ONT-TAXS online is Changing

The Ministry of Finance is upgrading its ONT-TAXS online application on April 28, 2014.

How does this impact you?

  • Clients will experience a short interruption to the application while the ministry implements the upgrade. ONT-TAXS online will be unavailable from noon on Thursday, April 24 to midnight on Saturday, April 26, 2014. Please note that during this time, you will not be able to access your account via the online system to complete any transactions, including filing returns or making payments.
  • The ONT-TAXS online upgrade will change the appearance of ONT-TAXS online but the functionality remains the same. Most activities will be completed through navigation tabs rather than links and buttons. More information will be available on this web page on April 28, 2014.
  • You will continue to enjoy the ease and convenience of online access for a range of activities including filing tax returns, making tax payments and updating account information.
  • You will continue to use your existing ONe-key ID and Password to access ONT-TAXS online.
  • ONT-TAXS online supports Microsoft Internet Explorer 8 or higher. We recommend that you update your Internet browser for better performance, where required.
