How Is the Disability Tax Credit Calculated?

The Disability Tax Credit (DTC) is a non-refundable tax credit that reduces the amount of income tax you owe to the federal and provincial governments. It is not a direct cash payment — instead, it lowers your tax bill. If you have paid taxes in previous years, you may be entitled to a retroactive refund for up to 10 years.

The federal DTC base amount for 2025 is $10,138, which translates to a federal tax credit of approximately $1,521 (calculated at the lowest federal tax rate of 15%). For children under 18, an additional supplement of $5,914 is available, adding approximately $887 to the federal credit.

Federal vs. Provincial DTC Amounts

In addition to the federal credit, each province and territory provides its own disability tax credit amount, calculated at the province's lowest marginal tax rate. This means your total annual benefit depends on where you live. For example, Alberta residents receive one of the highest combined credits due to the province's larger base amount, while Ontario residents receive a lower provincial portion.

When you apply for the DTC and are approved, you claim both the federal and provincial amounts on your tax return. If you are claiming retroactively, the amounts for each year may differ slightly due to annual indexation adjustments by CRA.

DTC Credit Amounts by Province (2024/2025 Estimates)

The table below shows the approximate annual DTC credit value for adults (18+) by province, based on publicly available CRA data. These figures represent the actual tax reduction — not the base amount used on your return.

Note: These amounts are approximate and based on the most recently published CRA tax credit rates. Actual amounts may vary slightly due to annual indexation. For children under 18, additional supplements are available at both the federal and provincial level, which can significantly increase the total benefit.

Can You Claim the DTC Retroactively?

Yes. If you have been living with a qualifying condition for multiple years but never applied for the DTC, you can request a retroactive adjustment for up to 10 previous tax years. This means you could receive a lump-sum refund for taxes you overpaid during those years.

The retroactive claim process involves submitting a T1 Adjustment Request for each applicable year. My Benefits Canada handles this entire process — from completing the T2201 form with your medical practitioner to filing the retroactive adjustments with CRA.
