You owe the CRA and can't pay: the order of operations

File on time anyway. Filing late and paying late are two separate charges, and sending in a return you cannot fund removes one of them at no cost. Then sort what you owe, because the dollars are not interchangeable: amounts your corporation withheld from an employee or collected from a customer are held in trust, and a director can be assessed personally for them. Corporate income tax carries no such exposure. Then call before the account moves to collections — a payment arrangement is ordinary, and it is negotiated early rather than after a requirement to pay has been served on your bank.

Filing late and paying late are two different failures

Interest on an unpaid balance starts the day after the balance-due date, compounds daily, and runs at a prescribed rate the CRA resets quarterly. Nothing you do about the return changes that. The late-filing penalty is a separate charge with its own trigger: a percentage of the unpaid tax the moment the return is late, a further percentage for each full month it stays late, and a harsher version for repeat failures. The deadlines guide sets out both clocks in full.

The interaction is what costs owners money. The penalty is calculated on tax still unpaid when the return was due — so the corporation with no cash is precisely the corporation for which that penalty is largest. Filing on time with nothing attached costs the corporation nothing and stops the larger of the two numbers from ever being computed. The same holds on the personal side: your T1 balance is due April 30 whether or not the June 15 filing extension is yours, and filing it is free.

The dollars you owe are not interchangeable

Three kinds of debt reach an incorporated owner, and only one of them is ordinary corporate liability.

Corporate income tax is the corporation’s own. If it goes unpaid, the corporation owes it, with interest, and limited liability does its usual job. Source deductions withheld from an employee’s pay and GST/HST charged to a customer are a different thing entirely. That money is held in trust — collected on the CRA’s behalf and never the corporation’s. Which is why a director can be assessed personally for unremitted source deductions and GST/HST. Limited liability does not cover money held in trust.

Two consequences follow from the same characterization. The failure-to-remit penalty is charged on the amount you failed to remit rather than on the tax you eventually owe, so a cash-flow problem in March produces a number unrelated to your final bill. And collection starts sooner: income tax debts generally get a restricted period after assessment before legal collection can begin, and trust amounts generally do not.

Nobody needs to be told which of those is uncomfortable. The point is narrower — an owner deciding what to pay by the size of the numbers is sorting on the wrong field.

A payment arrangement is a schedule, not relief

Payment arrangements exist and are ordinary. Before a file is assigned to a collections officer, the CRA’s debt-management line will generally take one over the phone: you propose a schedule, the CRA accepts, adjusts or declines it, and payments usually come out by pre-authorized debit on the dates agreed.

What the conversation generally covers:

• What the corporation can pay now, what it can pay monthly, and why the balance came up short. Larger or longer arrangements generally draw financial disclosure — bank statements, receivables, assets — rather than a number over the phone.
• Whether ordinary commercial credit is available to you. The CRA generally asks, on the reasoning that it is a tax collector rather than a lender.
• Staying current. Filing new returns and making new remittances on time is generally a condition, and a missed payment on the arrangement generally ends it rather than amending it.

Interest keeps running at the prescribed rate throughout. An arrangement buys time and stops the collection sequence advancing; it does not reduce the debt or pause the meter. Nor is that interest deductible to the corporation, which is why a CRA balance and a bank loan are not the same price even at an identical rate.

What collection can do, and how soon

The sequence is procedural and it is documented in the letters guide — a reminder, a legal warning letter, then a requirement to pay served on your bank or on a customer who owes your corporation money, with garnishment and liens past that. Two things about the early part matter while you still have room to act.

The first is that the CRA generally warns before it acts. A requirement to pay does not ordinarily arrive as the first contact; the reminder and the legal warning letter generally come first, which is why an unopened envelope is the expensive kind of mistake. The second is the asymmetry above: the restricted period that generally applies to an assessed income tax debt gives you a window that a trust-amount debt does not.

Taxpayer-relief provisions sit alongside all of this. They give the CRA discretion to cancel or waive penalties and interest — never the tax itself — where circumstances were beyond your control, where the CRA caused a delay or made an error, and in some cases on inability to pay. Relief is applied for on a prescribed form, decided case by case, and limited to a set number of prior years measured back from the request. A request is not a stay: the balance keeps behaving like a balance while it is considered.

A worked example: C$20,000 against three due dates

Illustrative, round numbers, December 31 year-end. A contractor’s corporation with one employee besides the owner, filing GST/HST quarterly. A large customer paid ninety days late, and the year’s tax came due inside the gap.

Three amounts land in six weeks. C$48,000 of corporate income tax for the year just ended, due March 31 as a CCPC that claimed the small-business deduction. C$6,000 of source deductions withheld from March payroll, due April 15. C$14,000 of net GST/HST for the first quarter, due April 30. That is C$68,000. The bank account holds C$20,000 and April’s collections are already committed to suppliers.

Sorted by whose money it was, two of the three numbers were never the corporation’s: the C$6,000 withheld from an employee’s pay and the C$14,000 charged to customers on invoices they have already settled. Together, C$20,000 — the whole balance. The C$48,000 is the corporation’s own liability, and it is the only one of the three with no personal exposure attached to it.

The filings are not the variable in any version of this. The GST/HST return goes in April 30 whatever accompanies it; the T2 goes in June 30 whatever the balance says. An unfiled T2 costs the corporation interest on C$48,000 plus a penalty calculated on the same C$48,000. A filed one costs the interest.

What remains is a C$48,000 conversation, opened in April while the corporation is current on everything else — which is the fact that makes an arrangement straightforward — rather than in September when a legal warning letter forces it. And paying that C$48,000 down over the summer does not pause the current year’s instalments; the deadlines guide works that second-year squeeze through with the arithmetic attached.

What Cadence does

We file on time whether or not the balance can be funded, which is what the fixed fee and the filing guarantee are built around: the guarantee turns on your records arriving by the agreed date, not on your bank balance. When a quarterly estimate shows a balance the year cannot cover, you hear it then rather than at the due date, and we separate the trust amounts from the corporate ones before anyone decides what to pay. Account questions, arrears notices and ordinary payment-arrangement calls are core CRA support, included from the Year-Round Tax Partner package up; the annual-returns-only tier covers the returns themselves. A live collections file, a taxpayer-relief request or a voluntary disclosure is different work — we take those selectively or refer them out, and we say which at the start.
