Given that swine flu is back in the news today, one potential issue is that employers might want to instigate checks and make them available to their employees in an attempt to respond to it, particularly in the autumn when there are likely to be concerns about swine flu again. In clause 55, it appears that an additional check in the course of the year would be taxable. I understand why it is not addressed in the legislation, but would the Treasury be willing to reconsider if concerns about swine flu increased and such checks became widely available?
