US citizen spouse residing abroad is filing Married Filing Separately. Spouse of US citizen is non-resident alien (NRA) with no SSN or ITIN, who has no US source income. Both spouses are over 65. Turbo Tax is showing increased standard deduction for both spouses based on age: $12,550 + $1,350 + $1,350 = $15,250. Is NRA spouse eligible for the additional $1350 deduction amount if that spouse has no SSN/ITIN? Or is the correct standard deduction $13,900?
