Answer

The transfer certificate that releases US-situs assets held by a custodian after a non-resident's death. The exposure on this kind of filing is charged by reference to the form and the delay rather than to the tax, which is why an unfiled year with no tax can still be expensive.

The carve-out

This is the practical bottleneck in a cross-border estate. The custodian will not release the assets without it, the certificate follows the estate tax filing, and the whole sequence runs on the IRS's timetable rather than the family's.

The full treatment — who it binds, the deadline, the penalty and the fixed fee — is on 5173 — transfer certificate. One call now is worth more than a filing season of guessing.

Cross-border situations we are engaged for

Case study 1

Estate tax filing rebuilt from archived statements long after the death

The administration had stalled years earlier and the US holding had been left frozen throughout. We obtained the custodian's archived records, reconstructed the date-of-death position from them, prepared the estate tax filing on that evidence, and then requested the transfer certificate. The engagement produced a filed return supported by source documents, a valuation file the executor can produce if anyone questions it later, and the clearance that finally moved the account.

Case study 2

Family who believed a nil position meant nothing needed filing

Nothing had been filed because the numbers looked small and no tax appeared to be due, and the account had been frozen ever since. We explained the order the process actually runs in, documented the situs inventory and the values, recorded the position taken and filed it, then applied for the certificate on that record. The engagement produced a filed position where none had existed, the clearance, and a short written note of the reasoning for the beneficiaries.

Case study 3

Authority to act had lapsed before the clearance was obtained

Years of delay had left the appointment the family relied on out of date, and the custodian would not accept correspondence from the person signing it. We re-established who was entitled to act and evidenced it, then picked up the fiscal work: inventory, valuation, estate tax filing, certificate request. The engagement produced current documentary authority, a completed filing, a request the institution accepted, and a chronology showing what had been done in whose name.

Case study 4

Beneficiaries pressing an executor while correspondence went in circles

Letters had been going back and forth with the institution for a long time without advancing, and the beneficiaries had lost confidence in the process. We took over the correspondence as a single point of contact, set out the sequence in writing, and redirected the effort into the estate tax filing the certificate depends on. The engagement produced a completed filing, the clearance, and a written record the executor could show the family at each stage.

Case study 5

Valuation evidence assembled where the currency history mattered

The holding had been bought in one currency and the estate was being reported in another, and the delay meant the rates and corporate actions in between had to be evidenced rather than asserted. We built the valuation from the custodian's own history, documented the conversion basis used, and filed on that footing before requesting the certificate. The engagement produced a filed return with its workings attached, and a valuation the executor can still defend years from now.

Case study 6

Two estates in sequence over one frozen holding

The first estate's clearance was still outstanding when the beneficiary who was to inherit the holding died, so a second administration arrived on top of an unfinished one. We separated the two, completed the first estate's filing and obtained its certificate on the original facts, then dealt with the second on its own footing. The engagement produced filings in the correct order, the clearances that followed them, and a record showing which assets passed under which administration.

Case study 7

Ten Years of Missed Returns Filed as One Engagement

Filing many years at once is a sequencing problem: carry-forwards, instalments and credits from the earliest year feed the latest. Filing them out of order is what turns a recoverable position into an assessed one.

Case study 8

A Penalty Argued on the Facts Rather Than the Form

Reasonable cause is a documented story with dates, not an assertion of good intent. The engagement assembles what the client actually knew and when, and puts the sequence in writing alongside the filings it explains.

One coordinating team: filings on every side of the border are sequenced so treaty relief and foreign tax credits are claimed once — and in the right country.
U.S. & Cross-Border Tax Returns
Dual filers: U.S. citizens in Canada and Canadians with U.S. income run two parallel systems — we prepare both, in the right order, every year.
Expat & Emigration Tax
The move year is its own project: the elections and valuations filed that year decide the next decade of both countries’ returns.
Non-Resident Canadian Tax
Default withholding is 25% of gross: elective returns routinely turn over-withheld rent and pensions into refunds.
Transfer Pricing & BEPS
Documentation prepared with the return is the cheapest insurance in international tax; reconstructing it during an audit is the most expensive.
Cross-Border Estates & Trusts
Wills drafted for one country routinely misfire in the other — deemed disposition here, estate tax there, credits in between.
Cross-Border Corporate Tax
Expansion raises the same four questions every time — entity, PE, repatriation, payroll. We answer them before the tax authorities do.
India Tax for NRIs & Returning Residents
The deduction is taken on the sale price, not the gain — which is why an NRI property sale strands cash unless the certificate is applied for before closing.
Canadian Tax with a Foreign Element
Residency is decided on facts, not on a form — and the year you arrive or leave is the one where the largest amounts turn on the smallest details.
UAE Tax for Expats & Their Home Country
A zero-tax country is only half the answer — the question that decides the bill is whether the country you came from still treats you as resident.

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.

Questions that come up on Form 5173

Is there a late filing penalty for a transfer certificate request?

The request is not a return with a balance owing, so it does not behave like a late filing in the ordinary sense. The exposure sits behind it, on the estate tax filing the certificate follows, and that filing has its own deadline and its own consequences for missing it. Meanwhile the cost of delay is real but commercial rather than penal: the custodian keeps holding the assets, beneficiaries wait, and the estate carries whatever market and currency movement happens while it waits. Where an estate is already behind, the useful question is not what the request costs but how soon the filing behind it can be completed properly.

Our estate tax filing is late — will the IRS still issue a certificate?

A late filing does not remove the route to a certificate; it changes the order of work and the amount of evidence needed. The filing still has to be made, and made completely, because the clearance follows it. The practical difficulty in an old estate is that the record has cooled: institutions have merged, statements are archived, and the people who knew what the deceased owned may no longer be available. That is why a late case is usually reconstruction work first and computation second. Getting the reconstruction right is what stops the request bouncing back and adding another round of correspondence.

What does the delay cost the family while the assets sit frozen?

Nothing is distributed, and in most estates that is the whole of it. The holding stays in the custodian's hands, the beneficiaries' entitlements stay theoretical, and the estate keeps whatever market and exchange-rate exposure the position carries in the meantime. Executors also absorb a quieter cost — they remain personally engaged in an administration they expected to have closed. None of that is a penalty, but all of it is avoidable time. The way out of it is generally to stop corresponding with the institution about the freeze and start assembling the estate tax filing the certificate depends on.

Can a bank release US assets while the certificate is still pending?

In practice the institutions that ask for a transfer certificate do not move without it, and treating that as negotiable wastes the very time the family is trying to save. The custodian is not asserting a tax position of its own; it is waiting for IRS clearance and will hold until it has it. Where liquidity matters — funeral costs, professional fees, tax due elsewhere — the realistic answers lie outside the frozen account, and they are better planned for at the start of an administration than discovered halfway through. The account itself moves when the certificate arrives, and not before.

We found a US account years after the death — what now?

Start with the record rather than the correspondence. What the IRS and the custodian both need is an inventory of the US-situs assets and a defensible value at the date of death, and in an old case both have to be rebuilt from institutional archives. Once that exists, the estate tax filing can be prepared on it and the certificate requested. Coming to it late is not a bar. It does mean the evidential work is heavier, and it means an executor who has already distributed the rest of the estate should take advice before promising anyone a timetable.

Does waiting make the estate tax position harder to prove?

Usually, yes — not because the rules move but because the evidence decays. Date-of-death values have to come from somewhere, and the further away that date is, the more work it takes to get statements, corporate actions and currency rates into a form that supports a filing. Letters of appointment go stale, contacts at the institution change, and family memory of what was held stops being reliable. None of that changes the answer the filing should reach. It changes how long it takes to prove, which is the practical argument for dealing with a frozen US account early in an administration.

Do Canada and the United States share tax information?

Yes, through more than one channel. The treaty has an exchange-of-information article that supports both routine and on-request exchange. Separately, an intergovernmental agreement has Canadian financial institutions identify US-reportable accounts and report them to the CRA, which passes them to the IRS, with the reverse flow for Canadian residents. Most other country pairs use the Common Reporting Standard for the same purpose. See FATCA reporting.

How do you avoid double taxation?

You claim relief once, in the right country, in the right order. Usually the source country taxes first, the residence country then gives a credit for that tax against its own charge on the same income, and a treaty caps the source-country rate. Getting the order wrong is what produces a double charge you then have to unwind. The mechanism differs by income type, which is why we map the whole position before filing either return. See how to avoid double taxation.
