Yes — you can pay your federal taxes with a credit or debit card through IRS-authorized payment processors like Pay1040 or ACI Payments. Credit card payments include a processing fee of about 1.85%–1.98% of the amount paid. It can make sense if you earn credit card rewards worth more than the fee — but the fee reduces the net benefit. Paying with a debit card typically costs around $2.50 flat. You can also pay taxes directly from a bank account for free at IRS.gov's Direct Pay. Credit card payments don't reduce or defer your tax obligation, but they can buy you time if you're short on cash.
