction reduces a taxpayer’s taxable income by a set amount determined by the government. It was nearly doubled for all classes of filers by the 2017 Tax Cuts and Jobs Act (TCJA) as an incentive for taxpayers not to itemize deductions when filing their federal income taxes. and personal exemption. It would also repeal all itemized deductions except for the charitable deduction and the home mortgage interest deductionThe mortgage interest deduction is an itemized deduction for interest paid on home mortgages. It reduces households’ taxable incomes and, consequently, their total taxes paid. The Tax Cuts and Jobs Act (TCJA) reduced the amount of principal and limited the types of loans that qualify for the deduction. . The plan would replace the corporate income tax and all payroll taxes with a broad-based “Business Transfer Tax,” or value-added tax (VAT), with few exemptions. The plan would maintain the Child Tax CreditA tax credit is a provision that reduces a taxpayer’s final tax bill, dollar-for-dollar. A tax credit differs from deductions and exemptions, which reduce taxable income, rather than the taxpayer’s tax bill directly. and expand the Earned Income Tax Credit by 20 percent. In addition, the plan would eliminate the Estate TaxAn 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. , the Alternative Minimum Tax, the Net Investment Income Tax, and miscellaneous credits.

Our analysis finds that the plan would reduce federal revenues by $3.6 trillion over the next decade. However, the plan would improve incentives to work and invest, which would increase gross domestic product (GDP) by 13.9 percent over the long term. This increase in GDP would translate into 12.2 percent higher wages and 4.8 million new full-time equivalent jobs. After accounting for increased incomes due to these factors, the plan would reduce tax revenues by $768 billion.

Details of the Ted Cruz Tax Plan

Individual Income TaxAn 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. Changes

  • Consolidates the current seven tax brackets into one bracket at 10 percent on all personal income (wages, salaries, interest, capital gains, dividends, and business income).
  • Increases the Standard Deduction from $6,300 ($12,600 married filing jointly) to $10,000 ($20,000 married filing jointly) while retaining the personal exemption.
  • Eliminates all itemized deductions except for the home mortgage interest deduction and the charitable deduction. Places a tighter cap on the home mortgage interest deduction.
  • Eliminates the Alternative Minimum Tax.
  • Eliminates the Net Investment Income Tax of 3.8 percent and the Medicare surtaxA surtax is an additional tax levied on top of an already existing business or individual tax and can have a flat or progressive rate structure. Surtaxes are typically enacted to fund a specific program or initiative, whereas revenue from broader-based taxes, like the individual income tax, typically cover a multitude of programs and services. of 0.9 percent, which were passed as part of the Affordable Care Act.
  • Eliminates all individual tax credits except for the Child Tax Credit and the Earned Income Tax Credit. Expands the Earned Income Tax Credit by 20 percent.
  • Preserves the exclusions from income of pension contributions, employer-provided health premiums, and imputed rent, similar to current law.
  • Creates a new “universal savings account” that allows up to $25,000 of tax-deductible saving.
  • Eliminates the payroll taxA payroll tax is a tax paid on the wages and salaries of employees to finance social insurance programs like Social Security, Medicare, and unemployment insurance. Payroll taxes are social insurance taxes that comprise 24.8 percent of combined federal, state, and local government revenue, the second largest source of that combined tax revenue. .

Business Tax Changes

  • Eliminates the corporate income tax.
  • Provides a temporary tax holiday at a 10 percent rate (instead of a full 35 percent rate) on any deferred foreign profits that are repatriated.

Other Changes

  • Enacts a broad-based, 16 percent “Business Transfer Tax” or value-added tax. This tax is levied on all business profits, less capital investment. This would include the payroll of business, government, and non-profit institutions, as well as net imports. The tax would exempt from taxation the purchase of health insurance. A business transfer tax is also often known as a subtraction-method value-added tax. While its base is identical in economic terms to that of the credit-invoice VAT seen in many OECD countries, it is calculated from corporate accounts, not on individual transactions. [2]
  • Eliminates the estate tax.

Economic Impact

Senator Cruz’s tax reform would be a significant shift from the current tax code. Under this plan, the income tax would be greatly diminished in its importance compared to current law. Instead, the U.S. federal government would raise 71 percent of all revenue from the new broad-based value-added tax. The tax is a broad consumption taxA consumption tax is typically levied on the purchase of goods or services and is paid directly or indirectly by the consumer in the form of retail sales taxes, excise taxes, tariffs, value-added taxes (VAT), or an income tax where all savings is tax-deductible. that would include most of U.S. GDP, including both wages and profits.[3] Due to these changes, the taxation of investment would significantly decline, which would greatly increase incentives to save and invest.

According to our Taxes and Growth Model, the increased incentives to work and invest from this tax plan would increase the size of the economy by 13.9 percent over the long run. The plan would lead to 12.2 percent higher wages and a 43.9 percent larger capital stock. The larger economy would mainly result from a significant reduction in the service price of capital, due to the elimination of the corporate income tax and the significant reduction in the individual income tax. In addition, the reduction of marginal tax rateThe marginal tax rate is the amount of additional tax paid for every additional dollar earned as income. The average tax rate is the total tax paid divided by total income earned. A 10 percent marginal tax rate means that 10 cents of every next dollar earned would be taken as tax. s on individual income would increase incentives to work and result in 4.8 million full-time equivalent jobs.

Revenue Impact

The Senator’s plan would eliminate the corporate income tax, the payroll tax, and the estate tax, which combined would reduce federal revenue by $17.3 trillion over the next decade. The reduction in individual income tax rates would lower revenue by an additional $11.8 trillion. Most of this revenue would be made up for with revenue from the new 16 percent value-added tax. This tax would raise $25.4 trillion over the next decade. On net, the plan would reduce federal revenue on a static basis by $3.6 trillion over the next ten years.If we account for the economic growth that the plan would produce, the plan would end up lowering revenue by $768 billion over the next decade. The larger economy would increase wages, which would narrow the revenue lost through the individual income tax by about $700 billion. In addition, the new value-added tax would end up raising $2.2 trillion more over the next decade, due to growth of the economy.

Distributional Impact

On a static basis, Senator Cruz’s tax plan would increase after-tax incomes by 9.2 percent, on average. Taxpayers in all income groups would see higher after-tax incomes.

Taxpayers in the bottom decile would see a 4.3 percent increase in after-tax income due to the expansion of the Earned Income Tax Credit, which more than offsets the impact of the new value-added tax. The next six deciles (the 10th through 70th percentiles) would see increases in after-tax adjusted gross incomeFor individuals, gross income is the total pre-tax earnings from wages, tips, investments, interest, and other forms of income and is also referred to as “gross pay.” For businesses, gross income is total revenue minus cost of goods sold and is also known as “gross profit” or “gross margin.” (AGI) of between 1.2 and 2.4 percent. High income taxpayers that fall in the highest income class (the 90-100 percent decile) would see an increase in after-tax income of 17.4 percent. The top 1 percent of all taxpayers would see a 29.6 percent increase in after-tax income.

On a dynamic basis, the plan would increase after-tax incomes by 21.3 percent on average. All deciles would see an increase in after-tax AGI of at least 14.2 percent over the long term. Taxpayers that fall in the bottom decile would see their after-tax AGIs increase by 15.3 percent. The middle eight deciles would see increases in their after-tax AGI between 14.2 and 18.4 percent. The top decile would see an increase in after-tax AGI of 27.1 percent, and the top 1 percent of all taxpayers would see an increase in after-tax AGI of 34.2 percent.

Senator Cruz’s tax plan would significantly alter the federal tax code. It would completely repeal the corporate income tax and all payroll taxes and enact a 10 percent income tax and a 16 percent “business transfer tax” or value-added tax. These changes to the tax code would increase the incentives to work and invest and would greatly increase the U.S. economy’s size in the long run, leading to higher incomes for taxpayers at all income levels. The plan would also be a large tax cut, which would increase the federal government’s deficit by over $3.6 trillion on a static basis. Accounting for the growth caused by the plan, federal revenues would decline by $768 billion over the next decade.

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 effects of any spending cuts that may be required to finance the plan.

We modeled most of the major provisions outlined above, except for a few that are beyond the scope of the model, or require data that is not available. We did not model the economic impacts nor the costs of the proposed universal saving accounts. We did not model the repatriationTax repatriation is the process by which multinational companies bring overseas earnings back to the home country. Prior to the 2017 Tax Cuts and Jobs Act (TCJA), the U.S. tax code created major disincentives for U.S. companies to repatriate their earnings. Changes from the TCJA eliminate these disincentives. tax holiday. We assumed that the EITC expansion was applicable to all currently eligible taxpayers. As such, their EITC payments increased by 20 percent. In modeling the value-added tax, we held prices constant and passed the tax back to the factors of production.

Under current law, some taxes on labor are explicitly levied on nominal wages, reducing take-home pay, while others are implicitly passed on to workers through lower nominal wages. The business transfer tax would also fall substantially on payrolls, but it would do so entirely through implicit reductions in nominal wages rather than explicit reductions in take-home pay. The change in wage rate reported here is the net of growth in labor productivity as well as the explicit and implicit changes in worker take-home pay due to taxes.

[2] This rate is in tax-inclusive terms. This is equivalent to a credit-invoice value-added tax or sales taxA sales tax is levied on retail sales of goods and services and, ideally, should apply to all final consumption with few exemptions. Many governments exempt goods like groceries; base broadening, such as including groceries, could keep rates lower. A sales tax should exempt business-to-business transactions which, when taxed, cause tax pyramiding. of approximately 19 percent on goods and services.

[3] This makes it similar to the combination of a payroll tax and a corporate income tax with immediate cost recoveryCost recovery is the ability of businesses to recover (deduct) the costs of their investments. It plays an important role in defining a business’ tax base and can impact investment decisions. When businesses cannot fully deduct capital expenditures, they spend less on capital, which reduces worker’s productivity and wages. . Both the payroll tax and the corporate income tax under current law would be eliminated under the proposal.
