That's fair.
I'd still personally segment it as "no tax, health care costs," if I was charting out my annual spending, but since money is fungible, you can definitely shift that to say that the extra healthcare premiums aren't "health insurance" costs but "federal income tax" costs.
Regardless, when it comes to plotting your budget, you should see close to 0% taxes, even if your healthcare budget is higher due to the income.
