Legislators expressed reservations yesterday over a proposal to remove tax concessions for company cars. Criticising the proposed legislation as ineffective and unfair, they said the Government should introduce other measures to combat traffic jams. Chan Kam-lam of the Democratic Alliance for the Betterment of Hong Kong said the ending of tax breaks for company vehicles could increase the operating costs of public utility firms. 'They rely on their cars to provide services for the public. However, it may have little effect in easing the traffic,' he said. Liberal Party legislator Selina Chow Liang Shek-yee said it was unfair to single out company cars. Under the Inland Revenue Ordinance, businesses can claim initial and annual depreciation allowances and the running costs of their cars in computing their profit tax liabilities. The Government proposed last year to amend the ordinance to revamp such concessions.
