CRA Corporate Income Tax Audit — Montreal CPA Firm Near You: Defending Your Corporate Tax Compliance

A CRA Corporate Income Tax Audit involves a detailed review of your company's income tax filings to ensure that all income, expenses, deductions, and tax credits are correctly reported. During a corporate tax audit, CRA will assess your T2 returns and supporting documents to verify that your company has paid the correct amount of taxes and claimed eligible credits without misreporting or underreporting any taxable transactions.
Mackisen CPA Montreal specializes in defending corporate income tax audits by ensuring that all business expenses are properly documented, tax credits are eligible, and income reporting is compliant with Income Tax Act regulations. We provide comprehensive audit defense to minimize tax liabilities and penalties.

Why CRA Conducts Corporate Income Tax Audits
CRA performs corporate income tax audits to verify whether corporations have accurately reported taxable income and claimed eligible deductions. Common reasons for CRA audits include:
• large deductions for business expenses that seem disproportionate to reported income
• inconsistent income reporting between financial statements and tax returns
• misclassified expenses, such as personal or non-business expenses
• incorrect claims for tax credits, including SR&ED credits, investment tax credits, and employee credits
• undocumented or unverified deductions for capital expenditures, overhead costs, or assets
• discrepancies between corporate income and payroll filings, such as T4 slips or RL-1 forms
Learning insight: CRA audits often stem from discrepancies in tax filings or overstated claims. Accurate reporting and clear documentation are essential.
CRA Corporate Income Tax Audit Process
CRA sends an audit letter requesting the T2 corporate return, financial statements, income allocation schedules, and supporting documentation for any deductions or credits.
CRA verifies the accuracy of income reporting and ensures that eligible deductions (e.g., capital expenses, overhead) are properly documented and applied.
CRA examines tax credits and ensures they were claimed according to Income Tax Act provisions (e.g., SR&ED, investment credits).
CRA assesses whether the corporation has correctly classified expenses and taxable income.
CRA requests clarification on intercompany transactions and transfer pricing issues if applicable.
Mackisen CPA prepares a comprehensive defense package, including supporting documentation, clarification of income allocations, and proof of eligibility for any claimed tax credits.
Learning insight: Detailed documentation and clear income allocation will ensure successful defense during a CRA corporate tax audit.
