In order to claim a deduction you must substantiate the deduction (e.g. receipts for purchases). The Internal Revenue Service does have a uniform sales tax table for those who do not keep records.
If state taxes were deducted from your Social Security, pensions, and retirement accounts, then you may claim those taxes as a deduction. If you did not pay sales or local taxes, then you cannot take the default deduction. It is best to claim the state income tax deduction.
However, if you paid foreign income taxes, then you may be able to take a credit for paying those taxes by utilizing the Form 1116 Foreign Tax Credit

- Type foreign tax credit in Find
- Click the Jump to foreign tax credit link
Begin navigating through the prompts, it will give you options on how to claim the credit.
