How to Register a Trust with the CRA for Ontario Residents

To register a newly created family trust in Ontario, you must apply for a Trust Account Number (TAN) from the Canada Revenue Agency (CRA). Under Bill C-15 (enacted in March 2026), bare trusts are exempt from filing T3 returns for the 2025 tax year, with reporting postponed to tax years ending on or after December 31, 2026. For family and express trusts, significant exemptions from T3 and Schedule 15 filings now apply depending on asset value and ownership structure.

Setting up a family trust is a highly effective way to manage wealth, protect assets, and plan your estate for the next generation. However, simply drafting and signing a legal document is not the end of the journey. In Ontario, any resident creating a trust must strictly comply with Canada Revenue Agency (CRA) regulations. The CRA treats a trust as a separate taxpayer, which means it needs its own identification number and annual tax filings, even if it does not generate immediate income.

Following the enactment of Bill C-15 (Budget Implementation Act, 2025, No. 1) in March 2026, the CRA’s trust reporting requirements have been significantly amended to narrow the compliance burden. While rigorous beneficial ownership reporting rules apply, bare trusts are entirely exempt from T3 and Schedule 15 reporting for the 2025 taxation year, with requirements postponed to tax years ending on or after December 31, 2026. Furthermore, Bill C-15 introduced key exemptions for low-value express trusts and certain family trust arrangements. Understanding how to properly navigate these rules is critical to avoiding unnecessary compliance costs while remaining legally secure.

Step-by-Step Process to Register a Trust in Ontario

Registering a trust with the CRA requires careful attention to detail and precise timing. Generally, most Ontario residents work alongside a tax accountant or an estate lawyer to ensure these steps are completed flawlessly. Here is the standard process for setting up your trust’s tax profile.

Step 1: Finalize the Trust Agreement

Before you can deal with the CRA, your trust must legally exist. 🖊 You will need a formally drafted and signed Trust Agreement. This legal document outlines the settlor (the person creating the trust), the trustees (those managing it), and the beneficiaries (those who receive the assets). Often, a traditional silver coin or a $10 CAD bill is attached to the agreement to represent the initial settlement of the trust property under Ontario common law.

Step 2: Apply for a Trust Account Number (TAN)

Just as a person has a Social Insurance Number, a trust needs a Trust Account Number. You or your authorized representative must apply for a TAN through the CRA. The fastest method is using the CRA’s online “Trust Account Registration” portal via My Account or Represent a Client. You will need to provide basic details, such as the trust’s name, the date of creation, and the mailing address in Ontario.

Step 3: Gather Beneficial Ownership Information

Under current CRA regulations, transparency is mandatory. 👥 You must gather detailed information about every person connected to the trust. This includes the legal names, addresses, dates of birth, and tax identification numbers of the settlor, all trustees, all beneficiaries, and anyone who has the power to exert influence over trustee decisions (such as a protector). You will need this data for Schedule 15 of your T3 return.

Step 4: Prepare the Initial T3 Return

The T3 Trust Income Tax and Information Return is the core tax document for your trust. Under Bill C-15, certain trusts are exempt from filing a T3 return and completing Schedule 15. Specifically, express trusts holding under $50,000 CAD in assets throughout the year are exempt. For family-held trusts (where all trustees and beneficiaries are relatives), there is an exemption from Schedule 15 (and T3, if no tax is payable or assets sold) if the total fair market value does not exceed $250,000 CAD and the trust only holds basic assets like cash, GICs, or mutual funds. If these exemptions do not apply, the return is due no later than 90 days after the trust’s tax year-end.

Step 5: File with the CRA and Maintain Compliance

Once the T3 return and the mandatory Schedule 15 are completed, they must be submitted to the CRA. 📬 You can file electronically using certified tax software or mail physical copies to the designated CRA tax centre for Ontario residents. Moving forward, trustees have a legal duty to maintain accurate financial records and file a T3 return annually, keeping all banking and investment records organized for at least six years.

How Much Does it Cost in Ontario?

While registering with the CRA is technically free, the professional assistance required to do it correctly involves expenses. Here are the typical costs associated with establishing and registering a trust in Ontario.

ServiceEstimated Cost (CAD)Details
CRA TAN Registration$0The CRA does not charge a fee to issue a Trust Account Number.
Law Firm (Trust Drafting)$2,500 – $5,000+Legal fees to draft the complex Trust Agreement and establish the entity in Ontario.
Accountant (T3 Filing)$1,000 – $3,000Annual accounting fees to prepare the T3 return and beneficial ownership schedules.
Late Filing Penalties$25 per dayCRA penalties for late T3 filing, up to a maximum of $2,500 CAD (or much higher for gross negligence).

How Long Does the Process Take?

Timing is a critical factor when dealing with tax authorities. Applying for a TAN online is relatively quick; you can often receive your number instantly or within 1 to 2 weeks if the CRA requires further manual review. If you apply by mail, expect the process to take 4 to 8 weeks.

Preparing the actual T3 return depends on the complexity of your trust’s assets. ⌛ Generally, accountants require 2 to 4 weeks during tax season to finalize the paperwork. Remember that the absolute deadline to file the T3 return is exactly 90 days after the trust’s tax year-end. Missing this deadline triggers immediate financial penalties.

Frequently Asked Questions (FAQ)

Do I absolutely need a lawyer to register a trust?

While you can technically apply for a TAN yourself, drafting the foundational Trust Agreement requires a lawyer. Furthermore, most trustees rely on a specialized accountant to ensure the CRA filings are completely accurate.

What happens if I forget to file the T3 return?

The CRA imposes strict penalties if a required return is not filed. The standard penalty is $25 per day, up to $2,500. However, if the CRA determines you knowingly failed to file required beneficial ownership schedules, the penalty can jump to 5% of the highest value of the trust’s assets (minimum $2,500). Fortunately, under Bill C-15, if your trust falls under one of the new statutory exemptions, no annual filing is required, shielding you from these penalty risks completely.

Do bare trusts need to be registered in Ontario?

Under Bill C-15, the rules for bare trusts have been substantially relaxed. For the 2025 tax year, the CRA has officially waived the requirement for bare trusts to file a T3 return or Schedule 15. Filing requirements are postponed to taxation years ending on or after December 31, 2026. Furthermore, Bill C-15 introduced permanent exemptions starting in 2026, meaning many common bare trusts (such as those holding assets under $50,000, joint spousal convenience accounts, or where parents are on title solely to secure a child’s mortgage) will never have to file a T3 return.

Can I use my personal CRA My Account for the trust?

No. A trust is considered a separate entity. However, as the primary trustee, you can link the trust’s TAN to your CRA Represent a Client portal to manage its filings digitally.
