First-Time Home Buyer Tax Credits and Incentives – A Complete Guide by a Montreal CPA Firm Near You

Buying your first home is one of the biggest financial steps you will ever take, and

understanding the first-time home buyer tax credit in Canada is essential for reducing

costs and maximizing available incentives. Many first-time buyers are unaware of the

tax credits, rebates, and government programs that can significantly reduce the financial

burden of purchasing a home. The First-Time Home Buyers’ Tax Credit (HBTC), the

GST/HST New Housing Rebate, and various provincial incentives can provide

thousands of dollars in tax relief. However, each credit has strict eligibility rules,

documentation requirements, and timing considerations. Failing to apply correctly or

misunderstanding the rules can result in lost benefits. This guide explains the first-time

home buyer tax credit in Canada, the GST/HST rebate, and other incentives available to

help first-time buyers save money and avoid costly mistakes.

Legal and Regulatory Framework

The First-Time Home Buyers’ Tax Credit is governed by section 118.05 of the Income

Tax Act. Eligible first-time buyers can claim a non-refundable tax credit based on a fixed

amount multiplied by the lowest personal tax rate. To qualify, the buyer must not have

owned and lived in another home in the current or preceding four years unless

purchasing for the benefit of a disabled relative. The GST/HST New Housing Rebate is

governed by section 256.2 of the Excise Tax Act, which permits eligible individuals to

recover a portion of the GST or federal component of HST paid on newly built homes,

substantially renovated homes, or homes purchased from builders. Provincial rebates

vary by province but generally follow similar rules. Buyers must also meet mortgage

qualifications and legal residency requirements. These laws form the foundation of tax

incentives available to first-time home buyers in Canada.

Key Court Decisions

Court rulings highlight how strictly the first-time home buyer tax credit and rebates are

interpreted. In Chan v. Canada, CRA denied the HBTC claim because the taxpayer had

joint ownership in another property within the previous four years, even though they

never lived in it; the court upheld CRA’s decision. In Gibson v. The Queen, CRA denied

the GST/HST New Housing Rebate because the home was not intended as the primary

place of residence, reinforcing that rebate eligibility requires genuine occupancy. In Koo

v. Canada, the Federal Court confirmed that substantial renovations must meet CRA’s

definition of “gutting the home to the studs” to qualify for a rebate. These cases

emphasize the importance of understanding eligibility rules before claiming first-time

buyer credits and rebates.

Why CRA Targets This Issue

CRA scrutinizes first-time buyer claims because of frequent misunderstandings and the

significant tax savings involved. Many taxpayers incorrectly assume they qualify as first-

time buyers despite having previously owned property, having lived with a spouse who

owned property, or purchasing investment properties. CRA also reviews GST/HST

rebate claims closely because rebate amounts can be substantial, especially for new

builds and pre-construction homes. CRA examines whether the property is truly used as

a principal residence, whether the purchase price qualifies, and whether occupancy

rules were met. Errors in filing rebate forms or failure to provide documentation often

result in denied claims. Because the first-time home buyer tax credit in Canada and

related rebates can provide thousands of dollars in relief, CRA targets these claims to

ensure compliance.

Mackisen Strategy

At Mackisen CPA Montreal, we help first-time buyers determine eligibility and ensure all

tax credits and rebates are claimed correctly. Our process starts with an analysis of

property ownership history, residency status, marital status, and intended use of the

home. We verify whether clients meet the four-year rule for the HBTC and whether any

exceptions apply, such as purchasing for a disabled family member. For the GST/HST

New Housing Rebate, we review builder contracts, closing documents, and occupancy

requirements. We complete all necessary rebate forms, ensuring accuracy and

compliance with CRA guidelines. For clients purchasing pre-construction homes, we

analyze the builder’s adjustments and determine whether federal and provincial rebates

apply. Our strategic approach ensures first-time buyers maximize every available tax

benefit while avoiding errors or CRA disputes.

Real Client Experience

A first-time buyer came to us after CRA denied their HBTC claim because they

previously owned a property jointly with a sibling but never lived there. We reviewed the

ownership structure and demonstrated that the client did not ordinarily inhabit the

property, which allowed us to successfully reinstate the credit. In another case, a couple

purchased a newly built home but misplaced key documents needed for the GST/HST

rebate. We reconstructed the paperwork, obtained missing builder statements, and

secured the rebate. A third client purchased a pre-construction condo and was unsure

whether the unit qualified as a principal residence. We analyzed occupancy plans,

reviewed closing documents, and ensured compliance with rebate rules. These cases

illustrate how first-time home buyers benefit from professional support when navigating

tax incentives.

Common Questions

Many first-time buyers ask whether they qualify if they previously owned a home but did

not live in it. Under certain circumstances, they may still qualify. Others ask whether

buying with a spouse affects eligibility. If either spouse owned a home in the past four

years, neither may qualify unless the purchase is for a disabled relative. Buyers also

ask whether renovation costs qualify for rebates. Only substantial renovations that meet

CRA’s definition may qualify. Another question concerns pre-construction homes: most

qualify for the GST/HST rebate if occupancy rules are met. These questions highlight

the importance of understanding the detailed rules surrounding the first-time home

buyer tax credit in Canada.
