Specifically referring to whether i repeat my income in Part III Foreign Tax Credit Computation 12. Reduction in foreign taxes: a (1) current year foreign earned income excluded less related deductions and (2) Total FEI less related deductions
From TT's guidance:
Lines 12a1 through 12a5:
If you excluded some or all of your foreign income on Form 2555, Foreign Earned Income Exclusion, the foreign taxes you paid must be reduced by the amount of taxes that relate to the foreign earned income that has been excluded on Form 2555. Lines 12a1 through 12a5 are used to determine the allocation ratio to be used in apportioning the amount of taxes applicable to excluded income.
The program performs the computations on lines 12a3, 12a4, 12a5 only for the General category of foreign income (i.e., if box b is checked at the top of this worksheet). Lines 12a1 and 12a2 must be entered when applicable.
If you excluded foreign income on Form 2555, enter on line 12a1 the amount of foreign earned income excluded (Form 2555, line 45) reduced by any itemized deductions that relate to the foreign income excluded.
Enter your total foreign earned income for the year on line 12a2. This is the total foreign earned income from Form 2555 (both copies), line 26, reduced by deductible expenses allocable to that foreign earned income.
