In the current discourse, there seems to be some amnesia with respect to when tax cuts occurred, why they occurred, and how they affected Federal budget deficits. Here is some data (read comments to this post.

Figure 1: Federal budget balance as share of GDP (blue), cyclically adjusted budget balance as share of GDP (red), June 2017 estimates. NBER defined recession dates shaded gray. Source: BEA 2017Q4 3rd release, CBO (2017), NBER, and author's calculations.

EGTRRA is the Economic Growth and Tax Relief Reconciliation Act, JGTRRA is the Jobs and Growth Tax Relief Reconciliation Act.
