What Happens If You Fall Behind on CRA Payments

Missing a CRA payment feels worse than missing most other bills because the consequences are faster and harder to undo. CRA has collection powers that most creditors do not have. They can garnish your bank account without going to court. Understanding what happens, and in what order, gives you a much better chance of managing the situation before it escalates.

Note: this post explains how the process generally works. It is not tax advice. For your specific situation, talk to your accountant or a tax professional.

How CRA Interest and Penalties Work

CRA charges compound daily interest on overdue balances. The rate is set quarterly and is typically the Bank of Canada overnight rate plus a few percentage points. On corporate tax balances, the interest starts the day after the balance was due. On payroll remittances, interest can start accruing even faster.

Penalties work differently depending on what you are late on. A late-filed corporate tax return triggers a penalty even if no tax is owing. Payroll remittance failures carry their own penalty structure, and the penalties can be significant even on small missed amounts. The specific rates change, so always check CRA directly or ask your accountant for current figures rather than relying on any article.

What Owners Get Wrong

The most expensive mistake is ignoring the problem and hoping it resolves itself. CRA does not forget. Interest compounds every day you do not pay, and the balance grows faster than most people expect.

The second mistake is prioritizing other creditors over CRA on payroll remittances. If you have employees and you collect their CPP, EI, and income tax deductions, that money is held in trust for CRA. It is not your money to use for operations. Using it anyway exposes you to personal liability, even through a corporation, and that liability does not disappear in bankruptcy.

The Collection Escalation Process

CRA generally follows a sequence before taking enforcement action, though the timeline depends on the amount and the type of debt. Early notices are letters and statements asking you to pay or contact them. If no action is taken, the file can move to a collections officer who may contact you directly. From there, CRA can issue third-party demands to your bank or customers, requiring them to redirect money owed to you toward your CRA debt. This can happen without a court order. They can also register a lien against your business property.

In practice, most businesses receive some warning before enforcement action. But the assumption that CRA will notify you multiple times before acting is dangerous. If you know you are behind, do not wait for a call. Call them first.

The CFO Perspective

A client once came to me after discovering a payroll remittance shortfall that had been building quietly for eight months. By the time it surfaced, the balance including penalties and interest was roughly double what the original missed amounts had been. The issue was not that the payroll system was wrong. It was that nobody was reconciling the remittances to the actual amounts withheld each period. A 10-minute monthly check would have caught this in month one.

The lesson is not that CRA will destroy you if you miss a payment. The lesson is that small gaps compound quickly, and catching them early is always cheaper than addressing them late.

What to Do If You Are Behind

1. Get a clear picture of the actual balance. Log into your CRA My Business Account and pull the current balance for each account: corporate income tax, HST/GST, and payroll. The balance in your books may not match what CRA shows if there are unprocessed payments, penalties, or interest. Know the real number.
2. Contact CRA before they contact you. If you cannot pay in full, calling the collections line proactively generally results in better outcomes than waiting for a demand. CRA is more likely to discuss a payment arrangement when you initiate the conversation.
3. Ask about a payment arrangement. CRA does offer formal payment arrangements for businesses that cannot pay in full immediately. The terms depend on the amount, the type of debt, and your demonstrated ability to pay. Your accountant can help you prepare a proposal.
4. Prioritize payroll remittances above other CRA debts. As noted above, the personal liability exposure on payroll remittances makes them the most urgent obligation to clear. Do not negotiate a payment plan on corporate tax while continuing to fall behind on remittances.
5. Fix the underlying cash flow problem. A payment arrangement buys time, but if the cash flow problem that caused the shortfall is still there, you will fall behind again. Use the breathing room to build a proper cash flow forecast and identify where the gap is coming from.
6. Get professional help early. If the balance is large or growing, a tax accountant or tax lawyer who deals with CRA regularly is worth the cost. They know how to navigate the collections process and what arguments are available to you.
