By when are P11D and P11D(b) forms required to be submitted to HMRC?

The P11D and P11D(b) forms must be submitted to HMRC by July 6th following the end of the tax year, which runs from April 6th to April 5th. This deadline is critical for employers who need to report expenses and benefits provided to employees, which may affect tax liabilities. The timely submission of these forms ensures compliance with tax regulations and prevents any potential penalties that could result from late filing.

Other dates listed, such as June 30th, July 31st, and August 15th, do not align with the established HMRC deadline for these specific forms. Understanding this timeline helps businesses maintain accurate records and adhere to tax regulations as stipulated by HMRC.
