Putting money into the IRS is basically a free money printer for the US government and it's only deep corruption that keeps it so poorly funded.
The Federal government has a century of empirical data on this. They set their targets accordingly, which as a heuristic is roughly optimal at around 10:1. This may not be intuitive to you. It wasn’t to me either until I worked at a Federal audit agency. Most of it actually makes sense once you understand the bigger picture.
