Five Years of Rental Income the CRA Found Before They Fixed It

The situation

Alejandro had been a registered nurse for close to fifteen years, and about five years ago he incorporated a small consulting business on the side, delivering clinical training and compliance workshops to hospitals and long-term care operators around the Greater Toronto Area. The corporation billed clients, paid him a modest salary and periodic dividends, and filed a corporate return every year with the help of an accountant. On that front, the paperwork was in reasonably good order.

The problem sat somewhere else entirely. A few years before the corporation existed, Alejandro and his partner Mateo, a real estate agent, had bought a one-bedroom condo in Etobicoke as an investment, using a small inheritance and some savings for the down payment. They rented it out from the start. Mateo, given his work in real estate, handled finding tenants and setting rent, and the monthly payments landed in a joint personal bank account the couple used for a mix of household and investment expenses. Neither of them ever mentioned the condo to Alejandro's accountant, who only ever saw the corporate books, and neither filed it on their own personal returns. It was not a deliberate decision to hide anything — it was more that the rental had always existed alongside their main jobs, never got raised at tax time, and the longer it went unreported, the harder it felt to bring up.

What the review found

The CRA's compliance program routinely cross-references property records, rental listing data and reported income, and a mismatch on a rental property with no corresponding income on either owner's personal return is exactly the kind of gap that gets flagged. Alejandro and Mateo received a letter from the CRA requesting supporting documentation for the Etobicoke condo, including tenant leases, rent deposits and expense records, going back five years.

Once they brought everything to Treadstone Law, the scope of the problem became clear. Over five years, the condo had generated net rental income — rent collected minus mortgage interest, condo fees, property tax and repairs — of roughly $150,000 in total, none of which had been reported by either owner. Left unaddressed, that gap exposed them to three things at once: the underlying tax on the unreported income, interest that had been accruing since each return was originally due, and a penalty. Because the CRA's letter framed the omission as a pattern repeated across several consecutive years rather than a single missed year, the file was flagged for a gross negligence penalty — a much steeper penalty, calculated as a percentage of the tax understated, reserved for cases where the CRA considers the taxpayer knowingly, or through wilful blindness, failed to report income, as opposed to an honest oversight.

One door was already closed to them by the time they called. The CRA's Voluntary Disclosures Program lets a taxpayer come forward on their own initiative to correct a filing error, often in exchange for reduced or eliminated penalties and some interest relief — but it is only available before the CRA has already contacted the taxpayer about the same issue. Because the review letter had already arrived, a voluntary disclosure was no longer on the table. The remaining path was to respond to the review accurately, then negotiate the penalty and interest through the CRA's ordinary channels.

What we did

1. Reconstructed five years of rental figures from the source documents. Working from bank statements, condo fee invoices, mortgage statements and whatever receipts Mateo had kept for repairs and appliances, we rebuilt an accurate year-by-year net rental income calculation, rather than letting the CRA's own estimate — which tends to be conservative in the government's favour when records are incomplete — stand unchallenged.
2. Corrected who should have reported what. Because the condo was held jointly and the down payment had come from a mix of Alejandro's inheritance and joint savings, we worked through how the net rental income should properly be split between the two owners for tax purposes, rather than assuming an even fifty-fifty division that might not reflect their actual respective contributions to the property.
3. Confirmed the corporation was not part of the problem. A separate concern was whether the CRA's review might expand into the consulting corporation's own filings, given the connection between Alejandro's two sets of finances. We reviewed the corporate returns, confirmed they were unrelated to the personal rental omission, and kept our response narrowly focused on the personal issue so the review did not widen unnecessarily.
4. Submitted amended figures directly rather than waiting for a CRA-issued reassessment. We prepared and submitted the corrected five-year rental income figures for both Alejandro and Mateo proactively, along with supporting documentation, instead of waiting for the CRA to issue its own numbers first and having to dispute them afterward.
5. Made written representations against the gross negligence penalty. We argued that the omission, while it spanned several years, reflected disorganized personal recordkeeping and a breakdown in communication between the couple and their accountant rather than a knowing or wilfully blind decision to conceal income — the couple had never taken steps to hide the rent, deposited it into an ordinary joint account, and cooperated fully once contacted. We asked that any penalty be assessed at the ordinary repeated-failure-to-report rate instead, and separately requested interest relief for one year where a documented family medical emergency had delayed their ability to respond to an earlier CRA inquiry letter.
6. Arranged a payment plan once the numbers were settled. With neither owner able to pay the full reassessed amount as a lump sum without depleting savings meant for other purposes, we negotiated a structured monthly payment arrangement directly with the CRA's collections officer, set at a level Alejandro and Mateo could sustain alongside their existing income.

The outcome

The CRA accepted the corrected five-year rental figures largely as submitted, with only a small adjustment to the deductible portion of one year's repair costs. On the tax owing across both owners, that came to roughly $45,000 in additional personal tax. The CRA had initially signalled it would apply the gross negligence penalty at the full rate, which on these numbers would have added roughly $22,500, plus accumulated interest of about $18,000 — putting the total amount in dispute at around $85,500.

The written representations narrowed that outcome without eliminating it. The CRA agreed the conduct did not meet the bar for gross negligence and reduced the penalty to the ordinary repeated-failure rate, cutting it to roughly $4,500. It also granted partial interest relief for the year affected by the medical emergency, trimming the interest portion to about $15,000. The final reassessment came to roughly $64,500 across tax, penalty and interest combined, split between Alejandro and Mateo according to their corrected ownership shares, and payable through the instalment arrangement rather than in one payment.

It was not a clean win — the couple still owed real money for years of income that should have been reported at the time, and the interest clock had not been fully switched off. But the gap between the roughly $85,500 the CRA initially signalled and the roughly $64,500 they ultimately settled represented a meaningful, honestly earned reduction, achieved because the underlying numbers were correct, the penalty argument was grounded in an accurate account of what actually happened, and the response came promptly once the review letter arrived. Alejandro's consulting corporation was never drawn into the review at all, and both owners now file the rental income on their personal returns each year as a matter of course.
