The details for line 12, reduction of foreign taxes is described in the f1116 instructions starting on p. 17.

Line 12 has specific items listed. You may have to reduce the foreign taxes you paid or accrued by the following items.

• Taxes on income excluded on Form 2555.
• Taxes on income from Puerto Rico exempt from U.S. tax.
• Taxes on income from American Samoa excluded on Form 4563.
• Taxes on combined foreign oil and gas income.
• Taxes on foreign mineral income.
• Reduction for failure to file Form 5471
• Reduction for failure to file Form 8865.
• Reduction of taxes or credit due to international boycott operations.
• Taxes related to a foreign tax credit splitting event.

These are fairly uncommon and would be noted on any document that you receive.
