Where to Put Your TFSA on Your Tax Return: RC243 and U.S. Forms

A Tax-Free Savings Account does not go anywhere on your Canadian T1. Where to put a TFSA on your tax return has a short answer for most Canadian residents: nowhere. Contributions are made with after-tax dollars, growth inside the account is tax-free, and withdrawals are not income, so no line, schedule, or slip on the T1 exists for routine TFSA activity. You only file something in Canada if you broke a TFSA rule, in which case you use a separate return called the RC243. If you are a U.S. citizen, green card holder, or U.S. tax resident, the answer changes completely, because the IRS does not treat the TFSA as tax-sheltered and expects the account and its income to appear on several U.S. forms.

Nothing Goes on the T1 for Normal TFSA Activity

Interest, dividends, and capital gains earned inside a TFSA are not reported on any schedule or line of the T1. Withdrawals are not reported either, and the Canada Revenue Agency does not count them when calculating income-tested benefits like the Canada Child Benefit, Old Age Security, or the GST/HST credit.¹

Your TFSA issuer reports contributions and withdrawals directly to the CRA, which tracks your contribution room automatically. You can check your available room in CRA My Account.² Nothing about that tracking flows onto your T1.

When You Do File Something in Canada: Form RC243

The CRA imposes tax on TFSA holders in four situations, and each is reported on Form RC243, the Tax-Free Savings Account (TFSA) Return, not on the T1.³

Excess contributions: contributing more than your available room is taxed at 1% per month on the highest excess amount in each month it remains in the account.
Non-resident contributions: contributing while you are not a Canadian resident is taxed at 1% per month on those contributions.
Prohibited investments: holding an investment in which you have a significant interest in the issuer results in a tax equal to 50% of the fair market value of the investment when it was acquired or became prohibited.⁴
Advantages: transactions that artificially inflate the account’s value, such as deliberate over-contributions designed to shelter specific gains, attract a 100% tax on the income or gain attributable to the arrangement.

Over-contributions are the most common trigger. If you are $5,000 over your limit for six months, the tax is $5,000 × 1% × 6 = $300.⁵ The most common cause is withdrawing money and recontributing it in the same calendar year. Withdrawal room only returns on January 1 of the year after the withdrawal. If you realize you’ve over-contributed, withdraw the excess right away. The CRA specifically says not to wait for a notice, because the 1% keeps accruing every month the excess sits there.⁶

Filing the RC243

The RC243 is due June 30 of the year after the year the tax applies. Tax owing for 2025 is due June 30, 2026. This is a different deadline and a different destination from the T1.⁷ To complete it, identify the highest excess amount in your account for each month it existed, using your financial institution’s monthly statements or CRA My Account, then multiply by 1% for each applicable month.⁵

You can submit the completed return through the “Submit documents” feature in CRA My Account, or mail it to the TFSA Processing Unit at the Sudbury Tax Centre (Post Office Box 20000, Station A, Sudbury ON P3A 5C1) or the Winnipeg Tax Centre (Post Office Box 14000, Station Main, Winnipeg MB R3C 3M2).⁷ If the over-contribution was a genuine mistake and you corrected it quickly, you can ask the CRA to waive or cancel the tax by sending a letter explaining what happened, using CRA My Account or the same mailing addresses.

If You’re a U.S. Person, the TFSA Goes on Several U.S. Forms

If you are a U.S. citizen, green card holder, or U.S. tax resident, the IRS does not recognize the TFSA as a tax-sheltered account. Where it is held in a trust arrangement, the IRS treats it as a foreign grantor trust, meaning all interest, dividends, and capital gains earned inside the account are taxable on your U.S. return in the year earned, even if you never withdraw a dollar.⁸

On Form 1040, the TFSA’s investment income goes on the applicable schedules the same way any taxable investment account’s income would. Convert every amount from Canadian to U.S. dollars using the exchange rate that applied when you received or accrued each item; the IRS accepts rates from banks, the Federal Reserve, xe.com, or oanda.com.⁹ Beyond the income itself, several information returns come into play.

Schedule B, Part III

Part III of Schedule B asks whether you had a financial interest in or signature authority over a foreign financial account during the year. With a TFSA, the answer is yes. Check “Yes” on line 7a and list “Canada” on line 7b. Line 8 asks about foreign trusts; if you were a grantor of or transferor to one, indicate that here as well.¹⁰

Form 3520 and Form 3520-A

Because the IRS treats the TFSA as a foreign grantor trust, you are generally required to file Form 3520 (Annual Return to Report Transactions with Foreign Trusts) for any year in which you contribute to or withdraw from the account. You are also responsible for making sure Form 3520-A (Annual Information Return of Foreign Trust with a U.S. Owner) is filed every year the TFSA exists. A Canadian bank will not file 3520-A for you, so you typically complete and attach a substitute Form 3520-A to your Form 3520.¹¹

Penalties for missing these are severe. The initial penalty for Form 3520 is the greater of $10,000 or 35% of the gross value of property transferred to the trust or of distributions received. If Form 3520-A is not filed and you do not file a substitute, the penalty is 5% of the trust assets treated as owned by you.¹¹

FBAR (FinCEN Form 114)

If the combined value of all your foreign financial accounts, including the TFSA, exceeds $10,000 at any point during the year, file a Report of Foreign Bank and Financial Accounts.¹² The FBAR is filed electronically through FinCEN’s BSA E-Filing system, not with your tax return. It is due April 15, with an automatic extension to October 15 that requires no separate request.¹³

Form 8938 (FATCA)

Depending on the total value of your foreign financial assets, you may also need to file Form 8938 with your tax return. For U.S. residents filing single or married filing separately, the threshold is $50,000 on the last day of the year or $75,000 at any time during the year. For married couples filing jointly, the thresholds are $100,000 and $150,000. Higher thresholds apply to U.S. persons living abroad.¹⁴ Form 8938 and the FBAR are not interchangeable; meeting the threshold for one does not excuse the other.

The PFIC Trap for Canadian Mutual Funds in a TFSA

Canadian mutual funds and ETFs held inside a TFSA are generally classified as Passive Foreign Investment Companies under U.S. tax law. A foreign corporation is a PFIC if at least 75% of its income is passive or at least 50% of its assets produce passive income, and most Canadian pooled investment vehicles meet one or both tests.

The default PFIC treatment is harsh. Gains and excess distributions are taxed at the highest ordinary income rate (37% for 2025 and 2026), with no access to long-term capital gains rates, and the IRS adds compounded daily interest on the tax deemed deferred from prior years. Each PFIC requires its own Form 8621, so three Canadian mutual funds in a TFSA means three separate 8621 filings.

The practical result for U.S. persons: holding Canadian mutual funds or ETFs in a TFSA produces a uniquely bad outcome. None of the Canadian shelter, the highest U.S. rate on the gains, and heavy annual paperwork. Many cross-border advisors suggest U.S. persons either avoid PFICs in a TFSA altogether or hold only individual stocks and bonds that fall outside PFIC classification.

Tracking Your Own Cost Basis

Canadian financial institutions do not issue T-slips for TFSA activity, because nothing inside the account is taxable in Canada. U.S. persons therefore have to track their own cost basis for every holding. Every purchase, sale, dividend reinvestment, and return of capital must be recorded in U.S. dollars using the exchange rate on the transaction date.⁹

This is tedious and compounds year over year. A decade of contributions and dividend reinvestments across several holdings is difficult to reconstruct from scratch. A running spreadsheet built from day one is far easier than piecing statements together later. Brokerage transaction history and historical exchange rates from the Bank of Canada or xe.com are the raw materials.
