The likelihood of a Canada Revenue Agency (CRA) audit is generally low for average individual taxpayers, but risk increases significantly with business ownership, high-income, or suspicious deductions. While random audits occur, the CRA primarily targets, using AI, based on risk assessment for errors, non-compliance, or major discrepancies compared to industry standards.
The CRA chooses a file for an audit based on a risk assessment. The assessment looks at a number of factors, such as the likelihood or frequency of errors in tax returns or whether there are indications of non-compliance with tax obligations.
In short, the odds of being audited depends on who you are, where you are, what you do, what types of expenses you have, and so on. Various pieces of a taxpayer's profile may help uncover risk factors. And the more risk factors a taxpayer has, the greater the odds of that taxpayer being audited.
What percentage of tax returns are audited? Your chance is actually very low — this year, 2022, the individual's odds of being audited by the IRS is around 0.4%. However, keep alert for the IRS audit triggers. Are you a high income earner?
Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit. The IRS mostly audits tax returns of those earning more than $200,000 and corporations with more than $10 million in assets.
What happens during an audit? Internal audit conducts assurance audits through a five-phase process which includes selection, planning, conducting fieldwork, reporting results, and following up on corrective action plans.
The four key components of audit risk, as defined by the Audit Risk Model, are Inherent Risk, Control Risk, Detection Risk, and Acceptable Audit Risk (or Overall Audit Risk), representing the susceptibility of accounts to misstatement, failures in internal controls, the auditor's chance of missing errors, and the acceptable level of risk for the audit, respectively, all combining to determine if a materially misstated financial statement receives an inappropriate opinion.
Audit rates are generally highest for high-income taxpayers, taxpayers with business income, large corporations, and earned income tax credit claimants. In its annual data books, the IRS presents audit rates for tax returns filed for each year over the previous decade.
Discrepancies between tax returns and bank statements
One of the most significant red flags for CRA auditors is the mismatch between reported income on tax returns and actual bank deposits. This discrepancy often indicates unreported income, which can trigger an immediate audit.
Canada's 90% rule helps non-residents and recent immigrants claim full federal tax credits (like the Basic Personal Amount) if 90% or more of their net worldwide income for the relevant tax year is from Canadian sources; otherwise, credits are prorated (reduced) based on their Canadian residency period, ensuring fairness for those who weren't residents all year.
Business- Section 44AB(a)
A business is required to get an income tax audit if its total sales/turnover/gross receipts exceed ₹1 crore in a financial year. However, the limit for tax audit has been relaxed to ₹10 crore if: Cash receipts ≤ 5% of total receipts, and. Cash payments ≤ 5% of total payments.
After your tax return is processed, you'll receive a notice of assessment. Your tax return could be selected for review before or after you receive your notice. A tax audit may be triggered if the CRA is not satisfied with your review, or if they suspect fraud or non-compliance.
The IRS usually reviews receipts during an audit — if you don't have the receipts, you can sometimes use bank statements or credit card statements to prove your claims instead. Consequences of being audited without receipts can include additional taxes, interest, and financial penalties.
It's good to be specific, but there's a danger in words such as “everything,” “nothing,” “never,” or “always.” “You always” and “you never” can be fighting words that can distract readers into looking for exceptions to the rule rather than examining the real issue.
To avoid the 22% tax bracket (or any higher bracket), focus on reducing your taxable income through strategies like maxing out 401(k)s and HSAs, deferring bonuses, tax-loss harvesting, smart charitable giving, and strategic asset location, understanding that higher rates only apply to income within that bracket, not your entire income.
The "20k rule" refers to the traditional IRS threshold for reporting income from payment apps and online marketplaces on Form 1099-K: over $20,000 in gross payments AND more than 200 transactions in a calendar year. While a law (the American Rescue Plan) temporarily lowered the threshold to $600, recent legislation, the One Big Beautiful Bill Act (OBBBA) (OBBBA), has reinstated the $20,000/200-transaction rule for tax years starting in 2025, providing relief for casual sellers and gig workers.
If the deductions, losses, or credits on your return are disproportionately large compared with your income, the IRS may want to take a second look at your return. Taking a big loss from the sale of rental property or other investments can also spike the IRS's curiosity.
The 5 Cs of audit (Criteria, Condition, Cause, Consequence, Corrective Action) are a framework for structuring clear, actionable audit findings, explaining what should be (Criteria), what is found (Condition), why it happened (Cause), what the impact is (Consequence/Effect), and how to fix it (Corrective Action/Recommendation) to drive organizational improvement and compliance.
The IRS escalates its collection efforts when the amount owed exceeds $25,000, which can result in severe penalties such as asset seizure, bank levy, wage garnishment, and even passport revocation. If you're unsure how much you owe, you can find more information and guidance here.
There are five potential threats to auditor independence: self-interest, self-review, advocacy, familiarity, and intimidation. Any lack of independence compromises the integrity of financial markets.
A financial audit is one of the most common types of audit. Most types of financial audits are external. During a financial audit, the auditor analyzes the fairness and accuracy of a business's financial statements. Auditors review transactions, procedures, and balances to conduct a financial audit.
Overall audit risk does not include the risk of the auditor erroneously concluding that the financial statements are materially misstated.
