Do You Need an EFILE Number to Use CloudTax EFILE Software?

CloudTax requires a CRA EFILE number for T1 personal returns, but lets tax professionals submit T2 corporate returns directly to CRA using a WAC code while waiting for EFILE approval.

Written by Arani Tharmalingam

If you are an accountant or tax professional using CloudTax EFILE Software, one of the most common questions is whether you need a CRA EFILE number before you can start filing tax returns electronically.

The answer depends on the type of tax return you are filing.

For T1 personal tax returns, you do need a CRA EFILE number. However, for T2 corporate tax returns, CloudTax provides an alternative option that allows you to file using a WAC code even if your EFILE number has not been issued yet.

This flexibility helps accounting firms and tax professionals begin filing corporate returns faster without unnecessary delays.

Do I Need an EFILE Number for T1 Personal Tax Returns?

Yes.

To electronically file T1 personal tax returns through CRA using CloudTax Tax Software, you must have a valid CRA EFILE number.

Your EFILE number is issued by the Canada Revenue Agency after your EFILE application has been approved. This authorization allows accountants and tax preparers to electronically transmit personal tax returns on behalf of clients.

Requirements for T1 EFILE Submission

To file T1 personal tax returns electronically, you generally need:

  • A CRA-approved EFILE account

  • Your CRA EFILE number

  • Authorization to electronically transmit returns

  • Professional tax software such as CloudTax

Without an EFILE number, CRA will not allow electronic filing for T1 personal tax returns.

Can I File T2 Corporate Tax Returns Without an EFILE Number?

Yes.

One of the advantages of using CloudTax Corporate Tax Software is that tax professionals can submit T2 corporate tax returns using a WAC code.

This means you can continue filing T2 returns electronically even if you are still waiting for CRA to approve your EFILE application.

What Is a WAC Code?

A WAC code (Web Access Code) is provided by CRA for specific electronic filing activities related to corporate tax submissions.

The WAC code option allows authorized tax professionals to transmit T2 corporate tax returns directly to CRA without requiring a traditional EFILE number for the submission process.

This gives firms additional flexibility and helps avoid delays in serving corporate clients.
