Rules and decisions to review
- Individuals generally use Form 1116 unless a specific exception permits claiming the credit without it.
- Whether a tax qualifies depends on its legal character and other rules; a foreign sales tax or social contribution is not automatically an income tax credit.
- The credit limitation depends on foreign-source taxable income and separate income categories. Unused credits may have carryback or carryforward treatment under the applicable rules.
- Foreign taxes attributable to income excluded under the foreign earned income exclusion cannot also generate a credit.
A practical example
If some overseas wages are excluded and some remain taxable, the related foreign tax cannot simply be claimed in full. The preparer must allocate taxes and test the remaining eligible credit.
Records to gather
Gather foreign assessments, payment receipts, withholding certificates, income-category records and prior-year credit carryovers.
Your next step
Separate foreign income by category and match each tax payment to the income and year involved. Ask how the credit limitation, prior carryovers and any exclusion affect the amount actually claimable.
