Where do the state rates come from?
State rates are the Tax Foundation table for 1 January 2026. The optional local figure is that table's population-weighted average, not your city's rate. Type the rate from your receipt if you know it.
Why is New Jersey's local average not added?
The published average local adjustment is slightly negative because some places are outside the statewide rate. The calculator keeps New Jersey at the 6.625% state rate unless you type a different one.
