@sulz assuming you are US citizen/Resident,
1. Your transferring of US$100K will result in SAR being raised as a routine matter but it is not a tax event and nothing else is notable in this transaction. ( you probably told your US bank that is is to buy property in India )
2. The amount resting in an account (in India ) that you have control ( signature authority and/or own/operate) will require you to file FBAR form ( FINCEN for 114). This is because this will mean that your account value is equal to /more than US$ 10,000 at sometime during the tax year.
3. Depending on your filing status ( single/ married ) you may also come under FATCA and therefore report owning a bank account / financial assets in a foreign bank -- this is form 8938 along with your tax return. Again this is not a tax even , just reporting requirement.
4. Depending on the use of the property you may have to file a schedule-E with your return , if you rent out the property during a tax year.
5. If you received a gift from a foreign person/estate of more than US$100,000, you have to file a form 3520 -- not a tax even but reporting is required. If you gave a gift to someone , more than the free amount per year per person, then you have to report a gift return form (form 706 )-- not a tax event NOW but counts towards your life time tax free amount.
Is there more I can do for you ?
Namaste
