October 2024

If we are already dealing with this matter on your behalf you need take no action.

Is this relevant to you?

This deadline is only relevant for those individuals who complete a 'paper' self assessment tax return and who are employees. Where you have an underpayment you may request that HMRC collect the tax outstanding by making an adjustment to your tax code for the year 2025/26.

Please note that where your return is submitted online then the filing deadline for 'coding out' is 30 December 2024.

November 2024

Is this relevant to you?

This deadline is relevant to employers who provide any employees with the use of a car. The form P46 (car) only needs to be completed where a car is first provided or an additional car is provided, or an employee ceases to have the use of a car without replacement. The completion of the form enables HMRC to amend the individual’s coding notice to reflect the change in benefit. This notification may be made by completing and printing off the relevant by paper or online forms.

Where one car is merely replaced with another, this may be notified online.

A change in car for car benefits which are being 'payrolled' should not be reported on a P46(car).

Is this relevant to you?

Where the payment is made electronically the deadline for receipt of cleared payment is 22nd November 2023. Interest will be charged if payment is made late. Penalties also apply.
