Companies with a permit for exploration or exploitation of resources in Greenland can carry forward tax losses without time limitations. These carried forward tax losses can be applied to offset future taxable income but are subject to limitations in the case of an ownership change. It is important to note that tax losses cannot be carried back to previous tax years to offset past income.

This allows resource companies to manage periods of significant investment and low profitability by reducing future tax liabilities once they become profitable. However, restrictions related to ownership changes help prevent companies from exploiting the carryforward rules unfairly during acquisitions or mergers.
