The GST "NEXT return to file" dates are incorrect how do I get to the current dates?

Hello melacct,

The "Next return to file" date depends on how you set up your filing frequency. 

To change the setting:

1. Click Taxes, and then click Manage sales tax.
2. Click the Add rate drop-down, and click Edit agency settings.
3. In the Edit tax agency settings, click the Next period starts and the Filing frequency.
4. Click Save.
