Commitment to Service Excellence

The Ministry of Finance is committed to providing high-quality, accessible services in tax and benefits administration for all Ontarians.

Our goal is to be recognized by our customers as a highly professional organization that keeps pace with the rising expectations of Ontarians for high-quality and cost-effective public services – while promoting predictability and transparency throughout the delivery process.

We will continue to identify areas for improvement in our service delivery process by looking for ways to create faster and more streamlined services.

Service standards are our commitment to provide a level of service that a customer can expect and a means to monitor our performance results. Results are publically reported annually.

Our Commitment to You

We strive to provide the following:

  • Quick and respectful service using clear language in our written and verbal communications.
  • Services available in both official languages, of equal quality and accessibility.
  • Unbiased and accurate information.
  • Applications and information requests processed in a timely manner.
  • Private and confidential treatment of your information.
  • A clear explanation of your file and how you can review or appeal our decisions.
  • Opportunities to voluntarily disclose your tax information.

Service Standards


We are responsible for collecting the revenue payable under the law so that the government is able to fund the programs and services that are a priority for the people of Ontario. Tax laws require taxpayers to meet their tax obligation and to pay their fair share.

If you fail to pay or remit your provincial taxes or penalties and interest in a timely manner and your account remains delinquent after notification, progressive collection action will be initiated. This could include garnishments and liens, and other methods of collecting. 

Once payments for all taxes, interest and penalties have been received, we will:

  • Release garnishments, warrants and discharge liens within 20 calendar days.


If you do not agree with an assessment, a refund disallowance, a determination of eligibility or an entitlement decision issued by the ministry you may have discussions with the appropriate ministry office to resolve issues about tax and program decisions. The letter or form you received from the ministry will include contact information.

If discussions do not resolve your issue, you have the right to file a Notice of Objection.

You can file a Notice of Objection online, or obtain a Notice of Objection form from the Ministry of Finance website or any ServiceOntario office.

Once a Notice of Objection has been filed, the ministry will conduct a timely, independent review of your objection, considering your reasons for disagreement and will:

  • Acknowledge receipt of Notice of Objection within 5 working days.
  • Resolve objections dealing with interest and penalties within 2 months from date of receipt.
  • Resolve objections not dealing with interest and penalties within 18 months from date of receipt. 

Account Administration
