If you choose to exclude foreign-earned income, you can’t take a foreign tax credit or deduction for taxes on income you can exclude.

Foreign Earned Income and Housing Exclusions

You may not take either a credit or a deduction for taxes paid or accrued on income you exclude under the foreign earned income exclusion or the foreign housing exclusion. There's no double taxation in this situation because that income isn't subject to U.S. income tax.
