Foreign tax credit paid or accrued
I live abroad and am trying to figure out Form 1116, the Foreign Tax Credit Form. I am not sure if I should count taxes as "paid" or "accrued". My taxes are withheld from my payslip. However, just as in the USA, too much or too little can be withheld, so I could end up paying more or receiving a refund later.
According to the instructions on page 2 of Form 1116, I have to attach a detailed explanation of how I figured the conversion rate for the foreign currency. However, also according to the instructions, if I use the "paid" method I would have to use the exchange rate in effect on the date when I paid the taxes. How can I do that when the taxes were withheld throughout the year? If I use the accrual method I can use the average exchange rate for the year, just as I do for the rest of my tax return (for my income, etc.).
If I do have to use the paid method, how can I determine the exchange rate? What do I write in my "detailed explanation" of how I figured the conversion rate for the foreign currency?
Thanks.
