What To Expect With Tax Reform

This Strategic Insights discusses how to bolster tax revenue by increasing potential growth, job opportunity, and productivity. This may be achieved by lowering tax rates, reforming regulation, simplifying the tax code, and incentivizing investment to enhance global competitiveness. Various guiding principles outlined herein suggest how to tackle the broader issue of fiscal reform, including spending and tax reform.

Today’s fiscal deficit remains high and unsustainable by global historical standards with rapidly expanding entitlement programs in excess of inflation. U.S. Debt/GDP exceeds 80% with a current 3% fiscal deficit---spending exceeds tax revenue by 3% of GDP. Treasury debt has doubled to $20 trillion since 2009. Only by extinguishing the fiscal deficit can we begin to bend the curve below.

Tax reform is one side of needed fiscal reform—spending also must be addressed to turn a high fiscal deficit into surplus during periods of economic growth. Raising tax rates historically slowed real growth in GDP and tax revenue as inflation increased. Growth has disappointed since 2009 due to higher tax rates1, spending, fiscal stimulus, and new regulations2, which limited growth and therefore tax revenue. Debt/GDP should be falling now, if not for misguided fiscal and regulatory policies. Pro-growth tax and regulatory reform can do the heavy lifting of fiscal reform with additional discipline of spending reform.

Drivers of spending growth are obvious in the chart below, including Social Security, retirement liabilities, health care, and interest. Mandatory outlays plus interest totalling $2.8 trillion in 2017 are 70% of the budget. Staring at this chart, we realize growth in mandatory spending programs must slow. Spending reform is politically difficult, but must be coupled with tax reform to extinguish our unsustainable fiscal deficit.
