Deductions & credits

Foreign Social Security Retirement Income also called Foreign Social Security Pension must be reported in Form 1040 line 8 referred to “Other income from Schedule 1 line 8 z”. Unless a bilateral treaty exists to avoid double taxation, Foreign Social Security Pensions are fully taxable because of the very well known “saving clause “. 
So, don’t make the mistake to report it neither in line 5b) nor in line 6 b) . 
I do hope this will help you . Any comment from anyone will be appreciated and will enrich our network.
