The U.S. House of Representatives will soon consider H.R. 7, the "No Taxpayer Funding for Abortion Act." This bill has been scored by the Congressional Budget Office (CBO) as having a negligible effect on both tax revenues and direct spending. That is, any effects the bill may have are so minor and small that they cannot be measured and should be discounted.
Some have claimed in the past that this legislation was a net tax increase, CBO and JCT scores notwithstanding. ATR corrected those accusations back in 2011. The analysis made then still stands today–this legislation is not a net tax increase, and has no interaction whatsoever with the Taxpayer Protection Pledge.
