About the Ministry

The Ministry of Revenue administers the province's major tax statutes, tax credit and benefit programs. The tax revenues collected provide the fiscal foundation upon which many of the province's programs are based.

The ministry:

• operates a fair, effective, cost-efficient and confidential tax system which minimizes the regulatory and administrative burden to individuals and businesses;
• maintains the integrity of the province's self-assessment system by encouraging voluntary compliance through taxpayer education and independent objections review, and carrying out collection activities, audit and investigations;
• supports the implementation of a single corporate tax collection system together with the federal government.
