The deadline for most individuals to file their personal income tax returns is April 30th each year. If you or your spouse/common-law partner are self-employed, the deadline is June 15th; however, any taxes owed are still due by April 30th.
Common documents include T4 slips (employment income), T5 slips (investment income), receipts for deductible expenses (e.g., medical, charitable donations), and information on other income sources such as rental or self-employment income. We provide a comprehensive checklist to ensure you gather all necessary documents.
Input tax credits (ITCs) allow you to recover the GST/HST paid on eligible business expenses. For example, if you paid GST/HST on office supplies or business equipment, you may claim ITCs to offset the amount you owe. Our team ensures you maximize these credits to reduce your tax liability.
Corporations can deduct expenses that are directly related to generating business income. Common deductions include salaries, rent, utilities, business travel, and office supplies. Our team will help identify all eligible deductions to reduce your tax burden.
if your business is selected for a CRA audit, it’s important to respond accurately and promptly. We can help you prepare all required documents, communicate with CRA auditors, and ensure the audit is resolved smoothly
