IA 6: Restrictions on companies grouping tax losses
or “Rules for companies sharing tax losses within a group”

You could also call this:

“Special rules limit the use of certain types of tax losses”

You need to know about special rules for certain types of tax losses. These rules are different from the general rules that apply to most tax losses. Here’s what you need to know:

The special rules apply to:

  • Excess spending by investment funds
  • Losses from overseas companies (called attributed CFC net losses)
  • Losses from foreign investments (called FIF net losses)
  • Losses of mineral miners related to their mining areas
  • Losses of some types of investment companies (called multi-rate PIEs)

For each of these types of losses, there are specific rules about how they can be used. These rules are found in different parts of the tax law.

The special rules are designed to limit how these losses can be used, which is why they’re called “ring-fenced” losses. This means they can only be used in certain ways, unlike regular tax losses which have fewer restrictions.

If you have one of these types of losses, you’ll need to look at the specific rules that apply to that type of loss. The general rules for tax losses don’t apply in these cases.
