Zero-rated is not exempt, and the difference is your input tax credits
Basic groceries are zero-rated under the Excise Tax Act: taxable supplies at a 0% rate. That single word — taxable — is what preserves your input tax credits. The 13% HST paid on flour, film, freight, hydro, repairs and the new filler all comes back, while an exempt supplier in the same building would eat every dollar of it. A producer whose output is mostly basic grocery is therefore structurally in a refund position: credits in, almost nothing collected out.
The trap is treating the two words as synonyms. We have seen zero-rated producers under-claim for years because "we don't charge HST" slid into "HST isn't our problem". It is your problem in the best possible way — the return pays you.
Your SKU list is also a tax-code list
Few catalogues are purely basic grocery, and the rate is set by the product, not the customer. Frozen entrees, sauces, packaged bread and plain nuts leave the dock at 0%; carbonated beverages, candy and confectionery, chips and other salty snacks, and granola bars leave at 13% — granola products are taxable however healthy the label reads. Each SKU gets mapped to its rate once in the invoicing system, so every wholesale invoice carries the right tax line by line.
Getting a code wrong costs real money in one of two directions: charge 13% on a zero-rated line and the retailer's payables team bounces the invoice; miss 13% on a taxable line and the CRA still wants the tax you never collected. On an assessment that arithmetic lands on you, plus interest.
Elect the filing frequency that pays you fastest
Registrants under $1.5 million in annual taxable supplies default to filing once a year — the wrong default for a refund filer. An election on Form GST20 moves you to monthly or quarterly, and for most producers the choice looks like this:
| Filing frequency | Who it suits | What it does to your cash |
|---|---|---|
| Annual | Businesses that owe a little and want one filing | Your refund waits up to a year — you finance the CRA |
| Quarterly | Refund filers whose books close slowly | Cash back four times a year; a workable middle |
| Monthly | Refund-position producers with a monthly close | The refund becomes a routine cash inflow, twelve times a year |
Refund claims get looked at — a first claim or a spike often triggers a pre-payment verification where the CRA asks for the invoices behind the credits. We keep the file ready before they ask: supplier invoices captured digitally, registration numbers on the large ones, and the claim reconciled to the ledger. When a review letter does arrive, CRA Audit & Review Support answers it with the working papers already built.
The T2 behind the plant
The corporate return leans hard on inventory. The year-end count sets closing inventory, closing inventory sets cost of goods, and cost of goods sets taxable income — so shrink, short-dated write-downs and obsolete packaging written off before year-end are deductions only if the count records support them. Inventory is valued at the lower of cost and net realizable value, which matters in a business where product expires on a printed date.
Active manufacturing income up to the $500,000 small business limit is taxed at roughly 12.2% combined in Ontario, and the capital cost allowance schedule on a plant's equipment deserves more attention than a software default gives it — the planning side of that lives with Tax Planning & Advisory. Our Corporate Tax Filing engagements cover the T2, the HST returns and the owners' personal returns together, quoted in writing after a free 15-minute discovery call — no hourly surprises. We prepare them for food producers across Mississauga and the wider GTA.
