Vice President Kamala Harris on Friday announced agenda items for her first 100 days as president, including a $6,000 tax credit for parents of young children.

Democrats have long called for an increase in the child tax credit, but the amount proposed by Harris is higher than any Democrat before it – and it is exactly $1,000 more than what Republican vice presidential candidate JD Vance proposed earlier this week.

Harris portrayed the $6,000 stimulus check as part of a broader economic policy that also includes aid for first-time home buyers and a crackdown on “price gouging” by grocery companies.

Harris’ campaign said she is calling for “up to $6,000 in tax relief for middle- and low-income families during their child’s first year, when a family’s expenses are at their highest – for cribs, diapers, car seats and more – and many parents are still forced to forgo income by taking time off from work.”

On Sunday, Vance proposed a $5,000 child tax credit in an interview with CBS News, but apparently acknowledged that it was not a very realistic idea.

“I would like to see a child tax credit of $5,000 per child,” Vance said. “But of course you have to work with Congress to see how possible and feasible that is.”

Vance mocked Harris’ suggestion on Friday.

“Kamala Harris will soon propose that we finish the border wall and make America great again,” he wrote on social media. “No one should be fooled by the fake campaign copying President Trump’s vision.”

In recent years, however, it has been the Democrats, not the Republicans, who have pushed for an expansion of the child tax allowance.

The scheme works by giving households with annual incomes of up to $400,000 a tax credit worth $2,000 per child, and allowing lower-income households to receive part of the tax credit as a cash payment.

In 2021, Democrats and President Joe Biden temporarily increased the exemption to up to $3,600 per child, with the full amount available as a cash payment paid out monthly by the IRS. This arrangement was similar to the child benefit that is standard in other developed countries and significantly reduced poverty in households that received it.

A bipartisan proposal that passed the House earlier this year combined a more moderate expansion of the child tax credit with a series of tax breaks for businesses. But most Republican senators opposed the bill when the Senate considered it earlier this month, and Vance skipped the vote.

Neither Harris nor Vance have provided any details about their child tax credit ideas beyond the big numbers, and neither is likely to receive serious consideration in Congress – at least not this year.
