General personal-return structure with a 2025 illustration; Quebec and special situations require their applicable forms.
A personal tax return first works out income and allowed deductions, then calculates tax and credits, and finally compares the amount payable with payments and refundable amounts. Your gross salary, taxable income and refund are not interchangeable numbers.
Income, net income and taxable income
Employment is one possible income source. The return brings reportable amounts together and applies deductions according to their rules. Net income and taxable income appear at different stages. Donation limits may use net income while a rate threshold uses taxable income; copying one figure everywhere can be misleading.

Federal and provincial calculations
Federal tax brackets apply to slices of taxable income. Provincial or territorial tax is additional, with its own rates and credits. Quebec administers a separate provincial personal return. Non-refundable credits reduce applicable tax but are not themselves payments already made.

Example: follow the stages, not just salary
Assume $60,000 of employment income and a valid $5,000 deduction, with no other income or deductions. The simplified taxable base becomes $55,000. That does not mean the tax saving is $5,000: the saving depends on the tax applying to the removed income slice.
After rates and credits are applied, suppose the resulting amount payable is $8,000 and payments are $8,500, with no other adjustments. The difference is a $500 overpayment. The $8,000 is an assumed final figure here, not a tax calculation from the $55,000 base.
Where an estimate stops
Beaver Ledger's employment model omits CPP/EI credits and deductions and many personal adjustments. It cannot replace a return for someone with other income, business activity or complex credits. Use it to explore the direction of a change, then use complete records and applicable filing guidance.
- Select the correct tax year.
- Keep income, withholding and claimed deductions separate.
- Review the calculator's exclusions before interpreting a refund.
