It's vital you're able to edit your tax filing report. I'll be happy to assist you with this.
If you're referring to changing the filing frequency, here's how:
Note: Your filing frequency can differ between your federal and provincial return. Make sure you're editing the right filing frequency. If you'd like to change the filing frequency for your business, you'll have to get permission from the Canada Revenue Agency. Visit Canada.ca to learn more. Once your business has received permission, follow the steps below to change your filing frequency in QuickBooks Online.
Select Taxes from the left menu.
Select Sales Tax at the top.
Click on Manage Sales.
On that page, click the drop-down arrow beside Add Rate.
Select Edit Agency Settings.
Otherwise, if you'd like to edit taxes you've already filed, you'd have to contact our support team using this link. Let me know if you have questions.
