Payment Only Transactions

The TSC also allows payment-only transactions for taxpayers making payment for an existing business tax bill or for tax due reported on a business tax return that cannot be filed electronically. After you log into your account in the TSC, follow these steps for a payment-only transaction:

  1. On the TSC Main Menu under Select a Payment Option, choose Make Payment Only.
  2. Select the tax type from the drop down box for the payment you are making.
  3. Select the period ending date from the drop down box.
  4. Enter the dollar amount of the payment and follow the prompts to initiate the payment.

NOTE: "Make Payment Only" is not to be used when submitting regular income tax withholding payments. This option is designed to pay past due billings and to initiate payments for tax types whose associated forms are not currently supported by the TSC. You must select either the Withholding Wage or Withholding Non-wage link on your TSC Main Menu to ensure that your withholding payments are properly credited to your account.
