The following is a summary, under current law (unless otherwise noted) and the current published practice of HM Revenue and Customs ('HMRC'), of certain UK tax considerations that are likely to be material to the ownership and disposition of HSBC Holdings ordinary shares. The summary does not purport to be a comprehensive description of all the tax considerations that may be relevant to a holder of shares. In particular, the summary deals with shareholders who are resident solely in the UK for UK tax purposes and only with holders who hold the shares as investments and who are the beneficial owners of the shares, and does not address the tax treatment of certain classes of holders such as dealers in securities. Holders and prospective purchasers should consult their own advisers regarding the tax consequences of an investment in shares in light of their particular circumstances, including the effect of any national, state or local laws.

Taxation of dividends

Currently, no tax is withheld from dividends paid by HSBC Holdings.

UK resident individuals

UK resident individuals are generally entitled to a tax-free annual allowance in respect of dividends received. The amount of the allowance for the tax year beginning 6 April 2023 is £1,000. To the extent that dividend income received by an individual in the relevant tax year does not exceed the allowance, a nil tax rate will apply. Dividend income in excess of this allowance will be taxed at 8.75% for basic rate taxpayers, 33.75% for higher rate taxpayers and 39.35% for additional rate taxpayers.

UK resident companies

Shareholders that are within the charge to UK corporation tax should generally be entitled to an exemption from UK corporation tax on any dividends received from HSBC Holdings. However, the exemptions are not comprehensive and are subject to anti-avoidance rules.

If the conditions for exemption are not met or cease to be satisfied, or a shareholder within the charge to UK corporation tax elects for an otherwise exempt dividend to be taxable, the shareholder will be subject to UK corporation tax on dividends received from HSBC Holdings at the rate of corporation tax applicable to that shareholder. 

Taxation of capital gains

The computation of the capital gains tax liability arising on disposals of shares in HSBC Holdings by shareholders subject to UK tax on capital gains can be complex, partly depending on whether, for example, the shares were purchased since April 1991, acquired in 1991 in exchange for shares in The Hongkong and Shanghai Banking Corporation Limited, or acquired subsequent to 1991 in exchange for shares in other companies.

For capital gains tax purposes, the acquisition cost for ordinary shares is adjusted to take account of subsequent rights and capitalisation issues. Any capital gain arising on a disposal of shares in HSBC Holdings by a UK company may also be adjusted to take account of indexation allowance if the shares were acquired before 1 January 2018, although the level of indexation allowance that is given in calculating the gain would be frozen at the value that would have been applied to a disposal of those shares in December 2017. If in doubt, shareholders are recommended to consult their professional advisers.

Stamp duty and stamp duty reserve tax

Transfers of shares by a written instrument of transfer generally will be subject to UK stamp duty at the rate of 0.5% of the consideration paid for the transfer (rounded up to the next £5), and such stamp duty is generally payable by the transferee. An agreement to transfer shares, or any interest therein, normally will give rise to a charge to stamp duty reserve tax at the rate of 0.5% of the consideration. However, provided an instrument of transfer of the shares is executed pursuant to the agreement and duly stamped before the date on which the stamp duty reserve tax becomes payable, under

the current published practice of HMRC it will not be necessary to pay the stamp duty reserve tax, nor to apply for such tax to be cancelled. Stamp duty reserve tax is generally payable by the transferee.

Paperless transfers of shares within CREST, the UK's paperless share transfer system, are liable to stamp duty reserve tax at the rate of 0.5% of the consideration. In CREST transactions, the tax is calculated and payment made automatically. Deposits of shares into CREST generally will not be subject to stamp duty reserve tax, unless the transfer into CREST is itself for consideration. Until 31 December 2023, the charge to stamp duty reserve tax at 1.5% on the issue of shares (and transfers integral to capital raising) to a depositary receipt issuer or a clearance service was incompatible with European Union law as retained in the UK following the UK's departure from the European Union, and was not imposed by HMRC. If the UK Finance Bill 2023-24 is enacted in the form it stands as at the date hereof, that 1.5% charge will be repealed with retrospective effect from 1 January 2024.

Taxation - US residents

The following is a summary, under current law, of the principal UK tax and US federal income tax considerations that are likely to be material to the ownership and disposition of shares or American Depositary Shares ('ADSs') by a holder that is a US holder, as defined below, and who is not resident in the UK for UK tax purposes.

The summary does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a holder of shares or ADSs. In particular, the summary deals only with US holders that hold shares or ADSs as capital assets, and does not address the tax treatment of holders that are subject to special tax rules. These include banks, tax-exempt entities, insurance companies, dealers in securities or currencies, persons that hold shares or ADSs as part of an integrated investment (including a 'straddle' or 'hedge') comprised of a share or ADS and one or more other positions, and persons that own directly or indirectly 10% or more (by vote or value) of the stock of HSBC Holdings. This discussion is based on laws, treaties, judicial decisions and regulatory interpretations in effect on the date hereof, all of which are subject to change.

For the purposes of this discussion, a 'US holder' is a beneficial holder that is a citizen or resident of the United States, a US domestic corporation or otherwise is subject to US federal income taxes on a net income basis in respect thereof.

Holders and prospective purchasers should consult their own advisers regarding the tax consequences of an investment in shares or ADSs in light of their particular circumstances, including the effect of any national, state or local laws.

Any US federal tax advice included in the Annual Report and Accounts 2023 is for informational purposes only. It was not intended or written to be used, and cannot be used, for the purpose of avoiding US federal tax penalties.

Taxation of dividends

Currently, no tax is withheld from dividends paid by HSBC Holdings. For US tax purposes, a US holder must include cash dividends paid on the shares or ADSs in ordinary income on the date that such holder or the ADS depositary receives them, translating dividends paid in UK pounds sterling into US dollars using the exchange rate in effect on the date of receipt. A US holder that elects to receive shares in lieu of a cash dividend must include in ordinary income the fair market value of such shares on the dividend payment date, and the tax basis of those shares will equal such fair market value.

Subject to certain exceptions for positions that are held for less than 61 days, and subject to a foreign corporation being considered a 'qualified foreign corporation' (which includes not being classified for US federal income tax purposes as a passive foreign investment company), certain dividends ('qualified dividends') received by an individual US holder generally will be subject to US taxation at preferential rates.

Based on the company's audited financial statements and relevant market and shareholder data, HSBC Holdings does not believe that it was a passive investment company for its 2023 taxable year and does not anticipate becoming a passive foreign investment company in 2024 or the foreseeable future. Accordingly, dividends paid on the shares or ADSs generally should be eligible for qualified dividends treatment.

Taxation of capital gains

Gains realised by a US holder on the sale or other disposition of shares or ADSs normally will not be subject to UK taxation unless at the time of the sale or other disposition the holder carries on a trade, profession or vocation in the UK through a branch or agency or permanent establishment and the shares or ADSs are or have been used, held or acquired for the purposes of such trade, profession, vocation, branch or agency or permanent establishment. Such gains will be included in income for US tax purposes, and will be long-term capital gains if the shares or ADSs were held for more than one year. A long-term capital gain realised by an individual US holder generally will be subject to US tax at preferential rates.

Inheritance tax

Shares or ADSs held by an individual whose domicile is determined to be the US for the purposes of the United States-United Kingdom Double Taxation Convention relating to estate and gift taxes (the 'Estate Tax Treaty') and who is not for such purposes a national of the UK will not, provided any US federal estate or gift tax chargeable has been paid, be subject to UK inheritance tax on the individual's death or on a lifetime transfer of shares or ADSs except in certain cases where the shares or ADSs (i) are comprised in a settlement (unless, at the time of the settlement, the settlor was domiciled in the US and was not a national of the UK), (ii) are part of the business property of a UK permanent establishment of an enterprise, or (iii) pertain to a UK fixed base of an individual used for the performance of independent personal services. In such cases, the Estate Tax Treaty generally provides a credit against US federal tax liability for the amount of any tax paid in the UK in a case where the shares or ADSs are subject to both UK inheritance tax and to US federal estate or gift tax.

Stamp duty and stamp duty reserve tax - ADSs

If shares are transferred to a clearance service or American Depositary Receipt ('ADR') issuer (which will include a transfer of shares to the depositary) UK stamp duty and/or stamp duty reserve tax will be payable unless the UK Finance Bill 2023-24 is enacted in the form it stands as at the date hereof and the transfer is, or is treated as being, in the course of a capital raising arrangement. The stamp duty or stamp duty reserve tax is generally payable on the consideration for the transfer and is payable at the aggregate rate of 1.5%.

The amount of stamp duty reserve tax payable on such a transfer will be reduced by any stamp duty paid in connection with the same transfer.

No stamp duty will be payable on the transfer of, or agreement to transfer, an ADS, provided that the ADR and any separate instrument of transfer or written agreement to transfer remain at all times outside the UK, and provided further that any such transfer or written agreement to transfer is not executed in the UK. No stamp duty reserve tax will be payable on a transfer of, or agreement to transfer, an ADS effected by the transfer of an ADR.

US information reporting and backup withholding tax

Distributions made on shares or ADSs and proceeds from the sale of shares or ADSs that are paid within the US, or through certain financial intermediaries to US holders, are subject to US information reporting and may be subject to a US 'backup' withholding tax. General exceptions to this rule happen when the US holder: establishes that it is a corporation (other than an S corporation) or other exempt holder; or provides a correct taxpayer identification number, certifies that no loss of exemption from backup withholding has occurred and otherwise complies with the applicable requirements of the backup withholding rules. Holders that are not US persons (as defined in the US Internal Revenue Code of 1986, as amended) generally are not subject to US information reporting or

backup withholding tax, but may be required to comply with applicable certification procedures to establish that they are not US persons in order to avoid the application of such US information reporting requirements or backup withholding tax to payments received within the US or through certain financial intermediaries.

Approach to ESG reporting

The information set out in the ESG review on pages 41 to 98, taken together with other information relating to ESG issues included in this Annual Report and Accounts 2023, aims to provide key ESG information and data relevant to our operations for the year ended 31 December 2023. The data is compiled for the financial year 1 January to 31 December 2023 unless otherwise specified. Measurement techniques and calculations are explained next to data tables where necessary. There are no significant changes from the previous reporting period in terms of scope, boundary or measurement of our reporting of ESG matters. Where relevant, rationale is provided for any restatement of information or data that has been previously published. We have also considered our obligations under the Environmental, Social and Governance Reporting Guide contained in Appendix C2 to The Rules Governing the Listing of Securities on the Stock Exchange of Hong Kong Limited ('ESG Guide') and under LR9.8.6R(8) of the Financial Conduct Authority's ('FCA') Listing Rules. We will continue to develop and refine our reporting and disclosures on ESG matters in line with feedback received from our investors and other stakeholders, and in view of our obligations under the ESG Guide and the FCA's Listing Rules.

ESG Guide

We comply with the 'comply or explain' provisions in the ESG Guide, save for certain items, which we describe in more detail below:

-     A1(b) on relevant laws/regulations relating to air and greenhouse gas emissions, discharges into water and land, and generation of hazardous and non-hazardous waste, and on emissions: taking into account the nature of our business, we do not believe that there are relevant laws and regulations in these areas that have significant impacts on our operations. Nevertheless, we are fully compliant with our publication of information regarding scope 1 and 2 carbon emissions, while we only partially publish information on scope 3 carbon emissions, as the data required for that publication is not yet fully available.

-     A1.3 on total hazardous waste produced, A1.4 on total non-hazardous waste produced: Taking into account the nature of our business, we do not consider hazardous waste to be a material issue for our stakeholders. As such, we report only on total waste produced, which includes hazardous and non-hazardous waste.

-     A1.6 on handling hazardous and non-hazardous waste: Taking into account the nature of our business, we do not consider this to be a material issue for our stakeholders. Notwithstanding this, we continue to focus on the reduction and recycling of all waste. Building on the success of our previous operational environmental strategy, we are continuing to seek to identify key opportunities where we can lessen our wider environmental impact, including waste management. For further details, please see our ESG review on page 63.

-     A2.4 on sourcing water issue and water efficiency target: Taking into account the nature of our business, we do not consider this to be a material issue for our stakeholders. Notwithstanding this, we have implemented measures to further reduce water consumption through the installation of flow restrictors, auto-taps and low or zero flush sanitary fittings and continue to track our water consumption.

-     A2.5 on packaging material, B6(b) on issues related to health and safety and labelling relating to products and services provided, B6.1 on percentage of total products sold or shipped subject to recalls for safety and health reasons and B6.4 in recall procedures: Taking into account the nature of our business, we do not consider these to be material issues for our stakeholders.

This is aligned with the materiality reporting principle that is set out in the ESG Guide. See 'How we decide what to measure' on page 43 for further information on how we determine what matters are material to our stakeholders.

TCFD recommendations and recommended disclosures

As noted on page 17, we have considered our 'comply or explain' obligation under both the UK's Financial Conduct Authority's Listing Rules and Sections 414 CA and 414CB of the UK Companies Act 2006, and confirm that we have made disclosures consistent with the TCFD Recommendations and Recommended Disclosures, including its annexes and supplemental guidance, save for certain items, which we summarise below:

Targets setting

Metrics and targets (c) relating to short-term targets: For financed emissions we do not plan to set 2025 targets. We set targets in line with the Net-Zero Banking Alliance ('NZBA') guidelines by setting 2030 targets. While the NZBA define 2030 as intermediate, we use different time horizons for climate risk management. We define short term as time periods up to 2025; medium term is between 2026 and 2035; and long term is between 2036 and 2050. In 2023, we disclose interim 2030 financed emissions targets for seven sectors comprising five on-balance sheet and two combined financed emissions targets, as we outline on page 18. For the shipping sector, we have taken a decision not to set a standalone financed emissions target. The decision follows a reduction in our exposure to the sector after the strategic sale of part of our European shipping portfolio. This aligns with NZBA guidelines on sector inclusion for target setting. We have now set combined on-balance sheet financed emissions and facilitated emissions targets for two emissions-intensive sectors: oil and gas, and power and utilities, and report the combined progress for both sectors. We intend to review the financed emissions baselines and targets annually and restate where relevant, to help ensure that they are aligned with market practice and current climate science. For further details on the restatements and targets and progress of financed emissions, see section 'Our approach to financed emissions recalculations' and 'Targets and Progress' on page 56 and 57.

Metrics and targets (c) relating to capital deployment target: We do not currently disclose a target for capital deployment. In relation to capital deployment, since 2015, we have issued more than $2bn of our own green bonds and structured green bonds with the capital invested into a variety of green projects, including: green buildings, renewable energy and clean transportation projects. In 2023, we further progressed our internal review and enhancement of the green bond framework, with further refinement including internal and external review to be undertaken in 2024. This will be subject to continuous review and monitoring to ensure that they remain up to date and reflect updated standards, taxonomies and best practices. Any such developments in standards, taxonomies and best practices over time could result in revisions in our reporting going forward and lead to differences year-on-year as compared to prior years. See the HSBC Green Bond Report for further information.

Metrics and targets (c) relating to internal carbon pricing target: We do not currently disclose internal carbon pricing target due to transitional challenges such as developing the appropriate systems and processes, but we considered carbon prices as an input for our climate scenario analysis exercise. We expect to further enhance the disclosure in the medium term as more data becomes available.

Impacts on financial planning and performance

Strategy (b) relating to financial planning and performance: We have used climate scenarios to inform our organisation's business, strategy and financial planning. In 2023, we continued to incorporate certain aspects of sustainable finance and financed emissions within our financial planning process. We do not fully disclose impacts from climate-related opportunities on financial planning and performance including on revenue, costs and the balance sheet, quantitative scenario analysis, detailed climate risk exposures for all sectors and geographies or physical risk metrics. This is due to transitional challenges in relation to data limitations, although nascent work is ongoing in these areas. We expect these data limitations to be addressed in the medium term as more reliable data becomes available and technology solutions are implemented.

Strategy (b) related to transition plan: We published our Group-wide net zero transition plan in January 2024. In this plan, we provided an overview of our approach to net zero and the actions we are taking to help meet our ambitions. We want to be clear about our approach, the change underway today and what we plan to do in the future. We also want to be transparent about where there are still unresolved issues and uncertainties. We are still developing our disclosures, including considerations of possible additional data in relation to our financial plans, budgets, and related financial approach for the implementation of the transition plan in the medium term (e.g. amount of capital and other expenditures supporting our decarbonisation strategy).  

Metrics and targets (a) relating to internal carbon prices and climate-related opportunities metrics: We do not currently disclose internal carbon prices due to transitional challenges such as data challenges. But we considered carbon prices as an input for our climate scenario analysis exercise. In addition, we do not currently fully disclose the proportion of revenue or proportion of assets, capital deployment or other business activities aligned with climate-related opportunities, including revenue from products and services designed for a low-carbon economy, forward-looking metrics consistent with our business or strategic planning time horizons. In relation to sustainable finance revenue and assets we are disclosing certain elements. We expect the data and system limitations related to financial planning and performance, and climate-related opportunities metrics to be addressed in the medium term as more reliable data becomes available and technology solutions are implemented. We expect to further enhance this disclosure in the medium term.

Impacts of transition and physical risk

Strategy (c) relating to quantitative scenario analysis: We do not currently fully disclose the impacts of transition and physical risk quantitatively, due to transitional challenges including data limitations and evolving science and methodologies. In 2023, we have disclosed the impairment impacts for our wholesale, retail and commercial real estate portfolios in different climate scenarios. In addition, we have disclosed losses on our retail mortgage book under three scenarios and flood depths for specific markets. For our wholesale book, we have disclosed potential implications on our expected credit losses for 11 sectors under two scenarios. We have also disclosed a heat map showing how we expect the risks to evolve over time.

Metrics and targets (a) relating to detailed climate-related risk exposure metrics for physical and transition risks: We do not fully disclose metrics used to assess the impact of climate-related physical (chronic) and transitions (policy and legal, technology and market) risks on retail lending, parts of wholesale lending and other financial intermediary business activities (specifically credit exposure, equity and debt holdings, or trading positions, each broken down by industry, geography, credit quality and average tenor). We are aiming to develop the appropriate systems, data and processes to provide these disclosures in future years. We disclose the exposure to six high transition risk wholesale sectors and the flood risk exposure and Energy Performance Certificate breakdown for the UK portfolio.

Metrics and targets (c) on targets related to physical risk: We do not currently disclose targets used to measure and manage physical risk. This is due to transitional challenges including data limitations of physical risk metrics. For retail, we do not use targets to measure and manage physical risk. In 2023 we introduced internally a global 'soft trigger' monitoring and review process for physical risk exposure where a market reaches or exceeds a set threshold, as this ensures markets are actively considering their balance sheet risk exposure to peril events. We also consider physical and transition risk as an input for our climate scenario analysis exercise.

We expect to further enhance our disclosures as our data, quantitative scenario analysis, risk metrics and physical risk targets evolve, and technology solutions are implemented in the medium term.

Scope 3 emissions disclosure

Metrics and targets (b) relating to scope 3 emissions metrics: We currently disclose partial scope 3 greenhouse gas emissions including business travel, supply chain and financed emissions. We currently disclose four out of 15 categories of scope 3 greenhouse gas emissions including business travel, supply chain and financed emissions. In relation to financed emissions, we publish on-balance sheet financed emissions for a number of sectors as detailed on page 18. We also publish facilitated emissions for the oil and gas, and power and utilities sectors. Future disclosures on financed emissions and related risks are reliant on our customers publicly disclosing their greenhouse gas emissions, targets and plans, and related risks. We recognise the need to provide early transparency on climate disclosures but balance this with the recognition that existing data and reporting processes require significant enhancements.

Other matters

Strategy (b) relating to access to capital: We have considered the impact of climate-related issues on our businesses, strategy and financial planning. Our access to capital may be impacted by reputational concerns as a result of climate action or inaction. In addition, if we are perceived to mislead stakeholders on our business activities or if we fail to achieve our stated net zero ambitions, we could face reputational damage, impacting our revenue-generating ability and potentially our access to capital markets. We expect to further enhance the disclosure in the medium term as more data becomes available.

To manage these risks we have integrated climate risk into our existing risk taxonomy, and incorporated it within the risk management framework through the policies and controls for the existing risks where appropriate.

Metrics and targets (c) relating to water usage target: We have described the targets used by the organisation to manage climate-related risks and opportunities and performance against targets. However, taking into account the nature of our business, we do not consider water usage to be a material target for our business and, therefore, we have not included a target in this year's disclosure.

With respect to our obligations under LR9.8.6R(8) of the FCA's Listing Rules, as part of considering what to measure and publicly report, we perform an assessment to ascertain the appropriate level of detail to be included in the climate-related financial disclosures that are set out in our Annual Report and Accounts. Our assessment takes into account factors such as the level of our exposure to climate-related risks and opportunities, the scope and objectives of our climate-related strategy, transitional challenges, and the nature, size and complexity of our business. See 'How we decide what to measure' on page 43 for further information.
