I owe taxes for fed and state. I know there is a third party processing fee. If I pay with my debit card, will it be a flat fee or a percentage of what is owed?

For federal look at the payment page <a rel="nofollow" target="_blank" href="https://www.irs.gov/payments">https://www.irs.gov/payments</a>

The taxes are not due until 4/15/19 so do NOT pay them too much  in advance if you are going to put it on a CC ... you can file the returns anytime  and pay later ... you may be able to pay off the entire amount or at least some of it so the fees would be less.
