Services previously available through Revenue Online that will continue include individual income tax NetFile and consumer use tax online filing. The department will centralize all its online services, including those for sales, wage withholding and fuel taxes, in Revenue Online during 2011. In September, online filing of corporation, fiduciary and partnership returns (and amended returns) will be available through Revenue Online in formats similar to individual income tax NetFile.


Note: Filing and account maintenance services in Revenue Online require users to install the Microsoft Silverlight plug-in. Revenue Online offers a user-friendly display that is not possible unless the Silverlight plug-in is installed. If you already have Silverlight on your computer, you may need to install an upgrade version. For more information about Silverlight, see Microsoft’s Web site:
