Oregon 52nd District State Representative Mark Johnson is part of a legislative workgroup looking at ways to modify the state tax code that isn’t as income tax based as it currently is.   Johnson says there are a number of possibilities on the table, including a commercial activities tax at a much smaller rate and with a wider base than was proposed in Measure 97 last fall to lessen its impact on any one group of businesses.  Johnson notes a number of states have adopted similar measures, and it would leave the potential to totally eliminate the corporate income tax.  He believes whatever happen will involve a trade-off of some kind.  The Hood River Republican is on the House Revenue Committee.
