An electronic check (e-check) may be used to pay many of the tax obligations for both businesses and individuals online. This method of payment is becoming widely used not only for the convenience and ease, but also because it does not incur additional fees associated with other types of payment such as credit cards. When using e-check on the Web, you will need your social security number for individual transactions or the business identification number, which is usually the federal identification number when paying business obligations. In addition, an assigned 4-digit Personal Identification Number (PIN) will be needed to make a payment. Screens will be provided to prompt you in providing the required information. You will be asked the routing number of your bank, your account number and the amount you wish to pay. After entering this information and submitting it, you will receive an online confirmation for your records.
