Hui Ling McCarthy QC

Called 2005

Silk 2018

Tax Junior of the Year – Chambers Bar Awards 2013 and 2017, nominated 2016

After reading Mathematics at Durham, Hui Ling began her career in corporate finance in 2001 at US investment bank Bear Stearns (fondly remembered) where she received a solid grounding in accounting, finance and the 100-hour working week. She was first attracted to the tax bar under the erroneous belief that it was all numbers and Perry Mason. Albeit wrong on both counts, she was nevertheless undeterred and has rapidly built a strong contentious and advisory practice.

Hui Ling appears regularly in significant, high-value cases including:

  • representing the pension trustees in Equity Trust Singapore Ltd before the Court of Appeal involving tax and surcharges on £100m of funds under management. Lloyd L.J. described her submissions as “conspicuously able” [41];
  • acting for the 24 Claimants in Derrin Brother Properties in the High Court in relation to enquiries by the ATO with tax at stake of AUD 230m. Simler J. described her arguments as “admirable and forceful” [80];
  • securing what the Financial Times called “an important legal victory” for the government in the SDLT avoidance case, Vardy Properties; and
  • representing five lead case LLPs in the £300m Icebreaker litigation (with Jonathan Peacock QC).Hui Ling also advises a range of corporate and private clients in all areas of tax law with an emphasis on business / corporate taxation, VAT and SDLT. Recent corporate work includes advising on capital allowances, company reconstructions and issues concerning loan relationships and derivative contracts. Recent VAT work includes single/multiple supply and supply classification issues, partial exemption issues and Fleming claims. Recent private client work includes advising on tax issues concerning sportsmen, entertainers and event sponsors, partnerships, pensions, investments and remuneration.She has a particular interest in cases raising avoidance / abuse of rights, human rights or accounting issues as well as an interest in innovative tax dispute resolution processes, which led to her become chambers’ first CEDR accredited mediator in 2011.Hui Ling has served with the Officer Training Corps of the Territorial Army for 3 years. She has also run the 151-mile Marathon des Sables, rafted through the Amazon and swum the Channel in a relay, all of which she describes as “fun”, though noticeably only after the event.
