Washington tax writers say they have adjusted the sweeping legislation to improve the child tax credit, a demand of Sen. Marco Rubio.
Details have yet to emerge and Rubio's office says he will review the details.
The tax package would double the per-child tax credit from $1,000 to $2,000. The bill originally made a portion of the credit — $1,100 — available to families even if they owe no income tax. Noem says that amount has been increased to $1,400. Rubio said he wanted the $1,100 figure increased, but he did not say by how much.
Low-income taxpayers would receive the money in the form of a tax refund, which is why it's called a "refundable" tax credit.
