Her father, who died in 2002, was domiciled in Kalania.– 1999 – Moved to the UK and has lived and worked here since then.– 2001 – Subscribed for 100% of the ordinary share capital of Reef Ltd.– Intends to sell Reef Ltd and return to live in the country of Kalania in 2012.– No income apart from that received from Reef Ltd.Reef Ltd:– A UK resident company with annual profits chargeable to corporation tax of approximately ￡70,000.– Four employees including Coral.– Provides scuba diving lessons to members of the public.Payments from Reef Ltd to Coral in 2007/08:– Director’s fees of ￡460 per month.– Dividends paid of ￡14,250 in June 2007 and ￡14,250 in September 2007.Pension contributions:– Coral has not so far made any pension contributions in the tax year 2007/08 but wishes to make gross pensioncontributions of ￡9,000.– The contributions are to be made by Reef Ltd or Coral or a combination of the two in such a way as to minimisethe total after tax cost.– Any contributions made by Coral will be funded by an additional dividend from Reef Ltd.House in the country of Kalania:– Beachfront property with potential rental income of ￡550 per month after deduction of allowable expenditure.– Coral will use it for holidays for two months each year.The tax system in the country of Kalania:– No capital gains tax or inheritance tax.– Income tax at 8% on income arising in the country of Kalania.– No double tax treaty with the UK.Required:(a) With the objective of minimising the total after tax cost, advise Coral as to whether the gross pensioncontributions of ￡9,000 should be made:– wholly by Reef Ltd; or– by Coral to the extent that they are tax allowable with the balance made by Reef Ltd.Your answer should include supporting calculations where necessary. (9 marks)
(b) (i) Explain, by reference to Coral’s residence, ordinary residence and domicile position, how the rentalincome arising in respect of the property in the country of Kalania will be taxed in the UK in the tax year2007/08.

共用题干Water一the Issue of This CenturyThe world is running short of freshwater. Populations are growing bigger and thirstier （渴的）,with the result that freshwater is becoming increasingly scarce（缺乏）.Half the world's wetlands have disappeared during the last century,while estimates suggest that wa- ter use will rise by 50% in the next 30 years.The World Bank report estimates that as much as half of the world's population,concentrated in Africa,the Middle East and south Asia,will face“severe water shortages”by 2025.Local water conflicts and the loss of freshwater ecosystems appear large in some re- gions.A similar picture emerges from the globe's salt water regions. Three-quarters of the world's people may live within 100km of the sea in 2025,putting even more pressure on stretched coastal ecosystems. Two thirds of fisheries（渔业）are exploited at or beyond their sustainable limits, and half the world's coral reefs（珊瑚礁）may perish in 100 years. Almost 60% of coral reefs and 34% of fish species are at risk from human activities,the Bank says.The report concludes that there is ample evidence to justify immediate and coordinated action to safeguard supplies and use water more efficiently.Fresh water consumption is rising quickly,and the availability of water in some regions is likely to become one of the most pressing issues of the 21st century.A third of the world's popu1ation一around two billion people一live in countries that are experiencing moderate to high water shortages.That proportion could rise to half or more in the next 30 years unless institutions（制度）change to ensure better conservation and alloca- tion of water.China is one country where the portents（征兆）are gloomy. The most waterstressed country in East Asia,China is exploiting 44%of its usable water,a figure projected to rise to6O%by 2020.Primary withdrawal of water of more than 60%is widely considered by water experts to exceed the environmental carrying capacity of a river basin system. AlthoughChina's total use appears still to be reasonable,it has several basins that are severely stressed environmentally.Withdrawals exceed environmental limits in Afghanistan and Pakistan,and will exceed them in India by 2020.In the Middle East and North Africa,only Morocco has unexploited water resources.The rest have exceeded environmental limits and many are mining aquifers （蓄水层）一bodies of water-bearing rock一the report says.Most of the world's population may live within 100km of the sea in 2025.A: RightB: WrongC: Not mentioned
