How to report foreign social security when there is no tax forms from Croatia, they just don't issue any. Checking around got several different options: to make substitute 1099-R OR add it to Sch 1 , under 8-z and describe what it is OR under Other reportable income. I assume there are many people in same situation and it's strange that there's no directions for it, when there's no Treaty with USA . I've read several advises from different communities and there are always several options. I do understand that reported income will be the same and taxed the same if filed on any of those substitute Forms but it would be nice to know what is CORRECT way. Also, if filing manually and mail tax return it's again an issue as there's no form to fill anyway! Thanks
