As the US economy continues to reopen, economic growth is accelerating in line with our above-consensus forecasts. This rebound has caused some investors to start dimensioning possible downside risks to the outlook. One area drawing more attention lately is looming change to corporate tax policy.
The Biden administration’s proposed infrastructure improvement plan, The American Jobs Plan, calls for rolling back some parts of the 2017 corporate tax rate cuts passed as part of the Tax Cuts and Jobs Act, along with enacting other measures to revise the corporate tax regime.
The initial proposal would raise the corporate tax rate from 21% to 28%. Of course, that’s subject to Congressional negotiation, which seems all but certain to produce a rate that remains well below the 35% rate in effect before the 2017 cuts. Some investors are worried that higher corporate tax rates would ultimately be a drag on economic growth.
We think it’s more likely that the tax hike will impact financial markets rather than the real economy.
2017 Tax Cuts Produced No Upswing in Business Investment
One sensible way to gauge the potential impact of a corporate tax hike is to take a look back at the impact of the 2017 tax cut, which dropped the rate from 35% to 21%.
The key variable is business investment: in theory, that tax-rate reduction should have boosted business investment, in turn putting extra muscle behind the US economy. If that theory proved true, it would stand to reason that raising the corporate tax rate should curtail business investment and slow growth.
However, the data seem to indicate that the 2017 corporate tax cut didn’t boost business investment much. Investment did expand in the ensuing quarters, but only gradually—and largely in line with its pre-tax-cut trajectory. Because there was no visible upswing in the trend, we expect that a partial unwinding of the 2017 tax cut won’t substantially slow business investment.
Indeed, given our expectation of surging demand and robust growth, we expect business investment to increase even if tax hikes go through. Investment decisions are more about forward economic growth expectations than the tax code, after all.
