My client in a US national living and working abroad. He earned from employment (w2) $3,590. He is filing jointly and has social security income of $16,425 (excluded). Therefore, the total income and AGI is $3503.90. When I add Form 2555 for foreign earned exclusion, the total income (line 9, 1040) then becomes negative (-3,590). The software does not permit e-file since there is no income. Would it make sense to leave out the Form 2555 (foreign earned income exclusion)? Should I paper file. Any suggestions please?
