One umbrella, six areas of practice
International taxation covers every tax matter touching more than one country, India dealing with foreign entities, or foreign entities dealing with India. The goal is always the same: make sure income isn't taxed twice, compliance is met in every jurisdiction involved, and every treaty or legal benefit available is actually claimed, not left on the table.

Mistakes we see most often
Treating It As an Afterthought
Cross-border tax planned after the transaction, instead of before it, when far fewer options remain.
Missing Procedural Requirements
Being technically eligible for a benefit but missing the TRC, Form 41, or Form 145/146 that's needed to actually claim it.
DIY Treaty Interpretation
Small differences in treaty article or fact pattern change the outcome entirely, this is rarely a safe area to self-serve.
No Documentation Ready
Cross-border filings get more scrutiny, not less. Documentation gathered after a notice arrives is a much harder position.
What happens if this isn't handled correctly
- →Double taxation, blocked refunds, penalty and interest
- →Compliance notices and prolonged litigation
- →Cash flow issues from excess TDS sitting unclaimed
- →Reputational and legal risk on future cross-border dealings
One team, the full spectrum
Most firms specialize in one piece, treaty advisory, or compliance, or NRI filing. We cover DTAA, withholding tax, NRI taxation, and foreign company compliance together, as one coordinated practice, so nothing falls through the gap between two advisors.
We focus on practical, deadline-driven execution, not just advisory opinions, with a track record across the US, UK, UAE, Singapore, and other major treaty jurisdictions.
