The IRS does not allow a direct deposit of a refund into a foreign bank account. Qualified accounts are accounts held by financial institutions within the United States and established primarily for personal, family, or household purposes. Qualifying institutions may be national banks, state banks (including the District of Columbia and political sub-divisions of the 50 states), savings and loan associations, mutual savings banks, and credit unions.
