How the DTC Calculator Works

The Disability Tax Credit (DTC) is a non-refundable federal tax credit worth approximately $1,470 per year. Most provinces add a further $440–$640 per year. If you have been eligible for multiple years, you can claim retroactively for up to 10 years — resulting in a lump-sum refund.

Select your province, the number of years you have been eligible, whether you are claiming for yourself or a child, and your household income. The calculator applies the federal credit, your provincial credit, any child supplement, and an income-based adjustment to produce an estimated range.

Federal and Provincial DTC Credit Amounts

Federal credit per year: approximately $1,470. Provincial credits vary: Ontario $530/yr, Alberta $560/yr, BC $500/yr, Quebec $640/yr, Manitoba $490/yr, Nova Scotia $510/yr, New Brunswick $480/yr, Newfoundland $520/yr, PEI $440/yr, Saskatchewan $500/yr.

Child supplement (if claiming for a child): approximately $850/yr additional federal credit. Low-income households (under $35,000) may receive a higher effective benefit.

How Much Can I Receive?

A typical applicant eligible for 7 years in Ontario with moderate income can expect an estimated retroactive refund of $12,000–$18,000. Families with children may receive additional Child Disability Benefit payments of up to $3,411/year tax-free.
