CGT and CGWT treatment of listed and unlisted securities — rates, the final tax regime, and the securities disposal lifecycle.
Lecture script, exemptions, rollovers, safe harbours, comparative tables, and the Mermaid disposal lifecycle flowchart.
Practical templates, instructor handouts, assessment materials, and classroom activities for CGT on capital markets.
Analytical lesson plan and teaching materials (comparative common‑law approach: UK, Australia, Canada)
This lesson trains learners to apply Capital Gains Tax (CGT) doctrine to securities transactions across the full capital‑markets lifecycle: from trade instruction and exchange execution through clearing/settlement, ownership recording (often through nominees and central securities depositories), and finally to tax reporting, valuation, exemptions/rollovers, and anti‑avoidance controls. This topic is uniquely “capital‑markets heavy” because a single share disposal can involve multiple dates (trade date vs settlement date), multiple ownership layers (beneficial vs legal title), and multiple legal regimes (tax statute + exchange/CSD rules + broker reporting regimes).
Because you did not specify a jurisdiction, the lesson is built as a comparative framework grounded in three common‑law comparators:
By the end of the lesson, learners should be able to (1) map a securities disposal from market execution to tax return; (2) determine the correct “tax date” and ownership identity; (3) handle unlisted share valuations and reorganizations; (4) apply exemptions/rollovers (SSE; scrip‑for‑scrip; s85.1; portfolio thresholds; excluded property) and (5) spot anti‑avoidance risk patterns (wash sales; step transactions; GAAR/GAAB).
At the end of Lesson 18, participants will be able to:
A 180‑minute class is ideal. The content is procedural and benefits from worked examples and document exercises.
Suggested sequence (instructor timemap):
- Conceptual foundations and market plumbing (35 min)
- Listed shares: timing, identification, reporting (45
min)
- Unlisted shares: valuation, reorganizations, related parties,
anti‑avoidance (60 min)
- Exemptions/rollovers: comparative table workshop (25
min)
- Case study + debrief (15 min)
Instructor opening (5–7 minutes):
“CGT law was designed for disposals of assets. Capital markets
industrialize disposals: the law must map a continuous stream of
anonymous trades and multi‑layer custody structures into a taxable
event. That mapping breaks into four questions: Who disposed?
What asset? When? What consideration and base cost?”
Anchor learners to two “plumbing facts” you will reuse:
- Many securities markets settle Delivery‑versus‑Payment (DvP); for
example, CREST is described as a DvP settlement system and CHESS is a
settlement system facilitating DvP for Australian market transactions.
- Settlement cycles are standardized by regulation in some
jurisdictions; the UK FCA explains that CSDR sets a standard settlement
cycle of T+2 (with T = trade date) and indicates
planned transition to T+1 in 2027.
Teach timing as a three‑layer model:
Layer one: market reality
- Investors “trade” first, then settle later through a
clearing/settlement system (CREST, CHESS, CDSX).
Layer two: tax statute timing rule
- UK: TCGA 1992 s28 fixes time of disposal/acquisition
under a contract as the time the contract is made (unless conditional).
For exchange‑traded shares this generally maps to trade date (the
contract is concluded), not settlement date.
- Australia: ITAA 1997 s104‑10(3) states time of CGT
event A1 is when you enter into the contract for disposal (or, if no
contract, when change of ownership occurs).
- Canada: CRA’s long‑standing published position is
often summarized (including via TEI roundtable responses) as using the
settlement date for shares sold on an exchange as the
date of disposition “as determined by the rules of a stock exchange.”
(Treat this as a jurisdiction‑specific “gotcha”; you should flag to
learners that primary CRA commentary is circulated through technical
interpretation records.)
Layer three: reporting year/return mechanics
- UK reporting channel: shares/CGT are frequently
reported via Self Assessment using the SA108 CGT pages, supported by
SA108 notes (including worksheets for “whole holdings of shares”).
- Canada reporting channel: publicly traded shares and
mutual fund units are reported on Schedule 3 (“Line 4” category
guidance).
Instructor technique: put the three jurisdictions
side‑by‑side on a whiteboard:
- UK: contract date drives tax date.
- Australia: contract date drives time of event.
- Canada: settlement date may drive date of disposition for
exchange‑traded shares per CRA position.
UK policy problem: “You bought identical shares on different dates for different prices. Which shares did you sell?” HMRC’s HS284 teaches that from 6 April 2008 shares of the same class are pooled into a Section 104 holding, with average cost, subject to “same day” and “bed and breakfasting” matching rules.
You should explicitly walk through:
- Section 104 pooling (TCGA s104): same class, same
company, same capacity → pooled asset.
- “Bed and breakfast” anti‑manipulation (TCGA s106A):
disposals matched with reacquisitions within a statutory window rather
than the pool (conceptually similar in effect to superficial loss logic
in Canada).
Mini‑example (talk track):
“Investor holds 10,000 shares in a pool. Sells 2,000 and buys 2,000 back
within 30 days. UK rules stop you from manufacturing a gain/loss
positioning by matching the disposal with the reacquisition.”
Canada (very explicit broker/dealer reporting):
- CRA’s T5008 guide states traders/dealers must file a T5008
information return to report purchases and sales of
securities, including sales made “as an agent or nominee,” and
issuers/agents use it for redemptions/acquisitions/cancellations.
Australia (third‑party reporting ecosystem):
- ATO describes its data collection powers including data‑matching
programs that target “share market transactions.”
- ATO’s approved forms lists include “Transfers of shares and units
report” forms (Listed Entities / Market Participants) with legislative
references to Schedule 1 of the Taxation Administration Act 1953 (as
shown in the ATO forms list).
UK (tax reporting is more taxpayer‑centric):
- HMRC emphasizes taxpayer record‑keeping and computing gains correctly,
including keeping records for CGT computations.
- Practical reporting channel for many taxpayers is via Self Assessment
SA108.
Exchange and settlement mechanisms (market plumbing you reference
in questions):
- Australia: ASX CHESS is described as a centralized
electronic subregister with holdings “recognized in law as if maintained
directly by the issuer,” facilitating DvP settlement.
- UK: Euroclear UK & International describes CREST
settlement with DvP features and accounts held by brokers/custodians and
others.
- Canada: Bank of Canada describes CDSX as clearing and
settling eligible exchange‑traded and OTC transactions; CDS provides
depository services and ledger positions.
Key teaching point: listed shares usually have observable market price; unlisted shares are evidence‑intensive and trigger market value substitution rules more often (connected persons; non‑arm’s‑length; unascertainable consideration; tax rollovers).
UK valuation anchors:
- TCGA s17 imposes a market value basis where
transactions are not bargains at arm’s length or consideration is
unvalued.
- HMRC’s manuals emphasize the statutory “open market” concept: an open
market sale between a hypothetical willing buyer and seller, and state
that Shares and Assets Valuation (SAV) handle valuations of unquoted
shares.
Canada valuation anchors:
- ITA s69 deems proceeds and cost to fair market value
for many non‑arm’s‑length dispositions, gifts, and transactions not
changing beneficial ownership.
- CRA’s IC 89‑3 provides a policy framework for business equity
valuations, discussing valuation approaches (liquidation vs going
concern) and the need for objective, reasoned judgment.
Australia valuation anchors:
- ITAA 1997 s116‑30 replaces capital proceeds with market value when
proceeds cannot be valued or are not arm’s length (market value
substitution).
- ATO guidance emphasizes valuations must be “objective and
supportable.”
Instructor drill: Have learners identify “valuation triggers” in a fact pattern: related‑party sale, gift, earn‑out, share‑for‑share, pre‑IPO reclass.
These transactions are central to mergers, takeovers, and pre‑IPO restructures.
UK (TCGA share exchange/reorganization framing):
- TCGA s135 is a core statutory mechanism supporting “no disposal”
treatment for certain share exchanges/reorganizations (and interacts
with other rules on takeovers).
- HMRC’s manual discusses scope limitations: e.g., s135 concerns an
“exchange” where shares are issued (it won’t apply to a straight swap of
already‑issued shares).
- HMRC also describes an advance clearance procedure
for share exchange anti‑avoidance uncertainty (not mandatory).
Australia (scrip‑for‑scrip rollover):
- ITAA 1997 Subdivision 124‑M provides scrip‑for‑scrip rollover;
s124‑780 illustrates rollover availability for exchanging shares in one
entity for shares in another.
- ATO rulings explain that the rollover defers a capital gain until
disposal of replacement interests and outline conditions, including that
(apart from the rollover) a capital gain would have arisen.
Canada (s85.1 share‑for‑share and CRA Folio):
- CRA Folio S4‑F5‑C1 explains the rules for a share‑for‑share exchange
under ITA s85.1; for rollover, shares must be held as capital property
and consideration must be newly issued shares of the acquiring
corporation.
- ITA s85.1 provides statutory deeming rules for proceeds and cost when
the conditions apply.
Teach this as “not all capital‑markets events are disposals,” but they can change cost base and valuation.
Core lecture notes:
- A lock‑up is typically a contractual restriction on
sale post‑IPO; it usually does not itself transfer ownership, but it can
affect valuation evidence (discounts for lack of
marketability) in related‑party or non‑arm’s‑length settings. The
valuation framework you use is anchored in market value rules (UK s17;
Canada s69; Australia s116‑30).
- Pre‑IPO step transactions often include: converting preference shares,
implementing share consolidations/splits, exchanging shares under
takeover mechanics, or reorganizing shareholder classes. In the UK,
HS284 flags that share reorganizations (rights/bonus issues; takeover
issuances) may not be treated as acquisitions in the ordinary way and
points to specialist guidance.
Related‑party transfers:
- UK: market value rule for non‑arm’s‑length/connected
person disposals is explicitly statutory (TCGA s17) and explained in
HMRC manuals.
- Canada: ITA s69 is a central market‑value deeming
rule for non‑arm’s‑length/gifts and certain trust transfers.
- Australia: ITAA 1997 s116‑30 is the market value
substitution mechanism for non‑arm’s‑length capital proceeds.
Anti‑avoidance anchors (teach as “substance + purpose
overlays”):
- UK: Ramsay/Furniss line—courts can treat pre‑ordained
composite transactions as a whole for tax analysis. W.T. Ramsay Ltd
v IRC and Furniss v Dawson are canonical in the UK
step‑transaction/avoidance doctrine (often invoked in sophisticated
share exchange planning).
- UK statutory GAAR: Finance Act 2013 Part 5 introduces
the General Anti‑Abuse Rule for counteracting abusive tax arrangements.
- Canada GAAR: ITA s245 frames GAAR as counteracting
tax advantages from avoidance transactions resulting in misuse/abuse;
the Supreme Court’s Copthorne Holdings Ltd v Canada is a
leading GAAR case illustrating the “series of transactions” and abuse
inquiry.
- Australia GAAR (Part IVA): Australia’s GAAR is in
Part IVA of ITAA 1936; the High Court’s Commissioner of Taxation v
Hart is a leading “dominant purpose” case, frequently cited in
ATO materials discussing GAAR application.
Specific capital‑markets anti‑avoidance patterns:
- Wash sale / loss‑manufacturing: Australia has
published positions treating wash sale arrangements as tax avoidance—ATO
rulings and alerts explain how Part IVA can cancel tax benefits of
losses where economic exposure is not meaningfully changed.
- Canada “superficial loss” regime: ITA s54 defines
“superficial loss” around reacquisition in a 61‑day window (30 days
before/after disposition) by the taxpayer or affiliated persons, acting
as a statutory anti‑loss‑manipulation device.
- UK “bed and breakfast” matching: TCGA s106A addresses
rapid repurchase matching for fungible shares, preventing selective
realization strategies.
Capital markets frequently use nominee structures: the broker/custodian/nominee may be the registered holder while the investor is the beneficial owner.
UK principle (HMRC):
HMRC manuals state that gains accrue to the beneficial
owner, not the nominee, and that transferring legal
ownership between a nominee and beneficial owner does not constitute a
disposal for TCGA purposes.
Australia principle (statutory):
ITAA 1997 s104‑10(2) indicates a change of ownership (disposal) does not
occur if the taxpayer stops being the legal owner but continues to be
the beneficial owner—explicitly building beneficial ownership into CGT
event A1 analysis.
Instructor emphasis:
This is not just theory—beneficial ownership determines:
- the taxpayer who reports CGT; and
- whether certain custody movements are “real” disposals or just
back‑office transfers.
Use this as a “market infrastructure mini‑lecture,” then tie back to tax dates and documents.
Practical lesson link:
The clearing/settlement chain determines what evidence exists (trade
confirmations, contract notes, settlement statements, custodial
statements), which is crucial to record‑keeping and audit defense. HMRC
and CRA both emphasize record‑keeping and standardized reporting
mechanisms (SA108; Schedule 3; T5008).
This section frames “exemptions” broadly as (i) complete exclusions from CGT, (ii) participation‑type exemptions, (iii) deferral rollovers, and (iv) administrative safe harbors for liquid markets.
UK: Substantial Shareholding Exemption (SSE) (corporate exemption
framework)
- TCGA 1992 Schedule 7AC provides that certain gains accruing to a
company on disposal of shares are not chargeable gains if Schedule
requirements are met.
- HMRC manuals describe SSE operation and scope.
Australia: foreign resident portfolio‑style exclusion for non‑TAP
assets
- ITAA 1997 Division 855 generally allows foreign residents to disregard
capital gains/losses unless the CGT asset is “taxable Australian
property.”
- ATO guidance explains an indirect interest in Australian real property
exists if both (i) a 10%+ non‑portfolio interest test and (ii) a
principal asset test are satisfied.
Canada: “excluded property” for s116 administration (market
liquidity safe harbor)
Canada’s s116 is a non‑resident disposition compliance mechanism. But it
also contains a powerful “liquidity” carve‑out: excluded
property includes many listed securities and mutual fund
units.
- ITA s116(6) defines excluded property to include a security listed on
a recognized stock exchange (among other items), plus units of a mutual
fund trust and certain debt obligations.
- For non‑resident dispositions of taxable Canadian property that is not
excluded property, s116 creates notice requirements and purchaser
liability rules.
Canada:
- Share‑for‑share rollover: CRA Folio S4‑F5‑C1 and ITA s85.1 provide the
rollover architecture.
- Capital gains deduction is an important “relief” tool for individuals;
CRA describes capital gains deduction on line 25400 and identifies
eligible property types.
- CRA’s CG guide also defines “small business corporation” in part by a
90%+ asset use test in active business contexts, which becomes relevant
for qualifying shares and deductions/deferrals in planning.
Australia:
- Scrip‑for‑scrip rollover is the principal takeover/exchange deferral
tool (Subdivision 124‑M).
UK:
- Share reorganization/takeover rules appear in the Self Assessment CG
helpsheet ecosystem; HS284 is the learners’ “field manual” for basic
share disposals and identification rules.

These templates are designed to be jurisdiction‑adaptable. Replace bracketed text with local statutory citations and forms.
Purpose: Ensure you can compute and defend CGT outcomes from broker/exchange data.
A. Trade and settlement evidence (request from
broker/custodian)
- Trade confirmations / contract notes (include trade date/time,
instrument identifiers, quantity, price, fees).
- Settlement statements or post‑trade confirmations showing settlement
date and delivered quantity.
- Year‑end transaction history (CSV if possible) and realized/unrealized
gain summary (if broker produces it).
- Corporate action statements (splits, consolidations, takeovers, scrip
distributions).
- Custody statements identifying nominee structure and beneficial owner
designation. (Nominee vs beneficial ownership matters for “who is
taxed.” )
B. Tax authority reporting reconciliation
- Canada: T5008 slips and issuer statements (remember:
T5008 is filed for purchases/sales including as agent/nominee).
- UK: SA108 CG pages and computations worksheet
evidence retention expectations.
- Australia: document any third‑party reported
securities transaction data available and reconcile to taxpayer records
(ATO indicates share market transaction data‑matching programs).
C. Red flags / “audit magnets”
- Rapid sell→repurchase patterns (UK s106A matching; Canada superficial
loss; Australia wash sales).
- Related‑party transfers or non‑arm’s‑length pricing (UK s17; Canada
s69; Australia s116‑30).
- Unlisted shares with weak valuation support (HMRC SAV; CRA IC 89‑3).
Subject: Capital Gains Tax considerations – disposal of shares in [Issuer]
Facts provided
- Taxpayer: [name/entity; residency]
- Shares: [class; ISIN/CUSIP; listed/unlisted]
- Disposal method: [exchange trade / private sale / buy‑back / share
exchange]
Issues
1) Who is the disposing person (beneficial owner vs nominee)?
2) What is the disposal date for CGT?
3) How is base cost computed and which share identification rules
apply?
4) Are any rollovers/exemptions available?
5) Any anti‑avoidance concerns?
Analysis framework (insert jurisdiction)
- UK: disposal under contract → contract date (TCGA
s28). Use Section 104 pooling and s106A matching where relevant.
- Australia: CGT event A1; time = contract date; no
disposal if only legal ownership changes and beneficial owner unchanged.
- Canada: dispositions reportable on Schedule 3;
reconcile T5008; consider superficial loss rules for repurchases; for
non‑arm’s‑length pricing apply s69.
Documentation required
[List items using broker reporting checklist]
Conclusion / action list
- Confirm ownership/timing.
- Gather documents.
- Compute gain/loss and file on appropriate return (SA108 / annual
return / Schedule 3).
Subject: Request for valuation package – unlisted shares in [Company] for CGT reporting
Please provide the following to support a defensible fair market value /
market value position:
- Cap table and share rights (preference/liquidation preference,
convertibility, veto rights).
- Latest financial statements and management accounts.
- Forecasts (if used) and assumptions.
- Recent arm’s‑length transactions in the shares and term sheets.
- Comparable companies / precedent deal set (if used).
- Details of restrictions (ROFR, drag/tag, lock‑ups) and their valuation
treatment.
- Valuation report stating methodology and conclusion. Use
jurisdictional standards:
- Canada: valuation approaches consistent with CRA IC 89‑3 policy
statement.
- UK: statutory “open market” concept used in HMRC valuation framework
(SAV guidance).
- Australia: valuation must be objective and supportable; market value
substitution may apply for non‑arm’s‑length proceeds.
Placement: Prospectus / offering memorandum – “Taxation” section (high‑level, non‑advice language)
Draft (adapt):
“Investors should note that the tax consequences of acquiring, holding,
and disposing of Shares may vary depending on the investor’s
circumstances and jurisdiction. Certain restructures undertaken in
connection with the offering (including share reorganizations or
share‑for‑share exchanges) may be treated as tax‑deferred in some
jurisdictions if statutory conditions are met, while in other cases they
may be treated as disposals at market value. For example, in the UK,
share exchange and reorganization rules may apply to qualifying
exchanges and HMRC operates clearance procedures in certain contexts; in
Australia, scrip‑for‑scrip rollover may defer gains on qualifying
exchanges; and in Canada, share‑for‑share rollover relief may apply
under section 85.1 if conditions are met. Investors should obtain
independent tax advice.”
1) Under UK law, where an asset is disposed of under an unconditional
contract, the time of disposal is generally:
A. Settlement date
B. Registration date
C. The time the contract is made
D. The date the broker issues a statement
Answer: C.
2) In Australia, the time of CGT event A1 is:
A. Always settlement date
B. When you enter into the contract for disposal (or if no contract,
when change of ownership occurs)
C. When the stock exchange reports the trade to the regulator
D. When the tax return is filed
Answer: B.
3) HMRC guidance indicates that a transfer of legal ownership between a
nominee and the beneficial owner:
A. Always triggers CGT
B. Never triggers CGT and gains accrue to the nominee
C. Does not constitute a disposal for TCGA purposes; gains accrue to the
beneficial owner
D. Is taxed as employment income
Answer: C.
4) In Canada, traders or dealers in securities must file which
information return to report purchases and sales of securities
(including sales as agent/nominee)?
A. SA108
B. T1 General
C. T5008
D. NR03
Answer: C.
5) Which is a correct statement about Canada’s non‑resident disposition
compliance mechanism in ITA s116?
A. All securities require a certificate of compliance.
B. Listed securities on recognized stock exchanges can fall within
“excluded property,” reducing s116 friction for liquid markets.
C. Purchasers have no liability under s116.
D. s116 applies only to real property, never shares.
Answer: B.
1) Explain why capital markets create recurring confusion between “trade date” and “settlement date.” Provide one statutory anchor from the UK or Australia and one administrative anchor from Canada.
2) A founder sells unlisted shares to a related party at a discount shortly before an IPO. Identify the valuation/market‑value substitution rules that could apply in each of the UK, Australia, and Canada, and list the minimum valuation evidence you would request.
3) Compare the policy goals and mechanics of (a) UK “bed and breakfast” matching, (b) Canadian “superficial loss,” and (c) Australian wash sale anti‑avoidance approaches.
Scenario:
Ms. N holds 50,000 shares of Alpha plc (listed) acquired in three
tranches at different prices, and 15,000 shares of Beta Ltd (unlisted)
received on a 2‑for‑1 scrip exchange. She sells 20,000 Alpha shares and
repurchases 20,000 Alpha shares within 20 days. She later sells Beta Ltd
shares to her brother for a price significantly below an independent
valuation.
You are asked to advise (comparatively) for UK, Australia, and
Canada:
1) What is the likely disposal date for the Alpha trade?
2) What identification / loss‑limitation rule could apply to the Alpha
sale and repurchase?
3) What pricing rule likely applies to the Beta related‑party
sale?
4) What documents are required to support compliance?
Model answer (high-level but rigorous):
1) Alpha disposal date:
- UK: time of disposal under contract is contract date (trade date in
practice).
- Australia: time of CGT event A1 is contract date.
- Canada: CRA position often treats settlement date as the date of
disposition for exchange trades (teach as a Canada‑specific rule to
verify and document).
2) Alpha repurchase anti‑loss/identification
controls:
- UK: apply the “bed and breakfasting” identification regime (TCGA
s106A) and Section 104 pooling; the disposal may be matched with
acquisition within the relevant statutory window rather than the pool.
- Canada: superficial loss rules (ITA s54) may deny or defer the loss if
reacquisition occurs within the prescribed window by the taxpayer or an
affiliated person.
- Australia: consider wash sale anti‑avoidance where economic exposure
is effectively retained and the arrangement is designed to create
losses; ATO guidance links wash sales to Part IVA.
3) Beta related‑party pricing:
- UK: TCGA s17 market value rule applies where disposal is not a bargain
at arm’s length.
- Australia: market value substitution rule (s116‑30) can replace
proceeds with market value for non‑arm’s‑length events.
- Canada: ITA s69 deems proceeds to fair market value for
non‑arm’s‑length dispositions for less than FMV or gifts.
4) Documents:
- Alpha: broker confirmations, settlement statements, corporate action
statements; apply jurisdictional identification rules (HS284 in UK,
T5008 in Canada where relevant).
- Beta: independent valuation package consistent with CRA IC 89‑3/UK SAV
framework/Australian valuation guidance; share exchange documentation to
assess rollover eligibility and cost base continuity.
