Key tax dates for 2026/27
Every deadline that matters for sole traders, landlords, employers and limited companies in the 2026/27 tax year, in one place.
The 2026/27 tax year runs from 6 April 2026 to 5 April 2027. These are the dates we diarise for clients. Where a deadline falls at a weekend, HMRC generally expect payment to arrive by the last working day before it.
