Explanation of non-payroll Premium Tax impact
The Non-Payroll Premium Tax rate is 10% and has a maximum cap of $350,000/individual or $450,000/joint filer for both payroll and non-payroll income combined. The Premium Tax is a state tax and is deductible from income taxes, whereas health care expenses are not deductible unless they exceed 10% of income (7.5% for people born before 1950). Because state taxes are calculated based on federal deductions, the Premium Tax would be a deduction on state income taxes as well. Considering the reduction in income taxes, the impact of the 10% Premium Tax for income tax payers is reduced to between 8.537% and 5.577% depending on tax bracket. A high-income earner in the federal 39.6% income tax category would pay an effective rate of 5.577%. Because premium liability is limited to $450,000 for joint filers, the after-income-tax impact would be $25,200. This is less expensive than the cost of some family health insurance plans. The ACA does not consider a family health insurance plan to be a Cadillac plan, upon which it imposes a 40% excise tax, unless the cost exceeds $27,500, $2,300 more than ColoradoCare would cost a wealthy joint filer after considering the tax write-off.
This deduction is a substantial reduction in income taxes that the Colorado Legislative Services has projected to be $218.7 million in 2016 (Appendix A), and is forecast in this analysis to be $265.9 million in 2019 for state income taxes alone. The exact amount of income tax savings for Coloradans is difficult to estimate because the savings increase with income, and there is no convenient way to estimate how many Coloradans would be in each tax bracket. However, even assuming that all Coloradans were in one of the lowest tax brackets, 15%, the reduced income taxes (federal and state combined) would be $1,127 million. This savings would certainly be larger because many incomes are in a higher tax bracket. This $1,127 million savings on income tax would be in addition to the savings report for Premiums + OOP.
