My wife is Canadian but US citizen now retired and has CPP and OAS reported on the NR4 forms. I have never seen a 1099-OAS or any other 1099 related to either. She gets the NR4's but they are in CAD so of little use other than a record of the CAD benefits. I just keep track of the monthly direct deposits to our US checking acct and add them up at the end of the year since they are in US funds so it eliminates having to try to figure out an exchange rate to use. You would think by now, the Canadian govt could simply show the total they deposited in US funds on the form and you would also think by now the IRS would have a separate line item for these. or at the very least, point out that the US amounts received are to be added in.
Someone once told me on these forums to just claim 85% of the total but they never explained which total or why 85% since at that time the exchange rate was well over 15%. Over the past few years the exchange rate often varies quite a bit from month to month so the only logical solution seemed to me to just track the deposits.
