How to Obtain a CRA Web Access Code (WAC) for T2 Corporation Internet Filing in Canada

If you’re filing a T2 corporate tax return online in Canada, you may need a Web Access Code (WAC) from the Canada Revenue Agency (CRA). This code is required for submitting your T2 Corporation Income Tax Return through the CRA’s Corporation Internet Filing service.

In this guide, you’ll learn what a Web Access Code is, why it’s required, how to get one, and what information you’ll need before contacting the CRA.

What Is a CRA Web Access Code (WAC)?

A Web Access Code (WAC) is an 8 digit security code issued by the CRA that allows corporations to securely submit their T2 corporate income tax returns online using certified tax software.

The WAC is used specifically for:

  • CRA Corporation Internet Filing

  • Electronic filing of T2 returns

  • Authorized business tax submissions

Without a valid Web Access Code, your corporation may not be able to complete online filing through CRA approved software.

Who Needs a Web Access Code?

You may need a CRA Web Access Code if:

  • You are filing a T2 corporate tax return online

  • You are using certified tax software

  • Your corporation has not previously received or stored a WAC

  • You are filing for a new corporation

  • Your previous WAC is lost or expired

Most incorporated businesses in Canada that e-file directly with the CRA will require this code.

Choose the Right CloudTax T2 Filing Option

A WAC code is only needed when you are completing and submitting your T2 corporate tax return yourself.

For do-it-yourself T2 filing, use CloudTax T2 Basic: https://www.cloudtax.ca/t2-basic

If you prefer a done-for-you corporate tax service where CloudTax prepares and files your return from start to finish, visit: https://www.cloudtax.ca/corporate-tax

With the done-for-you service, a WAC code is generally not required from your side because the filing is handled for you.

Information You Need Before Contacting the CRA

Before requesting your Web Access Code, make sure you have the following information ready:

1. Business Number (BN)

You’ll need your corporation’s 9 digit Business Number assigned by the CRA.

Example:

  • 123456789RC0001

2. Corporation’s Fiscal Year End

The CRA will ask for your corporation’s fiscal year end date to verify your identity and locate the account.

Example:

  • December 31, 2025

  • March 31, 2026

Having this information prepared helps speed up the process.

How to Obtain a CRA Web Access Code

To get your Web Access Code, contact the CRA’s business support line.

CRA Phone Number for Web Access Codes

Call: 1-800-959-2803

The CRA representative will verify your corporation’s information and issue an 8 digit Web Access Code over the phone.

Processing Time

In most cases, the process takes approximately 5 to 10 minutes.

This CRA line is usually much quicker than the regular CRA phone support lines, so obtaining a WAC code is often a fast process.

Once issued, you can immediately use the code to submit your return electronically.

How to Generate a WAC Code for T2 Filing

If you are filing your corporate tax return through CloudTax, you can generate your WAC code directly inside the platform.

The CloudTax WAC Generator helps create the authorization needed for CRA electronic filing.

Once entered, your T2 return can be submitted directly to the Canada Revenue Agency.

Even if you are a first time corporate tax filer and do not yet have a Notice of Assessment (NOA), you still need a WAC to file your T2 return electronically. In this case, you should call the CRA to obtain your Web Access Code.

What If the WAC Generator Does Not Work?

In rare situations, the WAC code may produce an error.

If that happens, the fastest solution is to contact the CRA Business Enquiries line at:

1-800-959-2803

The CRA can manually verify your business information and issue a valid Web Access Code during the call.

Where to Enter the Web Access Code

When you are ready to submit your T2 return through CloudTax, the platform will prompt you to enter your 8 digit Web Access Code.

Once the code is entered, your return can be submitted electronically to the CRA.

The WAC acts as authorization for secure online filing.

Benefits of Corporation Internet Filing

Using CRA Corporation Internet Filing provides several advantages:

Faster Processing

Electronic submissions are processed faster than paper returns.

Immediate Confirmation

You receive instant confirmation that the CRA received your return.

Reduced Errors

Tax software helps minimize calculation and filing mistakes.

Secure Submission

The CRA’s encrypted filing system helps protect business tax information.

Common Questions About CRA Web Access Codes

Is the Web Access Code the same as a CRA My Business Account password?

No. A Web Access Code is specifically for Corporation Internet Filing and is separate from CRA login credentials.

Can accountants obtain the code for clients?

Yes, authorized accountants or tax preparers can contact the CRA on behalf of the corporation if they have proper authorization.

Does the code expire?

The CRA may issue new codes periodically or require verification if information changes.

Can I file without a WAC?

If you are filing the T2 return yourself through tax software, you will generally need a WAC. If you are using a done-for-you filing service where professionals file on your behalf, the process may be handled for you.

Tips for a Smooth T2 Filing Process

Before filing your corporation return online:

  • Verify your Business Number is active

  • Confirm your fiscal year end

  • Use CRA certified tax software

  • Keep your Web Access Code secure

  • File before the corporate tax deadline

Staying organized can help avoid delays and CRA follow ups.

Final Thoughts

Obtaining a CRA Web Access Code is a straightforward process that helps corporations securely file T2 tax returns online.

By preparing your Business Number and fiscal year information in advance, you can usually receive your code within minutes by contacting the CRA.

Whether you are filing your own T2 return using CloudTax or working with a professional corporate tax filing service, understanding how the CRA Web Access Code works can help make the filing process faster and smoother.
