When you submit a payment or return through Greenshades Tax Service, we will hold onto the submission for a short time to allow you to cancel anything made by mistake. The time we hold onto the submission depends on when it is due. To cancel a submission you have made, you will want to navigate to the historical section of the Tax Service page and find the submission in question. You can then select View to see the details of the submission, and if it is still in the Cancellation Window, you will see a Cancel option.
If you do not see the Cancel Submission option, it is likely past the cancellation window, but you may contact your Tax Service Representative for further details.
