THE HIGH COST OF EXPANDING THE CHILD TAX CREDIT.

• Author: Suderman, Peter

AT THE END of 2021, not quite a year into Joe Biden's presidency, something unusual happened: Congress actually allowed a massive government program to expire. That program was the expanded child tax credit, which had been enacted as a temporary program under the American Rescue Plan (ARP), a roughly $2 trillion spending package passed exclusively with Democratic votes in March 2021.

A year after the expansion expired, however, Democrats began looking for ways to bring it back. The cost of doing that would be very high.

The ARP raised the maximum child taxcredit from $2,000 to $3,600 per child for families making up to $150,000 a year. The one-year program made the credit fully refundable, meaning that people would qualify for it even if they owed no income taxes. That change expanded the benefit to millions of households that previously had earned too little to qualify.

The ARP also turned what had been an annual lump sum around tax season into a monthly payment that in many cases was directly deposited into parents' bank accounts. In effect, the law set up a program of monthly checks, sent directly to the bank accounts of most families.

Although the program was initially designed as a one-year expansion, supporters hoped it would become permanent. As The New York Times reported in January 2022, the benefit "was never intended to be temporary," and "many progressives hoped that the payments, once started, would prove too popular to stop."

Yet at the end of the program's first year, after paying out about $80 billion, Congress declined to extend the program. Even with Democrats in control of both the House and the Senate, there simply weren't enough votes to keep it going. Sen. Joe Manchin, the moderate Democratic senator from West Virginia, was vocally opposed, citing cost concerns and warning that the expanded eligibility would subsidize unemployment. Progressive ambitions were foiled--or at least they seemed to be.

In late 2022, after Democrats performed far better than expected in the midterm elections, picking up a seat in the Senate as Republicans gained only a narrow majority in the House, some Democrats pushed to restart the program. Sen. Michael Bennet (D-Colo.) argued that a renewed expansion...
