Definition

An equity award generally taxed at vest, which means an employee who moved between grant and vest owes tax in a country they have left.

Where the money is

What decides these terms is presence and paperwork rather than intention. The exemption exists; proving the conditions were met is the work.

What one system calls it and the other does not

Cross-border files go wrong quietly here: one country has a concept the other does not, so a position that is obviously right domestically has no counterpart abroad. The mismatch is the exposure, and it is found by mapping the term in both systems rather than in one.

Where you will actually see it

From term to filing

If this term has turned up in a letter, a slip or an adviser's email and you are not sure which side of it you are on, that is a short call to the helpline rather than a research project. We would rather scope it properly than quote it quickly.

Entries here describe how something works rather than what it costs, because the two move independently: the mechanism is stable and the figures attached to it are revised. Our fee for handling it is agreed in writing before any work starts.

Files that look like this one

Case study 1

Vesting in the same year as a move between countries

An employee vested awards in the year of a move, and the whole amount appeared on one country's payroll. The starting point was the plan's earning period for each tranche, which aligned neither with the calendar year nor with the move date. Work consisted of building the sourced split for each tranche, deciding which country received which portion, and preparing the two returns so that the credit claimed in one matched the income reported in the other. The engagement produced a filed position in both countries resting on a single schedule.

Case study 2

A vest slip arriving after the employee had emigrated

A slip arrived in the former country of employment for a vest that occurred well after the client had emigrated, and they had assumed no filing obligation remained there. Work began by establishing whether the award related to work performed before departure and, if so, in what proportion. A non-resident return was prepared for the year of vest, reporting the sourced portion rather than the amount on the slip, with the earning-period evidence assembled in advance. The engagement produced a filed return and a matching credit claim in the country of residence.

Case study 3

Reporting shares sold to fund withholding on a vest

Shares had been sold at vest to fund withholding, and the client reported the sale as an ordinary disposal unconnected to employment income, producing a result that made sense on neither return. Work consisted of identifying the vested value, the amount withheld, and the shares disposed of to fund it, then reporting the employment income in full and the disposal against a cost equal to the value already taxed. The engagement produced corrected reporting that stopped the same amount being taxed twice.

Case study 4

Reconciling plan statements with brokerage records before filing

The client held plan statements from an employer portal and transaction records from a broker, and the two disagreed about what had happened and when. Work consisted of matching each vest to its settlement, identifying units withheld at source, and separating amounts settled in shares from amounts settled in cash before any figure went on a return. The engagement produced a single reconciled schedule of awards and disposals, agreed against both sets of records, which became the basis for the returns in each country.

Case study 5

Sourcing several tranches with different earning periods

Several tranches vested in the same year, each granted at a different time, so each had its own earning period and its own split between the countries involved. The client had applied one ratio to the total. Work consisted of reading each grant's terms, setting the earning window for each tranche, and apportioning them one at a time against a single workday record. The engagement produced a tranche-by-tranche schedule showing the sourced portion of each, which changed the balance owing in both countries.

Case study 6

Recovering tax withheld in the wrong country on vest

Tax was withheld at vest by a payroll in a country where the client no longer worked and had not worked for most of the earning period. The starting question was how to recover it, which depended on filing rather than on asking the employer. Work consisted of establishing the portion properly sourced there, preparing a non-resident return claiming the excess withholding back, and adjusting the credit claimed in the country of residence to match. The engagement produced a recovered withholding and two returns that agree with each other.

Case study 7

Paying 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.

Case study 8

An Assignment Priced Without Counting the Days

Nearly every relief in a mobility file — treaty exemption, residence, social security — is decided by a day count that has to be evidenced. The engagement puts the tracking in place at the start, because it cannot be reconstructed at the end.

Core International & Cross-Border Tax Services

International Tax Planning & Advisory

Strategy and compliance for income, assets and families spread across borders.

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 Restricted share unit

Why are my RSUs taxed when I did not sell anything?

Because the taxing event is generally the vest, not the sale. When the restrictions lapse and the units settle into shares, you have received something of value, and the value at that moment is employment income even though the shares are still sitting in the account. The sale is a separate event later, measured against the value already taxed. This catches people out twice: once because tax is owed in a year with no cash, and again because the broker's statement shows a sale of shares to cover it, which looks like a second taxable transaction and is not.

I moved countries before my RSUs vested, who taxes them?

Both may. The award is generally taxed when it vests, but it was earned over the period running up to that date, and if that period spans a move, each country tends to claim the portion earned while you were working there. So the country you left can tax part of an amount that arrives after you have gone, and the country you have arrived in taxes the rest. The practical problem is that only one of them is likely to see any withholding, so one return shows a balance owing and the other an over-payment.

Do I still file where I used to work if I have left?

If part of the vested amount is sourced to that country, generally yes, and the filing is usually a non-resident one covering the year of vest rather than a full resident return. People assume the obligation ended with the move, and then a slip appears much later. Deal with it in the year it arises. Filing late in one country while a credit has already been claimed in the other means the credit claim has to be revisited too, and the years in which each is claimed then have to be reconciled by hand.

What value is my RSU income based on?

Generally the value of the shares on the day they vest and settle, not the value on the day they were granted and not the price you eventually sell at. The grant-date value is a plan figure and has no bearing on the employment income. Everything that happens to the share price after the vest date belongs in a different computation. Confusion here is common because plan statements and brokerage statements report different things, and it is worth setting the two side by side before either return is prepared.

Why did my broker sell some of my shares automatically?

Many plans settle a vest net of an amount withheld for tax, either by holding back units or by selling enough shares to fund it. That is a withholding mechanism rather than a decision you made, and the shares arriving in your account are already net of it. Two things follow. The amount treated as employment income is the full value that vested, not the net you received. And the shares sold to fund the withholding are a disposal in their own right, usually at close to the value just taxed, so they should produce very little further gain if reported correctly.

Does my employer's withholding cover what I actually owe?

Rarely, where a move is involved. Withholding is calculated by a payroll system in one country, on the assumption that the whole amount belongs there, and it does not know which months you spent working elsewhere. It may also be applied at a flat supplemental rate that bears no relation to your marginal position. Treat the withheld amount as a payment on account in one country only, and work out the real liability in each country from the sourced split. Waiting until both returns are prepared before spending the proceeds is sensible.

Is the sale of foreign property taxable where I live?

For a resident, yes — worldwide gains are taxable, and the gain is computed in your own currency, so the exchange rate at purchase and at sale changes the number even when the local-currency price did not move. The country where the property sits usually taxes it too, often with a withholding or clearance step before closing, and that tax becomes a credit. A principal residence relief may apply to a home abroad on the same terms as one at home. See principal residence and foreign property.

Do NRIs pay tax on money sent to India?

Sending your own funds to India is a transfer of capital, not income, so the remittance itself is not taxed. What is taxable is income the money then earns in India — interest, rent, capital gains — under the rules for the account type it sits in. Sending money out of India is the direction that needs certification before the bank will act. See NRE, NRO and FCNR accounts.
