Get your taxes done using TurboTax

@DA248   I have included a screenshot when paying taxes with a credit card using TurboTax.  The convenience fee is 2.49% as shown at the bottom of the screenshot.

Also, see the fees when paying federal taxes using the processors on the IRS payment website - https://www.irs.gov/payments/pay-your-taxes-by-debit-or-credit-card
