Senator Jacqueline Collins, Majority Caucus Whip, 16th Senate District


Dear friend,

During the last several weeks, a number of you have reached out to me with inquiries about a referendum that will appear on the ballot this fall. The proposal would amend a single provision in the state constitution that currently requires the state income tax to be assessed at the same rate on all taxpayers, regardless of income.

If the referendum is approved by voters, a sliding-scale tax rate will be implemented — one that allows higher rates to be charged on higher incomes and lower rates on lower incomes. This sliding-scale tax rate was enacted in 2019. If the referendum is voted down by the voters, the state’s flat income tax rate will stay in place.

For more information, visit .

Below, I’ve also included a few frequently asked questions. I hope this helps clear up any confusion. Please do not hesitate to contact me if you have further questions.
