GST/HST filing deadline for self-employed Canadians: file versus pay

Start with the reporting period shown in the tax account

A GST/HST registrant must file one return for every reporting period, including a nil return when there were no business transactions, no income, or no net tax to remit. A final return is also required when a GST/HST account is closed. The first control is therefore the account's actual reporting period, not a guess based on how often bookkeeping is reviewed.

CRA says the filing due date is determined by the monthly, quarterly, or annual reporting period and that current periods and filing dates appear in the CRA account. Although CRA assigns a default period using revenue, a registrant may be able to elect a more frequent period. Copy the period start, period end, filing deadline, and payment deadline from the live account or personalized return before calculating anything.

Keep the GST/HST return separate from the personal T1 or corporate T2 income-tax return. Some dates can coincide, especially for a qualifying annual sole proprietor, but the returns, program accounts, calculations, and confirmations remain distinct.

Monthly and quarterly filers use the one-month rule

CRA's ordinary rule gives monthly and quarterly filers the same nominal deadline for the return and the payment: one month after the reporting period ends. A monthly period ending July 31 therefore produces an August 31 nominal date, while a quarter ending March 31 produces an April 30 nominal date.

Record the filing and payment dates as separate fields even when they match. That prevents a payment confirmation from being mistaken for a filed return and a return confirmation from being mistaken for a completed payment.

Use the reporting period shown in the account. A calendar-quarter assumption can be wrong when an account changed frequency, the fiscal year differs from the calendar year, or a designated or otherwise unusual period applies.

Annual sole proprietors may pay before they file

Most annual businesses file and make the final payment three months after fiscal year-end. CRA publishes a different split only when all three ordinary sole-proprietor conditions are met: the registrant is an individual with a business, the fiscal year-end is December 31, and the individual had business income for tax purposes for that year.

When all three conditions are true, the GST/HST final payment is generally due April 30 and the GST/HST return is due June 15. If even one condition is not met, the ordinary three-month annual deadline generally applies. A December 31 corporation does not use the sole-proprietor split merely because one person owns it.

For Québec accounts administered by Revenu Québec, its filing-frequency page publishes the same ordinary one-month and three-month paths and an April 30 payment and June 15 filing split for a qualifying individual with business income and a December 31 annual period. Confirm the GST and QST obligations in My Account for businesses because the files remain separate even when a combined return is available.

• Confirm the legal filer: individual, corporation, partnership, trust, charity, or another entity.
• Confirm the exact fiscal year-end and reporting frequency in the current account.
• Confirm whether the individual had business income for tax purposes for that year.
• Do not apply the April 30 and June 15 split to a corporation or to an annual period that does not end December 31.

Apply the next-business-day rule, then check filing method

CRA says that when a due date falls on a Saturday, Sunday, or public holiday it recognizes, the return or payment is on time if received on the next business day. The Thirty North calculator can move a Saturday or Sunday result to Monday, but it cannot determine every federal, provincial, or territorial holiday CRA recognizes. Check the live holiday page and account notice before relying on the adjusted date.

CRA currently requires electronic filing for GST/HST returns for periods ending in 2024 or later, except for charities and selected listed financial institutions. Continuing to file a paper return when electronic filing is mandatory can trigger a penalty; an exemption request is considered case by case.

A balance owing does not prevent electronic filing. Filing and paying are separate actions, so retain a filing confirmation and a payment confirmation rather than one undifferentiated screenshot or note.

Treat instalments and missed dates as separate workflows

An annual filer may have to make GST/HST instalments during the fiscal year even though only one return is filed for the annual reporting period. The annual return deadline and final-payment deadline do not replace those instalment dates.

If a confirmed filing deadline has passed, use the actual return due date and the real amount on the account when screening a late-filing penalty. If a confirmed payment deadline has passed, interest can continue on an overdue amount. Do not blend a penalty estimate, changing prescribed interest rates, instalments, and an unverified account balance into one number.

File the required return even when there was no activity, preserve the submission confirmation, pay through the correct program account, and verify both entries in the live account. Use an adviser or the tax agency when the period, entity, relief, assessment, or account allocation is uncertain.
