Tax interest rates

Description

Tax interest is compounded daily and interest rates are reset every 3 months. **Note:** Provincial land tax interest rates are not reset every three months. Provincial land tax interest rates are summarized on the [provincial land tax webpage](https://www.fin.gov.on.ca/en/consultations/landtaxreform/payment-forms.html). Interest rates do not apply to the Estate Administration Tax Act, 1998. Current interest rates (January 1, 2025 to March 31, 2025): * 9% on taxes you owe to the ministry * 3% on taxes you overpaid * 6% on taxes or refunds you are eligible for as a result of a successful appeal or objection * 6% on late International Fuel Tax Agreement payments * 6% on International Fuel Tax Agreement refunds the ministry has not paid you within 90 days You can download the dataset to view the historical tax interest rates. __Non-Resident Speculation Tax (NRST)__ _(1)_ Interest on tax you overpaid begins to accrue 40 business days after a complete NRST rebate or refund application is received by the Ministry of Finance to the date the rebate or refund is paid. _(2)_ On refunds you are eligible for as a result of a successful appeal or objection of a NRST refund/rebate disallowance, the interest rate is the same rate as though you had overpaid and will begin to accrue 40 business days after a complete NRST rebate or refund application is received by the Ministry of Finance to the date the rebate or refund is paid. Refunds as a result of a successful appeal or objection of NRST that was paid pursuant to a Notice of Assessment, interest will accrue at the higher appeals/objection rate, beginning to accrue from the date of payment to the date the rebate or refund is paid.
