Corporate Income Tax - Net File

Effective July 8, 2011, Tax and Revenue Administration (TRA) offers Alberta corporate income tax filers the option of filing returns in electronic format.

Net File Eligibility Criteria

Any corporation that meets the following criteria will be eligible to net file its Alberta corporate income tax return:

  • the return has a valid Alberta Corporate Account Number,
  • the taxation year ends after December 31, 2007, and
  • the return being net filed is not an amended return.

Benefits of Net File

This filing method offers the following benefits:

  • Immediate confirmation – A confirmation number will be issued to you verifying that TRA has received your return.
  • Faster processing – Your return will be processed faster than a return sent through the mail. You will receive your Notice of Assessment and any refunds owed you by TRA sooner.
  • Cost savings – Filing in electronic format allows you to save the cost of handling, printing and mailing of paper returns.
  • Convenience – Extended hours of service will be available for submission of net filed returns.

Net File Certified Software

An electronic return in net file format can be submitted by a taxpayer or a service provider. There is no access code or registration required. However, the return must be generated and submitted using TRA-certified tax return preparation software. For a list of certified software offering net file capability, go to Software Certified for AT1 Net File Return Format for 2008 and Subsequent Taxation Years. Please refer to each software product for specific system requirements, instructions, and procedures on preparation and submission of returns in net file format.
