Paying the Tax

The department offers E-check which is actually an Automated Clearing House (ACH) debit method of electronically transferring funds from your bank to the department. Under this method, you authorize the Department of Revenue to electronically transfer your tax payment from your depository into the State’s account. You will be asked to provide the routing information from your financial institution necessary to perform the transaction. Once provided, the information will be retained by the system. You will have the ability to update the routing information at any time or remove it should you wish to pay by another means.

The department also offers payment by credit card through a third-party credit card processing company, (Convenient Payments ). The department also accepts wire transfers and ACH credits although not through the WYIFS system.


Filing Sales and Use Taxes Electronically

The filing of sales and use taxes on the WEB is simplified greatly over filing paper returns. Lookup tables quickly and efficiently identify taxing jurisdictions, automatically calculate the taxes due and eliminate rejection of your tax return for clerical errors, saving taxpayers both time and money.

The following sales and use tax returns can be filed on WYIFS:
