It was no real surprise given the amounts paid in recent months, but the mid-September quarterly payment of income taxes by corporations continued to be very strong. With most all of the September payment now in the books, amounts so far this month have been about 57 percent above payments through the comparable point in September last year, and 44 percent above the comparable amount in September 2019. That guarantees that payments for the federal fiscal year, which concludes at the end of the month, will be well above those not just in 2020, but in pre-pandemic years as well (see chart below). For the fiscal year it looks like gross payments (that is, not net of refunds received by corporations) will be more than 50 percent above the amounts in each of the past three years. They will also be well above those in 2017, even though corporate income tax rates were much higher back then (a top 35 percent rate, before the tax cuts that took effect on January 1, 2018, reduced the top corporate tax rate to 21 percent). The main question is why corporate income tax payments are so high.

We won’t know for a couple of years or more, when data from tax returns for this year become available, what sources of income are responsible for the jump in taxable corporate profits and corporate tax payments. But we can guess at some of the main influences.

While corporate tax payments have surged, tax refunds to corporations have not (see chart below). Through almost the entire fiscal year, refunds have remained close to those in recent years. The stability of refunds in 2020 and 2021 compared to earlier years has been a surprise, given the legislation enacted last year that was intended to get large refunds out to corporations. The legislation, which we have discussed several times in previous posts, allowed firms to use losses in 2018 and 2019 (as well as in 2020) to receive refunds of past taxes paid up to five years earlier. Delays by the IRS in processing the refund applications, because many of the refunds required paper processing, have been a problem during the pandemic and could be delaying some refunds even about a year and a half after the legislation was enacted.
