Definition

Recovery of tax paid on business inputs. Whether a non-resident can recover at all depends on which registration route it took.

What it changes

These terms describe obligations triggered by supplies and by stock rather than by profit, which is why a business can owe them in a year it made no money at all.

Where the definitions diverge

The dangerous version of this is not a disagreement but a gap: a category that exists in one system and simply has no counterpart in the other. Nothing contradicts anything, so nothing looks wrong, and the position is only tested when an authority asks where the income went.

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. Describe the situation in your own words; translating it into forms is our job.

Terms like this are worth learning only to the point where you can spot the question. Past that point it is a computation on your own facts, and that is a conversation rather than a glossary entry.

Cross-border situations we are engaged for

Case study 1

Recovery lost to the registration route rather than the invoices

A non-resident supplier presented a file of local invoices and asked why the tax on them had never been recovered. The invoices were in order. The registration was the problem: the business had entered under a route for non-resident digital suppliers which collects tax and grants no recovery. The engagement produced a written explanation for the board of why the tax was a cost under the route chosen, a comparison with a full registration, and a plan to move that puts recovery in place for costs incurred after the switch.

Case study 2

Rebuilding invoices so that a genuine claim could be supported

An audit questioned a period's claims because a substantial part of the supporting documents lacked the supplier's registration number and showed tax as a single combined figure. The underlying supplies were real and the entitlement was not in doubt. Each supplier was approached for a compliant document while the relationships were still live, and the few that could not be obtained were conceded rather than argued. The work produced a re-documented claim, a written response distinguishing the two groups, and a purchase-ledger control that rejects a non-compliant invoice on entry.

Case study 3

Sequencing a registration around local set-up costs

A business about to lease premises, fit them out and engage local advisers asked whether it should register before or after the spending. The categories of cost were listed and tested against the rules for recovery on inputs held or used when a registration takes effect, and the sequence mattered to a material part of the fit-out. The engagement produced a recommended effective date, an order of events for the lease and the supplier contracts, and a note to the client's project manager on which invoices to date after that point.

Case study 4

An apportionment basis that could be defended on audit

A business making both taxable and exempt supplies had been recovering tax on overheads on a basis nobody could explain, applied differently in different periods. The activities were separated, the overheads grouped by what they were actually used for, and one basis chosen that the client's own management reporting produces without extra work. The engagement produced a written apportionment method with the reasoning recorded, recalculated claims for the open periods on that method, and a note that the basis is to be reviewed when the mix of activities changes.

Case study 5

Border tax stranded in the name of a customs broker

Tax paid at import over several years had never been recovered, because the entries had been made in the broker's own name as a matter of routine. The flow of title was established from the sales contracts, the broker's standing instructions rewritten, and corrected entries put in place for shipments going forward. The engagement produced recovery on the periods still open to amendment, a written account of the earlier periods and why they were not claimed, and an import checklist the client's logistics team applies to each consignment.

Case study 6

Defending credits an assessment proposed to reverse

An assessment disallowed a block of credits on the basis that the costs related to an activity outside the business. The costs concerned a project the business had begun and later abandoned, which made the connection real but not obvious from the ledger. Board papers, the project plan and the correspondence with the counterparty were assembled into a chronology. The work produced a written response setting out the business purpose of each group of costs, and the credits were allowed on the strength of the contemporaneous record.

Case study 7

Green Card Kept, Moved to Canada — Both Returns Still Due

Holding a green card does not end the US filing obligation, and living in Canada starts a Canadian one. The engagement fixes residence under the treaty tie-breaker, then decides which return the relief is claimed on so the two do not contradict each other.

Case study 8

A Student or Researcher Covered by a Treaty Article

Several treaties carry a dedicated article for students, trainees and visiting researchers that displaces the ordinary employment rules. Whether it applies turns on the purpose of the stay and the source of the funds, both of which are evidenced rather than asserted.

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.

Remote Workers & Digital Nomads

Working from anywhere doesn't mean taxed nowhere: residency defaults, employer payroll exposure and treaty relief decide where income actually lands.

Working from another country does not by itself end tax residence in the one you left, and it can start one where you are sitting. Day counts, ties, the employer's own exposure and the treaty tie-breaker all point at the same question, and the year you move is the year it has to be answered on paper.

Questions that come up on Input tax credit

What is an input tax credit?

It is the mechanism that stops sales tax accumulating at each stage of a supply chain. A registered business charges tax on what it sells and bears tax on what it buys; the credit lets it set the tax on its purchases against the tax on its sales, so it remits the difference and carries none of it itself. The tax ends up borne by the final consumer, who has nothing to set it against. For a non-resident business the point to check first is whether it is entitled to the credit at all, because some registration routes for foreign suppliers carry no right of recovery.

Why can I not recover the sales tax I paid abroad?

Three reasons account for most cases. You may not be registered in that country, and recovery is generally a right of registrants rather than of businesses at large. You may be registered under a simplified route for non-resident suppliers, which collects tax without granting recovery. Or the cost may not qualify, because it was used for exempt supplies, or was personal, or falls in a category the rules exclude. Work through them in that order: the first two are questions about your registration and are fixable going forward, and only the third is a question about the invoice in front of you.

What records do I need to claim input tax credits?

Enough to show that the tax was charged by a registered supplier on a taxable supply made to you, for use in your business. In practice that means invoices carrying the supplier's registration number, a description of what was supplied, the date, and the tax shown as a separate amount. Payment records alone are not enough, and neither is a statement of account. The failure is mundane: the entitlement is genuine, the supply happened, and the claim is refused because the document does not carry the details the rules require. Fix the documents while the supplier still answers the phone.

Can I claim tax on costs incurred before I registered?

Sometimes, and it is worth asking rather than assuming. Systems commonly allow some recovery on inputs held or used at the time a registration takes effect, and treat services consumed beforehand less generously. The answer turns on when the cost was incurred, when the thing bought was used, and the date the registration takes effect, which is one reason that date is worth choosing rather than accepting. Where a business is about to incur significant local set-up costs, the order in which it registers and spends can decide whether the tax on them is recoverable at all.

How do I split credits between taxable and exempt activities?

By use, and the method has to be reasonable and applied consistently. Tax on inputs used wholly for taxable supplies is recoverable, tax on inputs used for exempt supplies is not, and mixed inputs are apportioned. The difficulty is never the principle, it is the overheads: premises, software, professional fees. Choose a basis you can support from your own records, write down why you chose it, and apply it the same way each period. An apportionment reconstructed at audit on a different basis from the one used in the returns is the problem more often than the proportion itself.

Can I recover the tax paid when my goods were imported?

Only if you incurred it in the character the rules require, which usually means as the importer of record and as a registrant. This is where non-resident businesses most often lose money: the customs entry is made in the name of a broker, a customer or a related company, so the tax paid at the border sits with an entity that has no claim to it, or with one that has a claim and never makes it. Check whose name is on the entries before you check your returns, because no amount of work on a return fixes an entry made in the wrong name.

Can I avoid capital gains tax on a foreign property?

Not by virtue of it being foreign — there is no exemption for that, and the "keep it offshore" advice you may have read is how people acquire penalties rather than savings. What genuinely reduces the gain is ordinary and legitimate: principal residence relief where the property qualifies and the designation is made correctly, a properly built cost base including acquisition costs and capital improvements, the timing of the disposition, the treaty rules for real property, and credit for the foreign tax paid. See principal residence and foreign property.

What happens if I have not filed for several years?

Missed years are handled as one package, not one at a time, because the route chosen for the first year determines the relief available for the rest. Each country has a disclosure or relief programme with its own conditions, and entering the right one — before the authority contacts you — is usually what keeps penalties down. Filing quietly outside a programme forfeits that protection. See catching up on missed returns.
