TAX MAN TALKS TOUGH ON TAX-FREE TAXIS... Companies sending staff home in a taxi after they have worked late could soon find themselves with a hefty tax bill and possible fine. Professional services firm PricewaterhouseCoopers (PwC) has warned that HM Revenue & Customs is taking a more aggressive stance on the enforcement of tax rules. There are times when late-night taxis can be tax-free if certain conditions are met. For example, after 9pm, up to 60 times a year per employee and only if the late working occurs irregularly. Having a heavy briefcase or travelling home in the dark are not grounds to claim tax-free taxis, PwC said.
