Quebec Tax Debt: the Payment Arrangement, Simply Explained

Published on October 7, 2026 · 5 min read · By CalculQuébec

You filed your return, and the result gives you chills: you owe money to Revenu Québec, the CRA, or both — and you don't have it. First, breathe: you're far from alone, and more importantly, there are official solutions designed exactly for this. Here's how to get through it cleanly, without panicking.

Golden rule: file on time, even if you can't pay

This is the most important advice in this article, and it comes straight from the CRA: even if you can't pay your full balance, file your return before the deadline. That way you avoid the late-filing penalty, which piles on top of interest. Not filing doesn't make the debt disappear — it makes it worse. If you're already past the deadline, file now anyway: every additional month only adds to the bill, and the CRA looks more favourably on taxpayers who come forward on their own rather than waiting to be chased.

Revenu Québec: the online payment arrangement

Revenu Québec lets you propose a pre-authorized debit payment arrangement: equal, automated monthly payments spread over a maximum of 12 consecutive months. Withdrawals come straight from your bank account, on the 1st or the 16th of each month.

Conditions to meet:

Your tax returns are up to date
You have no other payment arrangement in force
You have committed no tax offence in the last two years

Document to have handy: your notice of assessment, or any other document showing your unpaid balance.

The fastest path: use the online service in Mon dossier pour les citoyens. You can also fill out form LM-31 and mail it, but Revenu Québec is clear: it's slower, and interest keeps accumulating meanwhile.

The CRA: an arrangement based on your ability to pay

On the federal side, the CRA can also help you set up a payment arrangement if you can't pay in full. The collections officer will consider your ability to pay — but expect to provide supporting documents on your income, expenses, assets and financial obligations. The CRA also expects you to have first tried reasonable ways to raise the funds (borrowing, reorganizing your finances).

How to request it: call 1-888-863-8661 (Monday to Friday, 7 a.m. to 11 p.m. Eastern Time), or use pre-authorized debit in CRA My Account to schedule a series of payments. And if your financial situation changes during the arrangement, call: it can be adjusted.

What does waiting cost? Current rates

Interest on tax debts is set every quarter. Here are the current rates, verified today:

Agency	Period	Interest rate on the debt
Revenu Québec	Oct. 1 to Dec. 31, 2026	7%
Revenu Québec	Jan. 1 to Mar. 31, 2026	8%
CRA (unpaid tax)	Oct. 1 to Dec. 31, 2026	7%

7% may sound "not so bad" next to a credit card. But this interest is calculated daily on your balance, on top of any penalties. Every month of waiting has a price.

Worked example: $6,000 in tax debt

Take a $6,000 debt to Revenu Québec, repaid over a 12-month arrangement at the current 7% rate:

Monthly payment: $519.16
Total repaid: $6,229.93
Interest paid: $229.93

Now compare with the tempting — but costly — idea of putting that $6,000 on a 19.99% credit card over 12 months:

Monthly payment: $555.78
Interest paid: $669.34

Difference: $439.41 more in interest. The takeaway is simple: a payment arrangement with the tax authorities costs almost three times less than "fixing" your tax debt with your card.

Your step-by-step action plan

File your return on time, even if you can't pay. Non-negotiable.
Know your exact balance: read your Revenu Québec notice of assessment and your CRA notice.
Request your arrangement: online in Mon dossier (Revenu Québec, 12 months maximum) and/or at 1-888-863-8661 (CRA).
Honour the debits: missing one can collapse the arrangement and reopen the door to collection action.
Stop it from happening again: if you're self-employed, adjust your instalment payments. And did you know an RRSP contribution can reduce the tax you owe? Our [RRSP vs FHSA guide](/en/blog/rrsp-fhsa) explains how.

Mistakes that make everything worse

Ignoring the debt. The tax authorities can garnish your wages, seize bank accounts, or offset future refunds and credits. Acting fast avoids all of that.
Not filing a return. The late-filing penalty stacks on top of interest: you pay for doing nothing.
Paying the taxman with your credit card. As the example above shows, it costs nearly $440 more on $6,000.

Special case: are you self-employed?

If you work for yourself, tax debt often comes from underestimated instalment payments. Two habits to stop it from happening again:

Set tax money aside with every payment you receive. A simple rule: move 25 to 30% of each invoice into a separate account before paying yourself. Tax money is never "your" money.
Adjust your instalments as soon as your income changes. Waiting for the CRA or Revenu Québec notice means reacting; adjusting during the year means staying in control.

And don't forget GST/QST if you're registered: amounts you collect don't belong to you either. Fifteen minutes of monthly tracking spares you a multi-thousand-dollar surprise in the spring.

What never to do

Counting on your next refund to cover the current arrangement. If your refund gets offset against your debt — and the tax authorities can do that even during an arrangement — your plan collapses.
Borrowing at 20% to pay a 7% debt. We ran the numbers above: it's a losing move every time.
Negotiating without knowing your exact balance. Have your notice of assessment ready before calling: an officer helps much faster when you know your numbers.

The bottom line

Tax debt isn't a catastrophe: it's an administrative problem with an official procedure. Payment arrangement, 12 months maximum on the Revenu Québec side, 7% interest right now: the rules are clear and the tools exist. The only real danger is doing nothing.

Frequently asked questions

Does the payment arrangement stop interest?

No. Interest keeps accruing at the prescribed rate in force (7% for the last quarter of 2026, on both sides). The arrangement protects you from collection action and spreads the pain, but it doesn't erase interest — which is why repaying as fast as possible matters.

What happens if I do nothing?

The tax authorities can take collection action: garnish your wages or bank accounts, and offset future tax refunds or credits (GST/HST). Acting quickly and requesting an arrangement keeps you out of that territory.

Can I change my arrangement if my situation changes?

Yes, on both sides. If your financial situation changes during the arrangement, contact Revenu Québec (Mon dossier) or the CRA (1-888-863-8661) to discuss it. Adjusting the arrangement beats missing a payment.

Is it smart to pay my tax debt with my credit card?

As our example shows, paying $6,000 in tax with a 19.99% card costs $669.34 in interest over 12 months, versus $229.93 with a 7% arrangement. That's almost three times more expensive: avoid it.

I owe money to both Revenu Québec and the CRA: where do I start?

Do both in parallel: the online arrangement in Mon dossier for Revenu Québec (12 months maximum) and a call to 1-888-863-8661 for the CRA. Rates are identical right now (7%), so don't neglect either one.
