Answer

Withholding agents issuing statements to foreign recipients, and non-residents who need the statement to claim a refund or a foreign credit. The obligation is decided by facts rather than by tax owing, which is why a nil position does not remove it.

The rule on who files

Withholding agents issuing statements to foreign recipients, and non-residents who need the statement to claim a refund or a foreign credit.

When the rule breaks

The income and exemption codes on this slip decide how the payment is characterised on both sides of the border. A wrong code turns a treaty-rate dividend into fully withheld income, and the fix is a corrected slip, not a return position.

Who files Form 1042-S?
ItemAmount
Gross amount receivedC$59,000
Withheld at source (assumed 19% of gross)C$11,210
Deductible costsC$47,200
Net amount actually earnedC$11,800
Tax on the net amount (assumed graduated result)C$3,776
Difference recoverable by filingC$7,434

Filing on a net basis recovers C$7,434 of the C$11,210 withheld. That difference is the entire reason the elective return exists, and it is lost by not filing.

Illustrative figures, not a client engagement: the amounts are chosen to make the mechanism legible, and the rates and thresholds are assumptions stated for the example only. We confirm every one of them against the issuing authority for your own tax year before anything is filed.

What these engagements turn on

Case study 1

Establishing who the withholding agent was in a payment chain

A Canadian consultancy was paid for US-source work through an intermediary that collected from the end client and passed on the balance. Neither party had issued recipient statements, each assuming the other had assumed the role. We traced the payment flow, identified which party had control of the funds at the point they were paid to the foreign recipient, and documented the basis for that conclusion. The engagement produced a written allocation of the withholding agent role between the parties, and a set of recipient statements issued by the party that in fact held it.

Case study 2

A recipient who needed the statement to support a foreign credit

A non-resident had US-source income taxed at source but no slip to hand, and the foreign credit claimed at home was queried for want of evidence. We reconstructed the payments from banking records and contracts, established the character and source of each, and approached the payer for the statement it had not issued. The work produced the statement in the recipient's hands, a schedule reconciling it to the amounts actually received, and a written explanation filed in support of the credit claim.

Case study 3

First reporting season for a payer with foreign recipients

A US business had begun engaging suppliers outside the United States and had no process for recipient statements. We worked through each supplier relationship, separating payments that were US-source income to a foreign recipient from those belonging to other reporting, and settled the income characterisation for each category. The engagement produced a recipient register, the status documentation the payer needed to hold on file, and the first set of per-recipient statements issued and filed, with a note of the judgements made so the following year could be prepared consistently.

Case study 4

A wrong exemption code that recharacterised a treaty dividend

A foreign shareholder's dividend had been reported under a code that did not reflect the treaty position, so the slip described fully withheld income where a reduced rate had been intended. Taking the point on the return would have left the filing and the statement contradicting each other. We set out the treaty analysis for the payer, obtained a corrected statement from the withholding agent, and only then filed. The engagement produced the corrected slip, the correspondence that supports it, and a filed position matching the document the IRS holds.

Case study 5

Sorting which payments needed statements and which did not

A partnership making a mixed run of payments abroad — services, licence fees and distributions — had treated all of them alike. We examined each stream, established where the services were performed and what the payment was for, and separated those that were US-source income to a foreign recipient from those falling outside. The work produced a characterisation table tied to the underlying agreements, recipient statements for the payments that required them, and a documented reason for every payment left off.

Case study 6

Recipient statements for a person who changed residence mid-year

A payee had moved during the year, so part of the income was paid while they were a foreign person and part was not, and the payer had issued nothing rather than choose. We fixed the date the status changed, allocated each payment to the period it fell in, and confirmed which portion belonged on a recipient statement at all. The engagement produced a split schedule of payments, the status documentation supporting the change, and statements covering only the period in which the recipient was a foreign person.

Case study 7

One Employee in a State Nobody Had Registered In

A single person working from home can create payroll registration, withholding and sometimes an income tax filing for the company in that state. The review measures activity against each state's own threshold.

Case study 8

Selling Into the US Without an Entity, and Filing in Several States

State obligations are set by each state, and a treaty does not reach them. The review measures activity against each state's own thresholds and separates the states where registration is required from the ones where it is not.

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.

Software revenue crosses borders by default — sourcing rules, withholding on licence-like payments and IP location decide the effective rate.

Software revenue is rarely taxed where the team sits. Licence, subscription and service income are characterised differently by each side, and the answer decides withholding at source, treaty relief and whether a foreign customer creates a taxable presence at all — questions that are cheap to settle before the contract and expensive afterwards.

Asked next about Form 1042-S

Do I have to issue Form 1042-S to a Canadian contractor?

It depends on whether the payment is US-source income paid to a foreign recipient. This is a per-recipient statement of US-source income paid and tax withheld, so the question is not the contractor's nationality but the character and source of what you paid. Work carried out entirely outside the United States usually sits in a different reporting regime altogether. Settle source and characterisation first, because that decision fixes both whether a statement is due and which income code belongs on it.

Who counts as the withholding agent on a cross-border payment?

The withholding agent is the party that has control of the payment and pays it to the foreign recipient, and that is the party which issues the statement to the recipient and files it with the IRS. It is not always the ultimate payer. Where a payment passes through an intermediary, a paying agent or a custodian, each party in the chain has to know whether it is acting as the agent or relying on another party that has already assumed the role. Establish that in writing before the first payment, not at slip season.

I received a Form 1042-S — do I have to file anything?

Receiving the statement is not itself a filing obligation, but it is often the document that makes a filing worth making. The slip records what was paid to you and what was withheld at source. Where the tax withheld exceeds the tax actually due on that income, the statement is the evidence you need to claim the difference back. Where you are claiming relief for the same income at home, it is the evidence your own revenue authority will want for a foreign credit. So the recipient files when the slip shows more withheld than the position supports.

Does a nil or exempt payment still need a recipient statement?

Generally yes, and this is where payers are caught out. The obligation sits with the payment and the recipient's status rather than with the tax collected, so a payment reduced to nothing by a treaty rate is still a payment of US-source income to a foreign recipient. The exemption is reported rather than omitted: it is carried by the exemption code on the slip. A payer who simply leaves those payments out of its reporting has an unfiled statement, not a tidy file, even though nothing was held back.

My 1042-S shows the wrong income code — who corrects it?

The withholding agent does. The income and exemption codes decide how the payment is characterised on both sides of the border, and a wrong code can turn a treaty-rate dividend into fully withheld income. The fix is a corrected statement from the party that issued it, not a position taken on your own return. Filing against a slip you believe to be wrong leaves the two documents disagreeing, and the revenue authority reads the slip. Ask the payer for the correction, keep the correspondence, and file once the corrected statement is in hand where the timetable allows.

Do I issue one statement per recipient or one covering everything?

One per recipient, and that is the point of the form. Each foreign person who received US-source income gets their own statement, showing what was paid to them and what was withheld from them, with the codes that characterise that particular payment. A payer with several foreign recipients therefore has a set of statements to issue and file, not a single summary. Practically that means the recipient records — name, address, status and taxpayer identification — have to be in order well before the statements are prepared, because they are what the slips are built from.

Can an NRI claim back TDS deducted on Indian income?

Yes, by filing an Indian return for the year. Withholding on rent, interest, dividends, professional fees or a property sale is an advance payment, not a final tax, so where the actual liability is lower — because of the treaty, because of the basic exemption, or because the deduction was computed on gross proceeds rather than gain — the excess comes back as a refund. It needs your PAN, a validated Indian bank account and the deductor's statement filed. See Indian filing and credit claims.

How do I reduce withholding tax on a cross-border payment?

Before the payment, not after. Where a treaty gives a lower rate, the payer needs your residency declaration in hand to apply it; where the statutory rate would over-withhold on a gross amount, an advance application can authorise a reduced deduction on a net or estimated basis. Once the money has moved at the full rate, your remaining route is an elective return or a refund claim, which recovers the same cash far more slowly. See withholding refund and recovery.
