Issues for advisers to consider this month include: the 2011/12 P11D filing deadline of 6 July has now passed but HMRC will not charge a late penalty return unless the failure to file extends beyond 19 July; the first instalment payment of corporation tax, where a company has a calendar year accounting period, is due by the 14 July; and companies paying tax at the main rate with a reporting period ended June or July will need to pay particular attention to the progress of this year’s Finance Bill to make sure they use the correct substantively enacted rate for deferred tax purposes.
