The 2026 filing season is fast approaching! If you plan to volunteer at a free tax clinic again this year and wish to transmit returns electronically, you must renew your EFILE account online.

The EFILE suitability screening process will only begin once you have completed your volunteer registration and submitted your EFILE renewal application. You will receive an email or a letter to advise you of the result of the screening process. This process is normally completed within 30 business days of the CRA receiving an online registration or renewal application form.

However, it is important to note that some applications may take longer to process due to circumstances that are outside of the CRA’s control, such as but not limited to: an applicant’s failure to file an income tax return, failure to comply with a requirement to pay, collect or remit taxes, and complex applications.

Please submit your renewal as early as possible to avoid unnecessary delays. To ensure that your application is processed before the start of the next filing season, we encourage you to submit your application before January 12, 2026.
