Requesting a reassessment of your T2 return

You can electronically transmit a request for a reassessment to your corporation income tax return using the latest commercial tax preparation software packages. You can also request a reassessment by sending your amended tax return in bar code format to your tax centre.

Otherwise, you can write a letter to the tax centre that serves the corporation. Clearly identify the following:

• the name of the corporation
• the corporation's business number (BN)
• the corporation's tax year
• any details that apply

With your letter, include any relevant supporting documents, such as:

• revised financial statements
• revised schedules

Requesting a carryback of a loss or tax credit

To ask to carry back a loss or tax credit to a prior tax year, file whichever of the following schedules apply:

• Schedule 4, Corporation Loss Continuity and Application, to ask to carry back a loss;
• Schedule 21, Federal and Provincial or Territorial Foreign Income Tax Credits and Federal Logging Tax Credit, to ask to carry back foreign tax credits on business income;
• Schedule 31, Investment Tax Credit – Corporations, to ask to carry back an investment tax credit; and
• Schedule 42, Calculation of Unused Part I Tax Credit, to ask to carry back a Part I tax credit.

You can file these schedules with the return on which you report the loss or earned the credit, or you can forward them separately to the tax centre that serves the corporation.
