Section 25F Donor Tax Credit Calculator
Estimate the federal credit value of a qualifying SGO contribution based on your filing status and tax situation. Illustrative only — not tax advice.
How the credit works
The Section 25F credit is a non-refundable federal income tax credit — it reduces your federal taxes owed, dollar for dollar, up to the annual maximum.
Unlike a charitable deduction — which reduces your taxable income by your marginal rate — a credit reduces your taxes by the full credited amount, regardless of your bracket.
A donor in a 12% bracket who donates $1,700 to a qualifying SGO receives the same $1,700 credit as a donor in a 37% bracket who donates the same amount.
Annual maximums
Remember
The credit is non-refundable. It can reduce your taxes to zero but cannot generate a refund. If your federal tax liability is less than the credit, the unused portion is not lost — it carries forward for up to five years.
