Structured Notes Tax Treatment: Key Tax Considerations for International Investors

Consequently, internationally mobile investors should thoroughly examine their specific positions and circumstances to devise a tax-optimisation plan tailored to their circumstances.

To assist in doing so, this article explains the fundamentals of structured notes’ tax treatment and explores the crucial considerations for expat investors, including how product features, cross-border withholding rules, and changes in tax residency can influence the ultimate tax outcome.

How Are Structured Notes Taxed Across Jurisdictions?

There is no universal tax rule that applies to structured notes. Even within a single jurisdiction, the notes’ tax treatment can vary significantly depending on how the note is structured and how the related income is recognised.

Different jurisdictions may also classify the same instrument differently, which can affect both the character of the return (for example, interest versus capital gain) and the timing of taxation.

For instance, structured notes are often treated as debt instruments with contingent payments in the US, triggering stringent tax rules.

Specifically, many structured notes are treated as Contingent Payment Debt Instruments (CPDIs), so they are taxed under the corresponding regulations.

The IRS assumes the note will yield a specific rate (a “comparable yield”) and requires investors to accrue taxable income each year, even if no cash is paid out during that year.

This phenomenon is colloquially referred to as “phantom income,” and US investors may face annual tax on estimated interest that they have not actually received.

At maturity or redemption, the overall return on CPDI-treated notes is generally taxed largely as ordinary income rather than as capital gain, with taxation occurring at the investor’s marginal rate.

The UK has a broadly comparable analytical approach but applies different rules, focusing on whether returns are treated as genuine investment gains or as “disguised interest.” To arrive at this decision, HM Revenue & Customs (HMRC) typically relies on three factors:

1. Whether the return is essentially compensation for the time value of money
2. Whether it is comparable to a normal interest rate
3. Whether there is a practical likelihood that the return will be paid under the product’s terms

If these conditions are met, the structured note’s returns are deemed interest and taxed according to the individual’s marginal rate.

If the return does not meet the disguised interest criteria, the tax outcome will depend on the legal structure of the instrument and may fall within capital gains tax or other applicable regimes.

Why Issuer Documentation and Tax Classification Matter

In practice, the tax treatment of a structured note is often influenced by how the issuer classifies the instrument in its offering documentation.

While this classification is not legally binding on investors or tax authorities, it frequently determines how income is reported and how tax authorities initially interpret the instrument.

Most structured notes are accompanied by detailed tax disclosures in documents such as:

• The prospectus or offering memorandum
• Pricing supplements
• Tax supplements or information statements
• Annual tax reporting forms provided by the issuer or broker

These materials typically outline the issuer’s intended tax treatment of the product. For instance, a note may be described as:

• A contingent payment debt instrument (CPDI)
• A prepaid forward contract
• A derivative or option-based instrument
• A debt instrument with periodic interest payments

This classification affects how income is reported to investors and tax authorities. In the United States, for example, issuers may report income under regimes such as CPDI or Original Issue Discount (OID), which can require investors to recognise income annually even if no cash is received.

However, investors should understand that the issuer’s intended treatment does not automatically determine the investor’s tax outcome.

Local tax authorities may apply their own classification rules, particularly when the investor resides in a different jurisdiction than the issuer.

For internationally mobile investors, this can create complications. The issuer may report income under one framework while the investor’s country of residence applies a different classification. Such discrepancies can affect:

• The timing of taxable income
• Eligibility for foreign tax credits
• The characterisation of income as interest or capital gains

As a result, reviewing the tax section of the offering documentation is a critical step before investing in a structured note. It provides insight into how the issuer expects the product to be taxed and highlights potential areas of uncertainty for cross-border investors.

How the Characterisation of the Notes’ Returns Impact Their Taxation

Considering that no jurisdiction has a dedicated approach to the taxation of structured notes, your primary consideration should be how the return is characterised, namely the following three options:

1. Ordinary income
2. Capital gain
3. Periodic accrual

Ordinary Income

If the return from a structured note is considered ordinary income, it will generally be taxed at regular income tax rates in the year the return is received. For instance, a 5% coupon paid annually is usually treated as interest income in that year.

This is often less favourable from a tax-efficiency perspective because:

• The marginal rate of HNWIs is typically high
• There is no tax deferral (considering that tax is due in the same year when income is received)
• You cannot utilise preferential rates as you would for capital gains

If you are in the US, you may encounter additional complexity due to the note’s classification as a Contingent Payment Debt Instrument (CPDI).

Under CPDI rules, investors must accrue taxable income annually based on the note’s projected yield, even if the note pays no interest until maturity.

Although there are adjustment mechanisms to correct any discrepancies, such uncertainty can complicate financial planning.

Capital Gain

Structured notes treated as capital assets generally incur capital gains tax upon sale, exchange, or maturity, rather than being taxed annually as ordinary income.

However, this treatment typically applies only when the note is not classified as a debt instrument for tax purposes and instead resembles a derivative or investment contract.

One of the primary determinants of the tax treatment in certain jurisdictions, particularly the United States, is the holding period:

The holding period can make a difference between taxation at your marginal rate and at your jurisdiction’s CGT rate in jurisdictions that distinguish between short-term and long-term gains. Consequently, in such jurisdictions, it may be beneficial to time the disposal of the note accordingly.

Any contingent coupons received during the term are still taxed as ordinary income. You may only leverage the preferential rate upon disposing of the note.

Furthermore, there are scenarios in which portions of long-term capital gains may be recharacterised as ordinary income, such as when the note is treated as a constructive ownership transaction.

It is also important to note that not all jurisdictions apply different capital gains tax rates based on holding period. For example, the UK generally taxes capital gains at the same rate regardless of whether the asset is held for one year or longer.

Understanding such scenarios and classifying income accordingly is complex and requires extensive knowledge of the related tax regulations. If you need assistance, Titan Wealth International can provide personalised guidance and devise an effective tax optimisation strategy.

Periodic Accruals

Accrual-based taxation of structured notes commonly arises under the US Contingent Payment Debt Instrument (CPDI) and Original Issue Discount (OID) regimes, under which you pay taxes annually on income that has been earned or “imputed” but not yet received in cash (the aforementioned phantom income).

For OID accruals, the IRS may assign “imputed interest” that must be reported annually, based on the instrument’s yield, regardless of actual performance. Reporting is performed through Form 1099-OID, 1099-INT, or 1099-B, which often require supplemental, complex tax reporting.

If the actual return is higher or lower than the sum of accrued amounts, that difference is taken into account depending on its nature (e.g., as additional ordinary income, a loss, or an adjustment).

The effect of accrual taxation is the acceleration of tax and the potential for a mismatch, requiring you to pay tax before you receive the funds.

This outcome is particularly relevant for internationally mobile investors, as a change in tax residency during the term of the note may result in different jurisdictions taxing different portions of the accrued income.

How Do Note Features Impact Tax Outcomes?

The complexity of structured notes stems from the many variances in their design. To understand the related tax implications, you must consider specific note features, most notably:

1. Coupon payments
2. Principal protection
3. Buffers and barriers
4. Autocall provisions

Coupon Payments

The presence of regular coupon payments determines both the timing and nature of a note’s taxation.

Coupon-paying notes (e.g., fixed coupon notes or reverse convertible notes) provide returns during their term, although these payments are typically taxed as income in the year they are received or deemed received under local tax rules.

For instance, if you invest in a reverse convertible note receiving a 12% annual coupon on $500,000 (i.e. $60,000 per year), you must report that entire coupon payment as ordinary income.

Similarly, in the UK, any periodic coupon from a note is typically taxed as interest (savings income) in the tax year it is paid.

By contrast, notes without periodic coupons (typically referred to as growth notes) accumulate their returns and pay them at maturity, so they may be more tax-efficient where local rules allow taxation to occur only on redemption rather than during the term of the investment.

For instance, an equity-linked growth note in the US may be structured to qualify as a prepaid forward contract, so that all tax is deferred until maturity as capital gain. However, the IRS may intervene by applying the CPDI rules to impose annual phantom income instead.

If you can avoid such scenarios, you may not have to pay tax until you actually receive the funds. You may also leverage a lower rate on the final gain by paying CGT rather than personal income tax in jurisdictions that apply preferential capital gains rates.

Principal Protection

The presence of principal protection tends to increase the likelihood that a note will be taxed under interest-based rules, because principal-protected notes typically contain an embedded bond component, which makes their returns appear economically similar to interest.

Tax authorities frequently treat these notes as interest-bearing investments because the payoff is akin to obtaining your deposit back plus interest.

While the specific rules differ between jurisdictions, principal protection often increases the probability that the return will be treated as interest-like income.

• US: Many principal-protected structured notes are treated as debt instruments and may fall within the Original Issue Discount (OID) or Contingent Payment Debt Instrument (CPDI) regimes, under which the IRS assigns an implicit interest rate to the note and taxes it accordingly.
• UK: If a note guarantees your capital and offers a fixed uplift (or a highly likely contingent uplift), HMRC will likely deem that uplift interest income.

Conversely, capital-at-risk notes are sometimes more likely to receive capital-gains-type treatment, because exposing the principal to risk can make the investment resemble an equity-linked instrument rather than a fixed-income product.

Adding tangible downside risk can help align note returns with capital gains. You may deliberately decide to invest in notes with a certain degree of risk to achieve better tax outcomes. However, tax implications should not be your primary consideration when defining your risk tolerance.

Buffers and Barriers

In contrast to complete principal protection, buffers and barriers (floors) provide a certain degree of security. As such, they affect taxation to the extent that they may protect the principal.

For instance, a barrier may provide principal protection if the underlying investment falls up to 30%. The “deeper” the barrier, the less likely it is that the trigger event will occur, which makes a structured note more risk-free.

In such a case, the tax authority might argue the note’s returns are effectively predetermined interest. A modest buffer or shallow barrier (e.g., a 10% buffer) means even a moderate market shift will affect the payout, supporting the view that the returns are more uncertain.

For a note to receive capital-like treatment, it should have multiple contingent scenarios, such as:

• Coupons that cancel if a barrier is breached
• Capital loss if the underlying investment falls sufficiently
• Sufficient volatility that results in variability in the outcome

In the US, buffer and barrier notes are typically issued as debt instruments, so the IRS treats the contingent outcomes under the CPDI framework. A schedule of possible outcomes is utilised to project an “expected” return each year, resulting in annual phantom income taxation.

Autocall Provisions

Autocallable structured notes automatically redeem early if specific performance conditions are met. For instance, a note might terminate after one year if an underlying index reaches a predetermined level, and it would pay back the principal, along with a coupon for the given year.

Consequently, an autocall provision primarily determines the timing of the taxable event, which in turn may influence the return’s characterisation depending on the jurisdiction and the tax classification of the note.

For notes treated as debt instruments (for example, under US CPDI rules), the return may already be taxed annually through accrual mechanisms, meaning the autocall mainly affects the final settlement and adjustment of previously accrued income.

Where a structured note is instead treated as a capital asset, the timing of the autocall may influence when the gain is recognised and, in certain jurisdictions such as the United States, whether the gain is considered short-term or long-term.

Given that any gain is recognised in the tax year in which the note autocalls, you may face additional uncertainty regarding its tax treatment. It is therefore advisable to plan for all potential scenarios when estimating your tax obligations.

Tax Implications of Selling Structured Notes Before Maturity

Although structured notes are frequently held until maturity, investors may choose to sell them earlier in the secondary market. Early disposal can materially change the tax treatment of the investment.

When a structured note is sold before maturity, the investor typically realises a gain or loss equal to the difference between the sale proceeds and the investor’s tax basis in the note.

However, determining the correct tax treatment can be complex because structured notes often contain both interest and capital components.

In some jurisdictions, the proceeds from a secondary market sale must be divided into different categories of income. For example:

• Accrued interest or imputed income may be taxed as ordinary income
• The remaining portion of the gain may be treated as a capital gain

In the United States, investors holding notes treated as Contingent Payment Debt Instruments (CPDIs) must adjust their tax basis each year to reflect previously accrued income. When the note is sold, the final gain or loss must be calculated using these adjusted amounts.

For internationally mobile investors, the situation can become even more complicated if the sale occurs after a change in tax residency. The country where the note is sold may apply different rules from the jurisdiction where the investment was originally purchased. This can affect:

• The classification of the gain
• The availability of foreign tax credits
• The timing of taxable income

Consequently, investors who anticipate selling a structured note before maturity should evaluate the potential tax consequences in advance, particularly if they expect their tax residency to change during the investment period.

What Should Expats Consider Before Investing in Structured Notes

The primary consideration for expat investors is the enhanced tax complexity of structured notes across jurisdictions. Rather than solely adhering to domestic rules (which are typically quite complex), you must also understand how your current or future country of residence will treat the income derived from notes.

Considering that many jurisdictions may treat at least part of a structured note’s return as interest, withholding tax may apply when a structured note pays a coupon or interest component from one country to an investor in another.

However, the applicable withholding tax rate depends on the source of the payment, local tax law, and any applicable tax treaty.

For example, certain jurisdictions apply statutory withholding taxes on cross-border interest payments, although exemptions or treaty reductions may apply:

Double tax agreements (DTAs) may reduce or eliminate withholding tax, so it is critical to familiarise yourself with the relevant provisions.

Furthermore, you may have to pay tax once the return reaches you in your current country of residence. Even where withholding tax is applied, the income may still be taxable in the investor’s country of residence, with relief typically provided through foreign tax credits under applicable tax treaties.

Although income characterisation is typically aligned across jurisdictions, inconsistencies can introduce significant tax complications.

For instance, if one country characterises returns as interest but another jurisdiction treats them as capital gains, the withholding tax might not be creditable against the capital gains tax because they are different income categories.

Such nuances can make cross-border structured note taxation particularly complex, so it is highly recommended to consult a tax professional before making significant investments.

Dividend Equivalent Withholding on Equity-Linked Notes

Structured notes linked to equities can introduce additional withholding tax considerations for international investors.

In particular, notes referencing US equities or equity indices may fall within the scope of the United States’ dividend equivalent withholding rules under Internal Revenue Code Section 871(m).

These rules are designed to prevent non-US investors from replicating the economic effect of receiving dividends through derivative instruments without paying withholding tax.

Under the regulations, certain payments made on equity-linked instruments may be treated as “dividend equivalents.”

If a structured note falls within the scope of these rules, a portion of the return may be treated as a dividend equivalent payment even if the note does not distribute actual dividends.

For non-US investors, these amounts may be subject to US withholding tax of up to 30%, although applicable tax treaties may reduce this rate.

Whether a structured note triggers dividend equivalent withholding depends on factors such as:

• The reference asset (for example, US equities or equity indices)
• The delta or sensitivity of the instrument to the underlying stock
• The structure of the payoff

Many widely distributed structured notes are designed to fall outside the scope of these rules, but the analysis can be technical and depends on the specific product design.

For expat investors purchasing notes linked to US equities, it is therefore important to review the issuer’s disclosure regarding Section 871(m) and understand whether dividend equivalent withholding may apply.

Foreign Exchange Taxation and Currency Effects

For internationally mobile investors, the currency denomination of a structured note can introduce additional tax considerations.

Structured notes are commonly issued in major currencies such as US dollars, euros, or pounds sterling, but an investor’s tax liabilities are generally calculated in the currency of their country of tax residence.

As a result, movements in exchange rates can create taxable gains or losses independent of the note’s investment performance.

For example, an investor who purchases a USD-denominated structured note while resident in the UK may experience a gain or loss when converting the proceeds back into pounds at maturity.

Even if the investment produces no economic profit in US dollar terms, exchange rate movements can generate a taxable gain when measured in sterling.

Different jurisdictions apply different rules to such foreign exchange movements. In some cases, currency gains are treated as part of the overall capital gain on the investment.

In others, foreign exchange movements may be taxed separately as income or as a distinct category of gain.

For expat investors who frequently move between countries, the impact of currency movements can be particularly significant if the investment is acquired in one tax jurisdiction and redeemed in another. Changes in tax residency may alter both:

• The tax treatment of foreign exchange gains, and
• The currency used to calculate taxable income

Consequently, investors should consider the currency denomination of structured notes as part of their broader tax planning strategy, particularly when investing across multiple jurisdictions.

Cross-Border Reporting Obligations for Structured Notes

For internationally mobile investors, the tax treatment of structured notes is only one part of the compliance picture.

Many jurisdictions impose reporting requirements for foreign financial assets, and structured notes held through international brokers or banks may fall within the scope of these rules.

For example, investors who are considered US persons for tax purposes may be required to disclose foreign financial assets, including structured notes held outside the United States, under reporting regimes such as Foreign Bank Account Reporting (FBAR) and Form 8938 (Statement of Specified Foreign Financial Assets).

These rules can apply even when the underlying investment does not generate taxable income during the year.

Similarly, residents of other jurisdictions may need to report offshore investments through their local tax filings.

In the UK, for instance, individuals must generally disclose income or gains from structured notes through the Self Assessment system when the investment is held outside tax-advantaged accounts.

In addition, structured notes held through international financial institutions are often subject to automatic information exchange frameworks, including the Common Reporting Standard (CRS) and the Foreign Account Tax Compliance Act (FATCA).

Under these systems, financial institutions report account information to tax authorities, which may then share the data with the investor’s country of tax residence.

For expat investors, these reporting regimes can create compliance obligations across multiple jurisdictions.

Even where the tax liability is limited, failing to report foreign financial assets correctly may result in penalties. As a result, investors should ensure that their structured note holdings are properly disclosed in all relevant tax filings.

What Happens if You Change Tax Residency During a Note’s Term?

Changing your tax residency during a structured note’s term can have several notable consequences, including:

• Exit taxes and deemed disposals: Some jurisdictions impose exit taxes or treat certain assets as having been disposed of when an individual ceases to be a tax resident. For example, the United States applies expatriation tax rules to certain high-net-worth individuals who renounce citizenship or long-term residency. Consequently, you may need to value the structured note at exit and include any accrued gain in that year’s tax filing. However, not all countries apply a general exit tax when individuals leave; the specific treatment depends on the jurisdiction and the investor’s circumstances.
• Temporary non-residence rules: Some countries, such as the UK, impose temporary non-residence rules that allow them to tax specific income or gains realised during a period of non-residence if the individual returns within a defined timeframe. If your note matures abroad, you must assess whether such rules apply to you to prevent excessive taxation. In the UK, these rules can apply where an individual was resident for several years prior to departure and returns to the UK within five tax years.
• Taxation discrepancies: If you relocate from a low- or territorial-tax country (e.g. the UAE) to a high-tax country, your structured note could transition from lightly taxed to fully taxable on worldwide income.

In addition, a change in tax residency may affect how previously accrued income is treated. Some jurisdictions may tax income on an accrual basis, while others tax gains only upon redemption or disposal, which can result in different countries taxing different portions of the same return.

The specific scenarios you may encounter can vary markedly due to the numerous factors influencing structured note taxation, making it difficult to predict them without adequate guidance.

It is crucial to prepare for any relocation (or repatriation) with a complete understanding of its tax consequences.
