Are there any tax implications if a person with EAD & on L2 is working for Indian company & getting paid in Indian rupees.

Yes, you are authorized. Yet, any person who lives in the U.S. for more than 183 days is usually considered a tax resident for taxation purposes. It does not matter if they are a permanent resident, unlawful immigrant, or visa holder.

All income earned in the U.S. can be subject to U.S. Tax Laws. How they handle their taxation is a tax question best discussed with an experienced CPA or tax attorney.

The above is general information not meant to be legal advice. The above reply does not create an attorney-client relationship.
