Couples and single parents supporting a dependent
- Spousal and Equivalent-to-Spouse credits: Set to match the new Basic Personal Amount. These credits are reduced as your spouse’s or dependent’s income rises. They remain non‑refundable (they only reduce tax you owe; they don’t create a refund).
People with disabilities and their families
- Disability Tax Credit supplement for children under 18: Uses fixed 2026 dollar amounts and is indexed from 2027 onward. The maximum provincial supplement in 2026 is about $1,500, reduced if certain care expenses are claimed. Non‑refundable.
Volunteer first responders
- If you complete at least 200 hours of eligible service in a year, the base for your credit doubles to $6,000 starting in 2026. That cuts your provincial tax by up to about $630 (non‑refundable).
Businesses (fertilizer projects)
- Large chemical fertilizer projects get more time to meet the $10 million investment minimum (until December 31, 2031) and clearer program rules. Companies must apply for rebates within three years of the taxation year, submit financial statements, and keep records. No rebates after 2044.
