Consignment and thrift store tax: revenue, HST, and the agency question

Your taxable revenue may be the commission, not the sticker price

When you sell a consignor's item as their agent, the money that changes hands at the register was never entirely yours — the consignor's share is their income, not yours, and your T2125 or corporate T2 should generally report only the commission you retained as revenue. Reporting the full ticket price as gross sales and the consignor's cut as an expense can arrive at the same bottom-line profit, but it inflates your gross revenue figure, which matters for GST/HST registration thresholds, loan applications, and how a lender or buyer reads your financials.

The correct treatment turns on how your consignment agreements are actually written and administered, not on habit. A handshake understanding is not the same as a document that clearly establishes an agency relationship, and it is worth confirming your paperwork actually supports the tax position you are using before you build years of filings on top of it.

HST outcomes differ across three models that can sit in the same store

A registered charity selling donated goods, a for-profit shop selling on consignment, and a shop buying used goods outright to resell can owe genuinely different GST/HST on what looks like an identical transaction to the customer at the till.

Being used does not by itself reduce or remove GST/HST — that is one of the most common misconceptions we hear from new consignment and thrift operators. Outside the specific charity exemption for donated goods, a sale is taxed the same whether the item is new or secondhand, and there is generally no notional input tax credit available to a consignment shop that never actually purchased the goods it is selling.

There is no cost-of-goods deduction for items you never bought

A genuine consignment sale has no purchase invoice behind it, which means there is no cost of goods sold to deduct against that sale — your deduction chain runs through the commission you earned, plus the ordinary running costs of the shop. Paying out the consignor's share when an item sells is settling a liability already recorded on your books, not buying inventory, and it should never be coded as a purchase expense. This distinction is exactly why the bookkeeping structure on our bookkeeping page has to be right before the tax return is prepared — the return is largely a transcription of correctly coded books, not a place to reclassify a year of transactions after the fact.

Consignment characterization draws real scrutiny — document it properly

Because the agency relationship changes both revenue recognition and GST/HST treatment so significantly, it is an area where documentation matters more than most small business owners expect. A signed consignment agreement per supplier, a consistent commission structure, and records showing the consignor retained ownership until sale are what support the tax position if it is ever reviewed. Businesses that treat consignment as an informal arrangement — no agreement, inconsistent splits, cash paid out without a paper trail — are the ones most likely to have that characterization challenged, with the full sale price reassessed as taxable revenue after the fact.

Whether you run a single storefront or list overflow inventory on US marketplaces, getting the underlying revenue and HST treatment right is the foundation everything else sits on. There is also no professional corporation option to weigh here either way — resale retail is not a regulated profession, so once you decide to incorporate, an ordinary business corporation is the only structure on the table, and the decision comes down to timing and retained profit rather than a special designation. Our tax services are built around how your specific model actually operates, not a generic retail template.
