Somewhere in your subscription list is a foreign vendor charging you Canadian sales tax. A design tool, a stock-footage library, a scheduling app, a transcription service. The invoice says HST, the amount looks like every other line of recoverable tax in your books, and your bookkeeper codes it accordingly.
For a meaningful share of those vendors, that coding is wrong — and not in a way you can fix later. Tax charged by a business registered under Canada's simplified GST/HST regime cannot be claimed as an input tax credit, and it cannot be claimed as a rebate. It is a dead cost. The only thing that prevents it is giving the vendor your GST/HST number before they bill you.
- Foreign vendors selling digital products and services into Canada register under a "simplified" GST/HST regime once they cross $30,000 in sales to Canadians, and charge tax at the rate of the province you live in.
- Give them your GST/HST number and they don't charge you the tax at all. That is the entire fix, and it lives in your account's billing settings.
- If you don't, the tax you pay is neither an ITC nor a rebate. The Excise Tax Act closes both doors. You've paid 5–15% extra for that subscription, permanently.
- An ITC and a rebate are two different machines. An ITC is netted inside your own return; a rebate is a separate statutory claim on its own form. Knowing the difference is what tells you when there's a way back — and here, there isn't.
- Your only recovery is asking the vendor for a refund or credit note — and they only have two years from the charge to give one.
- Quebec runs a parallel system with the same trap. QST charged under the specified system is not an ITR either, so a Quebec business can be hit twice on one invoice.
Read on for how the regime works, the precise reason the tax is unrecoverable, a clean explanation of ITCs versus rebates, how to tell which regime a vendor is in, and the twenty-minute sweep that stops the leak.
Why a company in California is charging you HST
Until 2021, most foreign vendors selling software and digital services to Canadians simply didn't charge Canadian sales tax. Canadian businesses were supposed to self-assess it; consumers mostly paid nothing. That ended on July 1, 2021, when Canada's digital-economy measures took effect.
Under those rules, a non-resident vendor — along with distribution platform operators and short-term accommodation platform operators — must register under a simplified GST/HST regime once its sales to Canadians exceed $30,000 over any 12-month period. It's the same headline number as the ordinary small-supplier threshold, applied to a very different kind of business.
Source: Excise Tax Act, s. 211.12(2) — a specified non-resident supplier, distribution platform operator or accommodation platform operator is required to register under Subdivision E where its threshold amount for any 12-month period (not beginning before July 2021) exceeds $30,000.
Once registered, the vendor charges tax based on your usual place of residence, not theirs. Same invoice, same vendor, different tax: an Ontario buyer sees 13%, a New Brunswick buyer sees 15%, an Albertan sees 5%. The Act builds the province out of billing addresses, IP addresses and payment data — which is why your subscription receipt sometimes changes when you move.
Source: Excise Tax Act, s. 211.14(1) and (3) — the supply is deemed made in Canada, and in the participating province where the recipient usually resides; s. 211.11 lists the residence indicators used to determine that.
You're a "specified Canadian recipient" until you prove otherwise
Here's the mechanism, and it's worth understanding precisely, because it explains everything that follows.
The simplified regime only applies to a specified Canadian recipient. The Act defines that as someone who meets two conditions: their usual place of residence is in Canada, and they have not given the supplier satisfactory evidence that they're registered for GST/HST under the ordinary rules.
Source: Excise Tax Act, s. 211.1(1), definition of "specified Canadian recipient" — paragraph (a) requires that the recipient has not provided evidence satisfactory to the Minister of registration under Subdivision D of Division V (ordinary GST/HST registration).
You control the second condition entirely. Put your GST/HST number in the vendor's billing settings and you stop being a specified Canadian recipient. The vendor no longer charges you the tax — not because they're doing you a favour, but because the charging rule no longer reaches you.
One limit worth knowing: this is a business switch, not a discount code. The Act specifically prohibits providing evidence of GST/HST registration to a simplified registrant in respect of a supply made to a consumer. Your household streaming subscription isn't a business purchase, and putting the company's number on it isn't a grey area — it's expressly barred.
Source: Excise Tax Act, s. 211.2 — prohibition on providing evidence of ordinary registration in respect of a supply made to a consumer.
Why the tax is a dead cost
Most owners, told they can't claim the ITC, reach for the obvious backstop: fine, then I'll claim a rebate for tax paid in error. That instinct is usually right. It fails here for two separate reasons, and both are worth understanding.
First, it wasn't paid in error. Because you hadn't given the vendor your number, you were a specified Canadian recipient, and the tax was genuinely payable on that supply. There is no mistake to unwind. The system worked exactly as designed — it just designed you into the consumer lane.
Second, the Act closes the doors explicitly. Section 211.17 is unusually blunt: no input tax credit, rebate, refund or remission is to be credited, paid, granted or allowed to the extent it relates to an amount collected as tax by a person registered — or required to be registered — under the simplified regime.
Source: Excise Tax Act, s. 211.17(1). Note the phrase "or required to be registered" — the restriction also captures a non-resident who should have registered and didn't. See also CRA Guide RC4022: failing to provide your registration number "may result in difficulties in recovering the GST/HST you paid… since the GST/HST paid cannot be claimed as an ITC or a rebate."
The same design logic runs the other way, too. Registration under the simplified regime isn't "registration" for the rest of the Act — which is why simplified registrants can't claim ITCs on their Canadian costs either. It's a deliberately one-way, low-administration pipe: collect tax, remit tax, claim nothing.
Source: Excise Tax Act, s. 211.1(2) — in the rest of Part IX, a reference to registration does not include registration under the simplified subdivision.
There is one small consolation, and it's the same split we draw in no receipt, no GST number: you lose the tax credit, not the deduction. Unrecoverable GST/HST forms part of what the subscription actually cost you, so it stays in the expense for income-tax purposes. If you're in a corporation paying tax at the small-business rate, that softens the blow by roughly a tenth of the amount. It doesn't come close to making you whole.
An ITC and a rebate are not the same thing
People use these words interchangeably, and it costs them clarity at exactly the moments clarity matters. They're two different mechanisms with different eligibility, different paperwork and different deadlines.
An input tax credit is how the GST/HST system stays neutral for businesses. You paid tax on something you bought for your commercial activity, so the system gives it back — by letting you subtract it from the tax you collected. Its defining features: you must be a registrant at the time, it's proportional to how much you use the thing commercially, and you claim it on line 108 of your own return. Nobody sends you a cheque; you simply remit less. It's a netting mechanism.
Source: Excise Tax Act, s. 169(1) — the ITC formula A × B, where A is the tax that became payable during a reporting period in which the person was a registrant, and B is the extent of use in commercial activities.
A rebate is something else entirely: a refund Parliament wrote into the Act for a specific listed circumstance. Tax paid in error. Public service bodies — charities, non-profits, municipalities, schools, hospitals — recovering a fixed percentage of tax they can't claim as ITCs. New housing. Certain exports and non-resident situations. Its defining features: you often don't need to be a registrant, you claim it on a separate application form, and the CRA pays it out.
Source: Excise Tax Act, s. 261 — where a person pays an amount as tax in circumstances where it was not payable, the Minister shall pay a rebate, provided the application is filed within two years after the day the amount was paid.
| Input tax credit | Rebate | |
|---|---|---|
| What it is | Recovery of tax you properly paid on business inputs | A statutory refund for a specific listed situation |
| Who can claim | GST/HST registrants only | Registrants and non-registrants, depending on the provision |
| Where you claim it | Line 108 of your regular GST/HST return | A separate rebate application form |
| How you receive it | You remit less — it nets against tax collected | The CRA pays the amount to you |
| Typical trigger | Every business purchase carrying GST/HST | Tax paid in error; public service body status; new housing; certain exports |
| Time limit | Generally four years to claim it in a return (two for larger, "specified" filers) | Generally two years from the day the tax was paid |
| Simplified-regime tax | Blocked | Blocked (with narrow exceptions) |
Source: ITC claim deadline — Excise Tax Act, s. 225(4), which sets a four-year window for most registrants and a two-year window for "specified persons" (broadly, larger filers and listed financial institutions).
Those narrow survivors are worth naming, because they're the difference between "no" and "no, unless." Section 211.17 preserves public service body rebates, and it preserves a section 261 rebate for tax paid in error — but only for someone who was not registered under the ordinary GST/HST rules at the time the tax was collected.
Source: Excise Tax Act, s. 211.17(2) — exceptions for deductions under ss. 231(1), 232(3) and 234(3), rebates under ss. 259 and 259.1 (public service bodies), and s. 261 rebates in respect of amounts collected from a person at a time when that person was not registered under the ordinary rules.
Read that twice, because it's the sting. The exception is written for people who genuinely had no way out — a small supplier under the $30,000 threshold, say, who isn't registered and couldn't have given a number. If you are registered, you had the switch and didn't flip it, and the rebate isn't there for you.
The only way back is through the vendor
Since the Act blocks you from recovering the tax through the CRA, the remaining route runs through the supplier. Section 232 lets a supplier who charged tax refund or credit it to the customer and then deduct that amount from their own net tax, issuing a credit note to document it.
Two constraints matter. The window is two years from the day the amount was charged or collected. And the provision says the supplier may do this — not shall. It's their call. Some vendors handle it routinely through a support ticket; some won't engage at all.
Source: Excise Tax Act, s. 232(1) and (3) — a person who charged or collected an amount as tax in excess of what was collectible may, within two years, refund or credit it, and must issue a credit note containing prescribed information. Revenu Québec gives the same instruction on the QST side: a registrant who has already paid the tax "has to deal directly with the supplier or operator to obtain a refund."
So the practical sequence is: fix the billing settings first so the bleeding stops, then work backwards through the last twenty-four months asking for credit notes. Anything older than that is simply gone.
Not every foreign vendor is a simplified registrant
This is where people over-correct. Plenty of non-resident businesses are registered under the ordinary GST/HST rules — often because they carry on business in Canada or chose to register normally. Tax from those vendors is fully claimable, exactly like tax from a supplier down the street. "Foreign vendor" does not mean "no ITC."
There are two registries, and they're separate:
- The GST/HST Registry — confirms ordinary registration numbers. If the vendor is here, their tax is claimable subject to the usual documentary requirements.
- The Simplified GST/HST Registry — a separate list the CRA is required to publish of digital-economy businesses registered under the simplified regime. If the vendor is here, the tax is not claimable.
Source: CRA, Confirming a simplified GST/HST account number — "If you are a business registered for the normal GST/HST in Canada purchasing goods or services from a business listed in the Simplified GST/HST Registry, you must provide that other business with evidence that you are registered for GST/HST in order not to be charged the tax."
In Quebec there's a faster tell, printed right on the invoice: a QST number issued under the specified system contains NR, while an ordinary Quebec registration number begins with TQ. Two letters tell you whether the tax is recoverable.
One footnote for Quick Method filers: you're not claiming ITCs on operating expenses anyway, so this changes less for you than for a regular filer. It still costs you real money — you'd rather not be charged the tax at all — so the billing-settings fix is still worth doing.
The same trap, a second time
Revenu Québec built a mirror of the federal regime. Suppliers outside Quebec that sell into the province register under the specified registration system and collect QST from Quebec consumers. The rules track the federal ones almost exactly:
- You cannot claim an input tax refund for QST paid to a supplier registered under the specified system — even if the purchase was entirely for your commercial activities.
- You avoid the charge by telling the supplier you're registered and giving them your TQ number before the transaction.
- If you've already paid it, you deal directly with the supplier for a refund. There's no route through Revenu Québec.
Source: Revenu Québec, Suppliers Outside Québec and Input Tax Credits (ITCs) and Input Tax Refunds (ITRs).
The consequence for a Quebec business is that a single foreign invoice can carry two unrecoverable taxes — 5% GST and 9.975% QST — turning a $200 monthly subscription into roughly $230 of permanent cost. Nearly 15% on top of every affected line item, every month, indefinitely.
A twenty-minute sweep that stops the leak
This is one of the rare tax problems with a genuinely simple remedy. It just has to be done deliberately, once, and then maintained.
- Pull twelve months of subscription charges from the business credit card. Every foreign vendor, every recurring line.
- Flag any invoice showing Canadian tax from a vendor with a foreign address. Those are your candidates.
- Log in to each one and find the billing or tax settings. Enter your GST/HST number — and your QST number if you're in Quebec. Most vendors have a field for exactly this; it's often labelled "tax ID" or "VAT/GST number."
- Check the ambiguous ones against both registries before you change how you code them. Ordinary registration means the ITC is fine.
- Open a ticket for anything charged in the last two years asking for a refund and a credit note. Some vendors will, some won't. It costs you an email.
- Tell your bookkeeper to stop claiming ITCs on the affected vendors — and to route new foreign invoices to you before the tax code gets set.
- Make it a signup habit. Any new tool, the tax number goes in during setup, not later. Later is where the money goes.
Colin paid 15% extra for two years
Meet Colin, who runs Beacon Row Media, a four-person video production studio in Saint John, New Brunswick. His business is almost entirely software: editing suites, a stock-footage library, a motion-graphics template marketplace, a client-review platform, a transcription service, cloud storage, two font licences. Eleven foreign vendors, roughly $1,200 a month, all charging him HST at New Brunswick's 15%.
Every one of those invoices was coded with HST recoverable. It looked right. The invoices said HST, the amounts were correct, the vendors were legitimate. Nobody had a reason to look twice.
When we picked up the file, we ran his vendor list against the Simplified GST/HST Registry. Nine of the eleven were simplified registrants — about $14,400 a year of spend, carrying $2,160 a year in HST that had never been claimable. He'd been filing that way for just over two years. Roughly $4,300 of claimed input tax credits weren't credits at all.
He hadn't been careless. He'd been charged a tax that looked identical to every other recoverable tax in his books — and there was nothing on the invoice to tell him otherwise.
The exposure cut both ways. The prior claims were wrong and had to come out, which meant an adjustment and interest. And going forward, that $2,160 a year was pure cost he'd been unknowingly absorbing while believing he'd get it back.
What should have happened
Ten minutes, at signup, for each vendor. Colin's GST/HST number entered in nine billing portals means nine vendors stop charging him tax entirely — no ITC needed, because there's no tax to claim. That single afternoon of work is worth $2,160 every year, permanently, and it removes an audit exposure that was quietly compounding.
We did the sweep, corrected the coding, and went back to all nine vendors. Four issued credit notes for amounts inside the two-year window, recovering about $1,500. The rest either declined or the charges were too old. That's the shape of this problem: prevention is cheap and total, recovery is partial and depends on someone else's goodwill.
The switch is on the invoice, not the return
Almost every GST/HST problem gets solved on the return — you find the receipt, you claim the credit, you fix the coding. This one doesn't. By the time a simplified registrant's invoice reaches your books, the outcome is already fixed: the tax was properly charged, and the Act denies you both the credit and the rebate.
Which makes it a rare thing in tax — a problem with a complete, permanent fix that costs nothing but attention. Go through your subscriptions, put your GST/HST number where the vendor asks for it, and the leak closes for good.
