Aggressive GST/HST tax schemes in Canada

Most Canadians comply with tax laws, but some individuals and groups use aggressive Goods and Services Tax/Harmonized Sales Tax (GST/HST) schemes to claim unwarranted refunds or reduce their liability to avoid paying the taxes they owe. These schemes are not unique to Canada. They are a global issue and are also common in other tax jurisdictions. Wherever they are found, these aggressive GST/HST schemes undermine the integrity of the tax system and cost the government hundreds of millions of dollars in tax revenue needed for vital programs and services for Canadians.

The Canada Revenue Agency (CRA) collects taxes to support the essential programs and services provided to Canadians by the federal, provincial or territorial, and municipal levels of government, such as education, social services, infrastructure, and public health. Perpetrators of these aggressive GST/HST schemes are committing theft and diminish tax revenue at the expense of all compliant taxpayers.

It is crucial to remain informed and vigilant when it comes to GST/HST schemes, and the risks related to you and your business’s potential participation in them. Individuals or groups involved in these schemes face serious consequences, including penalties, court fines, and even jail time.

How to recognize and avoid involvement in a GST/HST scheme

It is important for every business entering into a GST/HST-related transaction to remain vigilant for indicators of these schemes. You and your business should be aware of warning signs that suggest fraudulent transactions or connections to a larger GST/HST scheme.

Here are some common signs of tax schemes which may help you to recognize suspicious activity and reduce your risk of involvement:

This is not a complete list, and the presence of one or more indicators cannot identify a scheme with certainty. If you come across any of these signs, consider taking a closer look, seeking independent advice, and verifying the legitimacy of the arrangement before going ahead. By staying informed and attentive to these warning signs, you can protect yourself and your business from potential fraud.

Consequences of participating in a GST/HST scheme

In recent years, the CRA has dedicated itself to combating aggressive GST/HST schemes by investing in innovative technology, enhancing business intelligence, and allocating audit resources. The CRA constantly works to identify and address these aggressive schemes and other threats to tax revenue.

You should be aware of scams that entice you into business relationships with promises that easy money can be made by registering for a business number and GST/HST accounts without operating a legitimate business.

Aggressive GST/HST schemes often involve submitting fraudulent claims for GST/HST refunds, which can trigger audits, penalties, and even prosecution. If you authorize someone else to file these claims on your behalf, you (as the business owner) are legally responsible for any debts incurred, including repayment of the full refund amount and the resulting penalties and interest, which can be significant. Participating in such activities equates to fraud and may lead to serious legal consequences, including fines or jail sentences or both.

CRA action against registrants who facilitate or participate in schemes

The CRA is actively pursuing entities involved in these scheme activities, but it is also taking action against those who facilitate and participate in them to ensure equal treatment under the tax system.

The CRA can apply third-party civil penalties against tax preparers, promoters, and other third parties who intentionally file or prepare false statements, or omit information on the tax returns of other individuals or businesses. Third-party penalties are explained in detail in the Information Circular IC01-1, Third-Party Civil Penalties. Third-party civil penalties are serious, and can result in large financial levies.

The CRA will also investigate and prosecute those who promote and counsel others to commit tax evasion. When taxpayers are convicted of tax evasion, they must repay the full amount of taxes owing, plus interest and any civil penalties assessed by the CRA. As well, the courts may fine them up to 200% of the taxes evaded and impose a jail term of up to five years.

The CRA publicly shares cases of individuals, corporations, and trusts convicted of tax evasion. For more information on CRA convictions, go to Enforcement notifications: compliance actions.
