T3010 deadline: when it is due and what to do if it is late

Calculate the date

Add six months to the charity’s fiscal year-end:

Fiscal year-end	T3010 due date
December 31	June 30 of the next year
March 31	September 30
June 30	December 31
August 31	February 28 or 29

Confirm the fiscal year-end on CRA’s records. Revenue, assets, and inactivity do not change the deadline.

Preserve proof of filing

Keep the complete return and schedules, authorized approval, electronic confirmation or delivery evidence, and the working papers tying the return to the records. A delayed processing status should be investigated, but it does not by itself prove a timely electronic filing was late.

If the deadline has passed

1. Confirm whether the return was already submitted and locate the confirmation.
2. If not, complete and file it promptly.
3. Review the charity’s CRA correspondence and online account for a notice.
4. Correct the records and governance process that caused the delay.
5. Obtain advice if a notice of intention to revoke, revocation, penalty, or material misstatement is involved.

Do not wait for a voluntary-disclosure analysis before filing a clearly overdue return unless professional advice for the specific facts supports that approach.

Voluntary Disclosures Program

The VDP changed effective October 1, 2025. An application must still meet all five eligibility conditions:

1. It is submitted before an audit or investigation has been initiated against the taxpayer or a related taxpayer in respect of the information being disclosed.
2. It includes all relevant information and documentation for the required tax years or reporting periods.
3. The information includes an error or omission with applicable interest charges or penalties.
4. The information is at least one year, or one reporting period, past the filing due date.
5. It includes payment of the estimated tax owing, or a requested payment arrangement subject to CRA approval.

What changed is the relief structure. Being contacted by CRA no longer disqualifies an application by itself:

• An unprompted application — no prior communication about an identified compliance issue, or one made after only a general education letter — is normally considered for general relief: 75% relief of applicable interest and 100% relief of applicable penalties.
• A prompted application — made after CRA has raised a specific error, omission, or correction deadline, or after CRA received third-party information — is normally considered for partial relief: 25% relief of applicable interest and up to 100% relief of applicable penalties.

An application is still not voluntary once an audit or investigation has begun, and in the VDP context that is not limited to CRA — it includes a law enforcement agency, securities commission, or other regulated authority.

A basic late-filing fact pattern does not automatically qualify or require VDP treatment.

If registration is revoked

Revocation ends authority to issue official donation receipts. The organization may have to file Form T2046 and address the revocation tax. Re-registration is a separate process and should not be described as automatic. Use current CRA guidance and obtain legal and tax advice.
