There are several ways to pay taxes: By check, by transferring payment using the Electronic Federal Tax Payment System (EFTPS), or by charging payment to a major credit card.
Paying by Check
Most small business owners can pay their tax bill via check made payable to the United States Treasury. Remember that the bulk of the taxes should have been paid through estimated taxes; the check that accompanies the return should be modest.
Corporations cannot pay their income taxes by writing a check to accompany their tax return. They must pay amounts owed by depositing them with an authorized depository (explained below) or by transferring funds through EFTPS.

Some businesses must deposit their taxes through the Electronic Federal Tax Payment System (EFTPS) while others may choose to do so. EFTPS processes over 100 million transactions per year, totaling nearly $2 trillion, with an error rate of 0.18%.

This payment method can be used whether or not returns are filed electronically and enables you to designate up to 120 days in advance the amount of payment to be made and the time of payment.
