Answer

The payer's annual return of tax withheld on US-source payments to foreign persons. 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.

What a late filing costs

The exception worth knowing

The withholding agent is liable for tax it failed to withhold, not merely for a penalty. Reconciling the recipient statements to this return, and to what was actually deposited, is where under-withholding is discovered.

What is the late filing penalty for Form 1042?
ItemAmount
Gross amount receivedC$34,000
Withheld at source (assumed 20% of gross)C$6,800
Deductible costsC$18,700
Net amount actually earnedC$15,300
Tax on the net amount (assumed graduated result)C$4,284
Difference recoverable by filingC$2,516

Filing on a net basis recovers C$2,516 of the C$6,800 withheld. That difference is the entire reason the elective return exists, and it is lost by not filing.

Where penalty for not declaring foreign bank account comes into this file

Most readers of this page are looking for penalty for not declaring foreign bank account. What follows sets out how it works for Form 1042: who is caught by it, what has to be filed, and what the work costs, agreed before it begins.

What these engagements turn on

Case study 1

Unfiled withholding years reconciled and filed in a single sequence

A company found that no annual return had ever been filed for payments it had been making to foreign suppliers, although some withholding had been deposited. We reconstructed each year from the payment ledger, matched it to what had been deposited, obtained the certificates that supported the rates applied, and identified the payments where nothing supported them. The returns were prepared in order and filed together with a covering explanation. The engagement produced a filed return for every year, a documented rate position per payment stream, and an agreed figure for the amounts still to be deposited.

Case study 2

Late return prepared after an acquirer's due diligence found the gap

A buyer's review of a target's tax affairs turned up foreign payments with no annual return behind them, and the transaction timetable was not going to wait. We established the size of the exposure from the payment records, distinguished the payments that were properly documented from those that were not, and set out the range the unwithheld tax could fall in. The return was then prepared on that analysis. The engagement produced a filed return, a quantified exposure both sides could negotiate against, and a schedule of the documentation to be obtained afterwards.

Case study 3

Statements reissued to agree with a corrected late return

Recipient statements had gone out for a year whose return was never filed, and the figures in them did not survive the reconciliation. We rebuilt the year from the deposits and the payment records, established what each recipient had actually been paid and withheld from, filed the return on those figures, and reissued the statements to match. Each recipient received a short explanation they could pass to their own adviser. The engagement produced a filed return, corrected statements agreeing with it, and a reconciliation running from the deposits to both.

Case study 4

Gross-up clauses reviewed alongside a late withholding return

A company facing unwithheld tax on several years of supplier payments wanted to know who ultimately bore it. We read the agreements behind each payment stream, separated the contracts that shifted the cost to the supplier from those that left it with the payer, and prepared the return and the deposit on the tax position regardless. Commercial recovery was then pursued only where the wording supported it. The engagement produced a filed return, a settled liability, and a contract-by-contract note of where the cost sat and what to change at the next renewal.

Case study 5

Late filing handled for a fund whose administrator had changed twice

Records for the unfiled year sat with former administrators, and no set of them was complete. We obtained what each held, reconciled them against the bank records, and identified the payments that appeared in one set and not another. Where a recipient's status could not be evidenced at all, we treated the payment as undocumented rather than assume the relief. The engagement produced a filed return built from reconciled records, a list of recipients whose documentation had to be obtained, and a single record retained by the fund itself rather than by its agents.

Case study 6

Final year's return filed after payments to foreign suppliers stopped

A company had stopped paying foreign suppliers part way through a year and assumed the return stopped with the payments. It did not, and that year sat unfiled while the earlier ones were in order. We established what had been paid in the short period, confirmed the rate applied and the documentation held, and filed the return for the year. The engagement produced a filed return closing the gap in an otherwise clean sequence, and a written note of when the obligation actually ends, so a final year is not missed again.

Case study 7

Information 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.

A Clean History Used to Remove a First Penalty

An administrative waiver can remove a first failure where the filing and payment record supports it, and it is spent once used. Whether to claim it now or keep it for a heavier year is a judgement made with the whole file in view.

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.

Performance income is taxed where earned — Regulation 105 in Canada, withholding agreements in the U.S. — with special treaty articles overriding the usual rules.

Performance income is taxed where the performance happens, and the deduction is usually taken at source on the gross fee before expenses. Recovering the difference is a filing exercise in the other country, and it only works if the tour, the residency and the withholding certificates were documented while the work was being done.

What people ask us about Form 1042

We missed the deadline for our annual withholding return — what now?

File it, and file it on figures you have reconciled rather than an estimate, because the return is the document any later review starts from. Two exposures run in parallel: the late return itself, and any tax that should have been withheld and was not. The second is usually the larger, because unwithheld tax is the withholding agent's own liability and the money has already left the company. So work out what should have been withheld, deposit what is owed, and file a return that agrees with both the recipient statements and the deposits.

Is the penalty on a late 1042 based on tax withheld or tax owed?

We will not put a figure to that here, because the amounts turn on the year and on how the failure is characterised, and a wrong number is worse than none. What is worth knowing is the shape of the exposure. It is charged by reference to the return and the delay rather than to your profit, so a year with little or no tax can still be expensive. And a year in which tax should have been withheld and was not carries that unwithheld tax as a separate liability of the payer. Ask for the figures for your own year, in writing.

Can we file several late years at once or one at a time?

Each year is its own return and each has to be internally consistent with the statements and deposits for that year, so they are prepared separately even when they go in together. Working through them in order matters, because a rate or a documentation position adopted for the earliest year usually carries through, and a certificate obtained now often evidences status for earlier payments as well. Filing them together does mean the whole position arrives at once, which is generally better than a trickle that prompts a query on each.

Will filing a late 1042 draw attention to the years before it?

It can, and that is a reason to know what those years look like before you file rather than after. A return plainly inconsistent with the pattern either side of it invites the question. The practical approach is to establish the position for every year still open, decide which of them need a return or a correction, and then file in a considered order. Arriving with a complete and reconciled position is a different conversation from arriving with a single year and no answer about the rest.

Our recipient statements went out but the return never did — does that help?

It helps in the sense that the underlying reporting exists and the recipients have what they need. It does not discharge the payer's own return, and it can make a gap more visible: the statements say what was withheld from each person, the deposits say what reached the administration, and the return is where the two are compared. If those three do not agree, the reconciliation is the work. Start from the statements already issued, because reissuing them later to match a corrected return is the harder version of the same job.

We under-withheld in a late year — can we recover it from the recipient?

That is a commercial question rather than a tax one, and it usually depends on what the contract says about gross-up. Liability for tax not withheld sits with the withholding agent whatever the answer, so the payer cannot wait for the recipient before settling it. Two things are worth doing at once: settle what is owed so it stops accruing, and read the contracts for the payments concerned, because a gross-up clause decides whether the cost ultimately sits with you or with the supplier. Fix the wording for future payments while you are there.

How do I get a refund of TCS collected on a foreign remittance?

You claim it on your Indian return for that year. The collected amount is credited against your total tax, and if it exceeds the tax due the balance is refunded like any excess payment. Two practical conditions: the collector must have filed its statement so the credit appears in your annual tax statement, and your PAN must be correctly recorded on the remittance. A salaried remitter can also ask their employer to account for it against salary withholding. See LRS limits and TCS.

Branch or subsidiary — which should we use to expand?

A branch keeps one taxpayer: results consolidate at home, losses are usable sooner, and the exposure is that the branch is a permanent establishment whose profit the host country taxes, sometimes with a branch tax on repatriation. A subsidiary is a separate taxpayer with limited liability and local rates, at the cost of withholding on dividends home and transfer pricing on everything between them. The deciding facts are usually expected losses, liability and exit plans. See branch against subsidiary.
