I shut the workshop for a month to help my mother move. There were no chair deliveries, no new invoices and no cash in the till. When the HST reminder arrived, I nearly filed it with the advertising mail.
Nothing had happened, I thought. Then I checked the business account and saw the insurance payment and a supplier credit.
Check whether the period is really nil
A GST/HST registrant must file for each reporting period, including periods without business activity or net tax to remit. A nil return is appropriate when there is genuinely nothing to report; "no sales" is not the whole test. CRA's filing requirements.
I reviewed sales, purchases, credits and adjustments for the exact period. The bank balance alone could not tell me which GST/HST entries belonged on the return. Not every expense carried recoverable tax, and a quiet month could still contain relevant transactions.
I also checked that I was looking at the right account and reporting dates. A monthly bookkeeping habit does not change an assigned quarterly or annual GST/HST reporting period.
Keep proof that the return was filed
Once the figures were settled, I used the appropriate electronic filing method and saved the confirmation with the period's worksheet. A zero payment does not prove that a return was submitted.
If I eventually close the business, I will need to address the GST/HST account formally and file the required final return. Simply stopping invoices does not close the account.
The reminder now goes in the same calendar as the busy periods. I don't assume the return contains zeros, and I don't assume a quiet business has no filing duty. I start with the records for that period and work from there.
Checked October 20, 2026. See annual GST/HST deadlines before using a personal income-tax date for the business account.
