Refinance to pay CRA debt: when it beats a payment arrangement, and when it doesn't

Short answer: You can often refinance to pay CRA debt, and it can stop the interest and collection pressure in one step. But it isn't automatically the cheaper option. The CRA charges 7% a year on overdue taxes for October 1 to December 31, 2026, and that interest is charged daily ^[3][5]. A refinance swaps that for a lower mortgage rate, plus closing costs and possibly a penalty. If you can repay within a few years, a CRA payment arrangement may cost about the same or less. Refinancing usually earns its keep when legal action is close, a lien is already registered, or you're also carrying other high-interest debt.

This guide is for Canadian homeowners with a personal income tax balance, or a self-employed GST/HST balance, who are weighing their home equity against a CRA payment plan. It's general information, not tax advice; an accountant can confirm what you actually owe. If you're carrying other debts too, our debt consolidation mortgage page shows how they can be combined.

How CRA debt grows, and what happens if it isn't paid

For individuals, the balance owing is due April 30 after the tax year. From the next day, the CRA charges interest on the full unpaid balance every day until it's paid, so you end up paying interest on interest ^[5]. The rate is set every quarter; for October 1 to December 31, 2026, it's 7% on overdue taxes, CPP contributions and EI premiums, and on overdue GST/HST ^[3]. Filing late adds a separate penalty of 5% of the balance plus 1% for each full month late, up to 12 months ^[9], so file on time even when you can't pay.

If a debt isn't paid or covered by an arrangement, the CRA follows set steps ^[1][2]:

The calmer news: there are several exits at every stage, and talking to the CRA early keeps the most options open.

Option 1: a CRA payment arrangement

You can schedule pre-authorized debit payments in your CRA account, or call the CRA to set up an arrangement ^[4]. The terms are simple: make every payment on the agreed date, file future returns on time and stay current. If you pay less than agreed without changing the arrangement first, the CRA may take legal action ^[4].

What an arrangement doesn't do is stop the interest. The CRA keeps charging interest on the unpaid balance until it's paid in full, so payments should include an estimate of interest ^[5]. If paying the interest is a real hardship, you can also ask for relief: the CRA may cancel or waive interest, in whole or in part, when it confirms you can't pay, though it doesn't cancel the tax itself ^[6].

Option 2: refinance to pay CRA debt

A refinance replaces your current mortgage with a larger one, and the extra pays the CRA directly at closing. FCAC notes you may usually borrow up to 80% of your home's value against your equity ^[7]. A HELOC (up to 65% of value) or a second mortgage (up to 80% of value minus your first mortgage) can also work ^[7]; see how second mortgages work if your first-mortgage rate is worth keeping.

At a bank, you'll also need to qualify at the minimum qualifying rate: the greater of your contract rate plus 2% or 5.25% ^[8]. The refinance requirements guide covers the rest.

Worked example: $40,000 owed to the CRA

Example (illustrative): a homeowner owes the CRA $40,000. The home is worth $700,000 with a $380,000 mortgage. We've assumed a 4.50% refinance rate and $3,000 of legal and appraisal costs, with no prepayment penalty (for example, at renewal). These are assumptions for the math, not quotes.

The new mortgage would be about $423,000, or roughly 60% of the home's value, within the 80% limit ^[7]. Look at what the table shows. On a $40,000 balance, the rate gap alone barely covers the closing costs if you repay quickly. Spreading it over 25 years makes the monthly payment small but the total interest far larger. A refinance works best as a tool to stop collection action and then pay the amount down fast.

When refinancing tends to make sense

• Legal action is close or has started. A garnishment or a registered lien can affect your income, your accounts and your ability to sell ^[1][2]. Paying the balance in full resolves the debt, and in most cases the CRA removes a lien once the debt is paid ^[2].
• You're renewing anyway. At renewal there's usually no prepayment penalty, so the main costs are legal and appraisal fees.
• The CRA isn't your only debt. If credit cards or lines of credit sit alongside the tax balance, combining them can make the cost math work; our debt consolidation calculator helps you compare.
• The arrangement payment doesn't fit your budget. A longer amortization can lower the payment, as long as you plan to prepay when you can.

What lenders need to see

1. All returns filed. In our experience, lenders won't finish an approval while a return is outstanding.
2. Your latest Notices of Assessment and a current CRA statement showing the exact amount owed.
3. Payout at closing. In practice, the lawyer usually pays the CRA directly from the refinance proceeds, and a registered lien has to be cleared as part of closing.
4. Income proof. In our experience, self-employed borrowers are usually asked for two years of returns and assessments; see our self-employed refinance guide.
5. A plan for next year's taxes. Setting aside tax as you earn helps stop the balance coming back.

When it may not be the right move

• A large penalty applies. Breaking a fixed mortgage mid-term can cost more than you'd save; check our refinance break-even method first.
• The balance is small or nearly paid. A CRA arrangement or a short-term payment plan may cost less than closing costs.
• You don't qualify at a regular lender. Alternative or private options cost more. If credit is the issue, read refinancing with bad credit.
• The amount owed is in dispute. Talk to an accountant about filing an objection before you borrow to pay a number you think is wrong.

To refinance to pay CRA debt is a trade: tax interest charged daily becomes secured debt on your home at a lower rate. It can stop collection action quickly and give you breathing room. Compare it honestly with a CRA arrangement, keep the repayment period short, and file every return on time. For a full picture of your options, visit our mortgage refinancing page.
