Interest and Penalty Relief Period Ends October 1, 2025
In April 2025, the Ontario government introduced six months of interest and penalty relief for businesses to temporarily delay payments for select provincial taxes. This relief period ends on October 1, 2025.
To avoid interest and penalties, Ontario businesses must pay any outstanding taxes from April 1 to October 1, 2025, by October 1, 2025.
If you need to make a payment, please use ONT-TAXS online or contact the Ministry of Finance at 1-866-668-8297.
