ITIN application for mother in law
Hi,
Greetings!
I applied for my 2020 taxes married filing jointly. My mother-in-law meets the Substantial Presence Test for the year 2020 and 2021 (using 3 year past data). We did not realize that we could claim her as a dependent. Now that I try, I realized that she doesn't have an ITIN. We are applying for ITIN with W7. She is Indian citizen with green card paperwork in progress. Her income in India is primarily bank interest and is ~$2500.
Questions:
1. Do we submit W7 with her form1040 only then once we get her ITIN we submit our form1040 amended OR do we submit W7 with her form1040 and my form1040 amended with her claimed as a dependent and ITIN left blank?
2. She has no paperwork (i.e. 1099-MISC/INT etc) from US institutions. She has no account in any US bank / brokerage etc. In her form1040, on which line does her $2500 income go? If line 8 of form1040, then would Schedule1 line 8 will also be $2500? I ask because I could not find an appropriate category for line 8 of Schedule 1 on Page 87-90 of IRS' document i1040gi.pdf for her income in India.
2b. I have her Indian tax summary page 1 showing the amount in INR (currency) (IN HINDI though, not in English). Do I need to file it with her taxes? If not, what does she submit to show her ~$2500 income proof?
3. I assume that line 12 for married filing separately (her) would result in $12400 which will result in $0 taxable income hence $0 taxes. Is that correct?
4. Is there an income limit below which a dependent has to have income?
Please comment and help!
Thanks
