The P9X form is used to notify employers of the tax codes to use for employees. The basic Personal Allowance for the tax year starting 6 April 2019 will be £12,500 and the tax code for emergency will be 1250L. The basic rate limit is £37,500 except for those defined as Scottish taxpayers who have a lower basic rate limit as well as an intermediate rate.
As a result of the increase in the basic Personal Allowance, there will be a general uplift of tax codes with suffix ‘L’ which have increased by 65. Employers should add 65 to any tax code ending in L, for example 1185L will become 1250L. The new form P9X is available online on GOV.UK to download or print.
The P9X (2019) form also includes information to help employers in the new tax year. The document also reminds employers that have new employees starting work between 6 April and 24 May 2019 and who provide a P45, to follow the instructions at www.gov.uk/new-employee. HMRC’s guidance has recently been updated.
