How to read the 2018 vs 2019 differences

Standard deduction deltas

A higher standard deduction lowers taxable income before brackets apply. The single deduction moved $200 (up from 2018 to 2019); MFJ moved $400. Large jumps usually mean a law change (TCJA) or a high-inflation COLA year.

Rate schedule vs indexing

Both years use the tcja schedule, so most differences are inflation-adjusted thresholds—not new rate percentages.

Taxable-income examples

The sample tax table holds taxable income fixed so you can isolate bracket/threshold changes. Real paychecks also change with deductions, FICA wage bases, and credits—so treat the dollar differences as directional, not a full return comparison.
