We've used TaxAct for several years. This year, we owed over 7K on our Federal taxes and opted to pay by credit card, all of which is handled by the TaxAct site when you file your return. We completed the filing and the payment. When we printed our return and forms, they said we had submitted our payment. Nothing ever showed up on the credit card; it was never charged. Now the TaxAct site says we 'elected to pay at a later date.' This is absolutely NOT true. We will now have to pay a PENALTY because of this screwup, and TaxAct refuses to take any responsibility. And it is almost impossible to contact them to speak with a representative to try to fix the problem. In short, AVOID TAXACT!
