Should I sum the witholding on my w-2 (US) as foreign tax paid in the "foreign slip" section? example: - [2] federal income tax witheld - [4] social security tax witheld

Hi,

When entering foreign taxes paid from the US you should include the following:

1. Social Security Tax Withheld

2. Medicare Tax Withheld

Do not enter the Federal Income Tax withheld as this is not your tax liability for Foreign Tax Credit purposes. You would need to use your tax liability as calculated on your 1040 or 1040NR (Your US income tax return for the same year) as well as any state income tax liability.
