We've all been there. No, you can't reverse a GST return that's been recorded but it's not as bad as you might think. If there were just a few missed transactions, you can let them float to the next reporting period or if it's something significant, you can record another return for the day after the one that was prematurely recorded and then just add the numbers from the two reports together. (Note if this is a year-end return then you can generate the return again for the same date as was used the first time)
