Foreign tax withheld from an invoice is not automatically a usable U.S. foreign tax credit. The levy must meet the applicable creditability rules, and source, category and limitation rules affect utilization. A refund or treaty remedy abroad may need consideration; paying a foreign tax does not itself make the income foreign-source for U.S. purposes.

A specific business-owner situation

A U.S. consulting firm performs work in its U.S. office, but its foreign customer withholds local tax. The owner assumes the full withheld amount can reduce U.S. income tax.

Illustrative example, not a client result.

What to establish before filing

  1. Identify the legal tax and obligated taxpayer.
  2. Determine U.S. source and credit category.
  3. Review limitation treaty and foreign refund procedures.

Which fact changes the answer?

Foreign-source income and a treaty resourcing provision can change the limitation analysis. The customer's country alone does not establish either.

A mistake to avoid

Do not claim a credit from the customer's short payment without evidence of the tax imposed.

Records that support the decision

  • Withholding certificate.
  • Foreign tax law and invoice.
  • U.S. sourcing and limitation workpaper.

The decision to document

Evaluate credit deduction or foreign recovery options using the entity's and owners' actual tax positions.
