Section 116 holdback calculator

A buyer of Canadian property from a non-resident holds back a quarter of the gross price unless a clearance certificate is in hand. This shows the holdback, the tax actually due on the gain, and the cash a certificate releases at closing.

The disposition

C$

The whole price. The holdback is a percentage of this, not of the profit.

C$

What you paid, plus capital additions, adjusted as the rules require.

C$

Commission, legal fees and anything else wholly incurred on the sale.

%

Twenty-five per cent for ordinary taxable Canadian property. Certain property attracts a higher rate — check which class yours is in.

%

The inclusion rate for capital gains in the year of disposition. Confirm the figure for your year.

%

The non-resident rate on the taxable capital gain, including any provincial or federal surtax that applies.

%

The certificate is normally issued on payment of this percentage of the estimated gain, rather than of the price.

The obligation sits on the buyer, and that is why it is enforced

When a non-resident disposes of taxable Canadian property, the purchaser is liable for the tax unless a clearance certificate has been issued. That liability is what makes the holdback happen: a buyer who releases the full price and turns out to be wrong pays the tax themselves, with interest. So the holdback is not negotiable in practice, and a buyer's lawyer will insist on it whatever the seller's own view of the gain.

The percentage is applied to the gross proceeds, not the gain, so on a property that has appreciated modestly the holdback can be several times the real tax. The multiple is printed in the readout because it is the figure that tells you how badly the mismatch bites on your particular sale.

The certificate, and the notification clock

The remedy is to notify the tax authority of the disposition and pay, or provide acceptable security for, the tax on the estimated gain. A certificate is then issued and the buyer releases the funds. Because the certificate is priced on the gain rather than the price, the amount paid up front is far smaller than the holdback — and that difference is the number this calculator leads with.

There is a notification deadline, and it runs from the disposition rather than from the closing of your financing. Missing it attracts a penalty of its own on top of the holdback problem, so the notification belongs in the sale timetable and not in the post-completion tidy-up. The final position is still settled on a Canadian return for the year.

Worked example

A non-resident sells a Toronto property for 900,000 dollars. Adjusted cost base is 520,000 and costs of disposition are 40,000, so the gain is 340,000.

  1. Twenty-five per cent of the gross 900,000 is 225,000 held back at closing.
  2. Half the gain enters income, and tax on that at 26% is about 44,200 — roughly a fifth of the holdback.
  3. A certificate priced at a quarter of the gain costs 85,000 up front and releases the rest, freeing 140,000 of cash at closing.

Raise the cost base to 850,000 and the gain nearly disappears — but the holdback does not move at all. That is the whole case for the certificate.

What this calculator assumes

  • The twenty-five per cent holdback rate and the certificate pricing convention are the current ones and are cited below. Both are editable, and certain classes of property attract a higher rate.
  • The capital gains inclusion rate is an input, because it has been the subject of change. Confirm the figure for the year of disposition.
  • Principal residence relief, treaty exemptions and rollovers are not modelled and can remove the gain entirely.
  • The final tax is settled on a Canadian return for the year. This models the closing position, not the return.

An estimate, not advice. This is an estimate built from what you typed, not advice on your file. Nothing here reads your documents, checks your treaty article or looks at the year you are actually in. Where the number matters, we agree a fixed fee in writing before any work starts.

Where these figures come from

Any figure prefilled in the panel above is stated with the year it belongs to and can be changed. Rates and thresholds move; a calculator that asks you for the current one stays right, and one that hides a guess does not.

Cross-border tax case studies

Case study 1

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 2

A US LLC Owned From Canada

The two countries classify the vehicle differently, so relief that ought to apply frequently does not and the same profit can be taxed in both hands. The engagement examines whether the structure can be changed and what the change itself costs.

Case study 3

A Residency Determination Review After Leaving the Country

Residence is decided on ties, not on a form, and the review asks for evidence of every one of them. The file assembles the ties that were severed and the ones that remained, and answers the questionnaire against the treaty rather than around it.

Case study 4

A Family Trust Abroad With Reporting on Both Sides

A trust settled in one country and a beneficiary living in another produces reporting for the trust, the settlor and the beneficiary, on different forms and different dates. The engagement maps who files what before anything is prepared.

Case study 5

An Adjustment in One Country and No Relief in the Other

A pricing adjustment taxes the same profit twice unless the other country makes a corresponding one. The mutual agreement route is what produces that relief, and it is opened on a timetable set by the treaty rather than by either revenue authority.

Case study 6

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.

A Trust Abroad With a Canadian Connection

Contributions or beneficiaries in Canada can bring a foreign trust inside the Canadian net entirely. The analysis is who contributed what and when, because the answer decides whether the trust files here at all.

A Relief That Turned on Days Nobody Had Recorded

Treaty exemption, residence and social security are each decided by a count that has to be evidenced rather than recalled. The engagement builds the record from tickets, rosters and payroll before applying any article.

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.

Frequently asked questions

The purchaser. The buyer is liable for the tax if no clearance certificate has been issued, which is why a buyer will hold back a quarter of the gross price regardless of what the seller says the gain is.
The price. That is the mismatch this calculator exists to show: on a property that has appreciated modestly the holdback can be several times the actual tax.
The certificate is issued on payment of, or security for, the tax on the estimated gain rather than a percentage of the price. Paying the smaller figure up front releases the rest of the holdback at closing.
A penalty applies for the late notification, separate from the holdback problem. The deadline runs from the disposition itself, so it belongs in the sale timetable rather than the post-closing paperwork.
