Unilateral relief meaning

What does Unilateral relief mean?
In practice, unilateral relief is the mechanism by which a UK‑resident taxpayer obtains credit against UK tax for foreign tax paid on the same income (and, in some cases, gains) where no relief is available under a double taxation agreement. In UK direct tax, the concept is statutory (including the foreign tax credit rules in TIOPA 2010) and generally operates as a credit limited to the amount of UK tax attributable to that income; it cannot exceed that cap or duplicate treaty relief. The taxpayer must evidence the foreign tax paid and meet source/matching conditions, with claims made through Self Assessment or the corporation tax return. For inheritance tax, unilateral relief is expressly provided by IHTA 1984, s 159, allowing credit where foreign death or transfer taxes are charged on the same property; the credit is limited to the UK IHT attributable to that property. Usage is consistent across England & Wales, Scotland and Northern Ireland. In Ireland, analogous unilateral relief exists under the Taxes Consolidation Act 1997, typically granting a credit for foreign tax where no treaty applies, subject to similar limits, evidential requirements and claim procedures.

UK competition law round-up: CMA provisional cloud findings favour DMCC SMS route; Growth & Investment Council Terms of Reference; Subsidy Advice Unit on film studio rates relief

Market studies CMA publishes provisional findings in cloud services market investigation; recommends new digital markets investigation The CMA has issued provisional conclusions from its market investigation into the provision of public cloud infrastructure services in the UK. The authority made a market investigation reference in October 2023, following a market study of the sector. In that study, the CMA judged there were reasonable grounds to suspect that a feature, or a combination of features, in the market for the UK supply of public cloud infrastructure services may prevent, restrict, or distort competition. It has provisionally determined that high levels of overall concentration, together with barriers to entry and expansion, have conferred significant unilateral market power on Amazon Web Services (AWS) and Microsoft across the UK cloud services market. The CMA also provisionally considers this market power to be further reinforced by various commercial barriers, notably egress fees, as well as by technical barriers, including the practical complications involved in effectively operating multi-cloud services. In addition, the authority has provisionally...

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...

UK IHT unilateral relief: credits for overseas succession taxes—conditions, situs, formulae, lifetime transfers, claiming and limitations (IHTA 1984 s159)

A unilateral credit against UK inheritance tax (IHT) can be claimed when property has been subjected to a tax comparable to IHT in a territory outside the UK. HMRC sets this out in the Inheritance Tax Manual at IHTM27185. Information for particular jurisdictions is available in the International Q&A guides—Private Client subtopic. When does unilateral relief apply? It chiefly operates for territories where double tax relief is not available. If the UK has a double tax treaty with the other territory, double tax relief for IHT applies instead. Both mechanisms aim to prevent the same asset being charged to inheritance or estate taxes in both jurisdictions. Double taxation can occur because: jurisdictions tax by reference to different factors (for example, the residence, domicile or nationality of the deceased or the heirs, or the location of assets). Some may apply more than one of these even where the basis aligns, definitions may vary (for instance, of movable and immovable property, or of asset location)...

UK double taxation relief: income, gains, employment, trusts, and inheritance tax—treaty and unilateral mechanisms, residence tie-breakers, and EU developments

International tax law International tax law primarily concerns states’ taxing rights. As with other areas of international law, the need to resolve these matters arises from jurisdictional conflict. Conflicts occur when more than one state claims the power to impose a similar charge on the same arrangement or transaction. There are two forms of double taxation: economic double taxation, which relates to continuity of the tax object (ie the same property being taxed), and juridical double taxation, which relates to continuity of the tax subject (ie the same person being taxed) and can be described as two or more taxes levied on the same property, on the same person, during the same period, for the same purpose Double taxation can be avoided or reduced under UK domestic law and that of other countries (see below Unilateral relief—income and capital gains), as well as through double tax treaties (DTTs). The Organisation for Economic Co-operation and Development (OECD) has developed a model DTT...
