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
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.
Read how this one runsAccounts Reported Late When the Income Already Was
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.
Read how this one runsInformation Returns Missed Behind a Correct Return
The heaviest exposure on a cross-border file is often a disclosure form rather than the tax. Where the return itself was right, the procedures for late information returns turn on a reasonable-cause narrative with dates and documents behind it.
Read how this one runsDeduction at Source on Deposit Interest, Recovered
Where the treaty rate is lower than what was deducted, the difference comes back through a return rather than at source. The file establishes entitlement and files for the years still open.
Read how this one runsPaying a Dividend Up to a Foreign Parent
The withholding rate depends on the treaty, on the size of the holding, and on whether the parent is the beneficial owner rather than a conduit. Establishing all three before the payment is what secures the lower rate at source.
Read how this one runsCatching Up From Inside the United States
The domestic route suits a filer who was resident in the US through the missed years, and it differs from the offshore one in what it asks for and what it costs. Choosing between them before anything is filed is the whole engagement.
Read how this one runsNever Filed a US Return — and Only Just Found Out
Born in the United States, left as an infant, and told by a bank that the returns were owed all along. The work is sequencing: establish which years are actually open, choose the catch-up route on the facts rather than filing quietly, and claim the exclusions and credits that were never taken.
Read how this one runsAn Indian Company Paying a Foreign Supplier
Payments abroad carry deduction at source and a certification filed before the money moves. Whether the treaty reduces the rate depends on what is being bought, and the classification is the decision the whole filing rests on.

Cross-Border Real Estate
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.
