P11D & Form 42 Returns Now Due
7th May 2026
Although a business may have an accounting year which doesn’t end on 5 April each year, they will still be required to submit various returns to HMRC on a tax year basis.
Compliance is now an extremely important aspect of any business, with deadlines, fines and indeed penalties being applied where dates are missed, or information is incorrect. In the next couple of months, the following business-related returns will be due.
Form 42
If you’re an employer operating a share scheme on behalf of your employees or have carried out other employment-related securities transactions, you may need to notify HMRC and submit an ERS return, also known as a Form 42.
The Employment Related Securities return should be submitted online by 6th July following the end of the tax year and can be done by either the employer or an agent. The next deadline is 6th July.
There are late filing penalties for returns filed after 6th July and potential penalties for errors.
You’ll still need to submit a return if there are no share or security transactions during the tax year, and for as long as you operate the share schemes. Also, even if HMRC doesn’t issue you with a reminder, you should submit a return if you’re still operating employee share schemes.
Form P11d
At the end of the tax year you’ll need to submit an end-of-year form to HMRC for each employee you’ve provided with expenses or benefits. The form will either be a P9D or a P11D, depending on the expense or benefit.
You may need to submit form P11D(b) to report the amount of Class 1A National Insurance due on all the expenses and benefits you’ve provided.
You should do this if:
- you’ve submitted any P11D forms
- you’ve been sent a P11D(b) form by HMRC
If you don’t submit any P11D forms but you’ve been sent a P11D(b) by HMRC to complete, you can tell HMRC that you don’t owe Class 1A National Insurance by completing a declaration.
The deadlines are as follows:
| What you need to do | Deadline |
| Submit your end-of-year forms (P9D and P11D) online to HMRC | 6th July |
| Give your employees a copy of the information on your forms | 6th July |
| Tell HMRC the total amount of Class 1A National Insurance you owe on form P11D(b) | 6th July |
| Pay any Class 1A National Insurance owed on expenses or benefits | Must reach HMRC by 22nd July (19th July if you pay by cheque) |
