The calculator can include the proposal to raise the first tax bracket in the 12/32% scale from 120,000 PLN to 140,000 PLN (the so-called second bracket). You can enable this with the "Check" toggle in the banner at the top of the comparison form. The simulation is applied consistently to all compared options where it matters (including 12/32% scale, UoP, joint filing with spouse). By default, current brackets provided by law apply.
