What Taxes Apply If You Assign a Presale Contract in BC?
Assignment profit isn't treated like a normal capital gain. Here's the three different taxes that can apply to the same sale, and why the tax bill can end up larger than sellers expect.
“• Up to three separate taxes can apply to presale assignment profit: GST on the assignment premium, BC’s home flipping tax, and federal income tax.
• These aren’t alternatives to choose between, more than one can apply to the same assignment sale.
• CRA generally treats assignment profit as fully taxable business income, not a capital gain, which means the full amount is taxed rather than just half.
• Get real numbers from an accountant before you assign, the tax picture here is genuinely more complex than a standard property resale.”
Assignment Profit Gets Taxed Differently Than You'd Expect
If you're thinking about assigning a presale contract for a profit, it's worth understanding upfront that the tax treatment is meaningfully different from selling a completed, titled property, and the difference tends to work against the seller, not in their favour, compared to what a lot of people assume going in.
The three taxes that can apply
There are potentially three separate taxes in play, and they're not alternatives where only one applies, more than one can hit the same transaction:
GST can apply to the assignment premium, the profit portion of the sale, since CRA treats an assignment sale as a supply subject to GST in many circumstances.
BC's home flipping tax can apply if you've held the presale contract for less than 730 days (two years) before assigning it, a provincial tax specifically aimed at short-term property flipping, presale contracts included.
Federal income tax applies to the profit itself, and this is where the treatment diverges most sharply from a typical property sale: CRA generally treats assignment profit as fully taxable business income rather than a capital gain, which means the entire profit amount is taxable, not just half, as would be the case with a capital gain on a normal resale.
Why the combination catches people off guard
A straightforward property resale, held as a capital asset, only has half the gain taxed federally, plus BC's separate flipping tax rules if it applies. An assignment profit can face GST, the flipping tax, and fully taxable income treatment all in the same transaction, which adds up to a meaningfully larger tax bill on the same dollar amount of profit than most sellers expect based on how property sales are typically taxed.
Get real numbers before you set a price
This isn't a reason to avoid assignment if it's the right move for your situation, but it is a strong reason to get real numbers from an accountant who understands presale assignment specifically, before you finalize a price or count on a certain net amount from the sale. The gap between gross profit and what actually lands in your pocket after these taxes can be significant, and it's much better to know that going into the negotiation than to discover it afterward.
What This Means for You
If you're weighing an assignment sale, I'd get a real accountant's read on your specific tax exposure before you set a price, because the number you're picturing and the number you'll actually net can be quite different once GST, the flipping tax, and full income tax treatment are all factored in. It's a conversation worth having early, not after you've already agreed to a price with a buyer.
Your Next Step.
Assignment taxation in BC is genuinely more complex than a standard resale, but understanding it upfront means no unpleasant surprises later. If you're considering assigning a presale contract and want help thinking through the numbers, send me a message and I can also point you toward an accountant who specializes in this.
