How the calculator works
- Family net income: yours and your partner’s net income for 2025 (line 23600 of your returns).
- Children: how many are under 6, and how many are 6 to 17.
- Disability: children eligible for the disability tax credit also get the Child Disability Benefit.
How the reduction works
Below $38,237 of family income you get the full amount. Above it, the benefit shrinks by a share of each extra dollar:
| Children | Between $38,237 and $82,847 | Above $82,847 |
|---|---|---|
| 1 | 7% | 3.2% |
| 2 | 13.5% | 5.7% |
| 3 | 19% | 8% |
| 4 or more | 23% | 9.5% |
Provinces and territories pay their own child benefits on top, often with the same payment. See benefits and tax credits.
