These entries describe how a term works rather than what it is worth in a given year. That is deliberate — figures move, and a figure remembered from a definition is the kind that ends up on a return unchecked.
Terminology is where cross-border risk hides. The rate is visible and gets checked; the classification is invisible and does not, which is why the classification is what usually goes wrong. Every entry closes with the filings it touches, because a definition you cannot attach to a form is not yet useful.
Recognising a term like this in your own paperwork is the useful skill. Working out which side of it you fall on is a short call. Every page here carries the name of the person who reviewed it and the date they did.
- Unilateral relief — Relief for foreign tax given by domestic law where no treaty applies.
- Unified credit — The mechanism by which a US estate and gift tax exemption is applied.
- Updated return — India's route to voluntarily correct or file late within a statutory window, on payment of additional tax and with limits on what it may do.
- US estate tax — A tax on the value of US-situs assets at death, reaching non-residents who never lived in the United States, with a much smaller exemption than a US person receives.

Files that look like this one
Foreign tax paid in a country with no treaty
A client had worked a contract in a country with which their home country has no tax agreement, and had assumed the tax deducted there was simply lost. We established that domestic law offered relief in its own right, then went after the evidence: the foreign assessment, proof that the amount had been settled, and a schedule reconciling the foreign tax year to the home one. The claim was made on an amended return for each affected year. The engagement produced a documented relief position, with the supporting file kept in a form that answers a later query without a fresh investigation.
An estate filed without the credit a treaty allowed
An executor had already filed for a relative who died holding property in the United States while domiciled elsewhere. The filing applied the small credit available to a non-domiciled estate and stopped there. We reviewed the treaty position, valued the whole estate rather than only the American assets, and worked the credit out by reference to the proportion the US property represented. A corrective filing went in with the valuation file behind it. The engagement produced a revised return and a written explanation of the basis it rests on, which is what the executor needed before distributing to the beneficiaries.
An omitted rental income put right through an updated return
A client living abroad had left Indian rental income out of a return filed years earlier, and came to us after a bank asked for tax records. We checked first that the statutory window for an updated return was still open for that year, then rebuilt the rent received and the expenses that were actually allowable. The additional tax was computed and paid before filing. The engagement produced the filed return, the computation standing behind it, and a note of the years that could not be reopened by this route, so the client knew exactly where exposure remained.
Relief claimed twice on the same foreign income
A file arrived from a previous adviser in which the same foreign tax had been relieved once under a treaty article and again under the domestic unilateral rule, on the same income in the same year. We unwound the double claim, established which route was the correct one on the facts, and refiled. Alongside that we set out in writing which relief applies to which category of the client's income, so that the following year does not repeat it. The engagement produced corrected returns filed before any query was raised and a standing instruction the client's bookkeeper can follow.
Lifetime gifts that had quietly used up the credit
A family assumed the exemption would be available in full at death and had planned on that basis. Working through the papers we found transfers made over many years that had already consumed part of the unified credit, none of which had been reported at the time. The work consisted of reconstructing the gift history from bank records and property transfers, deciding which transfers were reportable, and bringing the missing gift filings up to date. The engagement produced a complete gift record, an estate projection built on what actually remained of the credit, and a corrected view of the family's plan.
Two non-treaty countries taxing one consulting income
A consultant billed clients in two countries, neither of which has a treaty with the country they live in, and both of which had deducted tax at source. The question was not whether relief existed but in what order to claim it, since each country caps relief by reference to its own tax on that income. We mapped the income by source, tested each claim separately, and filed. The engagement produced a computation memorandum showing the order the reliefs were taken in and the cap that bound in each case, which the consultant now reuses each year.
A Canadian Working in the US on a Work Visa
Immigration status and tax residence are different tests, and a visa says nothing about which country taxes the salary. The file fixes residence, applies the employment article, and sequences the two returns so the credit lands where it is usable.

Where the income was on the return and only the account report was missed, a narrow route allows late filing with a reason attached. It is open only while no income is unreported and no examination has begun, which is why it is checked first.

Foreign property income and sales are taxed in both countries by default; Section 216, FIRPTA and treaty credits are the standing toolkit.
Property is taxed where it sits, which is the one rule no treaty overrides. What the treaty does decide is the credit, the rate on the rent and what happens on the sale — and the clearance certificate on a disposition is applied for before closing, not after the buyer has already held the money back.
