Frequently Asked Questions
What is the small business deduction in Ontario?
The small business deduction (SBD) allows Canadian-Controlled Private Corporations (CCPCs) to pay a reduced tax rate of 12.2% on the first $500,000 of active business income. This includes 9% federal tax and 3.2% Ontario provincial tax. Businesses in Mississauga, Toronto, and across the GTA benefit significantly from this preferential rate.
What is the general corporate tax rate in Ontario for 2026?
For income above $500,000, the general corporate tax rate in Ontario is 26.5% combined (15% federal + 11.5% provincial). This applies to CCPCs and non-CCPCs for active business income that exceeds the small business limit. Ontario corporations should engage a CPA to optimize tax planning strategies.
How is Manufacturing & Processing (M&P) income taxed differently?
M&P income over $500,000 qualifies for a reduced provincial rate of 10% (vs. 11.5% general), resulting in a 25% combined rate instead of 26.5%. This 1.5% savings can significantly benefit manufacturing businesses in the GTA and across Ontario. Proper documentation and CPA guidance are essential to claim M&P credits.
When is the T2 corporate tax return due in Canada?
T2 corporate tax returns are due six months after your fiscal year-end. However, any taxes owing must be paid within two (or three months for CCPCs eligible for SBD) after the fiscal year-end to avoid interest and penalties. Mississauga and Toronto businesses often work with CPAs to ensure timely filing and tax optimization.
Can I reduce my corporate tax bill in Ontario?
Yes. Strategic tax planning can include: maximizing the small business deduction, claiming SR&ED credits, utilizing capital cost allowance (CCA), optimizing salary vs. dividend strategies, and leveraging Ontario tax credits. A CPA in Mississauga or the GTA can help identify legitimate deductions and credits specific to your business.
