The Fine Print

Our Verdict
The best rate for paying taxes with a credit card this year is a 1.87% rate, see our Complete Guide To Paying Your Federal Taxes With A Credit Card for more info. For Mastercard payments, Plastiq is now the best rate at 1.75%, and it could be especially useful for meeting signup bonuses on cards like Barclay’s Arrival Plus or many of Citi’s cards.
Note that the Plastiq system indicates that the payment is sent via check and will take some time to get there. When I input the details of a payment to be sent today, Plastiq showed me a delivery date of March 28; don’t use this at the last moment.
