The cost of President Biden’s $1.9 trillion coronavirus relief package is on track to double if popular provisions like an expansion of the child tax credit are made permanent, which is exactly what Democrats say they plan to do. The new package includes a one-year expansion of the child tax credit and bolsters other popular tax breaks like the earned income credit. One of the most high-profile tax provisions is an expansion of the child tax credit from $2,000 to $3,600 for children under 6 and to $3,000 for other children.
