Final answer:
To avoid double taxation on foreign investment income, Stanley may be eligible to claim the foreign tax credit.
Step-by-step explanation:
To avoid double taxation on income earned from foreign investments, Stanley may be eligible to claim the foreign tax credit.
The foreign tax credit is a tax credit given to individuals or businesses to offset taxes paid to a foreign country on income earned from investments in that country.
By claiming the foreign tax credit, Stanley can reduce his tax liability in his home country by the amount of taxes already paid to the foreign country, therefore avoiding double taxation.
