How to File a Nil GST/HST Return in Canada: The Key Rule
A nil GST/HST return is a return with no amounts to report. If your business is registered for GST/HST, CRA generally requires a return for every assigned reporting period—even if there were no sales, no activity or no net tax to pay. Use the nil-return option online only when every reportable field truly is zero.

What Is a Nil GST Return?
A nil GST return reports $0 in the relevant GST/HST fields for a reporting period. A business might have no sales because it is seasonal, newly registered or temporarily closed.
A nil return is not the same as missing a filing deadline. Even if the amount payable is $0, the CRA still expects a return from registered businesses for each period.
Do You Have to File a GST Return With Zero Sales?
Yes, if you are registered for GST/HST and the return is required for that period. That includes periods with no business transactions or no amount to remit. If you have closed the account, a final return can still be required.
Do not confuse zero sales with a truly nil return. You might have no sales but still have eligible expenses and input tax credits (ITCs) to report. Verify the records before selecting all zero.
| Business situation | What to check |
|---|---|
| No sales and no reportable expenses | Nil GST/HST return may be appropriate |
| No sales but eligible GST/HST on purchases | Review ITCs; not necessarily a nil return |
| Seasonal business with active GST/HST account | File for the required reporting period |
| Business closing the GST/HST account | File a final return as required |
How to File a Nil GST Return Online
- Sign in to your CRA account for the correct business.
- Choose the GST/HST (RT) account and the period you need to file.
- Select the available filing option, such as the online CRA return.
- If you have no amounts to report, choose "I am filing a nil return (all fields are $0)" when offered.
- Review the period, identity and zero amounts carefully.
- Submit the return and save the confirmation.
The online nil option speeds filing but does not replace checking your bank, invoices and purchase records first.
When Is a Nil GST/HST Return Due?
The deadline depends on whether you file monthly, quarterly or annually. Monthly and quarterly filers generally file no later than one month after the end of the reporting period. Many annual filers have a three-month filing period, with important exceptions for some individuals.
Check the due date in your CRA account rather than guessing. A nil return still needs to be on time. Your reporting frequency does not change just because sales fell to zero.
Common Nil GST Filing Mistakes
- Assuming a $0 balance means no return is needed.
- Choosing nil when business purchases created reportable ITCs.
- Submitting for the wrong GST/HST reporting period.
- Confusing federal GST/HST with BC PST reporting.
- Forgetting the final return after account closure.

What If You Already Missed a Nil GST Return?
Check your CRA account to see which periods are outstanding. Prepare missing returns promptly and review related CRA notices. Filing a late return may trigger follow-up even if no tax is payable.
Accurate bookkeeping services can help confirm whether the return is truly nil. If records are missing, see our bookkeeping cleanup page. For new companies, our CRA compliance guide covers other key obligations.
