Does California or New York tax my Indian income?
Yes. If you are a tax resident of a state with an income tax, that state taxes your worldwide income, and your Indian interest, dividends, rent and capital gains are part of it. State residency is its own test, usually built on where your home and life are, and it is settled separately from your federal filing.
Once you are a resident of California, New York or New Jersey, the Indian income lands on the state return too. California and New York start their computation from your federal income, so it flows straight through. New Jersey reaches the same place by its own route, taxing a resident's worldwide income under its own gross-income categories. Either way, the same Indian gain or rent is taxed three times over: by India, by the US federal government, and by your state. The two federal-level reliefs you rely on, the treaty and the foreign tax credit, mostly do not reach the state layer. That is the layer the treaty and the credit were never built to cover.
Why the India-US treaty does not help at the state level
The India-US tax treaty binds only US federal tax, not your state. Its taxes-covered article, Article 2, lists the taxes it applies to on the US side as the federal income taxes imposed by the Internal Revenue Code. State and local income taxes are not on that list. A US state is a separate taxing authority and is not a party to the treaty, so a treaty rate cap or a treaty exemption you claim on your federal return has no automatic effect on your state return.
California goes further and effectively disregards tax treaties for individual residents. A position that lowers your federal tax under the treaty does not lower your California tax. So if you were counting on a treaty rate to hold your Indian income down, that cap protects the federal layer only. The state taxes the income on its own rules, at its own rate, as if the treaty were not there.
The bigger sting: no state credit for the Indian tax
Even where the treaty is silent, you would expect a foreign tax credit to stop the double tax. At the state level, for most states, there is none. The federal foreign tax credit on Form 1116 is a federal credit, and it can offset much or all of your federal tax on Indian income. States are not required to offer an equivalent, and the big diaspora states do not.
| State | Credit for the Indian tax? |
|---|---|
| California | No, and it disregards the treaty |
| New Jersey | No credit for tax paid to any foreign country |
| New York | Only for another US state or a Canadian province, not India |
| Texas, Florida, Washington | No state income tax, so nothing to pay |
California and New Jersey give no credit for foreign tax at all. New York gives its resident credit only for tax paid to another US state or a province of Canada, which does not include India. So the Indian tax you paid does nothing against the state charge, and the state tax stacks on top in full.
How much this costs: Karthik in San Jose
Karthik is a US citizen in San Jose. He sells a long-held Indian property and books a long-term gain of about 200,000 dollars.
India taxes the gain at 12.5% without indexation for an NRI, plus surcharge and cess, roughly 14.95%, about 29,900 dollars. On his federal return, the foreign tax credit offsets much of the federal tax on the same gain, so the federal layer comes out close to neutral.
California is where it hurts. It taxes capital gains as ordinary income, with no preferential rate, and gives no credit for the 29,900 dollars of Indian tax. At his marginal California rate of about 9.3%, the state takes roughly 18,600 dollars on the same gain. Had Karthik realised the sale while resident in Texas or Florida, states with no income tax, that 18,600 dollars would have been zero. The California layer is pure extra cost that neither the treaty nor the Indian tax can touch.
What actually reduces the state bill, and what does not
Two things move the state number, and one popular move does not. First, an accurate cost basis. The state taxes the gain figure that flows from your federal return, so if your Indian cost, improvements and currency conversion are documented correctly, the US-computed gain is not overstated, and the state taxes a smaller, correct figure. Getting that basis right is India-side work.
Second, timing against your state residency. The state tax follows where you are resident in the year you realise the income, so selling an Indian asset in a year you live in a no-income-tax state, or before you establish California residency, or after you leave it, can remove the state layer entirely. That is a call to plan before the sale, not after.
What does not help is an Indian reinvestment exemption like Section 54. It can cut your Indian tax, but the US and the state compute the gain on their own rules and ignore Section 54, so it does nothing for the state bill and can even leave less Indian tax for the federal credit. Weigh it with the whole picture in view.
