Non-Taxable Amounts still Reported on Income Tax Returns
There are certain amounts that must be included in income, and then deducted from income on ones tax returns. This is done to reduce or eliminate some benefits the taxpayer would receive had the amount not been included in income, and then removed as a deduction.
The following would be reported on Line 147 (other payments)
- Worker’s compensation benefits (T5007 slip);
- Social assistance payments; and
- Net federal supplements from T4A (OAS) slip.
Line 250 deducts the above from Line 147. This means it is included on Line 234 which is net income before adjustments. Line 234 is used to calculate the working income tax benefit, the medical expense tax credit, and many more.
