These benefits or ‘Benefits in Kind’ are perks/benefits which an employee or director has received in addition to their salary and can incur Class 1A National Insurance contributions – which are currently at 13.8%.

Another form, the P11D(b), is also sent with the P11D form which shows how much National Insurance is due on the benefits.

When is the P11D due?

A P11D form needs to be submitted for each tax year and is due for submission by 6th July following the end of the tax year. Any late submissions will incur a penalty of £100 per month from HMRC until the form is filed.

What needs to be included?

Some of the most common benefits that will need to be included on the form are:

• Company cars and/or fuel for private use
• Mileage – above the approved rate from HMRC
• Health insurance such as private medical or dental insurance
• Low or interest-free director loans that exceed £10k
• Staff entertaining over the £150pp threshold

What if there aren’t any benefits to report?

If there aren’t any benefits to report then a nil P11D form must be submitted to HMRC.

When are the payments due?

If there’s a payment of Class 1A NICs due, the company will need to make this payment to HMRC by 19th July.

P11D on self-assessments

If you have a P11D then these figures will also need to be included on your self-assessment tax return. So, it’s important you don’t file your self-assessment for that tax year before the P11D is submitted.
