When you earn interest from a Guaranteed Investment Certificate (GIC) in Canada, it’s taxed as regular income. Here’s what you need to know:
- Non-Registered Accounts: GIC interest is taxed annually at your marginal tax rate, even if it’s reinvested. Financial institutions issue a T5 slip for amounts over $50, which you report on your tax return.
- Registered Accounts: GICs in TFSAs grow tax-free, while RRSPs defer taxes until withdrawal. This can save you money, especially if you’re in a lower tax bracket at retirement.
- Multi-Year GICs: Interest must still be reported yearly, even if it compounds and isn’t paid out, which could create tax obligations before you receive the funds.
To minimize taxes, consider holding GICs in registered accounts like TFSAs or RRSPs. Tax planning tools and professional advice can help you make the most of your investments.
When You Must Pay Tax on GIC Interest
Taxable Events for GICs
If you hold a GIC in a non-registered account, the Canada Revenue Agency (CRA) taxes the interest in the year it is earned - whether you withdraw it or reinvest it. This interest income is taxed at your marginal rate [1]. To help you report this, your financial institution will issue a T5 slip by the end of February [4].
Tax Rules for Registered Accounts
The tax rules shift when GICs are held in registered accounts. In a Tax-Free Savings Account (TFSA), any interest earned is entirely tax-free and doesn’t need to be reported as income [4]. For a Registered Retirement Savings Plan (RRSP), taxes on the interest are deferred until you withdraw the funds. This can be advantageous if you’re in a lower tax bracket at the time of withdrawal [1][3]. This differs from non-registered accounts, where multi-year GICs require annual interest reporting, even if the interest remains reinvested.
Multi-Year GICs and Annual Interest Reporting
For multi-year GICs held in non-registered accounts, any accrued interest must be reported each year, regardless of whether you’ve accessed or reinvested it [4]. This can create cash flow challenges, as you may owe taxes on interest you haven’t received yet. Even small amounts, such as those under $50, must be included as income [2][3].
How to Report GIC Interest on Your Tax Return
Tax Forms and Where to Report
If you earn GIC interest in a non-registered account, your financial institution will issue a T5 slip. This slip is required by the Canadian government for residents who have earned or accrued interest during the year [5].
A T5 slip is issued when your investment income exceeds $50. You’ll find the GIC interest listed in Box 13 ("Interest from Canadian sources"). To report this, enter the amount on Line 12100 of your T1 tax return [1][3].
For Quebec residents, the process includes an additional Relevé 3 slip, which is used for provincial tax purposes [5][6].
If your GICs are held in foreign currencies, you’ll need to convert the interest into Canadian dollars. Use either the Bank of Canada’s rate on the payment date or the annual average rate. As Jamie Golombek, a tax expert from CIBC, explains, “This gives you some flexibility in choosing the most advantageous rate” [1]. The CRA then applies your marginal tax rate based on the converted amount.
How GIC Interest Gets Taxed at Your Rate
GIC interest is treated as regular income and taxed at your marginal rate [1]. Unlike capital gains, which benefit from preferential treatment, 100% of the GIC interest earned in non-registered accounts is taxable [1].
Your marginal tax rate depends on your total income and varies by province. For those in higher income brackets, the tax on GIC interest will be greater compared to someone in a lower bracket. To avoid this, many Canadians choose to hold GICs in registered accounts like TFSAs or RRSPs, where the interest can grow tax-free.
It’s important to note that interest is taxed based on when it is paid or accrued during the tax year. Even if you don’t withdraw the interest, you’re still required to report and pay taxes on it if it was earned in a non-registered account [1].
Reporting Small Amounts Under $50
Even small amounts of GIC interest must be reported on your tax return. If your interest is under $50, financial institutions typically won’t issue a T5 slip. However, this doesn’t exempt you from reporting it [2][7]. Use bank statements or other records to track the interest earned. If the exact amount is unclear, provide your best estimate when filing your return.
This requirement often surprises Canadians, especially those with smaller GIC investments. However, it’s important to remember that all interest income, regardless of the amount, must be included in your tax return [3][8].
Tax Differences: Registered vs Non-Registered Accounts
Side-by-Side Tax Treatment Comparison
When it comes to GIC returns, the type of account you choose - registered or non-registered - can make a big difference in how much tax you pay. To make things clearer, here’s a breakdown of how TFSAs, RRSPs, and non-registered accounts handle GIC interest:
| Feature | TFSA | RRSP | Non-Registered |
|---|---|---|---|
| Contribution Tax Deduction | No | Yes | No |
| Tax on Investment Growth | Tax-free | Tax-deferred | Taxable annually |
| Tax on Withdrawals | No | Yes | No |
| Contribution Limits | Yes | Yes | No |
| Flexibility | More flexible | Less flexible | More flexible |
These differences directly impact your tax bill. For example, if you earn $1,000 in interest in a non-registered account and you’re in a 40% tax bracket, you’ll owe about $400 in taxes.
TFSAs, on the other hand, allow your interest earnings to grow tax-free - even though contributions aren’t deductible. RRSPs provide tax relief upfront by reducing your taxable income, but you’ll pay taxes on withdrawals later. Knowing how each account works can help you make smarter decisions to boost your after-tax returns.
How to Keep More Money After Tax
If you want to minimize taxes on your GIC earnings, registered accounts are your best bet. For example, holding a GIC in a TFSA is a smart move if you have contribution room. Why? Because any interest earned is completely tax-free[9].
For those in higher tax brackets, RRSPs are also a great option. They give you immediate tax savings through deductible contributions and let your investments grow tax-deferred until retirement. By contrast, non-registered accounts tax your interest earnings every year, which can chip away at your returns over time.
Ultimately, the right choice depends on your tax bracket and financial goals. If you’re investing in multi-year GICs, using registered accounts whenever possible can help you keep more of your earnings.

Understanding how GIC interest is taxed is just the beginning. To refine your strategy, there are several tools and resources available that can help you make informed decisions.
Tax Calculation Tools
Online calculators can be a great way to estimate your after-tax GIC returns. One standout option is the Wealth Awesome GIC calculator, which does more than just basic interest calculations. It provides insights into potential returns for various GIC types, such as cashable versus non-redeemable, fixed rate versus market-linked, and short-term versus long-term investments [11]. This tool allows you to compare different GIC structures and evaluate their tax implications.
One of its key features is the ability to display both annual and monthly compounding results [11]. For instance, it can help you weigh the benefits of a one-year GIC with annual interest payments against a multi-year GIC where the interest compounds but is taxed yearly.
Additionally, provincial tax calculators take into account both federal and provincial tax rates, offering a more accurate picture of your after-tax returns. These tools highlight the importance of precise tax planning [10].
If you're looking to deepen your understanding of GIC tax treatment, there are also valuable educational resources to explore.
Learning Resources
Educational tools can complement your calculations, helping you develop smarter GIC tax strategies. For example, Wealth Awesome provides detailed information on registered GIC types and the specific benefits tied to different account options [11].
Their platform also tracks historical GIC interest rates, which can offer insights into market trends and help you time your investments more effectively [11]. For those preparing their taxes, TurboTax Assist & Review (priced between $70 and $150) offers both online and desktop options to ensure accurate reporting of GIC interest income on Line 12100 of your tax return [10]. While not specifically tailored to GICs, this tool can be a reliable resource for managing your overall tax obligations.
A word of caution: Many financial platforms, including Wealth Awesome, clearly state that their content is for informational purposes only and not financial advice [11]. They strongly recommend consulting with a licensed professional before making major investment or tax planning decisions. This is especially critical for GIC tax planning, as your optimal approach will depend on factors like your tax bracket, available contribution room, and personal financial goals.
Conclusion
To wrap up, let’s revisit how you can make the most of your GIC investments by keeping tax planning in mind.
The way GIC interest is taxed plays a big role in your overall returns. Interest earned in non-registered accounts is taxed fully at your marginal rate, while registered accounts like TFSAs and RRSPs offer valuable tax advantages[1][4].
For instance, in Alberta, individuals in the highest tax bracket might pay 39.00% on GIC interest income, whereas capital gains are taxed at a much lower rate of 19.50%[12]. This highlights why registered accounts can be a game changer when it comes to reducing your tax load.
It’s also crucial to ensure that all GIC interest income is reported accurately, as required by law[1][4].
Thankfully, modern tools make tax planning for GICs simpler than ever. Whether you turn to online calculators or consult a tax professional, these resources can help you fine-tune your investment strategy.

While taxes are an important consideration, they shouldn’t deter you from investing in GICs. These investments remain a dependable, low-risk choice, particularly when held in the right type of account. By understanding the tax landscape and using registered accounts wisely, you can maximise your returns and strengthen your financial future.
FAQs
How does holding a GIC in a TFSA or RRSP affect my taxes compared to a non-registered account?
When you invest in a GIC within a registered account like a TFSA (Tax-Free Savings Account) or an RRSP (Registered Retirement Savings Plan), the interest you earn gets some tax advantages. In a TFSA, the interest is entirely tax-free - even when you take the money out. With an RRSP, the interest grows tax-deferred, meaning you won’t owe taxes until you withdraw the funds, which often happens during retirement.
On the other hand, if your GIC is held in a non-registered account, the interest earned is fully taxable as income in the year it’s paid. This amount needs to be reported on your annual tax return and will be taxed at your marginal tax rate in Canada.
How can I reduce the taxes I pay on GIC interest income in Canada?
To reduce the taxes you pay on GIC interest income in Canada, think about keeping your GICs in registered accounts like a Tax-Free Savings Account (TFSA) or a Registered Retirement Savings Plan (RRSP). The interest you earn in these accounts is either tax-free (TFSA) or tax-deferred (RRSP), making them excellent tools for managing your tax obligations.
If your GICs are held in non-registered accounts, the interest is fully taxable as income in the year it is earned. To help offset this, you might consider strategies like applying capital losses from other investments to lower your taxable income or maximizing your RRSP contributions to reduce your overall tax burden. Using registered accounts is by far the easiest and most effective way to cut down on taxes tied to GIC interest income in Canada.
What should I do if I earn GIC interest under $50 and don’t receive a T5 slip?
In Canada, even if your financial institution doesn’t provide a T5 slip for GIC interest under $50, you’re still required to report that income on your tax return. All interest income is subject to taxation, no matter the amount or whether you receive a slip.
To stay compliant, calculate the total interest earned and include it in the correct section of your tax return. Accuracy is key, as the CRA expects every dollar of taxable income to be reported, even when the amounts seem minor.
