Schedule 1 (T2)
Also known as: T2 Schedule 1
Schedule 1 reconciles a corporation's accounting net income to its net income for tax purposes by adding back and deducting specific items.
Accounting profit and taxable profit are rarely the same number. Schedule 1 starts from net income per the financial statements, then adds back non-deductible items (like accounting depreciation) and subtracts tax-only deductions (like CCA) to reach net income for tax.
It's the bridge between the books and the tax return, and it explains why the tax you owe doesn't simply equal your accounting profit times a rate.
How Comma handles it
Comma builds Schedule 1 from your posted ledger, adding back book depreciation and applying CCA so the book-to-tax reconciliation is done for you.
