CRA reviews are won on documentation: every figure filed should trace to a source document, and deadlines — 90 days for an objection — are unforgiving. The Voluntary Disclosures Program can waive gross-negligence penalties and part of the interest — but only while the CRA has not yet contacted you. We quote notice of reassessment review as one cheap fixed price — the budget-friendly alternative to hourly billing.
Most write-ups of notice of reassessment review describe the form. These notes describe the file — what a tax practitioner checks first and why.
One rule does more work than the rest combined, so it goes first. Taxpayer relief applications can cancel penalties and interest arising from CRA delay, serious illness or a natural disaster. The CRA is limited to the ten prior calendar years.
Once that is settled, the next question answers itself less often than clients expect. The normal reassessment period runs three years from the original notice of assessment for an individual or a CCPC and four years for other corporations. A waiver signed at an auditor’s request removes that limit for the issue it describes. It stays open until it is revoked. The documentation side matters just as much. Once the CRA confirms an assessment or reassesses following an objection, the next step is an appeal to the Tax Court of Canada within 90 days. An extension has to be applied for rather than assumed, and the merits of the position do not extend the deadline.
What this means for you depends entirely on facts we have not seen yet — which is the honest answer, and the reason a tax practitioner starts every notice of reassessment review engagement with questions rather than conclusions. What you bring to the table determines how quickly the notice of reassessment review work proceeds — start with the items below.
The last note is about how we work rather than the rules: every engagement comes with a fixed fee agreed up front, a review with you before filing, and payment after — not before — the service.

The ledger at a business owner considering a voluntary disclosure in Lethbridge, Alberta could not support its own filings. The reason was a waiver signed at the counter that kept an otherwise closed year open with no end date. Rebuilding it surfaced $18,000 in unclaimed input tax.
A business owner considering a voluntary disclosure in Lethbridge, Alberta could not answer basic questions about its own numbers. A waiver signed at the counter that kept an otherwise closed year open with no end date sat between the bank statements and the ledger. We kept the waiver narrowed to the issue actually under review and let the remaining years close on the normal reassessment period. We then documented the process so the work does not depend on any one person remembering how it was done. Records rebuilt and reconciled, $18,000 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.
A $110,000 reassessment was proposed against a shareholder assessed on a taxable benefit in Guelph, Ontario. It followed a proposal letter with a 30-day response window and no supporting records assembled. The documented response reduced it to nil.
A review notice arrived at a shareholder assessed on a taxable benefit in Guelph, Ontario, covering notice of reassessment review for two tax years. The auditor's working position was an adjustment of $110,000. It was driven by a proposal letter with a 30-day response window and no supporting records assembled. Rather than negotiate, we rebuilt the record. We traced each unexplained deposit to its source — loans, transfers between accounts, an insurance settlement — and reduced the net-worth assessment accordingly. We then submitted a point-by-point response that answered each proposed adjustment with the document behind it. The auditor accepted the documented position and closed the review without adjustment, protecting $110,000 and leaving the prior filings undisturbed.
The structure at a taxpayer applying for relief from penalties and interest in Kelowna, British Columbia no longer fitted the business. A director liability assessment for a corporation that had already stopped operating showed it. Rebuilding it saves $24,000 a year.
The structure at a taxpayer applying for relief from penalties and interest in Kelowna, British Columbia dated from years earlier. It had been set up for a business that no longer existed. A director liability assessment for a corporation that had already stopped operating had become expensive. We requested the auditor’s working papers and report to see how the assessment had been built before answering any of it. The reorganisation used the rollover provisions rather than a taxable transfer, so no tax fell due on the restructuring itself. $24,000 of annual saving, achieved on a tax-deferred basis. The minute book, elections and valuations are all in the file.
A restaurant under a net-worth audit in Barrie, Ontario was profitable and permanently short of cash. Behind the gap sat an audit conducted over the phone, with nothing on file showing what had been provided or when. Restructuring the tax cycle freed $80,000.
A restaurant under a net-worth audit in Barrie, Ontario was profitable on paper and short of cash every month. An audit conducted over the phone, with nothing on file showing what had been provided or when explained most of the gap. We answered each query in writing with an indexed document package, so the file showed exactly what the auditor had received and on what date. We also built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars. $80,000 was released back into working capital. Remittances have been on time every period since, and the forecast shows the tax outflow before it lands.
A contractor facing a proposed reassessment in Moncton, New Brunswick had never tested its work against the eligibility rules. The resulting $100,000 claim was accepted without adjustment.
A contractor facing a proposed reassessment in Moncton, New Brunswick assumed the credits did not apply to a business its size. A waiver signed at the counter that kept an otherwise closed year open with no end date meant they had applied all along. We identified the qualifying activity and built the documentation to support it. Then we brought every outstanding return current, then negotiated a payment arrangement that stopped the collections action. $100,000 recovered. Because the eligibility analysis is on file, the same claim can be repeated each year with a fraction of the effort.
A desk review assessed a taxpayer with eight years of unfiled returns in Windsor, Ontario $37,500. The dispute was over an objection deadline that had passed with no extension applied for. Producing the records vacated the assessment.
A taxpayer with eight years of unfiled returns in Windsor, Ontario was carrying $37,500 of penalties and interest. The charges arose from an objection deadline that had passed with no extension applied for. Much of that amount accumulated during a period the CRA itself had delayed. We filed the Tax Court appeal inside the window and resolved the remaining adjustments before a hearing date was needed. We framed the relief application on the specific grounds the CRA guidelines recognise rather than on general hardship. The assessment was vacated. $37,500 came off the account, and the documentation now on file makes the same position straightforward to defend next time.

Direct answers to what Canadian business owners actually ask before hiring an accountant.
Notice of Reassessment Review starts at a fixed fee quoted before any work begins. The quote is locked at the outset and does not change mid-engagement, and you pay only after you have reviewed and approved the deliverable. Compare every plan on our transparent pricing page.
At minimum: prior-year returns and notices of assessment, your bank and credit-card statements for the fiscal period, payroll records if you have employees, and GST/HST filings. We send a checklist tailored to your situation after the free 15-minute call.
Most engagements are completed within 3 to 5 business days once your documents are complete. Catch-up work covering multiple years takes longer, and we tell you the realistic timeline before you commit rather than after.
We respond on your behalf at no extra charge for any return we prepared. Every figure we file is supported by documentation retained in your file, which is what turns a CRA review from a crisis into correspondence. See how our CRA audit representation works.
Yes. Late filing penalties compound at 5% of the balance owing plus 1% per month, so the cost of waiting is real. We prioritise catch-up work and, where eligible, file under the CRA's Voluntary Disclosures Program to reduce penalties.
Yes. We serve clients in every province and territory at the same fixed fees, so your location does not change the price or the service. Browse our coverage across Canada to find your city.
We work across construction, healthcare, e-commerce, professional services, restaurants, real estate, transportation, technology and non-profits, each with its own deduction profile and CRA scrutiny patterns. See all industries we serve.
Software applies the rules you already know about. An experienced tax accountant finds the ones you do not: capital cost allowance timing, the small business deduction threshold, shareholder loan repayment rules, and TOSI exposure on family dividends. The fee is usually smaller than the deductions it surfaces.

It depends less on opinion than owners assume. Once the CRA confirms an assessment or reassesses following an objection, the next step is an appeal to the Tax Court of Canada within 90 days. An extension has to be applied for rather than assumed, and the merits of the position do not extend the deadline. Once you know that, the practical question becomes timing and documentation — both of which we handle inside the engagement.
The honest starting point is this: A review is won on documentation created at the time, not on explanations offered afterwards. The CRA asks for the source records behind a figure, and an unsupported claim is simply disallowed. Most reassessments we reverse are not the result of a wrong position — they are the result of a correct position with no contemporaneous paper trail behind it. Everything else we would tell you is tailoring, and tailoring requires seeing your file.
The questions Canadians actually search on this topic, answered plainly. Browse every question in the Canadian tax answers directory.
If you owe nothing, no penalty applies, but a refund and benefit payments such as the Canada child benefit and the GST/HST credit are held up until the return is processed. If you owe, a late-filing penalty is charged and interest runs on the balance and compounds daily from the day after the due date. For the 2025 tax year the deadline was 30 April 2026. File even if you cannot pay, because the penalty is driven by filing, not payment.
Pay through your bank's online banking by adding the CRA as a payee and choosing the right account and year, through My Payment with a debit card, by pre-authorised debit scheduled in My Account, by credit card through a third-party provider that charges its own fee, or at a bank counter with a remittance voucher. For 2025 personal returns the payment deadline was 30 April 2026, including for the self-employed, and interest runs daily on anything unpaid after that.
The CRA no longer runs walk-in counters for general tax help, so there is no office you can visit to file or ask questions. Contact is by phone, by mail, or through My Account and My Business Account; in-person help is limited to arranged appointments in specific programs. Mailing addresses differ by centre and by what you are sending, so use the address printed on your CRA letter or on the CRA's website.
The HST arrived in the late 1990s, when three Atlantic provinces agreed to merge their provincial sales tax with the federal GST into one harmonized tax collected federally. Ontario and others joined later, and British Columbia adopted it before reversing the decision by referendum and returning to PST. Current rates are 13% in Ontario, 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island, and 14% in Nova Scotia since 1 April 2025.
Two separate charges apply. Filing late costs 5% of the balance owing plus 1% for each full month the return is late, to a maximum of 12 months. Paying late costs compound daily interest on the unpaid balance at the CRA's prescribed rate, which is reset every quarter. Interest also runs on the penalty itself. Check the current quarterly rate on the CRA's prescribed interest rates page before estimating what you owe.
Income tax on individuals, corporations and trusts; consumption taxes, where GST is 5% and provinces add HST, PST, QST or RST; payroll levies such as CPP and EI; property tax charged by municipalities; and targeted charges including excise duties and land transfer tax. Capital gains sit inside income tax, with one-half of the gain included for 2025 and 2026. Federal, provincial and municipal governments each levy their own, which is why rates differ by province.
Tax legislation is the written law that imposes and administers tax: federally the Income Tax Act and the Excise Tax Act, plus each province's own statutes and the municipal bylaws behind property tax. A change usually begins as a budget announcement, is drafted into a bill, passes Parliament and takes effect on royal assent. Regulations and CRA guidance sit beneath the statutes and explain administration without replacing them. Some proposals are administered before they pass, and a few never do.
Yes. Hiding income, claiming expenses you did not incur, keeping two sets of books or failing to report offshore accounts is a criminal offence, and convictions can bring fines, full repayment with interest and jail. Lowering tax through an RRSP, a TFSA or genuine business deductions is lawful planning, which is a different thing. If you have unreported income from earlier years, the CRA's Voluntary Disclosures Program may reduce penalties and interest when you come forward first.
Claim everything you are entitled to, and file on time so nothing is clawed back by penalties. Gather every slip, then look at RRSP contributions, childcare and moving costs, medical expenses, tuition, donations, employment or home office expenses and the disability amount. Couples should pool medical and donation claims on one return and split eligible pension income. Carry unused amounts forward instead of losing them, and adjust an earlier return if you missed something.
Most people pay through online banking by adding the CRA as a payee, then choosing the account the money is for, such as personal income tax, GST/HST or payroll, and the exact year or period. You can also pay from CRA My Account or My Business Account, set up pre-authorised debit, or use a third-party card provider. Always apply a payment to the right period, otherwise it sits unallocated and interest keeps running.
No. A private appraisal you order for a mortgage, a separation or an estate is a report to you and is not sent to the assessment authority, so it does not move your property tax bill. Municipal tax is billed on an assessed value set by the provincial assessment body on its own cycle. Renovation permits, a reassessment or a sale can change that value. For income tax, an appraisal only documents value; it creates no tax by itself.
For an individual it is the social insurance number, which the CRA uses to identify you on your return and your benefit accounts. A business gets a business number, extended by a program account for each purpose, such as corporate income tax, payroll and GST/HST. Anyone who must file but cannot obtain a social insurance number, a non-resident for example, applies to the CRA for an individual tax number instead.
