The first-time home buyers' GST rebate pays up to $50,000 on a new home. That headline is accurate and it is on every page that covers the topic. What is usually missing is the set of conditions that decide whether any given buyer actually gets it, and several of them disqualify people who assume they qualify.

This is a summary of published Canada Revenue Agency rules, not tax advice. Confirm your own situation with an accountant before acting on it.

What it pays

100 per cent of the GST, to a maximum of $50,000, on a new home valued up to $1 million. Between $1 million and $1.5 million the rebate reduces on a straight line. At $1.5 million or more it is nothing.

CRA's worked example: a home valued at $1.25 million sits at the mid-point, so it qualifies for 50 per cent of the $50,000 maximum, a rebate of $25,000.

At Alberta price points this phase-out rarely bites. Most new construction in Calgary, and the great majority in Airdrie, Cochrane, Okotoks and Chestermere, sits under $1 million, which is the band where the rebate pays in full.

The condition that catches most people: March 20, 2025

The agreement of purchase and sale must have been entered into on or after March 20, 2025, and before 2031.

This is the single most likely reason an otherwise eligible buyer does not qualify, and it is absent from a lot of the coverage. If you signed with your builder before that date, the rebate is not available to you, however well you meet every other condition.

There is anti-avoidance language attached to it, so restructuring an older deal does not help:

  • The rebate is not available where an agreement entered into before March 20, 2025 is varied, amended or assigned.
  • It is not available where such an agreement is cancelled and a new one signed on or after that date, unless the change can reasonably be considered to have been made for genuine reasons other than obtaining the rebate.

What counts as a first-time buyer here

This programme has its own definition, and it is not the same as the one used by the Home Buyers' Plan or the FHSA. Do not carry an answer across from one to another. To qualify for this rebate you must:

  • be at least 18 years of age
  • be a Canadian citizen or a permanent resident of Canada
  • not have lived in a home, in or outside Canada, that you or your spouse or common-law partner owned as your primary place of residence, at any time in the current calendar year or in the preceding four calendar years

Two things in that last point do real work. The look-back is four calendar years plus the current one, which is longer than people expect. And your spouse's ownership counts against you. If you have never owned a home but you have been living in one your partner owns, this rebate is not available to you.

The other conditions

For a house purchased from a builder, all of the following also have to be true:

  • Construction or substantial renovation begins before 2031 and is substantially completed before 2036.
  • You are a first-time home buyer at the time ownership is transferred to you, not at the time you signed.
  • You are the first individual to occupy the house after construction is substantially completed.
  • You have not received the rebate previously. It is once per lifetime.
  • The home is for use as your primary place of residence.

The rebate is not available to a corporation or a partnership.

Buying with someone else

At least one of the purchasers has to be a first-time buyer who is buying the home as their primary place of residence, and that same person has to be the first individual to occupy it. Where several people own the house, the first-time buyer must be named as the claimant on the application, not merely listed as a co-owner. CRA issues the cheque in the claimant's name only.

That is a filing detail with real consequences, and it is easy to get wrong on a form filled out quickly at closing.

It stacks with the regular rebate

This rebate does not replace the existing GST/HST new housing rebate. CRA describes it as available "in addition to" that rebate, acting as "a top up" to it. Where both apply you claim both. Our fuller piece on the GST rebate on a new home in Alberta covers how the two fit together and why the older rebate often pays nothing at Alberta prices.

A note for Alberta readers on Ontario numbers

Ontario has introduced a provincial first-time home buyers' rebate of up to $80,000 of the provincial part of the HST, which follows the same eligibility conditions as the federal rebate. It does not apply in Alberta, and there is no Alberta equivalent, because Alberta has no provincial sales tax component to rebate.

This matters when you are reading around the topic. Much of what ranks for these searches is written for Ontario buyers and quotes combined totals. An Alberta buyer should read the federal figure as the entire amount available.

Co-operative housing shares

Buying a share in a co-operative housing corporation follows the same conditions on different thresholds: $472,500 raised to $1,575,000. The rebate is not available for a co-op share where the co-op housing is eligible for the purpose-built rental housing rebate.

The short version

Up to $50,000, paid in full below $1 million, which is where most Alberta new builds sit. But you need an agreement signed on or after March 20, 2025, no home ownership by you or your spouse in the current year or the previous four, and you can only ever claim it once. If a builder is crediting the rebate to you at closing, they are required to confirm you meet every condition first, and if it turns out you did not, CRA can come back for the money.

This is a summary of published rules, not tax advice. The conditions here are unusually specific, and the cost of being wrong is the whole rebate, so check your own position with an accountant.
