Tax Authority or Taxation Authority meaning

Published by a LexisNexis Tax expert
What does Tax Authority or Taxation Authority mean?
In practice, this describes the public body that assesses, collects and enforces taxes and duties. It is a descriptive expression used across contracts and contentious tax matters rather than a single statutory term, though individual authorities are created by legislation. It means any governmental, fiscal or other authority (wherever located) competent to impose, assess, withhold, collect or enforce any liability to Tax, to issue rulings or clearances, or to administer related penalties and interest. Examples include HM Revenue & Customs (UK-wide taxes), Revenue Scotland and the Welsh Revenue Authority (devolved taxes), the Office of the Revenue Commissioners (Ireland/Irish Revenue), local authorities responsible for council tax and non-domestic rates (and in Northern Ireland, Land & Property Services for rates), and any successor or replacement body. Usage is broadly consistent across England and Wales, Scotland, Northern Ireland and Ireland. The term is typically encountered in tax warranties and indemnities, information and cooperation covenants, withholding and gross-up provisions, audit and enquiry correspondence, and dispute resolution with a tax authority.

Accumulation of trust income: when it becomes capital, beneficiary tax treatment, Trustee Act 1925 s 31 minors, tax pool and IHT implications (England and Wales)

See Q&A: At what point does income from a trust become accumulated and capital in nature, so that payments of the same funds are capital and the beneficiary cannot claim income tax back at their marginal rate? For present purposes, assume the trust is discretionary and that nobody has an interest in possession in its income. Accumulation denotes the transformation of income into capital; once that has happened, any later payments out of those same sums are treated as capital, and the beneficiary cannot reclaim income tax at their marginal rate. For income to be properly accumulated, certain requirements must be met: there must exist a power or trust to accumulate, granted by the trust instrument or under the Trustee Act 1925 (TA 1925), or possibly arising at common law—see Lombe v Stoughton (1841) 12 Sim 304 (not reported by LexisNexis®UK) There is also statutory authority to accumulate income from funds held for a beneficiary who is a minor, to the extent...

UK income tax treatment of interest in possession trusts: computation, rates (including trust rates), allowable deductions, and the 2024–25 de minimis income rule

General principles The trustees are, for tax purposes, regarded collectively as a single person, distinct from the individuals who serve as trustees from time to time. An interest in possession (IIP) means a beneficiary has an immediate right to the trust income as it arises. That income belongs to the beneficiary, and the trustees lack authority to retain it, save to meet proper expenses. Where trust income does not fall within the definition of accumulated or discretionary income in section 480 of the Income Tax Act 2007 (ITA 2007), it is treated as the income of ‘other persons’ and taxed at the basic and dividend rates. Ultimately, the income is assessed on the beneficiary at their personal rates, irrespective of when, and even whether, it is actually paid to them. Nevertheless, the trustees are liable to income tax on income arising from trust property because they are the legal owners of that property and thus the persons who receive the income. The way IIP and discretionary trusts are differentiated...

Transfer pricing between associated enterprises under double tax treaties: Article 9 OECD/UN Models, arm’s length standard, primary and corresponding adjustments, MAP, APAs, and Pillar One Amount B

Double tax treaties (DTTs) Double tax treaties (DTTs) are founded on the idea that members of a multinational group are charged tax as if they were independent, dealing with one another at arm’s length. To apply the separate entity concept correctly, DTTs allow jurisdictions to amend a group company’s profits so that any outcomes arising from particular conditions or relationships are removed for tax purposes. This is referred to as the ‘arm’s length principle’. Under Article 9 of the Organisation for Economic Co-Operation and Development (OECD) model tax convention (OECD MTC) and the UN model tax convention (UN MTC), contracting states may recalibrate the taxable income of ‘associated enterprises’ when their transactions are not conducted on arm’s length terms. The 2025 revised commentary to Article 9 of the OECD MTC makes clear that, when adjusting an associated enterprise’s taxable profits, a tax authority ought to apply the OECD’s Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations (2022) (OECD TPG), which set out comprehensive guidance on the arm’s length...

Death of employee option holders and shareholders: UK market practice, HMRC CSOP, EMI, SAYE and SIP requirements, tax treatment and practical issues

Employee share scheme participants and shareholders This Practice Note considers the matters that arise on the death of a participant in both HMRC tax-advantaged schemes and a range of unapproved share scheme arrangements. It also examines the practical points connected with the death of an employee shareholder who may have obtained shares under those arrangements. Market practice Early Vesting As a matter of market practice, in most employee share plans, death is ordinarily treated as a 'good leaver' event (see Practice Note: Drafting leaver provisions in share plans—Different treatment for different types of leavers). This typically results in accelerated vesting or the ability to exercise awards being triggered. Where that applies, and the relevant scheme is an option plan, the deceased participant’s personal representatives are permitted to exercise options within a defined window (commonly 12 months after death). Likewise, options already vested will generally have to be exercised within a specified timeframe from the date of death, failing which they will lapse and cannot be exercised...

NRB trust IHT 10-year charge: RPI-linked debt; excepted settlement

How should the trustees report the amount of the debt for the purposes of IHT ten-year charge? Should they include any index-linked element of the debt? We have found no authority directly answering this. The principal, or ten‑year, charge is imposed on the value of relevant property held by the trustees immediately before the ten‑year anniversary (TYA). See Practice Note: Relevant property trusts—the principal (ten‑year) charge. Where the trustees’ asset is encumbered by a charge with an index‑linked feature, the trust fund must be valued correctly just before the TYA. That exercise turns on the precise balance outstanding at that point and on whether the index‑linkage ought to be reflected, notwithstanding it would only bite once the loan is redeemed. As a broad rule, where property is charged, the amount secured is deductible from the property’s value when computing the IHT charge (section 5(3) and sections 162–166 of the Inheritance Tax Act 1984 (IHTA 1984)). There are, however, limited departures from that general position. Consequently, the amount to be...
