A solid chair needs four legs to be steady. Oil tax credit reform is one leg on it`s own, considering the growing large amounts of subsidies for so-called "new" oil pumped from the old legacy leases, that will stay on the state`s side of the ledger from now on.  
If we taxed on the net return after deducting transportation production and delivery costs, instead of a false floor on a moving gross formula, we wouldn`t need this conflicted corrupted convoluted land mine of a tax system known as SB21. We still need broad based taxes and ongoing precise cuts where they can be made without further tearing the fabric of our society in Alaska. The fourth leg is a POMV plan to endow the use of a certain percentage of the fund`s earnings each year for state government use each year.  This can be done keeping the dividend around where it is now or higher later even. Though a portion of our dividends would be taxed by the feds,  that would be deductible against the state tax.  Kudos to the House.
