Ghastly situation with nil P35

With some trepidation I went to HMRC's website on 8th April and entered a nil return for one of my clients in respect of the P35.

I immediately received an email acknowledging receipt. This email told me I would get a confirmation email when my client's records were updated.

You won't be surprised to hear that I have heard nothing further from HMRC. When I look at this client's record on HMRC's website apparently no return has been filed. I emailed the online helpline to ask them to help but they referred me to the Employers helpline.

I was answered this morning within 1 ring by the dedicated Agents helpline - wow! An intelligent person told me that the best thing would be for me to try the ordinary Employers' helpline. He didn't seem to be able to do anything. I asked him why it was down to me when I had done what I was told I needed to do. I explained my concern about the company being accused of not having filed the P35 on time and he agreed it was a problem.

So having a dedicated Agents helpline is no use to us either.

Has anyone else had experience of using the website to file a nil P35?
