Corporate tax

Most Canadian corporations are required to file a corporate income tax return for each taxation year in which they exist, even if they have no tax liability for that year.

Every year, many companies are faced with countless documents to complete. The task can be complex, to say the least!

When it comes time to submit tax returns, it is important to send your documents to the right destination. But where exactly do you find the address of the tax office for your corporate income tax return?

Read our tips to make sure you send your tax documents to the right place!

How to send your corporate tax returns to the tax authorities

When it comes to filing provincial and federal corporate income tax returns, respecting the mailing date and choosing the right address to send them to are prerequisites for all Quebec and Canadian businesses.

There are two ways to file your corporate income tax return:

  • By mail
  • Online

Although not as practical or fast as online, the paper solution is still a very popular alternative for businesses. In fact, paper forms are still used by many business owners in Quebec. However, you must know exactly where to send it to ensure that it is received by the authorities.

Where should you send your business tax return?

Finding the right address to send your return depends on your location in Canada. The destination address will be different depending on your location. You will be asked not to make a mistake when sending your return or you may be subject to penalties due to late taxes.

To find the address of your collection office, simply visit the Canada Revenue Agency and Revenue Quebec websites to find out where to send your T2 returns and CO-17 returns. You can also obtain all the information you need to send your return by picking up a guide at your nearest post office or Service Canada office.

When sending your returns, be sure to choose the right documents for your province!

How to file your corporate income tax return online

For the paper return hardliners, you should know that if your gross annual income exceeds one million dollars, Revenu Québec and the Canada Revenue Agency require you to use an online solution. And if, like many people, you are not familiar with the Web, a corporate tax specialist can assist you with your corporate taxes and even take care of sending your returns online.

Filing a company's tax return online can be done in three different ways:

1. Personally handle the registration using a software program

You can register your company on the ClicSÉQUR site free of charge to file your corporate income tax return online. However, you will have to use an authorized software to file your return. Find out in advance which software is authorized by the Canadian government to ensure that it is accepted.

2. Use a proxy preparer

If you don't want to do this on your own, you can hire a tax preparer who will transmit the report using their own or the company's ClicSÉQUR user code.

They will use the EFILE service: Electronic Filing. However, you will need to provide them with a power of attorney to certify this choice.

3. Use a licensed preparer without a power of attorney

Finally, you can also choose the services of an authorized preparer. The preparer will transfer your application using their ImpôtNet Québec access code. In this case, you do not need a power of attorney since you can pre-fill out the transmission form and send it directly to the preparer.

Also note that since 2013, preparers who file more than a dozen corporate tax returns per year must file solely via the Internet.
