Double taxation meaning

What does Double taxation mean?
Double taxation describes the same income, profits or gains being taxed twice, typically in two jurisdictions—for example, tax withheld at source and a further tax on receipt. It can be juridical (the same taxpayer taxed on the same item by two states) or economic (the same profits taxed in different hands, such as corporation tax on company profits and income tax on dividends). The term is descriptive rather than a defined statutory expression, but relief is created by legislation and double taxation agreements (DTAs/treaties). In the UK, relief for foreign tax and the effect of DTAs are provided under the Taxation (International and Other Provisions) Act 2010, with DTAs given force by statutory instruments (Double Taxation Relief Orders). In Ireland, comparable relief operates under the Taxes Consolidation Act 1997, with DTAs implemented by statutory orders. Both systems broadly follow the OECD Model. Key features and practice points include: determining residence (tie‑breaker rules), identifying a permanent establishment, allocating taxing rights, applying reduced withholding tax rates on dividends, interest and royalties, and claiming foreign tax credit, exemption or deduction. Relief is typically obtained via self assessment, withholding tax reclaims, or the mutual agreement procedure. Usage and principles are consistent across England & Wales, Scotland,...

UK Double Tax Treaties: In-force, Pending and Signed—Status, Statutory Instruments, and BEPS MLI Synthesised Texts Tracker for Income and Corporation Taxes

Double tax treaties (DTTs) have a dual nature. They function simultaneously as: international agreements between contracting states, and elements of a contracting state’s domestic law For a DTT to take effect, each contracting state must: sign and ratify the treaty, and incorporate the treaty’s provisions into its domestic legislation In some jurisdictions, a DTT is given automatic domestic effect as soon as it is signed and ratified. Elsewhere, including the UK, a further legislative step is required. In the UK, the arrangements set out in a DTT (and any amending protocol) are brought into domestic law as schedules to Orders in Council and are published as statutory instruments (SIs). After the DTT has taken effect in the domestic law of both the UK and its treaty partner, and any additional formalities or procedures required by the DTT (such as exchanging diplomatic notes) have been completed, the DTT will come into force. The treaty will...

Irish Court of Appeal: US-owned Irish subsidiaries denied US–Ireland treaty benefits and s.411 TCA 1997 group relief; fiscally transparent US parent not ‘liable to tax’

Court of Appeal judgment – 27 May 2025 Because Susquehanna International Securities Ltd and two affiliates sit beneath a disregarded Delaware vehicle that bears no tax liability, the Court of Appeal (27 May 2025) held they fall outside the scope of the US–Ireland double-taxation treaty. Consequently, the Susquehanna entities cannot invoke the treaty’s equal treatment clause to claim an Irish tax relief reserved for residents of the European Economic Area, the court ruled. The companies had sought to rely on Section 411 of the Taxes Consolidation Act 1997, which permits tax relief to be surrendered within companies, the judgment noted. The court stated: ‘The central issue between the parties is whether it is material that the taxpayers’ parent is treated as fiscally transparent for the purposes of US tax law’...

Masters v HMRC: FTT: SIPP withdrawals post defined benefit transfer retain sufficient employment link under UK–Portugal DTC Art 17; taxable in Portugal; obiter: Art 20 requires actual taxation.

What are the practical implications of this case? The central question on this appeal was whether the pension drawdowns were ‘paid in consideration of employment’. HMRC argued that moving occupational pension entitlements to a SIPP, essentially an investment product that does not require employment as a condition, severed the necessary link to the original employment and meant the pension could be taxed in the UK. As many of the UK’s DTCs with other jurisdictions include wording similar to the UK–Portugal DTC, the outcome may have significant consequences for expats whose situations resemble that of the appellant. The First-tier Tribunal Tax (FTT) offers helpful clarification of the principles to be applied when deciding whether there is a sufficiently strong connection between an expat’s pension withdrawals and their former employment in such cases...

UK corporation tax on foreign profits for UK-resident companies: treaty and unilateral credits, limits and unrelieved foreign tax, deduction option, permanent establishment attribution, foreign branch exemption, and loss utilisation

Many UK-resident companies are expected to operate solely within the UK, with their entire customer base and supplier network located here, so that all profits and gains arise from UK activity undertaken domestically within national borders. Nevertheless, this is not universal; for a sizeable proportion of UK companies, overall profits also comprise non-UK amounts earned from activities outside the UK...

OECD Pillar One: Amount A profit reallocation and Amount B transfer pricing—scope, nexus, allocation, MLC implementation, tax certainty and Digital Services Tax withdrawal

In October 2021, countries participating in the Organisation for Economic Co-operation and Development (OECD)/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS) (the OECD Inclusive Framework) endorsed a ‘two-pillar’ package addressing the tax issues stemming from the digitalisation of the global economy. The two pillars constitute an ambitious effort to reform and modernise international tax rules that allocate where, and how, profits are taxed. Pillar One is chiefly (though not exclusively) aimed at the digital economy: ‘a world where enterprises can effectively be heavily involved in the economic life of different jurisdictions without any significant physical presence and where new and often intangible value drivers increasingly come to the fore’. Pillar One introduces two elements: a new taxing right that stretches beyond traditional tax nexus rules anchored in physical location (Amount A) a standardised methodology for transfer pricing baseline marketing and distribution activities between related parties (Amount B). This Practice Note provides a high-level summary of: the tax...
