HST on an assignment sale.

Assignors used to argue about whether their assignment was taxable. Since 7 May 2022 there is nothing to argue about — every assignment of newly built residential housing is a taxable supply.

Quick answer: HST at 13% applies to your profit on an assignment sale — and to your entire assignment price, deposit included, if the agreement does not separately identify the deposit reimbursement. That one drafting detail is usually a five-figure difference. Enter your numbers below to see it.

№ v.1Estimate Your HST

HST on your assignment, estimated

Enter your original purchase price and the price the assignee is paying you. Flag whether the agreement separates out your deposit reimbursement.

Assignments often carry interim occupancy too. See the interim occupancy fee calculator → if the unit hasn't registered yet.

№ v.2The Basics

What the tax applies to

Intention no longer matters — only the numbers do.

HST applies to the assignment amount — in practice, your profit. Intention no longer matters: it is taxable whether you bought to flip or bought to live in it and had your circumstances change.

The deposit reimbursement is the part people get wrong. If your assignment agreement separately identifies the amount that reimburses your deposit, that portion is excluded. If it does not, the CRA can treat the whole consideration as taxable — which is the difference the switch in the calculator above shows, and it is usually five figures.

№ v.3Two Different Problems

Who remits, and what else is waiting

The assignor's problem, and a separate income-tax question.

The assignor is normally the one required to collect and remit the HST, and may need to register for a GST/HST number to do it. Assignees regularly discover at closing that the tax was never collected and the builder is looking to them.

Separately, the CRA generally treats assignment profit as business income rather than a capital gain, so the whole profit is taxable rather than a portion of it. Two different taxes, two different problems, and the agreement wording drives both — see HST on Condo Assignment Sales → for the full picture.

№ v.4Worked Example

A $700,000 → $820,000 assignment, deposit wording compared

Say your original agreement was $700,000 and your assignee is paying $820,000. Here is the same deal with the deposit reimbursement worded two different ways:

Your profit on the assignment$120,000.00

Agreement separates out the deposit reimbursement:

Amount HST applies to$120,000.00
HST at 13%$15,600.00
Profit after HST$104,400.00

Agreement does NOT separate it out:

Amount HST applies to (the whole assignment price)$820,000.00
HST at 13%$106,600.00
Profit after HST$13,400.00

One clause is the difference between keeping $104,400 and keeping $13,400 of the same deal. Run your own numbers in the calculator above.

№ v.kKnow the Words

Key terms

Assignment saleSelling your rights under an agreement of purchase and sale before the original closing — typically before a pre-construction unit is built.
Assignment fee / profitThe amount the assignee pays you above what you originally agreed to pay the builder; this is what HST applies to at minimum.
Deposit reimbursementThe portion of the assignment price that repays your original deposit — excluded from HST only if the agreement separately identifies it.
Assignor / assigneeThe assignor is the original buyer selling their contract rights; the assignee is the new buyer stepping into that contract.
№ v.6Before You Ask

Common questions

Is HST payable on an assignment sale in Ontario?

Yes. Since 7 May 2022 every assignment of newly constructed or substantially renovated residential housing is a taxable supply, regardless of the assignor's original intention.

Is HST charged on the deposit I get back?

Only if the assignment agreement fails to separate it out. Where the agreement expressly identifies the portion that reimburses the deposit, that portion is excluded from the taxable consideration. Where it does not, the entire amount can be taxed.

Who has to remit the HST on an assignment?

Normally the assignor, who may have to register for a GST/HST account in order to do so.

Is my assignment profit a capital gain?

Usually not. The CRA generally treats assignment profit as business income, which means the full amount is taxable rather than only a portion of it.
