Subsection 152(7) of the Income Tax Act is the provision that lets the Minister of National Revenue assess your tax payable using the CRA’s own estimate, whether or not you filed a return and whether or not the agency accepts the figures you provided. The statute says the Minister is not bound by any return or information supplied by or on behalf of a taxpayer.1Justice Laws Website. Income Tax Act – Section 152 Once an assessment goes out under this authority, the law treats it as correct until you prove otherwise, and interest starts running from the original filing deadline, not the date on the notice.
What the Provision Actually Does
Two situations trigger 152(7). If you filed a return and the CRA does not believe your numbers, the agency can disregard them and substitute its own. If you never filed at all, the CRA does not have to wait for you. It can construct a tax bill from scratch using whatever data it has.
The operational vehicle for non-filers is the CRA’s Non-Filer Program. Enforcement typically starts with demand letters and escalates through to a 152(7) assessment, with prosecution reserved for a small number of cases.2Canada Revenue Agency. Non-Filer Program Whatever the path in, the result is the same: a legally enforceable debt in the amount the CRA has calculated.
How the CRA Builds Its Estimate
The starting point is third-party information already in the CRA’s hands. T4 slips from employers, T5 slips from banks and brokerages, and T4A slips for contract income give the agency a baseline of reported income even when you have filed nothing.
Where those slips do not capture the whole picture, auditors use indirect methods. The most common is the net worth method. The CRA compares your household assets and liabilities at the start and end of the year, adds back personal spending, subtracts non-taxable receipts, and treats the remaining gap as unreported income.3Canada.ca. Income Tax Audit Manual – Chapter 13 The calculation covers you, a spouse or common-law partner, and dependent children living with you. If you bought a house or a vehicle, or your savings grew in a way your reported income cannot explain, the difference becomes taxable.
The second technique is a bank deposit analysis. When your records are inadequate or unreliable, auditors go through every deposit in your accounts and treat anything they cannot match to a known non-taxable source as income.3Canada.ca. Income Tax Audit Manual – Chapter 13 Gifts, loan proceeds, and transfers between your own accounts are legitimate explanations, but only with documentation. Without paperwork, each unexplained deposit becomes taxable income in the estimate.
For self-employed taxpayers, the CRA also draws on industry benchmarks. If your reported income sits well below typical earnings in your trade, that gap can flag your file and shape the assessment.
Penalties and Interest Piled On Top
The tax estimate is only part of what shows up on the notice. Penalties and compounding interest can easily exceed the underlying tax.
Late Filing Penalty
If you owed tax and missed the filing deadline, the penalty is 5% of the unpaid balance plus 1% for each full month the return is outstanding, up to 12 months. That maxes out at 17% in a single year. If you were penalized for late filing in any of the three previous tax years and the CRA sent you a formal demand to file, the penalty doubles to 10% of the unpaid balance plus 2% per month, running up to 20 months for a potential 50%.4Justice Laws Website. Income Tax Act – Section 162
Gross Negligence Penalty
Where the CRA concludes that you knowingly made a false statement or omission, or did so under circumstances amounting to gross negligence, it can add a penalty equal to 50% of the understated tax.5Justice Laws Website. Income Tax Act – Section 163 The CRA carries the burden of proving gross negligence.6Canada Revenue Agency. Income Tax Audit Manual – Chapter 19 Repeated failure to respond to CRA demands is the kind of conduct that can support such a finding.
Interest
Interest on overdue tax compounds daily. For the second quarter of 2026, the prescribed rate on arrears is 7%.7Canada.ca. Interest Rates for the Second Calendar Quarter The rate resets each quarter. Interest runs from the original filing deadline for the year in question, so an assessment covering several old tax years can arrive with a large interest balance already accrued.
The Burden of Proof Is on You
This is what makes a 152(7) assessment so difficult to shake. The law presumes the Minister’s assessment is correct, and the factual assumptions the CRA relied on when building it stand until you demolish them with evidence.8Canada Revenue Agency. Income Tax Audit Manual – Chapter 28 – Section: 28.4.8 Burden of Proof Do nothing, and the estimate becomes a valid, collectible debt.
In court, you need what lawyers call a prima facie case: enough credible evidence to knock down the CRA’s assumptions on their face. Only once you clear that hurdle does the CRA have to justify its position.8Canada Revenue Agency. Income Tax Audit Manual – Chapter 28 – Section: 28.4.8 Burden of Proof Courts have found that a taxpayer’s unsupported testimony rarely gets there, especially when documents or witnesses that would have helped were never produced. Arguing the CRA’s number feels too high will not work. You need bank statements, invoices, contracts, and ledgers that show what you actually earned.
Fixing or Challenging the Assessment
The first move is almost always to file the return you should have filed. For individuals, that means a T1 General for each year at issue. For corporations, it is the T2 Corporation Income Tax Return.9Canada Revenue Agency. Corporation Income Tax Return A properly supported return gives the CRA a basis to reassess your tax downward.
Assembling that support means pulling bank statements for every account you held in the year, reconciling each deposit to an income source or a documented non-taxable receipt, and separating personal spending from business costs. Sales invoices, payroll records, rent receipts, and vehicle logs matter for self-employed taxpayers. Every figure on the return should trace back to a source document, because auditors will test your numbers the same way they built the estimate. Gaps default back to the higher figure.
One boundary worth flagging: the Voluntary Disclosures Program, which can reduce penalties for taxpayers who come forward before enforcement starts, requires that you apply before the CRA has initiated an audit or investigation on the same information.10Canada Revenue Agency. Voluntary Disclosures Program (VDP) – Who Is Eligible Once a 152(7) assessment has been issued, the non-filer investigation has already been initiated, and VDP is generally no longer available. It is an option for people with unfiled returns who have not yet heard from the CRA, not a remedy after the notice arrives.
Notice of Objection
The formal dispute route starts with a Notice of Objection under section 165. You can file Form T400A or submit through the CRA’s My Account, My Business Account, or Represent a Client portals.11Canada Revenue Agency. T400A Notice of Objection – Income Tax Act If you mail it, use registered mail.
For individuals (other than trusts) and graduated rate estates, the deadline is the later of one year after the filing due date for the year, or 90 days from the date on the notice of assessment.12Canada Revenue Agency. Resolving Your Dispute: Objection Rights Under the Income Tax Act For everyone else, including corporations, the deadline is 90 days from the date the notice was sent.13Justice Laws Website. Income Tax Act – Section 165 Objections to Assessment Miss the deadline and you lose the right to dispute unless you successfully apply for an extension.
Once filed, an appeals officer independent of the original auditor reviews the file. That officer can vacate the assessment, confirm it, or issue a reassessment with adjusted figures. It is your best chance to resolve the matter without going to court.
Appeal to the Tax Court of Canada
If the appeals officer confirms the assessment, or 90 days pass after you filed the objection without a response, you can appeal to the Tax Court of Canada.14Justice Laws Website. Income Tax Act – Section 169 You have 90 days from the date the CRA sends notice confirming the assessment. The burden dynamics carry over: you present your case first, and you have to displace the Minister’s assumptions before the CRA is required to defend them. Turning up without organized financial records is effectively conceding the assessment.
Collection Does Not Wait
A 152(7) assessment creates an enforceable debt the moment it is issued. The CRA has collection tools it can deploy without a court order, and filing an objection does not automatically pause them.
The agency can issue a Requirement to Pay directly to your employer, your bank, or your clients, ordering them to redirect money owed to you to the CRA. Third parties who receive the notice must comply and can be held personally liable if they ignore it. For employees, the CRA can seize up to 50% of net pay. For self-employed workers, it can intercept 100% of payments from clients.
The Minister can also certify the amount owed and register the certificate in Federal Court, which then has the effect of a judgment for that amount plus interest.15Justice Laws Website. Income Tax Act – Section 223 From there the CRA can register liens against real estate, vehicles, or business equipment.
Refunds and credits get pulled in as well. If you are owed a tax refund or receive the GST/HST credit, the CRA can automatically apply it against your debt, and can do the same with corporate refunds against payroll or GST/HST arrears.16Canada.ca. How We Automatically Apply Credits and Refunds to Your Debt Child benefits are one of the few payments excluded from this automatic set-off.
Relief from Penalties and Interest
Where circumstances beyond your control prevented you from filing or paying on time, the CRA has discretionary authority to cancel or waive penalties and interest.17Canada.ca. Cancel or Waive Penalties and Interest at the CRA Relief is not automatic. You apply, and you have to show your situation qualifies. Common grounds are serious illness, natural disaster, CRA processing delays that caused the missed deadline, or financial hardship that made timely payment impossible. Requests can reach back 10 calendar years. Taxpayer relief does not touch the underlying tax; it only addresses the penalties and interest layered on top.
