How to File a GST/HST Return in Canada: A Creator's Step-by-Step Guide

This walkthrough assumes all of the following:

• You are a Canadian sole proprietor or individual creator already registered for GST/HST
• You are filing the regular method, not the Quick Method of accounting
• You are filing an ordinary return for one reporting period, not an election, rebate-heavy return or special schedule
• You can identify which of your creator supplies were taxable, zero-rated, exempt or outside the GST/HST rules
• You have records for the period: invoices, payout reports, expense receipts and GST/HST details

Start in your CRA account, not with a date you remember from last year. Your account shows the reporting period that is due and the exact deadline for that return.

• Monthly or quarterly filer: the return and payment are generally due one month after the period ends
• Most annual filers: the return and final payment are generally due three months after the fiscal year-end
• Annual sole proprietor with a December 31 year-end and business income: payment is due April 30, while the return is due June 15
• No business activity for the period: you still file a nil return — a return with all $0 amounts

A weekend or CRA-recognized public holiday can move a deadline to the next business day. Read the CRA's current filing and payment deadline guidance for the rule that applies to your account.

Do not start with the deposits that landed in your bank account. A bank deposit is often a net payout after platform fees, foreign-exchange conversion or a payment processor cut. Build the return from the underlying sales, invoices and expense records for the reporting period.

• Your Business Number and RT account details
• The reporting period's from and to dates
• Brand-deal invoices and the GST/HST charged or collectible on each one
• Platform payout reports for YouTube, TikTok, Twitch, Patreon, affiliate platforms or other sources you use
• A note for cross-border or zero-rated supplies, where that treatment has been confirmed
• Receipts and invoices showing GST/HST paid on eligible business expenses
• Any GST/HST instalments already paid, plus any specific adjustments or rebates that apply
• Your working spreadsheet or bookkeeping export, with amounts converted to Canadian dollars where required

For a regular-method return, the CRA's electronic form guides you through the applicable lines. These are the numbers a solo creator usually needs to understand first.

The example assumes one ordinary taxable Canadian supply, the regular method and no other sales, adjustments or instalments. A creator with platform, cross-border, exempt or zero-rated income needs to classify those supplies before copying this math.

The CRA's built-in GST/HST NETFILE flow is usually the clearest option if you are filing your own return. You can use My Business Account or your Business account inside the CRA sign-in.

• Sign in to your CRA account and select your Business account
• Choose GST/HST and your RT number
• On the GST/HST account overview, select File a return
• Choose the return type and reporting period shown in your account
• Select the situations, rebates or schedules that apply; choose the nil-return option if all fields are $0
• Enter the amounts from your worksheet and follow the form's prompts for sales categories
• Review every amount, especially the reporting period, sales, GST/HST collected and ITCs
• Check the certification box and select Submit
• Save the six-digit confirmation number and a copy of the return

The CRA's detailed instructions for filing in your CRA account include the current screen-by-screen sequence and explain what the confirmation number means.

If the return shows a balance owing, pay it by the payment deadline for that reporting period. In My Business Account, you may be offered a Proceed to pay option; you can also use the CRA's online payment methods or your bank's bill-payment service.

• Positive net tax: you generally have a balance to remit
• Negative net tax: you generally have a refund to claim
• Annual sole proprietor with a December 31 year-end and business income: the net tax payment is due April 30 even though the return is due June 15
• If you have an instalment arrangement, include the applicable instalments in the return as the CRA instructions direct

Use the CRA's current payment instructions for the correct payment option. Keep proof of payment with the return rather than assuming that a bank transaction by itself explains which reporting period it belongs to.

Filing is not the end of the record. Save one folder for the reporting period with:

• The submitted return or a PDF/printout of the amounts you entered
• The six-digit CRA confirmation number
• Your sales worksheet and source reports
• Brand invoices and evidence of GST/HST charged or collectible
• Receipts and invoices supporting ITCs
• Payment confirmation, or the refund details shown in your CRA account
• Notes explaining unusual platform, cross-border, gifted or barter treatment

The CRA says you should usually keep GST/HST records for six years from the end of the year they relate to. See its GST/HST records guidance for the current retention rule and exceptions.

• Putting GST/HST into the sales number instead of reporting the sales and tax on their separate lines
• Using bank deposits as revenue and missing gross platform reports, unpaid invoices or fees that need separate treatment
• Reporting only invoices that were paid, even though GST/HST may be collectible when the invoice was issued or payment became due
• Claiming all GST/HST on a mixed personal and business purchase instead of the reasonable business portion
• Treating every income-tax deduction as an ITC without checking whether GST/HST was actually charged and whether the purchase supports a commercial activity
• Leaving out zero-rated or exempt revenue because no GST/HST was charged
• Skipping a nil return because there was no activity
• Filing a second return to fix a mistake instead of using the CRA's adjustment process
• Submitting the return but forgetting to pay the balance by the payment deadline

Do not file a duplicate return for the same period. The CRA says to use the Adjust a return option in your online account when the period is eligible, or send the required correction information to the applicable tax centre. Keep a note of what changed, why it changed and which source documents support the correction.

You can read the CRA's post-filing adjustment guidance before changing anything. If the error involves missed registration, missed tax charges or several old periods, ask for professional help.

Filing on your own is reasonable when the facts are clean. Get a second set of eyes before submitting if any of these describe your return:

• You are filing your first return and are not sure which creator income is taxable, zero-rated, exempt or outside scope
• You have significant income from platforms, foreign agencies, affiliates, digital products or barter arrangements
• You registered voluntarily and are claiming large ITCs for gear, a home office, travel or other mixed-use costs
• You elected the Quick Method, a special method or a different reporting period
• You have Quebec QST, another provincial sales-tax registration or a related business
• You crossed the threshold but did not register or charge GST/HST when you may have been required to
• You need to amend several prior returns or cannot reconcile your records to the bank and platform reports

• File your GST/HST return — CRA overview
• Instructions for preparing a GST/HST return
• Reporting requirements and deadlines
• Remit or pay the GST/HST collected
• GST/HST records to keep

Cadence does not file your GST/HST return or replace tax advice. It helps keep the source records together before you open the CRA form:

• Platform payouts and brand payments in one record
• GST/HST details attached to expenses and invoices
• Notes for cross-border, gifted or unusual transactions that need review
• A cleaner worksheet to take into the CRA filing flow or to an accountant
