Can I pay part of my tax due on one credit card and the remainder on the other credit card?

[AnthonyC · Accepted solution]

Yes, but you won't be able to directly use two different cards to make a tax payment through Turbotax.  You will have to use the IRS site to make two separate payments.  You can use the link below to make payments by credit card.  (You will actually save some money on the processing charge using the IRS site anyways as they charged a lower amount when you pay directly on their site).

Inside TurboTax, you should select “pay by check” during the filing process.  It will produce a payment voucher for you, which you can then ignore and make the credit card payments online later.
