CHERRY HILL, N.J. — In New Jersey and California, top Democratic officials want to let people make charitable contributions to the state instead of paying certain taxes. In Connecticut and New York, officials are exploring a switch from income taxes to new ones on payroll. A few governors have even called for tax cuts. The ideas are bubbling up as state lawmakers begin their 2018 sessions and assess the effects of the Republican tax overhaul that President Donald Trump signed into law last month.
