Penalties and Compliance Risks
Staying on top of your underused housing tax obligations is more than just good practice, it’s essential for avoiding costly penalties. The Canada Revenue Agency takes compliance seriously, and even small mistakes can lead to large fines.
Why Compliance Matters
Filing the underused housing tax late or not at all can result in serious consequences. These penalties apply whether or not you owe any tax, which makes timely filing crucial. In addition to the base fines, interest charges can accumulate, increasing the financial burden.
Avoiding Mistakes
The underused housing tax rules are complex, and many owners mistakenly assume they do not need to file. For example, some property owners believe that being exempt from the tax means no return is required, but that’s not the case, filing is still mandatory. These errors can flag your account for review and create long-term issues with the CRA.
