Lifetime Capital Gains Exemption Before Leaving Canada

Often, yes. The departure deemed sale happens just before you stop being resident, and you are treated as resident all year if you were resident throughout the year before. If your shares pass the qualified small business corporation tests that day, claim the exemption on Form T657. A sale in a later year, while you live abroad, generally cannot use it.

Who this is for

  • Canadian residents who own shares of a Canadian private corporation and are moving abroad
  • Owners deciding whether to crystallize the exemption before departure

Not covered here

  • Valuing private shares and the departure gain itself
  • Purifying a company or choosing a share or asset sale
  • Posting security to defer departure tax

Can I use the capital gains exemption on departure tax?

It can. When you leave Canada, you are deemed to sell most of your property at fair market value immediately before you stop being resident (s. 128.1(4)(b)). The lifetime capital gains exemption (LCGE) can shelter that deemed gain on your shares if you still have exemption room and two conditions hold:

  1. You count as resident in Canada throughout the departure year (see the next section).
  2. Your shares are qualified small business corporation shares at the moment of the deemed sale (s. 110.6(2.1)).

The exemption covers up to $1.275 million of gain over your lifetime, less any amount you used before. Any gain above what is left is taxed as an ordinary capital gain in the departure year. At the 50% inclusion rate, the deduction on line 25400 is half of the sheltered gain.

What makes a case not simple:

  • Anything that fixes a failing test (moving surplus cash out, crystallizing at an earlier date) has to be done before your departure date. After you leave, a later sale cannot use the exemption.
  • The company holds surplus cash or investments, so it may fail the asset tests on departure day.
  • You arrived in Canada recently, so you may not meet the residence rule, and shares you owned on arrival may not be deemed sold at all.
  • A large exemption claim can trigger minimum tax that is hard to recover once you are gone.

Gather: the share register and your cost, the company's balance sheet as of the departure date and for the past 24 months, a valuation, your arrival and departure dates with proof (prior-year return filed as a resident, lease or sale of your home, move date), and every past T657 you filed.

Am I resident "throughout the year" in the year I leave?

You are treated as resident all year if you were resident at any time in the departure year and resident throughout the year before (or throughout the year after, if you come back) (s. 110.6(5)). The CRA's line 25400 page states the same rule.

Your situationDeparture-year exemption?
Resident all of last year, leave this yearRule met
Arrived this year or last year, leave this yearRule not met: there is no full resident year before departure

Your departure date decides which year is the departure year. See the date you become a non-resident and Canadian tax residency.

Do my shares qualify on the departure date?

The shares must pass every test at the time of the deemed sale, which is just before you stop being resident (s. 110.6(1), "qualified small business corporation share"):

TestWhat it requires
At the deemed saleThe company is a small business corporation: a Canadian-controlled private corporation with all or substantially all of its asset value (the CRA reads this as 90%) in an active business carried on primarily in Canada, or in qualifying connected companies (CRA T4037)
Holding periodThroughout the 24 months before, no one other than you or a related person or partnership owned the shares
Assets during holdingThroughout those 24 months, the company was a Canadian-controlled private corporation and more than 50% of the asset value was in active business assets or qualifying connected companies

Idle cash, a portfolio, or a rental property inside the company counts against the tests. Removing such assets before departure is called purification; it is covered in selling your business. Newly issued shares and recent reorganizations can fail the holding test, so check them early.

Why can't I use the exemption after I become a non-resident?

The deduction is only for an individual resident in Canada throughout the year of the sale (s. 110.6(2.1)). If you sell the shares in a later year while living abroad, you were not resident at any time in that year, so the deemed-residence rule cannot help.

That is why the departure deemed sale matters: it may be your last chance to use the exemption on gains up to that day. After departure, your cost for Canadian tax is reset to the departure value (s. 128.1(4)(c)). If you move to the US, the US treatment of that cost is a separate question: see moving from Canada to the US.

If you were resident in Canada for 60 months or less in the 10 years before you leave, property you owned when you last arrived, or inherited after, is not deemed sold (s. 128.1(4)(b)(iv)). Those shares have no departure gain to shelter. Shares of a company you started after arriving are still deemed sold. See departure tax on private company shares.

What is crystallizing, and do I need to do it before I leave?

Crystallizing means deliberately triggering a gain while the shares qualify, for example by selling the shares to your own holding company at a price set by a joint election with that company on Form T2057 (s. 85(1)), so the exemption is used and your cost goes up. The election is due by the earlier of the two parties' filing deadlines for the year of the sale; a late one within three years costs a penalty (s. 85(6)-(7)). The departure deemed sale already works like a crystallization if the shares qualify that day and you meet the residence rule. A separate step before departure may be worth considering when:

  • The company may fail the asset tests on departure day, but passed them at an earlier date in a year when you met the residence rule.
  • You want to spread the gain over two tax years to manage minimum tax.

Crystallizing has its own anti-avoidance rules. Selling to a corporation you control is caught by s. 84.1: cash, a note or paid-up capital above your shares' paid-up capital and original cost is a deemed dividend the exemption cannot shelter, and the cost the exemption creates does not count for that rule later. A gain that is part of certain dividend or undervalue-transfer series loses the deduction (s. 110.6(7)). Plan it with a professional before you sign anything. Founders of investor-backed companies, see the exemption on a startup exit.

Will a large exemption claim trigger alternative minimum tax?

It may. For minimum tax, 30% of a gain sheltered by the exemption is still counted (s. 127.52). If your adjusted income for minimum tax exceeds the $181,440 exemption, the excess is taxed at 20.5% federally before credits, and you pay the higher of regular tax and minimum tax.

Minimum tax paid can be carried forward 7 years, but only recovered against regular tax that exceeds minimum tax in those years. As a non-resident with little Canadian income, you may have little or no tax to recover it against. Run the minimum tax calculation before choosing the timing.

What can reduce my exemption?

The amount you can claim is limited by what you have already used and by two other running totals in s. 110.6:

ItemEffect
Past exemption claimsReduce the lifetime amount left
Allowable business investment losses claimedReduce the gains you can shelter
Cumulative net investment loss (investment expenses, such as interest, above investment income since 1988)Reduces the deduction dollar for dollar; calculate it on Form T936
Unreported gainNo deduction on that gain if you knowingly or with gross negligence fail to report the gain or file within 1 year after the due date (s. 110.6(6))

I live in Quebec: is the exemption different?

Quebec has its own capital gains deduction on form TP-726.7-V, with a limit of $637,500 of taxable capital gains, which matches the federal limit once the inclusion rate is applied (Revenu Québec). Quebec allows it if you ceased to reside in Canada in the year and were resident in Canada throughout the year before.

Enclose TP-726.7-V with the Quebec return, plus copies of your T657 and federal return. The deadline is the later of 30 days after the federal claim and the return-filing deadline for that year. Missing documents cost $25 a day, up to $2,500. Quebec computes its own cumulative net investment loss on TP-726.6-V.

Which forms do I file?

FormPurpose
T1243Reports the deemed sale of your shares; the gain goes to Schedule 3
T657Calculates the capital gains deduction claimed on line 25400
T936Calculates your cumulative net investment loss, if you have investment income or expenses
TP-726.7-VQuebec deduction, for Quebec residents

All go with your departure-year return. The full departure filing list, including T1161 and the deferral election, is in leaving Canada.

Example

Figures are in Canadian dollars and illustrative only.

Shares qualify on departure day

Maya owns all the shares of a software company. Her cost is C$100. She was resident all of last year and leaves in August. On her departure date the shares are worth C$900,000, and the company passes all three tests.

  • Deemed gain on T1243: C$899,900.
  • Taxable capital gain: C$449,950.
  • Capital gains deduction on T657, if she never claimed before and has no cumulative net investment loss: C$449,950.
  • Minimum tax check: 30% of C$899,900 is C$269,970. Less the C$181,440 minimum tax exemption, C$88,530 remains; at 20.5% that is about C$18,150 of federal minimum tax before credits. With no other income her regular federal tax is nil, so most of it would be payable. Provincial tax is separate.

Too much cash on departure day

Same company, but it holds C$2 million of idle cash next to a business worth C$1 million. Active assets are about a third of the value, so the shares fail the departure-day test. Removing the cash before departure fixes that test only: if the cash was half the value or more at any point in the past 24 months, the shares still fail the holding-period test. An earlier crystallization helps only if the shares passed both tests at that earlier date.

Arrived 19 months before leaving

Jun arrived in Canada in March of Year 1 and leaves in October of Year 2.

  • Year 1 (if Jun crystallized that year): not resident throughout Year 1 or Year 2, so the rule fails.
  • Year 2: not resident throughout Year 1, so the deemed-residence rule fails, unless Jun comes back and is resident throughout Year 3.

If Jun does not return, the exemption is not available in either year. Shares Jun owned on arrival are not deemed sold at all under the 60-month rule above; shares of a company Jun started in Canada are, with no exemption.
